In my years of using the iPhone since the original iPhone launch, I’ve never once blown the speaker.

Send your phone to Apple, they replaced mine (Europe) cause this is a massive quality control issue, if you check the forums it has been reported previously. I even checked the store models, all had the same problem, from normal Iphone 15 to the Max Pro.

Test your phone with this song https://youtu.be/G5xSLbYMr-I?si=r0U_wDIhrG39ZlIi 1st 10 seconds it will rattle like crazy.

This is not supposed to happen. It should be functional even at max volume

I’ve owned iPhones since the beginning, I’ve never had that problem. If its happened to you 3 times it’s almost certainly something you’re doing to break them

Been using iPhones since 2010… I.e 13 years … never once had this problem.

Send us a video of how the phone sounds

This is a “you” problem, not an “iPhone” problem.

I’ve found that when the speaker holes get filled up with crud, it can cause the speakers to sound like they are blown. Have you checked your speaker holes are clear?

I blast death metal at max volume on my iPhone every day and I’ve never had a speaker blow out. They tune the volume controls so this doesn’t happen so I’m not sure what you’re doing to cause this but it has to be you if this is the third time.
