IPhone X sounds muffled

Same issue here! Never had this issue with previous iPhones over the years. It has become a real issue as I use mine primarily for work and all I hear all day is that customers cannot hear me. Extremely frustrating for a device this expensive!!

I got an iPhone X through my carrier (Fido, Canada) Dec. 10 and immediately had problems with it as a phone: people complaining they can’t hear me clearly.

I tested the mic and it works A-OK with all other apps (including Voice Memo, Facetime). I sound clear to others in Phone feature when switched to speakerphone – only muffled in Phone app, and only when I switch off speakerphone.

I consulted Apple Support, diagnosed+reformatted the phone with an Apple Store Genius, deleting my backup and running only basic config and latest iOS 11.2.1, tried everything suggested by support, from checking mic for debris / case blockage, to resetting network settings, enabling/disabling LTE voice and background noise filter.

Over 2 weeks + dozens of hours troubleshooting. I finally convinced my carrier to exchange the phone as defective, but I’m having the same problem with iPhone X #2.

Apple urgently needs to review the Phone feature app. It’s clearly a software problem + I see in forums online I’m not the only one, and it’s not restricted to the X – some users of the 8 are reporting the same issue.

I got an Iphone x this week and am having the same issue on all calls. Most of the time I cannot understand the person on the other end. Everything is up to date and I have restarted my phone. Still poor call quality. I have had iphones for a long time and never had this problem

Same issue with my iPhoneX ,when I play music it sounds muffled..I hope apple does something about that

This is a software issue. I do not know why Apple is taking so long to fix this, I can only use the phone in speaker mode because people can not hear me right.

I too am having people tell me I sound muffled took iohonex back to Apple and they said it tested ok so here I am the day after people telling me the the same thing

I was also told it’s a software issue so updated to latest update, Re set it to factory and put a new SIM card it and it has not fixed the problem

I purchased my X in November 2017 and immediately had the same issues. Like you, only when speaking into the mic during a phone conversation. If I were to put this same call on speaker immediately this cleared up. Within 2 weeks of purchasing this phone I was back at the Apple Store in Phoenix while traveling on business and was there for over 2 hours of diagnostics. I was eventually told that the device was defective and therefore it was switched out for a new phone. However, over the next several months I continued to have the same issues, albeit sporadically. I annoyed my wife by asking at the beginning of every call about sound quality. About 1 of every 3 was back to being muffled but who has time to go back and spend another 2 plus hours with a Genius? I certainly don’t. Eventually I had no choice because at the end of the day I purchased the phone to......talk. Now, back at the Apple store in Atlanta for another 3.5 hours I was told that this was a software issue and I was assured that it was fixed. IT WAS NOT! I am now on my 3rd iPhone X after demanding yet another replacement from Apple Support and I am still having the same issues. Apple needs to step up and find a fix for this expensive phone that can’t be used as a phone!!!!!!

Hey

Same issue here. i went to apple store and they tested it and told me there was VOLTE was enabled. i disabled it, even then i was having the same problem from over 2 months . people spent $1000 + for this iPhone X and seems alot of people are having this issue lately..Can apple do something about this??

I have exactly the same isssue. Since upgrading last year to iPhone X I am getting many people complaint that they cannot hear me properly when on calls. Apple, what are you doing about this?

Have you updated your software to 11.1.2?

This may help as well:

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

I had the same frustrating problem. It turned out to be the case. The one i had was a flip from with a magnetic catch. Removed the phone from the case and immediately got better call quality.
