I would like to thank Brainwavz for the review sample of R3!
Brainwavz R3 is a dual dynamic drivers IEM. It has 2 dynamic drivers in each housing, facing each other into a sound blending chamber. R3 maybe the only IEM I know to use dual dynamic drivers in this configuration. Frankly, when I saw this configuration at the first time for IEM, I'm quite skeptic. I believe best sound for IEM configuration is to place the driver to face eardrum directly, as close as possible, without any nozzle or sound chamber. I'm a huge fan of Front Mounted Micro Driver (FMMD) architecture, where micro driver is placed at the front of the IEM nozzle directly facing the eardrum, to eliminate any coloration and distortion caused by nozzle and chamber. But I'm open to any IEM configuration or architecture, as long as it sounds good.
Picture from
Brainwavz R3 product page.
R3 uses passive crossover, so it is a two ways design. I would say the coherency between the low frequency and the high frequency drivers is pretty good, clearly much better coherency than my MEElectronics M-Duo. I don't hear any obvious incoherency from the 2 ways design, maybe only a little, but I would say the 2 drivers blends pretty well. But the issue here, I don't hear much wider frequency coverage expected from a two ways system, compared to a one way, single driver IEM such as the Brainwavz S5. I don't hear extra low bass and upper treble extension on R3, frequency coverage is not better than a good single driver IEM.
Summary
Smooth organic sound with rather mid centric tonality. Its unique tonality makes some less friendly recordings (bright / harsh) sound friendlier to the ears. R3 might not be the champion for sound quality in this price range, but with the very solid build quality, it is built to last. R3 would be the IEM of choice for those looking for lasting and durable IEM.
Pros:
Extremely rugged, build like a tank.
Designed for both straight-down and over the ears wearing style.
Very good, above average noise isolation.
Various type and size of eartips are included, for flexible sound tuning and maximum comfort.
The famous Brainwavz semi-hard earphone case is included.
Cons:
The dual dynamic drivers architecture in R3 doesn't proof to be superior compared to a regular properly tuned single driver in the similar price category.
Over the ear cable of the review sample is found not to be properly angled for maximum fit and comfort.
Large housing size might not suit small ears.
Left and Right marking is not easily identified in dimly lit environment. There is no left dot / dimple near the left driver.
The Build
The earlier production batch of R3, before May 2014, has received a lot of criticism as having too long memory wire. As for the newer batch of R3, from May 2014 onward, so called R3 Revised Edition or R3 Ver.2, Brainwavz has removed the memory wire completely from R3, which is both good and bad. Good because there is no more ultra-long memory wire, and the plain cable jacket is generally more comfortable than memory wire. The bad, as some users have reported over the Internet, for over the ear wearing style the cable is not always properly angled to make the cable stays on the ear. For the set I received, I found the left cable often dislodges from my left ear, but the right cable always stays in place. As you can see from the picture below, the left cable is angled outward therefore it is difficult to make the left cable to stays in place. The right cable is properly angled inward, therefore always stays in place. I'm not sure, for all R3, the angle of the left and right cable will always be the same like what I received, or it is different with every piece. If it is different, and you're buying R3, better check the angle of the cable before buying, for maximum comfort. I think this is part of manufacturing fine-tuning that could have been overlooked by Brainwavz. I hope Brainwavz notices this issue and fix it for the newer production batch.

What I like most from R3 is the build. The full metal housing is really nice. It seems to be the most rugged and durable IEM I've ever seen and have. From the mini jack, to cable, to the earphone housings, all feel very rugged. It seems to be built with military standard, to withstand tough environment and application. I always have to treat with care, my favourite IEM, DUNU DN-1000 and DN-2000. Always have a slight fear that the tiny cable won't last very long to hold the solid and heavy metal housings of the DUNUs. But not with R3. R3 is the IEM for those who simply need a rugged and durable IEM that don't require much care.
The cable is relatively thick and a bit coiling, but the coiling memory effect is not very annoying. There are some IEMs with cable with much worse coiling memory effect.
R3 is a relatively large IEM. The dual dynamic drivers and the sound chamber do require space. Despite the large housing, I don't have any comfort issue with R3, even for long hours of usage. The large housing can still fit nicely in my ears concha. But please take note, that it might not be the case for everyone as we have large variety of ear shape and size. For my ears, R3 nozzle is long enough to give proper insertion. So for my ears, I don’t have issue with lacking of deep insertion. The nozzle has standard 4.5 mm neck diameter, compatible with many generic eartips. There is also very minimum driver flex when fitting R3 to the ears, so for those who easily irritated by driver flex, no need to worry about driver flex with R3.
The wires connecting the second driver are exposed; hopefully it won't reduce the durability of R3 from exposures to sweat and moisture.
The left and right marking are clear enough in a well-lit environment, but not clear enough in dimly lit environment.
Sound Quality
As for the sound quality, after using it for more than a month and about 100 hours of burn-in, I would say it is around 'Average' to 'Good', depending on the type of recordings. IMHO R3 doesn't perform well for classical and orchestral works, due to the mid centric tonality, slightly lacking of air, and relatively average size imaging. However R3 sounds better for modern music, such as electronic, pop, and other modern genres with closed miked recordings. Tonality is quite natural, leaning towards mid centric. Beside the mild and wide midrange hump, generally the tonal balance is pretty smooth from bass to treble, without any annoying peaks and dips. R3 tonality won't cause ears fatigue for long period of music listening. Although sometime it does sound a bit boring due to slightly lacking of punch, low bass and upper treble extension. R3 sounds smooth and organic, and not for those who prefer analytical sound signature. Its smooth and rather mellow sound signature actually makes it a very good choice for bright / harsh sounding recordings. R3 is generally easy to drive, but it is better to be paired with a rather powerful and slightly analytical sounding player, to improve the dynamic and treble sparkle.
Sound Signature: Natural warm, organic sound, & mildly mid-centric.
Freq Irregularity: Smooth, no irregular peaks and dips.
Bass Level & Quality: Average, slightly lacking of low bass extension and bass punch.
Midrange Level & Quality: Average, smooth and warm, but level of midrange detail could be improved.
Treble Level & Quality: Smooth & pleasing, but lacking upper treble extension. Not very good for classical music, slightly lacking of air.
Clarity: Average, below the clarity of Brainwavz S5, but not muddy or veiled.
Spaciousness: Average, doesn't sound very spacious.
Imaging: Average, instruments placement and separation are as clear and focused as Brainwavz S5.
Details & Separation: Average.
Dynamic & Punch: Average, not as good as its single driver brother, the Brainwavz S5.
Recording Recommendation: Modern genres (closed miked recording)
I've tried R3 with all the supplied eartips. The Comply T-500 is pretty good for R3, for those who prefer smooth and relax sound. For me, I prefer the default gray eartips for best tonality and comfort. I found eartips selection on R3 is not as critical as on the Brainwavz S5, and it is more to get the best comfort.
Comparison
I mostly compared R3 with its own sibling, the single driver Brainwavz S5. To me, sound quality wise, Brainwavz S5 is clearly the winner. S5 has better dynamic, clarity, detail, bass and treble extension, with wider and more spacious imaging. What disappoint me most is the dynamic. The dual 10 mm drivers don't punch as hard as the single 10 mm driver in Brainwavz S5. Brainwavz S5 as single driver IEM, has better dynamic than R3. Also my old favorite JVC FXD-80, single driver FMMD (Front Mounted Micro Driver), also has better dynamic than R3. So I don't hear any advantage of dual drivers in R3 architecture over a single driver, both from frequency coverage and dynamic. Having said that, R3 doesn't sound bad, but as dual drivers IEM, its performance is not better than some decent single driver dynamic. So I don't hear the benefit of R3 dual drivers configuration.
As I've reviewed other dual dynamic drivers IEMs before, and having some of those such as ATH-IM50 and ATH-IM70, TDK IE800, MEElec M-Duo, & Narmoo S1, in my opinion R3 only wins against MEElectronics M-Duo, but not better than the rest of the dual dynamic drivers IEMs in my collection.
Tonality wise, when paired with good source and amp such my ifi micro iDSD, R3 sounds pretty good. It does need some steroid from powerful amp like the one in micro iDSD to makes it produce some punch.
I did read some very good reviews about R3. Some even prefer it over the S5. Here are some links:

Having read those reviews, it makes me thing that the R3 I received probably doesn't sound as good as theirs. Some reviewers said R3 has clear detailed audio with a clean bass. Which is not what I hear from the set I received, at least compared to Brainwavz S5. Another possibility could be some variation of sound quality from different production batch. Or it could be simply a matter of individual preferences and different preference of recordings. Though sound quality wise R3 is not in the top list of my preferred IEM, Brainwavz R3 has proven itself to attract its own fans from the number of positive reviews.
