Extreme bass and clean sound for those who want a premium wired helmet speaker that plugs into their audio source with a 3.5mm jack. Also serves as a speaker upgrade for most competing comm systems with 3.5mm jacks. The 3’ extension allows it to reach from your helmet to your device, but breaks away easily when you remove your helmet or need a shorter cord for use with competitors’ comm systems. Not for use with UCLEAR comm systems. Gold plated 3.5mm jack, 40mm tuned driver, 3' extension cord, universal fitment.
