Sony Introduces 9.1ch digital Surround Wireless Headphones

Sony's new MDR-HW700DS digital surround wireless headphones are coming this month, promising to offer you a cinematic sound experience in the comfort of your home.

Adding more depth to the 9.1ch digital surround headphones is a choice of sound effect modes for movies, gaming or news- and talk shows. For instance, the new "Cinema" mode recreates a feeling of being at the cinema. And you can also enjoy detailed uncompressed multi-channel surround sound via the digital wireless transmission that eliminates noise and interference from other devices in the home.

Exclusive to Sony, Virtualphones Technology (VPT) reproduces the soundstage of multi-channel speakers to create an acoustic space with authentic surround sound. In addition to the 5.1ch surround speaker, surround-back (2ch) and front-high speakers (2ch) create a 9.1ch surround sound.

An HDMI connection supports uncompressed audio transmission. And by using a dual band connection (2.4GHz and 5GHz), Sony says that smooth wireless transmission without any disruptions is ensured.

The MDR-HW700DS is crafted for a comfortable fit over long periods of use with the pressure-relieving ear cushions. The headphones feature 50mm driver units and have a battery-life of up to 12h. In addition, the MDR-HW700DS allows native 4K video content to be passed through in its original quality to a 4K TV or projector.

Sony's new Home Wireless Headphones range also includes the MDR-HW300K with uncompressed digital-wireless transmission as well as the MDR-RF811RK entry-level wireless headphones with 28h battery life.

The new, MDR-HW700DS, MDR-HW300K and MDR-RF811RK wireless headphones systems are available now.
