Wireless headphones made by BIGBIG WON, with a USB dongle and microphone. - Brand: BIGBIG WON - Model Name: Wireless Headphones - Included Accessories: USB dongle, microphone - Design: Black headband and earcups with metallic accents - Features: Buttons located on the left and right earcups Thank you for looking. I used these only once. It was my first headset, but I realized I'm not suited to wearing headphones for long periods. I switched to earbuds, so they're in good condition. I also thought the sound quality was good for the price.
