These are the visually harmonizing glasses that bring a rousing rhythmic light show to a prosaic party. Available only from Hammacher Schlemmer, the glasses have built-in audio sensors that detect the beat of music and synchronize 12 multi-color LEDs—six on each lens—to illuminate the louvers from the bottom up like a digital volume unit meter, producing a visual symphony of colored light. Ideal for concert goers and sufficiently hip parents, these glasses inject amusing merriment into any occasion or social soiree. The one-way LEDs keep light out of the wearer’s eyes, enabling the celebrant to enjoy themselves with an unobstructed view. These glasses allow 24 hours of grooving fun from a full charge using the included USB power adapter. One size fits most. Ages 12 and up. 2 1/4" H x 6 1/4" W x 6 1/2" D. (8 oz.)
