Bose QuietComfort 35 II wireless noise-cancelling headphones in black. These over-ear headphones feature the iconic Bose acoustic design with comfortable ear cushions and an adjustable headband. This set includes the original hardshell carrying case, a 3.5mm audio cable, and an airplane adapter. Please note that the internal battery no longer holds a charge and the device will not power on, making this an ideal purchase for parts, repair, or for those who can utilize them in a wired capacity if applicable to their technical needs.
