OFFROAD Car Harness to 3.5mm Stereo Ear Piece Adapter enables direct connection to STEREO earbuds via your OFFROAD interface, offering convenience for listen-only applications, passengers, and some racing environments. However, it's incompatible with MONO earbuds. Noteworthy is the Dura-Link Seal, a molded design element that establishes a sealed connection between the intercom cable and helmet kit plug for protection against water, mud, and dirt that might impair audio performance. The Dura-Link Seal is compatible with both current Rugged OFFROAD intercom cables and all Rugged OFFROAD helmet kits. Adapter is designed exclusively for STEREO earbuds.
