I got velour/stock pads. Haven't tried Dekoni on the HD6XX. I don't believe sound quality can be improved/changed significantly by swapping pads (thicker or thinner) so not really into experimenting swapping pads. I only had a chance to compare the HD6xx to the HD800 I own. Different beasts, the HD650 got more bass emphasis but lack in mid range clarity and sound a little muffled due to this. For the price, I grabbed a second pair in this drop too.
