The soft, smooth, tapered shape of the EARsoft earplug makes it extremely comfortable. The soft self-adjusting foam provides low pressure with excellent attenuation. The brilliant neon yellow color of the EARsoft Yellow Neons makes compliance checks easy. The EARsoft yellow neon blasts earplugs feature the same brilliant color, but are also decorated with exciting, blazing red flames. Also offered in a superfit version, which features a patented red ring that takes the guesswork out of proper fit. ANSI S3.19-1974/CSA Z94.2
