want to reverse the sound

Hi, since I'm little I'm playing with my headsets backwards because I didn't liked having the mic on the left (yeah..stupid idea) so I'm kind of used to the reversed sound and I can play accurately, spotting ennemies and monsters. But my carcharias sur broke and I bought a Vengeance 2100 and I thought there'd some "reverse sound" checking box in the software, my MB audio software is just for jack so...I've been playing like this for like 10+ years and I would like not to have to adjust myself, something that could take a while. If someone could help me. Thank you
