There are all manner of uses a Bluetooth headset can be put to. With one of these handy devices plugged into your lughole, you can make and receive phone calls in the car, for instance, without taking a hand of the wheel. You can take notes while on an important business call, or use your computer with both hands.
And, if you happen to be in a dodgy area of town late at night, using a headset saves you from having to whip out your mobile for all to see when you have an important phone call to make. Wearing one might make you look like a bit of pillock and you're almost certain to draw odd looks when you look like you're talking to yourself, but I reckon everyone from businessmen to ladies who lunch should own one of these essential bits of kit.
How on earth do you choose from the hundreds of devices on the market, though? One way to do it is to look for extra, innovative features. Take the Aliph Jawbone Assassin that Riyad reviewed recently. It was expensive at £75, but sumptuously designed, and its ingenious jaw movement sensor set it apart from the throng.
With its snappily titled BIZZ headset, Bluetrek is hoping that innovative features will help potential customers choose its product over others, too. It's not as expensive as the Jawbone 2 - £20 to £30 seems to be about the sweet spot for Bluetooth headsets - yet it offers a feature that most headsets do not. It doubles up as a USB microSD card reader.
Pop off the cap and earpiece assembly, and underneath you'll find a tongue-style USB connector, and just above this is a slot for a microSD card. Plug it into any nearby USB socket and the BIZZ is transformed from communications device to a quick and convenient data store. For carrying around presentations, spreadsheets and a collection of important office documents, even large amounts of music and video, this is a great idea.
It means if you forget to take a USB cable with you, you can quickly transfer data from a smartphone (most seem to have a microSD slot these days) to a laptop or desktop PC and back again regardless of whether or not that machine has a card reader. It also means you're not tied to a small amount of built-in data since you can have as much stored in your earpiece as you like - up to a limit of 8GB on SD/SDHC card types (note: no memory is included in the box).
