I don't daily drive my phone for commuting anymore, but the trade-offs aren't exactly new: - battery frustrations - cost of a dozen cheap but good quality headphones vs a wireless equivalent - easier to lose wireless headsets when you put them down somewhere (wired too, but way cheaper so less big deal) - audio quality? Who knows

For people that demand noise cancelling, you need an active power source, but I personally hate noise cancellation and always turn them off. Maybe valuable in a plane with lots of engine noise.
