Now the sound quality of smart phones is developing very fast, and even has the momentum of catching up with low-end players. This is not only a good thing for users who like to listen to music on their mobile phones, but also high quality mobile phones provide a more portable music for fans who are pursuing portability appreciate Platform, this article will make a simple inventory of the mobile phones that have been released with good audio quality.
vivo X5 Max
As the year-end grand finale of vivo smart phone, the X5 Max can be said to be aggressive. In addition to the amazing ultra-thin body, the newly added Hi Fi 2.0 of vivo has also attracted the attention of players including music enthusiasts. Compared with the traditional audio scheme, The Hi Fi 2.0 audio scheme used on vivo X5 Max includes three professional audio chips: an ES9018K2M DAC from ESS, the SABRE ES9601 first level operational amplifier from ESS, and the prestigious OPA1612 produced by TI. As for the Yamaha YSS205X chip used for karaoke real-time mixing ear return, it is a bit inconspicuous in front of the luxury lineup composed of the previous three chips.
In addition to using professional chips, vivo also optimized the internal power supply design of the X5 Max. After using the new design, the X5 Max can provide 120dB signal-to-noise ratio, 118dB dynamic range, and distortion below - 100dB.
In the actual audition, vivo, through the development of several generations of products, has been able to adjust the voice of the X5 Max to be exquisite and peaceful. The sound field is broad, and the abundant thrust can drive some earphones that ordinary mobile phones cannot drive. It also has the analytical power and amazing quality that surpass all mobile phones, and even has exceeded many professional players of the thousand yuan level on the market, This is really rare for a mobile phone.
Meizu MX4 Pro
Meizu first started as a music player. Before the launch of mobile phones, Meizu's M6 player had a good reputation. However, after Meizu entered the mobile phone industry, it made few achievements in the field of mobile audio. Until the second half of 2014, we saw the proof of Meizu's return to music: MX4 Pro。
Since we are determined to improve the sound quality of mobile phones, we must have special chips, The MX4 Pro uses the ES9018K2M as the DAC, with the OPA1612 operational amplifier, and adds Meizu's marginal filtering technology. As for the power of the amplifier, the MX4 Pro provides high/low gain for users to choose from within the system. If you do not want to manually adjust, it even has an automatic gain selection function. Meizu calls this entire solution Retina Sound.
In terms of specific sound, the sound quality of the MX4 Pro has reached a new height for Meizu mobile phones. The automatic gain selection function makes the driving force of the MX4 Pro quite strong (for a mobile phone), providing very appealing sound and meticulous details.
vivo Xplay 3S
Wait a minute. The Xplay 3S was released in December 2013. How could it appear in the 2014 mobile phone inventory? After all, it was at the end of February 2014 that the Xplay 3S really began to ship in large quantities. To be honest, the strength of the Xplay 3S should not be ignored.
The Xplay 3S is the mobile phone with the largest screen that Vivo has launched so far. It uses a 6-inch 2K screen. In terms of audio, Vivo has inserted an ES9018K2M and OPA2604 into the Xplay 3S, providing 112dB signal-to-noise ratio and distortion below 95dB.
The overall sound trend of the Xplay 3S is similar to that of the X5 Max, which has its own clear style of vivo. The sound is soft and durable. Before the release of the X5 Max, The audio of Xplay 3S has the largest number of favorable comments under vivo, which is inseparable from the impressive analytical power and tri frequency quality of Xplay 3S. However, with the release of X5 Max and vivo's subsequent products, the glory of Xplay 3S will be hidden by the latecomers, but its classic degree will not be diluted by time.
vivo X5
After its release, the X5 was crowned as the King of Hi Fi K Songs by vivo, which is not unreasonable, because in addition to using the combination of CS4398CN (specially customized version of CS4398)+MAX97220 power amplifier to ensure the quality of music playback, the X5 also uses the YSS205X chip of classic Yamaha to achieve the real-time audio mixing ear return capability of K Songs.
In terms of the actual sense of hearing, the X5 has a rather sharp analytical power and high-frequency extensibility, and the low-frequency diving is also very excellent, but the X5's voice is a bit too sharp, so although it has the quality of approaching the Xplay 3S, the overall hearing endurance is not as good as the Xplay 3S, and the subsequent X5 Max is even more out of reach.
vivo X1/X1S/X3
Since these three mobile phones have been available for a long time, let's put them together. As the pioneer of vivo Hi Fi mobile phones, X1 is undoubtedly important, X1 first used CS4398, a high-quality audio decoding chip, on mobile phones, which also made X1 the best phone with the best sound quality at the time of release. This halo even covered the world's thinnest 6.55mm body at that time. Later released X1S improved other aspects of mobile phones while maintaining excellent audio quality, and slightly modified the tuning, This makes the tuning of X1S more in line with the public taste.
As for the X3, it has once again set a new record for the thickness of the ultra-thin mobile phone, with the thinnest body reaching 5.75mm, and replaced the DAC chip with an ES9018K2M with better performance, which is also an attempt by vivo to pursue the sound quality of mobile phones.
HTC ONE（M8/E8）
Among the mobile phones using Qualcomm's own DAC chip, HTC is the most attentive to the sound quality. Both dynamic range and bottom noise control are better than other mobile phones using Qualcomm's DAC. In terms of specific listening sense, HTC ONE has good low-frequency diving and high-frequency extension, and there is no obvious interference between left and right channels on many smart phones, The power of the PO port is also good. Considering that there is no high-quality DAC chip and amplifier chip, it is not easy to have this quality and sense of hearing. In addition, the BoomSound dual speakers equipped by HTC for M8 and E8 also provide the best external amplification effect in the mobile phone industry.
However, no matter how hard HTC is designed and adjusted, the quality and ability of the WCD9320 will limit the music playing effect of HTC mobile phones. I hope HTC can replace this DAC sometime.
Samsung Galaxy Note 4 (Exynos)
See here, first don't complain. Samsung's Galaxy series high-end mobile phones often have two branches that use Exynos processors and Qualcomm processors. Since the Galaxy S4, the use of Qualcomm processors has become the absolute mainstream. The rest of the Exynos processor models are only listed in some regions because the baseband support for the network is not as complete as Qualcomm.
Qualcomm's Snapdragon is called a chipset because it provides a complete set of GPU、 As for mobile solutions including audio, the Exynos processor requires Samsung to equip it with a separate baseband and audio chip. Samsung usually uses Yamaha or Wolfson's DAC. Although they are not as famous as ES9018K2M and CS4398, they are at least better than the WCD9320 provided by Gaotong, Therefore, Samsung mobile phones that often use Exynos processors perform better in terms of sound quality than the same machines that use Snapdragon chipsets.
As for the Galaxy Note 4, Samsung used the combination of Wolfson's WM5110E+Maxim's MAX98504 amplifier this time, which has good sound quality and good analytical power. However, Samsung obviously does not regard sound quality as the main selling point of Galaxy Note 4, Nor did they pay special attention to tuning (after all, most Note 4, including the Bank of China, will use Qualcomm's Snapdragon 805 chipset, but its sound quality...), so even the Exynos processor version of Note 4 does not tune carefully enough, the sound is a bit harsh, and the thrust is also small, which can only drive earphones that are easier to drive, It has no chance to drive earphones with high quality.
However, Samsung has also started to make efforts to improve its own baseband. At present, the Exynos processor version of the Galaxy Note 4 on the Hong Kong market has better support for LTE networks. It is hoped that in the future, Samsung will return to the domestic market with the Exynos processor, and make improvements in audio, so that the flagship mobile phone can live up to its name.
Apple iPhone 5S
Don't ask me why it is 5S instead of 6, because I won't tell you that the sound quality of iPhone 6 and 6 Plus is not as good as that of iPhone 5S. It's true that Apple, which changes the world every year, will fall back.
As one of the best-selling smart phones at present, iPhone has always stood in front of the sound quality of mobile phones before Vivo launched mobile phones using professional Hi Fi chips, surpassing many mainstream Android phones. Apple has never announced the decoder chip used by iPhone 5S, but after hearing about it, The iPhone 5S is really good. Although the thrust is relatively weak and the sound of plain boiled water lacks musical sense, the overall quality is good, which is much stronger than the loose sound of the iPhone 6 and 6 Plus.
Hammer T1
This mobile phone, which they regard as the second best to use in the world, is also very strange in terms of audio. Many manufacturers first replace Qualcomm's barely usable DAC and then consider the issue of operational amplifier, while the hammer is directly loaded with an OPA2604 operational amplifier. This idea is like spreading scrambled eggs over an overnight meal and then mixing them with food - certainly better than eating Qualcomm's overnight meal alone, Bullying and bullying Qualcomm's Samsung/Sony/Xiaomi mobile phones is certainly not stressful. If you want to challenge vivo and MX4 Pro, you'd better go to bed.
As for the actual quality, thanks to the OPA2604, the sound quality of the hammer is OK, a little better than those mobile phones that have never publicized how good their sound quality is. The overall sound has a good performance in detail, while others are not good. Considering the use of such a high level of operational amplifier chips, it is only expected that the hammer can achieve this level, As for reaching the high level that Lao Luo said, we need to use our own brains.
Nubia Z7
Nubia Z7 is a mobile phone with an independent audio decoding chip, but the popularity of the decoding chip it uses is much smaller than CS4398 and ES9018K2M. It is an AK4961 from AKM. According to the introduction of AKM, the total harmonic noise+distortion of this chip is - 99dB, and the dynamic range is 110dB. It is specially designed for smart phones Tablets and portable players provide high fidelity audio playback.
From the data point of view, AK4961 is not cheaper than CS4398 and ES9018K2M, and there is no detailed information about the amplifier used in Z7, so it will not be discussed here.
As for the actual sense of hearing, Thanks to the independent decoding chip, Z7's sound quality is really good. The overall tuning is also very popular. There is nothing special or impressive about it, but it has not made any mistakes. The sound quality is higher than that of HTC ONE and Samsung's Galaxy Note 4. The thrust performance is average. As for the official Hi Fi sound quality, I think it's a bit overstated. If compared with a hammer, the quality of the two is the same, but the tuning of the hammer may be more mature and has some characteristics, and the thrust is slightly larger.
Summary:
For mobile phones, progress in any aspect and to any extent is positive. Mobile phone music has also changed from "listening to music" to "listening to music" now. Fans who once could not see the effect of mobile phone music playing are willing to calm down and experience the progress of mobile phone music. However, due to the size limitation of mobile phones, if you want to completely defeat professional players, At least it is impossible at present. High quality mobile phones are more important to popularize the pursuit of sound quality, so that more people can enjoy better sound quality at less cost. From this point of view, high quality mobile phones are very meaningful.
