I think you'e going to be quite happy with these, they're really not bad at all.
I had a moment when I thought they sounded awful, but then realised I had Dolby atmos and the accessories app both try to apply their EQ settings, playing tug of war.
I put Atmos to performance mode and let the system EQ do its thing. Can't quite decide if Atmos is actually better than Sonic yet, but thus far I think Sonic is better in COD cold war, and Atmos better in Prey (the only games I've played today)
I was swapping and between my headsets today, and given that the Sony XM3 are widely regarded as some of the best noise cancelling headphoens you can buy, for gaming, these really doesn't lag behind so badly. They're not as subtle / detailed as my XM3 are, but they're much better than the price would suggest and they're certainly not immersion breaking.
As everyone said so far, the bass is super heavy and needs to toned down a lot.
My EQ so far is just at bass boost off; 125HZ (-5), 250HZ (-1), 1kHz (-1), 4kHz(0), 8kHz(0).
My biggest gripe so far .... is the "new" plastic smell. With some new cars it makes me ill, and I've never experienced anything outside of brand new cars, until today. The new plastic smell makes me feel queasy and needs to go asap!
