The Cobra GA-SM08 is a handheld speaker microphone (shoulder mic) for Cobra PMR two-way radios. It plugs into the radio's accessory socket so the radio can stay on a belt or in a pocket while you talk and listen through the mic clipped to a shoulder strap, collar or vest. It has a 36 mm, 1 W speaker, an electret microphone and a push-to-talk button, a rotating metal clip and a 3.5 mm earphone jack for a private earpiece. The housing is high-impact and water resistant, which makes it practical for outdoor work, security, events and vehicles. Check that your Cobra radio has the matching accessory jack before buying.
