Is this normal? I’ve tried my old apple earpods and Meze 99 classics, I can hear the same hissing noise on both. Changing volume levels does not affect the noise levels. I’ve looked at other posts on the same topic but couldn’t find if this is normal or not.

I already have a dead subpixel that I was overlooking, maybe this in combination now warrants a RMA?
