No it doesn't change automatically. I have had them for 1 year now and it never did that. Thanks I will try that out! It will definitely be better than changing manually every time.

I tried the example from the github where the app subscribes to the event stream and receives events such as connect/disconnect of devices. however with my HS70 Wireless the connect event is only triggered when I plug the USB receiver, not when I turn the headset on and off. Is there a way that I am missing to achieve this? I wanted to do a program that would automatically set the device as default when turned on and back to the previous one when turned off.
