The Bose QuietComfort 35 II headphones have a dedicated Alexa button, letting you activate Amazon’s AI assistant on demand. If you don’t have Alexa, no worries, that same button also lets you toggle among three different levels of noise cancellation. In fact, there are intuitive buttons all along the ear cups. Rather than having to rely on inconsistent button-free touch controls, Bose’s design ensures that nothing comes between you and the enjoyment of your music. You can also take crystal-clear calls with the QuietComfort 35 II, the dual mics actively filter out anything that isn’t your voice, so you can take calls in even the noisiest of environments. The ear pads are generous and comfortable, which is good, since you’ll be able to listen to 20 hours or more of whatever you want. They’re now on sale for $279 at Best Buy, a $50 Black Friday discount.
