The EarPro EP500 from Surefire is a high-quality communication system designed for Motorola and Nextel phones, and most other phones that have a 2.5mm jack. This two-wire, single cable system features a lightweight electronic ear coil with an in-line weatherproof speaker constructed from aerospace-grade aluminum that delivers a broad range of frequencies for ultimate sound clarity.
The system's cable is shielded to reduce radio and electromagnetic interference. It is wrapped in Kevlar and jacketed with thermoplastic urethane to resist extreme temperatures, flex fatigue, chemicals, and abrasions. The omnidirectional microphone has an integrated windscreen and is encased in a submersible aluminum pod to resist shock and provide professional-quality audio.
Incoming audio is channeled directly into your ear via a medical-grade Tygothane dry sound tube that is specially tuned for vocal clarity and designed to release condensation moisture. A comfortable EP1 CommEar Comfort earpiece reduces the risk of people overhearing your communications. The sleek earpiece can be worn under a hat, helmet, or mask, and doesn't block out ambient noise.
