Sony preps 7.1-channel wireless headphones

Sony Japan is nearing the release of an extremely high-end set of wireless headphones, the MDR-DS7000s. A successor to the 5.1-channel DS6000s, the 7000s now simulate 7.1-channel surround sound, using a separate decoder box that supports AAC, DTS, DTS-ES and Dolby Pro Logic IIx. The box also has inputs for two optical audio devices and a single analog source, and can support several headsets simultaneously. Users are nevertheless more free from base stations, as the 7000s have been upgraded with onboard controls for volume and surround modes, as well as an AC adapter that allows direct charging.

Battery life is said to be 10 hours, despite powerful drivers that produce frequencies between 6Hz and 25kHz. A basic DS7000 kit should go on sale November 10th; the price for this is listed as "open," but spare headsets will cost 18,000 yen ($153) apiece. [via Impress Watch]
