Audio on Bluetooth headphones sounds like a 2002 cam movie

Bought the MCC because I wanted a cinamatic shooter with amazing audio to enjoy with my great new Bluetooth headphones. Unfortunately the audio dropped quality tremendously as soon as I loaded up the Halo three campaign. It's so bad it sounds like I'm playing a bootleg copy I could have picked up for 20c in Indonesia.
Any one have any solutions before I request a refund?

Correction. It sounds like a heavily used rental vhs from 1997. With headphones the sound is garbage and without most of the sound doesn't work at all.

What headset?

Wire your headphone or change the mic receiver and transmitter to something else I had the same problem.
