Especially designed for professional and recreational shooters and hunters, Impact Sport's ultraslim earcup design features cut-outs for full clearance of firearm stock, eliminating interference while shooting. Hunter green earcups provide additional coverage when in the field, complementing most hunting apparel.
As safety on the range and in the field is most important, Impact Sport keeps wearers both protected from hazardous noise and connected to their environment. Impact Sport employs built-in directional microphones that amplify range commands and other ambient sounds to a safe 82 dB, providing more natural listening and enhances communication. For protection, Impact Sport actively listens and automatically shuts off amplification when ambient sound reaches 82 dB, effectively blocking out hazardous noise.
Enhanced Comfort Features
From its padded leatherette headband, compact folding design for convenient storage to its easy headband adjustment for a secure, non-slip fit, Impact Sport offers increased comfort, especially for long-term wear on the range or in the field. Optional earmuff belt case increases convenience of use.
Air Flow Control Technology
Bilsom Technology's patented Air Flow Control technology delivers optimal attenuation across all frequencies, without increasing earcup size orweight. A patented baseplate chamber and high-tech non-woven layer manage the flow of air inside the earmuff to control how sound reaches the ear. The result is better, more consistent overall attenuation for virtually all industrial noise environments.
