In last 2 months Apple has given me 3 iPhone XS Maxs after complaining about poor muffled sound quality from the earpiece when speaking to people.... the sound from the same call on the speakerphone or bluetooth speakers are fine.... went to Apple store 5 times with the different phones and they found the first phone's sound coming up bad doing their diagnostics.... yet the next 2 phones came up OK yet the sound quality was still poor.... and they tried everything they could think of, yet nothing changed the sound which seems like the treble is turned completely off and the person is talking through a filter which has never sounded like that with all the cell phones I ever had. You can have the person call on my older iPhone 6 plus which was super clear and then call on this 10s max and they were still muffled.....
An Apple tech rep tried for weeks trying to figure out the problem but finally gave up and I'm stuck with this $1250 phone which I hate cause I use it for my business and half the time I can't understand what people are saying.... I've had other people listen to my phone and they all say there's something wrong with the sound. After going through 3 of these phones in 2 months I have to conclude there is something wrong with the iPhone XS Max and Apple is not saying anything.....
Of course, all the advertising is for music, camera, etc but never anything about the sound quality!! It is STILL a phone, isn't it??
Totally dissatisfied with this phone for the price they're getting for it!!!
