Pryme’s SYNERGY SPM-600 Original Equipment Manufacturer (OEM) -style speaker microphone. The SYNERGY SPM-600 is a solidly built version of a Radio Manufacturer speaker mic. This after-market speaker microphone is constructed of high-quality materials and includes the same great features as the OEM model, but at a fraction of the cost. The SYNERGY™ SPM-600 connects to single- and multi-pins, and comes equipped with a high-output speaker, high-impact water resistant polycarbonate housing, and a metal reinforced swivel clip. The rugged SYNERGY uses many of the same cables and parts as other Pryme speaker mics, includes the standard 3.5mm jack for multiple earphone options, and is backed by Pryme’s full 2-year limited warranty. Large orders (over 100 pieces) are eligible to receive optional custom printing of your company name, logo, etc.
