Two Way Radio Mic

this feature comes on a Midland brand ( maybe others ) two way radio with a boom mic.

Probably voice activated mic mode.

Headset: two pin
Two way radio: has only 1 pin (it only accepts a special headset set)
But I was thinking that I could unscrew the radio and solder the speaker wire to the one connected the build in speaker and the microphone to the build in mic. Can someone tell me I this will work out?

It depends on the radio. Vehicle radios can be anywhere from 8 ohm to 50 ohm speaker outputs. Handhelds can be from 16 ohm to 600 ohm outputs. Most Motorola handhelds are about 16 ohm outputs to the headset or speaker mics.
Transmit audio is a different story. Many two way radios put DC voltage on the mic line for amplified mic elements. They take close to 1/2 volt audio. Others only take a few millivolts. If your add on mic way overdrives the radio you can try adding resistors in line till it sounds good. 10k ohm or so.
After all that, it's not going to sound very good. Computer mics are made to transmit up to 20khz. Most two way readios only handle 3khz audio and don't sound good if you try to cram high frequency audio down their throats. Computer mics tend to be way too sensitive and pick up a lot of background noise too.

Price: $79.99

VibraCall vibration alert or 20 different call tones
11 weather channels (7 NOAA) with alert features
iVOX hands-free communication without the need for an audio accessory
Pair of two-way radios with up to 35 mile range
22 channels each with 121 privacy codes for superior interference protection

Whenever I plug my Microphone/Earphone into the mic slot of my two way radios, it forces that radio in a transmit mode, so rather than waiting for me to push the button to communicate, it constantly transmits my voice. This wouldnt be a problem if it didnt block any incoming signals.

Any ideas how to fix this?
Its not a short, otherwise both radios wouldnt do it

Take it apart and see where the Push to talk circuit is shorting to another circuit and disconnect that.

Like in the movie "Shooter", they have one that looks like a bluetooth but the mic goes to your mouth?
I need one where I can talk to someone with one like it..but without using a cell phone..and without pressing a button to talk...just..when I say something, the person on the other end can hear me
