Black wireless ear-hook headset, with accessories. - Brand: SANWA Supply - Model: 400-BTWS4BK - Type: Wireless headset - Accessories: Instruction manual, charging cable, audio cable - Color: Black - Design: Ear-hook type Thank you for viewing. I used this to transmit TV audio to earphones via Bluetooth. I bought it because I often turned up the volume as it was hard to hear the TV. Used it a few times. It works well, but I prefer speakers, so I stopped using it.
