    "Upping the Ante"
    Pros - Excellent, well-rounded sound. Sleek, comfortable design.
    Cons - A bit expensive considering the non-removable cable and plastic housings.


    TL;DR: The Brainwavz B200 exceeds expectations with its flagship IEM status, providing an excellent all-around package that embodies the very best of Brainwavz.

    Brainwavz has long been known for being a manufacturer that consistently releases great-sounding, high-quality earphones at price tags that won't break the bank. This combination has been the core of every Brainwavz release since the very beginning. But what if they decide to take all of that experience and channel it into a set of truly extraordinary earphones? That, my friends, is what I'll be covering here today: the Brainwavz B200.

    The B200 is the highest-end model of Brainwavz' brand new balanced-armature B series of earphones, and is priced at a cool $200 – by far the most expensive Brainwavz earphone to date. But does that mean they're the best Brainwavz earphone? Let's find out.

    (Disclaimer: the product in review was received free of charge in exchange for my honest opinion. Please take the following with a grain of salt and always try before you buy.)

    == Aesthetics ==
    Packaging, Accessories


    The Brainwavz B200 is packaged in a compact box draped in Brainwavz' classic black and red colour scheme. Details on the box are minimal at best, which gives off a more serious first impression. Interestingly, the packaging is identical to that of the Brainwavz BLU-Delta I reviewed prior, which may be a move by Brainwavz to reduce packaging costs by using the same box for their products. I have yet to confirm this with Brainwavz themselves, so for now this remains my own theory.

    Inside is Brainwavz' wide earphone case, containing the B200, five additional pairs of eartips, a shirt clip, and a manual and warranty card. Typical Brainwavz stuff.

    Design, Build, Microphonics


    At first glance, I had a hard time figuring out what I was looking at. The B200, for a $200 IEM, seemed quite unassuming with its simple, all-black looks. Its construction didn't do much to impress, either, using plastic housings and a non-removable cable setup derived from the XF200 - thirty-dollar IEMs, mind you. However, over the past two weeks I have taken them on a trip out of town, and they held up wonderfully.

    From further inspection, I found the B200's build to be focused on being lightweight. The plastic housings place no strain on the cable or the ear hooks, which definitely helps with the lifespan of the cable. The XF200-like cable setup has minimal cable noise and thus allows the B200 to be quite suited to those with more active lifestyles.

    Fit, Comfort, Isolation

    The custom-moulded plastic housings of the B200 allows it to stay in the ears securely without making any pressure points on the ear. This, coupled with the moulded ear-hooks, makes the B200 by far one of the most comfortable earphones I've ever worn. Being a balanced armature IEM, the B200 also has inherently excellent isolation, which furthers its versatility for active use.

    Equipment, Burn-in

    The source devices used for this review are a fifth-generation iPod Touch and an iPad Air 2, as well as a Schiit Fulla hooked up to my PC. The test tracks I use for my assessments are of various genres ranging from classical to electronica, with the audio file formats varying from 256 Kbps AAC to 24-bit FLAC. Some of these test tracks will be linked to in the sound assessments to demonstrate certain points.

    Prior to the assessment I listened to the Brainwavz BLU-Delta for at least 30 hours to get more accustomed to the sound – otherwise known as "brain burn-in" – to dispel any "changes" to the sound after a certain amount of time.

    Sound Quality



    Balanced Armature IEMs have long been known to have a flatter, leaner bass response compared to dynamic driver IEMs, but the Brainwavz B200 is a unique exception. The B200 has an unusually noticeable bass punch and a surprisingly aggressive low-end extension, and which might catch some listeners off-guard if they are used to more "traditional"-sounding BA earphones (M2U - Magnolia; Rogue - Ultimatum; Knife Party - Sleaze).

    Despite this, the B200 still has a lean response and at times does not appear in songs that normally require it (Savant - Kali 47). This unique flexibility allows it to maintain its inherently smooth midrange tonality without any of the warmth from the bass driver showing through (WRLD - Style, Everything; Haywyre - Do You Don't You). This, from my observations, could be attributed to a well-designed crossover between the two BA drivers, or simply excellent tuning from Brainwavz. Either way, I'm impressed.


    Throughout my years of reviewing earphones, balanced armature earphones have always impressed me. One IEM in particular -- the Final (formerly Final Audio Design) Heaven II -- remains in my top 3 IEMs that I have ever heard. In my experience with balanced armatures, there is always a certain quality in its midrange texture and tone that is, to me, captivating if not outright hypnotic. The Brainwavz B200 is no different (Yiruma – Scene from My Window, Indigo).

    Despite the bass giving the B200 appeal with electronic genres, it is still a balanced armature IEM. And as with all the BA IEMs I've reviewed, as far as midrange frequencies are concerned, the B200 surpasses my expectations. The way it renders vocals is much like that of the Heaven II -- simple and direct in its tone, but effective in its delivery and rendering of emotion (The Carpenters - Those Good Old Dreams; Coldplay – Shiver). With a midrange like this, the B200 is definitely worth a spot on my top 3 IEMs.


    The Brainwavz B200's treble stands out a bit less in terms of quantity, but does its job of perfectly rounding out the B200's sound signature. It has just the right amount of shine to give you all the details and overtones at the top-end of the frequency spectrum, but not too much that it produces listening fatigue (Sungha Jung – On Cloud Nine). The notable roll-off at the very high frequencies may disappoint those who want more treble extension, but I feel it's a perfect fit for an IEM that does so well with laid-back music.



    The B200's soundstage is no DUNU Titan 1, but it's not bad either. Its dual balanced armature drivers do a respectable job of rendering the illusion of space in various songs. However, it does a particularly good job of presenting instruments in that said space (Eagles - Hotel California).


    With the included Comply T100-tips, the B200’s sound becomes much more like one would expect from a balanced armature IEM – beautifully midrange-focused while retaining treble crispness. So for the most part it loses much of the bass punch from the silicone tips, but still has some of the sub-bass rumble in some songs.


    The Brainwavz B200 takes a very brave path with its unusually boosted low-end. However, by whatever sorcery Brainwavz has done in its tuning, the B200 exhibits impressive bass control while allowing its inherent balanced armatures to sing its own brilliant tune. It is a very well-rounded sound signature that very accurately represents the best that Brainwavz has to offer.

    Other Media


    The B200's versatility extends beyond music, with its smooth sound signature proving itself well with both games and movies. I personally found them to be a blast while playing games, with its great detail retrieval and positioning capabilities combining for an enjoyable gaming experience. However, while enjoyable, they still have its own shortcomings against headphones in this area, particularly in its rendering of space. But if you don't have much else, the B200 will do just fine.

    Amp & EQ Response

    Because of its low impedance and high sensitivity, the B200 is designed to work with low power sources such as phones or tablets. Because of this they performs well enough without an external amplifier. However, when powered by the Schiit Fulla, the B200's overall sound becomes more intense – the bass gains a more aggressive punch, the midrange gains a slight bit of space, and the treble extension and crispness is improved. With an equaliser filter one can also achieve a similar effect – the B200 is fairly responsive to EQ and can handle most tweaks within reason.



    The Brainwavz B200 retails for about $200 on Brainwavz' official website, which thereby makes it the most expensive Brainwavz earphone to date. Now, at this price, is it still a good buy versus, say, the similarly priced MEE Audio P1? I'll make a more direct comparison later, but right now I'm finding the B200 to be a slightly tougher sell than most of Brainwavz' offerings. This is mostly because of the non-removable cable design, which means your B200 has a definite lifespan – once the cable breaks, your $200 is as good as gone. However, I cannot find any fault with the B200 from other angles, so as long as you take care of it, they should last you quite a while. And from my experience, Brainwavz earphones have always been very reliable.



    Versus MEE Audio Pinnacle P1 ($200):

    One of the main reasons I was particularly excited to write this review was because I wanted to see how the B200, Brainwavz' top of the line earphone, would match up against the MEE Audio P1, MEE's top of the line earphone. Knowing that they are both at the same price point, the matchup only becomes more significant in terms of figuring out which earphone to get. But let's not beat around the bush here – all things considered, the P1 is the shinier of the two gems. Simply put, the P1's overall package does so much more for the same price, from its use of premium materials, sophisticated package, and a sound that does so well with everything.

    Of course, that does not mean the B200 is without its merits – some listeners may find the P1 to have too harsh of a treble response, for which the B200 would be a better fit. Others may find the P1 to be too heavy to run around in, making the B200's lightweight build more appealing. Others still might not have an amp and would rather have an IEM that does not need one. Ultimately, your choice of earphone will boil down to personal preferences, so always weigh out the pros and cons before you make your purchase.

    == Conclusion ==


    The Brainwavz B200 is the epitome of great-sounding, high-quality products that are the foundation of all Brainwavz products since their founding. No detail of the B200 was left without purpose. Every facet of its build, every curve in its design, and every nuance in its tuning was done deliberately -- in a way only a company with comprehensive knowledge of their market can. And all of it to make me and you say, "The Brainwavz B200 is the best Brainwavz earphone I've ever heard".

    "Revival of the Dual BA"
    Pros - Musical sound, lightweight, comfortable for long hours, Sits flush!
    Cons - Might be too expensive, non-removable cables, average casing, could have more bass(for my taste), all-plastic finish might feel cheap

    Today we’re going to look at the new flagship Brainwavz B200 Dual Armature earphones. This pair is the new king of the Brainwavz BA series, with two other IEMs in the series, namely the B100 and B150. The B200 is also the highest priced at $277 SGD at the time of writing on their website. Some consider this a revival of the popular Brainwavz B2 dual BA IEM, however i have not heard it thus i can't make any comparison to it. Just how would this flagship fare? Let's find out below.

    Basic Specifications (

    • Drivers : Dual Balanced Armature

    • Rated Impedance : 30 Ω

    • Frequency Range : 12 Hz ~ 22 kHz

    • Sensitivity : 110 dB at 1 mW

    • Cable : 1.3 m Y-Cord, Over the ear, OFC Copper
    • Plug : 3.5 mm, Gold plated


    Packaging & Contents

    As usual, the earphones are packaged in a low-key, minimalist box, with just the model number in front.

    Included in the packaging besides the earphones are

    • A hard case

    • 6 sets of silicon ear tips (S/M/L)

    • 1 set of comply T-100 foam tips

    • 1 shirt Clip

    • Velcro cable tie

    • Warranty and instruction manual

    Gotta give love to the hard-case that Brainwavz provides, as i have mentioned before in my previous reviews, the rectangle-ish shaped hard-case provides more than enough protection for your newly purchased IEM and some extra tips for the road. For a $200 price tag to this flagship model, i was hoping for a more “premium” case like a aluminium hard case or a pelican case that gives more incentives to buyers. Not a deal-breaker as the case provided is good enough.




    The earphones are sport an all-plastic construction with a glossy black finish with very minimal branding along the edges of the shell. The B200 follows the same shell design as the B100 and the B150, a nice small shell that fits the concha of the ear nicely and snugly. Due to the plastic construction, the weight is very light and they sit rather flush and i have no problems sleeping with them on.



    The B200 is meant to be worn over the ear and is aided by pre-formed cables that are super light and does not have a memory effect. The cables on the B200 are non-removable which is really a pity given the price tag, whereby removable MMCX or 2 pin connectors would be great to have. However, this reduces a point a failure as the connection point of the cable and the shell is also reinforced by sturdy strain reliefs, giving extra durability to the product.


    The twisted cables are encased in a soft touch rubber sheath similar to the M100 that is not too springy and feels nice to the touch. The cables are joined at a beefy Y-splitter that has good strain reliefs on both ends and is terminated by a angled 3.5mm plug.




    I generally find the comfort level to be excellent, however it does not sit as flush as my Magaosi K3’s which i reviewed earlier. Don't get me wrong though, it is still very comfortable. I was hoping for removable cables, so users who use balanced cables can take advantage of the earphone more. The build is generally okay, but they do not scream premium or look premium given its premium price tag. However, compared to the popular Audio-Technica IM02 and the ATH-LS200IS, these B200 trumps it in terms of comfort. When shown to friends, they thought it was nice, but they don't look like $200 earphones to them. But this all changed when i got them to try it on.




    I have used this IEM daily for almost a month mainly on my iphone 7 Plus and my Macbook Pro 13 inch on Spotify Extreme settings.

    Song samples:

    1. Console Myself - Rocoberry

    2. Through the Night - IU

    3. Alone - Alan Walker

    4. The One - Kodaline

    5. Skinny Love - Birdy

    This is the most important part of all isn't it? Why would we spend $200 on this IEM?

    Well, when you first put it on, I found the mids to be lush, just the right amount, not too forward, not shouty either, they were in the right place, putting a smile to my face. The had highs the right amount of detail, Not sparkly or bright but just enough for my taste, with zero sibilance in all of my songs which was really a joy to listen to.

    Coming from a triple hybrid, i am spoilt by the dynamic bass driver pumping out nice deep bass that adds some oomph to my songs however, as the B200 is a dual BA IEM, i find this deep bass lacking. I would say they have a nice bass texture and but just a little more quantity and more sub bass extension would be good. However the B200 is advertised producing “balanced and accurate” sound signatures, thus those picking these up might like their song less bassy.

    Overall in terms of sound, there is not one area this IEM is strong in, but it is very musical, with nice layering and soundstage, performing well with the acoustic or more vocal songs however when i listen to pop music or EDM, i would prefer something more bassy. Isolation is above average with this IEM, compared to the Magaosi K3’s which i find really welcoming.




    With a $200 price tag, one might demand more from Brainwavz, i.e a nicer casing, removable cables, more premium construction. With bluetooth audio being more prevalent nowadays, it would be a good idea to incorporate bluetooth cables together with it, assuming that the cables are removable. This would appeal more to buyers who like to listen wirelessly as well as having the option to use it with the standard cable. On the other hand, the B200 is a very pleasant and detailed sounding IEM in the competitive dual BA market with the likes of Audio-Technica’s IM02, ATH-LS200IS and faces stiff competition from the growing hybrid market.

    Gotta thank Brainwavz and Pandora for the review sample. This review has no monetary value and the above comments are purely unbiased comments from myself only.

    The B200 is the 3[sup]rd[/sup] model from the new Brainwavz Balanced Armature series. The B200 shares the same design of the B150, all plastic compact shells in an over-ear fit. For the B150 the build quality was just decent for the ~$100 price, however for the $200 priced B200 it’s much less impressive, considering the many competitors. The cable is standard, soft and well behaved, but thin and lacks a good strain relief at the housing part.
    The small, lightweight and low profile of the B200 is very comfortable as an over-ear fit. The thin nozzle works well for even small ears, and despite the more shallow fit, isolation is very good as a sealed BA earphone.
    The Dual BAlanced Sound
    The overall sound signature is warm, smooth and full bodied. The B200 is probably using dual BA Knowles with a CI inside for the lows, thus the sound is very similar to many other IEMs with a similar BA driver configuration with a certain ‘stage monitor’ like tuning that resembles the Westone UM series with an extra warm boost from the lows. Yet, the B200 is musical and very enjoyable, and could be considered to be darker when compared to the lower priced B150 model. While not a really bass heavy IEM, the low-end is far from being neutral. It’s deep, impactful and very good in texture. Dynamics are surprisingly good for a BA, fast and accurate. In terms of bass quantity the B200 is just a touch short of the UM3x or LZ A4, but obviously far more than the old B2 flagship.
    Midrange is fairly sweet, but not overly full or particularly forward. Well distanced showing good sense of space between the singer and the listener while still having enough sense of intimacy. The fuller midrange carries a more convincing texture in expense of less treble detail. There is a bit of highlight at the upper mid region that helps to prevent it from sounding too dark. The B200 may be missing the crispness of a TWFK-based set, but for a BA earphone the note weight is very impressive.
    Treble is smooth but well extended, delicate and not missing in detail having just enough sparkle and energy. The B200 is by no means for treble or micro-detail fans, however, it is very comfortable and forgiving making the music more enjoyable. Imaging is good and the soundstage has enough depth to prevent the earphone from sounding intimate despite its warm tone and thicker midrange. Width, depth and height are all equally leveled giving a very coherent 3D effect.
    B200 vs B150 (link)
    The B150 already rated quite good in terms of SQ for a single BA driver unit, offering a well balanced sound with a slight mid-centered signature and some extra emphasis at the upper mids and lower treble for a better vocal presentation. While sub-bass is lacking (typical for a single BA at this price) the mid-bass is not missing, with a better than average stage. The B200, however, with a dual BA driver brings a much more balanced and fuller sound from lows to highs. The sub-bass is more realistic, closer to a good dynamic driver, and mid-bass while stronger is also more controlled and nicer layered. Treble is much smoother and forgiving, yet more extended and shows a bit more detail despite being more laid back in nature. Tonally, the B200 is darker and richer which is very noticed in the midrange region, with more weight in instruments and some better coherence and level between lower and upper voices. Technically, the B200 is better, though it’s more a matter of taste as both models are fairly different in their overall presentation.
    While I yet have to try the lower B100 model, the half priced B150 is easier to recommend over the B200 in terms of value for the money. The build quality is nothing outstanding on the B150, and for the B200 is actually disappointing. Comfort and isolation is still well worth. Nonetheless, as for sound quality alone the B200 is well worth its price tag, competing well with more expensive IEM sets, such as the classical UM3x, and giving a good fight to the Dunu DN1000/2000 and the newer LZ A4. The B200 is the anti-thesis of the old B2 in terms of sound presentation, still offering a similar sound quality level.
    Thanks to Brainwavz for the B200 unit.

    "Superb fit with pleasant sonic signature"
    Pros - Excellent ergonomic. Small, light, and very comfortable.
    Cons - Treble might be a bit too soft for some.
    Big thanks to Brainwavz for the review sample of Brainwavz B200!
    Brainwavz B200 is a new Dual Driver, Balanced Armature earphones from Brainwavz, the 3rd model of the Brainwavz Balance Armature series. Excellent ergonomic and pleasant sonic signature seems to be main goals of the design, and in my opinion, Brainwavz has achieved both with Brainwavz B200.

    Brainwavz B200 webpage:
    Here is the discussion thread for Brainwavz B200:
    And here is an informative YouTube video about B100 and B200 comparison by @nmatheis:

    With 30 ohms impedance and 110 dB/mW sensitivity, B200 is smartphone friendly and also we don’t have to worry about hissing noise from some not so quiet sources / DAPs. I do prefer this level of sensitivity to avoid audible hissing noise. I often hear a hissing noise from my 1964 Ears V3 which has a high 119 dB/mW sensitivity and sometimes can be a bit annoying. My Samsung Galaxy S7 can drive B200 quite well, but volume setting most of the time very close to maximum. I do find that B200 benefits from more powerful sources like Chord Mojo and iFi micro iDSD. I especially like the matching of B200 with iFi micro iDSD and iFi micro iDSD Black-Label version that I reviewed a few weeks ago, those DACs really bring out the best of B200.

    Excellent ergonomic. Small, light, and very comfortable.
    Good build quality and seems to be quite durable.
    Treble might be a bit too soft for some.
    Suggestions for Improvements:
    Better quality control on the bending direction of the ear hook.
    Frequency extension for the bass and treble could be improved, especially the treble.

    Sound Quality
    Brainwavz B200 is nicely tuned and leans towards smooth, warm, and pleasing sonic character. Tonality is rather midrange centric with pretty flat response around the midrange area. Overall it sounds pretty smooth without any annoying frequency peak or dip, and no obvious coloration besides the soft sounding treble. There is some roll-off around sub-bass and treble, but in a natural manner and overall tonality still can be considered quite natural. Obviously, B200 is not a bassy IEM, but bass level and quality are pretty good, especially considering that it is a dual BA drivers IEM. Bass is only slightly below the midrange, but coherency with midrange is excellent and the bass doesn’t sound anemic. I honestly have no issue with the bass level. Treble is smooth and soft, sufficient clarity and sparkle but not at the sparkling level of let say ATH-IM02 or Etymotic ER4XR. The rather soft treble might be suitable for those who are treble sensitive, but rather lacking for treble lovers. For me, the treble is a bit lacking as I usually prefer mildly V shape tonality. Therefore I prefer to pair B200 with a treble rich player or source like the iFi micro iDSD, to help to emphasize the treble a little bit. With foobar, I apply a shelf EQ to raise the treble starting +2 dB at 3.5kHz, ramping up to +6 dB at 7kHz onward.

    As mentioned earlier, overall tonality is rather midrange centric, but in a good and musical way, and with good coherent tonality across the audio band. Midrange is clearly the strong character of B200. I don’t usually like midrange centric IEM, but B200 is exceptional as the midrange quality is quite special with very nice tonal density, good body, and midrange clarity. Vocal has good body and fullness to the sound. I’m quite sensitive to a muddy midrange, and usually not a great fan for warm sounding IEMs that sometimes sounds muddy. I’m glad to say that the nice full and dense sounding midrange of B200 has good clarity without any muddiness or fuzziness. The soft treble and dominant midrange might give the perception of warmness to the sound, but I prefer to call it mid-centric. Warm sound usually has a rather long decay around the midrange and bass, and I don’t hear that long decay characteristic on B200. There is a small degree of perceived warmness, so I think we can say that B200 is mildly warm.

    As expected with midrange centric IEM, the presentation is more on the intimate style. Stereo imaging is around the average size, not congested but also not the wide and spacious type. I do wish the dynamic could be a little bit improved. Dynamic is a bit too polite for me, so sometimes it does feel a little lacking in excitement. Probably because I’m quite used with dynamic driver IEMs, the dual BA drivers of B200 don’t seem to move air as much as some of my dynamic driver IEMs. But actually for a dual BA, the dynamic is quite decent as I’ve heard other dual BA IEMs with less dynamic. Other than that, detail and clarity are pretty good, not emphasized but clearly not lacking. Coherency between the 2 BA drivers is excellent, they sound coherently like a single driver. In summary, smooth, polite and mildly warm sounding are probably the main characters of B200 sound signature. It is the type of IEM that will not easily cause ears fatigue even for a very long session.

    Eartips & Frequency Response Graph
    B200 comes with silicone ear tips (3 sizes) and medium size Comply T-100 foam ear tips. The B200 nozzle neck measured 3mm and the nozzle head is 4mm in diameter. The foam ear tips reduce the bass and giving the perception of slightly clearer midrange. I feel the bass is a bit lacking when using foam ear tips, although the mids is a little clearer. Tonality wise, I prefer to use the silicone ear tips in conjunction with a simple shelf equalizer to boost the treble by around 6dB. My impressions in this review are based on the silicone ear tips.
    Before observing the measurement results, please take note of the following disclaimer:
    1. Frequency response measurement in this review was not done using standard measurement instrument for in-ear monitors. Therefore measurement result should not be considered as an absolute result, and should not be compared to other measurement result using different measurement instrument. The measurement was done using MiniDSP UMIK-1 USB measurement microphone with a DIY acoustic coupler.
    2. The program I use for measurement is the famous Room EQ Wizard, REW v5.16. I measured left and right channels a few times, take 2 most consistent measurements for each channel, apply 1/24 octave smoothing, and then average the result.
    3. From my own observation, measurement result beyond 10 kHz doesn’t seem to be reliable, therefore can be ignored.
    Below are all measurement showing left and right channel measurement with both Comply foam ear tips and silicone ear tips. We can see that left and right channels have good balance and consistency.

    Averaged frequency response of both Comply foam ear tips (Red) and silicone ear tips (White) with Psychoacoustic smoothing (closer to human perceived hearing):

    I don’t have other 2 BA drivers IEM with me to be compared with the B200, so I will compare it with my reference IEM for tonality, the DUNU DN-2000, just to observe the sonic differences between them. DN-2000 sounds flat to my ears and measured flat on my measurement equipment, therefore it has been my reference IEM for flat tonality. I also had an opportunity to compare the B200 with Etymotic ER4XR. Only a short comparison, but I will share it here as well.


    DN-2000 sounds more transparent, more extended treble and bass, and the stereo imaging is more spacious and holographic. Overall the DN-2000 sounds more neutral in tonality. DN-2000 also has higher perceived detail and speed. The DN-2000 mid bass and midrange sound leaner than the B2000. The fuller and thicker mid bass and midrange of B200 might be preferable for vocal, but for classical and instrumental that benefit from wide frequency response, DN-2000 sounds superior.


    Etymotic ER4XR
    ER4-XR sounds more transparent and more resolving in detail, with more spacious perceived imaging. More extended and sparkling treble. I like the transparency, but bass is lacking for my preference. B200 has thicker and fuller mids. Vocal sounds fuller with more body. Smaller soundstage with a more intimate presentation. Fuller and more potent bass.
    Both have actually quite different tonality, but both are enjoyable in their own way and don't have any audible annoying peaks and dips on their spectrum.

    Build Quality and Comfort
    Brainwavz has nailed down the design for excellent shape and size for their Bxxx series. B200 ergonomic, to me, is quite perfect to get a very good fit and comfort. 5 stars for the fit and comfort aspect. It is light and fits very nicely to my ears, and very comfortable even for many hours of use. The cable has a nice jacket that doesn’t feel sticky or rubbery. The thickness is just nice for the small and light drivers. 
    B200 is designed for over the ear wearing style. The ear hook is flexible without memory wire. It uses heat shrink tube to shape the cable near the driver housing. I prefer this type of flexible ear hook compared to memory wire. I had small problem initially with the left channel ear hook, where it was not bent to the right direction. It should have been bent inward like the right channel, instead it was bent outward as shown in the picture below.


    I fixed it using a heat gun to bend it to the right direction as shown in the picture. Probably high power hair dryer can be used to fix it as well. Hopefully Brainwavz could give more attention to the quality control to avoid this problem.

    Overall build quality of B200 is great and seems to be able to withstand rough usage. It is the type of IEM that I can just crumple and throw into my bag without worry. And the excellent fit is also great for Sport as it won’t get easily fall off from the ear. The 45-degree headphone jack also has very good cable strain relief. Sometimes I could hear some mild cable microphonic from the cable when used while doing lots of physical activities, but I consider the microphonic as mild and ignorable. Although the design might not be very stylish, but practically it is a very good design with durable build quality.


    The small size and great fit should be among the deciding factors when considering the B200. IMHO, It would be nice if Brainwavz has a version of B200 with microphone for smartphone use. B200 is not for bass heads or treble heads, or those who prefer V shape tonality. But for the treble-sensitive that love a sweet and intimate sounding midrange, Brainwavz B200 is must try. Although basically I’m not a great fan of mid-centric tonality, but I would say the B200 is quite special. It's pleasing and friendly sonic character together with the excellent fit and comfort make it a very nice all-rounder daily IEM. Kudos to Brainwavz!
