Not what I really expected. Good quality, I just work in a noisy environment and the sound isn't loud enough. I know, open air, it's just a bit too much open air for me. I tried the quiet comforts first, and the phone calls were terrible. There is an open forum on the Bose platform about those. I returned them and, will be returning the open airs as well. I owned the Bose sports before and thought they were superior to these two. Sorry guys, trying the Sony XM5s next.

[This review was collected as part of a promotion.] I’ve had my ultra open earbuds now for about a month. I use them every day and I absolutely find them to be the most comfortable and stable earbuds I’ve ever owned. I’ve inadvertently walked into the shower twice because they are so comfortable you forget you’re wearing them. No problems and the sound is everything you would expect from Bose.

[This review was collected as part of a promotion.] Best earbuds ever definitely feel like I'm in the future with these. I can hear everything else around me and really good music all at the same time. Was the main reason why I bought these was I could talk to somebody and listen to music I don't have it too loud but

I am so impressed with these!! I was leary with purchasing such a high end product without first trying to test it. But....no regrets here!! I love that I can adjust the sound via my phone, I can get more bass and less of treble for music, and turn around and adjust for the podcasts I listen to.

I purchased these because I don't like traditional ear buds that are lodged in the ear canal. Typical Bose sound with rich base and clarity of sound. Perfect for physical activity, the stay securely in place. I am able to interact with the world around me and hold conversations in the open air mode. Full immersion a simple touch of the ear bud transitions to full immersion for a complete Bose sound experience. Easy placement and removal. Very comfortable, when I am not playing music I have forgotten that I even had them on.

[This review was collected as part of a promotion.] I have had these for a couple of weeks now and have been really impressed with the sound quality for an open earbud format. It doesn't sound hollow to me at all like other ones I've tried. I love using them while I'm doing chores and I can still hear if the kids need me. Outside, I've found I need to pick my volume wisely. Too low and I can't hear the music/podcast, too high and I can't hear my surroundings as well. Inside I haven't had that issue.

Love love love! The sound is perfect. I never would have believed the sound could be this awesome without having them stuck in my ear. I have small ears and could NEVER keep earbuds in, even the quiet comfort II’s would fall out if I was active (they were the best before these. There is ONLY one imperfection. They will randomly crackle and seem to cut out. If I pause what I’m listening to and hit play again they pick up. The don’t always cut out when they crackle, and the crackle is random and VERY infrequent, think listening 8 hours (at work) and crackle/pop (softly) 4-5 times for a second or two. Even with that, these are HANDS-DOWN the best earbuds around. *I never leave reviews*

I feel there should be a way to have the music funneled toward the ear canal. I barely hear my music. I won't return them because the concept is great. I was in a running event and I saw where a runner couldn't hear a runner shouting “passing left” so the slower runner should move to the right. The faster runner had to jump the curb because the slow runner couldn't hear what was going on because of the ear buds they had on. Wish you made a short extension piece, just to get the music closer to the ear canal without touching. Maybe about 1/8 coned adapter extension would be wonderful. I'm loosing to much of my music. Hope you can develop something. The coned thinking is to direct the music. Trust me it won't block surrounding sounds.

[This review was collected as part of a promotion.] I only had these for a month, but I have been searching for earbuds that have the great spund quality while still being open earbuds. So far I will put these on and sometimes forget they're on. Since they sit right outside my ear it doesn't bother them and lastly I think they look good. They are compact earbuds and are not bulky.

I entered this with Bose experience, but none with earbuds or in-ear devices. My ears are particularly difficult to fit in-ear, so I tried these. They provide the wonderful Bose sound you would expect, with full control available from the app. Direct control for volume, forward/back skip, mode change are somewhat clunky using the buttons on the device(s), but they do function as advertised. The Immersive audio is very nice, a welcome break from standard left-right stereo. The sound for me was quite full and rich, with good balance across the spectrum. Highs and lows sounded natural when using the flat EQ setting from the app, and playing with different settings was extremely easy. Flat works for me. The Auto-volume feature is a nice touch on an open air headset. The buds adjust volume depending on the noise level around you (to a point), which is very welcome. Yes, it is a drain on battery life, but nothing is free. Battery life is fairly accurate as posted in the specs. I achieved a but more, so quite good overall. I am unable to achieve the volume level I prefer, but I will blame this on my difficult ear fitting. I do wish they could be louder for me, but probably will be sufficient for a person with normal ears. That said, they are quite comfortable, and I have at times forgotten I was wearing them.... ....which brings a caution..... You WILL forget you are wearing them in quiet times, and won't notice when one is missing.... until it bounces off the floor beneath you.... if you are that lucky. Be cautious. Another great product from Bose. Highly recommended.
