My JBL wireless headphones left side doesn't work?

This problem only appears when connected to my iPhone X, on other phones both sides work. What could be the problem?

Something might be wrong with the iPhone.

This is an example of using logic to figure something out.

Try it sometime, will ya?

  • Volume buttons on the side of my iPhone doesn't work My volume keys on the side aren't working! Like I can't turn the volume / ringer up or down. Please help! I can't even listen to music without headphones!
  • Left side of my iphone 4 screen isn't working? Nothing on the left side can be pressed! I did a hard reset (pressing the home and off button) but it didn't work. Then i completely reset it, but there's no difference. I don't have an apple store where i live, how can i fix my phone? Btw, i can still do the *slide to unlock* which is odd, considering that that requires use of the screen's left side
  • My normal headphones won't work after using Bluetooth headphones? (iPhone 7)? I've been using AirPods for a couple months now and the battery is getting pretty bad so I decided to get some plug-in Apple headphones but those don't work. When I plug them in I get a "not supported" notification. I've also tried friends headphones that worked fine on there phone, so I know it's not just faulty wires.
  • My left eye hurts when I move it from side to side and up and down? I was on my iPhone last night at 11:00 pm, and I was reading a small print book for class today. When I move my left eye left and right and side to side to look at something, they hurt. I have pretty bad eyesight, an wear thick-ish classes. Is this because I was straining them or?
