At the end of 2015, that is, a month ago, HIFIMAN, a well-known domestic HIFI brand "Leader Technology", launched a portable lossless DSD player (national brick) with a model of HM802S, priced at 5999 yuan (with balanced ear amplifier card) / 4399 yuan (with power ear amplifier card 2nd generation).
The price of HM802S still follows the luxury of HIFIMAN's history, not to mention the traditional HIFI player market, whether it can be strongly competitive. If the competition is misplaced, pull it into the high-end mobile phone market, pinyin quality, this price... It is estimated that there is also pressure, after all, many brand models have begun to pay attention to sound quality performance. From the similar price of the iPhone6s to the recent hot quasi-HIFI-level backgammon VIVO X6Plus (about 3,000 yuan), many models may let the HM802S get bogged down.
Too many people want to solve everything with a thinner and lighter mobile phone. Even if it is slightly flawed. Therefore, after the traditional portable HIFI player is manufactured, it is not only the peers who want to PK, but also the operation experience and sound quality performance to beat the mobile phones. The form can be described as quite grim.
Then again, this is the third product with the model name "802". They are the HM802 in 2013, the HM802U in 2015 and the latest model, the HM802S, which was evaluated in this review.
In addition, this is the third HIFIMAN product that I have come into contact with. In order, the HM700 ultra-portable Walkman priced at 500 yuan, the HM901S flagship and this HM802S. Among them, the HM700 made me feel the unique timbre processing of HIFIMAN, which performed better on the vocal lip type and charm. But rough listening will feel a lot like the ordinary MP3 of N years ago. And HM901S, perhaps because of the engineering machine, my good feelings for it can not be talked about at all, the sound is unstable, the overall feeling is too hard, too rushed, the forum often mentioned soft, sweet, I did not feel at all. Just when I doubted my hearing, I found that in the forum, those who listened to the HM901S and HM802 at the same time also had more good feelings for the HM802 as I did. I wonder if this really means that the 802 is relatively more pleasing to the ear?
The HM802U and HM802S are only a few months apart. The main changes are as follows
It can be seen that the most obvious thing about the HM802S compared to the HM802U is the improvement of sound quality (amplification of the sound field), and the boot speed becomes faster. In addition, it is reported that the design of the top of the shell also seems to be a little different.
Regarding "booting", there are more detailed instructions in the manual, which I think is a performance of immature design. Standby, power on, shut down, shut down completely. Four words swirled around in my head, which may seem professional, but it's a bit tedious for everyday use. Not minimalistic. Not directly. It takes a certain amount of time to adapt.
In addition, the 3-second boot speed is not exciting. Because Sony's high-end player boots up fairly quickly. Not to mention that the HM802S has to be pushed 3 seconds after the boot button, and then about 10 seconds later, the operation interface will appear.
The power consumption speed of 7 or 8 hours under standby may make users care more about the importance of "complete shutdown" (power saving), so HIFIMAN also needs to improve the startup speed and standby time. Enhance your daily use experience.
The box is noticeably high-end. Sight, texture, feel are not said. New Year's gifts are absolutely appropriate.
When opened, there is a transparent plastic paper covering, which is a special connection cable designed together with instruction manual, player, power cord, data cable, line output (red, white) and digital coaxial design.
The accessories have a high-level feverish smell just by looking at it. It's a bit of a feeling when I saw a BlackBerry accessory.
The color is standard gray. Depending on the light, there will be changes in depth or shallowness. The overall look is still relatively good-looking. Of course, I also believe that many mobile phone enthusiasts will think that this thing is ugly.
The color is somewhat close to the base of the FlyO X7.
The picture above is a stepper potentiometer (volume knob with a total of 8 cells, 3 levels of volume per cell), which seems to be a major feature of HIFIMAN products, according to the official website is more pure than the traditional digital volume potentiometer sound quality. This must have been a conclusion made after a lot of testing. In addition, this potentiometer is optimized for high-sensitivity earbuds in the low volume area, which can avoid some situations where the volume is more abrupt. Make sure your hearing is smooth. It is very meticulous design, admiration.
The disadvantage is that it is not possible to reduce the volume to a level of "particularly" small. The reason why I say this is because many people like to listen to songs in bed before going to bed, especially in the early morning, when they gradually fall asleep, they will turn the volume of the player to "infinite low". Anyway, mobile phones can't do this. Players with dense digital volume compartments such as the FlyO X7 and COWON PLENUE 1 can. There are also some players where the original minimum volume is very low. And HM802S minimum volume, I tested in the early morning, the feeling is still too clear, affecting sleep, music as a companion at this time should be soft, small, I am not too done. In short, if you can, it is recommended to make a little quieter. The Fei'ao X7 can achieve a very small volume, which is lower than the sound of mosquitoes half a meter away.
For HIMIMMAN, what I appreciate is that they pay a lot of attention to music. In particular, some of its flat headphones seem to have a soft luster, which is indeed toxic. But the player, I listened to the three inside, the current HM802S is good, the other two are not good.

The picture above shows the HM802S power ear amplifier card 2 generation after cutting out the battery, and it is said that the HM801 is the 1st generation of power ear amplifier card. The official webpage says that it can serve most of the more difficult headphones. And the calorific value is lower than before. When the author actually uses it, he does feel that the heat control is good, and it is close to the Fei'ao X7. However, in terms of thermal control, I think the FIIO X7 is still better.
The indicator of the power 2 generation ear amplifier card is shown in the figure. There is a certain gap compared to the balance card. But not extremely picky words, enough is enough.
Battery part. Well, I don't see the meaning of these number symbols. But the official statement that this high-voltage battery pack is also an important part of the performance optimization.
It sounds silly and sometimes sounds silly. I am often confused as to which sound is the most real and moving. There is indeed the knowledge of collocation, the knowledge of audio files, and all kinds of listening psychology at work, so HIFI is a metaphysics. It is difficult for people to clearly explain a truth, an event.
The main objects of contrast in sound quality and styling are the FIIO X7 and SONY D100. Roughly speaking, these three sound base qualities are indeed close. There is no case where anyone can crush whom completely. (Off-topic, Fei'ao's design already has the feeling of a foreign brand.) HIFIMAN is a more retro point feeling. Sony Voice Recorder has mistakenly broken into hifi circles. ）
In addition to the FIIO X7 being slightly thinner, the D100 and HM802S are both thicker and thicker, and the thickness is also very close. It is roughly twice the thickness of the X7.
HM802S and Sony D100 voice recorder
side. X7 is more advanced feeling. It also looks cold (it sounds a bit cold). The HM802S also looks and sounds a bit like it, thick, full and warm. The 802S is side with three parts under this introduction, namely the topmost hold, and the bottom boot (press the push-up mode) and the bottom hole (reset key)
The X7's operation is somewhat self-defeating, it has similar buttons on both sides, which is easy to confuse. And the fingers and palms press on one side on time, and the other side will be accidentally touched by force, which is not too humane. To put it bluntly, in terms of industrial design, domestic products are still a little far from European, American and Japanese products such as Sony. Although foreign products are not necessarily a perfect handling experience, the "error rate" is particularly low. This is the part that domestic manufacturers should pay more attention to improving at present.
The sound of the HM802S has been compared and reassuring for several hours (with earbuds mainly based on Dienko DUNU TITAN5), the completion of the plug is quite high!). Indeed, there is a feeling of "softness" and "softness" (this is the first time I feel it on a HIFIMAN player), and in one of my 32GB SD cards, I have lossless WAV files for the Vienna New Year's Concert, Zhang Xinzhe's DSD files, and various mp3 formats and FLAC formats of scattered songs. Simple comparison of hard qualities, such as dynamics, analysis, sound field, these three aspects compared to the Sony D100 voice recorder seems to have no gap, the feeling is equal, but in the high-frequency performance of different ways, such as when the instrument is played in unison, the pan-high frequency part of the D100 is more regular, there is a sense of distance, a sense of hall, but the musical taste is indeed not so good. The HM802S also shows this kind of music, which will be particularly flavorful, and it is the kind of thing that is wrapped in a transparent oil and impacted. The ear nerve will naturally enjoy the original sharp high-frequency sound. It's a pleasure. In terms of soundstage, the sony D100 monitors the accurate sense of solemnity, which is revealed from time to time, whether the HM802S performs human voices or large orchestral symphonies, it will have a more musical sense of flow, and the burrs are erased a lot. It's a great balance of force and sharpness. Dynamic undulations can also be very strong. That's a good thing for the more exciting soundtracks of the movies.
Compared to X7. The HM802S also has advantages. Both musicality and quality, quite exquisite between the real and the sense of beauty, away from the traditional most of the middle-grade national brick common neutrality, flat. With a more advanced way of presenting music, the X7 is analytically difficult to hear the difference between the two. But in terms of high-frequency expression, the more feminine HM802S is indeed more attractive, which is also reflected in some popular songs, the vocal aspect of the 802S is really easier for me to listen to than the X7, I can do it before going to bed in the early morning can also enjoy. X7 is not suitable for listening at night, in short, the bottom of X7 is still hard. The problem that Fei Ao has not completely solved is here. Some regrets. In the analysis, the hard quality of the sound field can do a good job in the domestic HIFI environment, the musicality, especially the softness of the intermediate and high frequencies, seems to be a problem at present? Although Fei'ao's machines are a little warmer than the next, they are not completely finished. X7 has the gameplay and sound quality of the Android system and HIFI attributes, but unfortunately it still lacks a little taste in the timbre, so it is more difficult to match the earbuds/headphones.
And HM802S, in the four or five earbuds/headphones (about 1,000 yuan) that I have matched in the past few days, can present an overly stimulating, neutral and warm sound, which can be listened to for a long time. This is not only better than the Flyo X7, but also more comfortable than HIFIMAN's top model, the HM901S.
Finally, let's talk about collocation. The Vion X7 is suitable for pairing with earbuds/headphones with thicker low frequencies and non-prominent mid- and high-frequency frequencies, such as the Dienko T5. The T5 is also suitable for the D100, which can alleviate the cold and hard rigidity of the front-end player, presenting delicate analysis and excellent musicality. It is not recommended to use medium and high frequency is very clear, such as the iron triangle CKR9, unless you turn the volume down low.
HM802S, I think this thing can be said to be not picky back-end. It was also the first time I praised the sound quality of HIFIMAN's player. But when it comes to the rebirth of sound quality, I think it is better to use a PC-FI solution. The computer + more than a thousand desktop decoders + ear amplifiers are significantly better than almost all portable lossless players, including the D100. The deep power of large headphones and small earbuds can be fully released. The experience was unbeatable – and that's it.
