Want more power? Our Pulse Pro premium speakers deliver the ultimate audio experience available for audiophiles who also happen to ride. Our tuned 40mm drivers boast the cleanest bass and truest mids in the industry- PERIOD. Tiny BOOMELSS dual mics hide under the liner (above the eyes or behind cheek pads) to improve voice transmission quality. Drop them into any full face, modular, ¾ or off-road helmet and turn up the thump!
