The Bose QuietComfort Ultra Earbuds (2nd Gen) in Black are true wireless noise-cancelling earbuds. They use Bose active noise cancellation to reduce distracting environmental sound. They are made for music, calls, travel, commuting and workouts.
CustomTune ear calibration analyzes the acoustic response when the earbuds are inserted. It adjusts sound and noise cancellation to the listener's ears and fit. ActiveSense technology works with Aware Mode to reduce sudden spikes in outside sound while still letting surrounding audio through.
There are three listening modes. Quiet Mode provides strong noise cancellation. Aware Mode lets environmental sound through. Immersion Mode combines noise cancellation with Bose Immersive Audio. TrueSpatial Immersive Audio places the perceived soundstage outside the listener's head, with Still and Motion modes for when the listener is stationary or moving.
