What "sounds" good has little to do with any accuracy of signal's reproduction.
Human hearing is really bad as any kind absolute measuring instrument and what little is heard consciously is further mutilated by expectations and various psychological (or should we say psychopathic) biases.
For example only sound tubes have is distortion of signal and you may have noticed how many people call their sound as good.
In some blind tests tube worshippers have been induced to hear tube sound even when listening sound through normal low distortion semiconductors just by hinting about tubes...
Also you may have noticed how HD600-serie Sennheisers and especially HD650 are called good with their "warm" sound.
While that warm sound actually means inaccurate frequency response with emphasis on lower end of frequency spectrum and reproduction starting to get weaker at upper mids and dropping further the more you go into treble.
Something you down't want if you want to pick gaming environment apart from sounds.
Stereo content like music simply doesn't care much any about accuracy of reproduction.
Only thing our hearing is good at analyzing reliably is binaural cues, which are used by brain to "decode"/process sound source locations.
You'll hear it very fast when those aren't reproduced accurately enough.
I had once chance to test one Turtle (more like turd) Beach gaming headset.
Obviously expectations were really low, but starting listening from music actually gave better than expected result with kinda "front row" agressive feel in say rock.
Switching to binaural sound gaming clips was like running to wall.
With immersion best described as "head in bucket under water" with no real sense of distance and especially separation.
Everything sounded like coming from next to ear, with some sounds just being more muffled than others and of course directionality wasn't good.
In comparison Superlux HD330 bought for 30€ sounded like top level headphone with binaural sound.
I didn't even consider wasting time in testing against audio maker headphones I had that time...
Darn it's annoying surf web even with UPS for PC because of short power cuts from continuing maintenance work from yesterday's snow storm keep cutting connection.
(had 13 hour blackout from ~19PM yesterday)
Well, at least there's been only couple cuts in last 15 minutes...
