This hands free CB microphone system from Cobra is a great idea for any 4 pin radio. When connected to your radio, this mic alows you to talk through a remote headset keyed from a remot PTT button. The PTT button is separate from the headset, so I can be placed close to your hand ( on the steering wheel, shifter, ect.). Both components connect to a powered junction box that plugs into any 4 pin CB radio. The junction box requires a 12 volt connection.

great product. I operate heavy equipment and it is a great way to keep my hands where they are suppose to be.
This a great item. I am putting it on a motorcycle and it will be a great fit. My only regret is that it did not have a ear speaker, thus I am going to have to attach an additional ear bud system for that issue. Thanks
Order received, happy with what we asked for, thank you.
