Was really looking forward to FOB.. What is the status of it? You still developing it or did you drop it and just make a 2d version? That game looked really good.
I personally use the Kingston HyperX Cloud Core headset. Great sound with good highs and lows (neodymium speaker magnets) and a good quality mic. Can pick them up for about $80CDN shipping included.
If you have money, ODell's idea is generally best. I would go with Senheisser headphones with angled drivers and a good quality third party mic that attaches to the headphones.
