Sony MDRRF855RK over-ear wireless headphones

General

Relaxing on the couch with your favourite music or film, without being in any way hindered by tangling cables that are always just a little bit too short? With these wireless headphones by Sony, it's possible!

Wireless

Powered by a built-in Ni-MH battery, these headphones have an impressive 18-hour playback time. If that's not long enough for you, you can also choose to use alkaline batteries, extending the battery life with another 10 hours! The built-in battery is easy to charge, all you have to do is place the headphones in their docking station and seven hours later, they'll be good to go. This docking station also doubles as the transmitter that sends the audio signal to your headphones. You can easily connect it to an audio source using the mini jack connectors, after which it offers you a wireless range of up to 100 metres!

Sound reproduction

As far as audio quality goes, these Sony headphones are absolutely excellent. Their 40mm neodymium drivers allow for a balanced and detailed sound, which is further enhanced by the 10 - 22,000Hz frequency range. As such, even the smallest details will remain clearly audible at all frequencies and volumes, without distorting the sound. You can even choose to boost the low frequencies, which is especially effective for films and sports programmes. Finally, you can adjust the volume on the fly, using the simple slider that's built into the headphones.
