When Apple killed off the speaker jack its CEO Tim Cook said: "that jack takes up a lot of space in the phone, a lot of space. And there's a lot of more important things we can provide for the consumer than that jack".

OK fair enough, so what did Apple do with the extra space? Well, it turns out that the latest tear down carried out by iFixit found that Apple was doing nothing with the extra space it gained from getting rid of the headphone jack.

It wrote that in place of the headphone jack is a component that seems to channel sound from outside the phone into the microphone. In other words, Apple has not put anything into the space at all, just some acoustic holes, which lead nowhere, and moulded plastic.

We somewhat cynically suggested that the reason that Apple got rid of the headphone jack was nothing to do with providing new functions on the iPhone 7. Instead we see it as a way to prop up its wireless headphone business .

It does appear that the tear down confirms this as it is unlikely that the iPhone 7 needed this fake plastic grill and acoustic holes. It appears to be a rather costly feature for people who will now have to fork out a fortune for new headphones.
