Yeah, but people play games on their phones, and video syncing to wireless earphone latency, is extra software that the app has to work around.

And all this, because some industry leaders want to extort you for 50 extra bucks for headphones, instead of putting the 0.70 cents jack on your phone.

The point, is the senselessness of the inconvenience the customer goes through, not how big or small the inconvenience is.

It's proof the designer doesn't have your interest in mind, and will take active steps to make your life worse, big or small, if they can get 10 more bucks out of you that way.
