Apeman A79 help

[chriaj383]

Hi It’s my first time posting here so hopefully this is in the right category.

I have an apeman a79 with a 2.5mm mic port, the original mic that comes with it has one black band on the male end. I also have a synco G1 A1 wireless lavalier microphone which has a 3.5mm mic port, so I bought a TRS 2.5mm male to TRS 3.5mm male cable but when ever I’m recording videos on the action camera it’s just using the inbuilt microphone and not the wireless microphone.

Would anyone know which cable I would need for the wireless lavalier microphone to work.

Thanks,
Chris
