Used only once, Bose QuietComfort Headphones, Carry Case, USB cable and charging block. Been in my drawer but don't have the original box or instructions. Take charge of your music and stride along to the beat. High-fidelity audio and legendary noise cancellation work their magic by sealing you in, eliminating distractions, and letting you dive deep into your own rhythm. Toggle between Quiet and Aware Modes, or create a Custom Mode and adjust outside sound to the moment. The design is iconic and the comfort lasting, while an optional audio cable with an in-line microphone plugs you into sound as bold as you, even without a Bluetooth® connection.
