HIFIMAN HM901R has been heatedly discussed by many music enthusiasts once it was launched. After improvement, hm901r can be regarded as the flagship player of HYMALAYA with the self-developed R2R chip of Heifeman. The sound is not only biased towards the black prince, In terms of weight, it is more portable than the black prince. It is hard to imagine that such a lightweight machine can also have the taste of a black prince.
I usually carry a re2000 with me when I go out for portability, but when I’m at home, I prefer to use headphones, because in-ear earphones and headphones cannot be built anyway. In terms of sound field, the headwear of the same price is better than in-ear headphones.
In March last year, I evaluated Hifiman Hifiman DEVA for everyone. DEVA is more like a headset with no obvious shortcomings in balance in all aspects. It supports wired and Bluetooth. What's more, the flat diaphragm of Heifemann's consistent style is also used, which is remarkable in terms of sound details. This year, HIFIMAN has upgraded the DEVA series, adding an invisible magnet structure that is more conducive to the purity of the sound, which is the HIFIMAN DEVA Pro headset you see in the picture above.
Headphones out of the box, the product includes a pair of headphones, a Bluetooth module, a 3.5mm matching headphone cable, a USB charging cable, a product introduction/warranty card.
Hifiman HIFIMAN DEVA Pro this color matching and DEVA is still quite different,It is no longer the warm orange design of DEVA, but the same as the HE400SE invisible magnet version, with a somewhat cold metal taste. There are brand, model, and L/R logos on the outside and inside of the earstalk, and the earstalks are retractable and adopt a circular buckle design.
The part that wraps the ears is still designed with leather + cotton, which is very soft and delicate to the touch, and the speaker grille is faintly visible under the light. Of course, the ear cotton part can be separately applied later replace.
Because I listen to music at home, I usually use wired, lossless transmission, and it is matched with Hifiman HM901R, 18Ω impedance is quite good, and a unit drives the sound. Surging and powerful.
This combination should be said to be a HIFI weapon for many enthusiasts. Whether it is the quality of the hm901r itself or the quality of the DEVA Pro flat diaphragm, the sound is not bad, especially when listening to large-scale music. The various musical instruments are intertwined, but the sound location of each musical instrument can be clearly distinguished, which has a sense of hierarchy.
The most important thing is that HIFIMAN DEVA Pro also added an invisible magnet structure of the same design as Susvara this time. This technology optimizes and improves the air turbulence and reflection between the magnet gaps. It can make the magnet "invisible" in front of the sound wave, and get a more pure and complete sound.
Pro version of the Bluemini Bluetooth module, using R2R architecture, built-in HIFIMAN self-developed Himalayan chip,It is equivalent to connecting a high-quality music player to the headset, and supports multiple high-definition Bluetooth protocols such as LDAC, aptX-HD, aptX, AAC, and SBC.
operation is very simple, long press the power button to switch the machine, double-click for Bluetooth pairing, after a connection, each time you turn on Bluetooth, it will automatically connect, charging and DAC functions can be through Type-C To proceed.
The new Bluemini R2R Bluetooth module, built-in HYMALAYA DAC chip, the signal-to-noise ratio can be comparable to PCM1704, far better than the common PCM63, AD1865 chips used by friends. And the total harmonic distortion of the Himalaya chip is even better than PCM1704.
Thanks to the 20mW ultra-low power consumption of the Himalayan chip, its single-use battery life exceeds 8 hours. It can be said that the Hifiman Hifiman DEVA Pro version is indeed better than the previous DEVA in terms of sound Quality, or battery life, will win a lot. In the sound audition, the channel separation of DEVA Pro increased by 20 decibels, so when listening to "Silk Road" similar to Liang Jingru, the separation between the left and right ears is particularly obvious, even better than re2000, and the sound field On the one hand, the effect of the super large flat diaphragm + NEO super nano diaphragm is better, and after the invisible magnet structure is upgraded, the sound purity of DEVA Pro is cleaner, so that the resolution is also improved a lot, whether it is listening to big programming or popular In music, the sound positioning and imaging of the background instruments are particularly clear, the horizontal sound field and the vertical sound field are staggered, and the three-dimensional effect is better. If you like headphones, you must try the combination of HIFIMAN HM901R and DEVA Pro.Especially DEVA Pro, the price is only 1799 yuan, which can be said to be quite wow.
