Tired of tripping over cords, and accidentally ripping out headphone jacks? Go wireless, and listen to the freedom. The Sony MDR-RF920RK 900 MHz RF Wirless Headphones have a transmission range of 150 feet, allowing you to roam your house or yard without missing a beat (or word). The 900 MHz radio frequency delivers high quality sound, and the 30mm driver units provide deeper bass, lower distortion and a wider dynamic range.
These lightweight headphones are easily recharged by placing them on the transmitter, and the package includes rechargeable NiMH batteries.
