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
