A small number of iPhone 18 Pro and iPhone 18 Pro Max owners report hearing abnormal speaker sounds, including “pops,” “clicks,” and “crackling,” sometimes described as a faint tick. Some users say the noises occur during normal phone use, while others report it happening more consistently or at specific moments.

Reports appearing on forums include claims that the sound is often tied to interactions such as switching apps, changing volume, using voice dictation, receiving notifications, scrolling websites, and using the cellular connection for calls. Some commenters say the issue involves the earpiece speaker, while others describe it as audible near the upper or lower speaker area. Several users also report that toggling Airplane Mode, rapidly adjusting screen brightness, or changing related settings can trigger the sound.

Macworld notes that Apple has not issued a public statement, and says an iOS update may be needed, while also pointing out that iOS 27.0.1 was released for a different launch issue and early feedback suggests it does not resolve the speaker problem. MacRumors adds that there are reports of replacement units showing similar behavior, leaving the cause unclear and potentially pointing to either a hardware defect or an as-yet-unaddressed software bug.
