Bose QuietComfort 45 Bluetooth Wireless Noise Cancelling Headphones – Triple Black (Renewed)

Noise cancelling wireless headphones – 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.
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.
