A chemical property is a characteristic of a pure substance that describes its ability to change into different substances. For example, a chemical property of methane is that it can catch fire and burn in air. Physical properties can be observed or measured without changing the composition of matter.
The downsides are obvious: Almost everyone has headphones, speakers, and other gadgets based on the ubiquitous 3.5 mm headphone jack. Eliminating this connection could render these devices unusable, or at least force everyone to carry around an extra adapter. But Apple doesnât care.
Find the right jacks on the back of your computer. There should be two jacks that match the colors of the plugs found on your headset. These jacks may also have the microphone and headphone icon underneath them. Plug the microphone chord into the microphone jack and the headphone chord into the headphone jack.
