I recently received my pair of Lawton Audio Denon pads.
Put simply, they fit the HE-6 perfectly, and offer amazing comfort (very similar to LCD-2 pads). The angled aspect is a big plus, as it allows for much better seal.
The price tag might be a turnoff to some, but I prefer them to the Beyerdynamic velour pads, and to any other pads I tried.
I'll try to post a picture soon; the headphones look great with leather pads.
