These are the only MP3 recommendations. Sony A844 M10 IPC. These three can be used on your desktop for about 2000. Among them, M10 should have the best sound quality. The digital flavor A844 and the popular flavor IPC are light flavor

There are many kinds of earplugs, let’s introduce them here

ER4P: low resistance, not high sensitivity. Although it is said to be a product that Etymotic compromised for direct promotion, it is not just any one. You can play it with an audio player. The sound orientation of 4P is similar to that of its counterpart, 4S. 4P is a little more mixed, and the high frequency extension is not as much as that of the well-promoted 4S, let alone 4B. The 4P has more low frequency than the 4S, but the depth is not as deep as the 4S. The sound field positioning is not as good as 4S. He is quite an omnivore, good at NEWAGE, string music, and female vocals.

ER4S: A stopper with medium, low sensitivity and high resistance. If you are a newbie and don’t have enough thrust and control, good sound, and a clean sound, I don’t recommend playing ER4S, let alone ER4B. The high frequency extension is fierce, and it belongs to that category. The kind that will give you goosebumps when listening to extremely high frequencies. I have only listened to a portable earmuff B&W P5 that is more powerful than it. . . The background is black, and the low-frequency dive is okay, but the low-frequency elasticity is not enough, and the vocals are not concave. It is in a very reasonable position, and it is good at the same as the 4P+ small system.

SE535: A flagship product that is quite controversial in the forum. It has very distinctive features. The vocals stand out, and the female voice is especially nice (not as "nice" as the CK100, which will be mentioned later). The male voice is just very nice. Nice to hear. The horizontal sound field is very wide, but there is no vertical sound field. . . Although the vocals come forward, the instruments are not completely separated from them. Sometimes the instruments and the vocals fight, and you will not hear them clearly and they are mixed together (only sometimes). The plug has almost no low frequency, the dive is okay, and the elasticity is very good~QQ.

E5C: It’s so old. Most newcomers don’t even bother to buy the SE530, let alone the Big Five~ and the new Big Five is already hard to buy. It is a plug with high sensitivity and high resistance. It is also difficult to push. The vocals are excellent. It is the kind of moving iron that impresses you with emotion and atmosphere. It is a style rarely found in moving irons. Unfortunately, the extension at both ends is not enough. It is controlled by the best human voice. I feel good. As for the tangled wires, they are part of the legend~ Newcomers who want to be nostalgic and like vocals can go buy a second-hand one for collection.

W4: The first civilian four-unit flagship of the era. Unfortunately, once you own it, you can only dive in the jar (just kidding~ There is really no movement in the jar for W4~) , the direct push is actually not a very good plug. It listens to male voices very well, female voices are better, but not as good as 535. The sound is a bit like a dynamic coil, the sound field is not big but very regular and three-dimensional, the horizontal and vertical directions are moderate, the sound field is like a small IE8, musical instruments The distance and near position are very clear. It is the kind of sound that is not amazing to one ear but you will realize its quality slowly after getting used to it for a long time. The sound field quality of 535 is far inferior to it. The shortcoming is the high-frequency extension, which is the same whether it is on or off, and it is not as good as UM3X. . . The improvement after playing W4 is quite large, and the energy and sound field are clearly and audibly improved.

UM3X: WESTONE’s flagship before W4, a successful product. It is not outstanding in any aspect. It has no characteristics. However, this product cannot take the first place in any competition. The stopper will meet any of your needs, because to be fair, it is enough. If you can accept its fake appearance and don’t want to invest too much in the stopper, it is right to insert the movable iron into it~

CK100 : Since I’m used to hearing about moving irons like 535, W4, and TF10, I don’t have a good impression of this Japanese flagship with a strange distribution of three units. The sound is wrong (it’s just a monster). I heard that the CK100 is compared with other stoppers from the Tie family. It can only be regarded as the elegant type, so how sexy are the other stoppers! ? The human voice is relatively scattered, and the main line of the sound is difficult to follow. The entire small sound field is full of scattered filaments and reverberation of the human voice. Some people may enjoy this kind of human voice and think it is dyed well, but I don't like it. It sounds like The human voice I heard when I was drunk and hallucinating, I can be considered a semi-ACG addict, and I still didn’t feel there was anything poisonous about it when I listened to ACG with it. . . There is less low frequency, not much quality, and the high frequency extension is not great, almost the same as the 535. . .

(Why do you think I’m here specifically to hack CK100~~~Sorry)

TF10: It is definitely the most popular three-unit flagship in the forum, and its most famous feature is the tragedy of wearing it ( Just kidding~) In fact, the human voice is not concave. The whole sound forms an arc surface in front of you, and the human voice is evenly distributed on the arc surface. It sounds very comfortable, but it is because when listening to some music with strong rhythm, The instruments performed by TF10 are so brilliant that they will draw your attention to the background. The sound field of TF10 is large, but not regular enough. It is not suitable for listening to large arrangements and scenes. I think TF10 is most suitable for listening to MJ and Sister Bu~

IE8: The most controversial plug in the forum. Those who like it like it very much, but those who don’t like it will throw it away in the second-hand section after buying it. . . (So ??newcomers, remember not to believe in poisonous articles~) The sound is very different when the bud is opened and when it is boiled. I really don’t want to hear it when the bud is opened. It’s a bastard. Turning the low frequency to the minimum is too much. It’s a plug that is completely opposite to the 535. The human voice is so far away that it affects the singer's performance. . . Mine is not yet at the 2,000-hour level, it is only 3,400 hours old. It is the kind that is naturally cooked. Now the vocals are much clearer, a little farther away than the TF10's vocals, and the low-frequency content is more restrained. The background is just a little blurry, keep up the hard work~! The sound field of IE8 is actually not as big as mentioned in the poisonous article, but its positioning is very accurate, and when listening to classical music, it has a sense of a hall and a regular sense of boundaries. You are in a closed space like a hall and close the door. There are only beating notes around - combined with the magical enveloping feeling of thick and solid low frequency (commonly known as Senhai sound), it is really necessary to buy a portable classical music controller!

IE7: In addition to UM3X, I ceremoniously recommend the plug-in for the first time, the dynamic pop flagship~ If you don’t listen to classical, if you like dynamic, if you basically only listen to pop, then IE7 is really great It is necessary to recommend ~ Although people say that IE7 is balanced, but I am used to hearing the voices of moving irons such as 535, I would like to say that compared to the popular performance of moving irons, IE7 is actually quite rich and has strong low-frequency support and is popular. It has a strong sense of atmosphere. Compared with IE8’s front-facing vocals, its pop expression and appeal are top-notch~ (Forget it if you’re a fan of low-frequency head control)

M5 (MG7): The three-section set I brought during the audition , the sealing is not good and the sound leaks, I can only talk about it a little bit. The FS plugs are still not very "civilian", and the listening experience is not attractive. The excellent low frequency combined with the dry listening experience is not my cup of tea. . . (I’m not criticizing it, I really didn’t wear it well at the time, sorry)

FS1: A relatively unpopular little plug in the FS family, the favorite of low-frequency short sellers, the low-frequency one is surging, like the Qiantang River The waves are coming in a steady stream, which makes people with light taste like me frown~~~

EXK: I have to say that Sony still has a lot of technological background, and it can update its product line according to the situation. Such a quality monster is created~ If W4 is a moving arm with a somewhat moving coil sound, then EXK is a moving arm that retains some moving coil characteristics and is covered with dynamic technology. Among these flagships, EXK is the first choice for sound quality. In terms of listening experience, everyone has their own preferences, so it’s hard to compare~ High technology, futuristic appearance, tangled wearing, high quality, high listening experience, luxurious packaging and accessories, and a superior price, this is Sony’s flagship~ The voice was a little reserved, and it sounded like: I am a civilized person, a high-level intellectual, and I cannot express my feelings freely and freely. I should just look at the world with a cold eye and do my work easily without a wisp of dust and smoke. This feeling. This feeling can only be felt after listening to it. It’s really hard to express. The resolution is really high, but it’s still a little inferior to some moving irons. The three frequencies are very even, the low frequency is slightly tight, excellent dive, excellent rebound, people The sound is neither far nor close, the high frequency extension is good, and the overall sound is cold. If you want to be omnivorous and listen to everything in one step, the player's thrust is pretty strong. If you don't want to make a big fuss, just use it to reduce the fever. Basically, if you have a fever again, you can only customize it. . .
