[This review was collected as part of a promotion.] I bought these about 10 months ago. I’ve used them almost daily on my walks as well as runs. What an upgrade!I’ve had issues with earbuds - not comfy, falling out. No problems with my ultra open Bose. And the sound…wowza. Love! I have recommended these to everyone; gifted a pair to my daughter for her birthday. She, too, loves them.

Performance was unbelievably awful. Used these for a couple of weeks and it constantly struggled to pair with my phone and when it did only the left earbud would work. I’d leave the buds in the case to charge and it would automatically connect to my phone. Cherry on top of the cake, the sound quality was poor. Every person I spoke to mentioned how far away I sounded or they could barely hear me.So sad because in my experience, I’ve never had an issue with Bose over ear headphones but these earbuds are a completed dud.

[This review was collected as part of a promotion.] I brought these as a Christmas gift for my Daughter. She has very small ears and nothing fit her correctly. I decided to give these a try and I’m very glad I did. She loves them! The fit is very comfortable yet secure and she is very pleased with the sound quality as well. She told me she feels more confident and secure while walking as she can hear her surroundings to keep her alert.

[This review was collected as part of a promotion.] I’ve bought like 3 pairs of these I lost one one broke and I’m on another refurbished set today. The only problem I tend to have with these are that after a while they start to go all static for some reason not sure why but they are very expensive to keep buying more so this will probably be my last pair ever unless that issue gets resolved.

[This review was collected as part of a promotion.] This is my 10th or 11th Bose product and 5th Bose QC product I have purchased and have been using! When it comes to noise canceling headphones Bose headphones are the best! They are great for long distance air travel for long battery charge and quick case recharge. Also wearing them for longer periods of time is good and comfortable experience compared to any other brand. When I say any other brand I mean Sony, Apple, Harmon Kardon, Ausdom, Scull Candy, JBL, Bowers & Wilkins, Sennheiser etc. I own all of them! That’s right! I have a thing for headphones! That’s it!

[This review was collected as part of a promotion.] Bought these right after Christmas! Love them! All other earbuds fall out of my ears and after a while hurt my ears. These stay in place no matter what task you are doing! Would recommend these to my friends and family for sure!

These are my favorite for workouts and yard work. They’re fantastic because you get great sound while still staying aware of your surroundings. I can listen to music and still hear my wife if she calls me—something you don’t get with most headphones.

[This review was collected as part of a promotion.] I first hated them. It was so weird for me to pass from earbuds or headphones (all Bose) to those open earbuds. Now I just love them. This is a fantastic technology. I recommend them for sure with no hesitation!

[This review was collected as part of a promotion.] Great sound quality, excellent noise cancellation, and very comfortable to wear. The Bose QuietComfort Earbuds II fit securely, have strong bass, and block out noise impressively. Easy to use, solid battery life, and perfect for everyday use. Highly recommended.

[This review was collected as part of a promotion.] I purchased the Ultra Open Earbuds as a Christmas gift for myself. The set up was absurdly easy. The online product instructions are excellent. The buds are extremely comfortable, are secure while I'm walking and continually surprise with features that I did not know existed. For example, there will be a brief interruption to a book I'm listening to on Audible to announce the distance walked, the time taken or when I've closed an exercise ring on my app, then it effortlessly slips back to the exact place where the book interruption took place. More important, sound quality is excellent and the choice for complete noise cancellation or partial is quite helpful depending upon the environment (as in not always using complete noise cancellation while walking in a busy area).
