Which one has a greater impact on the sound quality of music, mp3 or Customized Headphones?
Music files, the main control IC and In Ear Earphones used by MP3 have an impact on the sound quality
For example, if you use lossless compressed music such as ape or flac, the effect will definitely be slightly better than MP3 with a lower bit rate. Of course, this is good, not only the music itself is good, but you also need to use a slightly better MP3 and headphones to hear the effect
The main control IC used by MP3, good and bad, there will be some gaps in the effect. For example, if the main control of Philips and Samsung is used, the effect is usually better than that of Actions, Zhongying, and Ali.
How can a novice distinguish between 9U and 6U earplugs? A simple way is to turn the MP3 volume to a fixed position, such as two-thirds of the volume, and then use several earplugs in turn. Generally speaking, the sound is louder. The sound of all kinds of instruments is quite clear, indicating that they have high sensitivity, usually 6U, and the sound is smaller, usually 9U. If only the vocals are clear and the music is poor or broken, it is generally 12U. Other evaluations from the price and more factors are not suitable for ordinary people, so I won't say more. Note that when listening to music with a 6U speaker, generally turn on a lower volume, and the sound of the background or musical instruments can still be clearly discerned, while for a 9U or almost loudspeaker, the sound of those instruments may sound more appropriate. 。
To listen to good music, in addition to decent equipment, it is more important to choose a quieter viewing environment without external noise, so that you don't have to turn up the volume to listen to songs, which is more helpful for healthy hearing. Playing at high volume for a long time in a noisy environment will affect your hearing, so you should avoid it as much as possible.
If the general requirements are not high, choose an ordinary MP3, generally domestic solutions are no problem, such as 50 to 80 yuan for MP3, or 20 to 50 yuan for the card, plus a genuine 6U with washer Earplugs are enough. This kind of general wholesale is mostly 6 to 15 yuan. Because this kind of stuff is not often bought, the price will be doubled to five times. As for music, you should pay attention to it. If you choose MP3, it is best to choose a bit rate above 192K. If possible, transfer the original CD to MP3 or use APE, flac format files to transfer, why not directly use APE, flacs, etc. As for the files, because their volume is a bit large, one song can hold 5 to 10 MP3 songs, and another reason is that some MP3 players cannot play this format. More importantly, because of the high bit rate, decoding power consumption during playback may be a bit larger than MP3 (personal guess)
