Mine has worked most of the time but sometimes I have to unplug and replug once pandora is running. I also thought there was an option to tell it to switch in the pandora app but maybe not, haven't had the issue the last few times i've used it.
I had that problem with another pair of headphones. Occasionally I would have to unplug and replug to get sound from them. I ended up buying new headphones for no particular reason and haven't had that problem since.
