My previous phone (HTC Desire 610) with BoomSound would blow my ears up. I just bought an internationally unlocked HTC Desire 830 assuming it would at least play as loud, having BoomSound as well, with my Sony buds as the 610 did. IT'S BARELY HALF AS LOUD AS THE 610. I've adjusted everything on the phone and have even gotten it to DEV MODE and nothing has helped. All those sorry "Volume Booster" apps don't help either. I've even gone so far as to nearly root my device but at that point I am a novice and did not quite make it to the root. The phone has Marshmallow OS. I am very disappointed in the sound, otherwise I'm enjoying most of the phone. Any suggestions?
