I've been having a dust squeal in my right channel for weeks. I've brushed off the diaphragm dozens of times, checked and cleaned the stators for surface dust, and just don't know what's up. Has anyone had any difficult-to-eliminate squeals and found any tricks? It's usually only present in high humidity (almost continuous squealing if I try to wear them after showering and having wet hair, otherwise the squeal is somewhat rare occurring only a few times a day)
There is a fair bit of dust on the diaphragm because I don't have a cleanroom so it's effectively impossible to get fully clean, but it's no different form the left channel which rarely if ever squeals.
