I wasn't sure if I should post this in equiptment or technique, but I figured technique was about right.
I bought some Vic Firth Isolation Headphones upon the recomendation of everyone here on the boards. They work great and I'm happy with them. My ears thank you as well.

The problem is that my snare has kind of an annoying sound to it when I'm using them. Evrything else on the kit sounds fine (although dampened) but I can hear the cymbals, BD, and toms over the music without the tone changing much.
The snare however, is transformed into a kind of an irritating, hollow, dull thud. No snares, no snap. It's almost like my ears can feel the snare, rather than hear it.
So I decided to try and mic the set and feed it through the headphones to try and get a clearer sound. Now I'm no sound enginer, mind you, so i'm experimenting a little bit with 4 area mics, but it seems the only sound I can get from my snare, sounds loose, hollow, way too open.
I've heard there are some "tricks of the trade" for micing a snare drum but I don't know any of them. I'm open to experimentation and toying around until I get a decent sound, but I'm not sure where to start really.
Overall I like the way my snare sounds without the headphones. I don't really want to retune it because I know that naturally it sounds fine. But how do I solve this problem with the iso phones? Or is this something I'm just going to have to learn to live with?
