Volume Randomly Goes to Maximum with Bluetooth Headset
Please provide more details and possibly screenshots. Is the Ringer on maximum loudness or the 'Volume' on maximum loudness? It would make sense if the headphones respond differently to the 'call' feature than to media, just like the iPhone itself does.

I don't know, it's just a guess based on the little information that you provided.




Please indicate which of these you are mentioning, if not both.
