Bose 884367-0900 QuietComfort Wireless Over-Ear Headphones - Black The perfect balance of quiet, comfort, and sound. Bose uses tiny mics to measure, compare, and react to outside noise, cancelling it with opposite signals. Bluetooth range-up to 9 m (30 feet).
HIGH-FIDELITY AUDIO: The TriPort acoustic architecture offers depth and fullness. Volume-optimized Active EQ maintains balanced performance at any volume, so bass stays consistent when turned down and the music remains clear when turned up.
QUIET AND AWARE MODES: Choose Quiet Mode for full noise cancelling, or Aware Mode to bring the outside into the around ear headphones and hear your environment and your music at the same time.
