The ZeroNoise open-face helmet headset with integral ear cups (part 6300004) is an in-helmet headset for open-face motorsport helmets, built with the speakers mounted inside foam earcups, not flat pads.
The foam earcups fit into the ear recesses of the helmet and provide stronger sound isolation than flat speaker pads. In a noisy cockpit, particularly rally or off-road use where background noise is constant, the physical isolation from the cups helps the amplifier deliver cleaner audio to both crew. The microphone is on a flexible boom arm, adjustable to sit close to the mouth regardless of helmet fit. The cable ends in a male 4-pin Nexus plug, for a ZeroNoise Brave, Fury, Fearless or Pit-Link with female leads, or any amplifier with female Nexus leads.
The ear cups are the difference from the flat-pad open face headset. If your helmet has shallow ear recesses or a flat lining, the standard open-face intercom headset will fit and perform well. The 6300004 is specifically for helmets built around earcup recesses where the foam cups can locate properly.
It fits the Sparco Flux RJ well. Remove the helmet’s original ear foams and fit the ZeroNoise cups in their place; they locate in the same recesses. For the microphone boom, route it under the helmet lining using the components included in the kit rather than under the side cover panel, where the clearance is tight.
