Thank you for viewing. This product is a wireless earphone with Bluetooth connectivity and noise-canceling function. Functionality confirmed. I am selling this as it was stored in a closet. I have used it for many years, so there are some scratches on the main body that do not appear in the photos. Also, I dropped the right (R) earphone in the past, and while it still produces sound, there is a rattling noise. The left (L) side works normally, so I recommend it for those who want to try repairing it, use it as a single-ear earphone, or purchase a replacement right (R) earphone. Also, since it is an older model, I am unsure how long the battery will last. Here are the details from the HP: - Brand: SONY - Model: WF-1000XM3 - Features: Noise Canceling - Connectivity: Bluetooth - Battery Life: 6 hours + 18 hours (with charging case) Please contact me if you would like additional photos. I request no claims and no returns for this transaction. Also, I do not accept returns.
