QC35 around-ear headphones offer noise cancellation when used either with the wire or wireless. It also has a custom-engineered Bluetooth system for a consistent connection anywhere. The QC35 has up to 20 hours of battery life from a rechargeable lithium-ion battery. It also has buttons placed on the right earcup – on/off, music volume, play/pause, and answer/end calls for more convenient interface.
According to the company, with microphones inside and outside the earcups, the QC35 senses, measures and sends unwanted sounds to two proprietary digital electronic chips – one for each ear, which respond with a precise, equal and opposite signal in less than a fraction of a millisecond.
