Glow are the first earphones to use laser light while providing advanced technological functions. The headset wires are constructed from fine sensors that pulsate light according to your heartbeat or the music you are listening to. An extra feature is a small microphone attached to Glow that allows you to make calls through voice command. The current Kickstarter campaign has more than passed its original goal and for a pre-order of $149, you can pick between a pair of Glow earphones in red, blue or green. Purchases are expected to ship by July of this year.
