Romania-based designer Shepeleff Stephen, an engineering student at the Transylvania University of Brasov, has developed Bluetooth headphones called “Q-SOUND” that generate power directly from the sun. Solar powered Bluetooth stereo headphones, the Q-SOUND, were elaborated in purpose to overcome the performance limitations of time use and energy-efficiency during listening to a radio or enjoying music, using any MP3 player connected to electronic audio equipment. The Q-SOUND headphones represent a type of on-ear, headband design with incorporated flexible amorphous silicon solar cells. All the outer pieces of headphones have a satin silver finish, since they’re developed from flexible plastic and all the inner pieces offer more color because they’re made from rubber-based materials. This contrast is made purposely to provide a visual accent on the solar cells and to confer a light look on the design. The solar cells are placed on the headband piece and cover.
The Q-SOUND is a Bluetooth headset which could be used with any Bluetooth-enabled device such as digital audio player/MP3 player. If connected with your Bluetooth-enabled cellphone, the Q-SOUND allows you to answer calls as well. Other than the wireless Bluetooth connection, the headphones can also be wired to all DAPs featuring a 3.5mm stereophonic jack plug. Q-SOUND headphones have inside two removable rechargeable NiMH batteries with an electric capacity of 800mAh and operating voltage 1.2V and a fully charged headset is able to run for up to 40 hours. For Q-SOUND headphones one hour of sun yields more than 2.67 hours of working at maximum volume selection.
