MX 150/100 if you want to have a mic, DT990 Pro if you want open-back and DT770 Pro for closed-back.
Worth mentioning that they're studio headphones, so if you like headphones with a lot of bass you might have to consider other models.
At home I use Sennheiser Game One, before they were rebranded to EPOS. I really, really love them so if you can find them second-hand, go for them. They're hooked up to a Sennheiser GSX 1000. I use this setup for almost three years now and I'm really happy.
For in-ears I use Marshall Mode EQs, I'm on the third pair now and am also really happy. They've got a lot of bass but when I'm commuting I actually prefer it over "true" sound :)
As always with headphones, YMMV. I care about good sound but I'm not that much of an audiophile to care about exact frequency curves etc.
