The ZeroNoise Fearless WW ClearVoice (part 6100049) is the wired and wireless Fearless, and the top of the ZeroNoise range.
Wireless works with the Bell Mag-10 Carbon Rally WW and HP10 Evo-II Rally WW helmets and the ZeroNoise WW headset, up to about 20 metres, with up to two helmets and two headsets connected. Any other Nexus helmet works on the wired leads. A WW helmet battery lasts around four hours and tops up through the Nexus lead in the car; a flat helmet charges by USB-C. It has ClearVoice noise processing, Bluetooth, radio in and out, a camera output, CAN-bus, the ZeroNoise app and the same silicone keypad and display as the other ClearVoice amplifiers.
We supply it with two male leads, two female leads or one of each. Bell helmets have a female Nexus socket, so they take male leads. If you are not running WW helmets, the Fearless ClearVoice gives you the same wired performance.
Which helmets does this amplifier work with?
Wireless: the Bell Mag-10 Carbon Rally WW and HP10 Evo-II Rally WW and the ZeroNoise WW headset. Wired: any helmet with a 4-pin Nexus connection. Order male leads for a female Nexus socket (every Bell rally intercom helmet, the Sparco Flux RJ-i, Flux RJ-i Carbon and Prime RJ-i Supercarbon, and the OMP J-Rally) and female leads for a male Nexus plug (the ZeroNoise helmet kits, and Stilo WRC-type helmets through the Stilo AC0204.2 lead). For the earlier HP10 Carbon Rally WW, ask us before you rely on the wireless link.
What do I need for a complete working setup?
An amplifier like this one, a wired kit in each helmet, and the leads that join them. If you are starting from nothing, send us your helmet models and whether you want music, phone, or radio in the mix, and we will quote the full setup rather than leaving you to guess at parts.
Is it loud enough for a race car?
These systems are designed around exactly that problem: a straight-cut gearbox and open exhaust are why sound-deadened headsets and speech-focused amplification exist. Set microphone placement right against the lips and you will hold a conversation at full noise. If your car is unusually loud, ask us about the higher-output units.
