I tried out cheaper ones from Superlux just for fun and never felt the need to move on.
My favorite has been Superlux HD330 open backs, which are copies of DT880. Hard to drive, but great sound that outperforms many headphones in the $150-200(as per audiophile forums). Not the most accurate in footsteps(not bad but not super amazing) though. They broke on me after 4 years and I just re-ordered the same ones again.
Heard that Samson SR850(Superlux 668b) are another ones often mentioned as value option.
JVC HA-RX900 - very comfortable semi-open with very precise audio and footsteps, but not as good instrument separation and soundstage as HD330.
