Earasers were only introduced in 2012 but have taken the music world by storm. Their earplugs emulate custom-molded plugs at a fraction of the cost with all the same results.
Earasers protect our ears by decreasing audio peaks by up to 19dB. The thing that separates them from most earplugs is their design shape lets noise pass closer to the eardrum before being filtered, which makes the sound clearer without being muffled.
