Thanks to their specially developed foam formula, these colourful, marble-effect Spark Plugs® earplugs offer the optimal combination of stability and softness. They are easy to roll and, upon insertion, expand to fill the ear canal at exactly the right time. There, they maintain a secure, sealed fit, without exerting pressure on the ear. Spark Plugs® offer high noise protection of 35dB (SNR).
