The SPK-9100 is a pair of wireless over-the-ear headphones from the Cables Unlimited company. Powered by a 900MHz transmitter running on two rechargeable AAA batteries, this model uses RF (radio frequency) technology to broadcast audio signals up to 165 feet for user convenience. Three selectable signal channels are available for attaining the best-possible signal quality at all times, with the unit's compact and lightweight design tailored to users who are frequently on the go and want access to a simple, cable-free listening experience. The inclusion of two 40mm drivers provides powerful woofer response to strengthen middle and low frequency outputting, providing audio playback that is both clear and balanced. Connecting via 3.5mm stereo jack, the SPK-9100's transmitter can easily connect to desktop and laptop computers, stereos, iPods and other portable media players. The unit is also fully compatible with other Cables Unlimited products, making it possible to work an external speaker into the user's setup for increased listening possibilities.
