Dekoni’s product page explicitly lists HD6XX among compatible Sennheiser models and offers the listed variants: sheepskin, fenestrated sheepskin, hybrid, Elite Velour, Choice Leather, Choice Suede, and Velour. The page also describes the pads as deeper than stock and claims this enhances soundstage; that is Dekoni’s product claim, not independent acoustic verification.
