Sideways I think you mean hot glue and duct tape??
But seriously though, the AD700 a lot of people either glue or velcro a mic to the side, and our very own sideways makes a "gaming cable" for the AKG headphones with (stock) detachable cable, which offers a mic port for a detachable mic. Those two headphones are probably the most popular to be modded for gaming around here. The rest of the ones people use, they either use a throat mic / similar, or no mic. But really, most headphones with detachable cable, sideways (or someone else) could probably come up with a reasonable (professional) solution, like the one for the K702, otherwise, you could velcro the mic to the headphones. A final option which may be more pricey and not always an option on all headphone designs, is to have someone like sideways (or do it yourself) open the headphone up, and install a 3.5mm female jack to insert a removable mic into. He's done this on some headphones in the past, and they came out good, but I'm not sure what the pricing would be since it's pretty labor intensive and there's some risk in breaking something as well. You'd have to talk to him about that, to see if it's worth it.
