Momentum Sport - Earbuds with Sport Sound Tuning and Adaptive ANC, Secure Fit, 24-Hour Battery Life, Fitness Tracker for Body, Graphite

These are the best TWS IEMs I’ve owned! I’ve owned so many down through the years. First, anyone with fit/comfort issues…you may need to purchase aftermarket tips. The included tips have various diameters to create a tight seal. The challenge is, like with many TWS IEMs, the included tips are shallow and angled. Depending on ear anatomy, and how far you push them in, the edge of the tip can rub/irritate your ear like the one review showed. I highly recommend going in Bloom Audio site and ordering the Baroque Stage ear tips! They fit these perfectly! They’ll be significantly more comfy, create a better seal, provide better clarity, bass, vocals, and sound stage! The only downside to doing this is that the heat rate sensor won’t work. I personally don’t care about the heart rate sensor as I have my watch and a separate wahoo arm band for this. I wanted these for music while cycling. When you add those tips and properly calibrate using the EQ within the amazing Sennheiser App…these are ridiculously good. The bass is rich and full…it scales well, so as you turn the volume up the bass becomes so thunderous it’s amazing. I do like treble, too, and while good…I wish they had slightly more sparkle up top. The ANC works great, and the transparency mode also excellent! You can also control the levels of those listening modes, too. The App is fully customizable and easy to use. It really gives you the best features to optimize the experience. Regarding the wings…just make sure you follow the instructions ands put them in properly if you are trying to change the size. Last but not least…the ability to control them by tapping your skin near your ear is genius ands it works well. When cycling, it can be tough using other IEMs…trying to precisely tap on the right spot of the face of the IEM…without causing it to shift, become loose in the ear or push it into the ear. With these…no issue at all. The skin tap near the ear works perfectly! You can adjust the sensitivity of this function. These sound better than $500 TWS IEMs that I own! Now, fingers crossed that these hold up over time. I’ve read some of the issues with connectivity. Perhaps they were being used with older phones? Also, if you use the highest quality sound codec, they note it can drop out. So changing that setting could make all the difference. These are a steal at this price…considering they were $329 when released.

It is shocking how bad these are for the price. For those unaware, Sennheiser sold their audio division back in 2022, as someone who was a big fan of their products I was wary that their quality might drop under new ownership, but I never imagined it would be as bad as this. Aside from the bass response, the audio quality of these headphones is on par with $35 skullcandy headphones you buy from an airport vending machine out of desperation because you forgot to pack something actually good. Seriously, these sound like you're holding earbuds an inch away from your head, not actively seated in your ear canal. They tout Active Noise Cancellation profiles as a product feature, I would ask what the point of these profiles are, considering they don't seem to even do anything. I tested these while riding my bike and the Wind Cancellation profile was non-existent, I have 10 year old regular wired IEMs that have nothing more than a good fit in the ear to overcome wind noise that perform better, and they were half the price of these. So how do you get past the fact that you can hear the wind more than the music? Turn the volume up, right? Not with these, the maximum volume is pitiful, good luck hearing anything you actually want to, but you'll sure be able to hear the overtuned treble, which will assuredly hurt your ears more than the poor fit. Speaking of hurting your ears, the bluetooth connection is abysmal, and is prone to actively crackle at a volume that makes it genuinely sound like the earbuds are attempting to electrocute your eardrums and cause permanent hearing loss. These come with wingtip attachments clearly designed to fit along a stripe in the design of the headphone, with a dash on the headphones you align a hole in the attachment with to make sure they're on perfectly, but they actively prevent you from clicking the headphones into place in the charging case unless you slightly misalign them out of the way. I was a big fan of Sennheiser for a long time, have had several of their products over the years, if this is indicative of where they are as a company, I will probably never buy from them again.

Sound quality is very good and the different ear fins make it easy to adjust the feel and fit pretty fine. low review because the right earbud just stopped charging properly after 3 months. Gets enough charge to turn on for a few minutes then shuts back off. tried cleaning connector pins and making sure the pins were actually making contact but no luck. also tried factory resetting the earbuds from the app but that didn't work either.

1st: wrong color delivered 2nd: sound cuts and crashes at max vol. On bassy songs 3rd: comfort is not the best but I'm willing to try a different unit to see the difference. Everything else works as intended. The temperature reader as well as the HR sensor are as accurate as my series 6 Apple Watch and any modern thermometer The polar app was a bit annoying to get into but seems to work fine. I couldn't workout due to the sound defect I believe I unfortunately got a defective unit so will get a replacement tomorrow so test the difference. Will keep y'all posted Edit: hey so I got the replacement the next day and it's better but I think this Sennheiser buds have a poor response to bass. Idk but somethingis wrong with the DSP here but they're usable. U can't go to loud with them tho'. Especially with supper Bassy song. I'm a lil disappointed that they are this poorly build internally but the HR sensor and how it works so seamlessly with the Polar app to track your work out. ANY WORKOUT!!! IT works so well that I sold my series 6 Apple watch after tracking my 2km night run. It was perfect. The data was layed up- very easy in the app compared to the one on the iPhone thats way too comber some with all the colors whereas as the pOlar flow app give you everything in an uniform manner. pLUS YOU GET YOUR TEMPERATURE READ TRHOUH UR EARBUDS!!! Just this take this review from 2 stars to 3 but not 4 cuz these miss where every earbuds should hit : SOUND but it's not too bad so I'll keep the replacement but will be keeping an eye on the warranty as I've heard a lot of bad things about Sennheiser earbuds on reDDIT

Fits well with my large ears (usually need a large or XL silicone tip to make isolation work). They are decently flush, do not sick out far. I appreciate the custom tip and wing sizes. I have not tried the Polar Watch Health Features that sync with this, but I can tell you that it is great to see Realtime heart rate and body temp (seems accurate when comparing with my other sensors) in the Sennheiser App. Because they fit snug, I do get a bit of ear fatigue but these are the only earbuds that stay in my ear with sports, eating, or moving. Noice Canceling is great, worked well on a pain. "Wind mode" seems to work like transparency mode on other earbuds. The sound... better than Pixel Buds Pro 2, possibly better than Bose... Nice highs and good balanced lows (not overpowering bass but there is an emphasis on base). First pair of earbuds to have the treble be sharp and precise, I love the sound. A bit expensive at full cost but if you can get on a deal, I would recommend them if you need noise canceling earbuds and have hard to fit (always fall out) type of ears.

Let me start out by saying that while other reviews say the ANC isn’t that good I really disagree. I’m not sure if they know this but these are semi-open by design and even still the ANC is really good. The reason they are semi-open is beacuse of safety and also beacuse it stops the dreaded foot drop effect when running. You know when you run and you hear each and every step as a thud in your ears? Well these have very little of that. If you’re a runner you know what I speak of. The default sound profile is good but if you don’t like it you can tune the buds to your liking in the sennheiser app. The app isn’t the best but it’s much better than allot of the competition out there. I use these with an Apple device so I don’t get to take advantage of the aptX codec but even with AAC it does sound really good. The anti-wind mode is really awesome for outdoor runs. It does a fantastic job at cancelling out wind noise. I honestly don’t even hear it when in this mode. I’d say transparency mode is about 80% of what Apple AirPods Pro 2 are. It’s very solid. My two biggest knocks on them are that the fins aren’t very comfortable and I think the heart rate and temp sensors are gimicky (I am not in the Polar ecosystem). After about an hour or use. There is some dull feeling in my ears and I use the smallest fins. Unlike the Beats sport buds which are one solid piece of rubber fin they put a slit in the fin which I think is for flexibility. What ends up happening is that they dig into your ears a bit. I hope they or someone makes after market fins that are a little more comfortable. Secondly, I have an Apple Watch Ultra and get my heart rate from it as connect it to my watch for music on my runs. I’m not sure if these will ever integrate into Apple health but the polar app really isn’t all that useful for someone not using a polar device. I use these mostly for running and I don’t see the value in the polar integration since I’m not in that ecosystem. If sennheiser were to fix the fins and make them a solid piece of rubber and possibly removed the heart rate and temp sensors and sold the buds for ~$60 less these would be the the most recommended sport buds. However with the beats sport buds a bit less you really have to see the value in the sound quality to get these. All in all as an audio enthusiast and outdoor fitness person I will highly recommend these. I think the sound quality and ability to customize the EQ is a great feature. The ANC, transparency, and anti-wind modes all deliver, and while I don’t find the find comfortable they buds always feel secure in my ears and I never worry about them falling out.

At this moment these are 5 stars for what I am looking for. I have had the MTW4’s for a few months now and have already needed replaced. Yes, annoying, I had to pay like 8 dollars to ship the old ones back and I got a new pair back. That’s main reason why I started looking for another pair of earbuds as I had started working out regularly as well. I wear the Momentum Sports for about an hour at a time with the medium fins and they fit my ears really well. I wouldn’t say they get uncomfortable while wearing them until I move or remove them and I can feel where they were pushing into my ear maybe? Overall I would say comfortability and fit is good to great. Sound quality is great just like the mtw4, just a bit less bass and a bit less volume, they are still loud enough that I never have to go past 80 or 90 percent volume. I had the green pair before the grey colored pair as I wasn’t as big into the green color and the matte finish made it difficult for me to grab or hold onto them, especially when dry. Just wanted to put it out there that sennheiser might have questionable quality control, the sound quality amongst all the other positives are too good for me to go to another brand.

As much as I love the Sennheiser brand overall, these earbuds failed in all aspects. The sound quality was okay, but the volume level was painfully low compared to other options. The noise canceling was okay. The fit was decent at first, but felt a little tight after a short workout. Still all these could have been forgiven if the most annoying issue wasn’t happening, which was a weird popping sound in the earbuds during music. I didn’t have the bass turned up that high, yet there was an obvious popping sound during playback. It came and went randomly, but it happened often enough where I just can’t use this realistically. If a Gen 2 of this product were to happen, please address these concerns.

We have owned these for over 6 months. My son uses them daily and they are still working great! He loves the sports features.

Broke within the first few weeks, weak volume with static in one ear. Customer service was a pain to deal with

Disappointing from Sennheiser. I love their DJing headphones but these fall short of quality. The sound crackles and is distorted and the heart rate monitor it's accurate at all. My previous Jabra sports were so much better. Sennheiser need to update their game as these are a total let down.
