A small number of iPhone 18 Pro users are reporting an issue where the speaker sometimes 'pops' or 'clicks,' describing it as a faint sound when doing things like switching apps or adjusting volume. Mac Rumors spotted reports in its forums and on Reddit. There are enough of them to indicate that it is a real issue, but few enough to suggest that it’s not widespread.

One user described hearing a popping noise from the upper or lower speaker, similar to pulling out an aux cord, occurring during app switching, volume changes, or voice dictation. Reports of the variables involved don’t point to a consistent pattern, and some are suggesting it may be software rather than hardware related. The issue has not been widely confirmed across devices.
