That recent trend of gadgets ditching the headphone jack in favor of thinner, more advanced ports? Like it or not, it's going to continue for a while yet. Intel is proposing that companies use expanded USB-C audio support to "eliminate" 3.5mm audio on mobile devices. It's not just about removing the bulk of a narrow-purpose port, either. As with Apple's Lightning audio, this would increase the use of digital sound and encourage smart headphones and speakers that handle more audio processing (think built-in DACs and improved noise cancellation). They'd even support upgrades, so your headphones might learn new tricks as time goes on.
