A friendly evaluation of the ostry bloody besieged city KC06A

When it comes to ostry and the siege, everyone will not be unfamiliar. Although the brand has gradually entered the public field in the last two years, it has gained enough high exposure with only the two KC06 and KC06A headphones. A good word of mouth. I started to pay attention to this brand in the beginning of last year, but I have never experienced it for a total reason. Until recently, I participated in the tour auditing activity of KC06A, and finally I have the opportunity to find out. Because this is this time. The first stop of the tour, so spent a lot of time to take the opportunity, but also tasted for many days, but the mind has never formed a complete impression of the KC06A, and even difficult to see the blood to accurately open, so only I can feel it slowly and bit by bit, and gradually outline the true outline like a puzzle.

I have seen a lot of headphones before, but KC06A's rigorous and chic packaging still left a deep impression on me (although it is basically the same as KC06's packaging, but KC06A is the first siege earphone I have ever experienced), even on tour. The sample of the audition, the official on the packaging is also unambiguous.

The packaging is very characteristic in design style. Unlike the mainstream box packaging, the package of the blood-colored siege is a hollow cardboard box with a black background and a red hot stamping LOGO. The back is rarely marked with a marking method. And URL and other information.

The inner box is red and multilateral, with QR code and barcode on the side. Not only the overall color of the package complements the KC06A, but also the internal structure is patchy. No matter the earphones are placed, the accessories are placed in an orderly manner.

KC06A's accessories are quite rich, including a set of small and small diameter silicone sleeves, a set of tuning silicone sleeves with filters, as well as ear hooks, storage bags and clips, warranty cards and instructions.

In terms of styling, the KC06 drop-shaped metal cavity is particularly eye-catching. The surface is treated with high-gloss, with a gold-like metallic luster. The duct portion is rotated and extended. The "Eagle Eye" and "OSTRY" LOGO are distributed behind the earplugs. Shell and cavity.

The screen on the unit is closely arranged, and the entire earphone is tightly sealed.

The wire and unit are connected by a black rubber handle. The black transparent wire is integrated with the color of the cavity. The splitter is designed like a tree stalk. The plug is a three-stage gold-plated straight plug.

Although the shape of the KC06A has not changed from the previous KC06, the color matching is more fresh and bold, and the all-metal cavity under the black and red color is relatively easy to read. It is easy to put into the ear when wearing, but the design of the splitter and plug leads to The stability is slightly insufficient, and the actual wearing process is still caused by the fact that the cable is torn off.

In this evaluation, I chose the combination of IPC bundles that I usually use. The amps tried the two portable amps of Mori's PX-M1 and TCG's TURBO, but I finally found that the tuning style of TURBO and KC06A is not very good. In the future, it was dark and boring, so the IPC+PX-M1 bundled solution was chosen. The advantage of this combination is that it is more reductive and has less sound, so it can maximize the sound characteristics of the KC06A itself.

The positioning of KC06A is mainly based on initial burning, the impedance is only 16 ohms, and the sensitivity is 102dB. It is said that the unit consists of the third generation CCAW double cavity and special patented diaphragm, which is easy to push while exerting the hardware advantage in the largest range. Even if you push directly on the NANO4 or 5S, there is no pressure. But the individual still prefers the sense of hearing under greater thrust. Portable amps like the PX-M1 can dig deeper into their potential.

Tri-band:

If you want to use a word to describe the characteristics of K306A, then it must be "equilibrium"! Not only does the tri-band have no obvious shortcomings, but it is also difficult to hear the difference in level. KC06A's low-frequency dive is deep, but not enough. The amount can be supported and a little less cohesive, the atmosphere is not strong; the mid-frequency is slightly more prominent, emphasizing the vocals, but the degree of highlighting is really small. The high-frequency control is good, but also up, unfortunately not transparent and lacking stamina.

Sound field:

The sound field of the KC06A is relatively wide, and the positions on both sides are relatively open. However, the depth of the longitudinal sound field is a little shallower, and the sound density in the space is slightly thinner, so although there is a certain sense of envelopment, it is not particularly sufficient.

Analysis:

Analytic calculation of one of the advantages of the bloody siege, because the K306A's own tuning is still more emphasis on the vocal part, so the vocal processing is still delicate, the details are also outstanding.

Transient, resolution and resolution:

In fact, when I first heard it, I once felt that the K306A was a dynamic, transiently reflecting plug. It rebounded quickly and even gave a strong and powerful feeling. It completely conformed to the "violent preemption of your ears" on the packaging. The declaration! However, with the continuous extension of the downtime, this fierce strength has been greatly reduced, and it has become a moderate balance. Some people may like this "rational return", but I think it is a certain degree of regret. In terms of resolution, the degree of discrimination between vocals and instrumental music can be clearly distinguished, and the vocals are obviously more prominent. The KC06A outlines a picture drawn by a watercolor pen, with color. It is also fresh and pleasant, but after all, it is not rich enough, and the picture is not too strong.

Tuning direction:

The overall impression of KC06A is quite intimate, approachable, the sound line is neither rough nor slender, relatively centered, the tone is slightly warmer, and the vocals are prominent. In the interpretation of stringed instruments such as big violins and guitars and cymbals. When playing music, such as cymbals, flutes, etc., there are good performances, but percussion instruments such as drums, cymbals, cymbals, and keyboard instruments such as pianos are lacking in strength, lack of depth, and a sense of emptiness. It is still popular with vocals that best fits the KC06A's positioning, but it is not omnivorous, because the taste is still a bit weaker when it comes to music types like Jazz and New Century.

It has also been mentioned that KC06A comes with three different types of silicone sleeves, including large-diameter sleeves, small-diameter sleeves and filter sleeves. From the actual audition situation, the difference between the three different sleeves is obvious. A general introduction:

Balanced set:

That is, the small-diameter silicone sleeve, the official description is "enhanced low frequency, improve the hearing resistance, weaken most of the tooth sounds and sounds more gentle and heavy", in fact, the above part of the listening sharing is basically based on the feeling of "balanced set", but From the actual experience, although the balance set is "balanced" and peaceful as its name advertises, in fact, the low frequency is small and it is difficult to make a deep impression. The tooth sound is well controlled, but it is not heavy, but the sound density is slightly thin. A little.

Transparent cover:

Large-diameter silicone sleeve, officially described as "enhanced high-frequency, improve analysis and penetration, more natural and natural", to be honest, these different models of the most suitable for my taste is "transparent sleeve", but I The experience is rather enhanced by the low frequency of the transparent set, especially the amount can be a lot, and the vertical sound field is strengthened, the sense of music is more obvious, but the sound does not become "transparent nature", but tends to be "mellow" full".

Tuning set:

That is, the filter cover, after changing the filter cover, you can feel the sound stimulation of KC06A is strengthened, and the horizontal sound field is further expanded, but there are also some shortcomings, such as the vocal position is farther, the tooth sound is aggravated, and the high frequency sounds more Virtual.

To tell the truth, after listening to more than half a month, writing this review is not an easy task. I have heard a lot of headphones before. The advantages and disadvantages are often an ear, even if the first impression is not completely objective, but I have generally heard After a period of time, I can summarize its characteristics more comprehensively. But this time the KC06A gives me the feeling that it is really difficult to pick up the obvious shortcomings, but to tell the truth, it is difficult to find a deep impression, except for balance or balance. From many burning Friends' feedback, the reputation of the besieged city has been good, but the individual still hopes that in the future, the besieged city will have more distinct personality characteristics in the future, and make better products that are more targeted and more suitable for market segmentation. !
