Clarion's WH104 wireless headphone package includes two wireless stereo headphone sets and an infrared transmitter. Each headphone set has foam on-the-ear earcups, a plastic adjustable headband, volume control, and a battery compartment for two "AAA" alkaline batteries (not included). An Auto ON/OFF microswitch in the earcups saves battery power by turning on the headsets only when audio is playing.
The infrared transmitter must be mounted in a location with a clear line of sight to the headphones. An automatic level control prevents input signal overloading. Connect the audio output of your media player (in-dash DVD receiver, mobile DVD player, VCR, etc.) to the transmitter's audio inputs, put on the headphones, and slap in a video instant mobile theater! Warranty: 1 year.
Important Note: The headphones are for passenger use only. Most states prohibit the use of headphones by the driver while operating the vehicle.
