I've got to give this Q-Sound headphone concept from Shepeleff Stephen top marks for its design. Not only does it look great, it is also innovative in its use of solar technology.

After all, it makes sense to power Bluetooth headphones with a small solar panel stretched across the headband—an area that could be easily exposed to the sun. Outside of that, the Q-Sound would also be able to handle calls or plug into a 3.5mm jack should the need arise. All-in-all the Q-Sound is a great idea—a concept I can definitely see transitioning into a real-world product. [Ecofriend via Gizmag via Ubergizmo]
