Help identifying a BOSE device
My relative gave me a BOSE device, but I can't figure out what it is. I am not sure if I can upload a picture here, so I'll try to explain what it is. Imagine the headphones that you put on your head, but without the actual speakers, basically just a frame (looks like something women use to keep there hair back).. On top of it there is a small round thing that looks like a small speaker, or maybe a camera, I am not sure. There is one long wire comes out from it, and on the end of it there is a connector that fits into the audio jack of the computer, but when I plug it in the audio jack on my computer nothing happens.. no sound, nothing.. So, I am confused what it is and how it should be used.
Pleas help to identify this device/accessory.
