Got this as a Xmas present. I really enjoy the sense of quiet, in a crowded room, or where there is ambient noise.

Got these for Christmas and have been wearing them everyday, great for noice cancellation while I'm studying

I used them for the first time on a flight. Sound was good. I'll see how they perform as I use them more.

When it's windy outside terrible sound and cut out phone calls. They need to improve cups around ears.

Noise reduction is not as good as previous models. Bluetooth phone connection isn't clear. Other parties can't hear very well.

Have had the QC45s for about a month. Would be perfect if you could turn ANC off. Hopefully a future firmware update will add this feature.

I bought this a couple weeks ago , it works great , quiet mode , you only hear your music, video or talking to someone .

The ANC is perfect however the sound is lacking in the lower frequencies response. The bass isn't punchy but is very neutral

This item is the best I've ever had! It has amazing noise cancelation, great base, calls are heard well and are enjoyable

Extremely happy with this pair! I have had a few pairs of high quality headphones and these are at the top of the list.
