QazimokaI'm coming from the Sennheiser Amperiors (better version of HD 25s) for DJing electronic music and use the 553s for studio music production, mastering, and gaming. Amperiors have a better midrange and a fun bass and with an amazing seal; 553s have vastly better soundstage, separation, and neutral bass (it does register sub bass, just not at high levels). I'm extremely happy with both for my specific needs. The former for consumption, the latter for creation.
