Bose QC 15 QuietComfort 15 Wired Over-ear Headphones Case AS IS For Parts Repair. Green light comes on to show power. Can only get sound occasionally,  but the cord connection is bent as shown in pics. They might work with just a new cord as sound works if you move the cord around. Already bought new ones, so did not buy new cord. Head foam has some deteriorating areas. Shipped USPS Priority Mail.
