    A simple google search did not come up with results, so I apologize in advance if this is common knowledge and I did not dig enough to find the answer.

    When I plug my phone into my aux cord in my car the volume is always at max - the last setting I had it at in my car. When I plug it into my headphones though it is at the same level I previously had the volume at when using my headphones - a level that wont make my ears hurt. This is exactly how I want it so that the volume isn't blasting in my headphones when I plug them in and start playing, but how exactly does my phone keep track of this?

    The iPhone can recognize different cables. Your car aux cable doesn't have a mic while your headphones probably do. Look how many "rings" are on both your headphones and aux cable. The aux cable should have one less ring.

    Ah that makes sense and is exactly it. Thanks! I had always wondered how this was done.
