As traditional as I tend to be regarding technology, I'm going to spend a few minutes singing USB's praises.
Wherever I go, I can find several different ways to charge my phone. I can buy a device to charge my phone at any gas station. I can piggy back on a random person's power bank. Most people own at least one nowadays. I can go into any restaurant and if I ask politely, I can probably get access to a free USB port. Many restaurants just have them for customers. Even basic motels costing $40/night offer USB charging. All computers have USB ports, with few exceptions. Nearly all cars made today have them. Every power strip at my employer has at least two USB ports. USB has fulfilled its promise of being universal. I remember quite clearly when charging your phone was an ordeal. That wasn't very long ago.
All external hard drives are now interchangeable. If you have a hard drive with data on it, you can share it with anybody, or you can plug it into most routers. Does anybody remember the bad old days before there was a standard for external hard drives? I do.
What I've seen recently is a further development in USB. Most small-to-medium sized electronics devices are beginning to either be powered by USB or offer USB charging, or both. The devices with USB are often cheaper than their counterparts, because the manufacturer can use cheaper, off-the-shelf components. Even my solar-chargeable camping lantern has a USB charging port, though I can't imagine ever needing it.
The idea here is that it is possible that in addition to all of the above uses of USB, we could eventually add all new headphones to the mix. They're going to be more expensive at first, but it won't be too long before Chinese manufacturers figure out how to make them for a couple of dollars. I do realize that the Type C connector has a different shape, but we're already accustomed to transitioning USB equipment. There is still a small amount of mini-USB equipment but the transition is nearly done. We'll have to do another one, and hopefully it will work out for the best.
I'll be waiting for equipment to start adopting Type C more commonly. I have no desire to be an early adopter, but I feel like this new style of headphones could work.
