This compact, high-shock resistant heavy-duty speaker microphone is constructed with sturdy polycarbonate polymer and is water resistant. It provides for extended durability and usage in most active job applications, where the user is typically prone to personal contact interruptions, dropping & pulling, and heavily persistent usage during two-way radio communications. Designed to be worn on the user's lapel, duty belt, or shoulder epaulet, the heavy-duty speaker microphone can be secured by a versatile, rotatable 360 degree metal-reinforced fastening clip. Reconik's heavy-duty speaker microphone features a small yet powerful built-in speaker that produces ultimate audio clarity with noise canceling. The heavy-duty speaker also features an excellent Knowles microphone, which provides for loud and clear audio reception in noisy environments.
