I would love to buy two pairs of headphones, wireless, that would fit into my briefcase. When I teach music, I currently carry two pairs of cheap in ear phones (one of them is a black samsung pair of in ears that came with my cell phone, not bad sound tbh) and an extension cable with a dual minijack splitter adapter. Both headphones plug into the splitter, and the extension cable goes into the headphone jack of my phone. My student uses one pair and I use the other to monitor the music from the phone that he plays along to. Average quality sound is fine, it's only for teaching purposes. The problem is that there's too many cables to deal with and the headphone cables always get a bit tangled up which wastes time. I just want to pull out two pairs of wireless headphones, enable bluetooth on my phone (samsung galaxy S2) and off we go. Something small like this would be the kind of thing where the earpieces fold flat. Two pairs of those would probably fit in my case.
Is there such a thing in wireless and if so, does anyone know if a phone can deal with two bluetooth devices simultaneously? If not, I might still buy two pairs of those JVC's as the wires would probably be easier to manage plus it's still more hygenic than giving students in ears to wear (I do clean them before each use).
