X7 is the latest photography flagship released by vivo, so it can be seen that X7 has many useful and substantial playing methods in the shooting function and experience. According to the previous positioning of mobile phone manufacturers, mobile phones seem to have a focus. Does that mean that X7 has regressed in music playing?

1: Appearance and hardware

Appearance and operation

The overall appearance of the vivo X7 is quite different from that of the Xplay series. The front has changed the home key to a physical key and integrated a fingerprint identification module. The 2.5D glass screen covered by the front gives a more refined aesthetic feeling, both front and back. When used as a player, the phone is usually placed on the table, Front unlocking can save the embarrassment of picking up the phone to unlock, which is worth praising.

The back of the vivo X7 is an integrated metal body, and the antenna is treated with nano injection molding, which is simple and clean.

From left to right, the vivo X7 is composed of speakers, micro usb ports, main mic and 3.5mm headphone jacks, all of which are on the same horizontal line. Virgo babies can also play happily.

The way to turn on the Hi Fi module is the same as in the past. The commonly used third-party apps have been adapted and can be used with confidence.

The playback interface is still simple. The user can open or close the Hi Fi module by clicking the Hi Fi key. Click the cover to view the lyrics, and click the upper right corner to enter the playlist.

Different from most mobile phone built-in apps, vivo X7 pays more attention to the classification management of local audio sources, while placing online resources in the lower right corner. It can also be seen from this that X7 still does not lose its pedigree as a music phone.

Audio core architecture

The vivo X7 uses a new, specially customized AK4376 Hi Fi solution. The biggest difference from previous vivo music phones is that the AK4376 is integrated with DAC and amplifier. The overall area is smaller, which enables better design of wiring and greatly reduces power consumption. From the perspective of music phones, this is undoubtedly a customized solution. From the perspective of architecture, it is more practical and easy to use than CS4398+AD45257.

2: Hearing sense and summary

In the listening sense test, we used Blackbird and NF4 earphones as a reference, and the phones in comparison were vivo's X6S Plus and Xplay5 standard versions.

Overall performance, The control force is commendable.

Compared with the X6S Plus and the Xplay5 standard version, the sound style of the X7 has changed a lot. The sound is no longer too keen on the pleasure of low frequency. It has begun to be softer. However, the medium and high frequency ductility is still a little poor, and it cannot be fully extended, but the flaws do not cover the flaws. The monitoring style of the X7 is undoubtedly successful, For example, if the X6S Plus and Xplay5 standard versions are not matched with earplugs, it is easy to control the low frequency and cause a blockbuster. This time, the X7 is more durable, although the tuning has changed, the analysis is more abundant than the other two, and the tri frequency control is more balanced.

Medium and high frequency performance: The medium and high frequency performance of the X7 can be said to be less aggressive. Its sound is much cleaner and more detailed. Compared with the X6S Plus and the Xplay5 standard version, it has a stronger sense of space and sounds more transparent. In terms of human voice, the X7 is more dynamic than the X6S Plus and Xplay5 standard version. In terms of the overall sense of hearing, the X7 can be said to be a music phone that is hard to make people drunk, but it is very durable. The middle and high frequencies are controlled in a very good position, and no one will be more eye-catching. Maybe this is what some gods call a fever reducing smell.

Low frequency performance: If you are a vivo user, you may not be used to listening to X7 at the beginning. Low frequency performance will appear light and less quantitative. This is not to say that the driving force of the X7 is insufficient, but that the tuning of the X7 is like this, or that the control of the low frequency is better. When matching with the black oriole and other ring iron earplugs, the low frequency can be said to have quality and quantity, and the thickness is good, but the sending and receiving are more in place. At the end of the day, the X6S Plus and Xplay5 standard versions are often too many to receive back.

Conclusion: The voice performance of the vivo X7 can be said to be a surprise to the small editor, because most Hi Fi phones win by tuning, and most of them will highlight some aspect of the tri band to get a good sense of hearing. But this time, the monitoring stream of the X7 has brought a fresh taste to the small editor, which has gained more details and charm without extra sound pollution, This also shows that vivo really has a set of skills in the audio field. It is really good to use the AK4376 scheme for the first time, but it would be better if it could be a little more prominent in the voice aspect. When listening to female voices, there has always been a feeling of not going up. Compared with the X6S Plus and the Xplay5 standard version, although I can't say which one is better, I personally prefer X7, After all, you can still find such clean and spotless voice in your mobile phone, which may be more suitable for listening to.
