At the beginning of January, Westone released the flagship UM Pro 50 moving iron earplugs of the UM Pro series at CES 2014. Now it has quickly reached the evaluation room. The reason why it is so urgent is because it is a rare non-customized five-unit moving iron. What kind of height can the UM Pro 50 achieve in terms of sound quality, and what changes have been made to the five-unit moving iron earplugs are all concerns.

Looking at the UM Pro series product line, Westone goes directly from three units to five units, which skips the popular four-unit design, which seems to be somewhat puzzling. But in combination with the positioning of the UM Pro series monitor, it is not It is difficult to understand. The increase in the number of cells can indeed provide a better analysis for the moving iron, but to add a moving iron unit to the low, medium and high three-way frequency, the balanced sound required to monitor the earplugs is difficult to guarantee. Therefore, Westone abandoned the 3+1 combination, and the five-unit 3+2 scheme is more suitable for monitoring positioning, avoiding over-prominence of a certain frequency band. This is why Weone skips four units and directly introduces five units.

In order to maintain sound balance, the UM Pro 50 uses a three-frequency structure with a medium-frequency and high-frequency moving iron unit on the basis of three-way frequency, but with the number of units. With the increase, the volume of the cavity is also rising in a straight line. When wearing the UM Pro 50, the swelling of the ear can be clearly felt. After replacing the smaller earmuffs, it is slightly comfortable. In fact, before the moving iron technology is not much breakthrough In order to enhance the analysis, the heap unit is also helpless, sacrificing the wearing comfort of the earplugs.

The so-called unsuccessful, sacrificed comfort, five units for the UM Pro 50 to bring analytical improvements? The answer is yes. Deliberately added IF and HF units on the basis of three-way, making UM The Pro 50 has a richer amount of information on the medium and high frequencies, and the overall sound is characterized by high density. No matter which song is played, the sense of hearing is very strong.

If you compare the UM Pro 30, you can clearly see that the UM Pro 50 resolution has made great progress. Although the UM Pro 30 belongs to the previous generation monitor flagship, first of all its sound is still very slim, the difference is in the connection. Avid Mbox professional audio interface is particularly prominent. And UM Pro 30 is still a little warm in the sound, vocal soft and good, high-frequency with a bit of sharp, bass dive depth, high-pitched high-spirited. Although its sound It won't be accepted by most people, but this sense of fierceness is also a feature of UM Pro 30.

Looking at the UM Pro 50, it is still a balanced, neutral voice, but the feelings of the music are further declining. At the same time, the mid-high frequency is never full and thick, as if it were uncut eucalyptus. When listening to music, purely feel The amount of information is pouring into you. The high-pitched sound is high but not sharp. The middle sound is thick but not close. It keeps the middle and high frequency not too much. In the dense information atmosphere, both vocal and instrumental performance Observing the duty, there is no rush and high-spirited voice, full of sound and no impact. Although the UM Pro 50 enhances the intermediate frequency and high frequency performance, the overall sound still conforms to the idea of ​​monitoring and balancing, and the low frequency is not weak. It is a popular dance music that is passionate and passionate. It is also a lyrical song in the middle of the board. The interpretation of the UM Pro 50 on the bass is extremely natural and thick. The continuous drum sounds are restored to the leisurely, without any slight muddy water.

As a predecessor and current UM Pro monitor flagship, UM Pro 30 and UM Pro 50 represent an analytical height in the same number of units. The similarity between the two is to "snap" the second understanding of the song as much as possible. Converting the energy generated by high resolution into high-reduction, not pleasing to the sound. The difference between the two is that the UM Pro 30 is not enough to support a high level of reduction in a three-unit position, so in real time Still able to feel a little dye. And the UM Pro 50 is different, with a five-unit blessing, can further enrich the analysis without relying on later tuning.

So no surprise, the sound of UM Pro 50 and UM Pro 30 is very different. The former is simple and straightforward in the expression of songs. There is no gorgeous rhetoric. It is to use a wealth of knowledge and information to attack you. Need emotions, when the emotions of the songs you hear are the emotions that the singer wants to express, listening to the earplugs completes its mission. So it may not be surprising to hear the UM Pro 50 at first, because it’s The resolution is quite high, but the sound is very cool and boring. It is also very simple to modify the "transparent" sound of the UM Pro 50, with a player with its own characteristics, because the UM Pro 50 is " "Transparent", what kind of tone is the player? What do you like to listen to with the iPhone? No problem, the iPhone has a clear pop tuning, and the earbuds are easy to drive, but the resolution is not so high.

Obviously, the improvement of the sound quality of the five units is obvious. The high density of the UM Pro 50 sound is the iron proof. As the UM Pro monitor series, the earplugs achieve high restoration under high resolution, and the emotions of the songs themselves are conveyed to be true and delicate. The unit has advantages and disadvantages. The increased cavity volume affects the wearing comfort to a certain extent, and it can be regarded as the tang of multi-unit moving iron earplugs. The standard retail price of 4998 yuan is really scary, in order to obtain the two units of the plus Cheng, UM Pro 50 is almost twice as expensive as 30, or a 3980 yuan for a certain e-commerce starter special conscience. In addition to improving the sound quality and increasing the volume, the most intuitive is the price increase, it is really mourning.
