Delta II, Dual Flow: which device gets the mic?

[alehel]

I've been using my Delta II headset for work lately as I really enjoy the ability to combine sound from my computer and my phone. However, I'm having a hard time figuring out which device gets the mic. Sometimes, when I'm in a meeting on my PC which is using the 2.4ghz, I have a little background music playing from my phone over bluetooth. This worked well most of the time, but then a couple of times, the mic seemed to have switched to my phone instead. I know the mic can only be going to one device at a time, but I can't seem to see any info about which device gets priority, how to change the device while connected to both, or even how to know which one I'm currently sending the mic to.

Also, why isn't the Delta II in the list of "Associated Products" here on the forum?

By default, microphone input prioritizes the 2.4GHz connection if the Bluetooth (BT) is not receiving any call-related notifications in DualFlow. 

Under normal circumstances, the microphone input will not change to BT unless the BT-connected device is receiving a call-related event.

If the microphone input is switching when you are sure there are no incoming call-related notifications from your BT device, please make sure that your headset and receiver firmware are both up to date in Armoury Crate's Update Center.
