While wearing the x-62000 from Xacore's Threat4 line, you can protect your ears from gunfire, explosions, and loud engine noise, but still have a face-to-face conversation while maintaining radio communications. The x-62000 second generation in-ear digital radio headset is what Xacore calls a hybrid headset, melding the best features of an in-ear headset design with the best features of a typical over-the-ear muff-style headset. The x-62000 is compatible with most commercial and military radios on the market.
