HS001 Speaker Mic Kit Included (IP55)

Every radio in this 50-pack ships with the HS001 1-pin 2.5mm shoulder speaker mic. Clip it to a collar or vest strap and the large speaker keeps calls audible over saws and generators. The IP55 mic handles drizzle and dust while the radio stays holstered.

VOX Hands-Free Operation (0-9 Levels)
