I've purchased set of Sony Headphones (WH1000XM2).
They are great, but I can't figure out how to have two simultaneous connections with my MacBook and iPhone. The headphones will connect to either individually but not at the same time. I want to have it that I can listen to music on the Mac, and answer a call on the phone when it comes in. I have tried this with a PC and iPhone and it's fine.
I believe I need to create a A2DP connection on the Mac, and a HFP connection on the iPhone. That's based on the info here - http://helpguide.sony.net/mdr/wh1000xm2/v1/en/contents/TP0001513163.html I've downloaded Apple's Bluetooth Explorer and tried various settings related to "Disable Hands-free profile" and "aptX" but nothing works. I’m at the stage where I’m testing random permutations as I don’t understand the options.
Does anyone know if this can be done? Headphones will be going back if not.
