I remember the metallic. Not a fan either. It put me massively on edge for a long time. Ask @Chinmoku he knows. I will argue I may have one of the most fluctuating T's on this forum, but the metallic sound disappeared eventually. I pray it will for you too.

Same thing happening with me, is driving me crazy.
You could try some hearing aids/maskers. Audicus is a good online one. They have really good customer service. Someone on this forum referenced them on a post. They have a new line up since I bought mine. They now have lithium rechargeable models with Bluetooth.
Metallic piercing reactivity yup got it
Is so unfrair, during day I can go by but at night seems I hear the hiss and morse code on the other ear, but that morse code goes to full EEEEE very very loud and is like painful.
@ErikaS, you could try the Shulman protocol and take .5mg Clonazepam plus 300mg Gabapentin twice a day. That's what I'm back on after a Zoom session this week with a psychiatrist.
