Those who have QQ Green Diamond can indeed hear lossless sound quality music. Everyone knows the effect of a song entering the ears. In fact, there are three variables at play:

The first is the song file itself, whether it is a lossless music file or a compressed music file. The difference between the two is that compression The music files of the music file roughly remove the sound waves of frequencies that are inaudible to humans, but the frequency range of sound waves that everyone can hear is different. Some people can hear some high-frequency or low-frequency sounds, so this type of people You can clearly distinguish between lossless sound quality and compressed sound quality. People who have high requirements for music do not like to listen to compressed sound quality music.

Then there is the decoding ability of the device. Music files are also data, so the ability to decode data determines whether the music file can be displayed perfectly.

The last thing is the playback equipment. This is very simple. There is a very obvious difference in the music effect played by a good headset and a street-market headset. Ordinary people can clearly distinguish between them. A good car The effects of music played by audio and ordinary car audio are also different.

If Heyunjing CM51 dares to be equipped with QQ music that can play Green Diamond lossless sound quality, then its decoding ability should be good. I don’t have a particularly good car audio, so I will give it a try and compare. After taking a look at the same section of the same piece of music played by CM51 with QQ music standard sound quality and lossless sound quality, there are still some differences. This point really deserves praise for this device. It has achieved a breakthrough in technology, allowing Internet of Vehicles products to also Supports lossless sound quality playback.
