Following the success of our award-winning dual-filtered HearDefenders-DF™ we have recently been asked to create an ear protector that could be filtered or non-filtered.
With our new PopStoppers™, the end user can leave the "Stopper" in the OPEN position to hear critical environmental sounds and in the CLOSED position when additional at- tenuation is desired. (See photo, right).
The process is simple and it really works!
PopStoppers™ can be used with both Lab Molds or Insta-Molds.
- Open Position: NRR - 19 - 20 dB.
- Closed Position: NRR 30 - 31 dB.
It is like having BIFOCALS for hearing protection!
