I have a pair of jaybird bluebuds x Bluetooth headphones. I've been using them with my old phone the galaxy note II. And they work flawlessly. However when I try to use them with my IPhone 5s they don't show up when I turn on the Bluetooth on. I've tried restarting both the headphones and the iPhone. I've also looked to see if the headphones had a firmware update which it doesn't. Is there anything else I can try?
