[This review was collected as part of a promotion.] Cannot recommend this product. I have tried all the included fit adjustment pieces, but these buds do not stay inserted. I've owned corded Bose buds, but purchased the previous model of these cordless buds a few years ago and was very happy with them. They finally died & I bought this newer model a few weeks ago. They pop out when riding an exercise bike, or going up or down stairs!, or just moving my head too quickly. Not very useful unless I'm sitting in a chair

[This review was collected as part of a promotion.] These headphones are sleek, offer great sound, and they stay put during workouts! My only gripe is their connectivity. There are times that they work perfectly, but other times one or both side sputters with connectivity, produces static, and they can even be off sync with one side being ahead of the other. If they can fix the connectivity issues, these would be much better. Also, calls are a little tough to hear and also for the person on the other end of the line.

[This review was collected as part of a promotion.] I bought these for me and my partner since we both like running we have been in the hunt for some good earbuds that we can run in and will last us HOURSS, thankfully we found the perfect pair that not only sounds amazing also look amazing

[This review was collected as part of a promotion.] I've had many pairs of bose headphones, the open ear buds have been great! I've had tubes in my ear due to pressure and the open earbuds have been completely worth the money, not having to put buds in my sensitive ears, but still have the sound quality i've grown to expect from bose while living in hot humid florida i really cant complain, plenty of airflow obviously with the superior sound i've since bought a pair for my wife to enjoy too! if you can afford them, and are looking for buds i cant recommend them enough.

After using these earbuds for some weeks I'm happy to say they're great for working out and won't fall off your ears like others have. I've been using these at my job pretty much as earplugs and they've been more than comfortable when I use them for hours on end.

[This review was collected as part of a promotion.] I purchased these Bose open earbuds as a return to running from surgery gift for myself one week ago. I have never been so pleased with a set of earbuds in my entire running life, and I have owned Bose before. The fit for these ultra open earbuds is exceptional. Not only do they provide superior sound, being able to hear my surroundings is an outstanding safety feature. It does not even feel as I have anything in or on my ears. The earbuds do not move at all. I completed a 10K and the earbuds did not move. Holding telephone conversations using these earbuds is awesome as well.

[This review was collected as part of a promotion.] I bought these, about a month ago, have mixed feelings about them. They are very comfortable. Talking on phone, using earbuds, person I am talking to, always say having problems, understanding and hearing what I am saying.

[This review was collected as part of a promotion.] I purchased these for a Christmas present for myself. They are very comfortable and feel like wearing nothing. The microphones are placed on the inside so you have to adjust them sometimes for people to hear you.They also have great sound!

[This review was collected as part of a promotion.] The Bose Ultra Open Earbuds are of exceptional quality. They are incredibly lightweight and comfortable, allowing me to stay connected with my family and friends effortlessly. I can enjoy podcasts, music, or my favorite documentaries without interruption. Additionally, I no longer experience ear infections, thanks to these earbuds. The battery life is impressive and lasts a long time. The immersive audio is super cool!

[This review was collected as part of a promotion.] I bought last week and they are uncomfortable for me, my left one randomly goes quiet and it started to fall off. I double and triple checked the fit instructions and these just don't work like they should for $300. I will be taking them back, which is a bummer because I've always loved Bose products. The sound is ok when they both work. I really wanted these to work.
