Here are my two cents since I have a pair of SHP9500 and DT 880 Edition 250ohm.
I gotta say the DT 880 is hands down way more resolving than the SHPs. I blind tested a couple of friends with those two and they got right 9 times out of 10.
I keep coming back to the SHPs because of the convenience of the vmoda mic. A much much cleaner and simpler solution than a modmic in my opinion. A dedicated Mic is another piece of hardware and cables. modmic is an additional cable as well. Just not for me. That is sort of personal, I am a minimalist in that sense (even my pc case is an Ncase M1)
Regarding the above, I can guarantee you that motherboard will drive a DT 880 Edition 250 ohm with no problems whatsoever (my DTs connected to the front port of my gaming rig on the picture below). In fact, it’s the low impedance SHP9500 that would suffer more in terms of sound signature. Why? I made a whole post about it.
Now in terms of pure sound quality for competitive gaming
I couldn’t agree more here with @Falenkor, Beyers are the best choice in this particular case. I do enjoy the convenience of the SHP9500 + vmoda quite a lot. It’s really up to you what you value more.
PS: I got the DT 880 Edition 250ohm for 138 quid, the price varies quite a lot.
