It's best if you're concerned about money to get headphones and mic separate. You can still get somewhat decent quality this way without having a crazy high price.
Just do something like
Headphones : http://www.amazon.com/Superlux-HD661...dp/B0062OOFAY/
Microphone : http://www.amazon.com/GE-98950-Micro...dp/B000BYCNKU/
Around $50 and the quality will be passable.
Though the best part is you won't look like one of those dummies with a dumb "gaming" headset.
