3M PELTOR PTL Earmuff, H7P3E-PTL, Hard Hat Mount Headset

The PTL HT listen-only hard hat model headset offers environmental listening with the push of a button. This comfortable and durable communications headset allows for long-term use under demanding conditions. The practice of "lifting off" an earmuff to hear can compromise attenuation and protection for wearers. 3M Peltor`s PTL earmuff helps resolve this problem by allowing "outside the muff" sounds to be heard clearly when needed. The PTL HT Series listen only hard hat mount model also features: Earcup button for listening mode Listen-through capabilitiy with the pass-through sound limited to 87 dB Auto-switches to full protection after 30 seconds or when button is pressed again
