I bought a month ago and the right headphone stopped working. I still haven’t received my replacement headphones.

I often times forget I'm wearing them. Sound quality is great even though they aren't crammed into your ear hole.

The best earbuds I have ever owned!! Sound quality and they are so light you forget that you are wearing them!!

I’m not a fan of them at all, I own just about all Bose head sets and others products of Bose, I’m a long time customer. These ear plug have excellent sound however, it’s difficult to wear in my left ear, it’s discomforting in my left ear, it’s very discomforting, I gave them to my daughter who’s paying me installments! lol!

I have had a had time with headphones, buds, plugs, etc. I can't keep them in my ears for too long. I really enjoyed Samsung's Bud Pro (Live) when they were available, because they were not entering the ear. But Bose Ultra Open Earbuds are what appear to be a natural evolution in the tech! I love it. I don't have to take them off if someone is talking to me, I don't have fatigue of them in my ears (can have them on all day and wouldn't even notice) and the sound is good. The sound quality might not be on par with other products but what this tech does, its a market on its own! The sound quality is great - don't get me wrong but at higher volumes it does decrease a bit of quality. But this product is GAME CHANGING.

These earbuds fit the exact opposite use case of closed/noise canceling earbuds. Being able to go through all my daily tasks and activities with background music while still being able to hear everything around me is a breath of fresh air. The open-ear design really does make a difference since all other earbuds have some degree of passive noise cancellation so listening to music and hearing a friend's voice an all its clarity is a pretty cool experience. Sound quality is surprisingly very good. I thought having an open-ear design would hinder it's sound quality greatly, but it still sounds very good to me. I usually have these at a lower/medium volume so it's almost like a cafe setting of having music constantly in the background while I talk with friends or coworkers. Once you put these at a louder setting it does lose slightly lose it's privacy, but the details and fullness of the sound really comes through. The fit and comfort is a bit of a learned experience. Since it 'bands around' your ear rather than going in your ear, you really need to find a comfortable sweet spot. When these are resting all the way down on my ear against my earlobe then I'll start feeling discomfort fairly quickly, but if I move it up on the middle area of my ear then I can leave it there for hours. The comfort at this sweet spot is wonderful because combined with it's weightless feel, most of the time I forget it's there. I tried jogging and playing tennis with these on and it surprisingly stayed on. It took a moment to trust that they weren't going to fall out, but eventually I was able to relax and just enjoy my exercise listening to music and bantering my friends at the same time.

[This review was collected as part of a promotion.] These headphones are excellent, I use them daily, they are lightweight and sometimes I even forget that I am wearing them because of their light weight.

Like the fit. Barely know there on you ear. Great sound use them while cycling. Can hear the music and Garmin Radar beeping when cars approach from behind. Keeps me alert while riding on the roads.

I bought a few weeks ago. Use them for the first time on an airplane. And I could hear everything that was going on. The fitting is not correct. It hurts the back of my ear. I will be returning them

Feels great on ear. Seems a little bug-y as I get a crackling noise once and a while. Non immersion sounds better to me as during immersion bass seems to be lost a little. Overall it us ok, not stellar (yet).
