For many enthusiasts who have requirements for sound quality, it is of course common to have a variety of HIFI players, various headphones, and ear amplifiers at home, but if you commute daily, some thicker players are not very convenient to carry out, so mobile phones have become one of the devices that many people listen to songs, after all, mobile phones are handy, pants pockets, bags are casually pulled out, and the body can start to swing with music when wearing headphones.
Since it is a mobile phone to listen to songs, and there are only a few mobile phones with built-in HIFI chips, for some users with high sound quality requirements, how can they get one ear amplifier? Then again, wired headphones originally have a headphone cable, and then hang a "small hanging bottle decoder" is really a bit embarrassing, just HIFIMAN recently launched a so-called "ultra-miniature portable ear amplifier", not only small and portable but also built-in "Himalaya" R2R DAC chip, think about it feel a little bit energetic, because it set off a revolution in the field of HIFI.
Net weight 9.65g, real portable decoding ear amplifier
When I first started with the HIFIMAN HM800, I was really amazed. The compact body made of all-aluminum alloy material has ultra-high portability, and the weight is a bit ridiculously light, with a net weight of only 9.65g. Around the fuselage treated by the sandblasting process, the luster of bulging shines in the light, and with the metal drawing process, it can be said that the texture is overflowing in the air, and I believe it will hit the lower heart of many yan value parties.
HIFIMAN HM800 comes with several audio cables, in addition to the C to C data cable for the connection of the mobile phone and the HM800, it also includes MMCX-0.78, MMCX-0.75 pin cable, and a MMCX coaxial cable, adapted to different styles of detachable earbuds, in fact, invisibly HIFIMAN HM800 has become part of the earbuds.
Self-developed Himalayan R2R DAC, a milestone of domestic self-development
In addition to the small body of the whole machine light, HIFIMAN HM800 also built in THE PERFECTMAN independent research and development of THE NORMALAYA (Himalaya) R2R DAC chip, you know, this DAC chip is the first domestic self-developed product, when the global semiconductor market suffered from the "lack of core crisis", the shipments of many manufacturers are constrained by the output of chips, as well as the high premium of rarity, and the emergence of Himalaya R2R DAC chips, It also makes HIMIMAN no longer subject to people.
The significance of the emergence of THE HIFIMAN HM800 is that there is currently no competitor in this field that can match its volume and weight, as an independent Class A and B ear amplifier (non-Class D), compared to the traditional "small tail" using a cheap decoding chip, HYMALAYA R2R DAC chip has lower power consumption, greater thrust, and its advantages We will also experience the hearing below.
It is worth mentioning that the DAC chip on the HIFIMAN HM800 is based on the R2R architecture, which was previously used in Hi-End audio equipment. The Himalaya R2R DAC chip has considerable book parameters, with a signal-to-noise ratio of 112dB and a total harmonic distortion (DAC module) of only 0.0025%, which can fully compete with the level of PCM1704.
Himalaya R2R DAC chip in the control of power consumption is also more outstanding, power consumption is only 20mW, compared to the PCM1704's 450mW is dozens of times lower, and the low power consumption of the dividend is to save power, now the smartphone battery life is still in the stage of competing with the power consumption of the mobile phone flagship chip, if you superimpose a large power consumer, the actual user experience will also be more than worth the loss, HIFIMAN self-developed R2R DAC chip in the audio field can be said to have a high milestone significance.
Subjective auditory experience
Regardless of whether the headphones or the player or the decoder ear amplifier, in order to achieve the right degree of running-in, it is recommended to accelerate the aging and stability of the equipment through the pot machine, we can understand it as the run-in period between the singer and the band, there is no strict specification for the music used in the pot machine, we only need to use the medium volume to continuously play the type of music that they like to listen to every day, pay attention to the continuous playback time should not be too long, every 30 hours to rest 5 to 6 hours, after all, the machine and people, but also pay attention to the "combination of work and leisure".
The author's personal daily listening to songs tends to pop music, after 2 days of pot, indeed on the basis of headphones added HIFIMAN HM800 decoding ear amplifier, the sense of hearing is to rise a ladder, high and low three frequencies have different degrees of improvement.
Yuan Yawei "Dancing on the Moon"
A song composed by Yuan Yawei and Tao Leran, with a lazy after being slightly drunk, Tia's psychedelic tension singing voice makes the song high-end, and the combination of weak voice and wind music further strengthens the hazy atmosphere of the whole song, which is fascinating. Hifiman HM800 on the basis of the original to strengthen the low frequency of the submersible volume, Tia in the weak part of the performance of the ear feeling is also given, the overall has a remarkable hearing resistance, no obvious distortion and over-modification of the situation.
Adele《Set Fire to the Rain》
In the "21" album, this "Set Fire to the Rain" belongs to a very melodic one, Adele's singing ability can be said to be smooth and balanced, whether it is resonance or high-frequency thick wrapping feeling, through the control of virtual reality, strength and weakness, the strong pop and pop soul song is interpreted with flesh and blood. HIFIMAN HM800's performance in this song is also extremely eye-catching, the tooth tone, ventilation, and the presentation of the angry part are a good demonstration of its accurate restoration of the lossless sound source, so that the listener can fully support this song wrapped by the tragic gorgeous string music from the depths of the heart, and the huge sound field and the majestic sense of tragedy are revealed everywhere.
summary
Combined with the above sense of hearing, HIFIMAN HM800 provides an entrance to exclusive hifi music, only less than 2000 prices, for many listeners who pursue sound quality but do not have a hifi player around to provide a set of listening solutions that can be carried out of the street. HYMALAYA R2R DAC chip not only resists the banner of the rise of domestic DAC chips in thrust and power consumption, it can be said that HIFIMAN HM800, which integrates the ear with the earbud body, deserves a tidal wave of applause from every "HIFI MAN" who loves audio.
