3M™ Peltor™ PTL™ Over-the-Head Earmuff

Over-the-head earmuffs listen-only headband headset offers attenuation with the push of a button.

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. Ear-cup button for listening mode. Listen-through capability with the pass-through sound limited to 87 dB. Auto-switches to full protection after 30 seconds or when button is pressed again. Ear-cups with liquid and foam-filled comfort cushions for long wear and optimum seal. Possible industries include: heavy equipment operators, airports, manufacturing, construction, agricultural, racing, oil rigs and petroleum refineries. NRR 26dB.
