Query: Wireless Headphones

The vendor sent the headphones very quickly. However, they were classified as 'new' but the box had been opened and the battery compartment cover was scuffed, indicating they were used. But they work just like new. I like these battery operated headphones because I do not need to keep putting them into the transmitting unti to recharge. The batteries actually last quite a long time.
