3M 318-1005 E-A-R Push-Ins Foam Earplugs, Corded DUWQW_DW814

Product details:

No roll down Earplugs. Plus, since the unique foam actually softens and becomes more pliable with body temperature, the seal and comfort increases the longer the plugs are worn. The patented E-A-Rform foam tip is shaped and sized to mold comfortably to fit virtually every sized canal.
