Another concept marches into our lives in the form of the Q-Sound solar powered headphone. The concept is quite simple; a bunch of solar powered cells are present on the dorsal portion of the headband that absorbs the rays of the sun to generate power. The charge can last up to 2.6 hours. Thanks to the two NiMH batteries, the headphones can hold up a charge of up to forty hours. The best part is you can wire it up to your media player’s 3.5 mm jack if there isn’t any charge left for Bluetooth playback.

Even if the Q-Sound solar powered headphones make it from concept to retail, they will still be quite expensive. This is because the solar cells are created specially on a flexible plastic.
