Go the Distance With Headphones by Sony

MDR-RF865RK Wireless Headphone and MDR-NC13 Noise Cancelling In-Ear Travel Headphones

LONDON--(Marketwire - March 29, 2011) -

  • MDR-RF865RK: wireless headphone system with stylish recharging dock and 100m range
  • MDR-NC13: noise cancelling in-ear travel headphones with long 100hr* battery life

Two new headphones from Sony let you enjoy your favourite sounds where and when you want to.

MDR-RF865RK wireless headphone system

With a transmission range of up to 100m, the MDR-RF865RK wireless headphone system lets you enjoy rich, immersive sound anywhere in the house. Light and comfortable to wear, it's an ideal companion for watching TV, listening to the radio or playing video games without disturbing others - and with no clutter from extra wires.

40mm driver units ensure smooth, rich audio with a deep bass response, while wireless interference noise is reduced for a clear, transparent listening experience.

It's easy to set sound levels with the headphone's conveniently-mounted volume control. This saves you the trouble of getting up to adjust volume on your TV, radio or music player.

When it's not being used, just rest the MDR-RF865RK on its elegant charging dock. The headphone recharges in just 3.5 hours, with no need to fiddle with power leads. With its rechargeable batteries fully charged, you'll enjoy a generous 25 hours uninterrupted listening time. The headphone also turns off automatically to save power when it's placed back in its charging dock.

MDR-NC13 noise cancelling headphones

Ideal for music-loving travellers, the new MDR-NC13 immerses you in a blissful world of unspoiled, crystal-clear sound.

The noise cancelling design reduces ambient noise by approximately 87.4%, cutting out background distractions if you're on the bus or in the air. The closed-type vertical in-ear design combines superb sound quality with excellent wear comfort.

The headphone's energy-efficient design provides plenty of battery stamina for the daily commute or longer trips away from home. While the MDR-NC13 comes supplied with a manganese battery, a single AAA alkaline battery (not supplied) boosts listening time to a full 100 hours.

The new MDR-RF865RK wireless headphone system and MDR-NC13 noise cancelling in-ear headphones from Sony are available from April 2011.
