Summary: I found these brand new at a local thrift store brand new for $30! To me due to them being very colored to my ears, they're not worth that. Their sound signature just doesn't play well with my ears.
They do feel like the bass is a bit excessive. I think it seems worse than it is due to a severe lack of treble. These aren't as dark as the TMA-1, but maybe close. Some of my favorite tracks seem to sound a bit murky and almost congested.
Pros: comfortable, cheap
Cons: too dark, very shouty mids, slightly bloated (sounding) bass
