I'd like to know too. On Android, there are a couple of audio players that have balance control, but no system wide control that I know of. The iphone / ipod touch does have it system wide hidden under accessability (after many years of not). Anyway I have an a bad ear with limited hearing, not lousy headphones, and it does suck that such a basic feature that used to be common on older stereos (and even some headphones) is gone for whatever reason. For me with bluetooth earbuds, It's frustrating enough to back to the iphone. I'm kind of sick of having even a few simple features not added to my 822 since I got it, even though Nokia really keeps up their end of updating software, MS is MIA.
