Someone should try and put the ksc-75 headphones in the enclosure. I think they look pretty sleek, and very portable too. This is a pretty genius idea but I wonder how much the SQ will suffer, or enhance?

This is exactly how the "Extreme Isolation" headphones are made.

Koss 60ohm drivers are a poor choice for this job, btw, since they're designed for open-backed enclosures. They will sound much worse crammed inside hearing protectors.

ah, so can we just assume its never gonna sound good with any driver?

Well . . . . I think it's guaranteed to never sound *great, but if you took a driver from a headphone designed to be fully sealed and fully damped, it would be hard pressed to sound worse this way.

You could just wear IEMs and hearing protectors over them.

I made some headphones for my father out of some KSC75s, a bit of copper mesh, and some cotton batting. However, the bass sounded lousy until I bored a bunch of holes on the back.

While they're not exactly very good for noise isolation, they sound pretty decent.

This trick has been around for quite a while. About 20+ years ago I slipped some headphone drivers into an old pair of David Clark earmuffs. Now these were NOT slim and foldable but they did very well for what I needed. Between the very loose driver fit and the large volume I am sure they didn't suffer from the typical closed headphone signature. Anyway, it was better than the whine of power tools or the garden tractor with a 5 foot mower deck.

Nice! Noise isolation headphones on the cheap (really cheap)...
But as said, I would pick some drivers from a closed back headphones. Since they are optimized to play in such an environment.
