I want to go with the AD700x, but here where I live they cost twice as much as they do in US. (roughly 205.31USD acourding to google.)
I use the Superlux HD 668B from the "build your own headset" video. I think they sound good, (especially for the price) The build quallity seams not to be the best, but suprisingly they survivred quiet fiew drops. The cables aren't the best but then again, I go through headphone cables very quick untill I found the Vention braided headphone cable.
Anyway IDK how good 668B are compare to something like g930's. Im probably no help with a review of my cheap (but still good) headphones. You are probably looking for something better. (like the AD500X)
