Digital audio. Anyone found a solution with testing different speakers and EQ?

It's been 16 months with one setback and I'm going crazy without any digital noise stimulation.

I can't use any digital sources like speakers etc, I get instant pain from it.

I was thinking of trying buying different speakers and using EQ. Has anyone tried this?

For me cheap monitor speakers worked for a while, till my setback.. Now even that causes an issue. I'm tired of waiting.
