I found the controls a bit confusing at first. Cut the mid, and the volume drops significantly I find, and some find them a bit mid-shy, but cutting the bass & treble and cranking the volume (which it certainly isn't lacking) works for me. And once I got the hang of it, it's dead simple.
Talking of volume, get it past about 6 (1-2 o'clock) and it's like the afterburner's been switched on
Love mine...
