    Balance & Quality in every aspect!

    About Hifiman:

    Hifiman was founded by Dr. Fang in New York - USA and is one of the most well-known personal audio companies in the audiophile word.

    Hifiman has a wide variety of Hi-Fi, Reference and Premium class products like Portable Audio Players, Planar Magnetic Headphones, Desktop Amplifiers and Earphones/In-Ear Monitors such as the Hifiman RE2000 Silver, which belongs to the Reference Series of Earphones and that I will now review for you.


    About me: www.moonstarreviews.net


    I would like to thank Hifiman for providing me the RE2000 Silver for review purposes. I am not affiliated with Hifiman and/or any third person beyond this review and all these words reflect my true, unaltered opinions about the product.


    The Hifiman RE2000 Silver is 500,00 USD cheaper than the Gold Version and is available for 1500,00 USD.

    You can purchase the RE2000 under de following link; http://hifiman.com/products/detail/291

    Package and Accessories:

    The Hifiman RE2000 Silver IEM is coming in a rectangular black box, which consists of two parts; the bottom box where you can find two smaller boxes (containing cable and other accessories) and the metal case, which is put in to a foam layer, and the top cover that is containing an image of the RE2000 Silver.

    Inside of the box are the following contents/accessories;

    • 1 pair x Hifiman RE2000 Silver Earphone Monitor
    • 2 pairs x Bi-Flange Silicone Ear Tips
    • 2 pairs x Triple Flange Ear Tips (in black color)
    • 2 pairs x Dual Flange Ear Tips (they are 3 different shapes)
    • 1 pcs x Metal Case
    • 1 pair x Ear Hook Cable Guides
    • 2 pairs x 2-pin adapters for building custom cables
    • 1 pcs x Print Material


    The Hifiman RE2000 Silver comes with lots of accessories from what I found the 2pin adapters for building your own custom cable, pretty interesting and as nice addition.

    Inside the box you can find also different type of silicone ear tips, such as Triple flange, Double Flange and Hifiman’s special Bi-Flange silicone ear tips.

    There is also a metal case with the Hifiman Branding on the top. The case is pretty solid that sports a rubber ring/gasket for extra isolation and a foam layer with the exact same shape of monitor shell, where you can put in your Hifiman R2000 Silver monitors.


    You can find also a pair of ear hooks (cable guides) and a catalog that is showing images and information’s about the RE2000 Silver.

    Technical Specifications:

    • Driver : 9.2mm Topology Diaphragm Dynamic Driver
    • Frequency Response : 5Hz-20 kHz
    • Impedance : 60ohm
    • Sensitivity : 103dB
    • Cable Material : Silver Coated, Crystal Copper Wire
    • Weight : 24g (cable included)

    Design & Build Quality:

    The Hifiman RE2000 Silver shares the unique design language like the RE2000 Gold version. The main difference is not only the color; the material used for the shell is now silver with an aluminum alloy instead of a gold plated brass material, which makes the Silver version also slightly lighter.


    On the front of the monitor housing is the sound nozzle, which is short in its size. This sound nozzle has a lip to hold the ear tips and sports a near fine woven metal grill to prevent the possible insertion of dust and earwax.


    Near the nozzle is a small vent to balance the pressure in the housing to avoid any unwanted driver flex.


    On the top of the monitor is a strain relief made of a hard plastic material which is in black color. The RE2000 Silver sports a 2pin female connector on this monitor which has the standard diameter of 0,78mm. There is a guide inside the plastic strain relief, which help to insert the 2pin male connector on the cable safely.


    The monitor shell has a smooth surface without any sharp edges that makes the RE2000 Silver comfortable to wear.


    The overall build quality is very robust and meets the expectations from an In-Ear Monitor in this price level.

    The Cable:

    The Hifiman RE2000 Silver has a detachable cable with 2pin male connectors that support the standard diameter of 0,78mm.

    The cable of the RE2000 is quite thick and is made of a silver plated crystalline copper wire, which is protected by a thick TPU coating.


    The 2pin connector has a black hard plastic housing that sports the L & R markings.


    This cable has a metal Y splitter and a chin slider, which sport the Hifiman branding and model description.


    The cable of the RE2000 Silver sports a 3.5mm 3 pole unbalanced (TRS) earphone jack which has a straight profile and is made of metal same as the housing.


    Comfort and Isolation:

    The size of the RE2000 Silver housing is not as big like the Astell&Kern Rosie or Angie and not that small like the RE800/RE400 or the Sennheiser ie800. I have medium sized ears and the RE2000 Silver has the ideal size for to wear it quite comfortable for hours.

    The Hifiman RE2000 is in my opinion suitable for long listening periods.

    When it comes to the isolation of the Hifiman RE2000 I can classify it as average, which makes it noise blocking performance enough to use it outdoors in relative noise environments such as train, bus or metro, etc.


    Some Features:

    The Topology Driver/Diaphragm:

    The “Topology Diaphragm” or “Topology Driver” refers to the diaphragm with a special Nano particle coating applied to its surface. The distribution of the coating has distinct geometric patterns. By varying the surface pattern, compound used, the thickness or geometric pattern sound wave formation can be manipulated to achieve the desired audio effect and control.

    The idea behind the new Topology Diaphragm was inspired by Dr Fang Bian's Ph.D. thesis that "different Nano materials have differing structures and each of those materials have its own properties".

    Therefore, by carefully controlling the diaphragm surface structure you can yield different results in acoustic performance to a degree previously unobtainable.



    The Hifiman RE2000 Silver has a rated impedance of 60ohm, which looks a bit high on paper, but I was able to drive it to quite loud volume levels with my Samsung Galaxy S9 mobile phone. But I can also confirm that the RE800 benefits from an external amplifier or DAC/AMP, which has improve the sound in a positive way, especially the overall refinement.

    The Sound:

    This review is written after a burn-in process of approx. 60 hours and I have used the stock bi-flange silicone ear tips.

    Sound Signature:

    The Hifiman RE2000 Silver is an In-Ear Monitor with a slightly V shaped sound signature, which shows a musical, transparent and somewhat warm midrange, fast and fairly deep bass response, soft tuned upper midrange and a treble that is energetic and with nice sparkle. All this features making the Hifiman RE2000 Silver to an and In-Ear Monitor with a pretty balanced, smooth and musical presentation.


    The Bass:

    a) Sub-Bass:

    The sub-bass of the RE2000 silver has a pretty good depth and shows an average force, spread and extension.

    The sub-bass depth is on good level and has a rumble that is not too high, nor too low. For example; the sub-bass in Massive Attack's “Angel” and Portishead’s “It Could Be Sweet” songs is on a sufficient level. The tonality of the sub-bass is a bit warm, is followable and shows good clarity.

    b) Bass and Mid Bass:

    The mid-bass presentation of the Hifiman RE2000 silver is not very close to the listener and is positioned in to the middle of the stage, which is avoiding problems such as hollowness and compression of the stage. The tonality of the mid-bass area is not very neutral and shows a hint of warmness. The mid-bass region of the RE2000 silver is fast, controlled and close to reference, while listening to many types of percussion instruments, drums or guitars which is pretty impressive for an In-Ear Monitor with a dynamic driver.

    The bass punch of the Hifiman RE2000 has a tuning that is moving between softness and a mildly hardness. The bass slam/punch is pretty noticeable which makes the RE2000 silver quite suitable for most genres. The bass quantity of the RE2000 silver is a bit less to categorize it as bass on a basshead level and can be considered as a little more than neutral.


    The Midrange:

    The midrange of the Hifiman RE2000 silver is slightly recessed due to the V shaped tuning and shows in general a musical and mildly warm presentation. The level of transparency and airiness is not the highest but above average.

    1. Vocals:

    a) Male Vocals:

    The overall tonality of the lower midrange pretty neutral that allows to hear male vocals in an unveiled and clear way. It doesn’t exist any negative situation such as a thinness, muddiness or harshness of the sound, while I have listened to male vocals. Some vocals such as Dave Gahan, Freddy Mercury, Kurt Cobain, Eric Clapton are presented in a clean, musical and slightly thick tonality that I have enjoyed.

    b) Female Vocals:

    The female vocal presentation of The Hifiman RE2000 silver is soft, a bit warm and quite musical and they are no negative situations such as sibilance of ear piercing type of harshness, which makes the RE2000 sliver ideal to listen for long periods. I've had some pleasant times with the RE2000 silver sensual and sweet female vocals. The transparency and airiness, while listening to female vocals is on good level,

    Female vocals with a thick tonality such as mezzo soprano singers like Edith Piaff are presented with a pretty natural detail and timber.

    2. Instruments:

    The instrument presentation of the Hifiman RE2000 silver is full bodied and shows a hint of warmness. It doesn’t have a highly analytical, dry and weak timber. It is existing a pretty neutral air between the instruments that helps for an airy and clean presentation.

    The fact that the instruments don’t play very close and distant to each other makes the RE2000 Silver well balanced and musical.

    The Hifiman RE2000 Silver is very successful in terms of instrument detail, clarity, separation and definition. Guitars sounding slightly warm, bassy and bright that makes its presentation quite musical, soft and fatigue free.

    Instruments such as pianos sounding soft and a bit bright, while listening to Chopin's Nocturne. Every bow traction sounds very clearly with the Hifiman RE2000 Silver while violas are played in both bass and midrange.

    Upper Midrange:

    The upper midrange presentation of the Hifiman RE2000 Silver sounds close to neutral and is mildly emphasized, soft and not overwhelming. The transition of the upper midrange is pretty controlled and soft, without any noticeable harshness or sibilance. The RE2000 Silver sounds fatigue free and musical due to the mildly emphasized upper midrange tuning.

    There detail level and technicality in this this area is above average and makes the RE2000 suitable for longer listening periods.


    The Treble:

    The lower treble area of the Hifiman RE2000 Silver sounds more quite pronounced after the softer tuned upper midrange, which makes the overall presentation airy and detailed.

    The brightness and great extension in the lower treble area gives the RE2000 an energetic and highly dynamic presentation. The lower treble area is more pronounced than those of the upper treble region that sound slightly less detailed.

    For example; instruments such as hi-hats in genres like metal music coming slightly from the background and are hitting clean and with a fairly thick tonality, without to extent too much

    Instruments such as crash cymbals have a very controlled decay and with a slightly less extension than perfect. The general treble quantity and force will good enough for most listener. I like the balance and control in this frequency region and didn’t experienced any treble harshness or fatigue while listening to pretty fast groups like Slayer, Havok or Trivium.

    You can listen with the Hifiman RE2000 Silver all kinds of metal music without to fear about the treble and this with a musical tonality.

    The Soundstage:

    The Hifiman RE2000 Silver has a suitable stage width for a realistic instrument placement with enough space between instruments and vocals. The RE2000 Silver is also able to place the instruments side by side horizontally with enough space and neutral air between them.

    The Hifiman RE2000 Silver shows a parallel performance of the depth to its width.
