I'm not so convinced about this. It already divides their customers.
I listen to a lot of music, although not by using an iPhone, but iPods. The earphones without a cable will be a hazard. I can imagine, that they can get lost pretty easily and those earphones are expensive, i guess more money for Apple lol.
Btw i'm not sure about these newer earpods, but the older Apple earphones sucked, so i use my iPods with Sennheiser and Beats earphones/headphones.
Now it's not enough that you need to charge the device, you need to charge the earphones too and that will be forgotten sometimes, i'm pretty sure about that. When you would need them, they won't be charged and you'll be pissed. Even if you don't forget to charge them, when they are fully charged, they will only work for a few hours before you need to charge them again. If Apple wanted to make their customer's life more complicated, they successfully achieved it.
Without offering the cable option too, i see this as one step back. Just like when they decided to ditch the smaller phone all together and only make large ones, just to realize that they made a huge mistake, so they came out with the SE.
Sometimes Apple does things, which seem to be rushed, when there would be a lot better place to make a radical change since long years and that's the battery.
