These headphones feature active noise cancellation, as well as a noise-rejecting, dual-microphone system that renders phone calls clear even in windy or noisy situations. Its Sidetone feature allows you to hear your own voice, despite the noise reduction. With one 2.25-hour charge, these headphones can stream audio for up to 20 hours; using the included 3.5mm audio cable, the QuietComfort 35's noise-reduction capabilities will last for up to 40 hours before requiring recharging. 

These headphones, with Alcantara earcups that rotate for safe storage, also sport volume-optimized EQ intended to maintain frequency balance across any output level, while their active noise cancellation mitigates unwelcome dins such as street sounds, airplane cabin noise, and more. The right earcup sports volume controls and a multi-function button, which can control play/pause, skip-track, rewind, fast-forward, and your phone's default voice assistant. In addition to the 4' 3.5mm audio cable, a carrying case and a 12" charging cable are also included.
