The soft polyurethane foam has a unique cellular structure that allows for slow expansion to perfectly fit the size and form of the ear canal, with a sealed surface that prevents foreign bodies from penetrating. The material provides high and immediate noise reduction.

Uncorded: The most economical option, and mainly for one time use. Also practical in areas where a cord may be hazardous.

Tapered: Fits to the natural contour of the ear canal.

Features:

• Innovative “T-shape” makes removal simple
• NRR 32 protection
• 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 long term comfort

Understanding the Noise Reduction Rating.

The level of noise entering a person’s ear, when hearing protection is worn as directed, is closely approximated by the difference between the A-weighted environmental level and the NRR.

Example

1. The environmental noise level at the ear is 92 dB(A)
2. The NRR is 32 decibels (dB)
3. The level of noise entering the ear is approximately equal to 60 dB(A)
