Thanks for the responses. Yeah I took this photo. I too tried image recognition apps (Googles/Pounce) without success. Wow this has got me stumped!

Hi All... found a pair of full-size headphones lying around in the office that I cannot identify? The brand isb capital "D" with 3 dots underneath. It has a small USB (mini-B?) port inset in the left-hand earphone which is so deep that I had to shave the plastic collar off a standard USB cable...
