Bose A20 HELP please

Hey guys, I’ve been using the A20s for flying and they’re amazing. One issue I’m having is that the intercom in my headset cuts off when I’m talking but my passengers and atc hear well and it doesn’t cut off for them. It’s annoying because I can’t tell if the mic is picking up my voice or not. I’ve tried adjusting squelch, volume etc but I still have that problem. Any suggestions would be greatly appreciated
