Do the voices sound "raspy"? Is this just a things with lower end canalphones? They just don't sound smooth...

The Marshmallows make my AKG K 81 DJ sound very cold and harsh.
Yeah I think they have some harsh resonances in the upper mids, that is a characteristic of the raw driver. The paper filter, attenuates the upper mids... and this makes the resonances harder to detect.

one thing I have noticed with dynamic headphone drivers: If the drivers have resonant characteristics in the upper mids, adding foam sheets or perforated paper filters in front of the drivers does NOT clear up the resonance. Rather, it transforms those harsh resonances into muddy/congestion.

So... this mod helps to a certain extent to brighten up the overall sound. But, the drivers will always kind of have that signature sound.

It won't transform them into magic KSC75 slayers... but its still a step in the right direction IMHO.
