SONY Sony Mono Bluetooth Headset MBH20 White Used This item was kept as a spare, so it has been used very little. I think it's a valuable item that is not often available. I have confirmed that it charges and works for calls. When I used it, I used different ear tips, so the included ear tips are unused. The original box has some damage. It's an old item, so I think the battery has deteriorated, but I didn't feel any extreme deterioration. There may be minor scratches and dirt from use, so please understand that this is a used item before purchasing.
