Nothing. The question is, who is going to win: the legion of teenagers and young adults who listen to audio via the headphone jack, or device makers? (It's the legion.) If you had a replacement that was better - cheaper, less of an annoyance than $5 headphones plugged into a cheap phone - then you might win. But the proposed replacement is superexpensive, battery-powered wireless headphones. When the no-strain-relief Apple cables break, probably within weeks, you're supposed to buy another superexpensive set. That's not going anywhere with the horde of teenagers. It's a non-starter.
