Product code: Sony WH-1000XM4 Active Noise Cancelling Bluetooth Headphones READ newest DESCRIPTION!!
Partially functioning. Headphones work, but when using active noise cancelling, the headphones emit a high pitched squeal. Can use the headphones perfectly fine without active noise canceling. I have read some online articles of people saying they are able to fix it by cleaning the inner ear cup, but I do not have time to do this myself. Connect via Bluetooth or 3.5 mm newest audio jack. Charge with included USB 3.0 to USB cable. Includes original box and carrying case. Ships via UPS.
