SONY WH-1000XM3 Wireless Noise Canceling Stereo Headset, Black. Please see the official SONY website for product details. Updated to the latest software, and works without any problems. All accessories are included, so you can use it immediately upon arrival. The usage frequency was not high, so I don't think there is much deterioration, but please take a look at the photos and understand that this is a used item.
