I recently got this headset, and wow is it good. My only issue is when certain people talk on discord, I can hear a really high pitched ringing. I fiddled with a bunch of settings, computer audio and discord, and nothing seems to solve the issue. It is primarily if not all in my right ear only. Is there something wrong with my headset, or was that ringing always there I can just hear it cause the headset is THAT good? I haven't had any issues with any other application, though I have yet to test if I can hear the ringing on a different version of discord, say on my xbox instead of my pc. Only other issue I've had is occasional static, but I can't tell if it's from the headset or the show/game/etc.

Besides AKG K712 I have Sennheiser HD6XX, and AudioTechnica ATH-M50, and also some Chinese earbuds (around 5 nos.) which I bought inspired by https://www.head-fi.org forums. From all of them AKG K712 is the best in resolution, air, and crispness. I like them very much, but I cannot listen to them for a long time: 1 hour is maximum, after I feel discomfort. People say that this is normal with high detail headphones.
In comparison HD6XX is slightly warmer, feels like more punching but probably less detailed bass; mids are slightly more defined, and heights looks like more rounded (all is very subjective). Yes, they are different. In general, if switching for the comparison between AKG K712 and HD6XX, AKG may win in short term because of its resolution and air. But for a long run HD6XX is a champion – they provide a very pleasant listening without any fatigue. So if you want to impress your guests with the sound – then maybe better to choose AKG K712, but if you want to listen to the music for a whole evening- then HD6XX. AKG is more analytical and Sennheiser is more musical, but the difference is not that big as it may seem from such “definition”.
Now, regarding O2 Amp. I feel that it has no effect on sound signature – it is just completely neutral for me. O2 just gives enough power to drive my headphones from a laptop and that all. And believe this is more than enough.
Also this helped me a lot in making my choices: https://www.head-fi.org/threads/headphones-for-metal-music-ultimate-solution.715478/ And you can see there that K712 was appreciated more that HD650. And finally leap said: "Overall, in my opinion, 712 today are the best cans for heavy genres on the middle level "
