When you ride a motorbike, drive a car or kart you will always face engine and wind sounds under the helmet. Measurements under a motorbike helmet showed the following results:

Speed / Wind sound / max Time of Sound Stress

• 100 km/h / 94 dB / 15 minutes
• 120 km/h / 98 dB / 7 minutes
• 140 km/h / 102 dB / 3 minutes

Especially suitable for people who wear helmets: MotoSafe II, a very soft and reusable plug. It offers good sound quality and ventilation and comes with two different pairs of filters.

Since Bilsom 303 and ColorPlux fit deeply in your ear they are perfect for wearing under a helmet. We also recommend Mack's Plugs with its soft special-silicone. MultiPlux are reusable.
