Wireless Bluetooth headphones, the ATH-M20xBT, with a simple and stylish design. - Brand: audio-technica - Model Name: ATH-M20xBT - Connectivity: Bluetooth - Type: Wireless Headphones - Color: Black I purchased these headphones from a certain shopping site, where they had been used for about a week, and I used them for about a week myself. I'm selling them because I want headphones with noise-canceling. There are no tears in the earcups or elsewhere. Thank you for looking.
