I've been using my phone for 2-3 days and have noticed that, when I talk to somebody while holding the phone, the ear speaker is very "tinny" sounding. It's most pronounced on "s" sounds. It sounds like the person on the other end is taking their phone and rubbing it across their pants. It's almost like a static accompanies every sound. Now that I've heard it, I can't un-hear it. I've swapped back to my Xs and the sound is much better. I've tried at home on wifi and out and about on 5G. I've reset the phone and no change. I know all of my ringtones sounded different with the phone, but I had written that off as the difference you get when jumping from XS to the 13pro. Now, I'm starting to think the speaker has trouble. I contacted Apple and my options were to a) have BestBuy crack it open and look at it (no apple store near me) or b) send it to Apple and let them crack it open and look at it. I'm not happy about having a 3 day old phone getting taken apart. They said my final option was to return and re-purchase. I'll either do that or just suck up the sound and trade it in on a refurb through AppleCare in a month or two. Anybody else hearing subpar speaker performance?
