Question about Cobra 25 LTD 40-Channels Base CB Radio
Hello Darren, Yes it sounds like the mic is wired bass ackwards,,! A cobra 25 mic wiring is
PIN #1- Shield or ground wire
PIN#2- Audio or Transmit modulation
PIN #3- Transmit or Dead Key
PIN #4- Receive Audio.
When your keying the mic, the RX wires are being connected to make the RX work,,,
*** Let me know how you get along with it. Either buy a new mic wired for your radio or you or someone comfortable with soldering needs to resolder the correct wires back on the mic plug,,,Like I said, let me know and have a great day,, Mechanic is back quiet!

Check your ground wire and by your post I gather that you are user some form of headphone device, I say this because normally the speaker is off when the microphone is keyed. I would also check the controls on the headset if you are using one.
I hope this helps,
