The QC45 have solid noise cancellation, but they're bettered in sound quality by the class leaders Effective noise cancellation 24-hour battery life Comfortable build Sparsely featured comparatively Beaten for dynamics and timing No aptX Bluetooth

Love these headphones. Every feature brilliant. I recharge for a few minutes (when I'm in the middle of a podcast and just have to listen to the end) and it's almost 100% charged. Amazing. Sound is clear and rousing.

I may be a little bit unusual in having both these and the Sony XM4s, but to me these feel a bit lacking in terms of sound quality - nothing feels quite as 'alive' and punchy as it does with the XM4s. On the other hand, the sound isn't bad, and the noise cancelling is excellent.

“Bose's most popular headphones get a bigger battery, but drop some features.”

Don't fix what ain't broke....
