Sony MDR IF240RK Ear-cup Headphones - wireless

The Sony Wireless Headphone System has everything you need to enjoy your music without wires: a high-powered transmitter/recharger, headphones powered by a rechargeable battery, a connecting cable, a UniMatch plug adapter, and an AC power adapter. The system easily connects to TVs and VCRs as well, letting you turn up the volume while people nearby are sleeping or wanting some quiet time. The system has a maximum range of 24 feet and a transmission angle of up to 90 degrees, and lasts up to 35 hours on a full charge. The open-air design of the headphones lets in ambient sound. You can recharge the battery by placing the headphones on the transmitter. Volume control is provided in one earpiece that adjusts volume for both channels, ferrite magnets ensure the ample production of sound, and a self-adjusting headband automatically adjusts to your head's shape for maximum comfort. The system automatically turns on when you put it on your head, so there are no cumbersome switches or buttons to flip on.  more
