Product source ↗The KEP-28-S is a speaker microphone with IP54 protection and a straight standard Icom two-pin connector. Its 45 mm speaker provides open audio, while a 3.5 mm socket accepts a separate earphone. A stainless-steel clip attaches the unit to clothing or carrying equipment.
K-PO publishes both microphone and speaker specifications and includes the President Randy III in its compatibility list. This collection pairs it with the Randy III+ setup. The S suffix matters: other connector versions of the same microphone are not automatically interchangeable.
