1. One side of the headphone works on some videos and the other side
has no sound?
2. You put out a little bit out of the socket and both sides start working.
3. Apple headphones are crappy, left or right earphones becomes dead
after 1 to 2 months. Replace it!
4. It's hard to get quality headphones, they get entangled in your
feet and snaaap!!!! goes the wire.
5. It's wire flies all over the place when you put out the knob
crashes the things around you. Including the screen.
