Turn heads at dance clubs and parties when you wear our Sound Reactive LED Slotted Glasses. These super unique LED Sunglasses feature built in LEDs on the slotted lenses that "bounce" to the beat of music and sound around them. One size fits most. Each pair of LED Sound Activated Glasses comes with a micro USB cord to charge them. Choose from the sound reactive mode or an auto sensitivity mode that creates the perfect "bounce" of LEDs for any environment.
