Both me and my partner are having the same issue with our beat studio wireless, we both have have a set and I have got the iPhone 6s Plus and my partner has a iPhone 6 both are on IOS 9.2 and they both do exactly the same thing, they disconnect and very intermittently can be a couple of songs or 3 or 4 and it will disconnect and start playing through the phone and the bluetooth shows disconnected and the beats are still switched on showing as active, however if I try selecting the beats to reconnect on the phone it fails, the only way to get it to reconnect is to turn off the beats and then back on again and it works ok again for another couple of songs, seems to do it more with just Apple music, if nothing is playing and the headset is connected they will remain connected no problems, just appears to be when playing the music and skipping through songs followed by a short pause and then disconnection and then the music continues playing through the phone itself.
both beats are on the latest firmware 1.1.12 so nothing to update here and the iPhones are up to date too!
been looking around and there seems to be more and more threads popping up on various forums all with the exact same issue, some have said updating their beats to the latest firmware has fixed it for them however ours are already on the latest so I'm a little confused there.
fact remains this needs sorting out, we have all paid a fair amount of cash for these devices and now for them to be both Apple products and obviously not tested is quite poor as it seems to have been an issue since the 9.2 update and Apple Music update. I really hope they sort this soon, kind of pointless having beats wireless when they can't be used via wireless connectivity.
I have schedualed a support call from Apple for this afternoon, so I will provide them as much detail as possible and see what they say and try to find out how many other reports they have had for this issue and report back on here!
speak soon,
Jason.
