That's a fair point. Managing headphone battery life has been pretty easy for me, but of course not everyone is the same. Over-/around-/on-ear headphones tend to have pretty good batteries (the bigger size usually lends itself to longer-lasting batteries). In my case, with daily use of a few hours per day, I normally go for about two weeks before needing to charge my headphones, and even then, it's just a standard micro-USB for charging (I use the same cable for several other things anyway). The limitation/hassle with batteries is obviously more pronounced with earbuds / lightweight headphones since they'll require more frequent charging. Apple seems to be alleviating that frustration - at least somewhat - by combining charging with the carrying case. As charging becomes more transparent to the user (or integrated into their routine), the less of an issue it becomes.
