Apple's new flagship might have been affected by a production failure. Macrumors is writing about users who feel that the earpiece is buzzing and spreading when the phone is at the maximum volume.
According to Macrumors, there are over two dozen Iphone X owners who discuss the issue at the site's forum, but there are also users who expresses concern at both Twitter and Reddit.

The affected telephones give off the crackling sound when talking, video, music and alarm are played. Also, the problem should not be isolated to a specific version of Iphone X or to any IOS version. The latter was the reason that Iphone 8 and Iphone 8 Plus cracked on phone calls, but it resolved Apple with a software update.
Like Iphone 7 and Iphone 8, the Iphone X uses the earphone speaker as the standard speaker to give the phone stereo sound. The problem may be here, according to Macrumors, who sought Apple for a comment.
