I use a pair of in-ear, noise-cancelling Sennheiser headphones with my iPhone 6S. I don’t know exactly which model they are, but something like the CX 5.00i isn’t far off. The headphones have a little inline remote control which I use a lot to pause and play songs.
The trouble is that about half the time I do so – particularly if a song has been paused for more than about 30 seconds, and particularly if I’m moving rather than standing still – hitting the button on the remote doesn’t restart the music like it’s supposed to, but instead activates Voice Control (with that VERY loud ‘dun-dun’ sound rendering me half deaf every time).
I have Voice Control disabled as described in the answer to this question, and long-clicking the home button on the actual phone doesn’t activate it. I also have Siri completely disabled.
It seems to be a fairly common issue that Voice Control randomly activates itself while music is playing, but in my case, of course, music isn’t playing when this happens. I’ve only been able to find a few other cases where unpausing is specifically mentioned: there’s a post in a MacRumors thread (no answer in the thread) and a previous question here (which doesn’t mention whether Voice Control has been disabled and also has no answers).
I’ve tried changing to the standard Apple headphones – no change. Unpausing using the headphone remote still activates Voice Control if I wait more than 30 or so seconds or neglect to stand completely still.
Why/how does this happen? How do my headphones manage to activate Voice Control when it is otherwise disabled as much as it can be? And more importantly, is there a way to stop it?
