I'm on the same initial situation. I'm looking forward to buy a k702 OR a AD 700x. 90 % of my use case is gaming at a competitive level. Because of the big soundstage I tended first to the k702 but i read a lot about the lack of good imaging (no good directional sound). A good gaming headphone should have a really clear imaging for categorize the footsteps well. Because of this negative feedback I'm somehow surprised, that the k702 has this excellent (10/10) competitive rating at the guide. Because of the imaging i tend now to buy the AD 700x. Has someone experience on both cans (related at competitive/fps gaming)? and has the AD 700x decent build quality and run well on onboard mobo (ASUS ROG Strix Z370-F Gaming)?
