Honestly, I was a bit underwhelmed by the Q701 for competitive gaming purposes. While the sound was very diffuse, I didn't find the cues themselves to be exceedingly precise or accurate. While it'd give me a good idea of what quadrant noises would be coming from, I wasn't always sure of their precise location. I'd even go as far as to call it misdirection.
I think the W3000ANVs are better in this regard, and perhaps even the W1000Xs. The W1000X felt more accurate to me than the Q701s, and had a benefit of subjectively better immersion thanks to its frequency response.
