Here's an odd-looking Bluetooth ear plug-in: the iota BTH-738 from Touch, which recently got the FCC nod, is unlike any other traditional Bluetooth headset, at least in design.

As usual, the iota BTH-738 features a multi-function button to make/receive calls and power on/off the device. If your cell phone supports voice tags, press the button and speak out the contact's voice tag and get connected.

The volume control buttons are placed on either side of the ear-piece. Muting requires you to press both buttons for 1 second. I suppose it's easy to remember that when driving down the freeway at 100mph.
