The unique digital sound circuit eliminates the sharp sound clip that is typical for most level dependent hearing protectors on the market. Many people find that sound unpleasant and disturbing. The new electronics in the Peltor™ SportTac™ hearing protector react instantaneously, protecting your hearing from loud impulse noises. The system reacts so gently that you rarely hear the clip as the protection is activated. Just like the other level dependent hearing protectors from 3M, the SportTac hearing protector also enhances your hearing, so you actually hear better with the hearing protector than without it. The Peltor™ SportTac™ also allows you to connect your hunting radio directly to the headset.
