I must unfortunately connect my Vorrezensenten: While the earphones are called EP 630, but this is obviously a different type: The plug, the cables, the padding and the capsule are modified. But above all is the sound there. What used to be rich bass and powerful sound were - and we had / have nevertheless already five pairs of EP 630 - is now miserably thin, flat sound, no bass, no matching cushion (1 small pair, two pairs to large). I sent both sets ordered back. Good advice is now likely expensive ...
Supplement: 27.03.12 After returning the two (black) Sets the seller (in this case, not Amazon itself) I have again a set (white and slightly more expensive) EP ordered 630 - and what a pleasure: That was again EP 630 as we appreciate for years !
