With a small correction is excellent!

If you take down some 5-10K and boost bass its a perfect headphone. Deep sound 3D. Not like some other where are only treble....

I put an EQ and lower the gain so it doesn't clips when doing correction.

Maybe you need a loud amplifier of headphones if your audio interface hasn't got enough power. But mine has (SPL Crimson 2)

Glad I bought these. Very happy at last I found a nice headphone. had ATH M50X (very treble sound) If you like deep sound get these. I recommend Sonarworks Reference headphone edition to correct them.
