The Entel EA19/DX is a ‘D’ shaped, soft rubber-feel earpiece which fits over your ear. The earpiece is combined with a lightweight short profile boom microphone. There is an in-line press to talk button (PTT) with clip. It allows the radio user to carry the radio on their belt and have the facility to both make and receive calls without removing their radio. This keeps the radio safe and ensures that calls are not missed, especially in noisy environments. This accessory is designed for light to medium duty applications, so to ensure maximum life span it should be personally allocated to users.
