The USB Wireless Headphones and Mike are composed of a transmitter that connects via USB and a pair of headphones that contain the receiver. The transmitter functions as a USB audio device and sends audio to the headphones using infra-red. This apparently avoids interference with devices that use radio frequencies such as wireless mice, keyboards and wireless LAN. The range of the transmitter is approximately 7 metres.
The headphone receiver also contains a mike so it is possible to use them for voice chats as well.One AA battery supplies power for the headphones and a NiMH cell is included with the package. Charging occurs bu attaching the headphones to the transmitter unit using the supplied cable. The transmitter unit is bus-powered.
The headphones have neckband-style arms and also have a volume adjust dial. They weigh approximately 65 grams. The transmitter unit is 36 x 109 x 70 mm in size and weighs approx 65 grams.
