The Motocomm Thumper2 stereo
helmet speakers are designed to easily attach inside any helmet that covers the ears. This includes ski helmets, snowboard helmets, motorcycle helmets, MX helmets, snowmobile helmets, skate helmets, and some bicycle and mountain bike helmets. The 1-1/2 inch diameter stereo speakers provide excellent sound quality and the
loudness required even when riding a motorcycle. The speakers are easily mounted with included velcro and come with cushion covers for comfort against your ears. Heavy duty wiring, weatherproof connections, and a lower
coiled cable are designed to make for easy use no matter what device you are connecting and where you are keeping it. The Thumper2 connects directly to any standard 3.5mm stereo headphones jack on your
smartphone, music player or other portable device. For situations requiring max
volume, the Thumper2 speakers will handle the use of external headphone
amplifiers.
