Vivo Xplay is the successor X1 With the third mobile phone after X1s that focuses on Hi Fi sound quality, Xplay not only continues the chip matching of CS4398 (DAC) and CS8422 (SRC) on X1, but also adds an OPA2604 operational amplifier chip. In addition to the new tuning, what surprises will the sound of Xplay bring us?

At the beginning, the combination of X1's CS4398 and CS8422 has reached the top level of sound quality in the mobile phone. What's special about the addition of an independent operational amplifier chip this time? Let's have a brief look at this op amp chip. OPA2604 is a top A-B operational amplifier, which belongs to BB Company of Texas Instruments. In addition to the powerful parameters of the chip itself, Xplay also has a positive and negative 5.8V boost circuit design, which can improve the final audio output capability and listening sense. The audio quality has been greatly improved, and the signal-to-noise ratio has risen to an astonishing level of 104dB. Among the top operational amplifier chips, OPA2604 is the one with the most stringent requirements for power supply and circuit design. There are few successful examples under low voltage and low impedance. Xplay has overcome this problem and put this "three core" combination on a mobile phone using Qualcomm SoC for the first time.

Listening phone: vivo Xplay

Comparison of mobile phones: iPhone 5, X1St

Headphones: UE10, GR07MK2, VSD1, VC02, XE600, etc

Song file format: FLAC, WAV

First, let's look at the music player of Xplay. The layout of the player is the same as that of X1S and X1. The playback interface supports the opening of Hi Fi mode, SRS and BBE sound effects, and supports the replacement of the player skin ▼

The playlist has some beautification relative to X1 and X1S ▼

As for the interface of sound effect setting, the Hi Fi mode of Xplay is the same as that of X1. After it is turned on, digital audio will be transferred to analog signals through CS4398, and then sound through headphones ▼

SRS sound effect can adjust EQ for songs of different styles ▼

BBE sound effect can fine tune the sound style for specific earphones, which can be understood as some special tuning ▼ for these earphones

In order not to be affected by the special sound dyeing of sound effect Turn off sound effect and turn on Hi Fi mode 。

Hearing summary:

High frequency: because the low frequency performance is too eye-catching, the high frequency of Xplay is relatively not so brilliant. High frequency details are outstanding, and there is no burr. Unfortunately, there are still some deficiencies in the high frequency extension.

Intermediate frequency: Xplay belongs to warm sound equipment. The intermediate frequency is thick and the voice is very emotional. Compared with X1's IF, Xplay has greatly improved the problem of too loud sound and slight burr. Xplay has not surpassed the previous generation of products in terms of IF quality, but has significantly improved its hearing endurance, taking a listening direction.

Low frequency: Low frequency is the most satisfying part of Xplay for Xiaobian. The quality, quantity and surrounding feeling of low frequency are all the best in mobile phones. In the past, low frequency processing methods of products usually increase the amount of low frequency, and add some sound effects that are heavily stained or even degrade the sound quality. The low frequency of Xplay is better than that of ordinary mobile phones. Under the condition of ensuring a certain low frequency measurement, the strength and texture of low frequency have reached a very high level, and the elasticity of low frequency is much better than that of ordinary mobile phones.

Analysis: Xplay has a strong analytical power, sound details are well preserved, strong materials and excellent circuit design make Xplay achieve a high level in analysis.

Sound field: The sound field of Xplay is larger than that of X1St and iPhone5. Its excellent separation makes it especially suitable for playback of some classical music when it is properly matched.

Matching: If you like to listen to popular and rock music, you only need to match some balanced earphones to have a good performance on Xplay. If you choose some earphones with strong low-frequency power, it will appear "heavy taste". If you like to listen to some female voices and classical songs, you can match them with earphones with thin sound background, so that they can complement each other. After joining OPA2604, the push force of the mobile phone itself has indeed increased. However, due to circuit design and power supply problems, the push force of Xplay is still weaker than that of the traditional audiophone, so it is still recommended to use small earphones and portable earplugs with low impedance and high sensitivity.

Overall sound style: The sound of Xplay follows the Hi Fi route. The overall sound trend is a balanced warm sound, which is unique in terms of low-frequency strength and texture. The sound has a certain tone dye, which gives people a unique "simulated taste". What we hear from Xplay is not only the sound quality, but also the outstanding sense of hearing. It is a powerful sound, from fist to flesh.

Compared with the iPhone 5, the sound quality of Xplay is basically better than that of the iPhone 5, and it is more excellent in listening sense. Compared with iPhone 5, Xplay has more powerful voice and more dynamic. Of course, for the relatively bland style of iPhone 5, there will be more choice in matching earphones.

Compared with X1St, the sound quality of Xplay has slightly improved (X1St has replaced the CS4398 of X1 with CS4353), and with the addition of OPA2604, the sound trend has become much easier and softer, so the new release added this time is more about the improvement of hearing endurance of Xplay itself.

Xplay has a unique sound for mobile phones and even portable devices. Its high quality and excellent hearing endurance make it an excellent front end for users. It is not easy for a mobile phone to reach this level of sound quality. Of course, the quality of a mobile phone can't be judged only by its sound quality. In the next evaluation, we will test the comprehensive level of Xplay. In addition, it is believed that many netizens are also interested in the Xplay earphone XE600. However, since the Xplay is not long after its arrival, the XE600 still needs a "burn in" process, so its sound quality will also be mentioned in the detailed evaluation of Xplay.
