Seriously.
Yea I've read around 4kHz is the frequency which is easiest for us humans to perceive, why naturally many headphones have slight boost in the bass and slight boost in the highs to make up for it.
If you don't like mids, you don't like music. Simple as that. Music lives in the mids, not bass, not highs.
If you boost mids and you hear a scratchy sound, that means you are either using the EQ wrong, using a terrible EQ, using inadequate headphones, and/or you don't know where the midrange frequencies are.
Dynamic headphones have trouble reproducing a full and balanced midrange without getting congested. Most likely you are hearing congestion.

Its like saying you dont like food.
i was a little off, i assumed that 500hz was still higher bass, and that after 4khz its highs. correct me if im wrong but isn't the most important part of human hearing from 500hz to 4khz, as highs are a lot harder to hear, and mids are generally vocals/talking. just something i thought, wouldn't mid range be the most sensitive part of your hearing.
Time to go into a high end audio store and demo some of their stuff with your usual music! No more trivial threads like this one and the rest you have posted...
Also should not have bought Shures...
