Single BA Jomo in-ear with no crossover, no phase cancellation. Just powerful and coherent pure sound.

Jomo Haka

  • Limited by the physical size of driver, Balanced Armature technology were believed that cannot produce full spectrum of sound so that multiple drivers with electronics passive crossover and acoustic damping has to be used to create something with decent bass, smooth mid range and sharp high frequencies.

    We studied existing single BA driver IEMs in the market and the result was not very pleasant. We kept challenging ourselves to see what we can deliver by using the minimum number of driver and how we can make it better.

    Working closely with well-known Balanced Armature technology supplier, we were not satisfied with what they can provide off the shelf. We went one step further, to design new Balanced Armature driver with our own specification. Brainstorm and discussion meeting with the engineers, samples were made and tested over and over again. Multiple rounds of pre-production demo and peer critique with industry insiders. Haka is the result and answer of our hardworking.

    The Jomo Haka is a single balanced armature driver IEM available in Universal IEM (UIEM) or Custom IEM (CIEM) form. For the purpose of this review, we will be looking at the CIEM version of the Haka. The Haka comes in at S$599 and $499 for the base model of the CIEM and UIEM respectively. These IEMs are not cheap by any means so they’d better deliver in performance and build quality. But do they?

    The Haka comes in a minimalistic black box with the words “HAKA” and “In-Ear monitors” on the front. Very simple, but I really dig the design – it just screams professionalism.

    Open up the box and you will find a warranty card, an aluminum case to house your IEM and lastly, the IEM itself. Do note that you do not get ear tips for the CIEM version of the Haka as there is no need for those.


    The Haka is housed in a very well made glossy finished acrylic shell which I have no complaints about. The golden “Gloryrain” logo is precision laser engraved into the shell and looks absolutely stunning. The housing does have some heft to it and the build quality is really commendable.


    The stock wire that comes with the Haka is a 4-core Silver Plated Copper (SPC) wire which is really just decent. I am not saying that the cable is bad or of poor quality but it is unremarkable for the Haka’s price point. The cable is machine braided and the braiding is tight. The 3.5 mm jack is solid with a decent enough strain relief system and the connector terminates into a 0.78 mm connector on the other end.


    Comfort on the Jomo Haka CIEM is no doubt fantastic, considering it is, after all, a custom. The acrylic nozzle does not put excessive pressure on the inner ear and fits snug as a pug. There is, however, some heat build up after an extended listening period, but nothing too extreme or uncomfortable.


    Okay. The Haka IEM is tuned in favor of musicality as opposed to technicality. It takes on the U-shaped sound signature that leans towards the warmer side and takes on a smooth and relaxed tonality.

    The soundstage on the Haka is not particularly wide, due to the tight seal and heightened amount of body in the bass and lower mids. Do not expect “live-like” tracks representation. Instrumental separation is also just average and you do not get a distinct sense of separation between guitars and the percussion. Be advised that the soundstage and instrumental separation is by no means bad, it just hits slightly above its price range.

    Vocals take a nice mid-presentation while instruments take on a more frontal presentation. Once again, soundstage is not especially wide but is good enough for the price.


    In the Haka, there is more sub-bass body than mid-bass body. Bass extension is quite good and mid-bass leans towards the tighter side of the spectrum. Bass takes on a relaxed presentation but has a tinge of aggression to it. The bass profile on the Haka actually helps bring out warmth in the sound signature.

    As mentioned, the Haka carries a U-shaped sound signature which means that the mid profile will be slightly recessed or laid back. Male vocals are thick, especially in the lower frequencies while female vocals take on a leaner approach as compared to male vocals. The upper and lower-mids are more forward than the mids (the mid-mids if that makes sense). Overall, the mids are well detailed and is good for the price.

    The trebbies are just slightly rolled off such that it is not fatiguing to listen to for long sessions and can be considered laid back. Also, with the rolled off treble, the IEM leans toward being musical instead of analytical. This is not a bright sounding IEM y any means and may not have enough treble for some.

    I personally would have preferred slightly more treble emphasis to show more details, especially in the mids and upper-mids regions as that is where the prominent frequencies of acoustic music.

    The Haka uses a detachable cable, thus cable rolling is a possibility. I found that the Haka pairs well with “treble-forwarding” cables, namely SPC and silver cables.

    The Haka uses a BA driver and is quite sensitive and can be easily driven off a phone. In my testing, I have used an AAW Accessport driven off an iPhone 7+ and only had the volume turned to 4 out of the 16 steps.

    In conclusion, the Jomo Haka is a good value for money CIEM. The slightly laid-back treble is very easy to listen to for longer sessions. If you are looking for a stage or studio monitor, these CIEM is probably not for you due to its U-shaped sound signature and rolled off trebles. It definitely fits better than all the universal IEMs I have owned as the seal here is near perfect so noise isolation and comfort is settled.

    However, if you are interested in getting yourself an entry level custom, the Haka is a good place to start. I highly recommend you audition the Jomo Haka universal IEM to get a feel of how the CIEM version would sound like however.

    The Jomo Audio Haka is a single BA. I had to go back and check the specs and also message Joe of Jomo to triple check. To my ears it performed as a decent dynamic driver or multi BA IEM. Color me surprised.
    I did the usual exhaustive burn in of over 100 hours to please believers and non-believers (who don't care anyway).
    Listening was done with a variety of tips until I as usual settled on on go to tips for fit and comfort the JVC Spiral Dots.

    I used a variety of daps such as the iBasso DX200 (amp 1), Opus #2, Fiio X7ii, Opus#3 and Echobox Explorer, Opus #1 and 1S, Shozy Alien+, Shanling M3s and an ipod touch 6G to get a lay of the land of the average performance one could expect across a field of daps. In summary the usual suspects.

    The tracks used in testing were mainly FLAC 16/44 on shuffle to give my brain and ears the unexpected.

    I don`t really think about the price of an item much anymore when I receive it. I just get the mail, unboxing photos, a little listen and take some notes, then leave it on burn for the burn in brethren and also to lessen the possible new toy syndrome. it then joins the review queue and I pick up the item occasionally and listen and take notes then put it back into its place in the queue based on first come, first served (rarely broken). This also serves to get a better sense of the item even though I could probably pump out something fairly accurate in 48 hours or a week perhaps. But I could never be fully sure I had plumbed the possible depths and idiosyncrasies of the review item.
    Later when the item comes closer to its turn in the queue it joins my everyday carrying stock of daps, IEMs and next review items as I cross check with tips, cables, other earphones and daps etc to get a hopefully true and accurate sense of the items sound.
    Often lastly I set up the headphone switcher box and have several sessions where I volume check with a SPL meter and reconfirm my findings. It is a lengthy process.

    Some reviews write themselves due to the excellence of the item, the build or the sound overall is coherent and pleasurable regardless of my preferred sonic signature etc. others are more of a struggle due to the opposite of the above.

    The Jomo Audio Haka is one of the former.


    Armed with a Single BA and housed in a strong shell the Jomo Audio Haka stuns at first glance. It bears a resemblance to a shell design that has seen a popularity of late. Also having only one BA it is at the forefront of what I expect to be a mini wave of single BA earphones coming out (such as the Campfire Audio Comet).

    But I have digressed enough off topic, where the focus of this section should strictly be the sound and not my methodology although essentially they are intertwined. Some may be inthralled, most probably are thinking 'I skipped all the way to the sound section for this!?'.

    'Thats all folks!' I mean 'On with the show'

    The Jomo Audio Haka performs well at moderate levels and doesn't need a huge amount of volume to satisfy.
    I comes across as fairly even across the board, verging on a reference, linear signature with a decent tinge of mids to fill it out. female vocals are smooth, rounded and gorgeous.

    It is very coherent and well tuned as I expect after hearing and reviewing several Jomo Audio models.
    Treble is sweet and not over extended, reaches just far enough to open everything up without ending up sibilant. Companies seem to be on the ball generally when it comes to treble these days.
    Bass is present but not hard hitting as in a defining feature, it is strong but with a softness to it, a still lingering deep boom boom with enough speed to please.

    Sound stage is just above medium. Lots of height, vocals central within the skull slightly towards the forehead, medium width, slight depth.
    Instrument separation is good, the limited sound stage impacts upon this at times. But generally has enough air and a sense of space. a brighter dap alleviates this to some extent.

    Layering becomes improved as one goes up the chain of daps, although even at the low-fi end it still pleases.
    On some tracks it became a bit brittle as the volume was pushed too far (beyond usual comfort levels), whereas on other tracks they were fine - so perhaps this was more the recordings themselves rather than the earphones I would surmise. But is one BA and not a DD.
    The Jomo Audio Haka scales well as I moved up and down the dap chain.

    Best matches were with neutral daps, then bright and finally warmer daps (to my ears).

    A good all rounder the Haka performs well with a variety of genres, one the right set of tips is decided on its just plug, play and enjoy.


    The Jomo Audio Haka is a single BA that doesn't skip on performance.
    As I shuffled from soft sultry vocals oozing with luscious mids or switched to an electronic dance track with underlying melody of bass and overlying treble beep beeps or the guitar and drum laden cacophony of rock music new and old the Haka performed respectfully throughout.

    It is a mainly linear earphone that is an excellent all rounder for many genres which I would more expect from a decent dynamic driver earphone than a single BA IEM.

    As mentioned before I had to message JOMO AUDIO and recheck that this was a single BA earphone.

    A bass that is solid and lingering, yet not over powering, a nice taste of mids to bring out the body with a well tuned treble and with vocals softly floating just above it all.

    With a medium sound stage, and an instrument separation that favors a brighter dap, the Jomo Audio Haka also scales well up the dap chain with layering and detail increasing.

    I would use a neutral, then a brighter and lastly a warmer dap with the Haka.

    The fit and sound I viewed favorably and enjoyed listening to without fatigue or discomfort.

    The Jomo Audio Haka is a single BA in ear monitor that veers to a more balanced linear sound with a touch of warmth in the mids.

    Jomo Haka - Control & Conquer
    Written by audio123
    Published Jan 31, 2018
    Pros - Smooth Bass, Laid-back Midrange, Controlled Treble
    Cons - More Treble Extension

    Jomo Audio is a Singapore company that specializes in making handcrafted iems, be it in universal or custom form. Their product line ranges from the entry level Haka to the flagship Flamenco. I would like to thank Jomo Audio for the review unit of Haka. At the moment, you can purchase the Haka at https://www.jomoaudio.com/collections/jomo-universal-iem/products/haka-uiem .


    • Driver: Single Proprietary Precision Balanced Armature Driver
    • Frequency Response: 20Hz – 20kHz
    • Sensitivity: 107dB
    • Impedance: 18 ohms @ 1K Hz
    Unboxing & Accessories

    The retail packaging will consist of the iem itself, 0.78mm 2 pins detachable cable, 3 pairs of silicone tips (S,M,L), 3 pairs of double flange tips (S,M,L), flight adapter, headphone adapter, cleaning tool and case.


    IEM Build & Design

    The Jomo Haka has a glossy black finish to it and the surface is smooth. The shell is made of acrylic. On the faceplate, there is the Haka printed in gold. The gold colour complements the black background. The nozzle is made of brass and it is straight without any metal mesh. I am able to fit the Haka in my ears comfortably. The Haka can be paired with 0.78mm 2 pins cable. Overall, the Haka is constructed well with excellent build quality.





    Cable Build & Design

    The cable is not your usual stock cable. As stated in the specifications, the material of the cable is made of silver plated copper. At the 2-pin connector, you will see a marking of different colours on each respectively. Red colour will indicate the right side while blue colour will indicate the left side. It is a nice touch so users can differentiate between left & right. There is a memory wire area whereby the cable is being enclosed in a transparent heat-shrink tube. It is not very flexible due to the metal inside that helps to form the shape. The cable is braided with 4 wire conductors. The chin slider and y-splitter are translucent clear. The jack is 3.5mm right-angled gold plated and has a translucent clear housing. There is strain relief.


    Sound Analysis


    The sub-bass of the Haka is extended moderately with good control. The rumble is moderate and it is being presented smoothly. Each bass note is expressed with a smooth hit. Although it is not the most impactful, the presentation is musical. The mid-bass has a decent slam to it and it exerts itself well without sounding too aggressive. There is a nice punch to it and the dynamics benefit. The bass operates in a smooth approach that is relaxing to listen to. Bass articulation is rather precise.


    The midrange is moderately clean and operates in a laid-back approach. The Haka displays its midrange in a relaxing manner. There is a good mastery as vocals are being produced with ease. The lower mids has a moderate quantity to it. It is sufficient to tackle male vocals and there are no signs of hollowness and dryness. The upper mids has some forwardness and despite the fact that it is not very forward, female vocals are still being expressed with moderate intimacy. There is a good control in the midrange and details retrieval is great. It is certainly smooth with emotions conveyed effectively.


    The treble is being presented with a moderate extension. There is no sibilance and harshness. It is being articulated in a smooth manner. There is moderate crisp present. The amount of air rendered is great and it helps to prevent the sound from being too congested. The treble is not bright. With such a smooth presentation, the treble will ensure a soothing and fatigue-free listening.


    The Haka has a natural expansion in its stage width. The width has a moderate magnitude to it. It sounds realistic. The depth is not very close in with an effective amount of space rendered. There is a good open feel to it. Vocals and instruments positioning is quite accurate.



    Jomo Haka vs Final Audio Heaven VI

    The Haka has more extension than the Heaven VI for its sub-bass section. There is more quantity to it. The depth is being stretched further on the Haka for more impact. The sub-bass presentation is being expressed more smoothly than the Heaven VI. There is more agility on the Haka as the bass decay is significantly quicker. The mid-bass on the Haka has similar quantity as the Heaven VI but it is presented with more slam which helps to elevate the overall dynamics. Bass texture on both is rendered smoothly and the texture helps to provide a more relaxing listen. Each bass note on the Haka is articulated with more definition. The lower mids of the Haka has more quantity and it does male vocals justice. There is a better expression and male vocals does not sound dry. The upper mids on the Heaven VI has extra quantity and there is more forwardness. The extra forwardness contributes to more intimacy and female vocals are being delivered in a very organic presentation. The Haka still presents female vocals well but the Heaven VI does it better with more sweetness. The Heaven VI expresses them with excellent details. Next, in the treble section, the Heaven VI is slightly more extended. The Haka edges ahead with more body which helps to smoothen the top end. There is more control on the Haka but Heaven VI has more bite. The air on the Heaven VI is greater in quantity. The articulation on both is accurate. In terms of soundstage, the Haka has a more natural expansion in its width and the magnitude on both is pretty similar. There is better depth on the Haka with more space rendered.

    Jomo Haka vs Campfire Audio Orion

    The Haka has more sub-bass extension than the Orion with more quantity. The sub-bass has a better depth. The mid-bass on both has similar body and the slam is moderate. The bass note on the Haka is being presented smoothly and it packs details. Bass decay on the Haka is quicker with more control. On the other hand, Orion approaches it with a more weighted presentation with less impact. The bass texture on the Haka is rendered more smoothly. The lower mids on the Haka has similar quantity as the Orion but it is being expressed with extra cleanliness. Emotions are conveyed more effectively too. The upper mids on the Orion is slightly more forward which results in a nice bite. The Haka approaches it in a calm manner. There is better details retrieval on the Haka. Next, for the treble section, the Haka has better extension and the articulation is more precise. The Haka treble is more enjoyable to listen to. In terms of soundstage, the Haka has better representation with its expansion. Haka is slightly wider and has more space rendered to prevent the depth from being too close in.

    Jomo Haka vs InEar StageDiver 1

    The Haka has more sub-bass quantity than the SD1 and the extension is very similar. There is more control in the Haka sub-bass and it is being presented with finesse. Each bass note on the Haka has a more impactful hit. Bass decay on both is quite similar. The bass texture rendered on the Haka is smoother. The mid-bass on both is not very aggressive but there is a soothing slam from the Haka. The lower mids on the Haka has more quantity and I personally feel it tackles male vocals better than the SD1. The upper mids on both have similar forwardness and there is good intimacy. Moving on to the treble section, the extension is about the same but the Haka operates on a higher level in details retrieval. There is no sibilance and harshness. The amount of air rendered is more on the Haka. I find the Haka to be more clinical and has better mastery. The stage width of Haka is slightly better while the SD1 excels in the depth.


    The Haka is a smooth sounding iem that has a moderate bass response, laid back midrange and controlled treble. It is able to provide details yet ensuring a fatigue-free listening. There is finesse too. In addition, the build quality is good with nice visual appeal. Jomo has produced an excellent iem in the Haka and it delivers.
