3M™ PELTOR™ PTL™ HT listen-only headband headset offers environmental listening with the push of a button. This comfortable and durable communications headset allows for long-term use under demanding conditions.

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.
