Raiju ps4 controller mic picking up headphones sound

So I'm having an issue recently where the mic is transmitting headphone sound in chat, ie when I fire everyone hears the bang. It's a recent issue, only started a few days ago. Its not the headset as it doesn't do it with the standard ps4 Controller (just tested) and I tried with a different cable and there was no change so the cable is fine. Any ideas?
