Had a quick A v B test last night and this morning, alongside the K702 and still prefer the AKGs for gaming. Mind you I play a lot of FPS games so the wider soundstage of the AKGs probably suit that genre more?
Testing them both particularly on Destiny 2, the HD58x sound good and offer a little more warmth and thump with the weapons but although weapons perhaps sound a little thin with the AKG I can't ignore the fact they make me feel like I'm in a huge, expansive world. The atmosphere they help to generate is just far better suited to the games I play. They do need a fair bit more power though compared to the HD58x. Other advantage for the AKGs for me is being able to use the VModa Boompro with them so they are far more convenient to turn into a headset also
