So I recently just got a pair of ATH-M50wh's from soundprofessionals while they were on sale for $120ish and quite baffled with the sound quality. I've upgraded from a pair of Sennheiser 202 and can't really hear a difference when comparing them to the M50's. The only thing that is really standing out to me is that the bass on the M50's is stronger and tighter, everything else sounds very similar to my 202's, $25 headphones. I have had them playing music for about 10+ hours and not really hearing any benefit from the short burn-in period. I'm running the headphones through on-board audio on my gene-z motherboard and using foobar with the WASAPI plugin.
Am I doing something wrong, or am I wrong for expecting a night and day difference for the huge price gap between the two headphones? I can say from experience that I noticed an immediate difference when I upgraded from this garbage to the 202's, but is it fair of me to be comparing the m50's this early on considering the 202's have probably over 300+ hours of play time?
