Pro-Ears Pro Mag Gold Hearing Protection Headset is the balance achieved between comfort, noise attenuation and purity of sound. The engineers at Pro-Ears have developed a hybrid digital/analog system found exclusively in these Gold Series active hearing protectors. To further enhance the natural sound quality, gold connectors are used on these Pro-Ears hearing protection devices, along with high quality amplifiers and microphones to reduce impedance. Advancements in DLSC technology for compression turn an impulse sound wave from a gunshot into a soft, audible pop in the ProEars Pro Mag Gold NRR 33 Electronic Ear Muffs. Finely engineered circuitry with proprietary programming has reduced attack time to 1.5 milliseconds.
