Why Apple’s headphones have extra holes in them !
These holes aren’t there to please your aesthetic senses and they are not there to save $ 50,000 for Apple by saving plastics either. And if you’re thinking they act as a Microphone, it’s not true either as the microphone is right there where the volume buttons are.
They’re there to make your music sound great.
A speaker works by vibrating a cone with an Electromagnet. This pushes soundwaves into the air, creating noise. But the cone’s vibration can build up pressure, which makes it harder for the speaker to vibrate. And Apple solves this very problem by carving out those holes.
These holes let air flow in and out of the speaker, which prevents pressure from building up allowing the headphone’s speaker to move more freely. This ultimately helps to create better acoustics and deeper bass sounds.
