I didn’t charge them out of the box, and when I put them in my ear it said “battery 100%”. I used them for a couple of times and received the same prompt every time. Then one day, they were just completely dead, no change or countdown to battery life, that’s why I gave 3 stars, which is really for the sound quality. Now I can’t rely on the battery status if I take them out anywhere without worrying about them dying. Sound quality good, function / features suspect.

I’ve had them for two weeks sound amazing. I am a professional bass player and playing in a band, I need to listen to songs in stream and performance videos so I can hear the full range of frequencies especially the low bass frequencies . These accomplish that and more plus sound, crisp and clear on all other frequencies.

I’ve never written a review that felt this personal. But the Bose Ultra Open Earbuds aren’t just a product — they’re a quiet revolution. I wear them while walking my dog, commuting, working, even cooking. The open-ear design means I stay connected to the world around me, yet the sound is so immersive it feels like the music is inside me. No pressure, no isolation — just pure, spacious audio that adapts to my life. They don’t fall out. They don’t block out life. They don’t ask me to choose between awareness and escape. They just… fit. Comfortably. Emotionally. Practically. If you’ve ever wanted earbuds that feel like they were designed for real people — not just tech specs — these are it. I’ve tried others. Nothing compares. I don’t say this lightly: if you’re reading this, you’ll buy them. And you’ll thank yourself every time you wear them.

I didn’t think OPEN EARBUDS would have such wonderful sound; but owning 5 BOSE products;one o which is the Radio/Cassette/CD player which as you can guess’ we’ve had for MANY YEARS and still use regularly. YES these are WONDERFUL with sound as good as any other earbuds; with the extra of being safer outdoors keeping you also aware of what’s golng on around you.

I bought these earbuds because the battery doesn't last very long on my other set of bose earbuds, however, the newer set seems to "auto off" on their own when I'm side sleeping and I can't find anywhere to turn this feature off. Otherwise I really enjoy Bose QCE and sound quality.

I just got these and they meet all the specifications I wanted and needed. They stay in place during my workouts and runs. The sound is crisp while allowing me to hear my surroundings. I owned the Bose sport earbuds for 3.5 years, I loved them, and they died a month ago. I bought the Bose qc earbuds and they sound great but they fall out all the time. These are perfect and the mic works great.

These contain all the quality and depth of sound I:be come to expect from Bose. I've tried multiple earbuds (wired and wireless and I continually had problems with keeping them in place if I as much as took a deep breath. These ultra earbuds stay in place with any activity I have taken on in the 2 months I've had them. I have had a couple of occasions where I had turned off the my music on my phone and didn't realize the earbuds were still on until someone asked me what I was listening to. They're so light and intrusive that I still had them on. As always, great job Bose!!

I bought this a couple of weeks ago, sound quality is awesome, it is not 100% comfortable, take some time to find the right fittings. I have an iPhone and sometimes is hard to have it paired with the phone, more like an iphone problem then the earbuds

I have purchased about 7 of the Ultra Open Earbuds. I am a fan. As a runner and hiker, I like the "open" concept for safety reasons. I have never liked things sticking out of my ears, like the AirPods. The design is a plus, plus. The earbuds have never fallen out while I am running, riding my bike or working out. I do wish 2 things: 1-that you do not have to use both ear buds at the same time. If you use only 1, you cannot close the case; 2 - the sound is better if you can somehow "tighten" the fit.

The Bose Quiet Comfort Earbuds are absolutely the Best Earbuds I have ever owned!!! I never used Earbuds too often because all the earbuds I've tried were uncomfortable to wear, But the Bose are so comfortable and the Sound Quality is so incredible, I rarely remove my Bose Earbuds!! I Love listening to music again and find it difficult to stop! I can wear my Bose for 8+ hours and I don't know that I have Earbuds in. The features of the Bose Earbuds with the Bose QCE App is incredible!! I have always been a big fan of Bose Products, so when I decided it was time for a set of High Quality Earbuds, I thought of Bose!! My car has a Bose Premium Sound System that absolutely Rocks, I have a Bose Wave Radio/CD and absolutely Love it, so the only choice for Earbuds, for me, was Bose!! The battery life is insane! I have not had to charge the case yet and everyday I put my Bose Earbuds in and they say Battery 100%. The Bass of the Bose QCE is Crazy!! It's tight, controlled and prominent, just the way I like Bass! The Mids and Highs, in my opinion, could not be more Perfect! I absolutely Love my Bose QCE Earbuds and could not be happier with my purchase or Bose Products! They are worth their weight in gold as far as I'm concerned and I Highly Recommend the Bose Quiet Comfort Earbuds to anyone wanting the very Best in earbuds.
