Yeah, I've tried that before, and the earplugs didn't fit inside any of the headphones I tried at the time, all of which were circumaural. Also it's kind of hard to get a decent amount of volume that way. At least, trying it on the headphone amps of various pieces of studio gear, I had to turn the volume to max and it still wasn't quite good enough. At that point I was more worried about damaging the headphones. Obviously the fit issue completely depends on the earplugs and the depth of the cups, so it's kind of a moot point, but still it seems like an inelegant solution. At that point why not just get some IEMs?
