Apple is ultimately looking to move toward an entirely portless iPhone, and removing the accessories — and thereby reducing users’ dependencies on them — is a pretty important first step to doing this.
After all, once people get used to not having the charger, they’re more likely to seek out alternatives, and wireless charging will begin to look more attractive. After all, if you have to buy a charger anyway, why not go wireless?
The same can also be said for headphones, especially considering how many inexpensive Bluetooth earbuds are now available on the market. While these won’t provide the same quality as a $200 set of AirPods or Beats, they’re definitely on par with Apple’s $29 EarPods.
