So , the nowdiscontinued AKG K 530 . These were AKG ' s entry level audiophile headphone and had large varimotion diaphragms . Their specs on paper aren ' t too interesting 1826 K response with a rolled of curve towards the subbass . 55 ohm impedance with an efficiency of 102 dbmW . They have an attached 3 m cable which feels great actually and replaceable pads . The headband is genuine leather and the whole thing is a solid chunk of plastic . It doesn ' t feel quite as premium as one would hope for its original MSRP of around $ 200 but it makes up for it in sound . It ' s very neutral . Very inoffensive . Natural . There ' s an ever so slight increase towards the midbass but apart from that , the treble and midrange all blend together nicely . The soundstage is very average . Nothing big but nothing too small . They ' re very ' unimpressive ', if one could say that , but not in a bad way . Think of it like a Mini Cooper . It ' s not going to blow anyone ' s mind , but it ' s effective , drives well and makes you appreciate the ride . The comfort isn ' t too bad either . The pads on mine are very worn , but finding replacements is really tricky .
