Full Answer

Some older phones did have a smaller, 2.5mm jack, but as phone manufacturers diversified into making accessories most of these peripheral ports became standardized industry wide. This allowed for more manufacturers to create devices that were compatible with more phones while making it easier for consumers to purchase the product they needed without having to replace their phone in order to use it. Alternately, some phones and some headset manufacturers allow for USB and micro-USB cables to be used instead.

    How do earphones work?

    A:

    Earphones, or headphones, work similarly to speakers in that they turn electrical energy into sound by using magnetism and the vibration of air. While a large speaker vibrates the air in the space around it to create sound, a pair of earphones only vibrates the air inside the ear canal. Earphones are usually designed as either closed-back or open-back, which affects how much sound can escape from them.
