With the release of the iPhone 7 and iPhone 7 Plus, “immersive surround sound” is not the last on the list of important options for new Apple smartphones. However, its implementation misleads users who mistake two pairs of decorative grilles at the bottom of the case for a stereo system. Actually there is no stereo.

Starting in 2016, the iPhone said goodbye to the headphone audio jack – that’s a fact. Instead of the previous round hole, the lower face is decorated with two bars. It is logical to assume that speakers are hidden there, with the help of which a stereo effect is created when the smartphone’s speaker system is operating. Alas, this is self-deception – if we look at the specification on the official Apple website, we will find that behind one (on the left side of the Lightning connector) of decorative grilles there is only a microphone. And behind the second (on the right side) is the only end speaker and an additional microphone.

Stereo sound in iPhone 13, 13 Pro, 12, 12 Pro, 11, 11 Pro, XS, XR, X, 8 and iPhone 7 is created using a speaker located next to the earpiece, located at the top of the device.
When you talk on the phone, an acoustic wave is transmitted to your ear from only one of them, and if you turn on the music at full volume, both devices will work. Twice as much power – twice as loud sound, which is also noticeable when using the speakerphone. Plus, Apple hints that the latest iPhones have “increased dynamic range” compared to older models.

And why then the symmetrical grille at the bottom of the iPhone 13, 13 Pro, 12, 12 Pro, 11, 11 Pro, XS, XR, X, 8 and iPhone 7?
For beauty, literally. More precisely, the perforation was vital for the normal operation of the microphone, so the designers simply added the same pattern on the other side, for symmetry. And there will certainly be lumps of dust accumulating.
It should be noted that with the release of the iPhone XS, the grilles at the end have become asymmetrical.
