I was looking for a Hi-Fi headset that could meet multiple scenes while listening to wired, high-quality music and wireless audio. After a few turns, a chance I met it - continuing the HIFIMAN HE-R series "wooden bowl" shape of the HIFIMAN HE-R9 sealing dynamic ring headphones, retro and elegant burgundy round ear cups, the feeling of the above brings a very strong impact, the interior of the full space, but also gives the R9 the opportunity to be able to have both open and closed big ears at the same time. Coupled with the standard Bluemini R2R module, HIFIMAN HE-R9 completely breaks the barrier between wired and wireless. For such a very distinctive head-on-ear, I believe that everyone is also looking forward to its performance, so let's take a look at it together.
Classic without losing elegance, lightweight without chucking
Although sometimes we say that appearance is not important, how many people can really turn a blind eye? So whether it's headphones or other products, the first step for everyone to recognize it must be the appearance. The appearance of the HIFIMAN HE-R9 continues the classic "wooden bowl" design elements of he-R10, of course, because the positioning of the two products is slightly different, the material and color of the HIFIMAN HE-R9 ear cups have been readjusted. The same "wooden bowl" shape is matched with an extremely elegant burgundy color, hifiman HE-R9 is very easy to impress on the appearance level.
With dual compatibility mode is also one of the reasons why the landlord chooses HIFIMAN HE-R9, the default wiring bilateral 3.5mm wiring, if you want to improve the sound quality or change the listening style, you can connect the left side of the single-ended balance 3.5mm line. In addition to the cable connection, the left jack can also be matched with the included Bluetooth module Bluemini R2R, and the HIFIMAN HE-R9 after the combination is a bluetooth headset with excellent sound quality. HIFIMAN HE-R9 should be considered the most powerful headphones in terms of function, right?
Lightweight is also one of the more obvious features of THE HIFIMAN HE-R9, even with the Bluetooth module, the weight of the HIFIMAN HE-R9 is only 353g, and the lighter weight also solves the problem of indenter neck that is common in headphones.
The hifiman HE-R9 has a full leather design on the outside of the head, and the overall touch is very soft and delicate. The memory foam filled inside, after special measurements, has reached an excellent level of fit and elasticity. The skull frame is a solid steel skeleton that combines weight and strength.
The ear cups part of the wrapping feeling is very good, the memory foam brings a good elasticity at the same time, but also brings better breathability, the actual wear so that the ear has enough space and breathability, long-term wear does not pressure the ear.
Topological diaphragm black technology, taking into account the length of openness and closure
Speaking of the HIFIMAN brand, it is impossible to avoid the world's only topological diaphragm technology, which is also one of the biggest core competitiveness of this brand that distinguishes it from other headphones. In addition, it is HILIMMAN's highly recognizable tuning technology, which also creates HIFIMAN's unique brand image in the audio field.
Hifiman HE-R9, as a closed dynamic headphone launched in 2021, uses a topological diaphragm speaker unit without any suspense. Thanks to the extremely high sensitivity brought by the super rare earth magnet and the high-frequency extension brought by the topological diaphragm, the sensitivity of hifiman HE-R9 has reached 100dB, and the frequency response range has reached 15Hz-35Hz.
In terms of other technical features, thanks to the strong equivalent volume and sufficient breathing space brought by the filling space of the "wooden bowl" (ear cup) structure, hifiman HE-R9 solves the problem of small sound field and turbid atmosphere of traditional closed headphones. The actual sound of the HIFIMAN HE-R9 is both the excellent bass and thicker vocals brought by the enclosed headphone surround, as well as the relaxed atmosphere of the open headphones and the more natural sound performance.
The tuning is full of charm, and the sound is rounded and full without losing detail
For closed headphones at this price point, I believe that the official positioning of the product should be the main cable connection, after all, for HiFi enthusiasts, wired means quality, but also means that you can try to match more different front ends according to personal preferences. The Bluetooth module of Bluemini R2R, which uses Himalaya's self-developed DAC chip, can bring better convenience. HIFIMAN's head-mounted ears in the past two years have fully considered the needs of all aspects, that is, there is wired quality and unlimited DIY possibilities, and there is wireless convenience, which should be a very successful attempt in the field of headphones in the past two years.
Using the data cable included in the package and the powerful Foobar2000 lossless music player on the computer side, with a desktop amplifier or a player with USB DAC function, coupled with the PURCHASE OFFIMAN HE-R9 closed dynamic earbuds, we can quickly build a set of lossless music system with very reliable sound quality and particularly convenient use.
This time as a stage is the Shanling M3X lossless music player, the power of this player under high gain is 240mW@32 Ω, and the power of single-ended dual DAC is 101mW@32 Ω (other hardware and parameters you can Baidu). The following will share with you the personal listening experience of the HIFIMAN HE-R9.
First of all, let's talk about the feeling of the first smell of HIFIMAN HE-R9, the first ear of the feeling is very comfortable, this comfort is mainly reflected in two aspects, on the one hand, the comfort of wearing, the completely negligible chuck feeling, the extremely light weight is not pressed, and the touch of the fabric in contact with the skin is also very delicate. On the other hand, the sound of comfort, HIFIMAN HE-R9's overall tone is warm, the sound is round and full, the vocals are particularly pleasing, coupled with excellent analytical ability, basically a variety of genres can be pinched by the right benefits.
The moment you put on the HIMIMMAN HE-R9, when the melody of the piano master Ludovico Einaudi's "Experience" begins to sound, the quiet rhythm at the beginning can immediately calm people's minds, and the immersion brought by the closed headphones is vividly expressed at this moment. The tiny crackling beans between the quiet sounds of each key fully demonstrate the superb analytical power of THE HIFIMAN HE-R9, including the climax of the back, when the piano, violin, and cello are sounded, the layering of the sound is still very distinct.
When using the HIFIMAN HE-R9 to listen to the relatively brisk European and American pop songs of Justin Bieber's "Stay", the headphones' low-frequency transient response is excellent, and the diving and elasticity are just right, without giving people a feeling of procrastination. HIFIMAN HE-R9 in the vocal tuning is also the most respected by individuals, in listening to some Chinese pop songs, such as Tian Fuzhen "No one knows", Sun Yanzi "Peace", Eason Chan "Song Ode", you can clearly feel that this headset is very smart in the handling of the human voice, that is, there is a sense of closeness to the ear that makes people feel in the comfort area, and there is a suitable atmosphere to set off, especially the middle and high frequency details of the female voice, rich and full, bright and not thorny, which fully reflects the advantages of the topological diaphragm unit in the middle and high frequencies.
Write at the end
During this time, hifiman HE-R9 has shown extremely high quality, both in wired mode and with the included Bluemini R2R module. Especially in wired mode, HIFIMAN HE-R9 is very easy to push, but also let us do not need more advanced front-end to play the strength of HIFIMAN HE-R9. For example, with the combination of this Mountain Spirit M3X player, there is a kind of extremely comfortable charm, the sound is round and full without losing detail, and the overall slightly warm sound tuning is particularly pleasant to listen to in this cold winter.
In general, if you have requirements for the appearance of headphones, the pursuit of the sound of headphones, and hope that headphones can adapt to more use scenarios, HIFIMAN HE-R9 should be one of the best choices.
