There's a pretty strong argument to be made that wireless will eventually be better than wired: with wired you're stuck using whatever DAC and analog hardware that Apple is willing to pay for in your teeny tiny phone, and they're all in the massively high noise environment of that incredibly complex device that you've probably dropped enough times to crack a shield of two. Sound will only ever be as good as the weakest link in the chain.
In da future, the DAC and amp will be scalable to your budget and needs and reside in a well designed, shielded housing close enough to your ears that there isn't much of an analog path to be corrupted. It'll be pristine digital until the last possible moment and then converted by hardware of a quality you choose.
