Sony has announced a new set of headphones called the MDR-HW700DS digital surround wireless headphones. The headphones use Virtualphones technology to reproduce the soundstage of a multichannel speaker system. A 9.1 channel system adds a pair of surround back speakers and a pair of front high speakers to the normal 5.1 set up.
The headphones don't actually have nine speakers inside. The wireless connectivity doesn't come at the detriment of sound quality. Sony uses HDMI connectivity for the headphones offering uncompressed audio transmission. Dual wireless bands are supported with 2.4GHz and 5 GHz.
Three different modes allow the user to choose the best mode for what they are doing. Those modes include Cinema, Game, and voice settings. Sony uses pressure-relieving luxury ear cushions for the headphones to make them more comfortable during extended use.
The driver inside the headphones is a 50mm unit and the 700DS headphones allow the pass through of 4k video content in original quality to a projector or TV. The headphones will ship in April at an undisclosed price.
