Well a found a way to reduce the upper mid harshness to comfortable levels, but it’s not a perfect solution just yet.
This driver cover from a cheap headset dampens certain frequencies depending on how the holes are drilled, combine that with a thin layer of acoustic foam to stop any resonance effects against the plastic and it seems to soften the upper frequencies whilst also lowering the db level.
The sound is more dispersed by the foam, filling the cup as it would with a foam filter alone. Making it sound full.
The only negative is the funneleffect that the extra lenght the sound needs to pass around the cover is causing, I think I can fix this by buying or making a new cover witha wider diameter to extend a few mil over the edge of the driver’s diameter.
Clarity takes maybe a 5% hit but I’ll try the thinner foams I purchased on aliexpress once they arrive to see if that helps.
I know the driver already has a cover but it’s very open and reveals all the harshness of the upper frequencies on poorer mastering or brighter tracks. I didn’t notice barely any dull treble effect by this mod, it just tames harshness of and makes it slightly less grating.
The upper mids are noticeably less harsh though, female vocals sound more forgiving, especially when there’s sibilance in the recording.
