Koobee MAX2 Koobee X9 is Koobee's latest 5.5 inch large screen hifi music phone uses the ES9018 audio decoding chip, which is only used on HIFI audio devices. I still have some knowledge about this decoding chip and those who like hifi music. Here's an introduction. It's also because of this chip that I, a player who has been active in the audio sector, have a trial experience, ES9018 is the industry's highest performance 32-bit audio DAC solution, designed for Blu ray players, audio preamplifiers, A/V receivers, and professional applications such as recording systems, mixing controllers, and digital audio workstations ES9018 adopts patented 32-bit Hyperstream DAC architecture and time-domain jitter canceller, which can provide up to 135dB signal to noise ratio (DNR) and - 120dB THD+N, accept PCM data, DSD and SPDIF data input, input sampling frequency up to 200kHz, and power consumption less than 100mW Maybe most people don't understand this professional explanation. To put it more generally, I know that there are two audio devices in the market today ES9018， One is the iBasso DX100 and the other is the hifiman901, both of which are portable hifi devices of thousands of yuan. thus it can be seen Koobee MAX2 takes great pains in audio, but the sound quality depends on the later tuning and component circuit integration.

When the koobee MAX2 was delivered, I could not wait to open the package of the koobee MAX2. Compared with most mobile phones, the package of the koobee MAX2 was almost monster like the words on the package. At first, I thought it was a flat package. Of course, the overall package was like a large gift box, showing a slightly elegant atmosphere. For a rude person like me, no matter how the package is, I think the most important thing is how the phone is inside. I have started to listen to the songs in the phone since I opened the package. In fact, before I tried the koobee MAX2, I didn't think that the phone could produce good sound, because I heard a lot of phone music, including the iPhone 5s, Even 5S can't meet my demand for portable music, The voice of 5S is dry, flat and weak. Although the voice is crisp, it still cannot meet my needs for portable music. Before auditioning the koobee MAX2, I didn't have much hope for the koobee MAX2. I think it is almost enough to reach the 5s sound quality level, but after auditioning, I felt totally different, First of all, the koobee MAX2 does not reach the level of dx100 and hifiman 901, or even the level of the sony m10 and lotoo l300e I have used, but it is no exaggeration to say that its sound quality is absolutely superior to the iPhone 5s. At the same time, I am satisfied with the sound quality performance of the koobee MAX2, which can fully meet my needs for portable music devices. As for the sound quality performance, I will make a detailed analysis in the next practical experience. Please pay attention. This article introduces the appearance and function interface of koobee MAX2.

When it comes to music and audio digital, I can't help but say a lot. I forgot the theme of this trial. I am also the administrator of the ZOL audio enthusiast group. I have never forgotten my hobbies from college until now after work. Friends with the same hobbies can join the group privately and discuss together.

Let's begin this topic: The appearance of koobee MAX2, The koobee MAX2 is generally satisfied when it is used, but there are also some unsatisfactory aspects. The specific advantages and disadvantages will be introduced one by one in this experience.

In appearance The koobee MAX2 gives me a sense of high class. At first, it feels a little like the white 5S of the large version. The whole shell uses the same metal shell as the iPhone 5s, the same edge technology, and the same metal body. Maybe many people are disgusted with the comparison with the iPhone 5s, but The body material and process of koobee MAX2 are very similar to those of the iPhone 5s, which may be a kind of imitation. It is not impossible to imitate the process of the 5s, which is a guarantee of quality.
I don't know how you feel when you open the package of koobee MAX2. My feeling is: 1. The reason why the box is so large is that not only the phone, but also the phone case is included. 2. I feel that the feminine color inside the package is heavy. The color and the case are similar to those designed for women.

The koobee MAX2 is almost the phone with the most accessories I have ever seen. It has not only conventional manual data line chargers, but also the original front and rear film, cartoon sticker, original headset, original protective case and an OTG cable, Koobee MAX2 does not support memory expansion. It should be possible to directly read movies, pictures, music, etc. from a U disk or a mobile hard disk through the otg cable.

The koobee MAX2 protective case has a good handle and a good texture. It is very useful for long-term use, to protect the phone, and to prevent the phone from bumping.

I almost forgot here, because Koobee MAX2 uses the same micro sim card as the iPhone 4s. When installing the sim card, you need to use a pin to press out the sim card slot, Koobee MAX2 also has a special card slot needle on the package of the manual.

The koobee MAX2 is a cuboid as a whole. Due to the adoption of a process similar to 5s, even the front shape is very similar to 5s. The screen adopts the ODS full fitting process, making the screen and the body natural. The front frame is pure white, which is a common shape. Many mobile phones are similar to this shape, because the shape itself is also very beautiful. The upper front is a earpiece, a 500w pixel front camera, a sensor and a hidden indicator light. At the bottom of the mobile phone are three conventional touch keys for Android phones. The three touch keys are outside the screen and do not occupy the area of the screen. Many mobile phones in the market, including Sony, claim to have 5-inch to 6-inch large screen phones, but in fact, the virtual keys occupy a part of the actual use area of the screen that does not reach the claimed screen area. and The koobee MAX2 is really a large 5.5 inch screen with a visible area. At the same time, the very narrow border design makes the phone not too big to hold.

The back design of koobee MAX2 is also very brief. It adopts a very popular three-stage design. The beauty of simplicity will give people a sense of temperament. Excessive decoration will make the phone look out of fashion. A sony stack 1300W pixel and a led fill light make it feel very good when I first got the hand photo, which is the leading level in the mobile phone camera. The specific sample effect will be released later. The middle of the back is simple koobee logo。 The voice cavity on the back is designed as the feature of the machine, which adopts the design of dual YAMAHA power amplifiers+dual speakers. The sound effect is clear and loud, and there is no broken sound when the sound is turned on to the maximum. The stereo music effect can be obviously felt by the dual speakers in a short distance and a small range.

The koobee MAX2 adopts an integrated metal frame design. The edge of the frame is arc cut. The material is also metal. The texture is strong and the hand is cold. The overall thickness is basically the same as that of the iPhone 5s. The card slot can only be opened with a pin. The built-in dual micro sim card slot supports TD-SCDMA and GSM dual card dual standby.

The koobee MAX2 is not a mobile phone with the main configuration. Today, more or less major mobile phone manufacturers are piling up hardware and configuration. Four core and eight core mobile phones are emerging one after another. The mobile phones with low price and high configuration are also repeated. Many mobile phone manufacturers are also launching a variety of phones with excellent performance price ratio under the banner of high performance price ratio, Many people think that buying is equal to making money. In fact, they often only look at the screen parameters of the mobile phone CPU, but many potential values are not found, such as how about the mobile phone workmanship? What kind of technology and materials are used to make mobile phones? How about the quality? How is the photo taken? Is the sound quality good and the screen feel good? What accessories are available? How about the system? In fact, there are many places where the value of a mobile phone is reflected. Then this article focuses on How does koobee MAX2 feel in use, and what are its convenience and inconvenience.

Due to the limitation of the number of words in the appearance appreciation of the previous article, it is impossible to make further research on Koobee MAX2 will introduce it. Here is a little supplement. Of course, I have occupied the third floor of this article in advance. I can rest assured that this article will try to The use experience of koobee MAX2 is shown in more detail. before yes Two interesting accessories of koobee MAX2, one is Dormancy protective sleeve included with koobee MAX2. This protective case has multiple functions. Of course, the first is to protect the phone from falling, shaking and bumping. At the same time, this protective cover can be like a small bracket, which is inclined to place the screen on the desktop, so it is convenient to watch movies and other operations.

The original protective sleeve bracket of koobee MAX2 can adjust the angle, which is very convenient and practical to use.

At the same time, the protective case of koobee MAX2 is also a protective case similar to the iPad sleeping case. When the protective case is closed, the mobile phone will enter into the sleep state. Press the wake-up screen, the time and relevant phone messages will be displayed, but the desktop will not really wake up. You need to open the protective case to wake up the wallpaper desktop, which helps to extend the standby time of the mobile phone. The function is practical, The design is reasonable.

Another interesting accessory of koobee MAX2 is the piggy shaped bracket. The following is the effect of the piggy bracket. It is also beautiful and convenient to use.

Speaking of the features of the koobee MAX2 phone, I think the sound quality of this phone is too good, Koobee MAX2 is a mobile phone that focuses on mobile phone music hifi. It uses professional audio processing chips on the audio, so I think the best choice is the actual audio quality. As a music beginner, I also have several earphones in my hand. I believe that the sound quality of an audio device cannot be determined simply by a earphone, In particular, I think it is unreasonable to use original earphones to appreciate the sound quality of mobile phones. An entry-level earphone costs several hundred yuan, while more high-end earphones often cost several thousand yuan, which is not acceptable for the cost of original earphones. I have always hoped for the concept of music phones, but I am disappointed with the mobile phones I have heard, None of them can achieve the effect I want. So when you go out, you should take an antique hard disk MP3 or a larger recorder. The appearance is not beautiful, and the volume is relatively large, which means that I took two mobile phones with me when I went out. As a music device that I take with me when I go out, I don't think it is necessary to reach a high level. It is not necessary to show all the details of music. In fact, I can't hear too many details in a noisy environment, but I mainly enjoy big dynamic music parts such as voice. Therefore, if we do a better job in the orientation of sound quality and timbre, we can use it as a mobile device instead of high-quality MP3.

How about the sound quality of koobee MAX2? Let's experience and introduce my feelings in detail.

First of all, use the Philips SHL5605GY ear to listen. The middle and high frequency sound and detail positioning of this headset are very good. In particular, this headset has a headset that allows you to talk. The headset has been certified by Apple The koobee MAX2 is also universal. It can make phone calls and listen to music.

At first, The music effect of koobee MAX2 is really good, the voice is neutral, and there is no special highlight, but the overall connection is more natural, and the style is suitable for popularity. Philips SHL5605GY has a good performance in alto, which is Koobee MAX2 didn't show it. The three frequencies are balanced. The sound is relatively transparent. After a simple audition of popular songs, I used the relevant audition songs for audition. Try to listen to "Ferry". In the prelude, the drums are very empty, but the drums don't dive deep, and the sense of position is very good. The most commendable thing is that he has performed well in human voice, which truly restored Cai Qin's voice. Although the clarity of musical instruments is somewhat lacking, the sound quality of mobile phones is really good. Then try to listen to Hotel California. The prelude began to perform well. The only thing that made me feel regretful was that I didn't always feel up to the mark on the bass, the dive was not deep enough, and the vocal performance and on-site performance were commendable. After listening to two songs, I found that The overall sound effect of koobee MAX2 is very good, but the details are slightly lacking, and the vocal performance is good. I haven't made too much comment on the time occupied by the bass, because Philips The SHL5605GY earphone has its own defect in bass. I think we need to use several other earphones to test the performance.

AKG K420 is a headset with very strong bass. Its excellent sound quality and sound dyeing are very popular among players at the entry level. Although I have played with earphones worth hundreds to thousands of yuan and bought and sold many earphones before and after, the 420 has always been in hand, because the sound dyeing effect of this earphone is really suitable for listening outside, and the strong bass is comparable to Gauss pp, And the voice is also very well decorated. After the audition, I have to say that the sound quality of koobee MAX2 has reached a new level thanks to the earphones from Austria. After the audition of Ferry again, I found that the bass performance is good, and the bass performance is just right, not too heavy, but also relatively high quality. The AKG K420 itself is too heavy on the bass, so it can be inferred that the koobee MAX2 is still a little weak on the bass. However, after 420 collocations, the voice is more charming. The details are more obvious.

After auditioning with Sennheiser MAX365 earphones, I found that the performance of earphones was significantly better than that of earphones, and the whole space felt more obvious than that of the previous two earphones. This made me feel a bit strange. Generally, the sound field of large earphones was larger than that of earphones, which showed the opposite trend in koobee MAX2. Listening with earphones, I felt more transparent and clearer, I think koobee may add some modifications to the earphone playing to make the sound quality of earplugs sound better. Especially in the audition of Hotel California, the sense of detail and scene is stronger, and a lot of details can be distinguished in a quiet place. However, during the audition, the disadvantage of koobee MAX2 is also found. When the music is turned on loud, the earphone can hear obvious bottom noise, which has a certain impact on the sense of hearing. Although low noise does not affect the ability to listen to music when traveling, But it will have a greater impact on listening in a quiet environment. My last recording pen, sony m10, was transferred to someone else because of the obvious background noise. I was disappointed to hear it on koobee MAX2. I hope Koobee engineers can find out the cause and reduce the bottom noise. On the whole, the sound quality performance of koobee MAX2 is really very good. Among the mobile phones I have heard, including the iPhone 5s, the performance is the best.

The original earphones are the last ones I auditioned. Readers, I tell you that in the process of auditioning, I was actually writing my feelings while listening with the earphones. I really didn't listen to the original earphones before. In my opinion, the original earphones usually don't do well, and at most they are about 50 yuan worth of sound quality (value division in my heart) But after listening to it now, I found that the performance of this original earplug was beyond my expectation. His performance on koobee MAX2 completely exceeded that of the Sennheiser MX365 I used before. This really surprised me. I can't say how good the quality of this earplug is, but the sound effect of this earplug is completely matched with koobee MAX2. The momentum of the music suddenly comes up, and the bass diving is also in place. The voice is not bright enough, but it sounds good. After listening to the original earplug, I think if you want to upgrade the earplug for koobee MAX2, it is unnecessary to upgrade the earplug below 200 yuan.

Summarize the performance of koobee MAX2 in playing music with headphones, The audio quality of the koobee MAX2 is the best among the mobile phones I've heard of. Of course, there is still a gap between it and professional mobile audio devices. After all, it is only a mobile phone with a price of 1000 yuan, and the better mobile audio devices have a price of 1000 yuan. For users who want better audio quality but do not want to be particularly enthusiastic Koobee MAX2 is a very good choice. Its sound quality is basically higher than that of MP3 within 1000 yuan, but it can't surpass the hifi audio equipment of higher level. To make it convenient for beginners like me who often listen to music during travel Koobee MAX2 will be more convenient than carrying a big brick like device, and Koobee MAX2 can decode lossless formats such as ape flac. This cannot be decoded in many high-end devices.

After listening to the music quality played by the headset, I think it is necessary to introduce The audio quality of koobee MAX2. The audio quality of koobee MAX2 can be said to be very good. The sound is clear and crisp, and the volume is very large, which is larger than most Android and Apple phones. If you want to know the level of his external audio, I think it can be said to be the speaker of the enlarged version of the iPhone 5s. At the same time, it is a dual channel, which will have a very obvious stereo effect when listening in the near field. There is no broken sound when the voice is turned to the maximum, and the workmanship is not rough.

Yes Koobee MAX2, a small Bluetooth speaker, is basically unnecessary, The koobee MAX2's built-in external amplifier is better than ordinary small Bluetooth speakers. However, with the advancement of technology and society, people's quality of life and convenience have been greatly improved. Bluetooth speakers have also appeared on high-end multimedia speakers, such as the Huiwei T200C. As a Bluetooth speaker, it has the high quality of wired multimedia speakers, Then if the mobile phone is connected through Bluetooth, the sound quality of the mobile phone will also affect the sound quality of the Bluetooth speaker, so a mobile phone with good sound quality is very meaningful. After all, I think the mobile phone is the most convenient device for Bluetooth connection.

Some basic applications, such as reading books, are even more important. Thanks to the large high-definition screen of the mobile phone, koobee MAX2 has a very good font display effect in reading. Of course, reading itself is a basic application with good fluency.

In terms of video function, I ordered a 720p Superman movie, which is about 3.6g in size. It can be seen that both the bit rate and the image quality are very high. When using the built-in player, there is no jam and other phenomena, and the drag is smooth. At the same time, the playback effect on the 5.5 inch screen is very good. I haven't tested too many movies. I think it's enough to decode 720p movies. Few people watch movies over 720p on their mobile phones

It is necessary to play games as a leisure entertainment project. In fact, I think it is good to play leisure games on mobile phones. It is really unpleasant to play large 3D games on the touch screen. However, in order to meet the needs of different players, I have tested two large 3D games with high requirements at present, and there is no difficulty in playing them. It seems that koobee MAX2 has become very mainstream in hardware, Although it is not as powerful as Xiaolong 800 and T4, it can handle mainstream large-scale 3rd class games with ease. If the performance is too high, it will also increase the power consumption, which has a certain impact on the battery life of the mobile phone. If it is enough, I don't think it is necessary to pursue a fever configuration. Practicality is king.

Summarize the features of koobee MAX2

Speaking of the features of max2, I think as the newly released flagship of koobee, it has its own characteristics and value compared with ordinary mobile phones.

Feature 1: All metal body. The technology is advanced, the feel and texture are very good.

Feature 2: The third generation of gorilla glass is more wear-resistant, scratch resistant and shock resistant.

Feature 3: 5.5 inch 720p high-definition screen with excellent display effect.

Feature 4: The dido os customized system is smooth and responsive.

Feature 5: The front 500w and rear 1300w pixel cameras have more professional software and hardware settings, and the photo taking effect is very good.

Feature 6: Double Yamaha speakers, very good sound effect

Feature 7: Independent audio decoder chip. The sound effect exceeds that of most mobile phones.

Feature 8: The quality of accessory earphones is very good, exceeding the 100 yuan earphones sold on the market.

The above eight points are the characteristics that I think this mobile phone surpasses most mobile phones on the market, and also the essence of the value of this mobile phone. Of course, I also found the shortcomings of this mobile phone in use. as follows

Shortcomings: The accessories are too feminine, which is awkward for male users.

Second, the use of micro sim cards is not very convenient for many users.

Less than three: The battery cannot be replaced, and the battery life is average.

Less than four: there is no cdma telecommunications in the network system (which makes the majority of telecom users feel embarrassed).
