If two MP3 players have no sound effects, will the sound quality be the same?

Please don't "take the core as the center". If the chip is good, the circuit is bad. Philippine core is very good In IRIVER's IFP series, I used 780, which is very good. I usually use BEOSOUND 2, which has the best sound quality in the world. Of course, I also have Kenwood's hard drive. If you want to talk about IAUDIO, I suggest you buy U3.

According to the landlord's meaning, I think the landlord likes to listen to something light, not sound and dye. It is recommended to replace the plug and use E4C.

Let me give you an analogy. It's like listening to music with a strong bass. If the drum sounds, it will keep shaking. If it rumbles, it will be powerful. If it is collected neatly, it will show that the sound dyeing is small and the low frequency is the quality. Of course, everyone likes good texture. If you need quality and quantity, you will spend a lot of money on earplugs. If your P3 is 1000, then the plug must not be lower than 1000. It can be said that the price of sound source should be the same as that of plug.
