Motorola demonstrated possibly the smallest Bluetooth headset at CES (the International Consumer Electronics Show) this year. The Mini Bluetooth Headset weighs just 7.5g and is only slightly larger than an in-ear earphone.

It's good for one and half hours talktime and seven and a half standby. It also means you won't look quite as silly sporting one, but don't tell the Americans that – they appear to be all the rage over here at the moment.
