I fucked up my IEMs by cleaning them with alcohol :(
It softened the glue that held the mesh inside the soundy thingamajig and made them sound funny so I removed the mesh altogether.
I thought was just for earwax not to go into them... turns out it's actually filtering some of the highs so they aren't as sharp and spiky.
I could use these with a flat eq but now I have to tinker with it
