AKG K702, with "reversible bass mod" as described elsewhere on Head-Fi. The modification increases bass output, thus this headphone's only relative weakness is corrected. These are several years old, lovingly and carefully used. In perfect working condition. Minor cosmetic blemishes. Am selling these reluctantly as I trim down some gear.
Edit: adding photos of earpieces, trying to show the blemishes on the outer grill. Almost invisible still, so they're very minor.
UPDATE: Sold 6/6/14.
