> Have people complaining about this ever really given good bluetooth headphones a chance?

I have bluetooth headphones, but I still rely on my wired earbuds if I go running, or if I want to travel light, or for phone calls. And I also have regular non-bluetooth good quality headphones that I like to use (especially when the bluetooth ones run out of battery). For me, it's not only a matter of sound quality, but I find it convenient to be able to plug any headphones without bothering with bluetooth.
