With up to 24 dB noise reduction, the Pinlock® earplugs protect you against helmet-generated noise by reducing it to safe levels, yet still allowing conversation,
sirens and sounds to be clearly heard. Other hearing protection can sound muffled and unnatural while the Pinlock® earplugs provide full frequency noise reduction.
The Pinlock® earplugs are silicone free and designed to avoid interference with the helmet inner-liner.
