I continue my contribution for SRS WOW so here it is also for HD2. I do not know if it will work on other devices. Im not responsible if something happens to your device (bla bla :P ).
You might need to tweak it a bit to match your preferable profile.
Please share your settings .
Some info about SRS:
Adds 3DEffect, Boosts Sound, Bass, Treble, Presets.
Please report for any issues that might appear.
Version 2.1 change log:
+ Ideal settings for better listening experience thanks to donalgodon.
+ Internal stereo stays on after restart.
+ Added shortcut to Programs and changed icon to both Start/Programs and Settings/System locations, thanks to VeEuzUKY.
1. Install the CAB to \Device.
2. DO NOT ACCESS THE PROGRAM.
3. Soft reset your device.
4. Access it's settings from Settings -> System -> SRS WOWHD or Start -> SRS WOWHD
