After 3 full days using the Sennheiser Momentum 3 Bluetooth Headphones heavily, they are remarkably sublime. This is a long review and I apologize in advance. If you’re going to spend $400 for state-of-the-art Bluetooth headphones, I hope this helps you. This review covers; Design/Build Quality, Features/Comfort, Bluetooth/Codec, Smart Control App, Battery Life, Noise Cancellation and most importantly SOUND. I’ve owned several high-end Bluetooth headphones. I much prefer over-the-ear design. I find them more comfortable, better sounding and way more immersive. For the last three years I’ve been using a pair of high-end Bluetooth headphones with noise cancellation. I thought they were really, good. That was until I got the Sennheiser Momentum 3 Headphones. The headphones come nicely packaged and included in the box is a USB Cable with USB-C connectors and USB adapter for USB-C to USB-A if you don’t have USB-C capabilities. You get a proprietary analog audio cable with 3.5 mm jack which is about 1.5 meters long. Also included is a soft carry case and a quick start guide. The first thing they suggest you do when you get them is to charge them fully. Then you download the Sennheiser Smart Control app for iOS or Android. The first time you open the headphones to turn them on they automatically go into pairing mode. If you have a device which supports NFC (Near Field Communication), the connection is automatic. If your device doesn’t support NFC, you simply go into Bluetooth settings on the device to pair them. DESIGN/BUILD QUALITY These headphones are retro-modern if there is such a word to describe them. The ear cups and headband are beautifully wrapped in supple and soft sheepskin leather (no fake PU leather on these puppies – no sir) attached to matte black metal. They are nicely padded and generously sized to fit just about any size ear. My ears don’t touch the inside of the ear cup, which is a first for any headphone I’ve ever owned. Adjusting the headphones to your head is accomplished by a simple, but elegant stainless-steel band you simply slide up and down. Many competitors to Sennheiser use a lot of plastics in their build. Many don’t offer leather either. The sum of all the parts of leather and steel in these Momentum’s looks and feels very high-quality, which should last for many years. COMFORT/FEATURES: These headphones are super comfortable. Wearing them for hours is great. They don’t put pressure on your ears or your head. The sheepskin ear cups are simply sublime in my opinion. Unlike fake leather, which can feel hot very quickly, these never felt even warm. There is no power button on the headphones. To turn them on, you unfold them, and they instantly turn on. To turn them off, you fold them, and they instantly turn off. And when they turn on, there are voice prompts to let you know their status, such as “Power On,” “Power Off” or “Device Connected.” When you take the headphones off, they pause instantly. When you put them back on, play resumes. All the controls are buttons on the right ear cup. My previous Bluetooth headphones were touch control. I’m so grateful these are not. If you’ve ever had touch-controlled headphones, it may seem cool at first. But just touching the controller on them often brings unwanted actions, like moving to the next song when you didn’t want to or pausing the music. Having real physical controls makes so much more sense and the layout simple, intuitive and very easy to use. You get a button to control ANC (Active Noise Cancellation) which includes three levels – Max Mode, Anti-Wind Mode, which lets in enough of the outside world when you may need it, and Anti Pressure Mode, which reduces pressure on ear and was actually my favorite mode. You can turn ANC completely off if you prefer. The other buttons are volume up/down, multi-function for music and calls and voice assistance buttons. There are separate microphones for ANC and for phone calls. Phone calls I made with the headphones were uniformly excellent. Callers were completely unaware I was using headphones – Nice! BLUETOOTH/CODEC The Momentum 3 headphones are Bluetooth 5.0. Bluetooth 5.0 is the newest Bluetooth standard and is very Low Energy (LE), meaning it won’t run your connected device battery down if your device is 5.0. The newest generation devices are 5.0, but if you don’t have a 5.0 device, no worries, your headphones will work just fine, as these are backward compatible. In terms of connectivity, these headphones can be paired with up to 8 devices. Remarkably, they will pair automatically with the last two devices they were paired with at the same time. WOW! You can move seamlessly from, say your iPhone to your iPad, without having to unpair and pair again. If you connect to a 9th device, the least used device will be unpaired. Still, having the ability to pair with eight devices, two of which are simultaneous is astounding! The Momentum’s come with the following Codecs: aptX, aptX LL, AAC, SBC. What difference does this make? These are the most advanced compression's for lossless audio streaming. aptX is not available on iPhone but is available on other makes. Apple uses AAC (Advanced Audio Coding) and is the successor to MP3. Whether your device is aptX or AAC, it will simply sound better. SMART CONTROL APP: Go out to the App Store or Google Play Store and download The Smart Control App. It’s perhaps a too simple, but quite easy to use app. Once you’re in the app, you can control the equalizer (EQ) and Noise Cancellation. Adjusting EQ is too simplistic. You slide your finger around, which is easy, but doesn’t permit adjusting bass, mid and high frequencies separately. But since I personally found no adjustment was necessary at all, the app isn’t something I’ll use much, if at all. You can also turn on Transparent Hearing, which turns on the microphone if someone needs to get your attention. These headphones also come with Tile App compatibility. Since I’m already using Tile, I can track the headphones if I misplace them. If you’re not a Tile user, you will need to download the Tile App and set up an account, which is free. BATTERY LIFE: Momentum claims the battery lasts 17 hours. That is not industry leading, but it’s not bad either. Competition in the same class offer better battery life of anywhere from 20 to 30 hours. The pair of headphones I’m replacing offered only six hours, so 17 hours is a big step up for me. But if your battery dies, you can plug the Momentum in with the supplied 3.5 mm cable. It takes about three hours to fully charge the battery. NOISE CANCELLATION: There are other headphones in this class which offer more noise cancellation. If your primary reason to buy headphones is to be completely isolated from the outside world, then these may not be the headphones for you. I buy headphones to listen to music. Noise cancellation for me is not the determining factor. To that end, the three options you get with Momentum 3 are more than enough for me and then some. Max offers the most isolation from outside sounds. Anti-Wind is best if you’re outside and need to be aware of your surroundings. And Anti Pressure for me was prefect. SOUND: This is what it’s all about. And that’s the magic of Sennheiser sound. Sennheiser is a German company, founded in 1945. They are ALL about sound and introduced the world’s first open headphones in 1968, forever changing the world of headphones. To me, sound trumps ALL when it comes to headphones. Design, build quality, features, etc., aside (which are all excellent), this is where the Momentum's shine brightest. OMG - These puppies have bass. Deep bass. Full bass. Punchy bass. Well controlled bass. While these headphones are great for any musical genre, I’m mostly a classical music lover. When the organ In Camille Saint-Saens Organ Symphony is played, it is simply awe inducing. The same with the Canons in Tchaikovsky’s 1812 Overture. It can rattle your head, but in a great way. Vocals and instruments, such as guitar or piano are so natural sounding. Few headphones recreate the human voice naturally. I expected Sennheiser to get the human voice and instruments right and they did. To change it up, I listened to some songs from artists like Libera or Enya and everything was balanced and natural sounding. Another fun group, Caravan Palace, uses synthesizers and instruments and with the Momentum's, I heard things I’d never heard with other headphones. Many headphones over emphasize treble. which can easily become harsh sounding and fatiguing. The best reference monitor speakers may sound flat in comparison initially but sound more natural and can be listened to for many more hours. This is the case with these Momentum’s which makes for being able to listen for hours without listener fatigue. Is there anything I would change? Just a few things. It would have been more class leading if Sennheiser had put a bigger battery in for more than 17 hours of play. The included soft sided case won’t provide much protection, so I purchased a hard-shell case for more protection. The Smart Control App isn’t really all that smart. And finally, while you can see the battery percentage in the Smart Control app, I would have preferred to see battery percentage in the Battery Widget on my iPhone/iPad. The quick start guide isn’t very good, to be honest. Bu you can go out to Sennheiser.com and download the full user guide, which is much better. To be honest, if these are the only thing’s I can be critical of it’s pretty minor. So, there you have it. For $399, these are the best headphones I’ve ever listened to. I like how they look. I like how they’re built. I like how they feel on my head. And I LOVE how they sound. It just doesn’t get better than this and I can't recommend them enough!

Most of my Sennheiser product knowledge is predicated on my experiences with their professional broadcast audio equipment. Knowing they are a leader in that field, I was eager to try their commercial noise cancelling headphones. The MOMENTUM 3 lived up to my expectations...for the most part. Features - These headphones have some nifty tech features including auto on/off by simply "folding" (or unfolding) the headphones together. They also have a "smart pause" feature that will auto pause/play based on a magical sensor somewhere that determines whether or not the headphones are over your ears. - Sennheiser chose to stay with tactile buttons to control volume, skipping, ANC, etc. rather than the "touch sensors" that many other high end, designer headphone manufacturers are moving to. Personally, I prefer the touchpad concept over buttons. Nonetheless, the buttons are simple to locate/manipulate and the commands (volume, skip, hang up, etc.) are easy to remember. - One of the cooler features, in my opinion, is the TILE integration so you can find these headphones if you misplaced them. - Voice assistance is offered and worked just fine with Google Assistant, however, when I paired them with my laptop and streamed Google Music, Cortana was the default assistant and could not complete vocal commands like "play next." Active Noise Cancellation (ANC) - The ANC in these is very good. Not many of us have the option to truly test all the high end brand ANC headphones but I have used 4 other ANC headphones (including one set of in-ear buds) and while everyone argues between Bose and Sony for the "best ANC" these headphones offer better than average noise cancellation. - ANC options include an easy toggle switch for ANC OFF, ANC ON, and a toggle between "amplified ambient noise" and noise cancelling--essentially auto-pausing your music and letting you hear everything around you crystal clear and loudly without the need to actually take the headphones off. - With some ANC headphones, toggling noise cancellation on/off will impact audio quality. Not an issue with Sennheiser. I noticed very little if any change in audio quality between ANC on and ANC off. - On the day my headphones arrived there were Bobcats outside of my ground floor office working on a landscaping project that involved dumping/raking rocks outside my window for about 30 minutes. With ANC on and music at an average level, I hardly knew the landscapers were there. I also never heard the office phone ring :-) Design - Discreet, easy to use/remember tactile button controls on the right muff. USB-C connectivity/charging plus a mini cord for wired connectivity. The headphones come with a USB-C to USB-A adapter for charging if you don't have a USB-C charger. - The look of the headphones is "old school" with a durable metal bad mounted to the outside of each can. This "retro" look makes the headphones look a bit larger than normal on my bald head. - The cans have a very deep, soft, leather cushion. The band over the head is well cushioned and comfortable as well. - It is worth noting that the quality materials/construction adds some weight compared to "all plastic" headphones of the same size. They fit me very well and I have not had issues with the headphones slipping or my ears getting too warm. Audio Quality Here's where it call comes together... - The audio quality is very good with these headphones. My only complaint is that, compared to other comparable brands at this price point, the audio sounds "distant" rather than "front facing." As a result, I think Sennheiser inadvertently created a "muddy, behind you" sensation when listening to music. Audio is full and rich, but not super tight and crisp. Again, the auditory quality is very good and balanced (you get the bass, you get the midrange, you get the treble) but when comparing them side-by-side to other headphones, I found the sound sensation to feel like the sound was behind me rather than in front of me. - When used for calls and video conferencing, my audience sounded great, however, they said that I was a bit hollow (as if I were in a public restroom). - My test music included modern rock, modern alt, 90s hip hop, 80s rap, grunge and metal. With the default EQ, no one style sounded better than the other yet I found myself wanting to tweak the settings for each style. Fortunately there is an app for that...unfortunately that app is a bit lacking. App - The app is average at best. It has an EQ feature that is less than spectacular. I cannot manually set the EQ where I want it--where I set it for ALL my audio devices (home stereo, car, soundbars, etc.)--because they use a "curve slider" rather than just letting us adjust the low, mid, high manually. Again, while the overall audio quality of these is good, a better EQ could make these headphones sound GREAT. - The app also let's you control ANC settings that include MAX, ANTI-WIND and ANTI-PRESSURE (eliminates that "pressure in the ear" or "underwater" feeling some get with ANC). The app will also let you turn on "transparent hearing" which essential means whether or not you want to hear street noise while listening to music. Other This is the first pair of bluetooth headphones I have owned that "multi-paired" to devices. I use these in the office and paired them with my laptop to stream music. I also paired them with my mobile phone. Occasionally the headphones would cut out which I thought was a quality issue. It turns out, they were cutting out whenever I touched my phone. At first I thought this was cool--the headphones were smart enough to know which device to switch to automatically. However, it became a nuisance because of how frequently I touch my phone to read a text or acknowledge a message. Nonetheless, I am not sure if this is an intended "feature" or just "smart technology" but this knowledge may be useful for some. Overall Overall I would recommend these headphones because the design quality and tech features. The audio quality and ANC is very good. If you are a sound tweaker, however, you may find these headphones to be a bit limited as you struggle to dial them in to your preference.

Sennheiser definitely stepped up the game on this headphones and now it competes with the major brands on the features, sound quality, and pricing. This is my second Sennheiser headphone and I have never been a big fan of Sennheiser until now. The momentum 3 has changed my perspective on Sennheiser headphones. I own several other over-the-ear and on-ear headphones from major brands (price range $350-$550), so my experience is purely based on the 2018 and 2019 headphones that I current own from other major brands. Sound: The sound clarity is amazing and definitely on par with the ones I own. This sound clarity on this is amazing and I feel this is the best headset for vocals - hands down! As an audiophile I have to rate this based on the sound characteristics I generally look for, when rating a headphones/music system. It falls a little low on the bass, but again its one's personal choice (or trade-offs) on what you prefer - high bass with lower clarity or low bass with high clarity @ high volume settings. I prefer the later one on over-the-ear headsets. Frequency Range Frequency Values Comments Sub-bass 20 to 60 Hz - Great Bass 60 to 250 Hz - Good Low midrange 250 to 500 Hz - for harmonics - Great Midrange 500 Hz to 2 kHz - horn like quality - good - Great Upper midrange 2kHz to 4 kHz - sound trimbre -Great Presence 4 to 6 kHz - for clarity - GREAT!! Features: 1) It simultaneously connects to 2 devices and it switched from my ipad to phone when I received a call. Its supports Bluetooth 5 and I walked around (~80 ft before I saw a lag) my house and didn't have any issues with it getting disconnected or dropped calls. I used it for 14 hours so far and still have 20% battery remaining on it. Its rated for 17 hr battery life. 2) It turns Off when you fold the headset and there is no ON/Off switch. I just need to get used to folding it when I am not using it, so I don't drain the battery. Also, it pauses the music when you take the headset off. 3) It has the Tile support- device locator. I had to use my Tile app and configure it to detect the "momentum 3" headset as one of the recognized devices on it. I tested the app, the phone vibrated with a low beep - not loud enough to detect if you are in a noisy environment, but the visuals on the phone are helpful (see the review pic) 4) Android App - The app has all the necessary description on how to use the controls, so you don't have to google it if you forgot on how to pair it with a new device, etc. It has equalizer settings that I played with and tested it for different settings - movie, music, etc. I cranked up the bass to its max setting and it still maintained the fidelity (i.e. not muffled) on the vocals. 5) Active Noise Cancellation (ANC)- This headset has a switch for turning it ON/Off and has a transparent mode to enable you to hear the outside noise. The app itself has 3 other settings for ANC - good for using it on the plane (check the pics). Overall it fell a little short on this feature when I compare it with my other headsets. There is some more work that needs to be done to improve this feature, to be on par with the best ones on the market. I didn’t have any issues with phone conversations in the noisy environments, but I rate it below the ones' I currently own, on this feature. 6) It has voice assistant and lets you connect to Alexa - haven't tested this feature yet. Am more of a google assistant person. Overall I like this headphones and definitely recommend it - Built off of high quality material, nice supple leather, very comfortable to wear it for long hours. My only complaint is the case - wish they provided a hard case instead of the cloth one. One other thing I noticed is the Aux cable that comes with it - it’s a proprietary cable and has a "twist lock" to keep it from snapping off, so don't lose it! This headset is definitely a good bang for your buck and falls in the high end price range with one more new option to choose from the existing brands in the market! - Good job Sennheiser !!

Pros: By far, the best sounding headphones I have ever heard for wireless bluetooth models of any kind! These things blow the Sony and Bose noise cancelling models out of the water in terms of sound quality. They just sound rich and full of bass. I listen to hip-hop, metal / punk / hardcore, and lots of electronic music. All sound great! Even right out of the box, without using their app on your phone (in my case Android - LG v30), they have a really nice amount of bass. The app lets you control it more, going way overboard on bass if you want, i mean way too much bass, but never quite getting too distorted, the drivers in the earcups can seem to handle it. They are built solid. I mean these things are built like a tank, and it is a good thing, as the mechanism to fold them also is the only way to easily power them down. Watch out for you fingers though, as the little hinge can cut you if they fold over your fingers. But they are built great!! And they are super comfortable. The ear cups are pretty deep and don’t touch my ears!! I have fairly average sized ears, so your mileage may vary, but this is always an issue with my ears with ear cups that go over my ears. Not with these deep ear cups! These bad boys also will stay connected to 2 devices at once!! FINALLY!! Love this!! Case in point… I paired these with my Android LV v30 phone… installed app, upgraded the firmware thru the app, and later paired them with my Nvidia Shield media player. Basically you will get a little voice saying, “connected to phone 1” then, “connected to phone 2” (if you are nearby when you turn the headphones on)... I can then watch movies and shows via my Nvidia Shield TV streamer, including KODI stuff with surround tracks, and they sound phenomenal. But, I can also still get notifications on my phone. The only downside of this is, whatever is playing on my other connected device will be “auto-paused” while the notification from the other connected device pairs thru. You can stop this behavior from happening by just setting your phone to vibrate, at least on my Android devices. The sound quality is still pretty stellar for watching movies on my Nvidia Shield TV, and I did not detect any lag between movies/shows and what I was hearing on the headphones, including watching things that had DTS-X, and Dolby Atmos surround sound tracks. I mean these things sound great for watching movies early mornings and late nights! They seem to remember the equalizer settings setup in the app most recently too. I also found that plugging them in via USB-C cable directly to my USB-C port on my phone would give me slightly better audio quality, but not go as loud, but did however seem to charge my headphones from my phone battery. Was not expecting that, though it is a plus if you need to charge that battery in a pinch. Your touch controls still work while connected via USB-C to your device. Via wired connection these also sound great, especially if you have a high powered DAC. I happened to have these on my LG v30 phone, and when switching on my phone to that HiFi DAC on it, it sounded great on these headphones. You will not be able to make or receive phone calls, or control the audio via the headphone touch controls however. They unfortunately have a proprietary connector on the headphone side, more on that below in the cons section of this review. On the couple of phone calls I have made so far, callers said I sounded pretty good, certainly better than included earbuds that I was previously using. I did like that I could change the ANC to transparent mode, so I could talk and still hear the outside world while speaking. Cons - Now I know I am listing quite a few, but I also want to say, none of these things would detract me personally from not buying these, because the sound quality is so good!! If you spend $400 on a set of headphones, one would have hoped they would have at least provided a hard case. These headphones come with a pretty flimsy cloth case with zipper. I already have ordered a hard case to hold these, because this fabric/cloth case won’t do anything to protect your headphones in a bag with other things. If they are just in a backpack on their own they might be just fine, but at $400 they should have given this to us. The noise cancelling seems to only knock out background noise maybe 50-60 percent to my ears. I use these while using a really loud vacuum, and they just don’t cancel my vacuum out more than that. These just don’t knock out sound like the Sony WH-1000XM3, and the Bose QuietComfort 35. But, those don’t sound nearly as good as these Sennheiser, not even close if you like bass especially! Battery life - I really wish these had better battery life. Both the app and the headphones themselves will tell you how much battery life is left, but apparently only in increments of 20%... either saying “you have over 80% battery life”, or showing it to you via the app. Not sure why they went this route, but I would have preferred an actual percentage like most devices. The other thing is, these are rated for 17 hours of wireless battery life, but I find I am getting around maybe 10-12 hours on a full charge or so with ANC turned on, and forcing my phone to use Apt-X bluetooth codec. Luckily, after your first initial charge, they do charge up to 100 percent quickly, but make sure you use the provided USB-C to USB-C cable (and their provided adapter to USB-A for your charger if needed). At first I used my own USB-C to USB-A cable, and it seemed to charge much slower than using their cable. All in all, it seems to take about 2-3 hours to fully charge from when it is around a 40 percent state. I don’t know for sure, but I get the impression that the reason the battery life is not as good as the Sonny or Bose, is because these pack so much bass on them. They must have their own DAC on board that uses more battery power to deliver that bass. Folding design - While I do like how they fold, I don’t particularly like that there is no dedicated on-off button. While it has not happened to me when folding, I can potentially see a time where they either unfold in their case, draining out your battery. They should have just thrown in an extra power button that will override this behavior. Yeah.. you can use them with a cord, but they unfortunately are of a proprietary design on the right ear cup, and it is difficult to get in (you twist until it pops in). But once it is in, the sound can get even better than any of the bluetooth codecs can get. Just make sure if you are using them with a music app that it has a good equalizer to really make them shine to your liking. I really wish they used a standard plug on both ends. Plugging the cord in also sends the headphones into airplane mode, and bluetooth gets shut off. Now the real difficult thing is getting their proprietary cable out. It requires a lot of pressure to yank out, and everytime I feel like i am going to destroy the cable, or destroy the jack on the ear cup itself. I don’t know why they went this way with this. Con - Equalizer in the app. At first I thought it was ok, but for a company with such a great history making headphones with stellar audio quality, I wish they had made a true equalizer, and not what they went with which doesn’t seem to provide as much granular control. At very least I wish they had allowed you to save equalizer profiles that you can switch in the app. That would have been made it easier to swallow at least. It is just hard to remember that sweet spot if you jump between genres of music with these. It is a bit finicky setting just right. Another ding on the app on Android, and at least on my LG v30 with android version 9.0, you cannot tell what bluetooth audio codec is actually being used inside the app. I had to go into a android developer mode on my phone to see that it was not using one of the higher end codecs when connected. After physically clicking aptX, I could hear the sound quality get even better. I just wish they would let you do this in their app. Not sure why they can’t do the same with their android app. You can charge these headphones, and still keep using them, but I noticed they introduce a low hum while listening to them via bluetooth, and charging at once. The same happens when charging the headphones and using the wired connection to your device, there is still that humming. Overall, these are fantastic sounding, and very comfortable headphones. I know I listed a lot of cons, and my advice would be that if you value sound quality over the amount of noise cancelling, these are worth the extra money over the Sony and Bose options. I also find the build quality of these Sennheiser’s to be much better than the Sony and Bose. I personally like the way they look but they are definitely more noticeable than the Sony or Bose for sure. A more traditional headphone look. Recommended if you value sound quality and comfort over noise cancelling! Your ears will not regret it!

These headphones provide one of the best listening experiences. Audio is clear and detailed, very clear mid-tones, highs and enough bass. Design: These are around the ear headphones, which are larger and they rest on the head, surronding the ears, not resting over the ears. The headband is made of flexible metal, covered in leather with light padding. Hinges are also metal, and fold inwards (like eyeglasses) but not sideways. The button-like mounts between the earpieces and headband giving the headphones a classic retro look of studio headphones. Earcups are very soft and plush, leather. Controls and operation: After using many high-end Bluetooth headphones, these for me as the best in usability: - Unfolding the headphones turns them on directly, no button press necessary. It pairs with the phone right away. Folding one or both earcups turns it off. - Using sensors in the earcups, starts playing music within a second of putting the earcups on. Lifting one of the earcups or putting them around the neck pauses the music. For example, if need to talk to someone, simply lift the earcup and it pauses on its own. Also this puts the headphones in standby mode, but does not unpair from the phone, to save battery. - Controls are very simple, using logically placed buttons on the back side of the right earpiece: ○ Noise Cancellation control: Off, On or hear-thru (The hear-thru mode is a toggle on the same switch). ○ There is a spacing and then the volume up, play control and volume down buttons. § Like on many other headphones, the play button skips forward with two clicks and backwards with three clicks. The volume buttons serve only one function. Holding it for 2 second plays back the battery level. ○ The last button invokes the voice assistant when pressed once, and Bluetooth pairing when held. - Call control: If the headphones are around your neck, putting them on answers the call. Putting it back on the shoulder mutes it. The play button also answers and hangs-up. Holding it rejects the call. Pressing it twice switches call (Call-waiting, etc). Holding the volume down or up mutes or unmutes the call. - The noise-cancelling function can work without a phone connected. - The headphones come with an audio cable that can be used even when it ran out of battery (or use ANC in conjunction with the audio cable if it's on). Bluetooth: It checks all my boxes. State-of-the-art Bluetooth implementation: - Bluetooth 5.0 (better range and better battery with newer Bluetooth 5.0 phones). - It can connect to two phones at once. I was able to use both my iPhone and Android paired at the same time, but plays audio from one at a time, it does not mix the audio, which would've been better for me. Regardless, very few headphones connects to two phones at the same time. - Supports NFC pairing for Android phones. - Uses Bluetooth LE for app control. - Codec support: SBC (Standard), AAC (best for iPhones), and AptX/AptX low-latency for higher-quality on Android. Tile: - One of the very few headphones that support the Tile Bluetooth tracking platform. This is very useful when miss-placing the headphones. Tile can tell you if the headphones are nearby and make them play a beep, even when they are off. And because Tile has millions of uses, the headphones can be tracked if any other Tile user is nearby. It worked for me on both iOS and Android, even when not paired to the phone. Note that it took me a few tries to pair it initially using an older iPhone, but once I set it up worked fine. Alexa: - After using the headphones, received a firmware update notification. After updating them, I was given the choice through the Sennheiser app to switch to Amazon's alexa when pressing the assistant button on the headphones. Otherwise, it's Siri on iPhone and Google's on Android (Or whatever your phone uses by default). App: - The Sennheiser 'Smart Control' is very basic and simple to use. It looks and works practically the same in iOS or Android. It's used to check the battery, set Alexa if needed, firmware upgrades, some general settings for the headphones, the level of noise cancellation and the equalizer. - The equalizer is different than anything else I've seen: Instead of setting individual Eq bands, there is a single dot, that depending on where it's set on the page, it adjusts both bass and treble. It's the simplest I've seen and it's effective. Noise cancellation: The headphones already provide superb passive noise cancellation because it's a closed design. The ANC provides three levels. However I find that even at max, the active noise cancellation is not enough. If you're looking for absolute silence with active noise-cancellation, this is not for you. Observations: - The headphones charge via USB-C, which is the new USB standard, which is reversible and charges faster (depending on the charger and device). - It comes with an USB-C to USB-C cable, and also an USB-A to USB-C adapter, to connect to traditional USB chargers. It also comes with an audio cable. - Battery rated for 17 hours of music play. - A carrying case is provided also, which is padded, gray cloth, and find it very nice. - Sennheiser is a German company, with many, many years of experience in making headphones. And to my rejoice, are also manufactured in Europe (but not in Germany though). Final notes: Lackluster active noise cancellation notwithstanding, these are very solid headphones, with exquisite sound, and very solid construction, and albeit a bit heavy, feels very comfortable wearing them though the day. Battery life could be better for headphones this size, but is plenty for most uses, charging them about twice a week. Also note that these do not fold flat, so they took a bit more space than necessary. However these are impressive, solid headsets. Sennheiser sound does not disappoint. It's among the best sound on wireless headphones. Very rich, detailed sound. Neutral, balanced sound with very vivid delivery. I cannot stress how well it sounds, unless you're looking for overpowering extra bass, which is not my case.

Sennheiser is known for quality and the Momentum is no exception. I have been using these for about roughly two weeks give or take and I am very surprised by these headphones. In this review I'll give my opinion on the momentum headphones and how they perform in various scenarios. ::::General impressions::: I own plenty of headphones wired & wireless and was really looking forward to using these headphones. Upon opening the box you'll find your headphones in a nice carrying case with the following accessories included; 3.5mm cable and USB type C. Yep these have USB Type C to me that's a big deal because that's one less cable to carry when it's time to charge. The headphones come folded and as soon as you unfold them they begin to look for your device. I had already downloaded the application and it paired in more seconds. It was effortless and not to mention I had a full charge out of the box. How many devices normally are fully charged when you buy them? First time for me but so far I'm impressed. On the outer right cup you'll find a sticker with all the controls listed. Volume up and down and pause and the ambient noise button which is easy to use. It is the top button you just slide it down and the music pauses and allows you to hear what's happening around you without having to take the headphones off. And then the very bottom button you have the personal assistant button. I use a Note 10+ and you have three options that presents itself; Google, Alexa, and Bixby. I use Google and it works well for simple searches and whatnot. So far so good. These headphones sound good wireless and when you opt to use the wired. The Active noise cancelling works really well. I can use them and not hear anything when my girlfriend is nagging me. I also tested them outside on the Subway and they do a good job of drowning outside noise. I got used to the ambient button and don't take off the headphones. At first it took some time to get used to and I would take them off it is just a habit. I recommend turning off smart pause in the app it is annoying and pauses even if you take one side off to scratch your ear or adjust the headphones. I used them while working out I didn't like that because they cover the ear and I ended up sweating a little more than I liked but that's no fault of the headphones. :::Call quality::: Calls were clear and I was able to everything and the other party did as well. Like most headphones though using them outside while there is wind can be challenging. A mild or moderate stream of wind isn't a big deal but anything more than that the other party will struggle to hear you. :::Pros & Cons::: Pros - USB Type C charging port - Long Battery life - Great smartphone app - Super easy to use once paired just unfold and it immediately connects - Comfortable for long periods of use - Good sound quality wired & wireless. Cons: - I did not like the smart pause feature (thankfully you can turn this off in the app) TL;DR To summarize my review these are a top notch pair of headphones that are simple to use right out of the box. It uses USB type C to charge and can be used wired or wireless. It has long battery life, sounds great and is loud. There is an available smartphone app with some decent functionality that works really well and is just as simple to use. These are my daily headphones I use them whenever possible and also with my Nintendo Switch. There are plenty of other great headphones on the market but none are as easy to use as these are and all in all it is why I like them so much. Go and get a pair of your own they are that good.

Sennheiser Momentum 3 Wireless Headphones Setup: The instruction pamphlet will get you started. You will want to download the Sennheiser Smart Control application from either Google Play or Apple’s App Store. More on the app later. My headphones shipped 80% charged so were ready for use out of the box. I started by plugging them directly into my computer via USB-C and firing up my iTunes library. My thought is that I would charge them to 100% while breaking them in with my iTunes library. Later, I was able to easily connect the Momentum 3 to my computer and iPhone via the included proprietary three-way stereo cable. Bluetooth connectivity with my iPhone was equally easy to setup. Music: Highs, mids, and lows are clear. I played a variety of content including Electro Swing, K-Pop, easy listening, 70’s power ballads, alternative, rock, classical, and some popular videos including The Lord of the Rings: The Two Towers. Highs were high. Mids felt rich and clear. Low notes felt tight and detailed. And those low, powerful waves of base you get from movies felt satisfying when the Momentum 3’s were hard wired into my computer. The “Two Towers” over Netflix sounded pretty good for headphones. I started off my musical journey with Boston’s “More Than a Feeling”. I tested the music over Bluetooth and stereo cable connection using my iPhone and Apple Music. There is a difference in sound quality. Bass sounds deeper, highs sound clearer, and mids sound fuller on the stereo connection. I also noticed that the volume increased once I removed the stereo cable. Almost like the headset was trying to make up for the detail loss with increased volume. Again, everything was clear. I did this same A/B switch out with Sturgil Simpson’s Sound & Fury, Momoland’s “Bboom Bboom”, A Hat in Time & Plasma3Music’s “Trainwreck of Electroswing”, the “Ghost Busters” soundtrack, Lindsey Stirling’s album “Artemis”, Bach’s “Sanata for Flute and Continuo in E Minor, BWV 1034: II, Allegro”, and so on and so forth. In all instances, wired sound better than wireless. I expect this due to how awful Bluetooth is with music. Additionally, every selection, regardless of wired or wireless, had this behind my ear quality that sometimes worked and sometimes did not. The harder, punchier music could overcome this with more volume. But, softer tracks, like classical, could not. I was not left with the feeling that I could kick back and feel immersed in my music. I felt like the music was coming from behind me regardless of material, sound canceling status, or equalizer setting. I did a comparison with other quality headphones I own. This is unique to these Sennheiser headphones. It is not necessarily bad. It is just different. You will also need more volume to achieve the same immersive listening experience as other similarly priced headphones. The included cable is poorly shielded. I heard a buzzing sound over the cable while the iPhone was connected to the charging cable. This is the only headset I have that picks up this interference. I also have a wireless charging station for my gaming mouse. The stereo cable will pick up and transmit the frequency for the charging station if the cable is in proximity. It sounds like ping ping ping. This is not an issue for my other wired headphones. The cable is very thin and thus susceptible to picking up interference. Volume: The headphones require adjusting with every musical source without exception. Bard’s Tale IV is a video game available on Xbox Gaming for PC. It has an A+ professional soundtrack that I wanted to test these headphones with. I connected the headphones over USB-C. I adjusted the volume appropriately. Then I switched to a wired connected for my Apple Music on my iPhone. I had to adjust the sound again. I then moved to Wireless with my iPhone. I had to adjust the volume again. I can understand changing the volume between devices. But, having to adjust on the same device left me scratching my head. We are talking wild swings in volume between connection types. Switching back to any of my prior sources yielded the same experience. The Momentum 3 does not appear to remember volume levels between devices. This is a pain for me because I am always changing between devices for different reasons. I do experience differences in volume with other headphones in the same class as the Momentum 3s. However, the wide swings in volume are unique to the Momentum 3s. Smart Control App and Music Sources: Setting up the Momentum 3s with the Smart Control application was frustrating. My iPhone connected to the Momentum 3 without any issues during initial setup. The Smart Control app, on the other hand, kept dropping the connection. I had multiple experiences where the App would not connect to the headphones at all. The app did drop the connection very 10 to 15 seconds when it did make a connection. For example, I am listening to Bach’s “Le clavier bien tempere” through Apple Music over Bluetooth and have no access to the features of the app. I have this same issue when connecting with the stereo cable or USB-C. According to the app, Sennheiser is aware of the issue and is working on a fix. I hope they come out with an update soon. Otherwise, what’s the point of equalizer functions and multiple noise canceling options if you have to turn off your music, disconnect any wires, connect to the app, make your changes, and then turn everything back on to see if the changes are to your liking? The headphones can be used successfully without the app. Smart Control Appp: There are three settings: Active Noise Canceling, Transparent Hearing, and Equalizer. The app will also tell you the battery level. Active Noise Canceling will allow you to set Noise Canceling to Max, Wind, and Anti-Pressure. Max is exactly what it sounds like. This is the best noise canceling the Momentum 3 has to offer. The noise canceling is ok. It does block out the constant fan noise of my computer and some annoying background noises. It does a decent job of blocking out distant sounds like background conversations and moderate office background noise. I did use my Momentum 3 around my air fryer while crisping up some donuts. The volume of the air fryer was cut in half. Random noises, like keyboard key clicking, are somewhat muted. However, this is mostly due to the insulation provided by the ear cups and not the noise canceling qualities of the Momentum 3. I did not test the Wind setting. I only noticed that this setting allowed a lot of outside sound into the ear cup. Transparent hearing is a nice feature. This allows all outside sound to pass through the ear cups microphones into the ear cups without any processing. My audio source is automatically muted. I think this is the best iteration of this type of passthrough I have heard. I know it is the best of any headphones I own. The app allows me to modify this mode by allowing music to play, at a reduced volume, while transparency is turned on. I can see myself using this feature in the office when someone stops by to ask me a question. Last is the equalizer. The equalizer is an interactive image with a small round circle on a flat line. You move the circle with your finger around the screen to influence the curvature of the line. One way increases bass and treble response. Move another way and you enhance mids by sacrificing highs and lows. You will favor one range or another depending on how you move your finger. Hands free: The Momentum 3 is also capable of hands-free calling. I normally use either the wired ear buds that shipped with my iPhone or a wired stereo gaming headset that includes a mic boom. I get exception audio however I also hear the cable brushing up against my clothes. I tested the Momentum 3s by making a few phone calls. The feedback I received includes: Clear sound but my voice had a “speaker in the background” kind of quality. The quality was not as tight as I would expect from a dedicated directional mic. Hopefully Sennheiser can correct this when they fix their app. Physical Controls: The Momentum 3 ear cup controls are solid. There is a switch that controls noise canceling settings, volume, a button that controls voice communications with your virtual assistant, and a multi-function button located between the volume controls. The multi-function button controls play, pause, track forward, and track back. The Momentum 3 ships with a sticker on the right ear cup with a basic description of what each button does. The included instructions go in depth regarding the use of each button. The button placement is convenient and easy to use. The buttons are rubberized, comfortable, and easy to depress. Below the buttons are the USB-C connection and a proprietary stereo jack that locks the stereo cable in place. Folding the headphones for storage will turn the Momentum 3 off. There is no other “off” button. Removing the right ear cup from your ear will pause your content. However, this only works over wireless and USB. It also depends on the content. Taking the headphones off or removing the right ear cup from my right ear paused my desktop’s YouTube video playback. The video automatically restarted when I returned the ear cup to my right ear. This also worked with iTunes. However, it will not work with two programs simultaneously. Apple Music paused playback and replayed when connected over Bluetooth. Comfort: I cannot wear these headphones for more than two hours. The ear cups are very soft, are comfortable, and the ear cups are adjustable for any head size. Unfortunately, they place too much pressure on my jaw. And there is no way to adjust for this with these headphones. Overall, I am disappointed with my experience.

I’d say the Bose NCH 700 is my current top pick for a noise cancelling headphone at this time. I’ve tried pretty much every other pair under sun and the Bose is the most well rounded. Price - Both are currently $399USD at the time of this review. Design - I prefer the looks of the Bose while on my head. It’s more streamlined and minimalistic. The Sennheiser’s look more elegant with the steel and leather materials off the head, however the exposed wiring looks kinda funky on the head from a front view (hence why none of the promo pics show the model wearing these headphones from a front view. They’re always looking towards the side.) Also, the Momentum’s looks bigger on my head which is never a good thing when outside. Both are built well with no worries that one will break easily from normal usage. The Momentum’s takes the slight edge here with authentic leather on the ear-pads and headband. The Bose can fold flat which results in a much smaller profile when stowed away in its hard carrying case. The Sennheiser’s can also fold, but not flat. The carrying case is about twice the thickness of the Bose and it’s not a hard material so your headphones face a higher chance of crush damage while being in your bag. Controls - Bose went touch controls while Sennheiser retained the tried and true button configuration. Both headphones allow controls of your volume, play and pause media and call accept and hang up and hold. Both thankfully have a dedicated voice assistant button however the Bose allows for always on and listening Alexa. Both can toggle between ANC modes, but the Bose allows for 3 ANC presets switching while the Sennheiser’s allow for only ANC on or off and ambient mode. The Bose surprisingly doesn’t allow you to turn off the ANC from the headphone and you have to do that from the app. The touch controls on the Bose is pretty responsive and I don’t really have issues with it. The button controls on the Sennheiser’s is tactile and works as should. So it really depends if you prefer buttons or touch controls here. Comfort - I prefer the Bose slightly here. It’s lighter and just hugs my head with enough pressure to not fall off with any sudden head movements. The ear-pads opening is generous and allows my ears to go in all the way and not be clamped down. The Sennheiser’s is quite comfortable but they’re heavier and clamp a little harder on my head. I can wear both for 2 hours straight but the Bose just leaves my headphone not feeling as fatigued. Battery Life - Bose takes the cake here. Longer 20 hour battery vs. the Sennheiser’s 17 hours. Also, from a quick charge the Bose can receive a longer charge at 3 hours vs the Sennheiser’s 1.5 hours. Both charge via USB-C. Bluetooth - Sennheiser’s take the cake here in terms of codec support. NFC support is on the Sennheiser’s but not the Bose. They also support AptX-LL which is great for those who might want to play video games if they have a AptX-LL equipped receiver. Both support AAC and SBC, but the Bose does not support AptX. Connectivity and range has been pretty great on both and haven’t had any crazy issues while using both on the bus, subway, walking through NYC, at the office and at home. Both support 2 device connections. I prefer the Bose implementation because it switches between devices more seamlessly and the voice prompts tells you the name of the device it is connected to. The Sennheiser’s voice prompt just says “phone 1” or “phone 2” which isn’t really helpful if you have a desk with a MacBook Pro, iPad Pro and iPhone XS Max on it. Both can conveniently be put into pairing mode from one of the buttons on the control side of the headphone’s ear-cups. Call quality - Bose is still number 1 here. Callers continue to tell me they can hear my clearly despite me being right next to a bus engine on my commute to work. Meanwhile on the Sennheiser’s, callers said they can hear the bus engine and I need to speaker up louder in the same environment, but they can still hear me unlike the Sony WH1000Xm3 which is completely horrible in these situations. If you’re in a quiet to moderately loud environment, they’re both gonna do well. The Bose just sets itself apart in noisy environments due to the excellent microphone array and the ability to cancel our background noises. Both have a convenient feature to mute your microphone while on the call using the voice control button on the Bose and the volume down button on the Sennheiser’s. Features - Both do the basics for a 2019 premium ANC headphones. Bose has significantly more control over its ANC system (albeit a bit overkill). Also, there’s a preset button to toggle between 3 saved ANC presets leveraging on the fly adaptation to your environment. Sennheiser’s approach is to either have it on max or on with wind reduction mode or lower cabin pressure, off or transparency/ambient mode with the ability to have audio play as well or not. The ambient mode is slightly superior on the Bose. Simply sounds like I don’t have headphones on and every natural. The Sennheiser’s sound slightly digital but very good nonetheless. As for noise cancelling, Bose is easily superior. With the Sennheiser’s, I can still hear a decent amount of what’s going on around me while I’m commuting or walking through the city. With the Bose, the world literally melts away when the noise canceling is engaged and I can faintly hear what’s going on around me. When music is playing for the most part they will both block out everything around you typical in a commuting situation unless you listen at low volumes or there’s a quiet passage in the music, then the Sennheiser’s weaker ANC will cause loud outside noise to seep in. Sound - I enjoy listening to both. The device I used is my MacBook Pro streaming AptX to the Sennheiser’s and AAC to the Bose. The Sennheiser’s is the more bass heavy, richer and warmer sounding of the two. The Bose is very balanced and neutral to my ears. Very high levels of clarity and detail can be heard on both sets, but the Bose slightly edges the Sennheiser’s in immediate detail and clarity due to the more neutral frequency response. Soundstage is superior on the Sennheiser’s. Everything just has this multidimensional and spacious presentation. The music sounds more like a live performance as opposed to listening in a studio like on the Bose. The separation of the instruments within the music is slightly better on the Bose due to the more neutral frequency response allowing subtle nuances in the mix to be more distinct. This aides in the ability to replicate a more convincing sense of space between the sounds in which the Bose excels over the Sennheiser in this regard. The Sennheiser’s bass can sometimes come off a bit too boomy and mask the subtle nuances in the mix. But this is rare and it’s quite a feat despite the amount of bass emphasis here. It’s a healthy bass boost but it is centered in the sub-bass which mitigates bass bleed into the midrange. The Sony WH1000Xm3 in comparison has a bass boost mostly in the upper and mid bass which blooms over into the mids and makes them sound boomy overall. Overall the Sennheiser is a warm and rich sounding headphone with great levels of clarity and detail. The Bose is a balanced and neutral sounding headphone with a slightly favoritism towards the warm side of the spectrum and excellent levels of detail and clarity. The Sennheiser’s get louder than the Bose and don’t distort at max volume which is a plus if you like to listen at those volumes. The Bose at max volume can distort on some tracks. I personally listen to at most 80% so max volume performance isn’t important to me. Also, no, I don’t believe in burn-in (If you’re getting ready to say I didn’t have the Sennheiser’s long enough). I’ve listened to brand new headphones and a highly used one of the same model and they sound and measure the exact same. Conclusion - The Sennheiser’s have a special spot in my collection even though It performs worse overall in ANC performance, isn’t as comfortable to my head, has a worse overall battery performance, looks elegant but a bit uglier in my opinion than the streamlined Bose, doesn’t perform as well for calls, has less overall controllability from the headphone than the Bose, and it’s bulkier to carry around due to the much larger case that provides less protection than the Bose. Why? Because despite all that it still does the essentials required from a modern day 2019 pair of ANC wireless headphones all while packing the one of, if not the best sound experience in this category to my ears. It's a really close call between it and the Bose. Great job Sennheiser. You managed to incorporate a better microphone for voice pickup and 2 device Bluetooth connectivity (something the Sony WH1000Xm3 couldn’t do), decent, controllable ANC with ambient modes and good comfort alongside your signature sound. Color me impressed!
