This is LG Electronics' Bluetooth Style-i, an alternative to a Bluetooth headset for use with your mobile phone.

It's coming out in about a month, and is aimed at business people that want hands free conversations. It looks pretty neat and has a dial pad, but I think it is utterly pointless.

It can be clipped to a lapel or put in a shirt pocket, but works on speaker phone. So while you are having that high level, private conversation, you need to talk a little bit louder, to ensure you can be heard because the mouthpiece is further away. And anyone within earshot can hear the other end of the conversation too, as it blares out of the speaker.

I really can't see why anyone would buy this rather than a Bluetooth headset, but thankfully this pointless piece of technology is only available in the US, so while anyone elsewhere may think they are missing out, we very much doubt they are.
