MDR-RF4000K

Wireless digital RF headphones

Dierences in details

40mm drivers deliver deeper bass, lower distortion and wider dynamic range.

Stay comfortable as long as you listen

A wide, self-adjusting headband distributes the headphone's weight over a wide area, reducing pressure and improving comfort.

Listen from a distance

Radio Frequency (RF) transmission sends signals from the transmitter to the headphones, allowing high delity sound reproduction. You can enjoy the accompanying reception range – up to 100 feet – even when you move outside the line of sight of the transmission.

Battery life for extended viewing

The supplied rechargeable NiMH battery lets you enjoy up to eight hours of continuous on a single charge1. The slim, folding design ts snugly into the charger (included). Substituting a single AAA battery for the rechargeable NiMH pack provides 10 hours of power.
