I get that this is something you just hit record on while chatting on a work laptop or something, but the 's' sounds in your audio track especially are so high pitched it's unbearable to listen to for me.
I will say that this recording does sound better than a much earlier one I tried a while back. So if you did change your mic at some point, it probably helped quite a bit.
I just listened to the first couple minutes, but generally quite a few of your 's' sounds trigger the nails on chalkboard type reaction(not that bad though, but same type of reaction). Hope this makes sense to you. Im a couple decades younger than you, so could be I'm hearing some high frequencies you couldn't hear.
Keep up the great work at Oxide!
The old “pencil trick” can be highly effective, even with good mics: https://urm.academy/death-to-sibilance/
