Now, to be fair, Grado SR-80s aren't exactly a reference, neither in sound (colored and overly bright with limited bass) nor wearing comfort. Grados have always been considered an acquired taste, they just were ubiquitous and cheap in the US (and SR-60s were actually half-decent for the price). Maybe snag a pair of Sennheiser HD58X or HD560S one of these days, those are some decent cans.
I'm quite happy with my HD600 (2019)s these days. They basically sound like a pair of decent speakers with a bit more up top. I give 'em a bit of Meier crossfeed courtesy of the Foobar2000 plugin. No, I would no longer go for headphones as my primary means of listening these days (not since I upgraded my PC speakers to K+H O110s, got a measurement mic and REW and EQ'd the whole shebang), but for in-bed listening these cans are mighty fine.
