I'm selling this headset because I ended up using a different one and have kept this one in storage with minimal use. I've used it about 20 times, and each time was for a short period. Please check the photos for the condition. I have recently confirmed that the audio works. I would appreciate it if those who understand that this item has been stored at home would consider purchasing it. Thank you very much.
