Sony MDR-RF4000K Cordless Headphones

Sony has launched the shiny new MDR-RF4000K digital cordless headphones, which are designed to blend in perfectly in your living room, thanks to the new storage and charging dock that keeps it all wire-free.

* Digital RF headphone with 30m range and high quality sound
* Smart storage and charging dock cuts living room clutter
* High-comfort circum-aural design
* Crystal clear sound thanks to 40mm long stroke diaphragm and Digital Radio Frequency transmission

The wireless headphones also come with a NiMH battery that will delievr up to 7 hours of listening time. You can also use a single AAA Alkaline battery which will increase the usage by up to ten hours. We love the design and they would look right at home with all of our other gear.

The Sony MDR-RF4000K headphones will be available in April 2010, but so far we have no info on pricing.
