IT168 Special article The huge market potential of digital products has attracted more and more manufacturers to enter this field. In this spring season, domestic Daheng Technology released their new MP3 player that enters the digital field. appliance products, including a full range of products in three grades: high, middle and low. The author had the opportunity to get its high-end product; ZINO z700i was used for evaluation.
As a pioneer in the field of digital products, the high-end product ZINO z700i launched by Daheng does have unique performance.
As soon as I got this product, I felt its temptation. The pure black outer packaging box has a mysterious power, showing elegance and solemnity. And the packaging is very simple. Unlike some products that decorate the packaging box in an extremely fancy way to attract users, the packaging of ZINO z700i has no other text except the ZINO brand logo on the front and the Daheng information on the back.
When you open the packaging box, you will find the main character white inside, which symbolizes pride and purity, as if you have escaped from the secular society and are in a "paradise". The two extremely simple colors of black and white outline a sharp contrast and foil.
In addition to the protagonist ZINO z700i, the random accessories include white headphones, transparent product jacket, shiny lanyard, USB cable, audio recording cable, warranty card, manual and software driver CD. The accessories are quite complete.

The shape of the z700i is a rectangular parallelepiped, which is relatively thick. Its front and back are different colors and materials. The front half of the front uses a double-layer anti-wear design. The inner layer is made of milky white plastic material, and the outer layer is plated with a layer of hard transparent plastic. The LCD area in the middle is also surrounded. In this way, You don’t have to worry about the LCD screen being scratched. The second half of the back is made of an alloy-like material, using bright silver electroplating paint, which makes it look shiny. The workmanship of the Z700i is very fine, the joints between the front and rear parts are very tight, and there is a screw on the back of the entire fuselage.

The front LCD screen and two buttons are concentrated on the right In the side area, the left side is the ZINO brand logo. The LCD screen of the z700i is also very well made. It is different from the blue backlight of other MP3 player products, but uses a white backlight. The lighting is even, there are no obvious dark corners, the fonts are clear and delicate, and it can display enough Information, and supports lyrics display, the visual effect looks great. Its menu not only has Chinese prompts, but also has a graphical interface, which is very intuitive and clear.

However, unfortunately, during use, the author found The song titles displayed during playback of some songs will be garbled, which should not be the case. I believe it can be corrected and improved through firmware upgrades. Below the LCD screen are the power on/play/pause/off buttons and the recording button. There is a corresponding English word description on the left side of each button, and the description text of the recording button is still orange. On the right side of the recording button, there is a small indicator light. When recording, it emits a red light to remind the user of the current working status.
#$[*154559.jpg*#a*#0*#0*#center*]$#
On the upper side of the fuselage, there are audio recording jacks, A-B Repeat/FM transmit button and volume adjustment button. The audio recording function is also a must-have function for mainstream high-end products. Friends may be surprised by the FM transmit button. Yes, I was also very confused when I first came into contact with this function. However, the author will introduce this function in detail in the function section, so I won’t go into details here. The audio recording jack has a milky white plastic protective cover to protect it from dust contamination.
#$[*154564.jpg*#a*#0*#0*#center*]$#
The lower side of the z700i fuselage is a three-way button, which can be Menu operation, fast forward and rewind functions. On the upper right side of the three-way button is the built-in microphone. The control of the three-way key is very flexible.
#$[*154566.jpg*#a*#0*#0*#center*]$#
Let’s look at the right side of the fuselage, where the external headphone plug is hole, mode selection and key lock integrated keys. There is also a lanyard hole. Z700i combines the mode selection and key lock functions with a sliding button. Compared with many other products that use menu operation mode selection, it is indeed more convenient. However, during use, the author found that it is easy to slide the selected position when locking the button. Moreover, after the button is used for a long time, the definitions between each position will not be clear, making it easier to misoperate. .
#$[*154580.jpg*#a*#0*#0*#center*]$#
The left side of the fuselage is a standard retractable USB interface. There is also a milky white plastic protective cover on the interface. In addition, you can also see the words Made In Korea.
#$[*154581.jpg*#a*#0*#0*#center*]$#
The buttons for telescopic operation are on the back of the fuselage. Below this telescopic push-pull button is the battery compartment. The difference is that the z700i is powered by a standard AA battery instead of the most common AA battery, which undoubtedly greatly increases the battery life. You can also see the word D’Cube on the back, which is the brand logo of the z700i prototype. However, the bright silver paint on the back is very shiny and easily attracts fingerprints.
#$[*154582.jpg*#a*#0*#0*#center*]$#
After understanding the appearance of z700i, I believe many friends will I have a deep impression on it. Yes, I think the manufacturer is indeed unique in the product's appearance design and color selection. There is no obvious difference in the positioning of men and women. I believe that both boys and girls will be more suitable for this product. However, for girls, hanging it around their necks still seems a little "heavy".
In addition to the appearance, the function is also a highlight of the z700i, especially the FM transmitting function that the author has mentioned above, so at the beginning of the function introduction, the author will first tell you about the FM transmitter. Function.
I believe everyone should be familiar with the working principle of radio stations. Take our radio as an example. The Central People's Broadcasting Station uses radio technology to transmit signals of various frequencies. We can use ordinary radios to Such wireless signals are received to receive radio programs of different frequencies. Just like this working principle, z700i has the function of transmitting wireless signals. It can transmit MP3 songs or sounds played on the machine at the frequency set by the user. If you use other radios, you can receive them at the corresponding transmission frequency. The wireless signal it emits is used to listen to its playback sound. Other radios can be those on our commonly used Walkmans, independent radios, or car radios. Of course, the distance between the transmitter and the receiver cannot be too far. I tested that when the straight-line distance between them was controlled at about 3 meters, the reception effect was excellent and the listening was very clear. When the player is in the FM wireless transmitting state, the indicator light next to the recording button introduced above displays red. It is precisely because such products can be used in cars that some people call them car MP3 players.
This is indeed a good supplement to the car CD player. When some songs, especially some more professional content, cannot be played on a CD player, this MP3 player product comes in handy. However, one thing to note is that when manually setting the frequency of transmission, you cannot occupy the frequency that has been used by FM FM. For example, you cannot transmit at FM97.4KHz frequency, otherwise it will affect the listening of normal frequencies.
In addition to the unique wireless transmitting function, z700i also has all other functions, including MP3 playback, FM radio, voice and audio recording, which makes it a high-end product.
The menu of z700i not only has Chinese display, but also graphical display, making the operation clear at a glance. The menu setting items are very detailed. For example, in the sound effect menu, it is divided into four categories: bass search, 3D sound effect, EQ sound effect and custom sound effect. Custom sound effects can be selected in five options: bass, mid1, mid2, mid3, and treb. Each has a plus or minus six levels of adjustment space, the 3D sound comparison also has a 15-level adjustment range, and the bass search also provides a plus or minus 5-level adjustment range. For those who love to play, you can fully unleash its potential and provide you with better music.
In addition, z700i can also set the playback speed, sleep timer, standby timer, battery type used, subtitle scrolling speed, startup and shutdown screen, menu language and many other settings.
In short, the menu settings are very rich and powerful. Here, the author wants to focus on its standby function, which is similar to the standby mode of a computer. When the player is in standby mode, it shuts down the machine to save power. When the player is turned on again, it will remember the last time it was in standby. state, and automatically start playing from that state. This brings a lot of convenience to users in actual use.
The playback sound quality of z700i can be regarded as the best among the MP3 player products that the author has come into contact with. The author listened to the "Forgotten Time" that I like very much. The z700i's low frequency is warm and rich, the dive is very solid, and the string timbre is very charming, without unnecessary impurities, but smooth, transparent, delicate and exquisite. Although the tone is a bit dark, the subjective listening experience is extremely comfortable. Its sound field is far away, which is very close to the actual effect of enjoying the performance in the auditorium of the concert hall. The texture and volume are sufficient, and the bass performance is very good.
Then, the author listened to rock music with relatively high sound quality. I felt that the treble part was still a bit dry, but treble is also a long-standing "pain point" of MP3 players.
However, when I was using it, I did not find the file deletion function, and I did not find any relevant instructions in the manual. This is what I regret.
The FM radio listening effect of z700i is also very good. Among all the MP3 players I have used, its radio listening quality should be ranked among the best. Similarly, it also supports manual and automatic search, and the supported frequency range is from 87.5MHz to 108MHz. Again I won’t say much more.
Let’s take a look at the recording effect of z700i. The recording function is now a must-have function on MP3 player products (voice recording), and the audio recording function is also very common on mid-to-high-end products. According to the author’s experience and feelings in using MP3 players, the gap between various products in terms of recording is getting smaller and smaller, and since recording is not a professional function, many friends do not attach great importance to the recording function, as long as it can meet the basic requirements That's it.
Z700i's recording provides a variety of recording sound quality options: 32Kbps, 40 Kbps, 48 ??Kbps, 56 Kbps, 64 Kbps, 80 Kbps, 96 Kbps, 112 Kbps, 128 Kbps, 160 Kbps, 192 Kbps, 224 Kbps*** 12 options. As the author said above, the menu options are very detailed. The author conducted recording tests under the 96Kbps and 128Kbps options. Facts have proved that the recording effects under these two options are not very different. The sound playback is very clear and the restoration is relatively good. It can be said that there is no problem in meeting the requirements of most users. Of course, the same goes for audio recording. ?
Since z700i uses a standard USB interface, it can be used as a mobile USB flash drive. The author used professional software to test its transmission speed. As shown in the figure below, you can see its transmission speed. The speed is not very high, only over 500K.

Summary:
As a Daheng company The pioneer of high-end products in the digital field, the performance of z700i is undoubtedly satisfactory. Both the appearance design and functional application of the fuselage show that it is unique, especially its wireless frequency transmitting function, which is currently It is rare among MP3 player products. I believe this product will win the favor of many white-collar workers and fashionable young people.
