Customer Ratings & Reviews

Best headphones i ever had im using them for pretty much music and when i go to the gym, noise canceling is amazing too you cant almost hear anything coming from outside loud noise, battery life i ran them until none was left before charge lasted me about 64 hours there is also an app if you know how to play with the audio to get the best sounds for whatever you into you can make profiles there. I highly recommend these if you into music, movies, even gaming if you get them to work the way you want them.

For a wireless headphone, the quality with the USB dongle attached is as close to a wired headphone as it could. Wore it on a 12 hour flight for the entire flight, extremely comfortable with long battery life

Excellent value for the money! Offers exceptional detail, dynamics, and a neutral, natural sound that competes with wired headphones. Build quality feels less premium than the competition (ex. Apple)

These are by far the best headphones I have ever used. The sound is so natural and realistic, it engulfs you in whatever you are listening too. Treble, bass, highs, mids, lows.. all incredibly accurate. Only thing I wish it had was aptX lossless via Bluetooth.

This sound really good compare to AirpodMax I can finally listen to hi res quality throgh BTD700 dongle that come with this headphones.

Great audio, fine ANC, great audio, good comfort fantastic bluetooth connection with the dongle

sounds good out of the box, but amazing when you use the parametric EQ. lots of hi-res connectivity options. very nice

This is a long review, so let me give you the TLDR up front. You buy Sennheiser for sound quality, not noise cancellation, “look at me” design, or features such as spatial audio. Sennheiser is all about the sound, and the HDB 630 delivers that like few other wireless headsets, and none close to this price point comes close. Now on to the review proper. When you open the box you’ll see nothing but a welcome sheet and a hard-shell case. The hard-shell case contains the headphones, audio and USB cables, an airplane adapter, and a Sennheiser BDS 700 Bluetooth dongle. While the earcups flatten for storage, they do not fold up. This makes the carrying case somewhat large but manageable. The product design is simple. Available only in matte black with matte silver accents, the product is devoid of decoration save a stylized Sennheiser “S” on each side of the headband. It is very Germanic looking, sometimes referred to as the “Teutonic coal bin” school of design. But in a world of headphones in bright metallic colors and overwrought design cues meant only to stand out, this subtlety sends the message that these cans are all about the sound. Personally, I prefer this simple design. The band and ear cups are made of memory foam covered in imitation leather. They are all well-padded, and I found them comfortable and easy to wear for long periods of time. The ear cups fit tightly around my ears, forming a reasonable noise-blocking seal. The folks at Sennheiser have decided that this iteration of its noise-cancelling headphones belong in their HD (audiophile) line rather than their Momentum (high-end consumer) line. They certainly live up to this designation. Using the same size 42mm drivers as the Momentum 4, Sennheiser has tuned the HDB 630 to deliver sound worthy of the HD line. The soundstage is wide (meaning it sounds like the music is coming from the room rather than the small space of the headphone). It falls somewhere between the Momentum 4 (which I own) and the open-back HD 560 (which I also own). This wide soundstage is a remarkable achievement in a closed-back headphone. Let’s get the BDS 700 dongle discussion out of the way here. You may not realize it, but odds are your phone, tablet, or laptop does not support advanced lossless Bluetooth CODECs like aptX HD. If you plug in a high-quality set of headphones like this using a cord, then connect to your device’s Bluetooth, the drop-off in audio quality will be immediately noticeable. The BDS 700 dongle supports these advanced CODECs. It will plug into any USB-C port and deliver wireless sound that is indistinguishable from the wired version. Unless you are using certain high-end Android products, the difference between the sound delivered by your device’s Bluetooth and the BDS 700 will be immediately apparent. In order to use the BDS 700, you must pair the HDB 630 to it. This is simple enough – just put the headset into pairing mode and push the button on the end of the dongle and they will find each other. The dongle can then be plugged into any USB-C equipped device and your headset will work. (With a caveat on lost connections, below.) The default sound setting (called “neutral”) is very clear. Bass notes are distinctive, not blurred, and I could not get the low frequencies to distort at any volume setting. This allows other instruments that overlap to come through cleanly while presenting each drumbeat and bass line as clearly as it was recorded. Midrange sounds are solid and highs are sharp and present. Every note of every instrument and voice comes through clearly and distinctly. You’ll hear details in your music that you’ve never noticed before, and these details come together to present a truly beautiful representation of whatever music you’re listening to. I really can't emphasize enough just how much better these sound than any other wireless headphones I've heard. The default setting eschews the v-shaped sound (heavily emphasized bass and treble) of most commercial headsets in favor of a flat, neutral sound. While this sound was good, I found it a bit too clinical for long listening sessions. It needed a bit more bass, and female vocals sounded sharp to me. Fortunately, this is all very easy to change in the app. The app has a series of pre-set sound selections and the ability to customize using either a graphic or parametric equalizer. You’re almost certainly familiar with the former, but the latter warrants a quick explanation. The parametric equalizer lets you decide what frequencies you want to center your adjustments on (up to five control points). It then allows you to decide if this is a standard adjustment or if it sets what’s known as a Q-level, where everything between this and the next adjustment point is either maximized or minimized to that level. It takes some playing around with, but it’s worth the effort to explore and figure out what sounds best to you. Fortunately, the parametric equalizer offers an A/B switch. You can set a sound, make adjustments, then flip between them to see which one you want to keep. If all of this sounds like too much work, the graphic equalizer has a simple “which sounds better to you” guide where it will create customized settings for you. The app is also where you set the automatic noise cancellation settings. This is continuously variable from off to no outside sound. While not as good as the industry leaders in noise cancellation, it works more than well enough to block sounds around the house or on a plane (I fly a lot, so I always leave it set to max). There is also a wind reduction mode, which I would turn off it you fly as it actually enhances the sound of the jet engine. The ANC mode also seems to interfere with the microphones for calls, so you’ll want to set that to disable on calls (it’s all automated through the app.) Now we get to the quirky things. If you’re connected through the dongle, the app can’t see the headphones. They have to be connected through Bluetooth for the app to work. While you can theoretically do this on one device, I found the native Bluetooth on my iPhone wanted to take control of the device connection, which drastically reduced the sound quality. I ended up connecting my iPad using the Bluetooth and the dongle to the iPhone using the multi-device connection option. This allows me to play music from my iPhone while adjusting it on my iPad. When I want to listen on my iPad, I turn off the native iPad Bluetooth and plug in the dongle. It’s not an ideal setup, but it’s one that works. I also have had issues with dropped Bluetooth connections. Both my iPhone and iPad at some point told me that they could no longer access the HDB 630 and I would need to reconnect it. Even the Sennheiser dongle lost connection and had to be re-paired to the HDB 630. On the iPad, the Smart Control Plus app does not have save or return buttons to get back to the main screen. You have to kill the app (which saves your setting as a new preset) and come back into it. All of these except the dongle connection should be easily fixable through app or firmware upgrades, and my experience with the Momentum 4 has been that Sennheiser is good at correcting issues like these. I honestly don’t know if the app can be made to work directly through the BDS 700 dongle, so a workaround like I use may be permanent. Summary of this long review matches the TLDR above. You buy Sennheiser for the sound quality, not the noise cancellation, spatial audio features, or fancy packaging. And the HDB 630 delivers sound quality that I’ve not heard outside of high-end audiophile headsets, does so wirelessly, and at a cost far below anything else that sounds close to this good. If audio quality is your guidepost, these are simply unbeatable.

I find these headphones really well built despite not having any metals on the outside, I assume to keep the weight down. The materials feel very sturdy. I specifically like the metallic-looking finish of the frame and the subtle glittery finish on the black plastic. The sliding adjustment of the ear cups is a little loose for me, but they don’t shift around too much during use. The cushions are very well designed and don’t give any fatigue after a lot of hours, especially in my case where I wear glasses and have had to take breaks from headphones due to them pushing the frame against my head and ear. The top of them could use a little bit more cushioning, but they’re not uncomfortable. The audio quality is astonishing compared to many other headphones I’ve tried. The audio is heavily detailed in the mixing and locations of the sounds - it truly gives the feeling of being in the room with the artist. I find the headphones in general to be a bit heavy on the treble, but that may be in an effort to increase the clarity and not muddy it with bass. That being said, even with the “bass boost” option in the app, it still feels a bit low on the bass. Another impressive aspect is the range of non-distortion. Increasing the volume just enhances all the details that you’re able to hear without muddying any of the individual elements. It holds the sound together in a beautiful way. Listening to some music that I’ve listened to so much, literally hundreds of times, I was noticing new details that I had not noticed before. The clarity and audio sensation when on a wired connection or using the wireless USB-C dongle is simply outstanding. I used the dongle on my phone and compared it to standard Bluetooth. Being able to switch between the audio forms showed a CLEAR difference. The dongle allowed me to utilize the “lossless” higher bit rate streaming to enjoy audio at quality I have never heard before. I find these headphones really intuitive to use. As for the touch controls, I was a little skeptical as the play/pause action is only one tap, but I have had zero issues with the headphones not registering my touches as something else. The audio adjustment can actually go up and down multiple ticks depending on how far you swipe your finger, which I find to be a great feature - but this does take some practice to get right. As a preface: I am nitpicking here! The ANC is still very good. However, here are two complaints: first, I find that it doesn’t filter out much for higher frequency things compared to another pair I’ve used a lot, and the general strength of the ANC is not as strong. Second , I was trying them out with power tools that have a consistent sound to them. This sometimes seemed to confuse the ANC into just switching off and on for a few seconds while I was using a power tool. Positives: The above instance made me wonder if it was confusing the frequency for a voice and reducing the ANC so you can hear the voice, but I realized these headphones don’t seem to have that feature. Second, there isn’t any sound leakage, even when moving your head or singing along. The app is super easy to use. I genuinely like the design and EASY customizability. I’ve never had a crossfeed feature before to blend L/R audio, and I found myself really enjoying using it. I find the controls really intuitive to start with, but I love that there is the ability to customize the gestures and touch controls to do what you want in case there’s something that doesn’t work for you. The provided EQs are overall great, and I appreciate the variety! I also listen to a lot of classical and the classical EQ brought out a lot of great sound colors. Overall, this is a great choice for an audiophile or enthusiast, given that it gives you multiple options to experience higher quality audio and it clearly has the capacity to handle it. I could also see someone using these as studio headphones for mixing. If someone’s commuting on public transport, my only complaint is that the ANC isn’t as strong as I’d hope for the listener to get to hear the genuinely lovely sound quality.

Verdict: I had my heart set on a different pair of touch headphones… Those desires are gone, and more than met by the Sennheiser HDB 630. They are close to perfect: comfort, sound, quality, discretion, customization, and lots of features. Exceptional! Initial Impressions. The style is discreet and unassuming of a pair of $500 earphones. There is only one button and one connector on the headphones. They are a bit more bulky and heavy than my previous headphones. Unlike other headphones that collapse into a more space efficient geometry, these headphones take up more space in my backpack. The package includes the headphones, cables (3.5mm audio, USB-C), USB-C dongle, airplane adapter (so convenient!!) and a case to store everything. Critically important for headphones, they are wonderfully comfortable! Setup. Thank you very much for including a quick-start and stickers on the touch area of the headphones to get me started. I already had the app from having a pair of Sennheiser earbuds, but if you don’t, there is a QR code for easy app download. Pairing is standard through the app or directly from your phone’s Bluetooth settings. App. Some apps are meh… Some are good. This one is fantastic; it offers everything I look for in an app and significantly enhances the value and capabilities of the headphones. The anti-wind feature actually works well, eliminating distortions from breeze or gusts. I have not really used sound zones before, but I appreciate the existence of the feature to customize specific settings to locations. The parametric equalizer is a game-changer. Bass boost is a must have for me because of my preference for heavier bass. Sound. I didn’t know what I was missing until now… Have these spoiled me now?? Sound quality is simply exceptional. The neutral equalizer has forced me to reassess my typical preference for heavier bass and experiment with details, which I frankly didn’t know I was missing before… Allowing for a new experience in my listening. I still resort to Bass boost, but I think I am appreciating more how lows, mids, and highs come together. Passive sound reduction is excellent. Active Noise Cancellation works decently, and contributes to an immersive sound experience. Things I love: - Exceptional sound - Love, love, love the touch controls!! - Very impressive battery life, and convenient quick charge feature to get 7 hours in 10 min of charging if you are in a bind - Exquisite equalizer - Hear-through mode works well - Comfortable, even after hours - USB-C Dongle for low latency audio can also benefit gamers! - Discreet styling, and uncommon, something I really appreciate - The padding works well with my eye glasses - Auto on and off if a feature all headphones should have, well done! - A/B button to hear the original sound vs your equalizer - Great call sound quality, but most importantly with a microphone that picks up my voice well. This is not always the case, with people telling me in the past that I sound “far.” Things I don’t love: - ANC could be better at this price point, but I find the current ANC level acceptable given all the other strengths of these headphones - The ear cups swivel easily so you could end up putting them in a way that they are slightly off center on your head, and thus impacting sound. Overall, the Sennheiser HDB 630 are exceptional… in sound, in comfort, in features, in touch controls, and in the app quality and customization. If you are looking for the best sound possible and can afford the price of these headphones, they are well worth it.

These headphones are easily the best I have ever had for audio from any sound source, especially music on my MP3 player. The construction is absolutely first rate and is built with premium materials. It comes in a very nice case that even has pockets for the included accessories: charging cable, wired 3.5mm cable, dongle and an ‘in flight’ adapter. This latter accessory I had not seen included with a headset before. The ‘inflight’ adapter is a dual-prong plug for the airplane's jack on one end and a single 3.5mm stereo jack for your headphones on the other. Gone will be the days that I need one of the cheap headsets the airline gives you to listen to a movie. A giant tip of my cap to the Sennheiser folks for including this accessory and for an outstanding product.  All features from noise cancellation to battery hours to phone controls etc., are top notch and worked perfectly. The noise cancellation and the ‘transparency mode’ are very effective and these are important features for me since I sometimes listen to music while I work in my woodshop with various machines that make a lot of noise. I still hear the music nicely. The noise cancellation is adaptive (a very complicated technology) and really blocks out the unwanted distractions. You can of course adjust the sound to your preferences including the amount of noise cancellation. The app is very well designed and I would suggest you download and utilize the ‘Smart Control Plus’ app from Sennheiser since it does provide guidance on the controls and includes easy setup to get the sound customized for your needs. The sound you hear is very smooth from bass to midrange to treble. It is so lifelike that you may think the band is in your living room. The technology used in this headset is far superior to the lower priced units; and well worth the cost if you want the best possible sound. The earcups are so soft I listened for over 2 hours with no hint of discomfort. I wear glasses and the plush pads produced zero pressure from the headset like I have found on other units. No more headaches from extended headset wear.  I certainly can highly recommend this awesome headset for its quality, beautiful full sound and advanced technology 'everywhere you listen'.

The Sennheiser - HDB 630 Around-the-ear Bluetooth Wireless Headphones are my new favorite for enjoying high resolution music with a neutral yet detailed sound. The build quality feels solid, yet lightweight enough, super comfortable and the sound and microphone are crystal clear. Thanks to the multipoint connectivity and the included BTD-700 high-res aptX dongle, they paired quickly with both my laptop and my phone via bluetooth. They come with 4 mics and Active Noise-Canceling which will satisfy a variety of scenarios providing different ANC and transparency modes. There is no noticeable hissing sound when ANC is enabled, but I feel like my Sony XM4’s have slightly better ANC even though they’re a couple of years old. The Sennheiser Smart Control App will allow you to fine-tune all settings and install firmware updates. The 5-band graphic EQ with standard presets may be more than enough for most, but Sennheiser offers additional fine-tuning with fully featured parametric EQ that allows you to tweak the sound to your liking and save the custom settings. Even out of the box, with the default “neutral” setting, they sound clear and precise with well defined mids and trebles, and just enough supporting bass. I would say if you’re mostly listening to hip-hop or rap music, these may not boom enough for you, but if you’re listening to classical music, jazz, classic rock, new age, you will love the detailed sound stage these headphones offer. Sennheiser went above and beyond the competition and included a BTD 700 USB-C Bluetooth transmitter in the box, which adds high resolution streaming to smartphones and tablets that don't natively support the higher-quality aptX HD codec. This small dongle lets you stream music at up to 24-bit/96kHz quality using the aptX Adaptive codec, which offers higher resolution and greater data transfer than the standard Bluetooth codec found on iPhones. You can also get the same lossless audio quality using them wired via USB-C or the 3.5mm audio cables included in the box. The touch controls and gestures take some learning and getting used to and could be a bit too sensitive. I wish they were more like the older Microsoft Surface 2 headphones that combine simple touch controls with smooth rotary dials. One cool feature is the auto-on/off feature when you pick them up and put them on, or power off when you take them off and set them down. The battery life is amazing, up to 60 hours with ANC off and an impressive 45 hours with ANC and high-res audio. The USB-C cable is about 5ft long which is very generous and comes in handy for connecting/charging other devices as well. A rigid carrying case with zipper is also included which helps keep them dust-free and provides room for all the cables and accessories for travel. Overall, these are very comfortable, well built headphones, with impeccable sound quality for high-res music listening for audiophiles and would recommend it to anyone who can afford it.

This is what a travel headset should have, a case with a place for everything you need that is decently slim and can fit nicely in a backpack. The headset is comfortable, the pads are just big enough to fit over my ears, so my ears don’t get bothered and the material is comfortable, the material on the top is extremely comfortable to touch and has some good cushioning. The overall built quality is top notch. In the box there is a USB C Bluetooth adapter, it is not paired with the headphones out of the box but works great. I like the fact that I have the option to have it as I might want to use it with my laptop, work laptop, tablet, kids tablet, or a random computer. There is the weird adapter for airplanes if you want to use that, it can be nice if the plan happens to have a movie you want to watch on their screen. I don’t love the Aux connector on the headphone, I really wish it was a full Aux size, but the cable comes with it and the case makes it easy to keep track of so it’s not the biggest deal in the world. Speaking of things I don’t love the touch controls, now I am not a fan of any touch controls so take what I say with a grain of salt. I mess with my headphones too much and every time I do I mess something up. One time I was talking and somehow, I muted my call but couldn’t find my phone (Bluetooth range is excellent). In the app you have the ability to disable the controls which I did and they have been exactly what I want ever since I did that. The controls are cool and fun but just don’t work for me. Though the one disadvantage to this is I need to open the app now to control the ANC, which works extremely well and doesn’t buzz my head at all. Now to the Audio… these sound awesome, they support lossless audio over Bluetooth. Between the noise cancellation and the wonderful bass and the overall clarity these can really let you just tune out the world. And of course you can turn on transparency if you can’t tune out the world for whatever reason such as kids. Pros: Sound great USB C Dongle Aux backup Travel Case Airline adapter USB C Charging ANC is awesome Cons: 2.5mm aux on headphones side Touch controls are sensitive

This is a really good headset. It's comfortable, feels sturdy, and it sounds great. The included hard case is not just sturdy enough that I'm not too worried about my headphones getting banged up, but it also has neat little slots for everything so none of the additional components are rattling about loose - USB cable, 3.5mm aux cable, airplane adapter, instruction manual, and hi-fi USB wireless adapter. The headset seems to be aware of when it's taken out of the case, and is often ready for use without me having to turn it on. The sound quality is great. There's plenty of detail, even at low volumes; the range seems pretty good; and this headset is capable of playing back decently heavy bass without muddying the rest of the audio. Currently, I tend to use it where it's paired to my phone over Bluetooth and my computer via the hi-fi USB wireless adapter (the manual calls it a BTD 700). I don't tend to listen to FLACs or anything on my phone, so this setup works best for me. You can also just use the headset over a USB C cable - it seems pretty plug-and-play as well, at least on Windows 11. As far as the user interface goes, there are a bunch of touch controls and things. I've never really cared for those and hate having to remember patterns, so I am really glad you can also do everything from the app. Interestingly, you can also disable certain controls from the app - I've never seen this before, but I am a huge fan of it since I often will wear my headset in bed when I can't sleep and find it really easy to accidentally trigger commands on headsets I'm wearing. Honestly, I think the only complaint I have about this headset is that I really would have preferred the pairing button be separate from the power button. I really like this headset, and I'd absolutely recommend it if you're looking for a headset to listen to music with.

Simply put, these headphones are incredible!!! I've read about Sennheiser headphones and knew they have a good reputation but I've never used any before these. My first words after putting them on for the first time were "Oh my God". I see why these are in this price point and honestly they sound like they should cost more. I'll start with the packaging they come in. Outstanding to say the least. I've a couple of other high end brand head phones before but Sennheiser takes it up to another higher level. There is no squeaking sounds from the moving parts and it feels like this set is designed to last a good long time. Fit on my head is rather comfortable and not tight feeling what so ever. The cushions for the head phones is soft and plush feeling. An added bonus is they don't feel at all like overheating while wearing them. The active noise canceling works perfectly. Where these headphones really shine is in the sound quality. Connecting via bluetooth the sound produced by these cans has absolutely no distortion and sound as if they have as near perfect sound that my ears detect. I am a bit of an audio snob and the sound produced by these a darn near perfect. Battery life is decent with no complaints. Another added bonus is they are not heavy on the my head. The included carry case is nice and provided an excellent method of protection when they are traveling with me in my backpack. Overall these headphones by Sennheiser are about as close to perfection to me.

I have been using the Sennheiser HDB630 Wireless Headphones for quite some time, and my overall experience has been excellent. They come across as a premium product right out of the box due to their lightweight nature and how they fit comfortably on your head during long listening sessions. The ear cups fit comfortably on the ears, and the leatherette headband is a nice touch. Where these headphones excel the most is in their sound quality. The sound is generally neutral in terms of tuning. Mids and highs are clear and have a wide sound stage. Vocals and acoustic tracks sound natural and well separated. While the parametric EQ is an interesting feature for those that love to customize their sound, it may be overkill for the average user. The crossfeed feature is a nice little touch for certain older recordings, creating a more natural sound. I haven't had any issues with the connectivity on the HDB630. I have found that using the aptX HD technology with the included BTD700 dongle, I've been able to get some cleaner wireless audio than I would normally get through standard Bluetooth. The active noise cancelling (ANC) feature on these headphones is satisfactory; in my opinion, not the most powerful compared to other leading brands in this category, but it does eliminate low-frequency background noise without compromising audio quality. As for the transparency feature on these headphones, it works great. Another excellent feature of the HDB630 is the battery life. I have been able to use the HDB630 for multiple days on a single charge; the fast charge feature is definitely a bonus. These headphones are not the cheapest on the market, but if you're looking for a headphone that provides great sound quality, customisation, and comfort, these headphones deserve serious consideration.

The HDB 630 bears a pretty conservative look that's pretty similar to Sennheiser's Momentum 4. They appear to be constructed out of plastic but they seem high quality. While worn, I never heard any creaking from it like some other plastic headphones I've worn. The cushioning on both the ear cups and the headband are plush, while the faux leather material feels soft and gentle on the skin. They feel comfortable for me, although with long sessions they can get uncomfortable from my sweaty ears. The ear cups can swivel in both directions, which is the first I've seen, for me personally, with the headphones I've used. I've found this very convenient because the right ear cup houses touch controls. With the ability to swivel in either direction, I can have the touch control side of the ear cups flipped away from my body to prevent accidental inputs, something that commonly happens with other touch control headphones I've used. The decision to go with touch controls is unfortunate because, like all the other headphones with touch controls, it's prone to accidental input. One time while wearing them outside in the cold wind after it rained, the HDB 630's touch controls wildly made adjustments on its own and I wasn't sure what. Whenever any touch input is registered it makes a beep sound (it sounds like the sound in Pong when a ball is it). I'd later find out from checking the app that the level of ANC was modified. Adjusting the ANC is done with a pinch gesture. Pinch in to increase ANC level. Pinch out to lower ANC level and allow more transparency (hearing your surroundings). Double tapping the right ear cup toggles between 100% ANC and 100% transparency. There's an anti-wind option in the app, which is absolutely necessary to block out wind noise, but when turned on, it decreases its effectiveness to noise cancel other sounds. When it comes to connections, the HDB 630 shines. You can connect it wirelessly via Bluetooth, or the included USB-C BTD 700 dongle (which can be purchased separately). You can also connect it wired via the traditional 3.5mm audio jack, or via USB-C audio. Something to keep in mind about USB-C audio is that connecting it this will have it drawing power from your device to charge the headphones also. The included BTD 700 does not come with a USB-C to USB-A adapter like the standalone version that's sold separately, so you'll only be able to use the dongle with USB-C devices out of the box. With the BTD 700, you'd be able to listen to your device wirelessly using the higher res codec, AptX Adaptive when your device doesn't natively support the high res AptX codecs. Double-pressing the button on the dongle switches it to low latency mode, which will help if you experience audio/video lag with the headphones. The dongle also works with other headphones as well. While it's convenient to have, I also can't help but think that we're paying the price, literally, for that dongle to be included with the HDB 630. That's $60 tacked on for something that not all users may use or appreciate. One of the reasons why the HDB 630's target audience is the audiophile. The sound signature of the HDB 630 sounds like wired Sennheiser headphones. They have a very neutral sound which could disappoint some users who've become accustomed to the warmer sounds from some of the other popular wireless headphones out there. But for audiophiles, that's the best setup to EQ with. And the main selling point is its parametric EQ. For those not as advanced to utilize the parametric EQ, the HDB 630 also has the traditional graphic EQ of which it has 5 bands (50, 250, 800, 3k, 8k). I think the best genre of music with the HDB 630 is probably classical for its clarity. With hip hop, the bass is so clean and doesn't muddy the vocals. But you won't get bass that really kicks like you would on some of the more general consumer-friendly headphones. Kendrick Lamar's Backseat Freestyle still thumps on the HDB 630 but you won't get that fun strong thumping from it. If you're a fan of exaggerated bass, you'll come away disappointed. But if you want accurate sound, the HDB 630 sound like a dream. Battery life on the HDB 630 is also a dream. I've had trouble draining the battery to get an accurate test of the battery life simply because it just lasts so long and I've been tempted to use it for just normal use. Sennheiser claims a 60 hour battery life, and I feel inclined to believe them. I've gone as long as 2 straight days of non-stop audio with the battery level at 100 (out of 150) on my Samsung Galaxy Tab S10 Ultra with battery life left to spare, so that itself was 48 hours. Recharging the HDB 630 from 0% to 100% takes 90 minutes. There is no way to access your digital assistant from the HDB 630 itself, so you'd have to access it directly from your device. As far as features go, it has on-head detection to automatically pause music, calls, or put the headphones into power saving mode when they aren't worn after a period of time. But nothing else. The microphone quality is average. I've been able to make calls comfortably, and listeners on the other side had no problem hearing me. But the microphone audio still sounds subpar. Add to the fact that the ANC isn't the best, which makes calls and microphone recordings pretty bad in a noisy environment. While using the microphone, the audio that's playing also gets degraded into what sounds like monaural audio, which is annoying. The ANC is pretty good for most everyday use cases, but when stacked against its competition, it's not the best. It doesn't block chatter as well other headphones I've used. But it will block out passing cars, especially with music playing. Car honking will pierce right through and can be heard. I guess it struggles with higher frequency sounds. Pros: -Sound quality -Parametric EQ -Connection options -Ear cups swivel in both directions -Includes bluetooth dongle to make devices support high-res AptX codecs when they normally don't Cons: -Lacks features -Audio quality degrades when microphone is in use For the bass loving listeners, I wouldn't sell the HDB 630 short, because the bass is clearly present with them and they sound pleasantly clean. I'd recommend trying them at a store to see if it's to your liking. Because everything else about the HDB 630 sounds amazing out of the box with its neutral sound signature.

I really like my Sennheiser HDB 630 headphones. In the past when shopping for headphones, I tended to purchase ones that I wouldn’t feel bad about losing. I opted for the best listening quality I could find for less than a hundred bucks. However, like most people who have attended a few too many concerts and sporting events without any regard for hearing protection, I had started noticing slight hearing loss. This became especially noticeable when I recently started studying Spanish and was unable to distinguish certain consonants when listening to Spanish narration. My cheaper noise-cancelling headphones were no longer cutting it. I began researching Sennheiser headphones because I was impressed by some Sennheisers I used for audio and video editing at my previous job. For me, the Sennheiser HDB 630 headphones checked all the boxes. The sound quality is excellent for podcasts and music. The noise-cancelling works quite well, even outside in the wind. They are lightweight and very comfortable. The earpieces have just the right amount of padding. They cover the ears completely while remaining comfortable when wearing glasses or sunglasses. The headband is well padded and stays in place. The controls on headphones are easy to use. The user-friendly app includes an equalizer that allows you to create and save your own filters. The headphones hold a charge for several days—longer than any other headphones I own. They come with a sturdy, fabric-covered case that has a mesh pocket and elastic straps for the included cords and adapters. For me, these headphones have been a game changer.

The Sennheiser HDB 630 is close to if not at the top of my all time favorite headphones. Firstly they look and feel great. I have a large head and these easily fit with room to spare. They are super comfortable for long sessions. At first I had planned on just using these to play music from my phone. But after hearing them I decided to connect them as my main audio for all my TVs output. That's apps like Netflix and YouTube, as well as all my gaming consoles. The High res audio is amazing! There is perfect separation for locating things in games. The audio and bass is tight. I mean that it's not that overblown rattling bass. Perfect accurate bass, miss, and highs. The adaptive noise cancelation is the best I've heard by far. It's almost too good. Drowns out all but the loudest ambient noise. It has a claimed max battery life of 60 hours, but I've never tested that. However after a full days use it still has plenty to go another full day easily. I went from just wanting these for phone audio on walks to using them for basically everything. Sennheiser knows their stuff. Super high recommendation!

I enjoy how much thought Sennheiser put into the carrying case that comes with these headphones. The case is sturdy, but not bulky. Every cable and adapter is positioned perfectly within the case to not come in contact with the other components. There’s an elegant beauty to the curved shape of the headphones, accentuated by the ear cups which have touch-sensitive controls but no visible markings. It’s a minimalists dream. There are three listening connections available: Bluetooth, wireless BTD 700 dongle, or USB-C connection. In Bluetooth mode, audio is muffled. It’s as if the music is playing on one end of a gym and I’m standing on the opposite end trying to make out what is being played. I have to crank the volume up several levels to feel like I’m hearing the source and the extra volume is not adding clarity or range, it’s now just louder muddled noise. The poor performance is disappointing because this is the most convenient mode and it’s one I don’t think I’ll ever use with these headphones. Moving beyond Bluetooth, the next audio quality bump comes from connecting the BTD 700 dongle to the source device. The headphones paired seamlessly with this dongle and audio quality lost the muffle. There’s only one problem - the USB-C dongle is not long enough to be plugged into an iPhone 17 Pro without taking off the iPhone’s case. I tried 4 different iPhone cases and none of them allow the BTD 700 to plug into the iPhone. The tip of the BTD 700 is too short. Sorry Sennheiser, but I’m not willing to pull my iPhone out of its case every time I want to listen to headphones. Strike 2 for wireless connectivity and quality audio. On the other hand the BTD 700 connected to my Sony Playstation 5 which is great. No luck on the Xbox Series X as the connector on the BTD 700 is USB-C. Controlling the volume, changing songs, pausing, etc is all handled from the right-ear piece. Simple gestures make for a smooth intuitive experience and I love being able to slide my finger up and down to control the volume instead of having to hunt for a physical button or dial. It’s a great thing that Apple finally joined Google on the USB-C port adoption allowing both the iPad and the iPhone to connect directly with the headphones. And oh my, that physical cable connection is a musical euphony. With a physical cable connection I am now enveloped in the music. I experimented with various audio formats including Dolby Atmos, Apple Spatial Audio, and just good old fashion audio books from Audible. In every sample the results are fantastic with the physical connection and in all cases drop to sub-par when falling back to bluetooth connection. Active Noise Cancellation (ANC) and Adaptive audio are two other features included with the headphones. I’m not a fan of adaptive audio on any headphones, but the ANC features did a nice job when I roamed around the home and neighborhood. I have not been able to take these on a flight to see how they perform, but I’m looking forward to testing the experience.
