iPhone7 has canceled the traditional 3.5mm headphone jack, to use the lighting headphone jack. And for the convenience of users, Apple also provides a Lightning-3.5mm adapter.
As early as before the release of the iPhone 7, Apple canceled the 3.5 mm headphone jack, which has caused a heated discussion that integrated the audio output function to the lightning jack. And different people have different opinions of it. In fact, it is not a moment of mind that Apple pushes this standard, maybe this is the plan from the birth of Lightning.
Apple thinks that the 3.5 mm headphone jack is the last century technology, but because of the long-term use of the formation of habits, the majority of users seem not ready to eliminate the technology, many users are accustomed to use this interface to listen to songs. But on the other hand, this is actually a good news for us to adapt the lightning adaptor. In some sense, this measurement does not affect the usage, such as transfer files to iPhone, use iTunes in the computer, download something to iPhone in the computer through the USB cable.
Let's have a look at this adapter first.
Basic informationOne is the 3.5mm connector and another is Lightning connector on this adapter. Apple has designed an integrated circuit that incorporates a digital-to-analog converter DAC and an amplifier, as well as the corresponding analog-to-digital converter ADC.
In fact, the audio accessories need to require an analog signal to work properly, such as headphones, but unlike to the typical analog headphone jack, Apple's Lightning connector is a digital connector. So, the DAC can set up a bridge between them. Similarly, the chip also requires a digital-to-analog converter circuit that converts the analog signal from the built-in microphone into a light-enabled interface.
Test ResultThe German computer technology magazine - c't magazine has made the test of sound quality on Apple’s new adapter. To put iPhone 6s and iPad Air as a comparison, compare them to the sound quality of this adapter on iPhone 6s, iPad Air and iPhone 7.
The results showed that its performance is not ideal in some cases, but in general, the performance of the adapter beyond the expectations of many people, to make such a small accessory.
Besides, only use a lightning interface, it not only can make the body thinner but also improve phone’s performance, thereby preventing us from losing data accidently. So, if you encountered such a situation that your phone shutdown unexpectedly or the system crashes, you may get help from some iPhone Recovery Software.
