    Bass Goodness: RE800
    Written by tassardar
    Published Sep 1, 2017
    Pros - Fantastic Bass, Good Soundstage, Small and Light, Good Sibilance Control
    Cons - Fixed Cable, A Little Hollow Sounding at times, Not much treble energy
    The RE800 is the second Hifiman IEM review I'm writing after the RE2000. Thanks to AVOne and Hifiman for the review sample.

    image1 (1).JPG

    The RE800 is probably the smallest dynamic driver earphone I seen. Fully sealed and in gold, this little thing bears some similarity to others of its type but also a significant difference.

    I wont touch so much on what came with the packaging here where many reviewers covered. Personally I thought its just about right for a earphone of its type: Some tips, a carrying case and a box that holds both of this. I do find the box space alittle wasted since you cant put much else. Other that that, for its price, I find it acceptable.


    What I couldn't find acceptable was the fixed cables. The first thing that breaks in most earphones was the cable going wrong. Hifiman in its pursue for miniaturisation probably taught it was a good idea to leave removable cables out and this was definitely not what most people would had wanted unless its something like electrostatic. Add on with the thinness of the cables, my dealers did say they will do their best if anything happens...

    Other then cables, the build is decent: All metal at around 1cm + long. Put on a double flange tip, its light and will sink in deep into your ear. Due to it being relatively small and light, it did not need a hook over ear. This is self is quite a pro since small means easy to mange, keep and wear. It would also mean have less fit problems for most.

    So how does it sound?


    Albums used:
    Aimer Day Dream
    Final Fantasy 14 Soundtrack
    Beauty and the Beast

    Player: ZX2
    Compared to : KSE1500, RE2000

    Coming after the RE2000, I was prepared to lower my expectation since this was meant to be the little brother. But after hearing it, I personally thought the quality of sound difference isn't great except 2 major things: Vocals and Warmth.

    Lets start with the warmth, the RE800 do not bear much similarity to most IEM using Dynamic Drivers from my memory when it comes to warmth. Be it the Lyra or the RE2000, the RE800 sounded a little cool, at times it even felt a little hollow. It didn't have the mass and warmth I expect from a dynamic driver. However this is a preference and luckily due my preference to KSE1500, I quite enjoy this lighter, cooler touch of sound from the RE800. So a direct switch from RE2000 to the RE800, this is definitely its biggest and most apparent difference.

    Then it follows the vocals, the RE2000 isolates the vocals and brings it forward, quite a surreal experience if your enjoy vocals. The RE800 treatment of vocals were a little different. It sounds separated but distant, at the edge of the music together with the instruments. It also sounded a little hollow and metallic at times due to the lack of warmth and mass. Its also just not as smooth as RE2000 liquid like or KSE1500's quick and light. I am probably exaggerating here since the difference were small and you probably will only notice it if you been hearing something like the Re2000 for extensive period of time.

    After the comparison above lets talk about whats great: The Bass.
    Personally, I may actually enjoy this more then the RE2000. It has just enough of everything: Impact, Depth and most importantly "Feel". KSE1500 sounds like bass is there, RE2000 has the impact and warmth, but the RE800 had the impact when needed together with the tiny feeling of bass vibration. Fantastic really. This was noticeable with FF14 Sound Track - Dragonsong, I can surely say, I will listen that sound using this earphone over the RE2000 and KSE1500.

    The other good characters is something it shares with RE2000, which is the sibilance characters. Short of the worst of tracks, its relatively tamed, making it a great choice of modern pop music. Plus it being less warmth, it definitely fits into modern genres a lot better then the RE2000.

    Soundstage is wide, wider then what i remember for most earphones of its class. Its probably just a touch smaller the RE2000, definitely good enough for its class. Similarly for details, its good but just a little lower then RE2000 and KSE1500. This is noticeable in complicated instrument tracks from FF14 Soundtrack. Some softer instruments will get lost in the track, not a huge issue though and if you are a loud listener, it probably wont be as much of a issue.

    What I think it lacks was treble energy. Treble was there, just not much excitement, energy or speed compared to BAs and KSE1500 electrostatic. This made it less musical for tracks that are bass light and treble heavy. However when the opposite happens, I think this was not an issue in my listening experience. An example was listening to Skyfall, which really did not contain much of the higher frequencies, and through the RE800, it sounded fantastic.


    All this said, I thought the RE800 is a rather good IEM for its class, except the lack of removable cable and not much accessories, its definitely something that people can consider for its sound quality. If I had to recommend it to someone, it will be to people who listen to modern pop music due to its good sibilance and bass character.

    Pros - Beautifully built, Open, detailed, dynamic sound, Transparency, impressive resolution, Crystal clear trebles, amazing comfort and fit, Detachable cable,
    Cons - Trebles can be too much for some, not for bass-heads.
    Before start this review, I would like to share technical aspects and package details.



    Frequency Response : 5Hz-20kHz

    Impedance : 60Ω

    Sensitivity : 105dB

    Earphone Weight : 0.95oz (27g)

    Driver: 9.2mm dynamic driver

    Housing: brass 24k electroplated gold.


    - RE800 Earphone

    - Detachable MMCX cable

    - 3 Pair silicon Tips – 1 pair Comply Foam

    - Aluminium Case


    Design & Isolation;

    The RE800 has high quality 24K gold-plated brass body. The junction points are clean and there are no flaws or faults on the body. It feels very good in the hand. It is extremely successful in terms of ergonomics and fit. The model I owe is the current version which can be plugged into the MMCX. It's not loose when the cable is plugged in. Its very durable and solid. The cable can be inserted into the current MMCX version unlike the previous model, so you can upgrade your cable. Visually, RE800 looks like jewellery in your hand and much more beautiful than its pictures.

    The RE800 has a tiny little body and it is almost disappearing when you wear. Fit feels incredibly comfortable. Although the RE800 itself is a little bit heavy, you don’t feel any discomfort or imbalance in the ear. It is also quite comfortable with silicone and Comply tips. The stock cable that comes with RE800 also looks good. The material is soft and nice to touch. When you put the RE800 into the storage case, there is no tangling. I don’t have any MMCX cable, so I haven’t been able to experienced it sound with another type of cables. I think the right cable choice would be a copper or copper hybrid cable.

    In conclusion, I liked the RE800 in terms of design, materials and workmanship.


    Sound Type:

    The RE800 has crystal-clear presentation and amazingly high resolution at top frequencies. The level of resolution is unbelievably high. Especially, I would like to point out the resolution; I don't think it is possible to buy any earphones with higher resolution in this price range. Immaculate vocals, clear timbres and nice strong bass are the best words to describe the RE800. Particularly the details and the speed of the trebles are really top notch. This may not be suitable for everyone, but the RE800 has a quality that can impress you even if you do not like trebles. Middle frequencies are a bit behind in the general spectrum but not too far behind. However, when you listen with warm sources, the bass is satisfying. Soundstage is wide as open-headphones. The overall sound character is transparent and bright.



    The RE800 is one of the most detailed dynamic earphone I have ever listened and I think treble is the most special frequency area of the RE800. The amount of the treble is much more prominent than the other frequencies and these tops add clarity to the earphones. When playing music, it gives the feeling of every sound coming from different place into the soundstage. It is quite detailed and fast. It reflects all the errors and details in your ear clearly. The upper frequencies have extremely high resolution, fretless and distinctive. I can easily say that I haven’t heard any universal earphone that have better treble. The RE800 reflects every mistake of the records. If the record is clear, you cannot hear any sibilance, but if the record is bad, the sibilance is quite obvious to hear. The RE800 has its own unique tune that I have never heard before.

    The treble is generally bright / shiny, but in spite of it character, it doesn’t show any unnatural presentation. Dr.Fang did a very fine tuning of the treble. If you use it with bright sources, it may be a little tiring and that’s why I recommend to use it with warmer sources. The general presentation of treble may be excessive for some users, but if you are a treble lover, this is the right earphone for you.

    I would like to mention that RE800 is the most compatible with Dap’s I owe AK120 and DX200. Also, I really appreciate its harmony with Dragonfly Black.



    RE800 is very musical and mid frequencies have nice level of detail but a little bit behind of the bass and the trebles in general spectrum. The lower mids are slightly recessed, but it is not bothered too much, so you don't feel any lack of mid. RE800 doesn't play mid frequencies that bold and meaty, so those who love that kind of mid can find it a bit weak. Actually, I was waiting full body sound and bold presentation but when I played the song, I heard clean, bright and highly resolved sound. The separation of mids are very successful. The upper mids are bright but its control is really good. Whenever I listen to the fast passages I observed it's rarely losing the control, in my opinion it is due to the recording and sources. The vocals are neither behind nor front but its recessive in overall presentation which defining RE800 as slightly V-shape. My personal taste is to hear closer vocals but I barely find it. The vocals are a bit recessed. I found female vocals slightly better than male vocals. The reason of it is the mid frequencies have thin notes.



    I am not a bass-head but the most important frequencies of a headphone are bass for me. The RE800’s bass is not so powerful as a bass headphone but it can go deep when it calls. Actually, I can say that many users are going to like the bass tone and quantity of RE800. Bass is not very authoritative in the overall presentation but as I mention before, if there is bass in the music, it is not shy to rumble. I tried to test bass quantity, listened to the EDM music and I can easily say that I am satisfied with it. Apart from that the amount of bass in popular genres is more than enough. Bass frequencies doesn’t take up much room on the general spectrum, they don’t have a negative effect on the background. Also, it doesn’t dominate the other frequencies. The speed of bass is much faster than I expected. It achieves fast passages without losing its resolution and detail. it is able to hit hard, extend and go deep whenever it is necessary. While I listen to EDM I think the bass speed is quite high for a dynamic driver but it doesn't reach to the speed of balanced armature driver. Bass is lightly emphasis and controlled. Overall, bass level meets expectations in terms of timbre, quality and details.



    The width of the soundstage is as like as an open-back headphone. In spite of the width of soundstage, instruments do not spread around, rather they can be distinguished easily. it offers a spacious concert by means of the wide soundstage. The separation of the instruments is extremely good and it is possible to position them in the track. Instruments are perceivable due to high resolution.



    The RE800 has a bright presentation with wide and deep soundstage, high instrumental separation, natural and refine tune. The resolution is extremely high that I have never heard that before in this price range. The detail level of the trebles is much better than the more expensive earphones. I can say that I really liked the Hifiman RE800. Resolution and detailed presentation that should definitely not be ignored in this price range.

    HiFiMAN RE800 - Outstanding, Engaging, Vivid
    Written by Dobrescu George
    Published Oct 26, 2017
    Pros - Excellent Soundstage, Clear Sound, Detail and Microdetail Retrieval, Separation Between Instruments, Energetic Signature, Lots Of Treble, Well-Layered Bass, Top-Notch Sound, Flawless Comfort, Build Quality, Beautiful
    Cons - Treble Might Be A Bit Sharp For Some
    HiFiMAN RE800 - Outstanding, Engaging, Vibrant

    HiFiMAN brings a new contender to their high-end IEM offering! RE800 promises to do a lot with their Topology Diaphragm, technology also found in their bigger brother, RE2000.



    HiFiMAN electronics has been a huge company in the Audiophile Industry for a while now, and they made a big name for themselves with well-known products like their HE-560 and HE-1000. Founded in 2005 by Dr. Fang Bian, HiFiMAN has been refining their IEMs and headphones offerings ever since.

    HiFiMAN also made some of the best-known audiophile DAPs, like the HM-901 DAP, which has been held in the hearts of the fans for a long time as having one of the sweetest sounds they ever heard.


    It should be mentioned that, like IE800, RE800 is a single Dynamic Driver IEM, and it doesn't rely on multi-BA setups. The main feature is the lightweight driver made under the Topolgy Driver Diaphragm name, a technology that proposes to make drivers that respond even faster to impulse than the typical dynamic driver, leading more details and better precision.

    I have absolutely no affiliation with HiFiMAN Electronics, I am not receiving any incentive for this review or to sweeten things out. This review will be as objective as possible and it reflects my personal experience with RE800. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in RE800 find their next music companion. This review is part of a small tour organized by HiFiMAN for their newly released products and my opinions have been taken after having used RE800 for at least two months, enough time to accommodate with the sound and all the details about this wonderful IEM.

    About me

    My name is George Dobrescu and I am the Director of the Seventh Heart Studios game studio. I work as one of the main programmers for the company, and I am the writer for Quantum Magica and Falsetto Memories projects. I spend eight – twelve hours a day working on a computer, writing and sometimes drawing. I also take care of administrative work which means that I require a portable setup so I'll be testing the portability of iDSD as well.

    Music is present all around me for a big part of that time as working with music is always more fun. With all the devices I own, I need great sound, comfort and ease of usage, not to mention that my listening volume ranges from "please stop that, it's far too loud" to "I can't even tell that you're listening to music".

    My collection includes everything from Classical to Metal, from Rap to Pop, from Punk to Cabaret and absolutely everything in between. There are great artists from every type of music, and I'm one to collect their albums, and keep a tidy order for my files.

    You can check out more about our games on our pages https://www.facebook.com/seventh.heart.studios/ and https://twitter.com/7heartstudios .

    At Seventh Heart Studios, we all love music and this has had an impact on our games as we hold the music close to our hearts and we are committed to only use ogg -q10 as the encoding format for our music since it offers the best disk space to sound quality ratio, OGG -q10 being closest to audibly transparent when compared to FLAC encoding.

    Personal philosophy: Music is more than a hobby or sound. Music is inspiration. Music is life. Music has meaning by itself, being the one thing that can define one's life while shaping one's imagination and creativity. Music can open doors to new plains and music can change one's mood. Music can rest the mind better than days of sleep or can give one energy better than a thousand cups of coffee. Music can be anything we want it to be and the music we experience using professional audition tools is more but at the same time it is nothing more than our way of enhancing the emotion we get from music. Love is a concept too shallow, unable to encompass what music really means to a music lover.

    First Impression

    When it comes to high-end IEMs, I have owned quite a few by now, and while it might seem ironic, HiFiMAN's own RE2000 is one of the best IEMs out there, high in the top with other well-renown IEMs. RE800 and RE2000 both rely on a single Dynamic Driver setup, comparable with Sennheiser ie800, in technology, since ie800 is also a TOTL (Top-Of-The-Line) IEM which employs a Single Dynamic Driver setup.


    I have owned quite a few IEMs and headphones before, Ultrasone DJ One Pro, Meze 99 Classics, Ultrasone Signature Studio, Dunu DK-3001, Sennheiser ie800, HiFiMAN RE-2000, Oriveti New Primacy, Kinera H3, FiiO F9, Beyerdynamic Xelento, and a few others. I also owned high end sources like DAPs (Opus #3, iBasso DX200, Opus #2, FiiO X7mkii), and high-end DAC/AMPs (iFi iDSD Black Label).

    I actually received the RE800 as part of a package from HiFiMAN Electronics, being part of the tour for their newly released products, and this time, the package arrived in a pretty funny way. I must commend HiFiMAN's communication and support as the package almost got lost on the road, and they provided great amounts of effort to help me receive the package safely.

    It was a rainy day when I first took RE800 out for a listen. Describing the weather that day as rain is too little to be said, the aphotic skies vaguely resembled the end of the world, thunderous applauses from above shaking the buildings from their grounds. The clock stroke around mid noon when I noticed that I have no provisions left and that I should go purchase some. I quickly dressed up, took on my coat and plugged RE800 in Opus #3 and prepared to challenge the nature itself for nutrition and survival. The bleak walls of my room felt as if they were melting down on me as the rain was pulling more and more force in each drop. Disheartened, I took a few steps out of the room and pressed play. A shock went through me like a lightning as I wandered through the corridors. A sweet melody dazzled my mind far into a fantasy world as my ears were tickled and delighted by sweet symphonies coming from RE800 and Machinae Supremacy's music. A quick thrill ran down my spine as multiple layers of sweet guitars and glazing cymbals were presented by this little golden IEM. Everything got brighter in mere minutes. No rain could darken my mood anymore, not even the storms raging outside. It was time for more listening with RE800 and to see how it combines with other sources.


    First things first, let's get the packaging out of the way:











    HiFiMAN goes a step beyond when it comes to their packaging, RE800 coming in a rather mid-large sized wood box that bears all the accessories needed within. The presentation is quite luxurious, especially considering that most IEMs up to this price point come in cardboard boxes.

    Although the tips included might work and should work for most people, I actually borrowed the Spinfit tips that came with Dunu DK-3001 for my sonic impressions.

    The metallic-grey wooden box comes packaged in a smooth cartoon paper that includes a few bits of information about RE-800, like a presentative photo, the Frequency Response, which is 5Hz – 20kHz, the impedance, which is 60OHM, and the sensitivity, which is about 105 dB. HiFiMAN wants to note their users that RE800 are electroplated with a gold finish, by having a sticker mentioning this in the upper left corner of the paper wrap.

    The metallic-grey wooden box is simple, elegant, and on the top side you will find the logo of HiFiMAN and the model name.

    HiFiMAN's slogan is pretty cool, "Innovating the Art of Listening", and we are going to look how much HiFiMAN delivers on their slogan in the sonic and usage aspect of RE800.

    Inside the wooden box, you will find RE800 In Ear Monitors, a carry box (that proven to be quite useful and practical), a selection of tips, both Comply and double/triple flanged tips, and plastic earhooks. The selection of accessories is quite good, and RE800 comes with enough to enjoy them. It should be noted that the official current version of RE800 comes with detachable cables as well.

    RE800 comes with a high-quality, beautifully designed owner's book, that includes a lot of useful information. It was enlightening to read about HiFiMAN's quondam models, like RE600 and their first headphones.

    The wooden case in which RE800 is packaged will come in handy for keeping other audio-related equipment, especially as it is padded with a soft, velvety material that will caress your audio items, keeping them in good condition and gently defending them from scratches.












    To recap, RE800 comes with:

    - Foam tips

    - EarHooks

    - Single Flange tips

    - 2-Flange tips

    - 3-Flange tips

    - Owner's Guide

    - Earphone Travel Case

    - Premium Wooden Case

    - RE800 IEMs

    All in all, a good package for a good-looking IEM.

    What you should look for when considering a IEM (In-Ear Monitor)

    When purchasing an IEM, there are a few factors you should take into account to ensure that you’ll have the best experience possible. Sooner or later, all those factors will come into play, one way or another:

    - Sound quality – This is, by far, the most important aspect of every purchase, when you invest in high end audio products. The sonic characteristics, along with the frequency response / sonic signature widely differs from IEM to IEM.

    - Comfort / ergonomics – The fit and comfort are quite important, especially if you plan on using the same IEM for hours in a row, or in a live performance.

    - Isolation – Every IEM will offer some degree of isolation, but there are both models that focus on ultra-isolation from the outside noise, and open models.

    - Good Value – Always nice to have

    - Interesting/Intriguing design – Every user will have a personal preference and taste for what an “interesting design” is, but it is generally recommended to pick a IEM which you consider to be aesthetically pleasing, or in simpler words, Good Looking.

    - Drive-Factor – How easy it is to drive and how prone to hissing it is, since certain IEMs and headphones will require special sources to offer the best performance.

    - Accessories included – It is better to have a large selection of tips and accessories included with a IEM, especially for those that feature unique tips or require their own accessories.

    - Build Quality and Warranty – While it is good to have a solid warranty included with Every IEM, having a solid build quality is far better. Having best of both is the icing on the cake.

    Build Quality/Aesthetics

    From the moment you receive RE800, you know that you are dealing with a glamorous, top-end IEM, presented beautifully in a wooden box, and seated in a gentle velvety sponge cutout, which is covered in a luscious coating, RE800 appear like two golden jewels that are crying for attention.




    The IEMs themselves are made from Brass, a resilient alloy made from weaving in cooper and zinc, then they are electroplated in gold. HiFiMAN took great care to mention that their IEMs are caressed with the best of materials, to bring most enjoyment to the listener.

    The cables are supple, and are very flexible, providing an excellent option for both those who want to wear them straight-down and over-the-ear, sporting a very solid 3.5mm L-angled connector.

    The IEMs themselves have extremely small bodies which are smooth to the touch, providing gentle slopes and curves in their design for improved comfort and splendid design. Both IEMs housings have HiFiMAN's logo printed on the back, and they also have an L and R markings to notify the user of which is the left and which is the right earpiece.


    The only downside of RE800 might be that they don't have detachable cables, but soon after the initial release, HiFiMAN issued a recall and provided RE800 with fully replaceable cables to their users.

    With their minute sized bodies, RE800 can only be compared to IE800, which also have a keen look to their construction bodies, both being extremely comfortable, even for users with very small ear canals.

    The Travel Case is not branded, but it features a smooth rubbery texture on the outside, with a small pouch on the inside. At first, one could judge the Travel Case to be pretty frail, but I have thrown it in my bag, even under many heavy other objects, and it survived without a scratch, proving to be one of the best Travel Cases for IEMs out there.

    All in all, with their sweet golden color and their gentle bodies, RE800 look like two jewels and while they won't make anyone turn their head as they almost disappear inside one's ears, they sure are a cute and stylish IEM to see on the table and to analyze while you're not using it.

    Fit / Comfort

    Inside the Owner's Guide, HiFiMAN is proud to present that RE800 can be worn both straight down and Over-The-Ear. After testing, they proved to be wearable in both situations. Furthermore, they are extremely comfortable in both conditions, the IEMs, the bore sizes, and the tips usually being small and having a gentle contact with one's ears, providing excellent fit and comfort.


    Given that they are small IEMs, I am not sure if the largest provided tips are large enough for someone with larger ear canals, but since RE800 works with most aftermarket cables out there, I wouldn't worry about their fit in any way.

    I have actually been using the pair of Spinfit tips that came with the Dunu DK-3001 while using RE800 since Spinfit offers the best comfort for me, and I have to commend Dunu for including it and for opening my mind to those tips. It would be great if more companies would start to add Spinfit in their default tip selection, but HiFiMAN's default selection of double and triple flanged tips, along with Comply foam tips is fairly good as well.

    All in all, RE800 will be extremely comfortable for almost any user, and their fit should be excellent with all ears out there, given their small size. Even if a user wants to use a third party set of tips, this is easily doable since RE800 has a typical bore size and most third party tips will work with them flawlessly.


    HiFiMAN RE800 has been tested with Xiaomi Mi Max 2, FiiO X5ii, Opus #3, Opus #2, iBasso DX200, Hidizs AP200, Shanling M2s, FiiO X7mkii and with the benchmark DAC/AMP, iFi iDSD Black Label.


    RE800 can easily be driven from most portable sources, but given their rather revealing signature, they will answer well to using a better source. It should be noted that they have a somewhat odd impedance for a IEM, 60OHM, this aspect making them less sensitive to impedance matching and prone to work well with a wider array of sources, regardless of their output impedance.

    RE800 is not prone to hiss from any kind of sources, thing probably attributed their increased impedance, thing which makes them an excellent IEM to combine even with noisier sources.

    Sound Quaity

    HiFiMAN RE800 is a little energetic IEM that provides a lot of energy in the higher registers, an impactful, full, and natural bass, a natural yet slightly recessed midrange, and a very good instrument separation. Drums are snappy, voices have a natural tone and texture to them, especially male voices, and everything comes out sweet and musical, similar to how IE800 is pretty sweet and musical. The true-to-life tonality and bite in the upper registers will work amazingly well with Acoustic music.


    Although they are musical and natural for voices, RE800 is not free of coloration, providing a rather fun and engaging sound, with a little unique signature, which will appeal more to certain users. They are really good at expressing a well-extended sound in both bass and treble, they have enhanced and electrifying textures, and the detail and micro-detail presentation is over the top. The Topology Diaphragm Driver technology works very well for RE800's resolution and its sonic abilities, providing an exceedingly detailed yet fun, engaging, and musical sound.

    The signature can be described as vivid, vibrant, euphoric, deep, and energetic. There is a little dip somewhere in the 3.5 – 4 kHz area and a little peak in the ~6-8 kHz area, which leads to a sound that enhances acoustic guitars and acoustic instruments very nicely, providing them with more bite and vibrancy. Many IEMs go in the opposite direction and are cutting too much bite from acoustic guitars, so it is nice to see a different approach this. The layering RE800 provides is also insanely good, being up there in the top with the best IEMs.

    Little disclaimer

    All sonic impressions for RE800 have been taken with DX200, Opus #2, M2s, AP200, X7mkii and iDSD BL, all of those being impressive audio devices, each having a signature of its own. All sources will influence the sound more or less, but RE800 has a certain sonic character that is present with all sources. Some sources might tone down or change the initial signature provided by RE800, while other sources will enhance their natural signature.

    Channel balance

    RE800 seems to have an excellent channel balance and there is no aberration to be detected.


    The Bass of RE800 is excellently well extended, down to the lowest registers with no roll-off, providing an excellent impact and resolution. RE800 is able to resolve micro-textures and minute-level details quite well, Hip-Hop music feeling quite vivid and detailed. Natural and acoustic instruments have an excellent timing and RE800 manages to sound very natural, providing the level of texturization and depth you would expect when hearing a live double-bass or other bass instruments.

    The impact and depth are above what one would expect from a IEM with such small housings, the bass is deep, and provides earth-shattering levels of impact, but doesn't really go overboard, having no traces of bloat. It is like RE800 has an enhanced bass, but a bass that keeps its timing tight and its resolving abilities straight while still being quite enhanced.

    Fara zahar – Starea Natiunii – This is the first time Romanian music is added to the song impressions list, but we have to take into account that there are excellent Romanian artists out there. Fara Zahar is a Romanian Folk / Parody / Avant-Garde – Pop band that had excellent recording and mastering for their 2008 album, Neamul Lui Penes Curcanul. All of those are supposed to be comedy songs, but they still sound excellent through RE800, providing a different outlook on this type of music. The song starts with an outstanding guitar composition accompanied by a deep and large bass playing in the foreground. Voices sound natural and have a very true-to-life tonality and texture to them, RE800 making them feel more like a live presentation rather than a recorded piece listened through IEMs. The acoustic guitars play with amazing detail and a sweet tonality. The drums sound very crispy and detailed, and the whole composition is playful, dynamic and enjoyable. The message about the condition of Romania from back in 2008 sounds sweet and funny, RE800 proving to be an excellent IEM to play the songs of Fara Zahar.

    The Tiger Lillies – Killer – Since RE800 is best at acoustic music, let's explore another band that employs a strong combination of both gentle and harder acoustic instruments, The Tiger Lillies. Their song Killer is an excellent test-song due to its good mastering. After the theatrical intro, the song starts with a very groovy, large and impactful bass line, played along a quick and snappy accordion and a gentle drum and snare pattern. The voice is very clean and clear, providing an excellent driving mechanism for the entire song. The story about how the singer could have been a killer is sent forward with amazing emotional depth and convincing statement. Although TTL is a comedy / Avant-Garde band, the song feels quite real and the instruments are rather tangible.

    Ленинград – Комон эврибади – Leningrad is one of the best-known bands of Parody, Comedy and Avant-Garde music from Russia. Their compositions and songs have millions of lovers world-wide and their playful and melodic style has impressed many already. The song starts with a playful combination of guitars and drums that are quickly followed by the trumpets and the rather hoarse voice of the lead singer. The voice feels natural, as if the singer is next to the listener, and the smoothing that is sometimes applied is absent, leading to a very vivid experience. The bass is always deep and heavy, played with a natural decay, and offers a convincing sound of a real-life bass guitar. The trumpets and other blow instruments are presented very energetic and vivid, and the cymbals bear a realistic vibrancy to them.


    The Midrange of RE800 is an open experience, as they provide a very convincing soundstage and instrument separation, especially with Spinfit tips and Mandarin tips. The tonality of the midrange is excellent for Acoustic music and Pop, but might sound a bit hot for some of the harsher Metal music. I love how they sound with metal, as they render it quite vivid, but it should be noted that cymbal hits come a bit hot. There is a overly nice sweetness to the sound of a violin and to the sound of an acoustic guitar when playing a ballad, along with a certain sense of rhythm to all music.

    RE800 can be tamed and treated to sound leaner with a bit of EQ, feeling a bit like a wild animal, that can be tamed and taught to do anything the user desires.

    A static Lullaby – Toxic (Cover) – This song is a part of the "Punk Goes Pop" compilation, an excellent set of pop songs performed by punk, rock, and metal bands. The song starts with an engaging combination of acoustic guitar notes, followed by natural voice meddled with sweet rhythm guitars and snappy drums. Everything is kept in its own place and presented with a good amount of space and air between the instruments, RE800 being really good at presenting music in a well-separated way. The cymbals have an exquisite energy about them, and this enhances the detail and the micro-detail levels, bringing forward many nuances that are otherwise subdued form this song, like the background synth sounds and the fine textures in the rhythm guitars. The story about the toxic love that becomes addictive to the one feeling it is felt vividly and presented with a good amount of emotional involvement.

    Rings Of Saturn – The Heavens Have Fallen – The instrumental composition by the rather heavy band, Rings of Saturn, starts with a sweet combination of synth notes woven together, giving the listener an introduction to the parallel plane he is going to explore through the song. When the song starts, it starts with great impact and it pushes the listener forward in the sixth dimension, quickly playing with all his senses. The vibrant solo guitars woven with sweet rhythm guitars played along a snappy, quick, yet powerful drum set sends the listener's mind dreaming at thousands of stars flowing through the space-time continuum. The solos are sweet and delicate, yet bear great amounts of power and emotion. The message of this instrumental song, unclear, yet vividly presented, about the universe as a whole, its creation, and unavoidable ascension throws the listener into both a listening craze, and a sweet meditation about life and its meaning.

    The Offspring – Cool To Hate – This old-school punk song starts with an picturesque and vintage atmosphere representing America during the year the album was recorded in, about 1997. Guitars are always presented with a good amount of texture and sweetness to them, while the voices always sound natural and come through with a good amount of power, yet never sound harsh. The cymbals are presented with a good amount of force and life in them, providing a vivid experience for the listener. The story about the protagonist, the negativistic teenager we all once been, hating everything, is transmitted on a fun and happy tone, almost like listening to a happy tune about happy teens, but with the opposite message.


    HiFiMAN RE800 has a unique way of conveying the treble, adding a lot of energy and life to the cymbals and other instruments that have a lot of content in the lower treble, like trumpets. This makes RE800 an excellent IEM for well-recorded music and music that has a very honest treble presentation, like acoustic music. On the other hand, metal music can sound a bit hot for some, RE800 having a small enhancement in that area.

    This unique way of presenting the treble with a lot of energy makes RE800 stand out in clarity, detail, micro-details and honesty, giving them a strong edge when it comes to having a life-like presentation.

    Besides the energetic side of the treble, it is good to mention that RE800 are quite detailed and that their treble sounds rather solid, especially compared with something like IE800 which has a softer sound to their treble, albeit having an energetic top end as well.

    Machinae Supremacy – The Greatest Show On The Earth – The song starts with a few feeble and shy guitar notes played together, like children playing gleefully through hidden woods. The song starts strong with a series of sweet guitar notes. The voices always sound natural, never being harsh or overexposed, and they are accompanied by gentle sound of bells and other special effects. The bass keeps being quite strong through the song, but it doesn't shadow the sweet midrange. The top end of the song is always presented vividly, with the cymbals having a tiny peak to them, yet without feeling harsh or over the board.

    Jason Derulo – Talk Dirty – A good test track, to show what RE800 can do with a heavily compressed pop song that features extreme amounts of bass. The song starts with a good amount of drums/effects played in an airy and open space. There is a good sense of rhythm and playfulness with the whole song, the bass is heavy and goes very deep, but it is well controlled and provides an excellent clarity and texture, whilst keeping good amounts of control. Voices are clear, natural and sound very clear as well. The background voices are also vivid and presented with good amounts of life to them. The jazzy blow instruments are vibrant, but they don't go over the top, staying quite playful rather than being stringent. The enhancements in RE800's treble don't bother at all, and RE800 does an amazing job at playing pop music. The story of the song feels real, and although this song doesn't have a necessarily interesting or nice story, it is good to know that RE800 has the ability to present it well.

    Rob Zombie – Werewolf baby – Rob Zombie's songs are always good to test with all equipment. Excellent recording, mastering and post production conditions make Rob Zombie's music some of the best out there. The song starts with a funky yet playful combination of rhythm and lead guitars played along quick and rowdy drum sets. The voices feel realistic, and the whole song is presented in a large and open space, with a very good separation between the musical instruments. The song chorus is vivid and playful, being quite easy to move your head while listening to this scary yet addictive song by Rob Zombie. The story about the man who becomes the werewolf is presented in a dark yet fun light, almost like a painting about Rob Zombie's movies, where the watcher almost sympathizes with the antagonists.


    HiFiMAN RE800 has quite an expansive soundstage, especially considering their physical size and what one would expect form them before plugging them in. Most IEMs that feature a deep insertion, or small IEM bodies, will have a more intimate soundstage presentation, but RE800 seems to do its best to defy this logic, providing an excellent all-around soundstage. Special effects in the music of Escape the Fate can come from quite far away, there are certain instruments that feel as if they are played above or below the listener, and there is a very good general sense of space and air, all instruments being able to breathe as they should.

    The instrument separation is very good as well, comparable with the mighty Sennheiser IE800, a TOTL IEM priced similarly to RE800. The listener can easily tell different instruments and instrument layers apart from each other, it is very easy to identify every single nuance in every unique instrument.


    HiFiMAN RE800 has a uniquely quick driver, which leads to a very life-like presentation of the ADSR (Attack, Decay, Sustain, Release) / PRaT (Pace, Rhythm and Timing). The Attack of each note is quick and RE800 gives acoustic instruments an especially natural presentation, with all the natural textures and enhancements they are supposed to have. Listening to RE800 can easily lead to tapping your feet while listening to rhythmic electronic or while hearing the sweet Jazzy melodies sang as if they were played right in front of you.


    The rather large and impactful bass presentation doesn't hinder quick rendering of other elements, the ADSR being quick enough to present all details and micro-details, even while RE800 has large amounts of bass impact.

    Electronic guitars have a uniquely enhanced texture representation, that is probably a characteristic of the unique Topology driver designed by HiFiMAN. All in all, there is no space to complain about the ADSR / PRaT, even at their rather high price.

    Portable Usage

    RE800 has been thought and designed to be a portable IEM, starting with the small IEM bodies, excellent ergonomics, and their easy-to-drive nature.


    The cables are designed to be portable as well, with their supple and flexible construction. It is good to mention that the cables provide very little to no cable noise (microphonic noise), and they are quite comfortable to wear, being light enough to allow for walking and doing other activities while wearing RE800.

    The isolation of RE800 will be dependent on the tips used, my personal favorites, the Spinfit tips and the Mandarin tips both offering an excellent amount of isolation from the outside noise. It is possible to use RE800 at low levels while taking a walk through the thunderous streets of Bucharest, as RE800 is able to defend the listener from most of that commotion.

    Drive factor

    HiFiMAN RE800 is fairly easy to drive, and while it can be driven from almost any smartphone, and even sound great as such, adding a professional DAP (Digital Audio Player), or a DAC/AMP, will surely enhance the experience and will help the sound become not just great, but amazing. RE800 is not particularly sensitive to hiss, and seems to work pretty well with most sources it was tested with, but it is fair to mention that depending on the listener's tastes, some sources might provide a better synergy.

    Select pairings

    RE800 + iDSD BL – The acoustic genius playing along the TOTL benchmark DAC/AMP is a totally sweet combination. RE800 doesn't need the switches on iDSD BL to be engaged, as it has a very good sound just by being driven by it. The unique signature of iDSD BL will sweeten the midrange of RE800, giving them even more musical edge and widening the types of music it works best with. iDSD BL will enhance the bass impact and the treble clarity of RE800 a bit, but it won't make them harsh nor increase the peaks they have, making a very good companion for details and musicality. iDSD BL will also enhance the soundstage size of RE800 by a good amount.

    RE800 + iBasso DX200 (AMP1) – This is a very recommended pairing for RE800 since iBasso DX200 is the neutral master of DAPs, providing a very linear, yet musical and detailed sound. As such, it doesn't increase the bass nor the treble of RE800, but it will enhance the dynamics and textures, giving RE800 even more detail, without taking away any of the musicality they present to the listener. DX200 is also one of the best DAPs when it comes to its instrument separation, further enhancing the instrument separation of RE800. Since this is the SE version of RE800 with no removable cables, it was impossible to test DX200 + AMP3 with RE800. Commercial versions should have interchangeable cables, providing option for balanced cables as well.

    RE800 + Opus #2 – Opus #2 makes an excellent companion for RE800, being one of the DAPs I used a lot with it. The sound can be described as sweet and musical. Opus in general has a sweet spot for sounding musical and for playing things with a lively energy in the mids, along with a large bass impact. The organic Opus sound will enhance the vocals presented through RE800, giving them an edge when it comes to smoothness in the midrange and lifelike tonality. Opus DAPs are also known to have large and expansive soundstages, providing an intricately wide and well-separated presentation for music played through RE800.

    RE800 + Shanling M2s – A portable, light, yet powerful combination, Shanling M2s is known to bring a lot of sparkle and bass hit to the IEMs connected to it, being a bit U shaped. M2s will smooth some of the detail in RE800, making them a bit laid back and offering a relaxed experience, without taking away any of the vibrancy and life from the sound.

    RE800 + Hidizs AP200 – AP200 is an excellent DAP if you're looking at offering RE800 an upper midrange companion to compliment their sound. AP200 is a bit U shaped by its nature and comes with a smooth midrange that doesn't enhance aggressiveness, but rather gives music a laid-back presentation that feels detailed yet smooth. The highlight of AP200 would be its rather natural tone in the midrange, enhancing the acoustic experience with RE800, without adding any harshness or aggressiveness.

    RE800 + FiiO X7mkii – FiiO X7mkii is an energetic performer with a lot of life in the midrange and an explosively fun presentation. The midrange of the combo is sweet and X7mkii will sweeten the midrange of RE800 by a good degree, giving them a rather happy and vibrant presentation, along with a nicely layered sound. X7mkii also has a natural type of bass that will enhance the bass impact RE800 naturally has, along with the rather quick sound, giving them an edge when it comes to speedy music.


    HiFiMAN RE800 has been tested against EMI and they don't pick any EMI (Electro-Magnetic Interference) from any source, regardless whether they are used under high-tension power sources or right next to a wireless router.


    Although they are priced in the high-end range of IEMs (considering that anything above 500$ is already a high-end IEM priced as such) RE800 has to do a lot for themselves to justify their 800$ price tag.




    RE800 vs Dunu DK-3001 – Although there is some difference in their price tags, DK-3001 makes an interest competition for RE800. Starting with the bottom end, DK-3001 presents bass with a slower decay, while RE800 is quicker, both providing really good impact and control abilities. The midrange is a bit more V shaped on RE800, where it feels a tad more linear on DK-3001, both having a pretty natural tonality and texture presentation. RE800's top end is enhanced when compared to DK-3001, the presentation highlighting details and fine nuances more on RE800, although DK-3001 doesn't try to do that, but rather to offer a relaxed presentation to the music. All in all, DK-3001 is more of a complementary IEM to RE800, being a smooth and laid-back presentation, while RE800 is vibrant and energetic, with an inherent tendency for presenting more details.

    RE800 vs Oriveti New Primacy – ONP is priced considerably lower than RE800, but still makes an interesting comparison to RE800. ONP has less bass, having a tighter bottom end. The midrange is quite sweet on both, its midrange being ONP's highlight, while RE800 has a somewhat more recessed midrange. The top end is smoother and less enhanced on ONP, leading to an inherently more detailed sound on RE800.

    RE800 vs ER4-XR – Although we visited this comparison once before, it is good to do it using RE800 as a point of reference. In direct comparison, ER4-XR has a tighter bottom end, while RE800 provides somewhat more impact, with a larger bass. The midrange is very forward on ER4-XR, while it is slightly recessed on RE800. The treble is considerably enhanced on RE800, which affects the way top-end microdetails are presented, but ER4-XR puts up a very good fight when it comes to the midrange details. The soundstage is larger on RE800, along with a more vivid instrument separation, ER4-XR blending the instruments more to create a "whole" sound while RE800 defines each instrument as its own unique entity.

    RE800 vs HiFiMAN RE2000 – RE2000 is far more expensive than RE800, being more of an ultra-high-end concept IEM, produced by the same company. RE800 has a more enhanced and a little slower bass, while RE2000's bass is closer to a natural sound, with a quicker decay, but still presenting a lot of impact. The midrange is less V-shaped on RE2000, and the tonality goes one step further into being quite life-like and natural, RE2000 having an even better texture presentation, although RE800 still puts up a very good fight, showing that they have the inherent qualities provided by the same topology driver technology. The top end is more natural and less peaky on RE2000, while RE800's top end provides a better match for acoustic music, and micro-details enhancement, where it is very hard to match its performance. All in all, RE2000 is a very nice upgrade to RE800, and some the sound characteristics present in RE2000, inherent to their technology, are also present in RE800.

    RE800 vs Sennheiser ie800 – This is probably the most interesting comparison, especially since ie800 is priced similarly to RE800, and has a similar signature, with a strong top end, and a deep bottom end, and with a rather recessed midrange. Starting with the bottom end, both RE800 and ie800 provide a very nice presentation, with ie800 having a bit more sub-bass quantity than RE800, while both have very good amounts of control. RE800 has a bit more midbass enhancement which leads to a slightly thicker sound than ie800. The midrange is quite detailed on both, and while both have a similar level of instrument separation, RE800 glazes music with a slightly larger soundstage, while ie800 presents music more intimately. The top end is where they sound more different than similar, RE800 having a little peak around 6-9 kHz, then slowly going down, while ie800 has a larger treble area enhanced, leading to a softer sound, with even more treble. Both are energetic, but the cymbals sound rather soft on ie800 and harder on RE800. The detail levels are quite similar, and it is hard to choose between them, both of them being amazing performers, with excellent fit, ergonomics and sound. Ie800 looks like it is made of obsidian / ceramic, while RE800 is made out of golden brass, each adding some inherent sheen to the sound.

    RE800 vs Beyerdynamic Xelento – Beyerdynamic Xelento is more of a complementary IEM to RE800 rather than a competitor, since Xelento goes for a far more balanced, natural, and smoother approach. Both RE800 and Xelento are extremely musical, but they present the music quite differently, Xelento being quite the romantic performer, while RE800 sounds a bit more like the technical-musical performer, especially due to their treble enhancement. Xelento's top end is the biggest difference from RE800, where Xelento doesn't have any peak the top end, but a smoother top end when compared to RE800, providing a leaner sound that can feel a bit more natural, compared to RE800's energetic and vibrant approach.


    HiFiMAN RE800 is priced at around 800$, being one of the more sophisticated and luxurious high-end IEMs around.

    Looking at the package content, they come in a wooden box, which is quite rare. They come with a good selection of tips, although SpinFit or Mandarins are recommended as a little, very inexpensive addon.


    The sound is exceptional, even for this price point, and RE800 is one of the very impressive performers out there, a rather exclusive and engaging IEM.

    The more interesting part about the value is the cable, which was not detachable on the model reviewed, but at the same price HiFiMAN released a RE800 IEM with detachable cables. Since this was one of the only gripes most users could had had with RE800 at this price point, HiFiMAN's move to release a detachable cable version of RE800 places RE800's value from average to a very good value. They don't cost less, but having detachable cables makes them a far greater value, providing a good balance of sound, ergonomics and futureproofing for the price paid.

    All in all, there is no space to complain about the price, since they are one of the more glamorous high-end IEMs with a few bells and whistles to check your list.


    HiFiMAN RE800 has been one of the most interesting IEMs to look at, with their golden looks and supple yet curved bodies. The sound matches both the looks and the price point, although at times the sound is actually much better than one would expect it to be, given their rather petite size. RE800 comes to refresh the 800$ price range with the addition of HiFiMAN's Topology Driver, which brings more speed to the dynamic driver, and enhances the transient response of a IEM, leading to more details and an enhancement in the naturalness of the sound.



    While RE800 comes with maybe a little too few tips, they come with comply tips, which are favored by many. Purchasing matching Spinfit or Mandarin tips is quite easy and inexpensive, and could further enhance the listening experience when using RE800, at a very small fraction of their price.

    Purchasing the version of the detachable cable of RE800 will futureproof them a bit, leading to a rather good purchase of a high-end IEM that is not to be taken lightly, despite their nimble size and beautiful aesthetics.

    So far, HiFiMAN delivers on their word, and RE800 is a IEM that innovates the art of listening, providing excellent fit, clarity, detail levels, bass impact, treble energy, and a beautiful look.

    If you like a sound that is well-separated, has a great bass with extreme impact, a sweet midrange and an enthused top end that matches acoustic music, and gives life to acoustic guitars, RE800 might be just the IEM you're looking for, a truly amazing listening experience in a small package.

    Thank you for reading, and remember to have fun while listening to music!

    Written by audio123
    Published Apr 20, 2018
    Pros - Agile Bass Presentation, Energetic Treble, Build Quality
    Cons - Midrange can be lusher

    HiFiMAN is a Chinese company that specializes in producing in-ear monitors and headphones. Recently, they have released the RE800 and their flagship RE2000. For the RE800, I have received the latest version which features detachable cables. I would like to thank HiFiMAN for this review unit. At this point in time, you can purchase the RE800 from https://www.amazon.com/HIFIMAN-RE800/dp/B071YN9QJR/



    Frequency Response : 5Hz-20kHz
    Impedance : 60Ω
    Sensitivity : 105dB
    Weight : 0.95oz (27g)

    Unboxing & Accessories

    The HiFiMAN RE800 comes in a silver hard rectangular case that has the brand name and model name printed on it. It has a protective cover that shows an image of the RE800. Inside the hard case, there are 2 small packages and a hard circular carrying case. For the 2 small packages, the first one contains a detachable mmcx cable while the other one contains eartips. On the top of the carrying case, there is the brand name printed on it with the iem inside it. Under the foam, there is a pack of tips that contains Comply foam tips, 1 pair of ear-guides, 1 warranty card and 1 instruction manual. The overall package has a premium feel to it.






    IEM Build & Design

    The RE800 has a fine 24k gold finish to its surface and it has a rather oval shape. On the faceplate, there is the Hifiman logo printed on it. The shell is made of brass with a strong build quality. At the bottom of the iem shell, there is a vent. There is also another vent near the nozzle. The nozzle is straight with a metal mesh for earwax prevention. It is rather small and not heavy at all. I am able to fit the RE800 comfortably in my ears. The RE800 has mmcx sockets. Overall, the iem is beautiful in its aesthetics and constructed well.





    Cable Build & Design

    The cable included is made of silver coated crystalline copper wire. It is not braided and has a 2 core design. The overall build quality on the cable is good and there is a soft-like transparent rubber coating on the wire itself. There is no memory wire section. On each mmcx connectors, there is L & R markings to differentiate between left and right. For the left, it is blue in colour while for the right, it is red in colour. The connectors has a transparent housing. The chin slider is a circular gold ring while the y-splitter has the brand name and model name printed on it. It is gold in colour too. Moving on to the jack, it is 3.5mm gold plated with strain relief.


    Sound Analysis


    The RE800 extends its sub-bass with authority and confidence. There is a quick rumble to it. It is typical of a dynamic driver’s bass reproduction. The presentation of the bass is clean and technical. There is sufficient punch from the RE800 and each bass note is being portrayed with precision. With an agile nature, it packs energy. The bass texture is very smooth and decay is quick. The bass articulation is accurate and on point. With such an energetic nature, the bass is very enjoyable and exciting to listen to. The transition to the lower mids is good with a smooth passage.


    The midrange on the RE800 operates in a transparent and clinical approach. The lower mids on the RE800 has sufficient quantity to tackle male vocals. Though it does not have huge amount, the lower mids is expressed with musicality and texture. The upper mids is quite forward and there is a good intimate presentation. There is sweetness from the upper mids. Female vocals sound euphoric here. The midrange definition is clear and operates at a high standard with a good level of details retrieval.


    The treble has a good extension with no grain. There is no sibilance and harshness. Treble articulation is precise with a good crisp. The body is rather appropriate. Texture is not very smooth. It operates in a bright approach with a good amount of air at the top end. The air gives space to the overall presentation and lightens it. The details shown is in abundance and there is good clarity.


    The RE800 tackles both the width and depth of soundstage rather well. The positioning of vocals and instruments is presented precisely with no congestion. There is a good depth with a great amount of space. The RE800 has a quick expansion in its soundstage and there is a good open feel.



    HiFiMAN RE800 vs Beyerdynamic Xelento

    The RE800 has less sub-bass extension than the Xelento and it has more quantity. I feel both presents their sub-bass in an authoritative and punchy manner. There is agility in each bass note. The mid-bass on RE800 has more body to it while the Xelento tackles its mid-bass with pace. Xelento has a slight edge in its bass decay. Bass texture on the RE800 is smoother. The impact brought by the Xelento is more and there is more engagement. The lower mids on the RE800 has more body and male vocals are presented with more thickness. The upper mids on the Xelento is more forward. There is more crisp and definition on the Xelento. Female vocals benefit heavily from it. Moving on to the treble section, the Xelento is more extended. There is no sibilance and harshness on both. The amount of air rendered is slightly more on the RE800. For soundstage, both have a very similar width and there is a natural expansion. The depth on the Xelento is slightly better with more space. There is no congestion on both.

    HiFiMAN RE800 vs Campfire Audio Vega

    The Vega has more sub-bass quantity than the RE800 and there is more extension. Vega stretches it more and the depth is shown. The bass presentation on the Vega is more authoritative and there is more mid-bass slam. The Vega approaches it in a heavier approach while the RE800 presents it in a delicate and lighter manner. The RE800 showcases it agility here. The lower mids on the Vega has slightly more body than the RE800. I find the RE800 to have more pace but the impact brought by the Vega is greater. The upper mids on the RE800 is more crisp. Both have good definition. Female vocals is more controlled on the RE800. The presentation is better with mastery. Next, in the treble section, the extension on the Vega stretches more. There is slight harshness on the Vega. The air rendered on both is very similar. In terms of soundstage, the Vega has slightly more width and the depth on the RE800 is better.

    HiFiMAN RE800 vs DITA Answer

    The sub-bass on the RE800 is extended better than the Answer. There is slight grain for the Answer. Bass texture on the RE800 is presented more smoothly. The decay on both is similar. I find the rumble on the RE800 to be more musical. The mid-bass on both is similar in the slam. Bass note on the RE800 is presented with more agility than the Answer. The RE800 has more body in the lower mids and male vocals are presented better. The upper mids on the RE800 has more control and the forwardness has more magnitude. For the treble, Answer is slightly more shouty than the RE800. The RE800 presents the treble with finesse. Articulation is much more precise. There is slight harshness on the Answer. The amount of air on the RE800 is more. Answer has a slight sparkle. For the soundstage, RE800 has more width and depth. Vocals and instruments positioning is rather accurate.


    The HiFiMAN RE800 is a brilliant dynamic driver iem that boasts an agile bass presentation and controlled treble. It provides an energetic sound that has a high level of engagement. Furthermore, it comes in a premium package with many accessories. HiFiMAN has delivered again with the impressive RE800.

    Treble-head Golden IEM
    Written by earfonia
    Published Mar 20, 2018
    Pros - Good build quality.
    Small size with excellent fit and comfort.
    Good clarity and transparency.
    Cons - Pricey.
    Polarized towards bright tonality, therefore not an all-rounder IEM. The Lean bass and midrange make it tends to sound good on a certain type of recordings but not so good on others.
    60 ohms impedance is not very smartphone friendly.

    Big thanks to AV One Singapore for the opportunity to loan the demo set of Hifiman RE800!
    I should have posted this review many months back, but there was a sudden peak on my workload that forced me to temporarily halt the completion of this review. I guess better late than never, so here is my take on this golden IEM.

    The unit that I reviewed, as shown in the pictures, was the older type of RE800 with no detachable cable. From Hifiman website, I saw that they have upgraded the RE800 with a detachable cable.

    02 P1390405.jpg

    RE800 uses 9.2mm single dynamic driver with special coating technology by Hifiman that they called ‘Topology Diaphragm’. Diaphragm with special ‘nanoparticle’ coating on its surface that distributed in a distinct geometric pattern. The technology is said to reduce distortion and to achieve certain acoustic properties. We can read more explanation about it on the Hifiman website (link above). The IEM housing is made of Brass, electroplated with 24k gold. As for the cable Hifiman chose silver coated crystalline copper, selected from 30 different options. Hifiman seems to have put a lot of attention in the design of RE800. And at this price point, the expectation is high on this cute small golden IEM.

    My personal ratings based on the sound quality alone would be around 3.5 stars, mainly due to my personal preference of sound signature is rather different than the RE800 sound signature. I think treble-heads might rate it higher. I like the small size and comfort factor. The build quality and presentation are also good, therefore I think 4 stars is quite a reasonable rating for RE800. Especially considering Hifiman has listened to user feedback and improved RE800 with a detachable cable for the newer batch of RE800. Extra points there.

    • Good build quality.
    • Small size with excellent fit and comfort.
    • Good clarity and transparency.

    • Pricey.
    • Polarized towards bright tonality, therefore not an all-rounder IEM. The Lean bass and midrange make it tends to sound good on a certain type of recordings but not so good on others.
    • 60 ohms impedance is not very smartphone friendly.

    Suggestions for Improvement:
    • Improve value. For the sound quality it offers, in my opinion, RE800 is rather overpriced.
    • Improve bass and midrange tuning for a more balanced tonality.

    • Recommended IEM for treble-head, or those who prefer a higher level of clarity and transparency.
    • Best with classical and general acoustic instrumental recordings.
    • May not be suitable for those who are looking for IEM with full-bodied midrange and realistic sounding bass.

    Sound Quality

    Frequency response measurement in this review was done using MiniDSP UMIK-1 measurement microphone with a DIY acoustic coupler. The DIY acoustic coupler is not an industry standard acoustic coupler, therefore the measurement result is not absolute, and shouldn’t be used for comparison with other measurement result using different measurement equipment. The measurement result in this review is only useful to be used in this review, for comparison between different IEMs measured using the same system.

    05 IMG_0001.jpg

    After reading some reviews in Head-fi, I suspect that there might be more than 1 variant of tuning of RE800, that most probably not on purpose but could be due to production batch inconsistency. The demo unit from AV One Singapore sounds smooth bright and doesn’t seem to have the reported 7 kHz treble peak as reported by other reviewers. Some friends also share similar opinions that the demo unit from AV One Singapore does not suffer from the 7 kHz peak. My measurement also doesn’t show the 7 kHz peak. Therefore I suspect, there might be another variant of tuning besides the tuning of the demo unit that I reviewed, but I cannot confirm that because I never tried or measure the other variant of RE800 with the 7 kHz peak. 7 kHz treble peak is easily detectable and won’t go unnoticed. So the possibility of being mistaken about it is rather slim. My Sennheiser HD800 has 7 kHz treble peak, so I’m quite familiar with it. Although at this price level we expect a much more stringent and consistent quality control. Anyway, that is just my suspicion, and I might be wrong. And hopefully, the new RE800 with detachable cable will have consistent tuning and a more stringent quality control.

    You can read some of the discussion about the 7 kHz peak here:

    In general, I’m not a big fan of bright tonality tuning, so RE800 tuning as mentioned earlier, is not my cup of tea. But having said that it doesn’t mean that I never enjoyed RE800 or my other bright sounding IEMs. Bright IEMs tends to polarize towards a certain type of recordings, good on some and not so good on others. So I generally prefer all-rounder IEMs with more natural tuning. It does sound great with certain recordings such as a classical orchestra. But I prefer a more balanced tuning with fuller sounding midrange and bass. In this review, I also will try to review RE800 from the treble-head point of view, as I think it is a suitable IEM for treble-head. What I mean by treble-head is those who prefer bright, clear, airy, transparent sound with rather lean midrange and bass.

    My 15 years old son has developed an interest in audio as well, and he has been involved in church audio setup. So I let him tried RE800 to get his opinion on the sound quality. He has no idea what is Hifiman RE800 and how much it cost. So we can say that his opinion is unbiased. After about an hour, he came back to me with this:

    06 IMG_0005a.jpg

    He said, that is roughly the frequency response of the RE800 that he observed. My measurement instrument is not reliable for frequency region above 10 kHz, so only useful for comparison of measurement below 10 kHz. From what I hear I believe the RE800 frequency response above 10 kHz is quite extended, not rolled-off as shown in the FR graph below. While for frequency below 10 kHz, my son’s estimation from what he heard is not very far from the measurement result. I’m quite impressed, he has good ears.

    Being a relatively bright sounding IEM, RE800 handles treble and sibilant pretty well. Treble is smooth and nicely extended, and IMHO not the ear-piercing type of treble. Sibilant is well managed in the sense that it doesn't sound harsh or piercing. RE800 might not be the IEM of choice for those who allergic to sibilant, but treble-heads will most probably find the sibilant level is acceptable and still far from being annoying. Especially when paired with smooth sounding sources like my Geek Out 2A and Onkyo DP-X1, RE800 treble is golden.

    08 20170630_135855a.jpg

    Although RE800 bass is quick and has pretty good sub-bass extension. But bass punch lacks power and impact. I won't call the bass as anemic, but for me, it is not satisfying enough, especially when a potent bass punch is desirable. But for recordings that don't really demand punchy bass, such as classical music, RE800 bass sounds pretty good.

    Midrange is clear and transparent but sounds rather lean, not the full-bodied type of midrange. All my friends that have tested the RE800 mostly mentioned about the midrange as being lean sounding, sometimes too lean to their liking. Someone even said the midrange sounds hollow for his recordings. For me, although I agree that the midrange sounds lean and transparent, but not at the level that I would call hollow. Midrange probably rather too lean for vocal lovers, and rather too bright for some pop recordings, but most vocal audiophile recordings that I've tested with RE800 actually sounds fine to me, in the sense that I still enjoy them with RE800. But generally, I agree that vocal is not RE800's forte. Classical orchestra, chamber music, and general acoustic instrumental recordings are what RE800 will truly shine. Again, it is a matter of personal preferences, but that would be my general recommendation for RE800.

    Different ear tips might cause slight changes to the tonality as well. As you can see below, a generic large bore ear tips (as shown in the picture above) that I tested on RE800 actually sounds pretty good as it reduces the treble brightness slightly.

    09 Hifiman RE800 Stock Grey Eartips (Blue) & Generic Eartips (Yellow).png

    In summary, I perceived the sound quality of the demo unit of RE800 that I review as:
    Moderately bright, clear and transparent, sparkling yet smooth sounding treble, lean clear midrange, lean bass with good sub-bass extension, fast bass but lack of bass punch, good bass and treble extension, fast transient, excellent detail retrieval and instrument separation.

    10 P1390431.jpg

    Compared to DUNU DK-3001
    11 P1390442.jpg

    RE800 perceived as slightly brighter with leaner midrange and bass. DK-3001 is slightly more forward sounding, with a bit more emphasize on the upper midrange. Bass sounds fuller on DK-3001, with more powerful punch and slam. DK-3001 bass is really good, effortless without being overpowering. Midrange body also sounds fuller and much better with vocal. RE800 bass is actually pretty good as well, especially the sub bass extension, but midbass part lacks body and punch power, and the smooth and clear midrange might be to lean for most vocal lovers. The resolution, detail retrieval, clarity, and transparency level are more or less similar. As you might have guessed, in my opinion, DK-3001 is the winner with a more 'spot-on' well-balanced tuning.

    Compared to AK T8iE Mk2
    13 P1390440.jpg

    AK T8iE Mk2 is the only single dynamic driver IEM that I have, that I think worth to be compared to RE800. The sonic signature of AK T8iE Mk2 is quite the opposite of RE800 sonic signature. AK T8iE Mk2 sounds warmer with fuller and stronger bass, fuller sounding midrange and smoother treble. Treble sparkle on AK T8iE Mk2 is not as sparkling as the RE800, and the smoother character of AK T8iE Mk2 treble is more sibilant friendly. When switching from RE800 to MK T8iE Mk2, I do miss the nice treble sparkle of RE800. But when playing vocal, AK T8iE MkII immediately takes the crown. Although AK T8iE Mk2 may sound warmer, but generally it is not a 'very' warm sounding IEM. AK T8iE Mk2 has just the right amount of warmness to the sounds to make general Pop recordings sound more pleasurable, without sacrificing the overall clarity. For my personal preference, AK T8iE Mk2 tuning is more suitable for me.

    Build and Comfort
    In my opinion, overall build quality is pretty good. Besides that 3.5mm jack that I feel unnecessarily too big for this small IEM, I don’t have any other complaint. I used it over the ear, therefore cable microphonic is not an issue. It is very small and comfortable to my ears.

    14 20170618_112305.jpg
    15 P1390426.jpg

    In the discussion thread, some mentioned about the bass tuning port position that might get blocked unintentionally and caused a very high increased of the bass level, causing inconsistent sound quality. I think it is a valid concern even though I never experienced it myself. I guess placing the bass tuning port on the opposite side of the barrel might be a safer option.

    16 P1390424.jpg
    17 P1390427.jpg 18 P1390428.jpg

    Now the $699 question. Is it $699 good? Quite subjective, and not easy to answer that question. For me personally, the answer is no. Simply because I’m not a treble-head. But those who enjoy emphasized clarity and transparency might say yes. I really like the small size and the comfortable shape, but I prefer a fuller sounding midrange and bass. RE800 performs really well on certain area, but the tuning might not suits everyone.

    HiFiMan RE800: Going for the Gold
    Written by B9Scrambler
    Published Aug 2, 2017
    Pros - Vibrant, detailed signature - Ergonomic shape - Quality Materials
    Cons - Fit and finish - Lack of adequate strain relief - Cable weight
    Greetings Head-fi!

    HiFiMan was founded in New York in 2005 by Dr. Fang Bian, at that point under the name Head Direct. Over the last decade the brand has grown and their lineup expanded with numerous models of headphones, earphones, media players, and more, spread across a vast swath of price points. 2017 has seen the release of some pretty impressive new top tier products.

    Today we are going to be checking out one these new products; the 9.2mm, dynamic driver based RE800. This is a compact in-ear monitor which advances and refines the physical design of the popular RE400 and RE600, with the inclusion of some neat new driver tech. Are they any good? Yes, yes they are, so let's look at why.


    I would like to thank Mark with HiFiMan for sending over the RE800, along with a few other goodies, for the purposes of review. I'm not entirely clear yet on whether this gear needs to go back to HiFiMan after the reviews are up. The thoughts within this review are mine and mine alone, and do not represent HiFiMan or any other entity. There is no financial incentive for writing this review.

    At the time of this writing, the RE800 retailed for 699 USD: http://store.hifiman.com/index.php/re-800.html

    I'm a 30 year old professional working for what is currently the largest luxury hotel chain on the planet. I have a background in Psychology which probably explains my somewhat dry writing style. My entry into the world of portable audio was due primarily to a lack of space for a full-sized stereo system during my university years, and truly began with the venerable JVC HA-FXT90. After reading pretty much the entirety of IjokerI's multi-earphone review thread, reviews from other established writers, and thus being greatly inspired, I took a chance and started writing my own.

    Fast forward a couple years and I'm thankful to have had the opportunity to write about products for wonderful companies like HiFiMan, RHA, Accutone, ADVANCED, NarMoo, Mixcder, Brainwavz, Meze, and many more. I don't do it for money or free stuff, but because this is my hobby and I enjoy it. If my reviews can help guide someone to a product that makes them happy, I'll consider that a job well done and payment enough.

    Gear used for testing was a Shanling M1, HiFiMan MegaMini, and my TEAC HA-501 headphone amp. I listen primarily to various EDM sub-genres (liquid drum and bass, breakbeat, drumstep, etc.), hip hop, and classic rock. While I enjoy a variety of signatures I generally lean towards slightly warm with elevated treble and sub-bass, an even mid-range response, and reduced mid-bass. Lately I've been enjoying more mellow and relaxed products with a bass tilt. Two of my favorite in-ears, the Echobox Finder X1 with grey filters installed and the Fischer Audio Dubliz Enhanced are good examples of my preferred signatures.

    Packaging and Accessories:

    I have to admit that I was pretty excited to dive in and see what the RE800 was all about after catching my first glimpse of the packaging. The exterior sleeve contains a close up of the RE800 with a honeycomb pattern in the background. Up in the top right hand corner is a sticker highlighting that this is the 24k Gold Edition, "electroplated with a fine 24k gold finish". Cool. The rear of the sleeve has come contact info for HiFiMan, their supported social media platforms, and some basic specifications.

    Sliding off the sheath means you're getting to the interesting parts. It reveals a large jewelry box sized case on which the HiFiMan logo is printed along with "Innovating the Art of Listening" and the model number: RE800.

    Flipping open the steel latch and lifting the lid reveals a swath of deep black, felt-like material coating a thick, dense foam displaying the RE800's earpieces and the included hard, clam-shell carrying case. Lifting out the foam sheet you find some documentation and those accessories not being held in the clam-shell case. Overall you get:

    - RE800 earphones

    - full-size display case

    - clam-shell portable case

    - 1 pair Comply T400 Large

    - 1 pair Comply T400 Medium

    - 1 pair grey bi-flange silicone tips (small bore)

    - 1 pair black bi-flange silicone tips (medium bore)

    - 1 pair black single flange silicone tips (wide bore)

    - 2 pair tri-flange silicone tips (medium/large)

    - 1 pair of stiff, silicone ear guides

    - warranty card

    - social media info card

    - soft cover Owner's Guide

    I have to give special acclaim to the Owner's Guide which is less manual, and more small coffee table book. The quality is fantastic with each page made from a thick, durable paper that shames the packaging many earphones come in. It starts with a message from HiFiMan's Founder and CEO, Dr. Fang Bian and proceeds to explain the technology behind the unique Topology Diaphragm used in the RE800, materials used for the housings and cable, and how to properly wear and maintain the RE800. It's a fairly basic but interesting read and a welcome inclusion.

    Overall I am pleased with the RE800's unboxing experience. The accessory kit admittedly feels a bit lacking, particularly the clam-shell case which you can pick up on AliExpress for less than a dollar, but there should be enough variety in the included tip set to find something that works for you. If not, someone who is in the market for this earphone probably already has a slew of 'favorite' tips to choose from instead.

    DSC01594.JPG DSC01599.JPG DSC01608.JPG
    Design, Build, Comfort, and Isolation:

    The RE800's ear piece design is basic, understated, and to my eyes quite attractive in it's simplicity. The matte gold plating is subtle enough to avoid catching the attention of those around you and doesn't look gaudy as one might expect when out of your ears and on display. While there isn't much going on with the design at first glance, a closer look reveals a slight flare at the rear of the housing which helps with gripping the ear pieces. The soft edges that make up the curves of the earpiece add some extra dimension to what would otherwise be a mostly featureless design.

    The materials selected for the RE800 are certainly quite nice. Gold-plated brass housings help give the RE800 the tonal properties HiFiMan was looking for. The Cystaline-copper, silver coated cable was selected for "its performance characteristics and notably its low cable capacitance..." which according to HiFiMan benefited the RE800's high frequency performance. Since I have no way of comparing the various cables that were in consideration, I'll take their word for it because I quite enjoy the RE800's vibrant treble presentation. The y-split and chin slider (thank you!) also look to be gold-plated, but I can't tell if HiFiMan used brass down there too. It's definitely metal though. The 90 degree angled jack is all-metal, gold-plated as well, and very chunky. Since I'm a blaspheming scrub I tried the RE800 with my smartphone. I found that the case didn't get in the way of the thick jack due to an extra 4mm of metal that gives the upper portion of the jack plenty of leeway.

    Once we start looking at build quality, my enthusiasm begins to wane. It's not that the RE800 is poorly built, far from it, but at the price I expected more. The two constituent parts that make up each ear piece have a clear seam separating them. On the right ear piece the coloring isn't consistent with the ear facing section being darker. This contrast isn't overly visible with the ear tip on, but remove it and it's quite obvious. It's not a major issue since it's purely cosmetic, but at 699 USD I would expect this to be flawless.

    DSC01611.JPG DSC01612.JPG DSC01613.JPG

    I also have mixed feelings about the cable, those cable noise certainly isn't one of them. Below the y-split it is thick and feels quite dense. Bends from being wrapped up remain after weeks of use, though it's not horrible and they've been slowly lessening, though they're still there. Above the y-split the cable is wonderfully flexible and all bends are gone. The offset is that it thins out significantly. This wouldn't be so bad if the cable was properly relieved at the ear pieces, y-split, and to a lesser extent at the beefy 90 degree angled jack (which seems to be self serviceable). This is being somewhat addressed by a revised version of the RE800 with a removable, MMCX terminated cable. Still, I would like to see HiFiMan keep the fixed cable version alive and update it with proper strain relief. It's a nice cable, it just needs some support.

    Another reason I think it needs the extra support afforded by proper strain relief is because it's a fairly heavy cable. This also results in cable down wear being less comfortable than I know it should be. The RE800 is tiny, ergonomically shaped, and the ear pieces themselves weigh very little. When worn cable down the weight tugs at the ear pieces and while it's not enough to pull them out completely, it gets obnoxious very quickly when I'm mobile. When worn cable up the comfort levels are high and I can use them pretty much indefinitely without fatigue or discomfort.

    When it comes to blocking out your environment, the RE800 is about what I was expecting; average. It's a ported dynamic driver earphone with a fairly shallow fit. I can hear myself type, the desk fan behind me, my work computer's fan screaming away to my right, trucks cruising outside, etc. It's all muted, but I can still hear it.

    Overall I think it's a beautifully designed and very comfortable earphone made from quality materials, but one that needs a bit more attention paid to the finer details.

    I personally quite enjoy the two stock bi-flange options. I'm not entirely sure what the differences are between the two, but I found myself leaning towards the black set as they seemed to seal better. My review was conducted based on how the RE800 paired with the stock bi-flange options. Some other tips I tried were;

    Comply T400 medium - If you are treble sensitive toss these on. They do a good job of sucking up any excess top end while filling out the low end. I didn't notice much effect on the mid-range. If I didn't enjoy the stock bi-flange tips so much, these would be my go-to.

    JVC medium from FXT90 - Opened sound stage even further but attenuated treble to an uncomfortable extent while making the RE800 sound somewhat loose and splashy.

    Ultimate Ears medium from UE600 - Similar experience to JVC's tips but with greater treble control and lessened emphasis.

    KZ 'Starline' medium - They provided the same sound as the stock bi-flange option, but via a longer tip. If you find the stock tips too short and don't want to resort to the tri-flange, these might be worth a shot. Only downfall was decreased comfort worn cable down. The extra length made the tugging of the cable more prominent.

    Dunu Heir-style medium single flange - Best of the 3rd party bunch. The extra shallow fit helped take in some of the cable weight without affecting the stock signature much, if at all.

    Havi Sennheiser-style dual flange - Normally one of my go-to tips, yet a very bad choice for the RE800. Way too much and very splashy treble.

    DSC01616.JPG DSC01620.JPG DSC01627.JPG

    I'm a bit of a sucker for the application of unique technology. In the case of the RE800 and it's flagship sibling the RE2000, that technology is HiFiMan's "Topology Diaphragm". According to the included documentation, a special nano-coating is applied to the diaphragm. By adjusting the layout, thickness, pattern, etc. they can achieve their desired tune. What I hear from the RE800 is relative neutrality in terms of mid-range and bass presence, with a nice uptick in the treble regions to give them some extra pizzazz.

    As someone who enjoys boosted treble, the RE800's presentation was quite enjoyable. Other reviews have noted a sharp peak in the 7k region which can cause fatigue if overdone, such as on the RHA CL1 Ceramic which re-calibrated my definition of "bright". I thought it was a fun earphone, but for brief periods only. Thankfully, with the RE800 I did not find this peak a tiring affair. It instead offered a slightly thin, very honed, airy, sparkly sound, not entirely unlike the treble tuning JVC applies to their micro-driver units. This also meant that it wasn't an entirely natural presentation with cymbals attacking a little too aggressively, though I though the decay time seemed about right. This tuning seemed most effective at the low volumes at which I typically listen; anywhere from 2-5 out of 32 (track and location dependent) through HiFiMan's MegaMini for example. Only when upping the volume considerably did it start to get uncomfortable and cause fatigue, but to my ears this is the case with most earphones.

    The RE800's mid-range is probably my favorite aspect of their signature, coming across quite natural sounding and exceptionall well-textured and detailed to my ears. Running through some great albums like Supertramp's 'Crime of the Century', Elton's John's 'Golden Yellow Brick Road', and Massive Attack's 'Mezzanine' were invigorating experiences. Leading into the upper mids the lean qualities of the treble were retained, thickening up as you shifted down into the lower mids. It's not entirely unlike how the mid-range is handled on my Accutone Pisces BA hybrid, though with greater subtlety and coherence.

    The RE800's bass seems tuned to follow the track's agenda, not it's own. If the track has bass in a supporting role, that's where it stays. If a deep bass line leads the track, such as on Massive Attack's 'Angel', the RE800 will portray it that way. Add to that some authoritative mid-bass punch with a quick attack and decay and the RE800 can quickly draw you into your music as you re-explore familiar tracks. It's a very convincing presentation that really helps with immersing myself into my music when I simply want to sit and listen.

    This earphone's expansive sound stage also helps with this immersion factor. My live recorded King Crimson tracks sound larger and more open than I'm used to, exacerbated by the RE800's slightly slender note presentation and excellent separation. The amount of detail this earphone pulls out of the track is pretty intense as well, making tracks like 'Easy Money' a blast. Using the RE800 for gaming is a killer experience, handily easily besting some of my favorite (though much less expensive) in-ears that I routinely use for this purpose, those being the Brainwavz B100 and Fischer Audio Dubliz Enhanced. The accuracy of imaging and layering with the RE800 is uncanny. As long as the sound design permits it, minute changes in direction are quite easily picked up.

    Overall I found the RE800 to be a very impressive listen. I can certainly see some finding the combination of treble energy and extreme detail a little fatiguing, but for my preferences I wouldn't have it any other way.

    Final Thoughts:

    When it comes down to it, I think the RE800 is a fantastic earphone. It's made from quality materials, the design is beautiful, and it's small and comfortable. It has an exceptionally detailed and vivid presentation that to my ears manages to avoid being uncomfortably bright or fatiguing. It's also an earphone that worked well with nearly anything I tossed it's way.

    It's sound and design are top notch, though fit and finish could see improvements. The poorly relieved and slightly heavy cable is also something to watch when considering raw longevity, but that's almost a moot concern since an MMCX equipped version is on the way to remedy this.

    While earphones in this price range are still somewhat alien to me, of those I have had the opportunity to spend a significant amount of time with the RE800 and it's vibrant sound clearly stands out and leaves a lingering, positive impression. I'm thankful to have heard and experienced it.

    Thanks for reading!

    Bright, Clear with a lot to like

    Pros - Clarity, coherency, soundstage, comfort
    Cons - Potentially troubling treble peak
    Firstly I would like to thank Hifiman for this sample, I always try to write honest reviews. These have had well over 100hrs of burn-in, in my opinion I have heard small changes and recommend you burn them in fully.

    Gear Used: Audio Opus #2 / HiFiMan MegeMini > RE800


    Packaging, Build Quality and Accessories:
    The RE800 come in a luxury box, the box has an outer sleeve that says the model name, with a picture and basic specs on the back. Take the sleeve off and you have a wooden box that has a laminate coating on it, with a metal plate with the brand and model number on it. The box has a metal latch and metal hinges, once you open it you will find the accessories and the IEM’s held in a foam inlay. Underneath the main tray you will find additional tips and also an owner’s book which is a very elegant paperback book. The packaging is superb and the un-boxing experience is first class, fitting for the price.


    The metal housing of the RE800 is tiny and very well finished; the cable is thick below the y-split but maybe a little thin above it. The cable on my pair is fixed, but HiFiMan have brought out a revised version with a detachable MMCX cable. Strain relief is mainly good but is lacking on the entry to the housing, hopefull this is fixed with the detachable cabled version. I think these are well built and the housing definitely feels like a quality IEM.

    The RE800 comes with quite a few accessories, you get some ear guides for wearing them with the cable routed behind the ear, 2 different types of single flange tips, and triple flange tips in M and L. You also get 2 pairs of Comply foam tips and a clamshell carry case. For the price I think more tips could have been included, and a metal case like the one of the RE2000 would be nice over a normal clamshell case.


    Comfort, Isolation, Driver flex and Cable noise:
    The RE800 are one of the most comfortable IEM’s around, the tiny housing combined with the light weight means once inserted they are comfortable for hours. I found them most comfortable with the cable routed behind my ear.

    Isolation is good, they are vented so won’t isolate as much as a fully sealed IEM but for general use and some commuting they would be perfectly fine.

    Driver flex is present occasionally, but only upon initial insertion and is not bad.

    Cable noise is minimal when worn cable straight down, and never present when worn with the cable over the ear.


    Based on the sound with stock grey bi-flange tips, split into the usual categories with a conclusion at the end:

    Lows: The lows on these are similar in some ways to the RE2000, but a little leaner, they come out when called for yet stay in the background when not needed. The extend right down to the sub-bass with ease and linearity, stick on some acoustic and the body is there, some heavy rock and they keep up with ease, then put on some hip-hop/rap and be prepared to hear/feel the sub-bass come out to play. The lows are enjoyable with all genres, and are never bloated; they never encroach on the midrange.

    Mids: The lows don’t bleed into the mids, keeping them crisp and detailed without any extra body. The do come across with a slightly cold tonality, but has excellent separation and speed. There is an emphasis on the upper mids giving female vocals a bit more presence than males, but there is also a tiny bit of sibilance. The mids are well balanced with the rest of the sound of the RE800, never becoming strident or shouty.

    Highs: First off, let’s get the bad out of the way, there is a bit of a peak at 7 kHz that can cause fatigue for some and also gives cymbals a bit of a metallic tone upon initial impact. But with that out of the way, some tip rolling can help tame this, as could a touch EQ if you find the peak to be problematic, which I do not. I actually like that these have a nicely extended high frequency response, with plenty of detail and air. You will never lose track of the treble frequencies, but I still don’t find them sharp or overly bright (your mileage may vary).

    The soundstage on the RE800 is realistic and track dependent, it is fairly intimate but everything is well separated with about equal width and height.
    Instrument separation is superb with excellent transient response.


    Conclusion: The RE800 is fast, exciting and borderline bright to some ears and with some tips. There is a flaw, which is the peak, but this can be remedied somewhat with tips to those that are sensitive to treble. The other downside has actually been fixed, HiFiMan have now revised the RE800 to now come with a detachable cable that uses a MMCX cable.

    Overall the RE800 is an excellent monitor that does well with a multitude of genres, there is fantastic coherency that you just don’t quite get with multi BA designs, full bodied bass when needed, a midrange packed full of micro detail and some shimmering and well extended treble. If you crave details, crisp sound and a convincing soundstage these are worth a listen. I have found these play very well with a lot of the faster rock music I listen to.

    Sound Perfection Rating: 8.5/10 (some won’t like the treble peak, but there’s a lot to like in these)

    Hifiman RE800

    Pros - Great soundstage, great imaging
    Cons - Price and the cable noise
    I would like to thank Hifiman and AV One for this opportunity to review Hifiman"s latest Iems called the RE800.
    I love the unboxing experience as the box and presentation feels premium and the unboxing begins. I do feel like its a jewellery box at first glance with it black background and it focus my attention to the Iems and its carrying case.
    Inside the box, you will the Iems, user guide which explains the unit itself and the history of Hifiman and the paper documents. In the carrying case, you will find two sets of comply foam tips, a pair of ear guides for those who prefer to wear over-the-ear style. Lastly the various silicon tips which are the standard small, medium and large plus it comes with some flange tips. However, the unit itself has been attached with a pair of grey silicone tips which to me is just nice for my comfort and seal.
    The Iems are a small unit and it houses a single dynamic driver. The outer housing is stunning to look at with the 24K gold plated brass housing and same goes for it thin Y-splitter. The cable is fixed so its not detachable and terminates in a right angled standard 3.5mm Oyaide plug.
    I generally use the unit on the go and the only thing that caught my attention was the cable noise while walking as I do travel to work. The cable noise is very noticeable as it hits my body when I put them on with or without music played.
    Out of the box, the RE800 sounded thin, it has a lot of sparkles in the highs, the bass impact was noticeable but at times not really there and the mids sounded grainy. Therefore, through burning in the unit for a number of weeks. I will explain the sound further in the next section.
    First, I would like to to explain about the lows. It gets a whole lot better as it gets more punchier when it needs to be, a more cleaner punch and with a noticeable sub bass. I am able to get goof low ends that does not interrupt the mids and highs. Furthermore, it is able to deliver a much fuller sound and warmth which I enjoyed it very much.
    Next will be the mid-range. They eventually will get much smoother over time and its clean sounding and when the vocals come, its positioned slightly forward. I enjoyed the mids from some tracks that I played like from Enya and ACDC.
    Third, the highs and what a a great improvement. They get sweeter and less sparkles here and there plus the highs do not roll off too quick. This is because I like to listen to genres like Rock and Roll, Classical and Opera. This is where the highs are more important because it has to be just right like the cymbals and not too much of the hissing sounds that I get a lot initially.
    Lastly will be the soundstage, its wide and always is. I do have a nice presentation when listening and has an amount of airiness to it. I do like that the drivers are quick for its frequency range.
    After explaining much, I will summarize what I have written so far. Though the RE800 is not the flagship of Hifiman, it sounds great for it category. Its a wide range and wide soundstage Iems but it leans toward a bright sounding signature.

    Thank you.

    HiFiMan RE800
    Written by Arysyn
    Published Jul 26, 2017
    Pros - Sound & Staging : Bass tight and near-neutral, Mids clear and neutral, Treble excellent all around with plenty of detail and space. Mostly intimate 3d-like sound
    Design & Fit : One of the very finest and best on the market
    Cons - While near-perfect to my preference, it would match my ideal sound signature with slightly less Bass quantity, and Vocals a bit more forward.
    Hello to everyone reading this, which is my first review posted here on Head-Fi. This is my overview of the RE800 by HiFiMan.

    To begin, I am going to give a bit of a disclaimer of sorts about my review style. From my experience reading and writing reviews, there are various ways in which a review can be written. The more common way I've seen, is where the reviewer describes the subject of the review from the perspective of trying to help you, the reader, in deciding whether or not to further explore the subject being reviewed in such ways that include the possibility of trying or buying that which is being reviewed.

    Of course I'd like for my reviews to help readers make those considerations more positively and productively. Although, sometimes reviews can be written in a way where it appears the reviewer is trying either to promote or discourage the sales of the subject being reviewed, whether or not that was the reviewer's intention.

    While the focus of a review still should be on the subject itself, I believe in order to avoid any negative connotations connecting myself to a particular subject I'm reviewing, I will write reviews in a style of my personal experience with the subject of my review as if I'm being interviewed about it, where my experiences with the topic are at least almost as important as the focus on the subject itself.

    Despite my technical reliance on audio frequency response graphs, which I utilize in understanding the sound signature output of a particular audio product, I believe that regardless of the technical attributes and the particular specifications of these audio products in delivering their sound signature output to every listener, there are a variety of various and varying variable interpretations of the very individual and unique perceptions from the resulting production that also deserves recognition when interpreting results regarding the sound signature output of any particular audio product.

    In writing my reviews and in reading comments from those who've read them, I will try to teach what I know, along with learning from others, particularly involving their connections to these personal audio products not only through the technical aspects of sound connectivity, but also from the sharing of our experiences brought on by the emotional connectedness to the music and delivered to us by the sources we choose to utilize for this very purpose. It is in that common bond we connect socially in our spiritual quest for that perfect sound, the very harmony which matches our deepest lows, our most enveloping and surrounding mids, and our heightened highs that delivers us to our sanctuary of sound, our audio utopia.

    In traveling on our journey to musical nirvana, there are plenty of insightful tools to help us reach that heavenly state of audio bliss. One of which is like a travel guide, audio frequency response graphs, which to us audio enthusiasts basically are scientific roadmaps to that wonderful soundscape we call our ideal sound signature. These are great tools to help us understand what our audio devices sound like. I am particularly dependant on these graphs to give me a clear description of a device's sound. Although as I mentioned earlier in this review, individual interpretations of each listener may differ, and the input they offer regarding their perceptions also are important to the understanding of audio output data.

    I happen to have recently had my very own audio frequency response graph designed for me by a graphic designer, to show an example of what my ideal sound signature is. I've already posted the graph in a few threads on the Head-Fi forum, but for the sake of this review, I'll display it again here.


    I'd say that pretty much describes my review stylings, including my own preferences. So now I'll begin discussing my impressions here about an audio product of Dynamic Driver - based iem earphones I believe produces a sound signature which somewhat closely resembles my own ideal sound signature preferences displayed on the audio frequency response graph, or at least it is one of the closest to doing so of all the Dynamic Driver - based iem earphones I've seen from the many audio frequency response graphs I've viewed online.

    The Dynamic Driver - based iem earphones I'm referring to, is the HiFiMan RE800. However, before I begin to describe my impressions of it, there is an audio frequency response graph of the RE800 displayed on the forum, which was produced by one of the Head-Fi Moderators, Brooko, of which I'm going to display here :


    While there are some differences between the RE800 and my ideal sound signature preferences, which are evident in the audio frequency response graphs displaying those differences, there also are some similarities. I will be describing them here throughout my review of the HiFiMan RE800.

    In regards to reviews concerning audio products, most of these reviews begin describing in detail everything visible regarding the product's design, fit, and the supplied accessories, along with displaying photographs relating to these details. Accompanying those photos, are images of other items that were brought alongside the main audio product. The important thing here to note regarding these aspects of the RE800, is that the build itself is made of a high-quality brass material housing, and it appears to be one of the best fitting iem earphones on the market.

    The product ought to fit very well in most ears, though isolation is highly dependent on the tip size. However, as is the case with almost any product purchase, the details regarding these issues ought to be researched thoroughly by the buyer in questioning the manufacturer and/or merchant about these details prior to purchase. No reviewer can completely describe the fit and feel of these audio products to the reader in absolute description to completion.

    My viewpoint of addressing accessories in a non-shopping product review, is that I believe such details are more appropriately suited for discussion in forum posts and in the reviews sections on merchant websites. I also believe the greater detail of these side offerings are best left to the manufacturer and the merchant to explain in their product's descriptions and purchasing information.

    I'm assuming that at least most viewers reading this review have already become aware of my ideal sound signature by looking at the audio frequency response graph I posted earlier in this review, which displays what my ideal sound signature essentially is. However, I'll also describe it in comparative words contrasting that of the sound signature produced by the RE800.

    In conducting my impression study for this review, I've listened to my song choices I hear when first trying a new audio product. These are the following tracks :

    Curtains (Myst4 Revelation version) by Peter Gabriel
    Veni Redemptor Gentium by Paul Schwartz
    Turning to Peace by Paul Schwartz
    Forever by Schiller
    Let Me Love You by Schiller
    Rivers of Belief by Enigma
    Return to Innocence by Enigma
    Dreammaker by Thomas Bergersen
    Merchant Prince by Thomas Bergersen
    Moment of Peace by Gregorian

    There are other tracks I normally listen to when first trying a new audio product, along with those I listed. However, I haven't found the time to do so yet.

    The main dac/amp source I'm using for the RE800, is the Meridian Explorer2, which hopefully I'll be reviewing sometime soon. I've also listened to the RE800 through the Turtle Beach Audio Advantage Roadie and the Zorloo Zuperdac. The differences in how the sources affected the sound signature of the RE800 were noticeable. From my estimation of the sources I've used regarding which source is producing the most similar sound signature in contrast with what the Meridian Explorer2 produces, is the Turtle Beach Audio Advantage Roadie, which when used with the RE800, increased the Bass by a 2dB difference between neutral, about half the measurement shown by the audio frequency response graph produced by Brooko. while bringing the Mids and Vocals to about neutral. The Treble sounds slightly less detailed than the Treble produced by the Meridian Explorer2. The Zorloo Zuperdac increased the Bass by double the amount in contrast with the Bass produced by the Turtle Beach Audio Advantage Roadie, or similar to the results shown by the audio frequency response graph produced by Brooko. The Treble sounds much less detailed than the Treble produced by the Meridian Explorer2. That describes how the RE800 sounds when listened through the sources I utilized.

    Now, I'll overview the differences between listening to the RE800 through the Meridian Explorer2 in contrast with the audio frequency graph showing my ideal sound signature.

    Mine (Bass region) : There is a line starting at the very beginning, which is at the 0Hz point, going upwards a 30dB increase to neutral, at the 50Hz point, which is near the middle of the Low-Bass region. From here at the 50Hz point, there is a neutral line to the 250Hz point. This is at the end of the entire Bass region.

    ME2/RE800 (Bass region) : There appears to be a very small amount more quantity in the Sub-Bass region than in my preference. The neutrality starts earlier in the Low-Bass region than in my preference. A neutral Bass overall, though because it begins earlier in the Bass region than in my preference, it provides a bit more Bass quantity than what I prefer. Although, the Bass quality is very good.

    Mine (Mids region) : From here at the 250Hz point, which is at the beginning of the Low-Mids region, there is a line going diagonally upwards a 5dB increase to the 500Hz point. This is at the end of the Low-Mids region, and at the beginning of the Mid-Mids region. From here at the 500Hz point, there is a neutral line to the 1KHz point. This is at the end of the Mid-Mids region, and at the beginning of the High-Mids region. From here at the 1KHz point, there is a line going diagonally upwards a 5dB increase to the 2KHz point. This is at the end of the entire Mids region.

    ME2/RE800 (Mids region) : Mostly neutral. Very rarely becomes recessed at all. However, my preference is for Vocals to be more forward. Although, the quality in keeping the Bass region separated from the Mids region is very good.

    Mine (Treble region) : From here at the 2KHz point, which is at the beginning of the Low-Treble region, there is a neutral line to the 10KHz point. This is at the beginning of the High-Treble region, where the audio frequency usually begins its decrease downwards on the audio frequency response graphs. Mine does too, but in a slow, even pattern, until the end.

    In comparing the ME2/RE800 Treble to my Treble preference, both are great. My preference would be a slightly higher Treble than the Mids of my preference, yet would remain flat in the Treble, without any peaks or dips. Although, I haven't yet heard any negative side effects from the Treble on the ME2/RE800 configuration as it is.

    My preference basically has the Bass at a low/neutral level, lower Mids on a slow incline upwards, so as to not allow muddiness into the sound, flattening in the middle of the Mids across that region for even, forward Vocals, then another slow incline upwards on the higher Mids for a fair buildup in clarity towards the Treble, which remains flat throughout, until towards the end.

    The ME2/RE800 has a smaller, opera house staging, rather than an arena staging. More intimate, though certainly larger than in a studio setting.

    The ME2/RE800 combination is great, regardless of my preferential differences. Despite that it doesn't completely match my preference, it gets close enough in the areas that really matter. Although, the other sources used with the RE800 did make me think more negatively towards the RE800 for the fact there was too much Bass, and not enough forwardness in the Vocals. Still, with the ME2 by its side and connected as its source, the RE800 is as great as I think it can be.

    Pros - High resolution even 1 DD, Rich bass, Silky treble, Comfortable fit, Luxury appearance
    Cons - Passive mid-range(depend on device), Poor carrying case

    Hifiman Electronics is an audio manufacturer established in New York, USA in 2007 and is one of the few places that can produce headphones with magnetic planer driver. It is also introduced in "TIMES" magazine and has a high level of technology that earns good reputations from famous audio commentators. Hifiman, has focused on producing headphones for the past a decade, now challenges in-ear headphone market, which has been showing great growth in recent years.

    Specification of ‘RE800’ is pretty gorgeous. Brass housings are treated with 24K pure gold and new diaphragm technology called 'Topology diaphragm' is implanted on ‘RE800’. The 'topology diaphragm' is nano-coated on the surface of diaphragms, which can suppress distortion more than usual dynamics-drivers, while still providing a wider dynamic-range and headroom than amateur-balanced drivers. At the same time, it is possible to output the expression of the sound more uniformly.



    The enclosures of both housings are made smaller than regular earphones in the same price range. Thanks to the reason, ‘RE800’ is possible to wear with over-ear-way too, so that people who have even small or big ear-canals use it more easily. Nozzles are the most common size (4 mm diameter), and the entrances are tightly covered with wire mesh. The single ducts beneath it reduced vibration of the diaphragm (Cracking sound when plug into canals) and air pressure in the ears.

    The cable is covered with a soft black cloth over silver-plated wires, and seems really simple likes ordinary earphone cables. The Y split and the cable slider are also plated with pure gold over brass materials, with brand and product model names engraved back and forth. The 3.5mm stereo input plug is made in a long and heavy-weighted with 'L' shape. There is some clearance in front of the plug, so no problem when using together with a smartphone or a portable audio device with thick cases.


    In particular, a single full-range silicon ear-tips are unique in that those are a single mass and has a layer like a double flange silicone ear-tips. The contained ear-guides provide good grip to prevent the ‘RE800’ from flowing down when mounted with over-ear way. The pouch has a pocket inside. However, it is still unfortunate that earphone is not completely protected against scratches or damage.

    The "RE800" showcases emphasis on harmonic of the treble and bass. The presentation of sounds clearly is located from the center of the listener's head and width of soundstage is not opened than the shoulders. Even though midrange tends to be laid back a little because of the emphasized high and low frequency, there was no suppression or obtuse feeling due to the clear stage image.

    The bass particles are as micro-powder like flour and the roll-off response is linear and slowly decays. This feature delights listeners by explosion of intense bass, which sounds among even a lot of string-instruments in the orchestra as like as dust-explosion-characteristic.

    Thanks to the bass that resonates reliably without excessive distortion, even if the low-bass is emphasized, it does not give the listener fatigue. The smooth texture of the bass and natural expression is to be of great benefit in expressing the sounds of analog instruments, but in electronic music, bass instruments possibly tend to overlap one another.
    The midrange is warm and reverberant, allowing you to feel clear harmonic texture of vocals, pianos and classical guitars, and is heard one step laid back giving calm and clear tendency. The reverberation is evenly distributed to the upper and lower middles, and catches the sharp expression of female vocals as well as male’s.


    The "RE800" has sheen, airy, and textured sound-signature on treble so that can play sound-sources with fast and rhythmical string instruments without any awkwardness. The lower treble has reverberation with moisture texture, and expresses well a feeling of emptiness after a violin string ringing well. Also, vivid and lively in female vocals as well.

    Depending on the enclosed ear-tips, it can be transformed into four different sound-signature. The Bi-flange silicone ear-tips reduce the amount of mid-bass, gives you a more-sheen harmonic tone at treble, and the full-range silicon ear-tips pull the middle forward and inflate upper-bass. The Tri-flange ear-tips give flattened sound tone on middle and treble, and more condensed sharper bass. The memory foam ear-tips suppress the representation of the middle and treble, also emphasize the mid bass, making the overall sound-signature softer.

    It has a resistance value of 60 ohms and requires high volume in light output devices such as smart phones. If you do not secure the proper output, occurs sibilance at the upper midrange easily, so that recommend matching with devices having a stable output volume level. "RE800" is recommended to use with DAP called ‘Megamini’ makes the passive midrange more clear and accurate, and gives the bass more natural and hitting.



    "RE800" not only shows high-quality appearance with pure gold plating, but also a natural bass and treble performance while showing a resolution comparable to that of multiple BA with a single dynamic driver. Small size and simple design have shown the benefits of comfort and practicality. If interested in in-ear monitor with luxury look and natural sound performance, "RE800" will be a good choice.


    Hello, I am a Head-fi product reviewer named 'Bigheadfiler' in South Korea. This review may not be perfect because it is my 6th English translation. I appreciate your understanding. Thank you.

    The RE800 was offered by ‘Hifiman Electronics’. The content of the review has been written without any restriction because the authors' freedom is respected.
