Hi guys.
I accidentally messed up one of the nozzle filters on my KZ Castor Pro Bass, so I'm looking for replacements. I've seen steel mesh and fabric filters on AliExpress, but I'm not sure which material matches the original sound profile best.
Additionally, does anyone know the exact diameter for the Castor? Should I buy 5.0mm, 5.5mm, or a different size?
Appreciate any help!!
