Which In-Helmet Radio Headset Fits A Bell R7 Sport Or Other FIA 8859 Helmet?
A customer asked us which in-helmet radio headset, with a Nexus or matching plug, goes into an FIA 8859 helmet like the Bell R7 Sport for use with a one-way radio. The helmet is listed with no communication included, so the headset is a separate part. Our Nexus full face headsets start at £75.60, and the radio end decides the rest.

A ZeroNoise full face Nexus headset, then the right lead for your radio
£75.60inc VAT
The helmet end is the easy half. Tell us the radio and we confirm the other end before you order.
- The Bell R7 Sport is listed FIA 8859-2024 with communication not included, so nothing is fitted in the shell.
- ZeroNoise full face headsets from £75.60 end in a male 4-pin Nexus plug and fit behind the helmet lining.
- The radio end is what varies: the headset plugs into an amplifier with female Nexus leads, or into a lead made for your radio.
- Tell us the helmet and the radio model and we spec the parts that work together.
What the Bell R7 Sport comes with
The R7 Sport is a composite full face helmet with FIA 8859-2024 homologation, in white or matt black and in sizes S to XL. The listing shows the Communication option as Not Included. That means the shell has no speakers or microphone fitted and no Nexus socket, so any headset goes in afterwards.
It comes with HANS posts or without, depending on the variant you pick, and our earlier posts compare it with the GP3 it replaces, so here we’ll stick to the radio.

Nexus full face headsets that go behind the lining
Nexus is the four-pin connector most rally and race intercom kit uses. The ZeroNoise full face headsets below each end in a male 4-pin Nexus plug, which the listings say suits a ZeroNoise Brave, Fury, Fearless or Pit-Link with female leads, or any amplifier with female Nexus leads. The speakers sit in the ear recesses of the helmet and the microphone sits in the chin bar area.
Check what’s on the other end before you pick one: a male plug needs a female socket, and the headset listing won’t tell you what your radio has.
| Headset | Speakers | Microphone | Plug |
|---|---|---|---|
| ZeroNoise Full Face Helmet Intercom Headset | Flat speaker pads | Chin bar, noise cancelling | Male 4-pin Nexus |
| ZeroNoise Full Face Helmet Intercom Headset With Integral Ear Cups | Speakers inside foam ear cups | Chin bar | Male 4-pin Nexus |
| ZeroNoise Pit-Link Microphone Helmet Kit | Earplug socket, earplugs sold separately | Dynamic noise cancelling, inside the helmet | Male 4-pin or 5-pin Nexus |
Read from the product listings. Prices are in the sections below.
This is the plain version. The speaker pads are flat, they locate in the ear recesses behind the lining, and the listing describes the microphone as dynamic noise cancelling. The cable ends in a male 4-pin Nexus plug.
Garreth’s tip for a club car is this one, because it costs £75.60 and fits behind the lining of most full face shells without a fuss.

- Flat speaker pads
- Chin bar microphone
- Male 4-pin Nexus plug, part 6300010
The speakers here sit inside foam ear cups that fit into the ear recesses of the helmet. The listing says that isolates the speakers from cockpit noise better than flat pads, so the amplifier does less work and the voice is clearer in a loud car. The plug is the same male 4-pin Nexus.
The listing is also clear that helmets with defined ear cup recesses in the lining take it cleanly, while a flat lining suits the flat pad headset better. It costs £121.20 more than the flat pad version. Garreth’s tip is that it is worth paying for in a loud car, and Cameron will check the helmet against it before you order.
- £196.80 inc VAT
- Foam ear cups
- Chin bar microphone
- Male 4-pin Nexus plug, part 6300009
This one is a microphone only. It fits a dynamic noise cancelling microphone inside a full face helmet, with foam spacers to set the distance from your mouth, and adds a socket for earplug speakers. The listing says it is for car-to-pit radio and the Pit-Link system. The earplugs are sold separately, with an RCA or 3.5 mm connection.
It comes with a male 4-pin Nexus plug, or a 5-pin one for radio systems with a 5-pin socket, and that choice is the reason to ring us before ordering.

Connecting the headset to a one-way radio
Radios are the part we cannot answer from a headset page. Handheld radios use their own plugs, and the headset has a Nexus plug, so something has to sit between them. That is either an amplifier with Nexus leads or a lead made for your radio.
The ZeroNoise Pit-Link ClearVoice Bluetooth Amplifier lists a 3.5 mm radio in and out, with 4-pin Nexus leads in the gender you choose. A male lead plugs into a female Nexus socket and a female lead takes a male Nexus plug, which is what the headsets above carry. For radios with a 5-pin Nexus socket there are ZeroNoise 4-pin to 5-pin adaptor leads, and Stilo list radio cables for named Motorola, Kenwood, ICOM and Vertex handhelds with a universal option.

We haven’t got a listing that says what a one-way radio needs differently from a two-way one, so we don’t want to guess. Tell us how you use the radio, listening only or talking back, and we’ll say which parts matter. For the timing of any of these, the product page has an Availability tab and an FAQ.
Other FIA 8859 helmets
The same logic holds for any FIA 8859 full face helmet that has no communication fitted: the headset goes behind the lining and its plug has to meet the radio end. Helmets with Nexus built in, like the Bell rally intercom helmets, are the other way round, because they have a female Nexus socket and take a male lead from the amplifier. Stilo helmets have their own pairings.
We have a full compatibility guide for those, Which Stilo helmets work with which Stilo intercoms, and for anything else, send us the helmet name and size and Cameron will tell you which headset goes with that shell.
Common questions
Does the Bell R7 Sport have a Nexus socket built in?
No. The listing shows Communication as Not Included, so the helmet comes without speakers, microphone or socket, and you add a headset.
Which plug do the ZeroNoise full face headsets have?
The two full face intercom headsets, at £75.60 and £196.80, end in a male 4-pin Nexus plug. The Valiant full face headset at £36.00 ends in a 6.35 mm jack instead.
Will the headset fit the ear recesses of the R7 Sport?
Our listings do not say how the R7 Sport lining is shaped around the ears. The flat pad headset suits most full face shells, and the ear cup version suits helmets with defined recesses. Tell us you have the R7 Sport and Cameron checks it before you order.
Which headset would you start with for an R7 Sport?
Garreth’s tip is to start with the £75.60 flat pad headset and keep the ear cup version for a loud car. The radio lead matters more than the headset, so send us the radio model first.
Can I plug the headset straight into a radio?
Not usually, because the headset has a Nexus plug and handheld radios use their own. You need an amplifier with Nexus leads or a lead made for the radio. Send us the radio model and we will say which.
What is the difference between 4-pin and 5-pin Nexus?
It is the number of pins in the plug. The Pit-Link microphone kit comes in both, and ZeroNoise make adaptor leads between the two. Tell us the socket on your radio system and we confirm which you need.
Do I need a headset for both the driver and a co-driver?
An amplifier is a two-seat unit, and each person needs their own headset or helmet connection. For a one-way radio to a single driver, tell us how it will be used and we spec it.
What we would buy
Garreth
Garreth's top tip
For an R7 Sport I'd take the ZeroNoise Full Face Helmet Intercom Headset at £75.60. It has the Nexus plug, it fits behind the lining, and it leaves money for the radio lead.
If the car is loud, the ear cup version at £196.80 is where I'd spend more.
Cameron
Cameron's fitting view
I'd sort the radio end before the headset. Get me the radio model and whether the socket is 4-pin or 5-pin, and the headset is easy to match.
On the ear cups, the headset wants defined recesses in the lining, so I'll check the R7 Sport against it before anyone pays £196.80.
Not sure which plug your radio needs?
Tell us the helmet, the radio make and model, and how you use it. Cally, our digital receptionist, takes your details. Cameron comes back to you with the parts that fit together before you order.
