NoNoise Motorsport Hearing Protectors from Twisted Throttle contain precision tuned, ceramic filter technology, which offers protection from dangerous levels of engine, wind and road noise, but allows conversation, sirens and horns to remain clearly audible without the muffling effect of conventional earplugs. NoNoise filters are formed with a Venturi-shaped sound channel from high-grade ceramic material (zirconium oxide) at very high temperature so their internal aperture surface is perfectly smooth. They are silicone-free, hypoallergenic and have a Thermoplastic outer construction. NoNoise Hearing Protectors ($29.95 per set) come with an aluminum canister for safe storage, which can attach to your jacket or keys.
