This may be slightly off on a tangent, but I know several have discussed how to mod their headphones by adding a mic for their gaming needs.
I'm in that position right now, but my main concern is what mic to use in order to get decent quality sound (just for chat, so no biggie) as well as some fair-to-good noice cancellation. Any tips in terms of a reasonable mic with some noice cancellation (reduction, more likely...) would be great. I haven't nailed down which headphones I'll go with yet, but I can sort that out through testing myself as I need to hear how things work with the DAC/headphone amp that I already have anyways. The mic is much more challenging to even find contenders to!
