The GF Series is the ideal entry point into professional motorsport communications. Designed for drivers, riders, mechanics and race teams who need reliable communication without the cost of a custom-moulded solution, the GF Series combines effective hearing protection, excellent audio clarity and robust construction in a convenient off-the-shelf package.

Unlike custom communication earpieces, the GF Series requires no ear impressions and can be used immediately. Supplied with four pairs of replaceable foam tips, it provides a comfortable and secure fit while helping to reduce background noise from engines, wind and the surrounding environment. This allows critical team communications to be heard more clearly while improving overall comfort during long periods of use.

At the heart of the GF Series is a high-quality balanced armature speaker selected specifically for its ability to reproduce detailed and intelligible audio. Whether receiving race strategy updates, pit instructions or safety information, users benefit from clear communication even in demanding motorsport environments. The combination of noise reduction and detailed sound reproduction ensures important messages are delivered with clarity when it matters most.

Built specifically for motorsport applications, the GF Series features a polyurethane-coated cable designed to resist sweat and environmental degradation. Internally, Kevlar-reinforced strands and Ultimate Ear's proven four-point anchor system provide additional strength and durability, helping to ensure long-term reliability in challenging racing conditions.

The GF Series is available with a choice of RCA, Stilo helmet and 3.5mm connectors, making it compatible with a wide range of motorsport communication systems. Users can also choose their preferred cable length to create a solution tailored to their individual requirements.

Whether you're a track day enthusiast, club racer, rally competitor or professional race team looking for a dependable backup solution, the GF Series delivers excellent communication performance, practical hearing protection and outstanding value for money.

Cable and Connector Specifications

This product is supplied with the choice of an RCA (Phono), 3.5mm (Mono) or Stilo helmet connector. The Stilo helmet connector is a LEMO FFA.00.250.CTAC29 push-pull connector, allowing direct connection into the Stilo ST4 or ST5 helmets. We can also manufacture this product with other specialist connectors for Motorsports, please get in touch with us to discuss your requirements.

Our cables are polyurethane coated which stops the cable reacting to sweat (causing it to go brittle). Kevlar coated strands makes our cable extremely durable and we also utilise a four-point anchor system for added strength. The cable exit is correct out of the earplugs, preventing any snagging issues.

Our standard cable length is 50cm, and this is the total length from the earpiece to the connector. Custom lengths are also available.
