The audition time is a little short. It's only a week, so I can't help it. I get the earphones and audition every night. This earphone is really fashionable. The first thing I feel is that the workmanship is very practical and the appearance is very dazzling. Especially the white appearance is more fashionable. The package of the J55i looks very grand. After all, this earphone is really large and needs a larger package to hold it. Through the front packaging, we can easily see the appearance of this headset, which has a strong sense of technology and a very eye-catching model. The make for iPod iPhone iPad in the lower right corner also lets us know that this product supports Apple's series of products, and has been confirmed by Apple. To ensure the best experience, Apple has formulated special compatibility requirements for accessory manufacturers. All products designed and certified to be compatible will be labeled "Made for" on the package. To ensure compatibility, when purchasing a third-party accessory to be used with the device, please confirm that the accessory has been authorized to use the "Made" associated with the device
Anti counterfeiting mark and certificate on the back.

When I opened the package, I felt that the real machine was more beautiful than the pictures. At the same time, it felt very good. The headset basically adopts three main colors, white, gray and metallic. What surprised me was that there was no wire connection for the headset. At first, I mistook it for a Bluetooth headset. Later, after careful inquiry and observation, I found that there was a wire connection hole under the headset. I believe it should be connected under the package.

First, let's take out the earphones and enjoy them. Let's not talk about the shapes. I believe you are tired of seeing many kinds of earphones. But I have to say that the details of the earphones here are really excellent.

The appearance design of metal wire drawing, as well as the logo of JBL, all reflect the level of workmanship that a large factory should have. Of course, the earphones are of symmetrical design. The elastic sponge on the earmuffs feels very comfortable, and the elasticity is very good. It can bounce back quickly after being pressed. There will be no serious deformation of the rear ear muff after wearing it for a long time like other earphones.



It can be seen that there is indeed a headphone cable jack here for connecting headphones. This design is relatively convenient and easy to save headphones. For example, I have a lot of headphones and often like to throw them together. The wires are easy to wrap together and it is difficult to separate them. It is really convenient to separate the headphone cables and package them separately.

When the package was completely opened, all the accessories of JBL came into view. There were not many accessories. It seemed that there was only one earphone, some paper instructions and warranty cards. It was very simple. A cable clip was included with the machine for easy wearing.

Here you can connect the earphone with the headphone cable. The headphone cable adopts the recently popular spaghetti cable design. At the same time, the color is gray, and it looks very beautiful when paired with white headphones. At the same time, the headphone cable is connected with the headphone by snap connection. The nine heads are directly inserted into the headphone interface, and can be directly connected by rotating it. The connection is tight without looseness, It will not fall off basically. You must manually rotate the connector to separate the wire from the headset. It can be seen that JBL earphone wires are also fine and beautiful. I believe that high-quality noodle wire will bring me a better experience.

The earphone adopts a 9-gear size design. Users can choose the most comfortable gear to wear by selecting the gear. The next time they wear the earphone, they don't need to adjust it one by one to achieve the most appropriate wearing effect.

The J55i earmuff can be rotated 180 degrees. On the one hand, it can reduce the size of the headset and make it easy to carry. On the other hand, it can be worn in one ear and chat while listening to music.


The top screw is fixed and looks more secure.

The biggest difference between the J55I and the J55 is that the J55I supports the voice call by wire function. The orange button in the figure can control the call with one button. The orange button can adjust the volume. Personally, I seriously doubt that the J55I and the J55 are just different from each other because the headset cable is replaceable. If this cable is used, it is the J55I that can talk, while if there is no wire control, it is the J55. Of course, this is a personal guess. Whether this is the case remains to be verified.

JBL j55i is equipped with a standard earphone bag, which is more convenient for carrying earphones. Even as an accessory, this earphone bag is quite well made, soft and comfortable. The earphone bag adopts a double-layer design. The internal wire and earphones can be packed separately. Even if the earphones are not folded, they can still be put in perfectly. But after all, the earphones are a bit large. If they are put in the bag, the overall volume is still relatively large. They still need to be put in the backpack during travel.




When the headset is rotated 180 degrees, the overall volume will become smaller.

JBL J55i designs left and right marks on the left and right of the earphone inner cavity to distinguish the right and left wearing ways. At the same time, we can distinguish through the headphone cable. The ear cavity with the headphone cable is on the left, so that we can easily distinguish between the left and right ears for fast wearing.


Of course, in order to wear comfort, it is necessary to add elastic sponge to the roof beam. It is easy to see from the top beam that the earphone is a metal bracket and is fixed externally with engineering plastics. It should be very firm. For the degree of firmness, see the next chapter.

Appearance summary: The appearance of JBL J55i looks very trendy and fashionable. It can be said that it is a must-have and fashion first choice for trendy people. At the same time, as an enterprise with a long history of audio equipment R&D experience, JBL has a high reputation and rich R&D experience, The wearing comfort of JBL J55i is very good. The details are excellent. It reflects the level of workmanship that a large factory should have. As for the sound quality of JBL J55i, I think it would be better to listen to it with a variety of players. After all, everyone's player is different, and the playing effect will be different. As earphones, the sound quality is the soul of earphones. If the sound quality is poor, no matter how good the workmanship and appearance, the earphones will be eclipsed. How about the music quality of JBL J55i? Listen to the following music players.
The first matching is the first time I was shocked by the small mp3, Alley and ifp395. This classic flying core machine still has many people missing his voice, and I am one of them. This MP3 player does not monitor the general sound quality, does not have super strong analysis, and does not have a particularly broad sound field, but its tuning is very excellent, and the voice is very warm. The bass is surging, but the treble is transparent and bright. The only thing is that the mid-range voice is not thick enough. How about the effect of matching with JBL J55i? Simply listen to some songs you often listen to.

I listened to Lin Junjie's aways online for the first time. This song is my favorite recently. It may be due to Lenovo's aways online themed short commercial. Although it is a dynamic song, it gives me a little sadness. At the beginning, the bass was very strong. After all, the effect of the flying core was unanimously recognized by everyone at that time. At the same time, the instrument is also very crisp, the strings sound crisp, and the position is very clear, strong sense of positioning. The analysis is very good. This MP3 player has never heard such clear analysis before. At the same time, the voice thickness has been enhanced, which is obviously better than the previous earplugs and headphones of a certain brand. The only feeling is that the high-frequency is not as bright as before. It feels a little weaker for high frequency, but the instrument is very crisp. This effect is my first experience even though I have used so many earphones. Aili and ifp series belong to the kind of player with good tuning but not very clean sound background. The JBL J55i feels that the shortcomings of this player are well covered up. Instead, it makes me feel very quiet and clean. The position of the instrument also appears very clearly around. I feel that these two models match very well. In the second song, I listened to Jacky Cheung's thousand reasons for sadness. The first accompaniment gave me a clear sense of direction. When Jacky Cheung's voice came out, I felt a little disappointed, and felt that the voice was slightly behind. In the past, when listening with earplugs, the voice was very forward, just like singing at the ear. This time, the distance is a little far, and the background music is prominent. From time to time from different directions. Some overshadow the feeling of the lead singer. It can be seen that this earplug is a style with many details.
The second model is matched with the last generation of Sony's MD, which is believed that the older generation of players understand that when the MD appeared, the enthusiasts also went crazy for a period of time, and its compact body and excellent sound quality effect were favored by many people. In the era of technological development, mp3 gradually became more popular, and the MD was submerged in the trend of the times. But those classic md still have an indelible impression on the players.

Sony's N920, the last model, was praised and criticized by everyone at the end of its appearance. However, I don't think there is anything special about this MD, but there is nothing special about it. It is most suitable for analyzing the style of earphones. After listening to the music in the MD disc, I felt that the first thing was that the high frequency was much darker. At the same time, the voice thickness has increased a lot, and I feel that the voice is very thick. The crispness of the instrument is also good. The bass is very deep, with good elasticity, and the bass volume is also quite large. I feel passionate. The positioning of the instrument is very clear and the resolution is very good. The sound field is also quite large. I feel very spacious in the surging bass. From the perspective of MD's moderate style, this earphone is very powerful in bass and midrange. The high frequency is slightly dim. The separation of instruments is good and the sound field is large. It is very suitable for rock music and dynamic music. And the singing of small vocal music will be a little dim.
The third matching uses the tablet matching. The sound quality of the tablet may not be as good as that of the two players, but it is more commonly used. Since there is no iPad series product in hand, the domestic five element mini2 is used. In the domestic tablet, the comprehensive level of this model is good, so use it to try.

Even the ordinary tablet audition gives people a feeling of passion. Although the digital flavor is very strong, the voice performance is still impressive, especially the bass performance is still very good, full of flexibility, and deep dive. It feels that the high frequency is a little darker. After all, the high frequency of the tablet itself is not so good. But the sound is clear and there are many details. The music is very strong.
The fourth collocation uses our most commonly used mobile phones. Because I am not so rich and handsome, I can only use Diaosi Xiaomi's mobile phones. However, the performance of Xiaomi mobile phones has also been gradually recognized by most players, whether its system or its music effect can be said to have been accepted by the public.

Personally, the music effect of mobile phones is better than that of tablets, because mobile phones are the most convenient to carry when going out. I am used to the effect of mobile phones. Especially this earphone is certified for Apple series. For better performance, it is mainly used for mobile devices. After listening to several songs I often listen to with my mobile phone, the sound performance is much clearer, and the sense of positioning is better than any previous earplug or headset. The bass effect is very good. The bass is strong, but not excessive. This headset optimizes the mobile phone very well. The bass is in place, the instrument is crisp, and the sense of orientation is strong. The only pity is the same as before. The high frequency is a bit dim, but it is really a good choice for dynamic music players.
Finally, a desktop computer was used for listening. The desktop computer is relatively powerful, but as a mobile device, the J55i is still very easy to push. Here is a simple listening. For players who prefer to listen to music on the desktop computer, you can choose the J55 of the same model. The two products are only different in voice control.

Foobar2000 was not used for audition. Instead, more convenient Kuwo music is used. Now Kuwo music can be easily downloaded to lossless music. Compared with The difference between foobar2000 is not very big, only in plug-ins. Personally, I prefer authentic music to plug-in amplification. Kuwo music is more convenient to use. With the J55I, I found that this headset is most suitable for desktop computers, and the sound performance in all aspects has almost reached a very good effect. The bass effect is very impressive, the voice is very thick, the instrument separation is good, the analysis is good, and the transient performance of the large scene is good. The high frequency is slightly dim, but it is not important, because the positioning of this headset itself is a dynamic scene. I believe that this is also the overall positioning of the True Wide Headset. After listening to it for a week, I always feel that I prefer the performance of this headset in movie blockbusters to music. The earphones are fully sealed. Wearing the earphones seems to be sealed in a music movie environment, so you can carefully taste the sounds from all aspects. In the previous audition, it is easy to find that this earplug is mainly aimed at bass, and has a strong ability to contrast the atmosphere. The contrast of the atmosphere plays a very important role in the film. You have also been to the cinema and seen some foreign blockbusters. The cinema is very good at supporting the performance of bass, roar, and orientation, which will make people feel immersive, I don't know if you feel it is easier to get involved in movies in the cinema. Even if there are relatives and friends around, they will be attracted by the film, and gradually forget to talk. On the one hand, the picture is, I think the voice of telepresence plays a great role. JBL J55i gives me a feeling of being in the cinema, especially when watching some foreign blockbusters. The immersive explosion and roar really make me happy.
<Pictorial 2>1080p likes this quiet little song very much. In the open field, Xiaowei's singing is graceful and moving. It is very open around, and the sound of burning flames is faintly visible. In the whole scene, JBL J55I can restore various details well. And the voice restoration is also quite real, and the scene atmosphere is set off very well. Especially in the middle and later stages of the film, in the war scene, drums are mixed with roars. The magnificence of the scene can be shown through headphones.




"Cheap Bear" 720p is a funny play with a slightly sci-fi color. It looks very cartoon, but it is a very adult movie. There are not many big scenes in this movie, just curious. So I try to see how the sound quality has improved when I watched this movie before. This is a film with small scenes, which may pay more attention to details. For example, when the cheap bear fights with the male lead, the sound of violent falling objects, and when the fight scene changes, their action positions change from left to right, listening carefully is very clear.


Terrain Adventure 2 is a big adventure film. The scene changes quickly and breathtakingly. In the adventure, you will encounter a large monster if you are not careful, such as the large lizard in the picture. When the protagonist and his party pass the egg of the lizard, the egg begins to break. The sound of the crack coming from the earphone makes me sweat, When the lizard wakes up, it roars loudly and runs quickly. Especially when the main character and his party escape, the heavy footsteps of the lizard come from behind, which makes people feel very shocked. I believe that if there is a 3D display with good display effect, the effect will be more realistic and shocking.


Is this Iron Man? Oh no, this is The Avengers 1080p The Avengers Alliance is a science fiction drama with very large scenes. Whether the spaceship is attacked or the final battle, there are gun sounds everywhere, the sound of aircraft propellers, the sound of missile launches, the cries of victims, and a film giant with large scenes. All these sounds are comprehensive. The JBL J55I performs incisively and vividly in these aspects. Almost all the detailed sounds, directional sounds, explosive atmosphere, open scenes, collision sounds and painful grunts are fully displayed. It completely gives the film the atmosphere it deserves. At the same time, it made me more involved in the film. Although I had seen the film before, I took the opportunity of JBL j55i to relive this heroic film.




Compared with music, I think this earphone is more suitable for film and television blockbusters, because it performs very well in details, with a strong sense of orientation, large bass volume and strong atmosphere. It is totally a cinema level earphone for enjoying blockbusters.
