Now instead they have to worry about:
- charging stations
- how the headphones identify themselves to the computer
- skype and/or Windows arbitrarily refusing to acknowledge them as headphones during calls
- DRM
- more than 20$ on average price increase
- Security and privacy
It would likely have taken me a full workday to get them up to speed on any security/privacy issues.
As for DRM, not only do I think they wouldn't care so long as their music played, but I'm with everyone who sees no difference between a remote DAC and a local one. (Heck, these folks in manufacturing could easily have disassembled the headphones and put in an analog output at the appropriate point, they had the relevant rework skills -- and that would not trip any phone-internal tamper sensors.)
I suppose I realized this when I saw folks at a former employer's manufacturing department all buying $100 BT headphones... because that meant they could set their phone down and not worry about yanking it off the lab bench.
