Yaesu vx7r radio connect to Kenwood headset

Hi everybody :slight_smile:

I have a yaesu vx 7-r with a ct-91 wire outlet for headset.

I have bought some durable headset that are ment for Kenwood radio(th-22)

The outlet from this headset have a 3.5mm jack and a 2.5mm jack.

When I connect this to the ct-91 outlet from the radio nothing is working…
no sound,no PTT-function.

Anyone could help me make an transistion wiring?
