It has a lot of advantages:

When you have nothing to do to pass the time, you can always travel a long way to visit the mountains and rivers, or get tired of travelling, without the company of music. Music can be said to be a kind of stimulant in people's life. It is a good medicine. In short, it is important not to do, and life with music will feel colorful. Nowadays, the headphone market is full of variety, and the product quality is mixed. It also requires a lot of effort to find a good audio quality audiophone. Today, the author has brought benefits to everyone. It is a high-quality audiophone with excellent workmanship. He is the Nero earplug from Sweden's sound by sweden brand, which has been on the market for more than a year. At first sight, this brand will feel very strange. Although this earplug brand is relatively young, it belongs to the prestigious Swedish high-tech industry group Jenving. Jenving Group is also a parts supplier recognized by the Swedish Air Force. Nero earplugs are produced under the supervision of such a company. Before the evaluation, a very detailed brain patch was made. With regard to the quality and sound performance of Nero earplugs, I am still full of expectations for it.

Unpacking&Details:

The packing box of Nero earplugs is very simple, and the color matching of white tone is relatively simple and elegant. The four corners of the packing box are designed as circular arcs. The surface feels very good against the skin when touched by hand.

In terms of materials, recyclable recycled materials are used. The front of the packaging box is marked with a larger brand logo and the characteristic performance of the product. The bottom also has a lock catch design. If you want to open it, you must use a hard object, such as a ball pen tip, which can only be opened by aligning it with the round hole with force. It fits very closely. It can play a good protective role in transportation.

Through understanding, Nero earplugs can be perfectly compatible with the volume control under three different mobile phone systems, iOS/Android/Windows. On the back of the packing box, the characteristic technology of Nero earplugs and the operating instructions of keys in different scenarios are introduced in detail.

When the packaging box was opened for the first time, Nero earplugs were embedded in black foam. In order to better protect the earphones, the concave fixed slot shape was designed into the shape of various parts of the earphones. The earphones were placed inside, and the fitting was very good. In addition to the earphones, there are also six white earmuffs, plus a set of earphones, a total of seven sets, including silicone, sponge and three piece sets, for people with different sizes of earholes to tune. The official also provides the matching Comforttips earmuffs, but users need to purchase them, so that users have more choices in experiencing comfort.

Next, let's look at the details of Nero earplugs. First of all, the weight of Nero ear cavity is very light, so you won't feel pressure when holding it in your hand. The cavity part is made of alloy, and all have reserved exhaust holes. It is also very comfortable to wear it for a long time. The "S" logo on the back of the ear cavity is still very conspicuous, adding a bit of movement.

The wire material of Sound by Sweden Nero earplugs is designed with noodles, which was created by Supra cables; The biggest advantage of noodle design is that it is not easy to knot, so it does not take a long time to sort out the winding in use. It is worth mentioning that the Nero material uses sound level oxygen free homoconductor, Kevlar material and 24K plug. It can also be seen from the selection of materials that the product positioning of Nero earplugs is relatively high.

In terms of control, a three button design is adopted. There is a small switch on the back of the button. This switch is used to switch between Android phones and Apple phones, so that two phones with different system platforms can support the same headset. This is the first time to see earplugs that are perfectly compatible with both systems at the same time. It seems that mobile devices that support Windows system are also under discussion. The ingenious design of Sound by Sweden Nero earplugs really opened my eyes.

Sound by Sweden Nero earplugs use gold plated plugs and adopt an "L" design. The advantage of this is that it is suitable for matching with mobile phones, especially when it is placed in a pocket, there will be no problem of too long plugs affecting portability.

Sound quality test: professional 9mm neodymium magnet moving coil unit, impedance of about 16 Ω, frequency response range of 16-22KHz, sensitivity: 98db@1KHz From the above configuration, the configuration requirements for mobile phones are not very high, and ordinary mobile phones can be brought with them. Hearing sense: the low sound of Nero earplugs is really shocking when they are turned on, so that some of the middle and high frequencies are buried, and the overall sound will feel a little stuffy, so they decide to use earphones; After a period of time, the voice became more flexible, and the middle and high frequency ones began to show their own characteristics.

First, listen to the songs of the female voice. I chose Cai Qin's songs. The iconic voice of the old female voice has its own unique style. Cai Qin's old and steady bass songs sound very emotional. With Nero earplugs, you can fully feel her emotional feelings. The mid-range performance has a good sense of hierarchy and thickness, and there are obvious signs of softening, especially the female voice performance is very smooth and soft. From the extension of the mid-range to the mid-range and high-frequency, Nero earplugs have obvious means to beautify. After listening for a long time, you will not feel tired. The mid-range voice is relatively prominent and forward. If you listen carefully, you will feel that the voice is less than one meter away from you, so the position of the voice is closer to the ear and it is easy to highlight the clarity of details and mouth shape, which is commonly known as the rhythm with larger mouth shape in the speaker system.

The audition song is generally the guitar SOLO in front of the 94 concert version. The low frequency at the beginning also positioned the machine very well, which is the main drumbeat. The low frequency dive is deeper and softer, while the high frequency is thick and powerful, and the voice is very qualitative. In the fluctuation of low frequency to high frequency, the sound switches naturally. Only good earphones can truly present their highlights, and the effect of ENDING cannot disappear with the end of the song.

In the middle and high frequency part, the middle frequency part is more neutral, and the tone dye is a little bit but not much. Generally speaking, it pays more attention to the original output; The expression of male and female voices is still in place, and the conversion is relatively natural and fast; The treble is not harsh and has certain extensibility. Although it is not as pleasant as breaking through the clouds, it still has a good sense of cohesion; In terms of music selection, it is more suitable for rock music.

After 48 hours of boiling, the sound quality of this Nero earplug will be significantly improved. The most significant change is that the low frequency is more powerful. Its cavity is small, but its energy is large enough, and the low frequency ear tremor is strong, so it can dive into place. High frequency is also very natural, and it does not have too sharp feeling. Of course, it focuses on medium and low frequency, especially for hip-hop and rock music.

Summary:

Sound by Sweden Nero earplugs, as a new product introduced into the domestic market, may not fully meet the tastes of Chinese people in terms of sound. A few minutes of listening to Nero earplugs for the first time may make people feel bored. However, the sound quality will be significantly improved after 48 hours of continuous warming up. The most significant change is that the low-frequency is more solid and powerful. The sharp but not harsh medium and high frequencies are also the characteristics of Nero, with a wide sound field. This is of great benefit to some magnificent music.
