Sound driven performance | Signature sound Powered by Sennheiser TrueResponse transducer, a 7mm dynamic audio driver that delivers a high-end sound experience with full bass.

Review: Phenomenal Value - 10/10 on every dimension. Sound quality is spectacular. Very full, clear, rich, and balanced sound. Great for every kind of music. Volume is perfect. The rubber attachments make for a very comfortable fit. Its easy to forget yoyre wearing them. The interactivity is quite fun and useful. I never had ear buds that were so handy. The waterproofing is great. I regularly wear them under ear-muffs during outdoor work and they work great even when wet for hours. Also, they work great as an indoor phone headset. Can talk for hours on them without audio problems. Batteries last forever. Also, my first pair failed randomly back in 2023, and Sennheiser repaired them for no charge. Since the repair, theyve been working great (2+years). I've used these things for 3900+ hours at this point and they are still like new in every way. It's rare nowadays to buy something like this and have them work so well for so long. Truly a premium product. Worth every penny. Ty Sennheiser!
Review: Super pleased with my purchase! - Great sound quality, very comfortable, and the battery lasts a long time before needing a charge. These buds come with a variety of in ear nubs as well as what I'm calling "fins" that sit inside the loopy part of your ear. I ended up using the smallest nubs and 2nd smallest fins and they stay in my ears comfortably without falling out. Touch controls on either side are customizable through the app. Sadly, the case doesn't have wireless charging from what I understand. They seem to be pretty durable from the materials used. And as expected, Sennheiser did a fantastic job with the audio from this product, and I'd say they're well worth the money.

### ⭐ Very good when it works. Rest of the time it's garbage.
*by F***. on August 11, 2023*

I have only used the earbuds about a dozen or so times. Mostly for jogging which is 15-20 minutes. A couple of times for bicycling around for a few hours. THE GOOD They have an IP rating for water resistance. Great for working out and resisting a few rain drops. The sound quality is pretty good, especially the bass. They are comfortable in the ear for a somewhat extended period of time, but not all day. Eventually my ear gets tired and hurts from them. So under 2 hours of use is ideal. Your mileage may vary. THE MEDIOCRE These are not extremely loud when using outside in a busy street, such as walking, jogging, bicycling, or any outdoor activity with heavy vehicle traffic around. I'm sure they are perfect for hiking, skiing/snowboarding, mountain biking, or the like, where there is some quiet. THE BAD After a few uses, the left earbud has begun lowering the volume by itself after a few minutes of use, becoming inaudible, making only the right earbud produce proper sound level based on the volume level of the connected device. I can barely hear the left earbud. I have to go through the ritual of disabling all Bluetooth devices, manually restoring the earbuds to factory settings, re-paring them with each other, using the Sennheiser app to also perform a factory reset, putting them into the charging case to turn off, take them out of the charging case, reconnect them to device, sacrificing various animals and praying to some undead god beyond the cosmos, just get both earbuds working properly. And it only lasts for a few minutes, maybe 10-15, before it does it again. This is garbage. MY RECOMMENDATION If you have some money that wants to be liberated from your possession, buy these earbuds, use them a few times, and cherish each of those times it works. Then subsequently smash them with a hammer, because they will be more useful as broken pieces of plastic and electronic innards, then keeping it around, frustrating you to no end as to why the damn earbuds don't work properly.
