Aerielle, not to be confused with the fishy tart of Disney fame, is an RF system that transmits audio to a pair of stereo headphones with relative accuracy and fidelity. The advertised 15-foot radius is false but otherwise these seem like a good solution for those not wishing to be tethered to their MP3 players or need to watch TV while not waking the demons in your basement.
The device transmits on the low end of the FM band—no word if these things can transmit every radio in the vicinity or just the headphones—but they seem like a fairly good solution to a common problem.
