The ZeroNoise 6400010 is a 50 cm coiled lead with a male 4-pin Nexus plug at one end and a 3.5 mm stereo jack at the other.
The male Nexus plug goes into a female Nexus socket, such as the one on a Bell rally intercom helmet, and the jack goes to a phone or other 3.5 mm device. It is the lead for using a Nexus helmet with a phone or a 3.5 mm audio source.
For a helmet kit or headset with a male Nexus plug, the 6400011 female Nexus to 3.5 mm lead is the matching version. The 3.5 mm jack does not fit the 6.35 mm sockets on the Valiant amplifier.
