aguillon5, not to start a fight, but first off, it's not white noise. Second off, I don't believe you. Third, I'm an electrical engineer, with experience designing USB devices and voltage converters, so I actually do know what I'm talking about (exterior to the phone, at least).
I haven't ripped my chargers apart (too lazy so far) but I'm guessing they're using cheap switching dc-dc converters, which can and generally do generate noise. It's not white noise though, that'd be full spectrum. Switching converters will generate noise over a pretty specific frequency, though with harmonics and other phenomenon, it's possible for this to be pretty wide. What I'm curious about is if anyone is specifically selling a "no-noise car charger" designed specifically to allow Android (or other) smartphones to charge in the car while still maintaining a high quality audio output.
If no one sells one, maybe I'll just build one myself. I doubt it's too hard, unless Samsung is doing something crazy in the phone that's generating the noise. If that's the case, then yes, you're right, and we're all well hosed. I don't think Samsung is that dumb though, if you're designing a high end piece of equipment it's fairly trivial to ensure there's no noise bleed through. Of course, when you add in fly-by-night car chargers, all bets are off.
If no one knows of a "high end" car charger that will not have noise then maybe I should go build one myself. I imagine it'd sell pretty well, I can't be the only one who wants this.
