Headphoneus Supremus
The OPs description in this thread is very similar to what I'm experiencing . The mid bass is there but lacking rumble like its rolling off.

hmm. is the clamping too tight? maybe thats throwing the sound off? have you tried maybe wearing it a little bigger than what you feel is right or smaller? Just trying to figure out whats going on here!
