LG's just released a Bluetooth headset that is targetting the sportier type. With an IPX3 rating, it can handle sweat but don't expect to run in the rain with this. It has earbuds that retract into the headset, which makes it pretty convenient and less likely to get tangled up.
It's shaped in a contoured, around-the-neck style and uses LG's quad-layer speaker technology and incorporates a digital MEMS microphone.
Retailing for US$129.90, it's currently an AT&T exclusive, with no word if it'll eventually be sold elsewhere and outside the US.
