I have a Samsung galaxy s10+, and I have bought lots of different earphones before. Almost every single pair have done the following things. If I’m on YouTube they will pause, play and skip videos without me touching anything, they will randomly turn my volume up by 2, and a thing the earphones do is if you hold down the button on the earphones, they will make a little ding noise and tell you the time, and pause any audio whilst doing it. The earphones will do this even without touching the button. As I said before, this has happened with multiple pairs of different branded earphones.
