Jerg, you will eventually get some dirt in there.  Or let me put it this way, if a lot of people started doing that mod, some of them would wind up with ruined HE500's or HE500's in need of repair.  I have ruined orthos before from leaving bare drivers exposed while I have the cups opened up working on damping schemes.  Some drivers can be taken apart some can't unless your name is Don.  ;)

pantyhose shouldn't do much, I'd recommend that but do what you want.

What you can do is put the protective fabric directly at the back of the driver instead of on the grill, that would minimize the reflections.

That's a good idea.  I don't think panyhose on the grill will do anything though, if anything it will do a bit to help reflections off that wire grill.

Hm, I might cannibalize a spare set of HFM pleather pads and use the fabric screens on those as a backing then; they seem to be extremely transparent, possibly more-so than other fabric options.

Although the "fabric on grill" vs "fabric on driver" is still in the air...oh which to do, which to do.

It really doens't matter if you use something like pantyhose.  I have the Hifimans here and that's the same kind of material on them.

Done; crude job but it's a functional mod. Ended up ripping off the fabric from the stock grills and taped them to stretch flat over the back sides of the drivers (it seemed to be a finer and less densely-woven fabric than pantyhose cloth).

been trying these quite a bit with a friends FiiO E17 now, super impressed. used the pleather pads which weren't the comfiest though. but they seem more comfortable than what I remember my HE-4 being. sound is among the nicest I have heard even with such a weak amplifier/DAC. think I will try them with the Burson HA160DS or if possible the Gungnir/Mjolnir combo next, as they have that in the store for demo. amazed how well the treble behaves.

The Burson HA160 is an amp that makes everything sound like smooth boring mush.  If you audition the headphones with the Burson you need to understand what is the sound of the amp and what is the sound of the headphones.  I don't consider the Burson a good amp to audition headphones with because it adds to much of its own sound and color and character.
