JVC HA-WD100 headphones, which achieve high sound quality with a digital wireless system. - Brand: JVC - Model Name: HA-WD100 - Wireless System: Digital Wireless - Communication Distance: 30m - Frequency: 2.4GHz - Accessories: Charging Dock, Instruction Manual - Charging Time: 10 hours It came out of the closet, and I don't know when it was purchased. I don't know the price, but I want to get rid of it, so I'm listing it. Since it is unknown whether it can be used, it will be treated as junk. No claims accepted.
