The G Series Motorsport has been developed for drivers, co-drivers, engineers and race teams looking for a professional communications solution without the need for custom ear impressions. Combining Ultimate Ear's extensive knowledge of the human ear and experience in motorsport hearing protection, the semi-custom design of the G Series offers outstanding comfort, reliable communications and effective noise reduction in a convenient off-the-shelf format.

Unlike traditional foam earpieces, the G Series has been designed around the natural contours of the ear. Available in three carefully engineered sizes (Small, Medium and Large), the semi-custom fit provides excellent stability and comfort during long races, track days and endurance events. This ergonomic design helps reduce environmental noise while ensuring the earpieces remain securely in place under helmets.

At the heart of the G Series is a premium balanced armature speaker chosen specifically for its ability to reproduce clear, detailed audio. Whether receiving race strategy updates, safety information or team communications, the G Series delivers excellent speech intelligibility even in high-noise motorsport environments. The combination of effective isolation and precise audio reproduction allows drivers to hear critical information clearly while maintaining focus on the track.

Built specifically for motorsport applications, the G Series features a robust polyurethane-coated cable designed to resist sweat and environmental degradation. Internally, Kevlar-coated reinforcement strands and Ultimate Ear's four-point anchor system provide exceptional strength and reliability, reducing the risk of cable failure in demanding racing conditions.

The G Series is available with a choice of RCA, Stilo helmet and 3.5mm connections, making it compatible with a wide range of professional and amateur motorsport communication systems. Users can also select their preferred cable length to create a more bespoke setup.

For drivers who want a comfortable, durable and high-performing alternative to generic foam earpieces, the G Series Motorsport delivers professional-level communication performance at an accessible price point. It is the ideal choice for track day enthusiasts, club racers, rally competitors and professional race teams alike.

Material

These earplugs utilise a 40-shore silicone for a combination of comfort and adequate strength in order to protect and secure the main components within the earplugs.

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.
