The best of both worlds with the push of a button. Now workers can have excellent noise protection with an NRR of up to 26 dB when they need it. Plus the ability to hear speech and signals 'unmuffled' and safely amplified up to 87 dB when they want it. On and Off Simplicity. Push the button on the PTL earcup and it activates the listening mode for a 30 second interval. To terminate the mode before 30 seconds, just push the button. To activate another listening interval, push it again. No more muff lifting. To listen with standard ear muffs many workers lift their earcups or remove their muff completely. This exposes them to the dangerous noise. Limited exposure greatly decreases protection levels. When workers lift their muffs, they lower their protection. Now Peltor puts safe listening at their fingertips. With the touch of a button, hear co-workers more clearly. Comfortable earmuff in design and style. Available in:
