Does anyone know of any bluetooth stereo headphones that can answer two different phones? I travel quite a bit and am required to use hands free options for my work phone. I also carry my personal phone as well. The Kinivio headphones I bought are OK, but I can only pair to one phone at a time. Is there anything out there that can pair with two phones? To be even more picky, I'd prefer adjustable stereo headphones that fit over the top of my head (big head), and not with a neck band. Thanks for any input.
