Audio commentary

Hello, everyone. The meeting will answer your questions. Can Apple headphones be connected to only one iPhone? can Apple headphones only be used by Apple? many people don't know this. Now let's take a look at it.

Answer:

1. If it is an Apple wireless headset, you can not only connect to the iPhone, but also use a smartphone with Bluetooth. If it is an Apple wired headset, you need to plug in the headphone to use it, as long as the phone interface matches the Apple headset. In addition, headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ear.

2. What is the screen of Apple tablet:

3. Since the new iPad, the fourth generation of iPad and iPad Air have adopted Retina screens. IPad's Retina display screen has 3.1 million pixels, which is an advanced and excellent mobile device display screen, which makes everything look clearer and more vivid, with clear text and vivid colors; and photos and videos are full of details. The so-called "Retina" is a display technology that can compress more pixels into a screen to achieve higher resolution and improve the fineness of the screen display. The technology was originally used on Apple's iPhone 4 with a screen resolution of 960640 PPI (pixels per inch), a resolution large enough to make it impossible for the eye to distinguish a single pixel at a normal line of sight, and no graininess when the pixel per inch of the phone's display reaches or exceeds 300ppi. When the pixels per inch of a handheld flat panel display reach or exceed 260ppi, there is no sense of graininess, while Apple's Retina display cannot distinguish between individual pixels as long as the pixels per inch exceed 200ppi.

This is the end of this article. I hope it will be helpful to all of you.
