Correct me if I'm wrong here, but I think that the audio jack is one of the few cases where an analog port is good because if the signal in not already analog it must be converted to analog via a DAC. If the DAC isn't in the phone, it has to be in the headphones. So, not only do you need to worry about the quality of the headphones, you have to worry about the quality of the DAC, and the DAC needs power. Seems like a few good reasons to not ditch the audio jack for now, especially if you care about audio quality. Also, those that care about audio quality probably have several expensive sets of headphones that are now incompatible with new Apple phones.
