Now there’s a smarter way to experience high quality sound in privacy and comfort while you’re listening to music or watching TV.

The luxuriously styled MDR-RF4000K digital cordless headphone from Sony offers fabulous digital sound for your favourite AV entertainment. It’s also designed to fit in perfectly with today’s living rooms, thanks to a unique new storage and charging dock that cuts unsightly wires.

Discreetly styled to complement the modern lines of your TV, the slim, convenient storage case doubles as a cable-free battery charger. After use, just fold the ear cups flat and the MDR-RF4000K stows neatly away while the battery recharges.
Digital RF transmission ensures clear, secure signal reception over a range of up to 30m. The headphone’s closed-type design cuts sound spillage, so there’s no need to disturb others while you’re enjoying the action packed finale of a favourite movie.

Exceptional audio quality is assured by the headphone’s powerful 40mm long-stroke diaphragm. You’ll be rewarded with beautifully detailed, immersive reproduction of movie soundtracks and dialogue, music and more.
The closed-type design also features swivel circum-aural cushions and a parallel-link self-adjusting headband for superb wear comfort, even for extended listening periods. Thanks to a convenient volume control on the headphone, there’s no need to reach for the remote to turn sound up or down.

The power-efficient design allows up to 7 hours continuous listening time between charges of the NiMH battery. Alternatively, slip in a single AAA alkaline battery and enjoy up to 10 hours listening without a break. An auto power-save feature switches off the headphone when it’s not being used, extending listening time still further.
