3M™ PELTOR™ PTL™ Earmuffs help provide hearing protection, yet allow temporary listening to outside voices and sounds without removing the headset. An earcup button with a Push to Listen (PTL) mode eliminates the practice of “lifting off” the headset when talking with or listening to another person. Simply press the earcup button to provide a 30-second boost in the volume of conversation and other sounds. Workers needing to talk over details of a job or receive instructions can keep the hearing protectors on. An auto-switch returns earmuffs to normal hearing protection mode after 30 seconds. The wide and liquid/foam filled earmuff cushions fit gently to help create a comfortable, noise-blocking seal. These hearing protectors are commonly worn in the following industries: agriculture, airport workers, construction, heavy equipment operators, manufacturing, petroleum refineries, and racing.
