Weird, but true: iPhone earphones stop working when I walk into a particular room When I walk into our master bedroom, about half the time, my earphones on my iPhone stop working.  That is, the podcast continues to play (I'm usually using Castro, but it's hard to imagine that's the issue), but I'm getting no sound from the earphones.

It's not the particular phone. It happened with my previous phone (an iPhone 5) and it's happens with my new iPhone SE.

It's not the earphones. I've had this problem with the stock ph earphones nes, a cheap pair of drugstore earphones, and pair of nice $40 third-party earphones.

It's not what I'm physically doing. I keep the phone in my left pocket and on bud in my right ear. But I can do all kinds of activities -- cleaning, laundry, yardwork, whatever -- without this happening.

It feels like there's something about the room itself that causes this to happen. If it happens, it usually happens as soon as I walk through the door of the bedroom.
Do you have a Bluetooth headphones or speaker in your master bedroom that you've paired to your phone?  Perhaps the phone's audio output is switching over to Bluetooth when it's within range.
