Q-SOUND is a concept device designed by Shepeleff Stephen, an engineering student at the Transylvania University of Brasov. It generates power from the sunlight.
This gadget is not only eco-friendly, but it’s also a great purchase for those of us who are tired of using regular Bluetooth headphones that need charging all the time.Having two removable rechargeable batteries with an electric capacity of 800mAh (1.2V), a fully charged headset is able to run for up to 40 hours (one hour of charging = more than 2.5 hours of running time). Also a wired connection is possible with the included 3.5 mm jack.
