The ZeroNoise 6400012 is a 15 cm coiled adaptor with a female 4-pin Nexus socket at one end and a male 5-pin Nexus plug at the other.
ZeroNoise uses 4-pin Nexus for intercom helmets and amplifiers and 5-pin Nexus on the radio side. The female 4-pin end takes a male 4-pin plug, and the male 5-pin end goes into a 5-pin radio socket. An IMSA-wired version exists for American-wired kit.
The 6400013 does the same job with a male 4-pin end. Radio wiring varies between systems, so tell us the radio and the helmet and we will confirm the right lead before you order.
