"good for gaming" is quite relative, if you want to be able to for example distinguish footsteps in cs:go more clearly, you can fix that in softweare if you so choose when you play, for anything else you really want to get some headphones that go really close to what the original composer/sound designer intended to be heard in the game, so you want a "flat" frequency response (if you want to understand better google frequency response of beats headphones (they have too much bass and non existant mids and shitty highs, and then google something like DT990 or HD650 frequency response and you'll see some flat shit that sound tight)
The main choiche you have to make is between closedback or open headphones, you can google to get the detail but (and I am oversimplifying) Closed headphones isolate you better from outside noise EG your fans but do not give you a realistic representation of where sound seems to come from (this is called the sound stage), on the other hand open designs let sound both in and out but they give you a much better sense of space.
Generally low end headphones tend to be closed.
Here is a list of headphones I tried in real life that sound really great (for other headphones not included check reviews):
Audio technica ATH-M50/ M40/ and M70 sound nice (the M70s are my current daily driver)
Sennheiser: HD 558/598, if you want really dank ones get the HD650s (they sound amazing but you will need an amp)
Beyerdynamic: DT880 and DT990 and pretty much industry standard.
I once tried Audeze LCD-3s at Superbooth in Berlin and I must admit that my underwear will never be the same from that day on...
