To enhance low-level sound levels, the Impact Sport employs built-in microphones that amplify range commands and other important ambient sounds. Users enjoy full, clear directional sound in stereo.

For protection, the Impact Sport actively listens and automatically shuts off amplification whenever harmful sound levels are reached. The earmuffs effectively block any noise, continuous or impulse, of 82dB or higher.

As a low energy-consuming earmuff, the Impact Sport maintains a battery life of up to 350 hours. The automatic 4-hour shut-off feature helps to prevent excessive battery loss if the user forgets to turn the earmuff off.
