Hear headset double?

I play on the ps4 and I have an Astro A20 and my friends always hear each other twice, but why have I fiddled a bit at the command center?

If they hear themselves twice you have feedback. Does your headset micro record what the speakers (headphones play). Adjusting the micro less sensitive should help.

You just can't change it for years and if someone knows how to get it away please tell us

Could you tell me where to do it, because I don't know me so well with these delicacies.

Should have a setting for it in the command center. Just take the manual.
