Yes it does, awesome to be a part of a forum where people drop knowledge like this.

Most of this stuff is over my head so I'm going to ask a dumb question. A lot of the time I'm playing music through Pandora and I know the app has a setting where you can increase the quality of the music but if you do it drains the battery quicker. If I have it on the poorer quality setting could that be a culprit of the hiss? Again, probably a dumb question.

Also, if I get one of these so-called line drivers, will a standard aux male-to-male cable be sufficient to carry the power? Or do I need to purchase one that is higher quality?

It is an iphone, btw, don't know if that matters.
