It's great that hear that Bose has it sorted out, but it's usually not the case - all bluetooth headphones I tried so far can only stay connected to one device at the time, even if they can remember multiple pairings. So if I switch them on and both my phone and my laptop are nearby, it's a pure lottery which one is going to connect to them - and then I have to manually disable bluetooth on one device to make it connect to the other. It's just a massive pain in the ass to use.

Sennheiser has this figured out, too. My PXC 550 stay connected to two devices at the same time. When the currently active one goes quiet, it'll switch to the other source if that's active.

Works fine with my UE Boom 2 bluetooth speaker as well.

Maybe the devices you've tried were older or cheap models?

The Sony MDR1000X2s can only stay paired to one device, and they're neither old nor cheap. (I was aware of this when I bought them, they noise cancel better than the QC35s for voice.)
