I bought my Fairphones XL a bit more than a year ago, and generally im pretty happy with them. But every once in a while, completely out of nowhere while listening, this incredible loud white noise cuts in. It’s so sudden and loud, all I can do is rip the headphones off my ears as soon quickly as possible and press the off button. It’s hard to overstate how loud and shocking this is, it leaves me every time with high adrenaline for minutes because it sounds like a plane comes crashing down on me.
What the heck is this? And how can it be fixed? It occurs so randomly, only once every few weeks, but it honestly makes me want to throw away my headphones and never use them again 
what do you hear? I sometimes (triggered by specific frequencies) get my bose headset stuck at making a very high pitched noise. Do you get that or something else by “white noise”?
It sounds kind of like this, only even harsher/more grating and LOUD YouTube link pink noise. Like the loudest setting possible, and you can even hear it loud when the headphones are off the head.
