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

They are the most comfortable over the head headphones I've ever owned; and I've owned a lot. Sound quality is Bose.

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

Insane noise cancelling, fit and comfort. Feels like each instrument hits a different part of the ear.

I updated my headset from a QC35 to the QC45 last month! What a difference. Noise canceling much improved. Great sound quality.

Bought these for air travel and the noise reduction is phenomenal. With a good sound player and the app, the sound is concert level.

Great sound quality. Easy to connect. Decent battery life. Incomparably better than beats sound wise.

Not quite as much Bass as I would prefer, but comfortable and sound quality is super, love the volume control, noise cancelling, and appearance.

Purchase this 1 week ago. Very comfortable and sound ok. Wished it had paused when removed from head.

I bought this before my trip and it was a lifesaver! Love the noise cancelling and had no discomfort.
