Why is the sound quality of the same Android phone so different?

If we just talk about the sound quality test of music playback output, Apple is definitely No. 1 among all mobile phones in the world today

First of all, I remember I said this to others before The reason is that the Android system has the effect of deteriorating the sound quality, and today's Android devices only have DX100 audio, and the code stream bypasses the Android system, so it does not matter. Other Android devices including MIDs and mobile phones have all been deteriorated, and the sound chip is useless. Therefore, the once brilliant Sony WALKMAN series has withdrawn from the stage of competition, and the same is true for Meizu MX M9 and the like.

I saw someone talking about Meizu’s sound quality problem earlier. I can only say, buddy, you haven’t heard of a better machine. It’s hard for Meizu to do better on the same platform as Sony can’t do. At least I don’t think Meizu M6 can have better sound quality than Sony XK.

Let’s talk about Nokia again. Nokia did have many high-level sound quality machines in the Symbian S60 era. Its main control sound chip has a much better reputation than the flying core chip used in Meizu M6, but with the With the decline of Nokia this year and the decline of music phones themselves, the glory of the Nokia series of music machines is no longer there. In addition, after using the WP7 system, it is difficult to say whether Nokia can optimize the sound quality to the level of the year (the sound quality does not only depend on the chip, but also Circuits, as well as firmware, which is the influence of the system)

If we talk about old machines, there are many machines with really good sound quality, but it is difficult to say that today’s fashionable products can surpass those of that era (it is actually difficult to surpass MP3) CD is the same truth, it is difficult to improve the sound quality)

Finally, let me comment on the OPPO of the original poster. If you know that OPPO is actually a brand of BBK, I don’t know what you will think, although this is a fact.
