preface

This is a complex era and a beautiful era. In this era, all the manufacturers you can think of and can't think of are making mobile phones. In your perception, they may be website makers, video makers, computer makers, player makers, air conditioners... In short, they are all making mobile phones, Similarly, mobile phone manufacturers and various traditional acoustic manufacturers that you can think of and can't imagine are making earphones, smart, colorful, monitoring, sports, Bluetooth, bone conduction...... Please forgive me for my memory, because there are so many of them. Throughout the whole earphone market, there are a wide range of products from dozens of yuan of street sales to tens of thousands of yuan, with all kinds of gimmicks and "hifi" The hype of has successfully turned consumers into people who eat melons without knowing the truth. Which earphone is the product that fits their ears?

The author's consistent philosophy is that any product is worth getting started only if it can do the most basic functions well, and the most important thing is the excellent sound quality performance of earphones. This is also the reason why the author brought Ostrael KC08. Thank you Love to play computer games Products provided.

Unpacking

The outermost simple environment-friendly carton serves as a basic protective layer to prevent damage to the overall package during transportation.

Many audiophiles of Ostray are familiar with it. KC06 - Besieged City and KC06A - Bloody Besieged City is praised as the dark horse of domestic earphones by many audiophiles. The KC08 brought by the author today is the upgraded product of KC06. After five years of research and development, design - overthrow - redesign - overthrow, and so on, we finally see today's products, such as phoenix nirvana and rebirth. There is a separate "Nirvana" sticker on the sealing film of the outer package - there is a change called rebirth, which is not the so-called feelings but a real mental journey.

KC08's exterior packaging inherits the family style of the Fortress Besieged series - the low-key and introverted black is the main color, and the window opening in the middle makes it clear to the user at a glance. The difference is that the diamond shaped window opening has become square, and the side pull opening has become the side pull opening method. The packaging material is also more robust, the design is more simple, and the texture is better.

The unpacked outer package is more like a whole.

The back is marked with various parameters of kc08, which shows the feelings of an electroacoustic person by honoring the Chinese electroacoustic person.

Open the storage box, earphones, and earplugs from left to right, while the lower layer contains a pair of three pack certificates and earplugs. It can be seen that the accessories of KC08 are not rich, which is a pity compared with earphones. However, each accessory is exquisite. From the gold film with earplugs, we can see the manufacturer's intentions for details.

The flying saucer shaped storage box has a loud name - Panshi. The shell is made of rubber material, which has a good hand feel and is just the right size to hold in one hand; Panshi adopts magnetic suction design, with three powerful magnets on the front and back sides for absorption, which is very convenient to open and close. The internal winding bracket can effectively protect the headset from external force damage. The author likes this beautiful, ingenious and practical design very much. Compared with the storage bag of the besieged city, it has been upgraded several grades in an instant.

As the author has always liked the flat head "streaking", the ear plugs have not been used before. In order to give a comprehensive experience, let's make an exception. After use, we found that there was a hole in the original. The specific differences will be explained in detail later. It should be noted that the metal sheet is thin and sharp, and care should be taken to avoid cuts when handling it.

Details

It is rare for the earphone industry to have a major change in appearance, because most manufacturers use OEM. In order to reduce costs, almost without exception, they use male models, so there is little difference in the products you see. Aositrui is an exception. It has built its own production line and opened the mold separately. Praise for this good work. For beauty, different people have different opinions. The sharp appearance does not conform to the tone of the author, but we have to admit that the appearance design of KC08 is more in line with the public aesthetic.

The titanium alloy cavity with wire drawing process is perfectly fitted with black engineering plastic, and OSTRY LOGO is printed on the side of the cavity. It can be said that every process detail of the cavity is classic. In order to make the sound quality more transparent, there are three sound outlets at the bottom and top of the cavity, and the sound insulation effect of the flat head itself is poor, so the author still does not recommend wearing it when sleeping so as not to affect the pillow person.

The design of the handle part is a bit too much. The wire passes through the hollow titanium plated metal handle, which is very sharp and has a strong sense of design. In order to achieve the effect of high force, the handle does not use the irregular hollow design, which requires six blades of the five axis engraving machine to work for nearly 20 minutes at the same time, and the yield is not high, It is also very difficult for the wire drawing process to create excellent metal texture on such small objects, so KC08 is not well done. Of course, the force is high and the idea is good, but it did not give the author a sense of shock. The reason is that the luster of titanium metal is relatively low-key, and the overall gloss is gray, which does not give the author a magical glare. What makes the author even more regretful is that the handle is too long, which makes my ears ache when I lie on my side. So it can be concluded that Ostrey has devoted a lot of efforts to KC08, which is a little too much.

The inner ear part is also special. It seems that the linear sound outlet has to be molded separately.

KC08 has no remote control, so what is the fake remote control of the branch line? Answer - aesthetic/anti-counterfeiting. Like the Fortress Besieged series, the separate part is printed with a unique anti-counterfeiting code to identify the authenticity. Of course, this function can also be realized on the self-service tracking platform of Autostar.

The headphone cable is made of two materials. The lower part of the branch cable is made of 24 needle high elastic cotton, which looks similar to the nylon upper hand and is obviously more soft. At the same time, it also has the characteristics of nylon anti knotting and is more durable. The part of the branch cable is rubber, and the cable core is made of 4N oxygen free copper fiber core. The three-stage plug is the only external original part of Ostray, which can be regarded as having the core technology! The plug is still very exquisite. The gold plating layer on the surface is thick.

After the appearance introduction, it's time to see the real skills; Children who are used to the in ear style shoes will look contemptuous and talk about the sound quality of the flat head. It is true that the flat head is not as clean as the in ear style in terms of sound insulation, but the sound level, open sound field and loose wearing experience make the author prefer the flat head. Please don't turn the volume to a high level to exclude the impact of noise on the flat head, This is very hard to hear. When I was young, I loved it so much that now my wife often teases me as deaf. So now I don't dare to play with stoppers. It's just a funny box.

To get to the point, it is cruel to let a low-frequency controller play flat. Unfortunately, the author happens to be a low-frequency controller. For the author, the low-frequency of KC08 is very excellent, with a sense of quantity and depth, which can bring you more imagination and sense of hierarchy. The reverberation intensity is moderate, the horizontal sound field is very wide, and the vertical sound field is also passable, giving a good sense of atmosphere and three-dimensional sense. Of course, the only thing lacking for an extremely low frequency controller is the sense of quantity. The author who is used to hearing the full and thick return journey in pure drum music such as Red Cliff Drum and Drum Poetry still feels that its performance is somewhat dry. Fortunately, the sense of measurement has improved significantly after wearing earplugs, so low-frequency controllers should never run naked.

KC08's performance in the middle and high frequency bands is above the average level. The voice is relatively close to the ear, and the image is clear and above the average, but there is no sense of punch. I thought that KC08's performance in women's voices was more than that in men's voices, but after repeated comparisons, I found that the performance in men's voices made me look at it with new eyes. In particular, the strong sense of vicissitudes made Zhao Peng's songs play vividly, The performance of musical instruments benefits from overtones and perfect horizontal sound field, and the sense of hall arises spontaneously. KC08 musical instruments have high separation and good elasticity. Even when dealing with symphonies, it can bring you an immersive feeling.

overview

KC08 has excellent performance at low frequencies, excellent sound field shaping and very good transient performance. As a flat plug, KC08 actually prefers the middle and lower sides in terms of tuning, so the performance at high frequencies is relatively weak. The low-frequency diving is standard, and there are many overtones, but it is not very tight. If there is a breakthrough in the sound collection, it will be perfect. Therefore, when listening to songs like "Dance of the River", the atmosphere is good, but it is a little poor. In terms of intermediate frequency, the positioning of voice seems to be a little remote, so the details are slightly lost, and KC08 is actually a male voice. The Zhao Peng series makes the author very happy! The high frequency is the weak point of KC08. The malleability is general. The positioning of the instrument is relatively clear, but the sound is not very bright. On the whole, KC08 is already a relatively successful flat plug at the price of 599 yuan, which can be well interpreted in terms of popularity and movement, and is enough for most users.
