Almost forgot about the hifiman deva, it's been a while since I went looking for wireless open-backs. The cups on those should be much more comfortable than the grados.
It really depends on the headphones, my sundaras sound like I'm wearing miniature speakers on my head. I let my friend try them out and he had them turned up really loud, I could hear his music through the door and down the hallway lol.
Get a pair of decent planars that take eq well, they do something special with the bass compared to a normal dynamic driver that I just fell in love with. My personal preferred pairs are modhouse argons and hifiman sundara and they both sound beastly when you crank the bass up but still retain very clear sound.
Both will require an amp though, which I realize will put a lot of people off, but it's so worth it if you're really into music. It was like discovering all my albums over again.
The ksc75 sounds better IMHO, especially when they're used with a headband, and they're cheaper to boot. I used them to fix my pair of porta pros when I messed up the cable.
Treat yourself and get the yaxi pads for them too, it's so worth it.
That first album snagged me hard. I think I still owe Columbia house $16 for it lmao
