Gaming headphones and musical headphones are different, *ahem*
Really, they give off different kind of tones and vibes,
Gaming headphones are often described to be, durable, good isolation, good comfort.
Musical headphones are firstly described with good sound, good comfort, and good isolation.
In all honesty, I have never bought a good headphone at all, my previous purchase was a 70buck headphone by sennheiser, they are used more for travelling purposes.
I would actually recommend the m50x, firstly they are durable, secondly, good sounding, and they the kind of "heightened " neutral headphones out there, ( heightened because they aren't really)
I could recall years back, I have a friend who would always bring out his m50s and would casually walk around with it, he use it for general purposes, well, except for gaming, he uses razer because it suits the game because of its EQ, well, to be said.. there aren't really any one headphone that fits all purposes, for example sound engineers uses a neutral one, a bassist and drummer would choose one that has a V shape or U shape signature, vocalist with a focus on the vocals, and the audiophile who simply just get fork out all the money they can find to get an "audiophile grade headphone.
Nuff to be said, I always think it depends on the user, and that's of the reason why I bought a china oem rather than a standard brand in ear.
