Anyone else struggling with the thump of a kick drum distorting through external speakers regardless of volume? And I swear I hear it distorting through my bluetooth headphones too... Every time a heavy kick drum comes it I hear a sound that's reminiscent of a blown speaker cone. A sort of muffled flapping. It's not the speakers or the cable. It's the phone. Tested in multiple places. Had the issue with 1.5, and now still having it with 2.1.
