X7 is vivo's latest release of the flagship camera, so you can see the X7 in the shooting function and experience more useful and substantive gameplay, and according to the positioning of the previous mobile phone manufacturers, the phone seems to have a focus, whether it shows X7 Has there been some backwardness in music playback?
1: appearance and hardware
Appearance and operation
Vivo X7 overall appearance than the Xplay series change is still relatively large, the front of the home button to the physical buttons and integrated fingerprint recognition module, with a positive coverage of the 2.5D glass screen, whether it is positive or negative on the back give a kind More refined feeling, and when used as a player, the general mobile phone will be placed on the table, the front unlock can save you from picking up the phone to unlock the flaw, it is worthy of praise.
On the back of the vivo X7 is a one-piece metal fuselage, the antenna at the nano-injection processing, the overall clean and simple.
Vivo X7 from left to right in order for the speakers, micro USB port, the main mic and 3.5mm headphone jack, the whole are on a horizontal line, Virgo baby can also enjoy the play.
The way to turn on the Hi-Fi module is the same as before. It is turned on in Settings-Sound-Hi-Fi. Commonly used third-party apps have been adapted so that they can be used with confidence.
The playback interface is still based on simple style. Users can click on the Hi-Fi button to open or close the Hi-Fi module. Click the cover to view the lyrics, and click on the upper right corner to enter the play list.
Classification of tracks is different from most mobile phone built-in apps. vivo X7 pays more attention to the classification and management of local audio sources, and places online resources in the lower right corner. From here, it can be seen that X7 still does not lose the pedigree of music phones.
Audio core architecture
Vivo X7 adopts a new and special custom AK4376 Hi-Fi solution. The biggest difference from the previous vivo music phones is that the AK4376 integrates DACs and amplifiers. The overall area is smaller, and the wiring layout can be better designed, and it is greatly reduced. Power consumption, from the point of view of music phones, this is undoubtedly a tailor-made solution. From the architecture point of view than the CS4398+AD45257 used in the past to more practical and easy to use.
2: Listening and summing up
In the audiometry test, we used the black and yellow skulls and NF4 headphones as references, and the contrasting phones were vivo X6S Plus and Xplay5 standard editions.
Overall performance: Although the AK4376 integrated solution adopted by the X7 depends on the hardware, the CS4398+AD45257 independent solution used by the X6S Plus and the Xplay5 standard version does not matter. However, the X7 output power is basically the same as the other two through trial listening. Quite a bit, the overall performance is not unanimous. Actually with the earplugs, the volume can be driven to 50% -60% can be a good drive, remarkable control.
The X7's voice style can be said to have a very big change compared to its X6S Plus and Xplay5 standard editions. The sound is no longer overly pursuing low-frequency pleasure, but it tends to be softer, but the mid-high-frequency ductility is still a little worse, and it cannot be fully stretched. , But it does not hide, X7 this time the listening style is undoubtedly successful, because if the X6S Plus and Xplay5 standard version without a good ear plugs, it is easy to control the bad low-frequency and cause a head, and X7 this time while tuning It has changed, but it is more resistant to hearing. The analytics are richer than the other two, and the tri-band control is even more balanced.
In the high-frequency performance: X7's high-frequency performance can be said to be relatively non-aggressive, a lot of clean and detailed voice, compared X6S Plus and Xplay5 Standard Edition, in the sense of space is stronger, it sounds more transparent. In terms of listening to human voices, the X7 is more dynamic than the X6S Plus and Xplay5 Standard Editions. In terms of overall hearing, the performance of the X7 can be said to be a music phone that is difficult to listen to, but is very resistant to noise. They are all controlled in a very good position. No one will be more eye-catching. Maybe this is what some big gods say about the so-called desalination.
Low-frequency performance: If the user is vivo, he may not be accustomed to listening to the X7 at first, and the low frequency will appear light and less sense. This is not to say that the driving force of the X7 is not enough, but this time the X7's tuning is like this, or that it is better to control the low frequency. When the black and yellow enamel ring iron earplugs are used, the low frequency can be said to have quality and quantity. , Thickness is good, but send and receive more in place, point to the end, and X6S Plus and Xplay5 Standard Edition will sometimes give more and more income.
Summary: The performance of vivo X7 can be said to surprise Xiaobian, because most Hi-Fi phones are tuned to win, most of them will highlight some aspects of the tri-band to achieve a good sense of hearing, but This time, X7's listening flow brought a fresh taste to Xiao Bian, less extra tone, but it got more details and charms. This also shows that vivo is really a set in the audio field for the first time. The use of the AK4376 solution will be able to perform this way, but if you can highlight a little more in terms of vocal performance, you will always have a feeling of not being able to listen to female voices. For the X6S Plus and Xplay5 Standard Editions Although Xiao Bian can't say who is better than them, I personally prefer the X7. After all, I can still find such a clean voice in my mobile phone, which may be more suitable for listening.
