Thanks guys !!!
@x3060: Your phone supports A2DP... instead of the 3.5mm adapter, I would suggest you to get a A2Dp compatible headset. The A2Dp audio quality simply is brilliant, must better than thru adapters.... I have an AT&T tilt (HTC TyTn 2) and earlier I used to listen using the miniUSB-to-3.5 mm adapter found here:

I used to listen using my Sennheiser earbuds, the sound quality was OK, but far inferior to what I get when I connect the same earbuds to my PSP.
Then I switched to A2DP headset HT820 from Motorola, its cheap and both music/call quality is superb. Only downside is that after more than 3-4 hrs of listening, it gets uncomfortable wearing the headset on the ears.... if you can get hold of a pair of thiose and its brilliant !!! A2DP FTW !!!
