[This review was collected as part of a promotion.] I do enjoy the quality of these Bose buds. The controls always work as expected and the battery does last for a solid four hours in immersive while I'm at work. This sound comes in so crisp. I'm especially impressed with the reach of coverage when my phone is downstairs and i go from room to room upstairs with no interruption at all.

[This review was collected as part of a promotion.] Love these earbuds so much for listening while walking my dog or jogging on my own. The open concept allows me to listen to all of my surroundings which was important to me for safety whether on sidewalks or on nature trails. They are very comfortable and stay much cleaner than in the ear inserts that can get coated in ear wax or push wax deeper into your ear (I say that as an Audiologist that works in hearing health)! Overall, I am thrilled with these headphones!

[This review was collected as part of a promotion.] I bought these several months ago, and have used them heavily and mostly while running. The sound is stunning, especially from an open earbud design, but my favorite part is the fit: I find it difficult to find earbuds that fit well. Once the speaker is in your ear, if you slide the other 'side' into place wherever works for you, they will be secure. It's also very odd but great to hear conversations and important things going on around you even with volume turned up to a reasonable listening level. I would definitely buy these again.

[This review was collected as part of a promotion.] I have the earbuds now for about three years And I am really satisfied with how it prefers especially when I need to isolate myself from the busy world and when you're right to even write an airplane I used it for like two flights now and it really does reduce the sound from the plane and makes you Be on the plane but not on the plane and that's how powerful the The Isolation of the sound is from the product and I really love the The earbuds it doesn't hurt even if it's on your in your ear for a long period of time and sometimes you forget that you have it yes really really satisfied.

[This review was collected as part of a promotion.] I’ve been a Bose believer for quite a few years. I’ve tried other headphones/earbuds but I always gravitate back to Bose because of the clarity and their different sound modes. Now with the new immersion mode you feel like you’re inside the music as you listen. I’ve always felt that Bose is on the cutting edge of listening enjoyment…and this is just one more step on their journey!

[This review was collected as part of a promotion.] I could not find wireless earbuds that fit and stayed in my small ears until I found these Ultra Open Earbuds. They have that amazing Bose sound and I like that I can still hear what's going on around me. They are comfortable and don't fall out, and stay charged a long time so I know they'll always be ready even if I haven't used them in a while. I highly recommend!

[This review was collected as part of a promotion.] When you have these earbuds placed correctly in your ears, the sound is amazing! But, it doesn’t stay in place as you’re moving about so it does require adjustments. The sound is really what tells you if it’s correctly placed or not. This is my third set of earbuds. Unfortunately my prior two failed almost a year in of using them. They would stop syncing and only one earbud would work and charge. Thankfully I was still under warranty each time this happened.

Son vraiment incroyable mais manque cruellement de Bass Les premiers jours il faut s'habituer à placer correctement les écouteurs mais par la suite on s'y fait Les boutons sont très rapidement pris en main L'application est toujours aussi fluide La batterie tient très longtemps et le style est extra

[This review was collected as part of a promotion.] Love these for the comfort. More comfortable than any pair of earbuds I've ever owned. Sound quality is the trade off. I have to jack up the volume a little because of the open design, but it perfect for listening to music when I still need to hear the world around me.

I really like these earbuds because they sound so nice and I love that they have good noise cancellation, and the battery life is genuinely insane. I've had these for 3 MONTHS and they've been sitting at 90-100% at all times. I actually never charge these earbuds for more than five minutes at a time and they've been full battery since I got them in February. This is SO AMAZING and I love this about these earbuds so much. They are just so finicky and very, VERY annoying at times. I'll be using both earbuds and one of them will randomly turn off and not reconnect until I put both back in the charging case. They'll disconnect for no reason and won't connect with my phone at all until I plug the case into a charger. Why so specific? I have no idea! But the funniest thing? This only stopped happening so frequently once I uninstalled the app! (Which is an entirely different app made only for this specific product, because the other app that supports the other headphones and earbuds apparently can't support these earbuds?) For whatever reason having the app on your phone makes the earbuds disconnect whenever they feel like it. Genuinely this is the weirdest thing I've experienced with technology. Sometimes I still have connection issues but since I've uninstalled the app it's only once in a while there's an issue compared to every single day. My biggest issue is the fact that you cannot turn of the sensors that detect when the earbuds in your ear, so if you happen to want to put one back it just turns your music off entirely and you have to manually reopen your app to turn it back on. Apparently a different model of the Quiet Comfort earbuds have a setting to toggle it off, these ones just don't. This is SO annoying that I genuinely want to return these headphones at times because of it. You can put tape over the sensors, I guess, but I shouldn't have to put ugly tape on my earbuds so they function the way I want them to. If there was a button to toggle the senors off in the app I'd be happy, but apparently that's too difficult? Please don't get me wrong I use these earbuds everyday because I genuinely do like them and I spent my money on them, but I wish I knew how frustrating they would be before I bought them because I might have looked for other options. TLDR: if you don't enjoy technology that is finicky and annoying to operate or you just get frustrated easily, DO NOT GET THESE! Don't do it, you will not enjoy them. If you can look past minor connection issues and don't mind not having access to the app (it makes the earbuds turn off and disconnect randomly) I would definitely recommend these earbuds! The battery life on mine is crazy and they sound amazing
