I wish I could so I could buy the comfiest headphones out there.

Even with oratory's EQ presets as in all profiles from the same source all my headphones sound quite noticeably different. HD598, DT1990, Hifiman Arya SE and the samsung galaxy buds+ after EQ.

They're closer to each other with EQ but every time I swap to the Beyer DT1990 from the Arya and vice versa I notice that the DT1990 has more micro details in bass instead of being this big slam. In addition the DT1990's electric guitars sound a bit muffled in comparison and with some specific music the soundstage just isn't there. The HD598 really lacks in micro details in bass. The Arya not nearly as much.

These aren't huge differences but noticeable enough for me to swap between both every once in a while to spice things up.
