My Iphone 6s makes crackling noises when I plug in earbuds/earphones?

Can someone please explain to me how to fix the crackling noises my Iphone makes when I plug in earbuds. It does not make weird noises when I play it without headphones; but only when I plug something in to privately listen to music and etc.

Added (1). I don't think the earbuds/headphones are the problem because I recently used new ones, but it still makes crackling noises

Your earphone wires or connector may be wearing out. Try another set to see if the noise goes away. You might be able to immobilize the worn-out wire with tape to get a little more life out of the earphones.

The audio jack of your device is most likely the culprit. You need to get it checked at a service point.

The jack and/or the plug could need cleaning.

In many cases, wiping the metal parts of the plug
with a clean, dry paper towel is enough to clear things up.

  • Using iPhone earbuds as both earphones and mic? I want to use Skype on my laptop but my laptop only had webcam but no inbuilt mic. Can I use my iPhone earbuds as both a mic and as earphones? Do I insert it into the headphone or mic input thing? Thanks @Grayson M I meant for using my earbuds for Skype on my laptop. There are 2 inputs, one headphones, the other for the mic. Which one do I plug my earbuds in so that I can use them as earphones and mic?
  • Should I be worried that my charger makes high pitched noises? So I have an IPhone 5c and I recently bought an off brand charger and I made a discovery. When the battery gets near charged and is not being used, the charger emits a high pitched hiss until I either unplug the device, or start to use it. Is this something I should be worried about, meaning could it catch fire or something?
  • My iPhone makes one of my earphones to stop working? Whenever I plug my earphones into my iPhone 3GS it works for about a day, but then will suddenly kill the left ear, you can't hear it if you plug it into any other MP3 player. There's a small crack next to the jack which I think could be the reason why. Is there any way to fix this.
  • My car is making loud noises when I plug in IPhone to cassette adapter? So I have a cassette adapter and I used to play music on my iPad all the time, now I have an iPhone and I'm trying to play music with that but when I plug it in, my speakers start freaking out and sounds like I'm getting really bad static, is this cause of 4g or something? And is there a way to fix it?
