I bought this new, but I also use other headphones, including SENNHEISER, and it's been sitting unused since I first tested the sound. I've only used it for about 4 minutes in total, but I did check the noise cancellation and touch sensor functions. There were no problems at that time. All accessories are unused and included. *See photos* Wireless headphones with noise-canceling function boasting a maximum playback time of 30 hours. - Brand: SONY - Model Name: WH-1000XM3 - Color: Black - Features: Noise Canceling - Bluetooth Version: Bluetooth 4.1 - Playback Time: Up to 30 hours - Supported Codecs: LDAC, aptX HD - Assistant Function: Google Assistant - Accessories: Carrying case Thank you for looking.
