Aliph has launched a new version of its Bluetooth headset - the scarily-named Jawbone NoiseAssassin.

The £79 NoiseAssassin part of the name refers to the rather brutal way the earpiece cuts off whatever is going on around it, so the wearer can hear and be heard when making a handsfree mobile phone call. Maker Aliph says the Jawbone uses a Voice Activity Sensor (VAS) with military-grade noise cancellation designed for use in airports, pubs,mclubs and other busy locations. says its VAS system blocks out as much as 10 times as much background noise as competitor products.

The Aliph Jawbone NoiseAssassin Bluetooth headset weighs a scant 10 grammes, making it seriously impressive that anything more than a clip and the earpiece itself can be included.

Perhaps yet more impressive was the attention the tiny device's launch attracted. The Jawbone NoiseAssassin got its UK launch last night at a swank house party at which nu-wave band New Young Pony Club played a DJ set.

Before the party got under way, we were given a demonstration of how users would be able to make and receive calls despite the din.

In the live demonstration, showed just how effective the noise cancellation feature of the Bluetooth headset can be.

First, a food blender was set to mix a noisy concoction of fruit and ice, then we were treated to a rock anthem blasting out. When used in standard mode - with no special setting to cut the extraneous cackle all around - we could barely hear the presenter. With VAS switched on, he came through loud and clear.

In both cases, Jawbone showed it was possible to conduct a hands-free chat despite the cacophony of noise going on in the background.

The Jawbone goes onsale imminently through retail stores such as Carphone Warehouse and the Apple Store and will be available in a choice of black, silver or rose gold.
