* Cordless design lets you move around the room and still enjoy music or TV
sound tracks; lets you turn the volume up late at night -- without
disturbing anyone else.
* Easy connection to TV, VCR and audio systems, through the supplied
connecting cord and plug adapter.
* Light weight so you can wear them comfortably for hours on end.
* Open-air design lets you continue to hear ambient sound.
* High-power infrared transmitter incorporates multiple Light-Emitting
Diodes (LEDs) for extended coverage range.
* 24 foot transmission range for listening enjoyment throughout the room;
lets you sit back from the TV set and still enjoy TV sound.
* 30 mm diameter drive units are larger than many portable headphones for
deeper bass, lower distortion and wider dynamic range; frequency response
extends down to a low 18 Hz.
* Rechargeable battery (supplied) saves repeated trips to the store;
automatically recharges when you place the headphones on the supplied
transmitter.
* Up to 100 hours of battery life with optional AA alkaline battery; up to
30 hours life with supplied rechargeable NiCad battery.
* 90 degree transmission angle (maximum) for uninterrupted listening as you
move around the room.
* PET diaphragms ensure high rigidity for minimum distortion; low mass for
extended high-frequency response out to 22,000 Hz.
* Ferrite magnets combine high energy and small size, for ample sound
output.
* Wide headband with a separate self-adjusting band conforms precisely to
the curve of your head; stays comfortable, even after listening for hours
on end.
* Mute function to avoid noise through the headphones; cuts out the sound
when no audio signal is available.
* Automatic power switch for both the headphones and transmitter conserves
battery life; when the transmitter senses an input signal, it turns on;
the headphones turn on when you place them on your head.
* Single volume control in one earpiece conveniently adjusts the volume for
both channels.
* Supplied connecting cord with Sony UniMatch plug that goes to the
headphone output of your high fidelity system, TV set or VCR; UniMatch
system accommodates either the phone jack on high fidelity components or
the minijack found on video components.
