ok since no one has resolved this issue, i would like to let everyone know that i have some progress.

1. Download this acoustic set (W760 Acoustic by Richard.rar) and flash it to /ifs/settings/acoutic

2. Download these acoustics and flash them over your newly flashed acoustics from part 1 (again in ifs/settings/acoustic).

3. I found that to get the best sound from the heatset, you have to use the manual equalizer preset, and crank the bar furthest to the left to its highest possible point. That will increase the base (of course) and then set whatever else you want.

Its much better this way, but still nothing compared to Pete's Acoustics for db2020 phones, whose megabass in unmatchable. I will keep everyone posted on any futhur developments.
