My Otterbox showed up yesterday. It's great for the AKG 481. A little tight squeezing it shut (that won't hurt mics, will it?) but it's solid and small.
I got mine yesterday too.
It's very solid, and more importantly to me, small.
I too noticed that it's a bit tight, perhaps pushing the mics together when closed. I think I'll just put a small cloth between/around them so any rubbing that happens doesn't result in scratches.
