This is a direct replacement to WRC electronics as fitted in the Trophy Plus helmet. Coming with large speakers fitted inside the padded earcups, the metal spiral microphone boom, and the screw-in intercom socket all of which will improve the quality of sound through the intercom.
These electronics allow a Trophy Jet or Trophy Rally helmet to be upgraded to the superior WRC electronics. The WRC electronics utilise Stilo's Nexus jack for superior audio quality, and can only be connected to the WRC 03, WRC 9V, DG10 and DG30 intercoms. It can also connect to other brands of intercoms using one of Stilo's range of conversion cables.
