It's to the point now that I have to stay completely still when using these things or it sounds like I have a pair of crickets on my head. It's very frustrating. Anyone posting frequency response graphs for the headphones needs to include the huge hump at 7khz caused by the constant creaking!
You might try some lithium grease. It's safe for plastics and might silence things a bit. They sometimes use it on M4's, so maybe you can find some in Afghanistan. Try it out on some test plastic first, though, to make certain it's pure.
PTFE (teflon) lube is an even better choice and I've read of people using that on weaponry, too. There are approved lubricants for military issue. If you can find some and it turns out to be lithium or PTFE, that would do the trick.
Just be careful, though, because a petroleum-based lubricant will dissolve the plastic, eventually.
