With the comprehensive upgrade of smartphones, a model that only relies on traditional configurations such as screens and cameras can no longer meet the needs of consumers. Listening to the sounds of nature and using mobile phones instead of HIFI players has become a new trend. The trend has led to the emergence of Hi-Fi mobile phones, which have become the new favorite in the mobile phone market in the past two years. Someone has made statistics. An elite white-collar worker spends 750 hours on conference calls every year. If the sound quality of your mobile phone is poor, then conference calls will be a torture for you. For high-end business elites, a full range of high-definition audio-visual experiences such as clear meeting recordings and conference call sound effects have become new necessities for work and life. When users’ demand for mobile phone sound quality is no longer limited to listening to music, it was launched in 2016 Among mainstream models such as vivo, AXON Tianji 7, and Huawei P9, who is the real audio king? Business mobile phone flagship challenges music mobile phones When it comes to "HI-FI mobile phones", do you still think that this is a mobile phone that focuses on music? The recently launched AXON 7 by ZTE has a very good performance in HiFi. It not only has a built-in professional HiFi chip, but also has professional adjustments in sound quality. It is precisely because of the outstanding performance of ZTE AXON 7 in terms of sound quality that it has begun to arouse the vigilance of other domestic music-focused manufacturers: the sound effects of business mobile phones are challenging the status of music mobile phones. When HiFi was mentioned before, the first thing that everyone thought of should be vivo. Vivo has also launched many products with good sound quality in recent years. However, due to brand positioning, vivo’s users are more young students, and HiFi is only for listening to music. That’s all. As we mentioned earlier, the demand for HiFi among high-end elites is not only for listening to music, but also includes sound quality issues in many aspects such as conference calls and recording playback. Positioned as the business flagship, ZTE AXON 7 can exactly meet the needs of these high-end users. Although ZTE AXON 7 has attracted great attention recently with its powerful camera functions and high configuration such as anti-shake and high pixels, in fact, in terms of sound quality, both ZTE AXON 7 and vivo’s latest Xplay5 can be called HiFi phones. Hi -Fi is the abbreviation of High-Fidelity, literally translated as "high fidelity", that is, a playback sound that is highly similar to the original sound. You can see this by comparing ZTE AXON 7 and vivo Xplay5, two mobile phones with the best sound quality in the industry. The following differences emerge: First of all, the chip specifications and hardware used by the two mobile phones are similar. As the first domestic manufacturer to launch HiFi mobile phones, vivo’s new HiFi flagship vivo Xplay5 still follows its consistent standards in terms of sound quality, which is remarkable. The standard version of vivo Xplay5 uses a CS4398+AD8397 decoding and operational amplifier combination, and the flagship version uses a dual DAC ES9028 chip with three OPA1612 operational amplifiers. Although both phones are equipped with dual HIFI chips, compared to vivo Xplay5 which uses two ES9028 chips, ZTE AXON 7 is equipped with two independent audio chips AK4961 + AK4490, which complement each other better in terms of sound effects and can provide better performance than music-focused mobile phones. A better playback experience is very rare in the industry. Of course, many mobile phones focusing on audio have been equipped with AK4961 before, such as several mobile phones launched by OPPO and other manufacturers. This is an advanced audio DSP codec specially created by AKM for smartphones and tablet products. It integrates low noise and low power consumption. The microphone amplifier can realize voice operations, such as noise reduction and echo elimination. It has been used in Sony professional recording pens and has won high praise from users. The AK4490 was previously commonly used in audiophile-grade walkman or desktop computers, and was used in iRiver and AK380 professional HiFi players. It has received good reviews from portable audio enthusiasts. This is the first time it has been used on a mobile phone. ZTE has also provided perfect sound effects for the AXON Tianji 7. Take great pains. In addition to the support of professional audio chips in terms of hardware, HIFi also requires the debugging capabilities of manufacturers. It is reported that ZTE specially hired the Golden Ears team and doctors from the Conservatory of Music to conduct professional adjustments. In addition, AXON Tianji 7 is also equipped with dual speakers + dual Smart Pa to create surround sound, which significantly improves the sound quality of the mobile phone in terms of sound field, resolution, and high and low frequency control. According to media evaluations, if compared with smartphones, if the sound quality performance of the iPhone is taken as a passing standard of 60 points, and VIVO's Xplay series is taken as a passing standard of 80 points, AXON 7 can reach a level of around 70 points in terms of sound quality alone. Higher than all mobile phones without independent audio module. If you just look at the music playback effect, both ZTE AXON 7 and vivo Xplay5 perform very well. Even picky users will be satisfied with the performance of these two mobile phones. However, it is worth mentioning that the VIVO series has always been targeted at the young, entertainment-oriented market, while the ZTE AXON series has been mainly targeted at high-end business people. Therefore, in the market segment of business users, vivo’s overall performance will be relatively weak, and this is precisely the strength of ZTE AXON 7.

In addition, in terms of sound quality, ZTE AXON 7 not only focuses on the sound quality improvement brought by professional audio chips, but also achieves new breakthroughs in audio-visual experience. ZTE AXON 7 uses Dolby Atmos sound effects. When we use mobile phones to watch videos or experience VR, ZTE AXON 7 can bring an immersive experience, which is something that vivo and even other flagship phones cannot achieved. Therefore, focusing on the hardware foundation while further optimizing the software for experience is the advantage of ZTE AXON 7. Redefining high-end mobile phones with sound quality and photography When a business mobile phone shocked music phones in terms of sound effects, the definition of high-end mobile phones on the market also faced readjustment. As domestic mobile phones gradually "go up", users' requirements for the quality of high-end mobile phones are becoming more and more comprehensive, including not only appearance, craftsmanship, materials, screens, etc., high-end people are also picky about the visual and auditory effects of mobile phones. requirements, such as listening to music, recording videos, recording, high-definition conference calls, voice translation, etc., good sound quality has become the touchstone for testing the quality of a high-end mobile phone. Compared with the recent annual high-end models launched by mainstream Chinese manufacturers, Huawei P9 chose to cooperate with Leica and launched a dual-camera camera function. The overall performance in taking pictures is still good. However, the mobile phone did not emphasize sound quality, and its performance in sound effects was unsatisfactory, which was accused of being a hindrance. Some in the industry believe that under the formula of dual strengths in photography and sound effects, ZTE AXON 7's audio and video performance is far behind that of P9. road. For example, compared with HiFi mobile phones that use professional HiFi chips, ordinary smartphones generally use built-in CODEC (codec). According to the official parameters of Huawei P9, P9 uses HiSilicon Hi6402 audio chip, which supports 24bit high-fidelity audio files. However, this audio chip is only a CODEC, not a professional HiFi chip. In addition, P9 data shows that it integrates HIFI3, and HIFI3 is not HIFI, but an IP core launched by Tensilica. Therefore, although the P9 is equipped with dual front stereo speakers and claims to support HiFi sound effects, the actual sound effects are still far behind those of HiFi phones. Some media released an evaluation report and stated bluntly that "the sound quality of the P9 has reached what we consider to be a passing grade." Nowadays, the positioning of business flagship mobile phones is no longer limited to such limitations as office convenience, safe use, etc., but requires mobile phones to achieve high quality in many aspects such as office work, entertainment, photography, etc. Business mobile phones have a comprehensive quality The requirements are higher. It can be said that making a flagship mobile phone is very simple, but making a business flagship mobile phone requires more energy. When users’ requirements for high-end mobile phones no longer remain at the level of CPU, materials, and craftsmanship, features such as sound quality and photography that can solve users’ pain points have become new standards for high-end mobile phones. From this point of view, compared with vivo Xplay5 and Huawei P9, AXON Tianji 7’s dual strengths of “sound quality + photography” have inherent technical advantages in winning the favor of users. Obviously, for the new business crowd, the balance between work and life, and the integration of soul and experience are the pain points and innovation foundation under the homogenization of flagship mobile phones, whether it is HIFI or photography.
