Some Apple iPhone X units facing an earphone bug

Apple issued the iOS 11.0.2 update in October that fixed cracking sounds in the iPhone 8 duo, but now the iPhone X has seemingly developed a similar issue. Users reported a cracking and buzzing sound through the earpiece speaker at high volumes that appears in calls, during video playback or when listening to music.

iPhone X owners now face an earphone bug

One user says a little cracking is heard whenever the volume is at max levels. It was noticed on certain songs and even with a ringtone, bought through the Apple Store.

The sounds may be the result of distortion since they are heard only at higher volumes. Because of the variety of media played, the problem is more likely to be hardware or software issue than a pirated song with questionable quality.
