Earasers Musicians Earplugs, Medium 19 db Flat Frequency Noise Reduction Whether you are a musician, attend concerts or are regularly exposed to music played at high levels, Earasers don't plug up your ears and muffle sound like more conventional earplugs. Manufactured by a 50 year old hearing aid company, and developed by their lead engineer - a musician for over 20 years - Earasers filter out loud noise while still allowing you to hear at a safe, comfortable level. Musicians have to be able to focus on the different layers of instrumentation. Earasers utilize a unique attenuation "V filter" to provide up to 19dB of protection in the frequencies you need it most. The result is the world's first flat frequency response earplugs. The Earasers soft silicone design is based on one of the most widely used hearing aid tips in the market. There is no need for expensive trips to a specialist to get custom ear molds. The Smart Seal technology conforms to the shape of your ear canal for a more comfortable fit that you can wear all day. Earasers can be cleaned and reused, and when the silicone tip starts to get old, they can be "Renewed" with new silicone sleeves. Regardless of the type of musician you are, even singers love Earasers.
