This, so much. I have bluetooth headphone for the gym, because exercising with a cable is a faff. But I hate then. I hate that they run out. I hate that I have to, and often forget to, charge them. From a purely practical standpoint, my year old phone barely holds a day of charge with a little usage. But at least now I'm still able to charge my phone and listen to music at the same time. I listen to music (on fantastic, wired headphones) for about 7 hours a day in the office. I can't imagine a world where I'd have to stop after 5 hours for 3 hours of charging before I could wire in again. Until you can give me phones and headphones that charge by themselves - nay - until you can replicate my current experience, just without the cables, I'm not interested.
