ProCase Soundproof Earmuffs, Olive Green, Model EM7003-1, perfect for hearing protection. I only used these a few times over a period of one to two months because of the noisy construction of a new house in front of my home. They are in good condition, but they are not new, so please be aware of this. In terms of soundproofing, they are comparable to earmuffs from a famous manufacturer. - Brand: ProCase - Model: EM7003-1 - Color: Olive Green - Quantity: 1 - Application: Soundproofing, Hearing Protection - NRR 30dB Thank you for looking.
