Enjoy great sounds and beats on the go - with the Bose QuietComfort noise-cancelling headphones. True-to-life sound and legendary noise cancelling block out the noise or let the most important things through - with the Quiet and Aware modes. Or you can create your own personalised mode that allows you to hear just as much environmental noise as is appropriate for the situation. These over-ear headphones come in an iconic and comfortable design, with an optional audio cable and microphone. So you get rich sound even without a Bluetooth connection.
