It's not all the time we have our Bluetooth headsets in our pockets to take a lengthy phone
call. There is a new phone concept that literally combines a mobile phone with a headset – dubbed the Kambala. You can literally remove the center piece and clip it onto your ear so you won't have to worry about lugging around another device. It is constructed out of a multi-layered polymer that houses all the electric components while the continuous flexi-screen creates a camouflage effect. The sensors on the screen will transmit an image on the inside of the phone to the outside; just like how a chameleon blends into an environment. Not only is it multi-functional, but also quite stylish at the same time.
