Im sure its been done to death but Looking for a multipurpose set of cans for music and gaming with a wide variety of genres.
Something with ease of use and hence low powered for plug and play with a variety of peripherals (phone, laptop, desktop and ps4)
above $100:
•ATH-AD900x
•Philips X2
•DT990
•Sennheiser HD598 or 599
You have two very different type cans in that list:
AD900x and HD598/9 are very neutral bass type headphones.
Which is needed for the highest level of "competitiveness" in hearing foot steps and such.
But that also cripples "fun factor"/immersion rather badly with grenades etc not sounding of much anything.
(before DT990 had HD595... with bad experience from durability of that fashion design)
DT990 and Fidelio again have clearly above neutral bass, but without it starting to drown everything else...
Unlike in cheap (especially closed) gaming junks.
That drops competitiveness one notch down, but gives vastly better overall balance with good "fun factor"/immersion.
As for mobile use with low impedance Fidelio would be easier for low operating voltage devices, assuming noise floor of source is low.
(high sensitivity, low impedance cans are very sensitive to noise/interference)
Standard integrated Realtek chips of PCs easily drive 250 ohm DT990 far to hearing dangerous volumes.
But some weaker smart(/toy)phone output might have problems with higher dynamic range content. (32 ohm DT990 would behave similar to Fidelio)
Also for some music you might want to tone down 8kHz band in equalizer for DT990.
In games/movies that treble isn't much of problem.
