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

Light weight

so you can wear them comfortably for hours on end

24 foot transmission range

for listening enjoyment throughout the room; lets you sit back from the TV set and still enjoy TV sound

Up to 100 hours of battery life

with optional AA alkaline battery; up to 30 hours life with supplied rechargeable NiCad battery

PET diaphragms

ensure high rigidity for minimum distortion; low mass for extended high-frequency response out to 22,000 Hz

Mute function

to avoid noise through the headphones; cuts out the sound when no audio signal is available

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

Two audio inputs

let you switch between sources, for example, a Hi-Fi Receiver and a television

High-power infrared transmitter

incorporates multiple Light-Emitting Diodes (LEDs) for extended coverage range

Rechargeable battery

(supplied) saves repeated trips to the store; automatically recharges when you place the headphones on the supplied transmitter

90° transmission angle

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

Single volume control

in one earpiece conveniently adjusts the volume for both channels

Easy connection

to TV, VCR and audio systems, through the supplied connecting cord and plug adapter

Open-air design

lets you continue to hear ambient 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

Complete kit

including high-powered transmitter/recharger, headphones, rechargeable battery, connecting cable, UniMatch® plug adapter and AC power adapter

Ferrite magnets

combine high energy and small size, for ample sound output

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
