Well it doesn't damage Stax anyway, I wouldn't think it would here either. Still, it's a very annoying thing to have to just deal with. It's fixable through driver design, but that obviously doesn't help here.

This is the sound of air pressure moving the dust cover and diaphragm. Those leather pads create a better seal than whatever you were using before, and the air pressure inside the cups is shifting the films around. On Stax it's know as "Stax fart".

The ESP95X is sensitive to dust, Stax are not. Draping any sort of plastic covering over the headphones when not in use should be plenty, but often the ESP95X/ESP950 come with dust in the driver from the factory and it'll eventually shift into a position where it causes squealing. In that case, giving them a hard tap can dislodge the dust, and hopefully it'll settle in a place where it isn't causing noise.

That being said, electrostatic headphones are most sensitive to dust when in use, the fields created attract it, so *shrug*, Koss should really be more careful when assembling them, and fully seal their drivers.

If you want to use an air purifier to get rid of dust, you're going to be looking at something large and intended for medical or scientific purposes I think, no HEPA filter I've ever tried has done anything noticeable to the amount of dust in this house.

In my 10+ years of experience with headphone communities, neutral definitely is not what most people enjoy, give them a headphone that perceptually has all frequencies at roughly the same volume, and itll get called boring by the majority. Whenever I see someone call a headphone neutral, it's almost always a little v shaped at the very least.

Not neutral is definitely easier to engineer though. Headphones in particular, by nature, don't start out flat, and often fight you every step of the way if you do try to coerce them into being flat. A fix one thing, 3 more go wrong kind of thing, every change you make has cascading effects. Speakers are far easier to work with if neutral is your only goal.
