People complain about the fit, and the lack of clamp force and sadly I did not experience any of this, I put them to 4 on each side slapped em on, pressed them in ever so slightly and enjoyed. I will mention that they sound DRASTICALLY changes depending on how far from the front of the pads the front of your ears are. Essentially for me, the closer the back of my ears are to the back of the pad the Thicker the lower mids are, the closer the front of my ears are to the front of the pads, the thinner the entire can sounds!
Sounds like based on your experience, one really needs to try it in various front to back positions to see what works best. For me it's forward more. I bet it has to do both with the size of the cups/drivers, whatever imaging/soundstaging setup AKG has in their, and the fact that everyone's head and ear shape is different.
Now how do we get all the people that gave them mediocre or bad testimonials to back and try them
