    Ocharaku Shizuku - Best bang for your buck <USD50
    Written by Binsterrrrr
    Published Sep 15, 2017
    4.5/5,
    Pros - Price
    Deep punchy bass
    Sparkly Highs
    Nice selection of quality Spinfit tips
    Cons - Midrange might be a little too recessed and distant sounding
    Lack of a carrying case
    Introduction:

    Hello Everyone! I’m Binsterrrrr, an aspiring reviewer based in Singapore. I’ve been in this audio hobby for the past 2 years. I’ve recently embarked on writing my own reviews and am still working on my style of writing, so please bear with me here and feel free to offer any comments or insights for my pieces.

    I troubled a good friend of mine to help me purchase the Ocharaku Shizuku from a store called E-Earphone in Japan. Also, I paid the full retail price of the IEM.

    I own 2 pairs of the Ocharaku Co-Donguri Shizuku. One in Amber Orange and the other in Cosmos. I personally could not pick out any sound differences between the 2 models when using the same tips and source. I will be basing my review on my experience with the Cosmos version which has around 200 hours of run time out of the box.

    I personally find this is a very capable IEM for its price of <USD50 and anyone looking for a relatively affordable IEM should give this IEM a try if possible! Read on to see if this IEM suits the type of sound signature that you are looking for!


    Specifications:

    10mm Dynamic Driver

    Sensitivity:106 dBSPL/mW

    Impedance: 18 Ohms

    Frequency Response: 5 Hz to 40 kHz

    Build Quality:

    The build quality of this earphone does not look or feel cheap despite it costing significantly less than most of the other Ocharaku offerings. The cable does not feel cheap and has sufficient strain relief. Cable to me personally feels very light and not too thick but yet not too thin. Best part of the cable is that it does not tangle easily. The body of the earpiece feels sturdy despite being light and does not feel like a budget product at all.

    Fit:

    The earphones can be worn both straight down and over the ear. However, the earpiece is very light and it can be worn straight down comfortably and that is the method that I use when I listen to the Shizuku.

    Tips:

    Tips change the sound of this earpiece pretty significantly. The stock spinfit tips are comfortable and provide sufficient isolation for me with the M sized tips. However, during my visit to CanJam Singapore 2017, the Final Audio booth was giving out some free Final Audio Type E Eartips which manage to fit the bore of the Shizuku. These tips are my preferred choice of tips with the Shizuku as they make the sound thicker and richer than the spinfits. The lusher sound with slightly better comfort make the Final Audio tips my preferred choice of tips for this IEM. However, this IEM has a pretty common bore size that is the same as the other IEMs from Ocharaku and it would be easy to find other third party tips and experiment with the different tips.

    Sound:

    Summary

    The Shizuku is a warm sounding monitor, a lot warmer than the other Flat-4 offerings from Ocharaku that I own, namely the Ocharaku Flat-4 Akakeyaki Plus and the Sakura Plus. The sound signature of the Shizuku is a slight V-shaped sound. The Shizuku has a lot more bass than I had expected but still had a very nice sparkly treble. Very musical and fun sounding monitor.

    Bass

    The Shizuku packs a really deep and dynamic bass that is unlike that of the other Ocharaku Flat-4 IEMs that I have tried. Bass is boomy and rumbly and not the kind of tight and lean bass. Bass is slow and carries a lot of weight and thus it might not be suitable for those very fast paced music. The bass of the Shizuku might be a little too much in terms of quantity for some.

    Mids

    The midrange of the Shizuku is one of the areas where I was left hoping for more. Midrange might be a little too recessed at times and the vocal positioning is a little too far back for me. When on the Spinfits, the vocals might come across as hollow at times, but when I switched over to the Final Audio Tips, the “hollowness” disappears and the vocals sound more “full”.

    Highs

    For me personally, I find that the treble of this IEM is the star of the show. It has a very airy top end with just enough treble energy for me. It also gives a lot of detail with nice clarity and is rather well extended. Instruments have a natural sounding timbre and cymbals have a lot of sparkle and energy without sounding sibilant to me.

    Soundstage

    The Shizuku has a very airy feel with wide soundstage. Although not as wide as any of its siblings from the Flat-4 lineup, it still has a nice 3D soundstage with good instrument separation. Instruments are all nicely spaced out and does not sound congested in any way at all.


    Sources:

    I used my iPhone 6s, Macbook Air mid 2012, xDuoo x10, Astell&Kern AK240 Stainless Steel and AK380 Copper for this review. The Shizuku scales well with higher end gear but it also sounds fantastic out of the iPhone directly. It is easy to drive and does not really require an amplifier, but it does also have a fuller sound when hooked up to an amplifier like the Kojo KM-01 Brass. Personally, my favourite setup with the Shizuku plugged directly into my iPhone 6s as the synergy between the 2 gives a very warm and musical sound and is very convenient without the need of another external music player.


    Conclusion:

    In conclusion, the Shizuku is a great performer especially at this price range and I would strongly recommend it to anyone looking for an earpiece but is not willing to spend hundreds of dollars. You would still be able to get high fidelity audio from this earpiece from Ocharaku. This IEM would suit genres like POP, rock and it also performs well with classical. It would suit people looking for a slight v-shaped sound signature with bass rumble, sparkly treble and a more airy sound.

    However, this might not be the IEM for you if you are looking for an IEM with intimate vocals and you want the feeling where the singer is singing right next to you. Due to the wider soundstage and more recessed mids, vocals are more backward. Also, the bass might be a little too much for some especially if you do not like too much bass.

    The Shizuku is an IEM that is very easy for me to recommend to people and it is a great all rounder that sounds good out of almost any source. Good job Ocharaku for creating this IEM.

    Intro

    My second IEM review from the Ocharaku company, little known outside of their native Japan. Ocharaku have no distributors outside of their own country and have not been at any of the shows I have attended in Europe. It would be great to have them exhibit their excellent products in Europe or the USA, as lots of us are missing out on a very special signature.
    Concentrating on slowly building up a reputation for no nonsense IEMs which are built to perform , I am sure we will see this company gain a larger cult following that it has already- you may have heard of Stax .
    A Japanese company that could produce IEMs along the lines of the Full Sized Headphones of their fellow countrymen – now that would be something to get excited about.
    We have talked about the mid tier Flat4 Dynamic SUI , this offering is entirely different.
    It is aimed at the budget conscious consumer and that consumer may even dare to exercise with the Co-Donguri. Sacrilege!
     
    [​IMG]
     
    A quick look on the official website
    http://www.trdsn.com/eng/product_codonguri.html
    Reveals the Sky Blue Model testing here is using another patented technology – the Tornado Equaliser. This attempts to address unwanted resonance in the 6 kHz region. The site does not go into great detail as to how this has been done.
    Nevertheless , it’s encouraging to see that even budget earphones are being pushed in their technology. Hopefully , in the right direction. And here’s the fun bit where I get to try them on…..
     
     

    The Set Up Configuration

     
    To get the best from your IEMs its extremely important to work out what is the best fit for you. I always start with the middle ground that the manufacturers set you up with to get you going.
    This tends to be the medium fit tips, although there are often lots of different types of tips. The Co-Donguri was only supplied with the excellent spinfit tips S/M/L.
    So in a way this makes things easier. Spinfit tips are quite the thing at the moment anyway , because they can be twisted all the way round , the driver isn’t being twisted at the same time. I normally find the medium tips fit me quite well , occasionally having to go for a medium small for my left ear.
     
    [​IMG]
     
    No problems here – so it was off to my reference album of the moment which is Legend by Bob Marley.[​IMG] 
    The ‘Legendary’ Jamaican musician who did so much to put the Rastafarian beliefs into Western consciousness and who brought reggae to a Worldwide audience needs no introduction here.
    I plugged the Co-Dunguri into the tiny little Hidizs A60P and leant back into my chair and waited to see what the Dawn Blue could do.
     
     

    Sound Quality

    Bass

     
    The bass is a little soft on the Ocharaku’s, I suspected the Spinfit were not helping the bass to get down and dirty – to push against the contours of my ear canals with that sweltering dub from Trenchtown.
    I looked for a set of Comply’s to remedy this problem. The bass became super bloated and muddied up everything around it in a Beat’s style mess. The spinfits are the correct choice for these earphones.
    I commend the designers in that they appear to have engineered their product with these versatile tips in mind. Living with the spinfits and the Wailers, the lower end sound began to grow on me . The bass is there but it is linear ; bass playing can be heard nice and clearly and drumming doesn’t swamp everything else.
     
     

    Mid Range

     
    The mids had a slight veil to them , making some instruments merge quietly in with each other and Bob Marley’s voice just sink a little too behind his wonderful Wailers. The feeling was subtle and I would be surprised to have this area of the music clear of any imperfections as I’ve yet to hear a perfect In Ear Monitor at any price , let alone £30.
     
     

    Treble

     
    The treble on these earphones have an airy nature, there is a definite shimmery quality to the end notes of the Wailer’s and to the echo which just takes that slight longer to fade into the background.
    I think that treble tuning plays a major part in the building of a soundstage – that place we call where we feel we can pick out the performers positions in the mix. The soundstage is much wider than I would expect from an earphone at this price level.
     

    Comparison

     
    I had a set of Sony MH1s [​IMG]which a headfier from Italy by the name of Guido custom recabled , put memory wire on and sold to me at a similar price level to the Co-Donguri IEM. They are acknowledged as a fantastic sounding IEM for the price level. Guido with his recabling pushed them further. I now have now Custom Earsleeves on them , retailing at £130 , which pushes them to the point were there should be a no contest between the 2 . And yet….
    The MH1’s did have a nicer warmth and substance to the bass, but the mids were more veiled than the Sky Blue’s. Treble and soundstage fared even worse between the 2 – the Sony’s sounded muddy and muffled and pulled in.
    I was surprised to see the Sony’s winning in only 1 of the 3 departments.
    It had , in effect, lost – Miserably. Japan ‘Co Donguri’ David – 2 – Japan ‘Sony MH1’ Goliath – 1.
    Shock win from the under contender trained by Ocharaku.
     
     

    Build

    The build is a stylish one. The Sky Blue metal finish is elegant looking and this fires a shot across the bows of the heavier hitting cousins  , the Flat4 range, which have no finish to them. The diminutive size of the driver shell means a lot more can be put into the ear. This allow for a good sense of isolation from outside noises although the Spinfits don’t isolate as well as Comply Foam Tips. So traffic noise will be picked up and train rumble etc. The music is enjoyable enough to take your mind off most of these mundane things whilst there is enough getting into your shellike to keep you away from those angry cars.
    [​IMG]
    There is no hands free cable facility on these , something often found in IEMs at this price range , the most hotly contended end of the marketplace. It’s always welcome when it’s there , but it’s absent on the Co-Donguri.
    These are durable enough that the website compels you to get out into the World and exercise with them. That’s always good. Music and fitness go hand in hand. Sweat and IEMs don’t always find themselves the best of companions.
    Microphonics , caused by cable noise reverberating into the ears through the driver, is thankfully not present. This is due to the over the ears style of wearing the IEM. The cable is supported by the ear and not by the driver shell wearing it this way.
     
     

    Conclusion

    A great value offering from a company I really hope to spend more time with. I hope they make a leap onto the World Stage and I can say to everyone “I told you they were good”.
    In the meantime a select few know the secret and can take advantage of a really nice inclusion into the Earphonia gallery.
    Until we meet again , Mr Yoshida, thank you very much for your time.

    4.5/5,
    Pros - Massive soundstage, deep base, shimmery highs, excellent detail, solid build, nice tips
    Cons - Comfort, lack of accessories
    I picked these up from CD Japan for only $56 CDN and I have been floored by the quality. I tend to like headphones that excel in imaging and have a wide soundstage. I'm still a newbie in the headphone world so I will keep my opinions brief.
     
    I've owned the following:
    beyerdynamic dt 990 (600 ohm)
    B&O Play H3
    Audio Technica ATH-IM50
    Bose SoundSport
     
    Equipment Used:
    LG V20 (This headphone appears as normal audio device)
    Music from Apple Music
     
    Build:
    The build quality on these is amazing. Really solid construction and the spin-fit tips they provide go a long way to provide a good seal.
     
    Sound:
    When I first tried them, I was disappointed. The sound was hollow, base was lacking and the treble felt scattered. I switched to the larger tip and the bass came back a bit but it still felt restrained. I put it on one of my 8 hour playlists and left them to loosen up. When I tried them again I was at first pleasantly surprised, then shocked and then left speechless.
     
    The base extends very deep to the point that you are left feeling it. The whole bass range can be described as tight and precise with no spillover to the mids. The mids are a bit recessed, but not overly so. Finally the trebles soar and leave you floating in low earth orbit.
     
    From the headphones I've owned these sound like IEM versions of my lovely dt990s.
     
    Comfort:
    Where I find these lacking is in comfort. I love the comfort and stability of the bose and I love the fact that I can sleep on my side with the H3. These headphones are not stable on my ear and side sleeping isn't comfortable either as these babies got a little too much booty and stick out. A soft pillow managed to fix this problem though :p
     
    Other considerations:
    There are hacks that trick the LG into thinking these headphones are high impedance and thus push through more juice to the headphones. I really think they can fly with more power. While I won't be trying these hacks, I will be trying it with the Schitt Magni 2 once I get an adapter...I can't wait to see how these will go :D
     
    Conclusion:
    Amazing sound, incredible value. I bought these with the IM50 and these left them in the dust. The H3 was able to compete in the bass and had slightly better mids but I felt the soundstage was a bit narrower in width and much narrower in height.

    Great price to performance ratio entry level IEM by Ocharaku
    Written by mejoshua
    Published Nov 7, 2016
    4.0/5,
    Pros - Clarity, Imaging, Treble tuning, Fairly dynamic bass, Quality cable with strain reliefs
    Cons - Midrange notes may come across as thin

    Sources: LG G5, Onkyo DP-X1
    Spinfit tips (stock)
     
    When I visited Japan, I felt like a small kid in a free-to-try candy store when I entered the stores of Yodobashi and BIC Camera. They had rows upon rows of earphones available for audition. I had heard a lot about the Ocharaku brand, its unique tornado equalizer driver system, but have not heard their products.
     
    Unfortunately for me, the majority of the models had a treble tuning that overwhelmed my ears. Only one model stood out – that was the Co-Donguri Shizuku. First impressions were that there was a little too much bass, but if I could deal with the treble for more than the duration of a song, it held promise. I wanted to grab a pair but at that time I found out only the demo was available and not for sale because it was still yet to be released.
     
    Fast forward several months – I got the help of a friend to bring back a pair for me. Coincidentally he managed to get a limited edition version in Amber Orange, purportedly with a sound that was slightly better to his ears than the regular Shizuku. With excitement I got it in my hands once he was back and plugged in.
     
    Before I go into the sound, just a few comments about the package and build:
    It comes in a simple plastic box, but the great thing is that it comes bundled with Spinfit tips, which can be fairly costly depending on where you are. I find the Spinfits very comfortable to wear and slips in and out of my ears easily. I was also impressed by the cable quality and the solid build of the strain reliefs. The cable is soft and pliable and retains little memory. It looks and feels like a quality cable and belies its pricing. The wood(?) shells are a nice touch, and I have a suspicion that it may sound very slightly different than the usual Shizuku models because of the materials used on the earphone shells.
     
    I gave the Amber Orange (AO) about 100 hours of running in before doing any analysis or critical listening, even though it sounded quite good fresh out of the box. The primary discernible differences are that bass got a bit tighter, and there were some improvements in vocal clarity. Imaging also got a little more focused.
     
    What strikes me first is the separation and clarity that the AO brings to the table. There is a good sense of air, and what may best describe it is the feeling of openness, almost akin to listening to open cans. In my mind I’ve always maintained that earphones will never be able to replicate the staging of open cans simply because of the nature of the technology used e.g. driver size and ventilation, and I still hold on to that, but surprisingly the AO does come close. The caveat is that when it comes to soundstage, the AO does more width than depth, with average height. Also, the nature and quality of the recording also contributes to the extent of how open sounding they can get. I suspect the openness is possible because of its vented design. It is definitely more challenging for customs or non-vented designs to sound open. Its imaging abilities are outstanding. Coupled with the clarity, the imaging is focused and you can clearly delineate where instruments are placed on the stage or in the song. Most IEMs at this price tier can hardly get this level of clarity, much less the imaging ability. 
     
    Let’s start with the bass. One of the things that characterize a dynamic driver bass is the amount of air it moves, as compared to a BA setup. In other words, you can actually “feel” the bass instead of just hearing it. This is what is happening for the AO. What I really like about it is that the bass textures are conveyed to the listener, especially the rumbles and the reverberations. The speed of decay is just about right – not too fast as to lose its weight and impact but not slow enough to make it muddy and bloated. There is good control over bass impact – not overwhelming but enough to make you feel like grooving to the music.
     
    The midrange comes across as clean and natural. When I say ‘natural’ I mean that its tonality is quite organic, and vocals do sound close to how they would sound in real life. This is particularly evident in acoustic tracks, where the voices are accompanied sparsely with a guitar or piano. There is also a bell-like clarity that is astonishing at this price. This is no giant killer but it competes at a level a few notches above its price tier. However, one caveat is that the midrange note may be considered on the thin side, which aids its clarity but not suitable for those who like weighty, thick mids.
     
    Lastly, the treble is very accurate and has no tendency toward sibilance or fatigue in any way. I get decent extension and correct timbre with a lot of detail, which in my book reflects the quality of its tuning. Less surprise here, since the Ocharaku models have always been quite treble-oriented, even though the AO stands out because it is a model I can actually listen to over an extended period of time – one that I don’t find overly thin, splashy or overwhelming with treble detail. Coupled with its excellent separation, I can hear clearly defined cymbal hits even in rapid succession.
     
    Even though from my listening history and preferences I tend to enjoy a touch of warmth in vocals and prefer it to strict accuracy of vocal reproduction, I really feel that the AO is interesting because it is quite accurate without making it sound clinical. I find that the AO is a very special IEM that I will keep for a long time mainly because of its ability to sound out of the head in its soundstage width, and its organic and detailed vocal reproduction. Together with very good bass and accurate but inoffensive treble, the AO is a no-brainer at 4960 yen or about $50 USD. The only problem is that it is incredibly hard to find outside of Japan, so do consider picking one up if you happen to be travelling there!

      Thanks so much @mejoshua . A tiny bit torn between these and the Shozy Zeros - they're for 20 somethings who are not audiophiles, so I think they'll be happy with either....slightly tempted to pick up two pairs of each, have a listen, and then give extra gifts to friends! Big thanks for the clear and concise comparison - and so quick as well!!

    Some "Provenance" to the Brand Name:
     
    Ocharaku is a "tea themed" company based in Japan. Focusing on Dynamic Driver IEM's, Ocharaku pushes the envelope when it comes to breaking the negative "dynamic driver" stigma (Balanced Armatures being viewed as the superior transducers by audio snobs). Utilizing resonance chambers and other proprietary technologies, Ocharaku is pushing the boundaries of dynamic driver IEM's, destroying the placebo of "more drivers= better sound". Despite developing reference class IEM's, Ocharaku is a relatively unknown brand, remaining a niche domestic brand in Japan's audiophile market. However, Ocharaku has garnered a passionate cult following of South-east Asian users, especially those looking for a "purely-reference" sound. Paired with Ocharaku's striking "aesthetic" and unorthodox driver designs, Ocharaku is a rebellious brand that refuses to conform to "audiophile" norms (refer to picture below).

    Despite their large catalog of earphones, their hefty price tags coupled with the clear lack of marketing has mired their potential to penetrate overseas markets and further expand on their horizons. Many of their distributors are all based in Japan (e-earphone.net being the biggest). However, without announcement, Ocharaku has released an affordable follow up IEM to the Ocharaku Donguri Raku (Approximately 150 USD). Featuring a "Tornado Equalizer" and a single dynamic driver, this is officially Ocharaku's cheapest and most accessible IEM to date. The reception so far has been rather tepid. Costing less than 50 USD, I decided to own my first pair of Ocharaku's, albeit being the cheapest model available. I managed to snag an almost brand new pair for approximately 35 USD in Singapore. This is my honest and in-depth review (these were not sent in and I'm in no way affiliated to Ocharaku or its distributors).
     
     
     
    Accessories Package:
     
    codonguri_img06.jpg
    Available in 3 Colors (Dawn Blue, Silver Moon and Smokey Gold)
     
    Understandably, most reviewers on Head-Fi offer snapshots and pics of the contents provided when it comes to any given product review. Sadly, the standard Ocharaku Co-Donguri package is rather sparse. The miniscule box is representative of that. The package includes:
     
    1 x Ocharaku Co-Donguri IEM
    1 X SpinFit Tips (S,M,L)
    1 x Instruction Manual
     
    I am somewhat disappointed by Ocharaku when it comes to the lack of a carrying case . Even budget IEM's that cost less than 40 dollars in the Chinese IEM Market come with a little faux-velvet pouch to store IEM's. However, the provision of  ​ tips is thoughtful, especially when the retail value for SpinFits are considerably high.
     
     
     
    Build Quality:
     
    I have to say, these are "interesting" with respects to its design. The back of the IEM has an interesting bead blasted finish (akin to pebble), which provides easy-grip when it comes to the placement or removal of the earphones from your ear-canals. The entire IEM feels as if it has been "CNC" Machined and Manufactured, thanks to it's solid aluminium construction, being both lightweight and durable enough to take a beating. Do take note that the "front" and "bead blasted back" of the IEM's appear to be modular, as though these two parts are somehow "glued" or bolted together to form the driver housing (refer to picture below)
     
     
      codonguri_img04.jpg
     
    The nozzle length paired with the superbly comfortable SpinFit tips make for a deep insertion, ensuring a snug fit. Any sudden movements are unlikely to displace the IEM's from your ears. The strain reliefs are ingeniously designed. The "inverted" or "angled" strain reliefs are hard plastic, molded over the cable sheathing to offset the weight of the cable and prevent cable-driver separation, a common issue with IEM's without removable cables. The cables are supple and nice to the touch, being pliable enough to  wear "under" or "over-ear". Oddly enough, the cable sheathing has a strange perforated "tubing" design. Overall, you are definitely getting more than you pay for when it comes to its build.

    I have to admit on my part that these IEM's "WOWED" me on first listen. I'm not a fervent believer of "burn in" vs "psychological burn in" per se (audible differences aren't exactly night and day), but I decided to remain as objective as possible. I burned them in for approximately 20 hours without prior listens (to prevent unconditional biases from kicking in). The IEM's are rated at 18 ohms, so there shouldn't be any worries when it comes to driving these IEM's.
     
     
    I was floored by the unobtrusive yet shimmery highs. Cymbals, Stringed and Wind instruments had a eerily accurate timbre/resonant reproduction unlike anything I've ever heard in this price bracket. The higher-end had just enough forwardness and grit to be considered "natural", with a slight tinge of sibilance. Female vocals, especially by vocalists in the "Mezzo Soprano" region such as Neko Case were larger than life, with an uncanny resemblance to a front seat performance. Male hymns or European Folk Groups such as Dry the River were represented beautifully by the Ocharaku's. It's almost impossible to describe and best left to the listener to decide for himself/herself.

    The mid-frequencies were clear and remained unaffected by the usual bombastic lows that or often characteristic of poorly optimized dynamic drivers. The highs took center stage but the mids followed suit. The lows had a "shy of neutral" tuning, with mid-bass thumps akin to a balance armature with a tad more sub-bass decay. 
     
    For a budget IEM, the sound-stage trumps many of it's competitors (even those that cost up to 8 times more). It's sound-stage, while not as wide as a flat-plain like some of its balanced armature counterparts (with their faux left-right channel separation that comes as off unnatural at best), the Ocharaku's recreate an incredibly clear and coherent sound-stage. Imaging was a blast, with instruments/backing vocals being well positioned and easy to identify. IMHO, the Ocharaku's actually sounded better than my previous daily beaters! (the Noble 4 to be exact)
     
    Overall, the Ocharaku Co-Donguri is a stellar single dynamic driver that gives its competitors a run for their money. Do take note that they paired superbly with my  and  ​ but sounded a tad to forward and somewhat fatiguing when paired with the  ​  (YMMV)
     
     
     
    In Conclusion;
     
    I was left completely speechless. When it comes to price to performance ratio, the Ocharaku's are an easy 1:10. As stated previously in a review I did on the ever-changing FLC 8S, I stated clearly that I hated single or multiple balanced armature setups due to it's unnatural tingey sound and psuedo "left to right" sound-stage. These Japanese beasts are living proof that dynamic drivers can be superior to multiple driver setups if done right. Sometimes less is more, and in this case, they are WAY more.

      @JaeYoon Woohoo! I'm also wondering the same, but have a pair of PM4 on order. I'm at once excited and apprehensive. Trinity has been excellent in quality but not entirely to my preferences. Expect it to be better this round however due to the sheer number of filters. I'll do a small comparo on the CO-Donguri Shizuku thread when they arrive, will likely use WGB songs to test haha..

      @yoowan it boils down to preference . For a non-fatiguing, well balanced sound, go for the 1more. If you like a thinny/reference sound, get the ocharaku. I prefer the ocharaku

      Thanks for your input. I already have the triple driver but I've discovered that I prefer soundstage and clarity over bass performance. I took the plunge and I ordered the Ochakaru on cdjapan. I hope I will like it.
