"The Q-sound, designed by engineering student Stephen Shepeleff, is using blue to go green. The Q-Sound, a concept pair of headphones, uses bluetooth to connect to any compatible music playing device or cell phone. The way it continues to stay alive after so long is the solar panels that make up the headband. Shepeleff says that one hour of sunlight into the panels can allow for 2.67 hours of music on full volume. The Q-Sound is equipped with rechargeable batteries that can allow it to last up to 40 hours, as well as a 3.5mm jack just in case the music device is bluetooth enabled. Good excuse to get people to go outside!"^^<http://www.w3.org/2001/XMLSchema#string>
