iPhone X speaker quality issues as users complain of crackling sound

Apple iPhone X users are reporting a new problem on the most expensive iPhone ever launched. There’s a crackling sound from the earpiece speaker and users have posted about this on a Reddit thread. The sound issue joins the list of the problems that include the display not being responsive in really cold weather and a green line of death appearing on some iPhone X displays.
The main post on the Reddit thread by a user dback83 notes the during a call, the iPhone X has a “tinny can sounding, cracking audio..” The post also says there are quality issues with the speaker and the user complains the audio quality is bad even at under 50 per cent volume.”Turn it up to 80-100% and it’s nearly unlistenable,” says the post.
The top comments on the post are also highlighting the same issue. One user posted there is ‘rattling/clipping’ sound during the calls and even when they got the unit replaced, the issue continues to persist. Users are also complaining of speaker distortion at high volumes and some point out there is way too much treble and too little bass.
