What's wrong with the shape? They're ported.
Not sure about the brown plastic myself, but that can be easily remedied. I don't actually have them yet, so no idea as to the sound except for what I've heard through the impressions I've read.
I've wanted to try Ortho's for a while, and Steve's woodwork is impeccable... and these were tweaked by Wualta, and he is as much of a crazy mad scientist as Patrick, except that he is sane.
That combined with the nice fit of the beyers and the L3000 earpads tells me that this should be a nice companion for my K340's.
