Low-pressure, foam earplugs are ideal for long-term users and those with small ear canals. Pre-shaped, contoured T-shape allows easy insertion and removal. Low-pressure polyurethane foam expands gently for comfortable long-term wear. Smooth, soil-resistant, closed cell-foam skin prevents dirt buildup. Earplugs are corded and offer a Noise Reduction Rating (NRR) of 30.
