I bought this 3 weeks ago,very happy with the sound quality, however, it does not maintain the connection with my smart phone. When you spend this kind of money, it should be able to maintain a Bluetooth connection.

[This review was collected as part of a promotion.] I am so happy with the performance of this headphone. I know BOSE does a great job when it come to immersive sound but this was awesome

I've had these for about 6 months now and they're definitely the best all around ear buds I've bought yet. They fit my ears. No dealing with ear buds that don't fit the inside of my ears and of course they sound pretty good.

[This review was collected as part of a promotion.] Sent first pair back, TV sound came through with a lisp, and volume went up and down on its own! Took about 3 weeks to get another pair, they aren't much better! Save your money!

[This review was collected as part of a promotion.] I bought a white ultra sound bar and I am happy with my bar. It has incredible sound, it is fascinating.

Comfortable, the sound is great, using the app to fine tune the sound you want makes this even sweeter! Love my Bose QC headphones! I wore them for a 5 hour study session and they were so comfortable. Love them!!

[This review was collected as part of a promotion.] I bought this couple weeks ago and have been using for both music and work purposes. I am amazed by its sound quality and noice cancellation.

[This review was collected as part of a promotion.] great noise cancelation, super comfy and light, good sound quality and the auto switching bluetooth works great

[This review was collected as part of a promotion.] They're comfortable, the audio sound great, and the noise canceling and aware mode is so freaking good! Honestly wouldn't replace these headphones.

Happy with it, it's comfortable and the noise cancellation is good. Battery live is overall good. What I don't like is that multiple connections really loves my laptop and I hardly want to be connected to it.
