Yeah, that's the other part of this that I wouldn't be happy about if I were an apple customer- bluetooth sound quality is far, FAR from superb. While I DO own a pair of headphones of that variety, the only reason I use them at all is to make my life easier while working out/not destroying the cord like I have so many times before.
Speaking of which, I imagine many users will be stuck charging their headphones daily- perhaps even more if they're anything like mine which top out at 4 hours. Right now it's only a frustration, since I charge twice a week- but having to deal with it on a regular basis is not something I'd look forward to.
That being said, the silver lining I see in this is the possibility that we'll see a major push to improve the quality of wireless headphones. Unless they're using their own proprietary standard, at which point they can get fucked.
