PowerSoft™ Foam Technology is a proprietary polyurethane foam formulation that results in ear plugs with optimally-sized cell structure that expand gently and evenly inside the ear canal. This translates to all-day comfort with exceptional attenuation.

• Consistent cellular structure for optimal expansion recovery time for a custom, uniform fit
• Smooth closed cell outer layer that prevents debris build-up
• Soft and comfortable PowerSoft™ foam supports all day comfort
• NRR 33 protection
