Bose QuietComfort 20

Bose’s first in-ear headphones to offer noise-cancelling tech use dual mics in each lug to detect and counter outside sounds, insulating you in a cocoon of your own tunes. However, press a button on the slightly bulky control unit and said mics can also allow you to hear what’s going on around you, via the miracle of “Aware mode”. This lets mid to high frequencies through so you can hear station announcements and the like. The battery provides up to 16 hours of noise cancellation on a single charge, with a full rejuicing via USB taking two hours.
