[This review was collected as part of a promotion.] Absolutely love the product, especially for the gym and outdoor running. I love the additional awareness of my surroundings that the open earbuds offer. However, I've already had to return them twice. Bose has been great in the process, but I'm hoping this pair doesn't have the quality problems the previous two did.

[This review was collected as part of a promotion.] Battery is suck, two earbuds’ battery capacity are different, Right ear bud only can listen around 4 hours for one earbud, Left ear bud can listen around 5 hours, but sound quality is good , feel comfortable after 4 hours wear.

Great product, a little soft on the sound but expected because it is an open earbud. I think my Quite Comfort 2 sounds better, but hey, this works because it does not fall off my ears when moving around or exercising. Minor thing to point out, for those with large ear lobs, the hook is not long enough to completely grasp it. It's still secured, but not as comfortable. Does have some quirk on connecting to my phone sometimes - sometimes it doesn't connect, sometimes it loses connection. I turned off the voice prompt to see if it helps with that. Let's see. Turning off voice prompt does help with Quiet Comfort 2 earbuds for me. Wish Bose has fixed that already.

I bought one for me and one for a Christmas present. So far I am loving these open ultra earbuds. Besides the music, I am able to hear noises outside too. Very safe and comfortable. The earbuds stay safely attached to your ear and don’t fall off when I sprint during my walk. Battery life is long too so I don’t constantly have to recharge them. Excellent product.

[This review was collected as part of a promotion.] Sleek design and features. So glad to see that they are fairly compact rather than bulky given they are open earbuds. Easy to connect and wear, even my tech-adverse parents could handle. Love the sound quality without sacrificing and losing awareness of my surrounding, great for outdoors and physical activities. Also, as an add on I'm glad these are earbuds where you don’t look tacky wearing them through the office or when dressed formal.

I use earbuds every day, all day, and the most important tings that I have found needed for a good experience is fit, battery life and the ability for people to hear you clearly on phone calls. The Bose Ultra Open Earbuds fit the bill in a very satisfying way. I usually only wear 1 earbud so I can stay attuned to the outside world and this works very well. The cuff-like earpiece take a little bit getting used to in finding proper placement but they are not going to fall out & they are very comfortable. I mainly use mine for talking, listening to podcasts & audiobooks and they exceed previous earbuds in this regard. I wear one all day long into the evening with no ear fatigue or discomfort. The battery life is fantastic one will last me all day long & I've only re-charged the case once after 4 days. The app is clean and easy to understand and was easy to register and pair my earbuds with and has different modes you can choose from. I do notice my volume slider is louder on these but that's because they are not shoved down your ear canal. They are a little on the pricey side as are most Bose Products but Bose is a premium product and well worth it.. overall I give them a 9 out of 10 with the 1 point taken away because of the price.

[This review was collected as part of a promotion.] I bought these as a holiday present for myself in December after a friend raved about hers. They are so much more comfortable than expected and I don't have to worry about them popping out of my ear like in-ear buds do

[This review was collected as part of a promotion.] They are nice for working out, however there is not the best quality on a bose product I’d ever experienced. The mic is not good at all, when i am in a phone call, the people doesn’t hear me well. I don think it worth 300 USD

Nice earbuds. Only feature I would change is separate volume control on each earbud. The sound is excellent quality. I did have two incidents of cracking noise. It did go away after a minute. If it returns again I will contact Bose. Overall i am very happy with my purchase. The earbuds stay on my earbuds very well. I don’t have to worry about losing them.

[This review was collected as part of a promotion.] I love these earbuds. I don’t know what’s up with my ears but no regular ear buds will stay in my ears for any amount of time. The grip on these is firm but comfortable. I love being able to hear my surroundings and still enjoy amazing sound quality. At higher volumes, I can’t hear any normal sounds around me but any sudden loud sound is evident. They’re really nice for my runs. I can also use them while I’m running around the house getting tasks done. They’re loud enough that I can enjoy my podcasts in my kid-filled house, but I don’t have to pause when my kids come asking questions.
