Empty out your pockets and you are likely to have a Bluetooth headset, a pair of sunglasses along with a wallet and a phone. Now what if three of those four items could be combined together into a single gadget?

Tri-Specs packs dual microphones, speakers and Bluetooth connectivity into a pair of sunglasses with a set of retractable earbuds. To switch between calls and the MP3 player, users have to press the button on the rim of the glasses.

Extending the in-ear speakers turns on the power for the device. It can also do the usual voice dialing and prompts associated with Bluetooth headset. Oakley has had similar Bluetooth and MP3 player sunglasses for a while.

Tri-specs' glasses are yet to be available in retail but are expected to be priced around $200.
