Separate mic and Headphones not working

Hi everyone,

I am super new to the world of audio and I have run in to a problem.

I have a scarlett 2i2 set up with a technica AT2020 as my mic in and my razer black shark V2 Pro wireless headset as the out put. I can record sound just fine using the mic but I cant hear it on playback through my headset. Ive been in to the audio hardware set up and check and definitely the correct headphones selected as the output.

This set up works perfectly in audacity but Audition doesn't seem to like something.

Any help would be greatly appreciated!
