HiFi earphones have always been music lovers' dream of listening to music. However, manufacturers of HiFi earphones must have some skills to really do a good job. OSTRY (Chinese name: OSTRY) acoustic brand, founded in 2012, is affiliated to Shenzhen OSTRY Technology Co., Ltd. The company is a high-tech enterprise engaged in the development of Hi Fi (High Fidelity) earphones and earphone drivers, and the integration of acoustic equipment and related fields. It is now integrated with its own brand products, ODM and OEM properties. After the launch of two in ear HiFi earplugs, KC06 and KC06A, the traditional flat head HiFi earplug KC08 was launched this time. This model has a lot of metal elements, and the texture is very good.

Nowadays, Internet enterprises have made great efforts in packaging in order to sell online. In order to avoid accidental packaging during transportation, the outer layer of KC08 is wrapped in kraft paper and printed with the words OSTRY and KC08.

The inner package, which is also the formal package, adopts the now popular transparent middle package, which can directly see the inner earphone, and the black package on both sides. The above column, "Nirvana has a change called rebirth", does it mean that flat head headphones are going to be popular again!?

Such a mature packaging design looks pretty beautiful, at least giving a deep impression at first. The back of the product package is mainly the main parameters of KC08: 16mm drive unit, sensitivity 105dB, impedance 32, power 10mW, etc.

The disassembly of packaging is also quite interesting, which is divided into three stages. The real box is in the middle, and there are two covers on the left and right!! Such an interesting design really needs to be praised by the designer!

There are not many accessories in the package. This flat head earplug is only equipped with two earplugs and a good earphone storage box. However, it is basically enough for flat head earplugs. Sponge earmuffs are still fixed with metal brackets and look very high-end!

This small black box is the earplug storage box, which is printed with cool product logo and OSTRY! And the surface is sanded. It's not just to put earplugs in the box, but to wind the earplug wires in slowly, which is too troublesome for lazy people like me. The opening and closing of the box is also special. Three magnets are used to hold the two sides of the box firmly. It shows that Chinese design is really hard!!

The workmanship of the small earmuffs is also good, and they are fixed on such metal inserts, which looks very high-end!

Let's take a look at the main body of KC08, flat head earplugs. There are many metal elements on the earplug, which looks very mechanical.

The flat head part of the earplug is also equipped with metal pieces, which makes the overall feel of the earplug very good. In addition, the introduction of the flat head plug is really a rebirth when the in ear plug is so popular now!

The other parts of the earplug are also very carefully made, 3.5mm are all gold plated. The earphone is not equipped with a microphone, so a simple treatment will be carried out at the decomposition point. In terms of details, you can see the earphone wire. The earplug part is ordinary glue wire, and the outer layer of the back part is covered with 24 needle high elastic cotton woven wire. The workmanship and feel are very, very good!

Xiao Bian is just a tough loser. He doesn't have a lossless audio player, so he can only use this smartphone instead. The experience of the small editor's actual audition is very good! The tri frequency earplug is relatively average, which can basically restore songs with good sound quality!

Wearing effect, whether directly or around, is no problem. My ears are very normal and comfortable.

It's good to listen to music with earplugs and the music app provided by the mobile phone. Although it can't achieve the so-called lossless sound quality effect, it's very helpful to find many old songs on the Internet!

Many Android phones have such a sound quality optimization function, which can effectively improve the sound field effect. However, the simpler the music is, the better. The former equipment is a CD player, a power amplifier and a pair of speakers! So the editor still thinks that it is true to turn off the sound quality and optimize the original flavor!

First of all, I listened to my favorite rock music. Dou Wei's songs are still so special. There are many musical instruments interwoven with noisy subtle changes, and these complex sounds are very good to experience with KC08. As mentioned above, the tri band balance can not feel how protruding the bass or how harsh the treble is. It's a very peaceful feeling. Of course, it's also a very powerful feeling to experience Zhao Chuan's songs!

Then listen to Jacky Cheung's songs, and the experience of the IF is still clear and bright, without the feeling of turbidity. The detailed sound experience is also suitable for listening to Wubai's songs. There is no more gorgeous movement but a detailed and clear voice. The deep guitar sound is very good! It can be said that although this earplug is small, it can't push KC08 very well with such little guys as mobile phones.

In terms of female voice, I still have to experience Cai Qin's songs. I also feel the delicate female voice. The performance of the mid bass is still remarkable. Cai Qin's magnetic voice is very authentic, clear and euphemistic! Let's listen to Liang Yongqi's Xiaoqingxin. The performance of the treble part is also quite good. The rise is not urgent and very smooth. The sound quality is quite outstanding. The sound of the song is restored to a high standard, and the appearance and performance of the HiFi headset are achieved!

As flat head earplugs, let's compare their appearance with in ear earplugs. Although they are not as eye-catching as in ear earplugs, don't Chinese people just like the golden mean?!

Compared with the rear hanging earphones, the compact KC08 is easy to carry, and its workmanship is excellent, not inferior to that of international brands!

Advantages: exquisite workmanship, excellent sound quality. The three frequencies are relatively average. The middle and high tones can rise without distortion, and the bass can sink without the feeling of "loose" or "stuffy". The overall experience of listening to music is very good, and many details of music can be heard! Great!

Disadvantages: Xiaobian doesn't like to use earmuffs, but there are fewer earmuffs for free. Generally, three pairs of earmuffs should be sent for users to choose and replace. Moreover, I personally feel that the price of a brand earplug 599 that is not well-known in China is a little high, but actually after listening to it, I feel that it is still worth more!

To sum up, this KC08 flat head earplug produced by OSTRY has a good appearance and the use of metal elements, which makes people look bright. The performance of sound quality is much better than the external sense sense. Although the performance of triple frequency is balanced, the bass is not loose, and the treble is clear, simple, and highly reductive, while the performance of mid frequency is also relatively simple and delicate. It can be said that this is a pair of flat head earplugs that are not very luxurious but can bring the listener a luxurious experience. It is recommended that the manufacturer keep the current design style, and the next generation of products can consider the design of headphone or rear hanging earphone, which should be liked by more music lovers (the main type of flat head earplugs can not be suitable for all people to wear, due to the size of the ear hole)! Finally, I would like to recommend this earphone to you, and hope that domestic earphones can be better and better!
