Unless your cable is too short to have enough slack to rest on the ground between you and a TV, I can't really see any practical gain for what makes wireless more convenient. It's more of an aesthetic thing for most people... and how much acoustic sacrifices someone is willing to make for aesthetic pleasure vary greatly, person to person.
I'm not judging aesthetics as unimportant though... I recently delayed my car purchase for a week so I could get a blue one, and even more recently I waited like 3 weeks to get a silver iPhone (looks great in my cognac leather case)! I wish my K712 had another orange ring, a large one around the edge of the earcup grills.
