The Honeywell Sperian Bilsom 303L-10 Foam Earplugs are single-use polyurethane foam plugs for blocking noise on site, rated SLC80 22dB Class 4. That puts them in the range most crews need around plant, grinders, air tools and crane yards. Part of the 300 Series, they come in white and yellow, one size fits all, so there is no sizing to sort out before a shift.
Soft foam means they sit comfortably for long stretches, which matters when the plugs stay in all day rather than going in and out. Roll, insert, and let the foam expand to seal the ear canal. Being a single-use plug, you bin them at the end of the shift instead of washing and storing them. Handy for visitors, inductions and anyone who needs hearing protection on short notice.
