well it looks like ety finally discontinued the ER38-50E filters. does anyone know the acoustic resistance of these?
i'm probably going to have to find another source but would like to match the resistance if possible.
it's these little white ones. for the er6i, er22 & i believe the old (red/blue) version of the er4
