We know our raves here at Genie better than most, & if there is one thing we have learnt is that the more lights, the cooler you look. Enter the Sound Sensitive Light Up Glasses then. Comprising of two modes, talking & music, the Sound Sensitive Light Up Glasses illuminate to the sound around them, what a beautifully cool concept. We think so at least. Complete with a USB (Universal Serial Bus) charging cable, the Sound Sensitive Light Up Glasses will last for up to 12 hours, not even we've been to a rave that lasted longer than that. Sounds good.
