I see. I thought he meant it being closed gives the driver more movement, from the way it was worded.

Listening more, I found that the mod was far too fatiguing. The treble was just too much for an extended period of time. So, I made ~1.5 cm holes in the middle of the cardboard rings, making donuts. The bass lost some of its attack but gained a lot of heft, and the treble was lessened. Then I pulled the cardboard out, and the headphones sounded the same.

Lesson? The main reasons for the "improvements" were half placebo (difference=improvement), half high listening levels. When I turned the Beyers up to the level I'd been listening when I'd first done the mod, I could hear all the bass impact and detail I wanted. In the end, this mod didn't really work for me. I can see where it would improve things, though. Maybe using a foam instead...

Oh, and I also saw another horrible effect of this site: I'm now not afraid of pulling apart high-end equipment and sticking cheap materials in it .

Same for me.It was treble attack !!!!Can't stand that ! But its always interresting to be able to mod headphones to obtain different sound signature.For some it may be for the best but this one wasn't for me.
Had fun trying it though !
