Bluetooth wireless headset, black. - Brand: Panasonic - Model Name: RP-HD300B-K - Type: Wireless headset - Bluetooth: Yes - Color: Black - Instruction manual included, original box included - USB charging cable included - Made in China Thank you for viewing. The "detachable cable" accessory was never used, but is not included. The market price at the time of sale was ¥11,730 (including tax). I purchased it three years ago, but I haven't used it much (I use Bluetooth earphones frequently) and it has been stored away. There is some wear and tear as shown in the photos. Thank you for your consideration.
