Now you can go where you want to go, and listen to your favorite music - indoors or outdoors - without wires. The Altec Lansing AHP612 wireless stereo headphones easily connect to TVs, VCRs, DVD players, stereo systems, iPods and other portable audio players. Omni-directional 900 MHz technology delivers clear, accurate sound through walls, floors and ceilings up to 150 feet from the transmitter base. The sound is further clarified by the headphones' closed ear-cup design, which minimizes ambient sounds. And the AHP612's high-capacity batteries (included) are recharged simply by placing the headphones on their transmitter base.
