Description Stilo Rally Plus headset Headset with microphone. Dedicated to the Stilo TROPHY series helmets, this set is mounted as standard in the Trophy Des Plus series helmets (with WRC plug). The headphones can be used as a spare part in the event of damage to the headphones in the helmet, they can also be used to convert the Trophy Des Rally helmet to the Plus version, i.e. for an intercom compatible with WRC control units. A special intercom plug allows installation in a prepared hole on the side of the helmet.
