Customer Ratings & Reviews

The heart rate and body temp monitors are pretty much spot on. They work extremely well. They tested out as being the same or close to what my watch reports. The Earbuds charge quite quickly. Wireless charging is also an option. Battery life is extremely good. The app is very well designed and is not overwhelming. Easy to find what you are looking for. The default ear cups are quite comfortable and a perfect fit for me. ANC (Active Noise Cancelling) is one of the better results I have ever had with earbuds. This was truly outstanding. All of the extras work very well. Passthrough audio worked fine. Controls are good and easy to follow. BUT... The key piece of earbuds is how they perform in their basic functions. Sound quality, mic quality, etc. For a name like Sennheiser, I was expecting top quality audio. The rest of the package was bonus if they were any good. Unfortunately these fell flat. Flat. That is the only way I can describe the sound quality, flat. Everything is flat. I have gone thru the Sound Check, messed with the Equalized, change Noise Control settings. Nothing makes the sound pop. Bass boost is not good, it flattens the rest of the audio further and does not enhance the bass. Turning this off made the sound less flat, but was still lacking badly. Beyond that, the mic when in a call is horrendous. Everyone I spoke with said the same thing, they hear themselves. That echo makes conversations uncomfortable. Not only is the audio on my side poor, they are hearing themselves which affects how they are communicating. The case is kind of odd also. It has this rubbery patch that goes from the back that covers the USB Type C port and around the bottom to the base of the lid. It is very flexible, and a piece that makes me feel safe in saying it will tear at some point and the lid will no longer be attached. A hinge would have been a much better design choice. I really was expecting better. I can't say I would recommend these. Hopefully I just got a bad set.

Struggle with earbuds staying in my ears, so bought those thinking these would be right for me. With the different size eartips and wings, fit was great and comfortable. The actual temperature and heart monitor was not something I bought them for, and was pleased that the app had an eco boost setting to turn that feature off and in turn extended the battery life. Sound was great. However, I did end up returning these because they made a soft clicking sounds whenever the wind reduction or ANC mode was on. It was not noticeable while playing music, but when I had music on pause it was bothersome. Tried reinstalling the app, and tried doing a factory reset but did not help. Surprising, changing the eartips from medium to small made a significant difference in reusing the clicking sound, although having the temperature and heart monitor on or off did not make any difference. After troubleshooting, I just could not get that clicking sound to stop.

Considering I have several headphones in here over the ear open ear, I decided to get these because of some of the functionality. The heart rate function and temperature is pretty cool but most of the time I don’t use it unless I’m going on a run outside I’m really hot and I’ll take my phone. it tends to drain the battery a bit but overall it’ll last for significantly all work out. I don’t know about a marathon. The sound quality is not going to be the greatest compared to some other headphones and I think they are relatively overpriced. The Sennheiser momentum fours sound much better and have more functionality however I use these specifically for the gym which the noise canceling is great, and I don’t have to turn the volume up as loud. Overall, I would say 4 1/2 stars and I do recommend them, but they are significantly overpriced. I think the price point of around 250 would be a value amount in the heart rate and temperature sensing is not necessary.

Fit well. Sound is great. They occasionally crackle for some reason, but sound quality is superb. I wear them all the time for lifting, yard, all sorts of stuff when it’s need to be active but want music or need to communicate.

Great buds for working out or just general use. Balanced sound with great bass not over powering the rest of the sound. ANC is very good and the heart rate and body feature are useful. I would highly recommend these buds.

Good headphones, great sound and ANC is solid for the gym. Really need to get the right earwing so that your ears dont hurt. Usually takes about 1.5 hrs for fatigue.

Sound was amazing, but just like everyone says, the build quality leaves much to be desired. I personally had issues with the add on wing tips as they did not stay in place, even when trying other sizes (I generally use small ear tips/wing tips). This would be fine if I weren’t trying to be active with them. Would still recommend for normal listening use.

They sounds pretty good. Worth buying if you get them on sale. I had to return mine because they had a short in them.

I own the Momentum 3's which I love. But I have problems getting them to fit in my left ear snuggly which made them awkward to use at the gym. The sport which has a higher fin fit perfectly with no movement at all. I went to the gym three times this week and didn't have to adjust them at all. So for the gym, it's the sports for everything else it's the 3's.

It's not a bad product at all in fact the sound is exceptional. However, depending on your type of ears you might find these somewhat uncomfortable. The biggest downfall to this product is the case which opens easily and stops charging the headset. As far as the temperature detection of your body, I thought it was interesting but I had no Real use for it.

Great Acquisition.. excellent sound, app is very intuitive.

The Momentum Sport are fitness focused earbuds. They fit well in my ears and include 3 different sizes of earfins to help them stay secure. The fins are a rubber material that can be changed out easily. They stay firmly in place for workouts, and are also dust and sweat resistant so I can also use them for mowing the yard. Sennheiser is known for its audiophile sound and for what they are, the sound quality here is excellent. I have been using them for listening to music as well as taking calls at work. I’ve seen some other reviews mention that they are bass heavy, but I don’t find that to be the case at all. Perhaps the latest firmware update has remedied that. Either way, the Smart Control app allows you to adjust the sound with an equalizer and a bass boost mode. The ANC works well enough to reduce most noises like fans, A/Cs, etc but you will still hear louder noises which could be an issue if you wanted to listen to a book on a plane. Out of the box they will need a firmware update so make sure you download the Sennheiser Smart Control app and let that happen. It takes about 20 minutes, but I was able to listen to music while they updated until they needed to restart which only took a few minutes. Battery life is good enough for a half day or so without sticking them back in the case. They do charge quickly and you should be able to get through a whole day without recharging the case. The case supports USB-C charging or wireless Qi, a welcome feature. However, I do not like that the case is so large. Even with the room needed to accommodate the fins there is a lot “dead space” inside the case. The hinge for the lid to the case is also made of rubber and seems flimsy. Closing the case is not satisfying, as the magnet is very weak and it doesn’t always close flush, meaning dust or water could easily get in. The buds feature both touch (physically touching the earbuds) and “tap” (touching your cheek) to control play/pause, next track, answer/end calls, and to toggle ANC/anti-wind/transparency options. All of these controls require at the least a double or triple tap/touch on either the left or right. The controls are customizable but only to a certain extent. There is no option to single touch or tap. I really don’t care for the tap controls, where you touch your face, they are either too sensitive where you will accidentally do things or not sensitive enough where you are tapping the side of your face continually and nothing happens. I’d rather just turn them off, but unfortunately, Sennheiser doesn't provide that option. You can only turn off the touch controls, or all controls entirely. You can lower or raise the volume by touching and holding on the left and right buds respectively. In addition, these buds also support monitoring your heart rate and temperature. I use an Apple Watch typically which does heart rate but not temperature, so this a pretty cool feature. The heart rate readings between the earbuds and my watch are very close if not always the same. If I had to guess, the Sennheisers are probably more accurate since they sit firmly in your ear, but I cannot confirm this. You can sync the buds with the Polar Flow app which allows you to track the heartrate and temperature data while exercising. The Flow app in turn can keep other apps up to date such as Apple Health, which is what I use. Pros: - Excellent Sennheiser Sound - ANC / Transparency Modes - Earfins are flexible, more comfortable than plastic - Qi Wireless Charging - Temperature and Heartrate Sensors - Dust and Sweat Resistant Cons: - Large Case with flimsy rubber hinge - Can’t turn off “Tap” controls. Overall, these are very good wireless earbuds with only a few minor annoyances. They have great sound quality, comfort, and feature advanced features for tracking vitals for active users. However, just a tip, if you do not need the fitness features you might look at Sennheiser’s True Wireless buds.

Sound quality not good and fit was a little bit of a discomfort.

awesome sound quality and you get body temp and heart rate, i use these for bike riding and other sports amazing sound quality

The controls are confusing. The earbuds kept turning on and off when I was holding them, and some of the controls didn't even work when I wanted them to, especially the volume control. These earbuds are overpriced, the sound is mediocre at best, and my old $80 Senheiser earbuds are way better than this. This product is disappointing Sennheiser should have done better

I mainly use ear bud type headphones for physical activity, including yard work and things like that. So one of the draws to the Momentum Sports for me was the fins that are for secure fit in your ears. I’ve had other buds with this sort of feature and I’m happy to say that these work great for my ears. I leaning forward, hiking over rough terrain, lifting weights did great. No movement. The controls take a little getting used to, with no single tap. So you have double and triple tap and hold. I guess that’s to prevent accidental taps when active but it is always nice to have maximum options. There is also customizations for that taps and hold so that also helps. You have active noise cancellation and transparency, not off option. There is a variation that cuts down on wind noise and so it’s like you have the ability to hear things around you but not hiss from wind. It works pretty well, and I will say the ANC is pretty effective for things like mowing the lawn but it’s not silent. I also think transparency is good, not great. For me it has the muffled sensation to some degree, but you do get a pretty effective pass through. Sound wise, I definitely get that Sennheiser richness, and I feel like the bass has been bumped up, which I think is more for the fact that these are semi open backed to eliminate body noise when playing in your ears, so I wouldn’t put these in the super bass category. The sound is balanced to be honest. I would say for sport centric earbuds these are definitely nice. The case is large but pocketable. The battery life is good for what these are. I would definitely recommend them if it’s for active applications. But there are better options sound wise if you are listening in other situations.

They do exactly what they need to do and the donut very well. Highly recommend these!

Wanted to love them but the product slowly failed. Went from clear audio, then speaker had a peak sound issue ( ear bud speaker would pop then no sound temporarily then return with paper bag noise) after chalking it up to a break in period i had to take them back. Great Fit tho. Just failed sound.

These are terrible I haven’t even had them a year and they are falling apart. The noise canceling is decent but the bass is just not enough. The right bud is falling apart and the left the sound is going out. I will never purchase these again, just a waste of money.

Great fit but uncomfortable after one hour. The volume is way too low for my liking.
