How do I monitor my own voice in my headphones while transmitting?

Len AC1BP

I have a RadioSport over-the-ear headset connected to my Flex 6300 using both the MIC and PHONES jacks. It works fine in that others can hear me and I can hear others, but I can't hear myself while transmitting. Interestingly, I can hear my CW transmissions in the headset. Just not voice. 

Years ago, I spent some time behind a microphone at a radio station. I wore a headset and I could hear myself (and everyone else) clearly through the headset. Now I feel like a deaf person when I'm talking. I almost have to guess what I sound like as I'm taking. 

I feel like there must be a simple button, slider or setting that I just don't know about.

 Try the mon button in the panel, the same panel that your mic gain is in. It also has a volume control so you can adjust your monitor audio.
