[This review was collected as part of a promotion.] Love the sound of my Bose QuietComfort Earbuds but the quality is definitely not as good as it used to be. I've been a Bose wearer for many years and this is the first time I've had so many returns. Even had to pay for some outside of warrantee.

[This review was collected as part of a promotion.] I’m so glad I got my headphones. The sound is amazing and the clarity of the music it makes me feel like I’m in a movie theater or a concert. Especially when using them on a call. That’s why I usually buy your brand because of the quality of the sound, it’s remarkable.

[This review was collected as part of a promotion.] These are my go to travel and running earbuds. They are easy to carry, effectively block out ambient noise, but can be set on aware mode for using when I’m out running. They pair well with all of my devices. I have had to update them a couple of times when they didn’t seem to be charging, but it is simple to do in the app.

[This review was collected as part of a promotion.] As far as sound goes, they are great with extended highs, deep bass that reverberates, and a really wide-open depth-field. They no longer work, but that was probably because I wore them out. I didn't not purchase a new pair because I switched to the QuietComfort Noise Canceling Headphones in order to keep from having to put the earbuds in my ear canals.

[This review was collected as part of a promotion.] I absolutely love my Bose QuietComfort Earbuds! So much rich tones and deep sounds coming from such small devices. They fit neatly into my ears and block out the everyday noises. It's like I'm immediately immersed into my own mini concert during my workouts and runs. It's truly amazing. I highly recommend!

[This review was collected as part of a promotion.] Awesome sounding buds. They have actually spoked me that I will only buy Bose products. The bass and treble balance are perfect. A must have for daily use. The quietness is amazing letting you listen to every note. No other product comes close to it for perfect quiet and comfort. 10 gold stars from my experience.

[This review was collected as part of a promotion.] I have been using Quiet Comfort for several years. I mostly use them when cutting grass. They cut out lawnmower noise without having to turn them too loud. I have used them on planes and when the family is watching tv. In my opinion there is nothing better.

[This review was collected as part of a promotion.] The sound quality is superior to any other earbuds I've ever tried. there are probably two things you can do to improve this. One is just generally update the app it's not user-friendly. It's not easy to scroll through options. The other is to create more variability in size of ear tips. I also have the ultra and they are excellent as well.

[This review was collected as part of a promotion.] I love how comfortable they are. They sit perfectly in my ears and I can wear them all day without feeling anything. Other earbuds keep slipping out but these stay in nice and firm. The sound is amazing and crisp. The noise canceling is a lifesaver in my noisy office

[This review was collected as part of a promotion.] I purchased these earbuds when they were first released. I couldn't be happier. They fit my ears really well and are very comfortable. The sound quality is great and according to people I speak with on the phone, the mic is really good too, with little to no audible background noise!
