Each audio output in Windows can have unique 'enhancements' applied to just that output.
Right click on the speaker icon in the tray and choose Playback Devices.
Highlight the headphones (or whatever your earbuds device is called) and click properties. From the tabs at the top, select Enhancements.
Check Disable all Enhancements, then apply.
Some soundcards will have different options avaiable, like room emulation or a graphic EQ.
Disable everything and check the earbuds for reverb. Once you get it sorted, add back EQ or whatever you find useful.
SInce you have some proprietary HiDef stuff, you may have to fool around with trying to disable these completely.
It took me quite a while to get a straight sound out of my Toshiba LT when I was trying to use it with Sonar.
It has DTS sound. I finally had to uninstall that and also revert to the WIndows HiDef driver.
