Direct Sound EX29 vs Sony MDR 7506/Sennheiser HD280

[fcvapor05]

Hey yall.

I'm in the market for a pair of headphones for recording drums.  I'm very familiar with the 'industry standard' Sony and Sennheiser offerings, but while I was fooling around online I read a few reviews of these Direct Sound EX29s.  They look to me to be the best pair on the market from the isolation standpoint, and appear to have very flat response, so good for listening to the mix while playing over it.

So, anyone using them?  Any info on these compared to the Sony/Sennheiser?
