This system has 2x speakers, microphone and all connected to outgoing STILO integrated female socket.
This kit fits only with STILO helmet models - Venti Trophy or Trophy Des.

Most common use in disciplines where communication is happening mostly between races or during the race in the car where hearing the outside engine noise is mandatory due to fact that speakers do not have earmuffs. Thus most of the engine and outside noises are still heard.

Outgoing socket: Audio female.
Compatible with audio jack connectors (see picture ) for radio communication systems or Rally amplifiers with 6.35 mm audio connectors.
Shaft diameter: 6.35 mm

WARNING: This item is not compatible with WRC/Nexus type sockets/connectors (7.1 mm). See picture .
