Discuss about what headphones you believe are for the most part a more expensive version of a cheaper headphone. (Basically a upgrade to the cheaper headphone.)
Example that I know of is Focal Elex to Focal Clear. Is one of the higher end Focals also a upgrade to the clears?
dt 880 -> DT 1990 analytical pads similar in signature much more refined more body potentially more detail
DT 990 -> T1.2 relaxed and refined
DT 770 ->1770 refined bassy and bright -> T5P more balanced V but still real bright and bassy =/= 177x GO heavily balanced small V
Fidelio X2HR -> Tygr300r better imaging not as muddy bass
AD700x -> AD2000x better across the board
K612 -> K702 refined, deeper pads, detachable cable
