Bose spent more than 40 years of research in pursuit of the best noise cancellation in the world. Then they obsessed about making it wireless. The result: QuietComfort 35 wireless headphones. Free yourself from wires and connect easily to your devices with Bluetooth and NFC pairing. A volume-optimized EQ gives you balanced audio at any level, while a noise-rejecting dual-microphone system provides clear calls, even in windy and noisy environments. These are one of Bose's best headphones. In making them wireless, they had one goal: seamlessly merge Bluetooth and their Acoustic Noise Cancelling technology together with no compromise to the technologies or the audio performance that they're known for. Try them for yourself - then try to live without them.
