You say a pair of 2.5mm earbuds came with the phone? Where'd you buy your phone at? They put the wrong headphones back in the box. The 6682 uses Nokia's proprietary Pop-Port for audio. You need a headset with the Pop-Port adapter, i forget the model numbers. Or something like the AD-41(5?) that adapts the pop-port to a 3.5mm headset. Either way, you need new earbuds.
