Alongside refreshes galore to their Surface hardware lineup of laptops, all-in-one devices and convertible PCs, Microsoft did have a surprise announcement as part of their media event earlier today. This included a whole new product genre under the Surface brand in the form of headphones.

The new Surface headphones join the current trend of audiophile-rated wireless headphones, which sounds like a misnomer in itself, and comes with 13 levels of noise cancellation with 8 microphones for the process controlled via an adjustment dial as per Anandtech. This is an over-the-ear style headphones offering beam-forming for hands-free calling and Cortana support for when you want to use Microsoft's take on the virtual assistant. Pairing via Bluetooth and coming in the now-standard Surface gray color scheme, the Surface headphones are priced at $349 and will be available later this year.

The launch of Microsoft Surface marks the beginning of a new technology category and a user-interface revolution. Surface, Microsoft's first surface computer, provides effortless interaction with digital content through natural hand gestures, touch and physical objects. Surface computing breaks down traditional barriers between people and technology, changing the way people interact with all kinds of everyday information - from photos to maps to menus.

Key features demonstrated in the videos included:

• Multi-touch ability.
• Recognition and syncing of wireless devices by placing on touch panel
• Ability to identify non-digital devices, such as a drink glass, based on shape.
• Hand gesture system to further interact with the touch panel.
• New, non-windows based interface.

The videos really speak for themselves. According to the website, Surface technology will be
available in Winter 2007.
