you pretty much wrote half of the pages in this very thread so I guess it's time to consider switching boats huh

Real deal with 500 is extracting its drivers from that craptastic shell then you get to realize how uncomfy its nasty headband really is and how much SMC acts a major bottleneck, as it was designed to transport coax signals and never meant for analog audio anyhow.
Not to mention that with stock shell rolling earpads mostly boils down to polishing a turd IME.
