Momentum Sport Earbuds with Fitness Tracker for Heart Rate and Body Temperature - Crystal-Clear Sound with Adaptive ANC, Secure Fit, 24-Hour Battery Life - Graphite

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

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.

Audífonos muy buenos el sonido es espectacular muy peculiar de la marca y para hacer todo tipo de deportes con las almohadillas y aletas de tu medida no se te caen

Awesome sounds and quality

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.
