Oh man do I hope that this firmware update makes my QCII headphones usable again. Hopefully this update fixes the disconnect/reconnect problem I and so many others have been experiencing with these.

I have installed the firmware update.

 

I have never had the disconnect, reconnect issue. So i can't tell if it is fixed or not.

What i can tell is that my issue with it not detecting where the sound comes from if i have 2 devices connected at the same time is NOT working.

Everytime i turn on my headphones and it automatically connects to both my iphone and my macbook, if i play sound from spotify from my phone the headphones are dead. I need to go into the app and manually disconnect the laptop, because the headphones cant distinguish which is the primary sound source.

Really, really, REALLY annoying.
