Baofeng headset adapter

Not being content with the painful to wear headset my friend received with their baofeng uv-5r radio, they asked me to make an adapter to use regular headphones with it.

I went one step further for them and included support for headphones with microphone, and PTT button.

This is the working prototype, have to tidy it up a little, and mount things nicely in a box.

It break out to two 3.5mm sockets, one for speakers and one for mic. From there I’m using a spare adapter I had that turns the two separate sockets into a single 4-pole socket!

This let’s you use 4-pole earphones with mic

The volume is crazy loud at the moment so I’ll have to add in a resistor. And nothing is soldered yet, just twisted in, Hehe. I’m in a train (y)

Anyway, I can’t test the mic yet, but the PTT button does work. Not sure where it would be most convenient yet

I’ll figure something out. For now enjoy these images :
