I think your analogy to DVDs doesn't work because DVDs were never really about software. They were and, to the extent they still exist, are about multimedia in your living room. They began to decline because of Blu-ray, not because software suddenly became digitally packaged. Second, DVDs were and are an inferior technology with a better alternative in every category of use. Yet when it comes to headphones, I own a pair of very expensive monitors that I use with lots of different devices. Am I supposed to just ignore that investment in the name of an Apple branded phone? There's nothing wrong with them at all and they far outperform a $150 pair of bluetooth "AirPods". Regarding your statement about the Bluetooth being a universal solution, you're offering a red herring. Bluetooth was always available, so if someone wanted that, they'd have used it already. The issue here is the port itself and in this case, that means adapting all hardware not just to a new plug, but to a PROPRIETARY plug that won't work on my PC, digital piano, stereo amplifier, car auxillary port, or any of the other music producing devices I own. That's insanity.
