Premium, personalised audio with CustomTune calibration, Bose's best in-ear noise cancellation, and a secure, all-day comfortable fit.

Calibrates audio to the unique shape of your ears on every power-on — a perfectly tuned listen, automatically.
Quiet Mode for full ANC, Aware Mode for transparency, with smoother updated ActiveSense that tames sudden loud sounds.
Spatialised, theatre-like sound that reaches beyond your earbuds, so music and video feel wider and more lifelike.
Noise-rejecting mics filter out background noise and wind for clearer calls wherever you are.
