Don't let your headphones cramp your style... go wireless, and roam free. Sony's MDR-RF960RK 900 MHz RF Wireless Headphones have a transmission range of 150 feet, allowing you to move about 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. The MDR-RF960RK come with automatic tuning for optimal reception of signal.

• Double Headband with self-adjusting mechanism conforms to the curve of your head for a fit that stays comfortable even during extended listening sessions. 
• Volume Control is rotary type for easy, convenient adjustment. 
• 3 Transmission Channels help ensure optimum signal reception; convenient tuning control on headphones. 
• Automatic Power On/Off for both headphones and transmitter conserves battery life; transmitter turns on when it senses an input signal; headphones turn on when you place them on your head.
