3M PELTOR EARMUFF H7A-PTL

When workers lift their ear muffs, they lower their protection. Now Peltor puts safe listening at their fingertips. Just push the button on the PTL muff and speech and sounds "outside" the muff cup can be heard "inside" clearly and safely. After 30 seconds, the muff automatically returns to its full protection with a NRR of up to 26 dB. Listen again? Just push again. That simple.

GREAT for race car crews and ground crews at airports.
