Hi-Fi cellphone concept

LG recently announced its Design the Future competition winners, where the Hi-Fi cellphone was one of the winners, being a “handset” of sorts which also functions as a pair of headphones. When folded, it is capable of fitting into your notebooks ExpressCard slot, or perhaps even your pocket. When fully opened, it works as a smashing pair of stereo headphones. It would be interesting to figure out where the microphone is on this thing, but then again this is a concept, and conceptual devices rarely concern themselves with practical engineering aspects – well, most of them, anyways.
