The E-A-R Push-Ins earplugs feature an innovative, yet simple-to-use design which features the ultra-soft performance of a tip made of patented E-A-R form foam. The E-A-R form foam expands in the ear canal to create a comfortable seal against noise and provide an optimal hearing protection level. Plus, since the unique form actually softens and becomes more pliable with body temperature, the seal and comfort increases the longer the plugs are worn. E-A-R Plus-Ins stay seated with a gentle low pressure on the ear canal. E-A-R Push-Ins have a 28 Noise Reduction Rating (NRR 28db) and meet ANSI S3.19-1974 and CSA Z94.2 safety standards. Individually bagged earplugs with cords. View all of our E-A-R ear plugs.
