What is it?
The world's first wireless mobile phone headset.
What does it do?
It allows you to make and receive calls with your mobile safely in your pocket. Just like a normal hands-free attachment really, only there are no clumsy wires to get tangled or broken. It's the first product to use the long-awaited Bluetooth radio technology. Headset and phone communicate using low-power radio signals, thanks to Bluetooth chips in both. But it works only with Ericsson mobiles, and for the time being you'll need an adapter. The first truly compatible phones won't be available until later this year.
What's the competition?
Although hands-free kits with wires have become 10 a penny, this Ericsson is a real first. If you want a cordless headset, this is it. But the technology is proprietary, so all the big mobile players will be jumping on the Bluetooth bandwagon soon enough.
When can I get it?
It's available now, but at pounds 299.99 it's likely to appeal only to affluent early adopters.
