Reports about this problem are very seldom though, under 100 cases from a production of million units. Nevertheless, it sounds similar with an earlier problem experienced by the newly released iPhone 8 and iPhone 8 Plus models. Early adopters had reported a similar static noise, in the same front-facing speaker. However, in these cases the crackling occurred only during phone calls, while the iPhone X issue surfaces for any type of audio playback, no matter if its the voice of your conversation partner during a call, listening to music, playing ringtones and more.
In the cases of the iPhone 8 and iPhone 8 Plus crackling earpiece, Apple acknowledged the issue and provided a software fix in the release of iOS 11.0.2. It’s unclear yet if the small number of iPhone X units affected are experiencing a hardware problem with the front-facing earpiece, or the issue is software related too. Apple is yet to release a statement regarding this subject. Stay tuned! We’ll update this article as soon as a fix is provided!
Conclusion: If the iPhone X cracking earpiece sound is hardware related, there’s no way you can fix it. Bring your device to an Apple Store and ask for help. You can book a Genius bar appointment via Apple Support app for iOS. You’ll most probably receive a replacement unit, free of charge, without needing an AppleCare+ plan.
Else, you have to wait for an upcoming Apple software update that will include a fix for the static noise!
