Two Modes — QUIET and AWARE
The QuietComfort 45 headphones feature just two settings, both achieved using a new active noise cancellation system and new electronics package. In QUIET Mode, microphones inside and outside the earcups combine with a proprietary digital chip to sense, measure and respond to more unwanted sounds in mid-range frequencies — those typically found in commuter trains, busy office spaces, and cafés. The now-famous “whoosh” associated with Bose noise-canceling technology happens in a fraction of a millisecond to tune out entirely or enjoy music, podcasts, or movies with lifelike clarity, detail, and no distractions. In AWARE Mode, QC45 headphones switch to full transparency, where everything is heard again – just as naturally, clearly, and quickly — without ever taking them off.
