Hi Abs,
yeah it is a royal pain in the a** you will have firmware 1.1.12 on tie beats, you can easily cinfirm this by opening the uodater app on your computer, when click to update it it opens the web browser and checks for updates, however if you open the uodater app you installed originally (should be running in the system tray, or you can open it in your programs list) it will show the current version in there, but I'm pretty sure since your having the same issue as many other are then you are running 1.1.12.
9.3 beta holds the cure for the issue, I have been running it for many weeks now and not one single drop since I updated, so I'm pretty confident it will sort your issue out, do not fear either the 9.3 beta is in version 3 now which is the final version before it final release and doesnt have any bugs I have encountered yet and seems pretty stable, the final release should be some time mid next month (March) and your phone will automatically pull the official release when it's available.
at least with the 9.3 beta you will be able to actuallt use your headset as they should be used, I think apple have been quite bad with handling this issue, I still haven't had an update since my last post when I lasted them for an update. but at least we have a solution now, although I would still like to see an update for the beats headset itself so we know they are still suporting our very expensive product.
cheers,
Jason.
