A:Answer It will connect to two at a time but there's a bunch of irritational and annoying caveats. For starters, if my phone is connected and I turn on my surface pro 7, the surface will connect also. But if my surface is connected first, then my phone won't connect.
Also, if no devices are connected and the headphones are off, but, I have my surface pro and phone (oneplus 7 pro) powered on, when I turn on the headphones they connect with priority to my surface pro and will not connect to my phone.
I love these headphones but I absolutely hate how the Bluetooth works.
