I'am looking for a new headset for my new Jolla but I don't know which Headset is fully compatible.. So i assume that any Headset which is compatible with Lumia 610/ 800/ 820/ 900/ 920 will also work on Jolla?! The question is: will also the Volume keys of some Headsets be functional? Do you think the Nokia WH-920 Purity Stereo Headset by Monster will be fully functional with Jolla? Edit: Any suggestions for a good headset?
