Unique Push-to-Fit design provides excellent decibel-reduction performance with a clean and comfortable wearing experience. Flexible-fit stem allows the wearer to insert the plugs without touching the plug tips, keeping the tips and the user's ears clean, even when the user's fingers or gloves aren't. Soft and smooth, no-roll, slow-recovery E-A-Rform tips slide into place easily, compressing as they're inserted and slowly expanding once in place, ensuring a snug and secure fit. Compatible with the 3M E-A-Rfit Validation System.
