After two weeks of continuous use, I can confidently say that I can't imagine going without these headphones. They've seamlessly integrated into my daily routine, competing in usage frequency with my trusted QC45. They've unveiled a niche I didn't realize I was missing. Key Highlights: • Sound Quality: 5/5 • Ergonomics: 5/5 • Battery Life: 5/5 FYI: • No noise cancelling: These are OPEN BACK headphones, intentionally designed for ambient sound awareness. • Potential discomfort for upper lobe piercings. Pros: • Unmatched Comfort: Having previously experienced discomfort and pain with AirPods and other in-ear options after just 20-30 minutes of use, the Ultra Open design is a revelation. Unlike traditional in-ear options, these earbuds feel more like comfortable cuffs than intrusive buds. I can wear them for hours without discomfort. • Superb Sound: Among my collection of headphones, few rival the audio quality of these open-back earbuds. • Impressive Battery Life: Even with 4-5 hours of daily use over two weeks, I've only had to charge the case once, never interrupting my usage. • Secure Fit: Whether bouldering or running, these earbuds stay firmly in place, providing peace of mind during physical activities. Cons: • Occasional Sound Interruptions: Despite the immersive audio experience, there are sporadic cutouts, although the development team is actively addressing this. • Confusing Case Design: The case layout can be perplexing when storing the earbuds. • Initial Confusion with Earbud Orientation: It may take some trial and error to determine the correct way to wear the earbuds initially. • Challenges in Noisy Environments: In extremely loud environments, hearing music can be difficult, though the auto volume feature helps mitigate this issue.

I like the instant Bluetooth connection. However after the original Bluetooth setup with the Bose Quiet Comfort app the Apple iPhone IOS takes over and overrides the Bose app 50% of the time. Which means I cannot adjust any earbud settings through the Bose app.

Fun new design, very comfortable, stays on during workouts, sound quality is great however they’re not as loud as quiet comfort due to them being outside the ear canal. Plenty loud enough to hear fine while working out and it’s nice to be able to have a conversation etc while listening to music. Battery lasts significantly longer than previous models.

I have been using Bose products for more than a decade and am a fan of Bose. But the latest Bose Ultra open earbuds are not a great product. Sound of the product is pretty low when you are in a busy environment like gym or running. I will switch back to my Bose Ultra Earbuds

[This review was collected as part of a promotion.] My husband got these for me, for when I walk our dog on hot days. The sound is great. They are comfortable and lightweight. I am not afraid I am going to lose one when walking the dog or working out. Only downside was trying to connect them to my phone took a bit as it wouldn't recognize the new Bluetooth device.

[This review was collected as part of a promotion.] The good: very lightweight and comfortable, I can wear them longer than any other headphones I have (QCbuds and QC overear included). Sound quality is as you would expect from Bose - great. The bad: I live in NYC and thought these would be great to wear around so I can be aware of surroundings while listening to audio. This works for music, but I can't hear my podcasts clearly enough even with volume turned all the way up. NYC is loud, so this is probably only be a problem in very loud situations, but it was disappointing. Also, I have very sensitive skin and the backs of my ears have gotten irritated where they clip on. A pity bc they really are comfy, so hoping that calms down with time.

[This review was collected as part of a promotion.] I am very happy with the sound quality of the earbuds as well as the way they fit on your ear. They are comfortable as well as secure. They allow me to listen to audio as well as the environment around me. The buttons allow me to manipulate music as well as phone calls without having to pick up the phone. Overall a great product

[This review was collected as part of a promotion.] I was having issues with comfort and building up earwax with other earbuds. The Ultra Open Earbuds sit with comfort and don't hurt like buds that sit in your ear. Although it'd be cool to get some type of noise cancelation feature, I can live without it. They do however have a cool feature that can make music more immersive. Overall I really like these and am happy with my purchase!

This was my first time trying an open earbud device, and truthfully I wasn't sure what to expect or if I'd like them. Historically, I've only used over the ear headphones or more traditional in-earbuds. That said, I was pleasantly surprised by how much I enjoyed these! I did find many use cases where I preferred the open earbud design vs. traditional in earbud. However, I also did find multiple occasions where I wished these had a noise cancelling feature (i.e. environments with loud external auditory competition). I'll share some pros & cons below, but overall I'm really happy with these buds. For the price, I know it's not practical for everyone to have multiple pairs of expensive earbuds, but if feasible I think these are a great second pair. Without noise cancelling functionality, I don't think I could commit to these as my sole, primary earbuds. Pros: - You can't tell I'm wearing them (context: I have long, curly hair) - The audio is great even with the open ear concept - I LOVE that you can control the volume from the earbud - They are very comfortable to wear for a prolonged period (if not, you may have to adjust them; slight repositioning is the difference between my ears aching or not during prolonged wear) - These are GREAT for sports (I used them while skiing / running and loved how secure they were & I could still hear the environment) Cons: - They often get caught in my hair (while down) and/or get knocked off when I put my hair behind my ears - They aren't as easy to put in your ear one handed and take some adjusting to get the perfect fit - People standing next to you CAN hear your audio - Immersive audio sometimes has an echo when I'm listening to podcasts or talking on the phone - The open ear concept can get frustrating when you're often in environments with loud external audio competition (wish there was a way to block out noise if needed) All in all, no product is perfect and I would definitely recommend these to others.

[This review was collected as part of a promotion.] I got these to replace my air pod pros and man and I glad a did. These are hands down the best earbuds I’ve ever had! Not only do the sound amazing but they don’t fall out of my ears like the air pods do. 10/10
