The soft, energy absorbing polymer foam is comfortable to wear and provides inner ear protection by reducing the sound levels to the ear drum - ideal for noisy site environments. The plugs can be inserted and removed with ease. This pack contains 6 x pairs of Scan Foam Ear Plugs in 3 handy re-sealable containers each with 2 pairs. The ear plugs have an SNR of 33dB and conform to EN352-2:2002.
