Japan's Willcom sure doesn't have a shortage of handsets that rock the foundation
of what a wireless phone should be
, so enter this entry: a handset inside a headset. Willcom's conceptual "handset" here (that will never be in your hand) will accept a Willcom W-SIM
so that the wireless headset sitting on top of that noggin can actually make independent voice calls as well. Since W-SIMs integrate a PHS wireless receiver right onto the card itself, it's easy to give non-wireless devices that capability -- so why not let that music-laden set of headphones have some fun, right?
