Biopact™ earplugs are custom made hearing protectors specifically developed to combat the noise associated with driving or riding at speed. Incorporating a special filter biased towards the harmful wind frequencies, Biopact™ cut no more sound than is necessary to protect the user.

Biopact™ are tailored to the individual from exact impressions taken of the users' ears allowing the production of comfortable, natural fitting earplugs that can be worn for long periods of time. The special attenuating filters are then fitted into the soft, durable, silicone earpieces. Biopact™ are manufactured so the user is provided with an earpiece that can be worn under the helmet without degrading the effectiveness through deformation of the ear canal.

Guaranteed levels of protection and comfort together with a lifetime of approximately five years the Biopact™ represents a long-term solution to the protection of one of the riders’ most valuable senses.

Biopact™ is independently tested to ISO4689 and DIN17460. They conform to European Normalisation EN352-2 standards laid down for hearing protection and carry the CE 121 marking.

Please Note : Extraction hoops shown in these images are an optional extra. For use in motorsport applications we usually apply a depression in the earplug to aid removal. If you require extraction hoops please specify this when you order. Can be provided with neck cord if required. Please note these neck cords are a device to retain the moulds and should NOT be tugged on to aid removal, as this can damage the moulds.
