Under normal circumstances, our ears do not have this ability to distinguish, all we can feel is good and bad, whether the sound quality sounds pleasing to the ear, and when listening to **, it is full of dynamics and no noise.

In order to ensure product quality, the industry formulates different testing standards from the different performance aspects of the product, in order to achieve the required performance effect.

Therefore, if you want to buy headphones, don't care about its performance parameters in all aspects, because you don't have professional testing tools, and you can't feel it just by listening with your ears. Here, I will give you a small suggestion, if you are buying headphones, if you have a lot of money on hand, you can buy brand headphones, which are more expensive, such as Sony and the like, in terms of quality. If the requirements are not high, the general brand can be used, and the performance is not much different.

In addition, what we listen to with headphones, the quality of the sound is also related to the analysis and restoration ability of the body (such as ***, mp5, mobile phones, etc.) itself, such as the poor ability of these **devices themselves, no matter how good the headphones are, the effect is average. So if you don't have high requirements, it's best to bring your *** or something to buy headphones, find a song that you often listen to, find a headphone that you think works well, and make a comparison, I believe there will be a difference.

Let me give you a simple example, the three frequencies refer to the high, medium and low frequencies, where the sound produced by instruments such as piano strings is the high frequency, the human voice is the middle frequency, and the drum sound is the low frequency. Resolution refers to the ability to analyze the music, the higher the analysis ability, the clearer the details of the music, the better, and thrust does not belong to the term of headphones, in layman's terms, it refers to the power of the device, some high-impedance earbuds must have a large thrust of the device in order to fully exert its quality. If you want to hear the detailed parameters with your ears, you can first use different levels of earbuds to listen to more audio discs, and find out the characteristics of different earbuds by comparison.

Bass dive means that for different devices, this device can make audible 20Hz sound, and the other device can only make audible 60Hz sound, then Device 1 dives deeper.

A level is a voltage level that refers to the relative ratio of the amount of electricity at two or more points in a circuit at the same impedance.

Sound pressure refers to the pressure of sound per unit area.

At the same price, different brands of headphones can't say who is better, each has its own characteristics, everyone likes different timbre, the use is different, or it should be different for each person to choose the right one for you, it is best to choose a lightweight one for mobile phones, the sound field of the headphones is better than the earbuds, I don't know what type of ** you like to listen to.

KOSS PP is a classic headphone, the bass is very strong, suitable for metal, rock and roll, and it is very comfortable to wear.

Sennheisel PX200, also a little more bass emphasis, most of the ** are suitable.

Beyerdynamic DT231, this headset has less sound modification, light, and the fidelity of ** is the best, but many people are not used to it, and the workmanship is relatively simple.

Audio-Technica WM55, SJ3 is a best-selling 2 models, the sound is more balanced, and it is more fashionable, and most of them are also suitable.

The most characteristic of the sound here is koss pp, and the other sounds are not very big. If you're really unsure, just look at the appearance and choose one, or try it out. Find one you like.

PX200 has the most fakes, and those with more than a hundred or even dozens of yuan on ** are fake, don't be greedy.

If you still like Senhai, there is generally no suspense in the PX series in terms of headphones. Portable is the advantage,**It's about the same range,Please be careful of fakes.。

If you're not too big, HD205 HD215 can take a look. It may be a little out of the price but the low frequency is sufficient, and the detail resolution is quite good (for **). In addition, this kind of closed-back headphones will isolate the outside sound, so don't listen to it while walking on the road to avoid traffic accidents.

Open-ended, I haven't tried it, so I won't talk about it, and others will add it.

The phone should be moved, at least from the perspective of headphones, these are not difficult to carry.

AKG's K420, I don't regret buying it, ** of about 280.
