[Bass]:
The tuning of the bass is definitely one of the dynamic driver kind of sort of bass performance.
It is very commanding, punchy with very solid rumble .
This Rinko will therefore appear particularly suitable for electronic music, rock music, or any other type of vibrant contemporary music.
Even though the Midbass has a lot of presence, rumbles, punch, and everything in between it doesn't dominate any other frequency, especially the subbass or lower midrange.
What I'm trying to say is that it doesn't add any bloat or woolliness to the sound.
I can still clearly hear the subbass region dispersing or transitioning into the decay stage with a very smooth transition as it goes deeper and deeper.
As a result, I would say that the extension for Rinko on bass is definitely quite amazing.

[Mid Range]:
The midrange produces better sound than the treble.
Indeed, even the bass can't overwhelm the presence of the upper mid reach because of how lively and effective it sounds in the general blend.
Regardless of having this much energy, the vocals aren't so expressive as I had trusted given how forward they are.
On the other hand, the instruments can sometimes overwhelm the vocals, preventing them from moving forward.
In terms of presentation, the instruments sound disorganized and the vocals, particularly those of the female singers, lack clarity.
There is no metallic timbre to be heard because the sound itself caves before creating openness or a rich region.
A very thick and primitive sound is produced by the mumbled vocals and muffled instrument sounds.
The midrange as a whole has a sound that is very thick, bouncey, and vague.

[Treble]:
The High pitch reaction is well smooth, it's definite, it's rounded.
It is treble not like Planar, thus a micro planar expression actually makes sense .
The vocals struggle to keep up while maintaining their distinctive characteristics. The energy feels out of place, and the lower treble also sounds strange.
The instruments sound relaxed and detailed without sounding metallic, while the vocals have a front and expressive response in the mix.
Overall, the treble region's presentation is enjoyable & playful.

★Technical Performance★
soundstage isn't that wide but not bad either but for my preference it is a bit narrow .
you will get a feeling of holographic presentation .
with binaural kind of tracks, or even gaming, I was able to hear, cleany the placement of instruments or sound sources, regardless from top, bottom, left, right, anywhere, you name it .
I play FPS game csgo most of the time so enemy position where they are coming from i can have a decent visualization of it .
Imaging is good for its price .

★Tips rolling ★
if you want to minimize bass use any silicone tips ,it will reduce bass thus might be into your likings territory .


Rating:

Bass: 4.5/5
Mids: 3.8/5
Treble: 3.6/5
Imaging/Separation: 3.7/5
Staging: 3.8/5
Dynamics/Speed: 3.7/5



★Conclusion★

Rinko is a fun & bassy IEM with great upper mid energy .
I have to admit that these IEMs are different from what I usually hear, (cause i'm quiet liking neutral tuning ) & their response is different from what I've heard before.
sometimes you need something different in your collection so it is worthy to give it a shot .
In a busycity you might need to relax, cause surrounding you everything seems very loud just plug them into your ears and let the bass mellow your brain .

Design​

When I unboxed Rinko, my first thought was how much it resembled the Truthear HEXA. The aluminium faceplates and translucent 3D-printed resin shells share a similar matte black finish and feel.

The slim shells are not only aesthetically pleasing but also exceptionally comfortable. However, they offer little passive noise isolation. Rinko features standard 0.78mm 2-pin sockets, aluminium nozzles, and a single vent on the rear side.

Included with Rinko is a twisted oxygen-free copper cable. The straight plug and Y-splitter boast a polished aluminium design, while the chin slider and connector housings are made of clear plastic. Although the cable feels somewhat generic, it performs well, despite having a slight memory effect.

Verdict​

In summary, the SeeAudio x Z Reviews Rinko IEM offers a unique sound signature with its emphasized bass and lifted upper midrange. It delivers a bold and intense listening experience. However, the recessed lower mids impact vocal intelligibility. The lower treble region provides clarity, but the subsequent dip limits the presence of harmonics and fine details.

While Rinko performs reasonably well, there are numerous other options available in the market that offer better overall performance. There are more compelling alternatives but the waifus alone might be enough to make you pull the trigger on this one.

Introduction​

SeeAudio and Z Reviews have collaborated to create the Rinko in-ear monitors, a dual-driver IEM with one planar and one dynamic driver. This review by The Audio Store team explores Rinko's sound signature, design, and build quality. Read on to find out if Rinko is worth considering for audiophiles on a budget.

Design and Build​

Rinko's treble response is clear, crisp, and pleasant, producing all the details effortlessly. There's no harshness or sibilance in the treble, making it enjoyable to listen to.

Pros and Cons Pros:​

Conclusion​

The SeeAudio x Z Review Rinko IEM is an excellent choice for those who appreciate textured bass and crisp treble with a warm midrange. Its dual-driver combination of one planar and one dynamic driver produces a safe sound signature suitable for all music genres. It's also comfortable to wear for extended periods, making it an ideal choice for audiophiles on a budget. Its cons, including a narrow soundstage and less depth, might not suit those who prefer a more grand-sounding setup. Overall, the Rinko is a nicely tuned in-ear headphone that offers exceptional value for money.

Disclosure:

In regards to the See Audio Rinko driver speculation, I was contacted by HiFiGo.

“Rinko’s 6mm driver is a newly patented planar, try it yourself, we are happy and open for a third party audit“

So I kindly accepted that third party appraisal offer.

Here we go.

Chapter 0.
SeeAudio Rinko controversy —the background


—About SeeAudio
Most of us would have already known who SeeAudio is, a relatively young IEM brand that initially caught public attention by Yume, Bravery, with their highend Neo, Kaguya being flagship and over the years the company has established itself firmly in the international audiophile community.

—qdc, is that you?
There is a rumor that SeeAudio was started by ex-qdc engineers and I personally get that rumor because their tuning is in qdc’s blood.

... I should also clarify that I am an avid fan of qdc tuning and rate the SeeAudio Bravery (with aftermarket re-cabling and ear tip changes) as one of the endgame IEMs for female vocals. 10BA, 14BA, EST, all couldn’t produce what I refer “fragile and translucent“ timbre that Bravery is capable of. Its tone resonates in your brain as pleasantly as the light sound made when you lightly tap your finger on a wine glass.



Anyway! My personal recommendation aside.

Chapter 1.
SeeAudio Rinko controversy —the Driver speculations

By now many of us may know there was a series of dramas surrounding Rinko‘s driver.

The driver of Rinko didn’t look like conventional Planar Magnetic Driver that we see on, say, 7Hz Timeless or Tangzu Wu Zetian.

It is referred as “6mm Micro Planar Magnetic Driver (MPMD hereunder)” and this specific driver brought a series of discussions over the internet about whether 6mm MPMD is a legitimate Planar or not.

Amidst the buzz on the Internet, Rinko seems to have attracted more attention than expected.

As we all know there's no denying that internet flame wars have an intriguing and entertaining aspect to them.

As it stands, HiFiGo's disclosure of the MPMD patent information obtained from SeeAudio's design, as well as the release of new disassembled images of several Rinko drivers, seems to have put the confusion to rest and put the situation to rest.





My understanding is that the "Micro Planar Magnetic Driver" is a new type of Planar Driver that "specializes in a specific frequency band" and I actually realized how good it is when Rinko's sound was tested.

So here comes Rinko.

Chapter 2.
SeeAudio Rinko sound, is it a dynamic or planar sound?

Before we step into the sound, I guess it is noteworthy to show this carrying case.



Wow! Looks like an engagement ring case, that’s quite a good job selecting case from various candidates, I value carrying case with significant weight in decision making because it ultimately comes to “if carrying case is bad looking it’s not worth as gift candidates especially if you are gifting to your wife or girlfriend”.

Anyway, back to sound.



—Tuning
Frequency Response Chart



Both Rinko and Tangzu x SeeAudio Encounter shares very similar take on basic tuning philosophy.

Both IEMs are tuned for the following characteristics
▶︎ Wide staging feel
▶︎ Extremely careful sibilance dip
▶︎ Emphasis on upper mids for forward projection of vocals and sound image.
▶︎12kHz and 16kHz diffusion field border articulation and air generation.

Encounter maintains a relatively neutral bass range and improves tonal balance on acoustics, while Rinko emphasizes the lower midrange and creates musical excitement in digital genres.

—A million dollar question and my main reason to be called in auditioning Rinko

️Is it Planar or Dynamic?


To my ear, Rinko’s timbre is a hybrid of Dynamic and Planar with following structure:
Bass : Dynamic
Mid : Dynamic
Treble : Planar

Certainly there is a hint of planar in Rinko's upper register, but compared to a full planar like 7Hz Timeless, I would say that 70% of the timbre is derived by dynamic and 30% by planar.

7:3 dynamic : planar

Immediately after unboxing, there was a rough texture like that of piezoelectric, but after about 8 hours of aging, the roughness was smoothed out.

As a result, compared to the piezoelectric, the sound image localization is significantly more recognizable as Planar, with a unique sound pressure and resolution.

For the tonality per se, Rinko has a strong dynamic impression overall, and the planar is effective only in articulating details and expressing a sense of air and finesse.

Thus, Rinko in a sense is “dynamic-like sounding” yet “has traits of Planar timbre in upper registers”.

This is why I mentioned above that Rinko’s "Micro Planar Magnetic Driver" is a new type of Planar Driver that "specializes in a specific frequency band". It is treble only Planar, a micro planar expression actually makes sense to me now.

Now, I think I have fulfilled my role as an inspector with the above comments.

I would like to continue with the review as usual.


—Timbre Impression : Sound Tasting
Following the manner of expression in perfumery and wine tasting, the components of the sound are described below.

Top Notes: Clarity, rounded, soft contours.

Heart Note: Densely textured, with a solid presence in the upper register

Bottom Note: Overall thickness of sound, authoritative sub-bass

— 6mm MPMD’s forte

Although Rinko's finesse expression is supposed to be the timbre of the brand-new 6mm MPMD, the fact that one can feel a clear and distinct line in the core of the sound is a melancholy that is fundamentally similar to the UE TF10Pro, which I once loved and bought four of in total.

Yes, that Triple.fi 10 Pro of Once the mighty Ultimate Ears.

Review Of The Seeaduio x Z Reviews Rinko​

Introduction​

Since many of Seeaudio's in-ear monitors (IEMs) have received high praise for their performance, the company has a large following among audiophiles. The Yume siblings—the original and the midnight edition—are two of the many IEMs they have released that I like. I've reviewed Yume Midnight before, but today I'll be talking about their latest release, Rinko, which is the result of a collaboration between the well-known YouTuber Zeos Pantera and SeeAudio. But let's go over a few things I want to make clear before continuing with the review.

Disclaimer​

*Since this unit tour was organised by the wonderful people at Hifigo, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as "Rinko."
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the Rinko based on their performance, even though I will explain how it feels and seems physically and aesthetically.
*As a reviewer who prioritises sound over all else, I dare not care about recent conflicts with the real story behind the Rinko. Instead, I'll do my best to focus on how they perform rather than the strategies used or the reasons why misunderstandings occurred.

Specification​

A 6mm micro planar driver and a dynamic driver are used in the hybrid driver configuration of the Rinko. The shells are made of high-quality materials and are lightweight but very rigid. The shells are the ideal size for my ears and prevent ear fatigue during extended listening sessions. The cable has four silver-plated OFC strands, a 0.78mm connection for the IEM, and a straight 3.5mm termination plug on the other end. Three pairs of ear tips in various sizes, a cable, and a carrying case are included as IEM accessories. Technical details include a 30 Ohm impedance and a 112 dB sensitivity. 20Hz to 20kHz is the range of the frequency response.

Sound​

According to what I have heard, the Rinko sounds strange and very different from what I have always heard, but it hasn't stopped me from learning it because the tuning is very much V-shaped with a focus on the upper midrange and the bass region. I describe it as odd because the tuning is off for me; the treble tries to sound expansive, but it doesn't perform as one would anticipate; there is some positive energy, but it sounds dishonest to my ears, which is contrary to how I typically hear music. And even though the upper mid range has a lot of energy, it doesn't sound in the slightest bit peaky or bright. It doesn't let the mid range down, in fact, the upper mid range sounds soft as a result of this influence, in my opinion. The bass sounds booming and punchy at the same time with a lot of presence in the overall mix. All I'm trying to say is that, despite appearing to be tuned differently, the V-shape signature still sounds the same. Let's investigate the sound more in depth.

Treble​

The treble region's energy is quite playful, as it can sometimes sound very intimate with high energy when listening to rock or pop tracks, and it can also sound expansive when listening to quiet tracks. With complex tracks, the upper treble loses its extension but still sounds wide. Although they appear tainted and rough due to the lack of details and texture, they do feel rounded and bold when combined. The vocals and instruments are mixed well, but even though the vocals extend well into the upper treble, they still feel unfinished. The same is true of the instruments, as sometimes the cymbal crashes sound expressive while the snare hits are unimportant. Listening to these gives the impression that the sparkle usually stays in this area. The vocals struggle to keep up while maintaining their distinctive characteristics. The energy feels out of place, and the lower treble also sounds strange. The instruments sound relaxed and detailed without sounding metallic, while the vocals have a front and expressive response in the mix. Overall, the treble region's presentation is enjoyable, enjoyable, and playful.

Mid Range​

The midrange sounds better than the treble because it is more familiar and relatable. To be completely honest, the upper mid range region continues to hold the majority of the energy. Even the bass cannot overpower the presence of the upper mid range due to how energetic and impactful it sounds in the overall mix. Despite having this much energy, the vocals aren't as expressive as I had hoped given how forward they are. The vocals, on the other hand, are sometimes overpowered by the instruments, which has the effect of holding them back. In terms of presentation, the vocals, particularly those of the female singers, lack clarity and sound blunt, and the instruments sound disorganised. Since the sound itself caves before producing openness or a rich region, no metallic timbre can be heard. As the vocals and the instruments lack personality and sound drowned out and very dull, the lower mid range is mellow and relaxed. To be honest, the presence of bass greatly muffles the sound in this area. The mumbled vocals and muffled sound of the instruments create a very thick and primitive sound. Overall, the mid range has a very thick, bouncy, and vague sound.

Bass​

Whether it is the sub bass or the mid bass, the bass is overwhelmingly present in the overall mix. Due to its prominence in the mix, the bass has a significant impact. The deep sub bass is the focus, but there is also a lot of mid bass in the mix, which bleeds into the mid range and essentially masks the lower mid range as well as taming the erratic energy in the treble region with some influence over the upper mid range. Even though the upper range seems more accessible, the bass actually occupies a significant amount of the mix. While the mid bass region is where the slams and boomier presentation hits greatly, the sub bass region sounds impactful with punches and gives a good sensation of rumble. The bass line is thick and has an organic feel to it. Although the bass's expression of the details or texture is poor. Despite the overwhelming amount of bass, it doesn't live up to my expectations in terms of quality. The bass hits hard but resolves poorly, sounding like it has no control over it. Overall, the bass region sounds boomy, punchy, and scattered throughout the overall mix.

Technical Performance​

The Rinko is an average sounding IEM in terms of technical performance; the stage is large, the imaging could be better, the separation is hardly perceptible, the details aren't particularly forthcoming, and the resolving speed is sufficient to maintain the mix's flow.

Soundstage, Sound Imaging & Separation​

Even though the positioning isn't particularly good, the soundstage is wide enough to sound quite spacious. The imaging could be sharper and better with overall clarity, which would make it more enjoyable. The separation is barely discernible because there isn't enough room for the components to breathe while still being distinct enough to identify their sources. However, it hardly prevents it from being messed up.

Speed & Resolution​

The resolution is also not fully appreciated because the details are hesitant to come forward and are not very exploitative in nature. Even though the deacy is not as good as I had hoped for, the notes attack quickly enough for a tidy presentation.

Sound Impressions​

Sources​

Tempotec V6 - The Rinko sounded much better and cleaner when paired with the V6, with more clarity in the treble and lower midrange. Although the upper mid range felt a little muted and the bass remained unchanged. The resolution and imaging felt better, but the technical experts felt the same. Compared to other pairings I tried, the V6 pairing felt much better.

iFI Hipdac - When used with the Hipdac, the Rinko produced a bassier and murkier sound. The upper mid range and treble were slightly more subdued. To be completely honest, the entire response sounded friendly and lively. The details felt the same because none of the other characteristics or the specifics had changed. The Hipdac pairing was also entertaining to listen to.

Conclusion​

Rinko is a fun and bassy IEM with good upper mid range energy, which makes it sound exciting and fun to listen to, to conclude this review. I must admit that these IEMs are different from what I typically hear, and the response they produce has a distinctive characteristic compared to the others I have listened to, which begs the question of whether or not they are worth the price. Therefore, in my opinion, one should first try it.

2023 is all about collaborations, we are just three-four months in and we have already got so many collaboration products. Just a few days back I completed my review for the See Audio x Tangzu Audio Shimin Li Encounter Edition, a collaborative project between See Audio and Tangzu Audio. Today, I am going to bring a review for another See Audio collaboration, the See Audio x Z Reviews Rinko. Rinko is actually the talk of the town currently mainly because of a driver-related controversy that’s going around. Basically, things are going around about the verification of its planar driver unit. People are talking and engaging in a lot of discussions over this, and that got me curious to do a teardown myself. Hifigo has also posted a teardown that shows the internals which has increased my curiosity even further. So, I have joined hands with a friend of mine to tear down my unit as well. I will be adding a teardown section later in this review, but first, let’s find out more about the Rinko design, build, and sound!!

A Short Disclaimer Before I Begin:

The See Audio x Z Reviews Rinko was sent to me as a review sample from HiFiGo. There is no monetary benefit involved in this review, I would like to thank HiFiGo for providing me with this sample unit. I have enjoyed a good two-week period with the set, and now the set is actually not working for me as I messed up during the tear down(actually broke the planar shell for the left side driver unit). But the teardown and my review are complete that’s the good thing here. At the time of this writeup the unit retails for 99.99$, you can go and check out more information on the HiFiGo page below(It’s a non-affiliated link).

About See Audio x Z Reviews Rinko:-

As I mentioned above, Rinko is a collaboration between See Audio and Z Reviews. It’s a dual-driver hybrid set of IEMs featuring a dynamic driver and a micro planar driver unit as advertised by the brand. The pair has attractive pricing and comes with a beautiful waifu designer box package. That’s almost everything that everyone knows now, let’s begin directly with the unboxing experience for the set.

Unboxing The Rinko:-

See Audio makes good packages for their IEMs. I was so in love with their Yume II package design, it looked so beautiful. The Package of Rinko has a designer look with waifu design right on the slip-on cover. On the back, we have the technical details and another image of the waifu. They have named this waifu Rinko(as evident from their keycap set as well). I have also got a stander of Rinko, which is a good-looking designer item(my wife has already called her dibs on this stander). Inside we have everything we need to get going including the pair itself, a 3.5mm terminated 2-pin cable, three pairs of new silicone-foam hybrid ear tips, a carry case, and a user guide. There’s also a cardboard-style stander inside the package with the Rinko waifu image exactly as we have on the front of the slip-on cover. Too much waifu in the package!!! But overall a good experience for unboxing a 100$ set. The new Eartips are quite good, will share more about them in the design and build quality part.

Package Contents:-

>Rinko IEMs.

>3.5mm terminated 2-pin cable.

>Three pairs of New Render Ear tips.

>Carry Case.

>Cardboard stander.

>User Guide.

Design & Build Quality:-

The pair is pretty well-built. It has a unique 3D beveled shape with metallic face covers. The inner cavity reminds me of Moondrop Variations with its semi-translucent black-colored look. We have Zeos engraved on the side of both earpieces. The pair looks and feels amazing in hand. Rinko has a single air vent present right underneath the Zeos engraving on the side. The pair has a lightweight design, it sits firmly into my ears and serves me well with a comfortable fit and good isolation.

The included cable is a generic stock cable. It’s soft, has 2-pin connectors, and has a 3.5mm termination. Rinko comes with new Render Ear Tips. They are a blend of silicone and memory foam with foam filled in between the silicone tube and silicone outer layer. They are quite good and I personally like them with the Rinko.

Driving The Rinko:-

Rinko is an easy-to-drive pair, it works well enough straight out of my Sony WM1A. Heck, it’s so easy to power that it works well with my PS5 controller as well. I have used the pair extensively for gaming with my PS5. So don’t worry about driving the set, it works well off with basic sources.

Sound Impressions:-

Rinko packs a powerful and fun sound signature. It has a strong lower-end response, delivering a powerful sub-bass rumble and a strong mid-bass response. It is borderline basshead for my taste and that’s why I find it perfect for watching movies and enjoying some video games. I hooked it into my PS5 and was literally amazed by its outstanding theatrical sound feeling. It benefits from the surround sound of the PS5 and delivers an expansive soundstage with crisp bass. Lower-end is probably the highlight of the set for me. The bass is so strong that it sometimes comes over the lower mids as well, Upper mids sound clean and accurate. They have crisp clarity for vocals and instruments. Treble is also nicely done on the Rinko, it sounds clean and sibilance free.

Lower-End:-

As mentioned earlier, the Rinko has an emphasized lower-end response. It has a fast, quick, punchy lower-end response that complements genres such as hip-hop, EDM, etc. The lower-end clarity is quite refined and well-textured. Love the rumble it produces while watching movies and playing games. Personally loved watching Interstellar, the bgm sounded so lively and created a different aura with its strong lower end. I must add, this is the borderline bass response I can enjoy, anything above this would be overwhelming atleast for me.

Midrange:-

Even though the strong mid-bass reaches for the lower mids every now and then, the pair maintains a clean midrange most of the time. The instruments are well-separated, and the clarity is quite good for vocals as well. Female vocals are a bit more pronounced than male vocals. I don’t find them harsh or sibilant even at louder volumes. The midrange is pretty nicely done, although could be a bit more clean with a little more control in the lower end.

Treble:-

The Treble response is nicely done, it’s smooth, it’s detailed, it’s crisp. I won’t say that the pair has strong extension in the lower end, but it does a great job in delivering a smooth, detailed presentation with no noticeable harshness or sibilance. The pair also has good air that presents a clean staging even in busy tracks.

Soundstage, Layering, Instrument Separation, Dynamics:-

Rinko has a decently wide soundstage, with a good amount of air, the pair sounds quite open and expansive. With the Surround effect of PS5, this was just a super amazing theatrical experience. I used to play god of war Ragnarok and Horizon Zero Dawn and the experience was simply sublime. The soundstage, the surround effect, and the overall experience are pretty solid!!

Short Comparison With Simgot EA500:-

Simgot EA500 is one of my favorite sets around the 100$ price bracket. The pair sounds natural and wonderful. Here’s a short comparison between Rinko and EA500.

>Rinko has a strong lower-end, much stronger than the EA500.

>EA500 sounds more natural tonally and timbre-wise, Rinko sounds warmer.

>Rinko has a more pronounced sound, it sounds more lively and immersive.

>EA500 has a more musical presentation.

>Rinko is an IEM that produces a strong V-shape profile producing a more fun signature.

Teardown Time!!!

Okay so now being done with the review, I am going to share my teardown experience with your guys. This is my first teardown and I absolutely loved every bit of it. Just a short piece of information before I begin, I took help from a friend of mine who is proficient in modding. He has done many different earbuds and IEM mods before(like MMCX mod on earbuds, repairing mmcx/2-pin connectors, etc). So I would like to thank my dear friend for helping me out here.

Now on to the teardown, the pair opens up easily with its face cover glued onto the shell. Upon opening, the first thing we see are two wires going from the 2-pin connectors to the frequency crossover board. The frequency board is quite delicate and needed to be handled with care, it is directly connected to the drivers. The drivers here are stuck together.

There’s a big casing that houses a slightly beveled shape diaphragm with a vertical copper coil. This is I guess the dynamic driver unit. It has a single magnet attached to it on the backside. Right next to this driver towards the ear nozzle is a smaller driver unit which is stuck to the bigger casing. This is the controversial planar magnetic driver unit. This one uses a diaphragm similar to the dynamic driver unit but instead of a vertical copper coil, this one has a coil that is embedded right into the diaphragm. From my small understanding of these drivers, Planar Magnetic drivers are units that use flat diaphragms with the coil embedded into them, the same is there on this unit. There are two magnets, one on each side of this diaphragm.

Now on to my mistake here, upon trying to open the casing of the planar unit, I actually put in some extra force that broke the casing of the driver unit. So the left side of my Rinko is now planar-less lol. But I am just happy to learn this new thing. I wish to do more teardowns in the upcoming future and learn more about this. Actually teardown was interesting, it was fun doing it with a close friend. But yeah feeling sad that the unit got damaged. Now I will have to purchase a unit for PS5 lol.

Final Words:-

There are a lot of things going around for the See Audio x Z Reviews Rinko, I find the pair to have an amazing sound experience. In fact before going bad, this was the pair that I have enjoyed hours of gaming with. It’s also quite good for music, loved listening to fast genres such as hip-hop, EDM, regional Bollywood, and other regional genres as well. Rinko actually has a lively, fun sound that is pretty solid for everyday enjoyment!! Now going to get another one for me!!

General/Build/Comfort/Packaging
Rinko is SeeAudio’s first collaboration with Zeos, who’s the popular youtuber/reviewer. If you have been following Zeos for a little while, you will/should know his library’s preference, in which directly reflects to the tuning of Rinko, if you’re not a fan of his library, perhaps you may skip this review , but if you’re curious to find out how it sounds, read on!


The shell is 3D printed and very light, it has got the matte finishing with Zeos’s wording on the shell. I have no issue with the comfort throughout my listening session with Rinko which lasted roughly 3-4 hours, packaging wise, the box is the usual “waifu” printing, it came with a IEM storage case which is the same as the one found in their Yume II, three pairs of ear tips based on Zeos’s recommendation/selection. The cable is alright to me, thin and slightly prone to tangle, other than that, nothing much to comment on the packaging as it’s fairly standard.

Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far

Sound Impression
Rinko is another fun set that isn’t following the harman curve but tuned to be a fun sounding set emphasising on the bass. In terms of sound profile on stock cable and eartips, they are V shaped sounding to my ears, mids are a little recessed, bass and treble emphasised. Slight planar timbre is audible, tonality wise Rinko is leaning towards slight cool rather than warm. Note weight is somewhat lean with the stock tips.

Bass

• Bass is being emphasised here and this is Rinko’s main focus i believe, all about the bass
• Rinko’s bass is focusing more on mid bass so the punch is harder than the rumble
• Sub bass rumble has adequate rumble and transition nicely into the mid bass
• Rinko response very well to various eartips, depending on the eartips of your choice, the bass can be tight and clean to boomy, the stock tips that came with it is rather balanced

Mids

• Mids are slightly recessed but the details in this range still present themselves adequately
• Female vocal is slightly more forward compared to male vocal, texture is adequate
• Male vocal is slightly recessed, some artist’s vocal tend to be recessed while some are forward, one example when i’m listening to Michael Jackson’s track, his voice sounded recessed while Jason Mraz’s voice sounded forward
• The gain on the upper mids is evident that it favours female vocal more than male’s, if you are listening to J-Pop with female artist, you might like Rinko

Treble

• Treble is lively and energetic, but not offensive at the same time
• Detail retrieval is alright, nuances can be heard without much effort
• Non sibilant
• Good amount of air leading to good perceived sense of space

Soundstage/Imaging

• Soundstage is slightly out of your head, average depth and width, slightly lacking in terms of height
• Imaging is good, instruments can be pinpointed easily even on complex tracks such as Metallica’s Lux Aeterna, Slipknot’s People = crap!

Driveability

• Rinko is easy to drive, reaching my usual listening volume without any efforts on Apple’s Lightning Dongle
• Having said that, it does scale with source and power, source will affect the overall presentation in terms of soundstage and dynamics (based on my own listening experience)
• Feeding it with more power (Gain+ on Earmen Angel), more dynamics, mid range somehow comes forward a little, bass has better control (tighter)

Comparison (vs 7Hz’s Legato)

• In terms of tuning, both are different and the difference is day and night
• Legato has the vintage kind of sound, speaker like sound, if you have any experience with vintage speakers, you’ll understand. Rinko is more modern sounding, irrelevant but something like digital vs analog
• Rinko is mid bass focused whereas Legato is more on the sub bass which the rumble is literally felt by your jaws and transitions nicely into the mid bass
• Mids on both are slightly recessed but Legato does in better in terms of vocals for both female and male, whereas Rinko tends to favours female vocal more than male vocal
• Treble on the Rinko is more energetic compared to Legato, but both aren’t offensive nor sibilant
• Soundstage for Legato gives a different perceived feel compared to Rinko, Legato has got the atmospheric kind of staging whereas Rinko just sounds flat despite it does give you the sense of slightly out of your head
• With all that being said, it’s not to say that either one is bad but it depends on your preference

Final Thoughts
There have been too many harman target tuned IEMs in the Chi-Fi’s space, of course there are some who enjoy it and some who don't. Rinko is a refreshing addition to the market for those who don’t like harman target tuned IEMs. I don’t consider Rinko as an all rounder due to how it’s tuned, you might get away with it if you’re willing to spend some time cable rolling (That is if you believe in cable, not going to argue more and just leave it here) and tips rolling. Do I recommend Rinko? Yes, if your library mainly consists of modern music and especially jpops, if you’re into classicals and instruments, Rinko is not for you. Period.

The SeeAudio Rinko was sent to me by Hifigo in exchange for a review. No incentive was given and all the opinions are my own. The final score is also based on their value for money rather than sheer performance.

The SeeAudio Rinko IEMs is a new collaboration between SeeAudio and Z Reviews featuring 1 dynamic driver and 1 planar driver, coming in at $99.

Build and accessories:
The IEMs are built with plastic, which makes them lightweight and comfortable to wear for extended periods. Despite their plastic build, they do not feel flimsy and are likely to withstand regular use. The case that comes with them is of good quality and should protect the IEMs well.

The stock eartips, however, are not a good match for me and in my view for the IEMs themselves. Comfort aside, they caused the bass to bleed into the midrange and pushed the treble to become harsh and unpleasant.

The stock cable is lightweight but feels a bit cheap, and it remains to be seen how durable it is in the long run. However, considering the price, I'd say it's about on par with most other offerings.


Sound:
When it comes to sound quality, the SeeAudio Rinko IEMs are tuned for a fun V-shaped sound signature. Bass is definitely what is the star of the show here.

The bass on the Rinko is relatively quick and provides a satisfying amount of slam. It does make it a very fun and engaging listen, however, there is some bleeding into the midrange, which can result in a slightly muffled sound overall.

The midrange is hit or miss, they don't have a natural presentation of real instruments or vocals. They tend to add this strange sense of volume and extra layering over the instruments, which while interesting feels quite artificial and gets a bit tiring over time.

The highs on the Rinko IEMs can be a bit tricky. When paired with the right eartips, they are non-offensive and generally ride the line of being too north of neutral yet not crossing it. However, with the wrong tips (like the stock ones), they can become harsh and unpleasant. This means that finding the right tips is crucial to get an optimal treble response. I personally settled on the Acoustune AET08.


Final thoughts:
Overall, the SeeAudio Rinko IEMs offer a fun and enjoyable listening experience for those who prioritize a V-shaped sound signature over a more natural presentation. While they may not be the most accurate IEMs out there, they provide good value for the price and are a decent option for those on a budget.

Rinko Drivers:
Since there was some controversy about Rinko drivers I decided to tear down my unit to see how it looks inside. From the back you can only see the back of the dynamic driver:


Once the driver is removed, you can see that there is indeed a planar driver inside, it's very small, but definitely has a structure of a planar rather than a dynamic, which matches the patent and the explanation given by SeeAudio.




Dynamic in more detail:



Planar Diaphragm:


You can clearly see the coils run parallel to the diagram acting like traces. It's not conventional but it does achieve the same result as traces in this case.

Chubby Checkers the Twist is a fun dancing song that makes me want to dance and feel good. I remember a time when my Mom and I did a little dance in the kitchen, and it was a beautiful moment. Not to mention it's a classic perfect song chalked with mostly good memories. It’s a song that is dear to my heart. It makes me want to dance, and feel great about life.

I bought this iem with my own money. My opinions are my own. We’ll talk about the twist in the summary.

You can buy this on Amazon, and soon on Hifigo. This links are links are unaffiliated.
I was looking forward to the Rinko. It’s an affordable set. I love my z12 and think it is very strong and fun. SeeAudio has had some solid products as of late with the TANGZU X SeeAudio being a reasonable set that has a beautiful shell, and the Yume 2 which is a major benchmark for me.
Product Features

Song Choice: Tidal list here:
I listen to a wide variety of music. I pick the songs because of various reasons. But I picture myself locked away like Andy Dufresne from Shawshank blasting music and shut off from the world. It’s a blissful image.
The Marriage of Figaro -The opera song from Shawshank Redemption, terrible recording but fun and gets me in the mood to listen to music.
O mio Babino caro -This is a modern less operatic version but a song with great female vocals.
Video Rigoletto - “La donna e mobile” Sung by one of the three Tenors, great song for high-performing male vocals. Pavarotti is the greatest classic singer maybe ever. Fight me!
Iron man - The sound at the beginning is hard to make sound great, great drums, and cymbals, and if done right it feels like an old-school band.
I Will Survive (1981 recording, I like her voice, and the old vocals, the drums, and various natural instruments really make this a favorite for me.
There is a light That never goes out - Smiths ( A classic, I just love it. It’s mellow, and I can tell a lot of the tuning if this song is done right.)
Jump (I like how the sound effects are in this!)
Star Child Someone recommended this song to me, and I like how funky it sounds and has nice vocals and a mix of music and things going on.
Dicke Titten Ramstein The beginning is amazing and the bass hits hard. Great song. I love rock and metal. The German language fascinates me.
Master of Puppets: Very fast song. Helps me determine if the driver can keep up.


Shell - It’s very boring. Black shell. Overall this shell is a disappointment, as I didn’t find that it fit well, nor did I find it unique or fun.





Case- The Case is nice. Same case as the Yume 2. I have no problems with the case, and find that it adds value to the package.


Tip Selection - Its tip selection is Limited and only has 3 sets of tips included with it. I look at 20 dollar sets and find they have 6 or 7 sets with them, and I just feel this isn’t enough for a 100-dollar iem. I had to use tips from other iems, to get a good fit for myself. Not sure if this is a zeos or Seeaudio decision, but it's a very poor decision and will ruin this delightful iem for others. I am fancy, I tip rolled, but that saved this iem for me.

Comparison: I thought this was going to be a Legato, but with a Waifu and more resolving, it was not. I find it sonically a strong value comparison at this price range if you want a V-shaped iem. The Z12 will often go on sale for 135 and has an amazing cable (60 dollar cable) vs the cable in the Rinko feels about a 20 dollar cable.

Value: I don’t see a lot of value in this product. For those that really value the V-shaped iems, it could be good. Maybe you really want a v shaped iem, but can't wait for a z12 or have shortages in your country. I can’t recommend it to a friend. I couldn’t really gift it to anyone, knowing that other sets exist. Maybe giving it to Weeb friend, but I’d rather give them a cheaper iem and a few gift cards.

Sound: I just found it to be extremely shouty, and my music didn’t sound good on it. It got 3000% better when I added new tips. The stock tips didn’t work well for me at all. It was night and day.


This graph is brought to you by Hobby Talk. I find him very honest, fun, fair, and I 100% recommend him. He has a great unboxing for this if you are interested. (Unboxing here)

It was like a cheaper z12 in many ways. Cheaper cable, cheaper shell, and if you are like me those are the two most important things coming out of the box. The money in this goes to the Wafuu, not the presentation of the iem as a whole. If you want the Wafuu, or to Support Z reviews, get it. If you want an iem that sounds good with a similar V Shaped tuned, I’d go with the Z12 on sale.


Pairing: I used a Quidelix 5k and a Topping DX1 dac through an SMSL SH-8s AMP. I don’t find the pairing to matter too much, but it certainly can.

Summary- 100 is a tough point. Legato is a very fun sound that is at the same price and has a better package overall, and a much-improved sound. The package of the Legato is just smooth and fun, as is the sound. The iem is finicky, definitely try a few things before hating on this oddly packaged iem. It’s a solid pick, just not for me. I like SeeAudio, I like Zreviews, heck I even like Waifus, but I do not like this iem for music set but I could live with it. You go into an iem thinking it’s going to be great, and technical, but there is a twist: it’s just a 50-dollar set, with a waifu, in the Yume 2 box. Like an ice cream cone, it has some dark and some light. It should have added a keycap to the box, a prettier color to the iem, and had a pink cable. Lost opportunities. Now I’m going to enjoy some Icecream.

Thanks for reading. Any feedback is welcome. I’ll be posting my preference list of iems, dacs, and headphones soon. It’s in process.

SeeAudio Rinko is a bold and daring contender for the need for energetic, vibrant and bassy sound indulgences. As simple as that. Not intended to be adept at some music genres, but it does amazingly well with modern type of music that entail lots of groove and vibe.

Fairly good technically, Rinko is only held back by less than wide soundstage, while at the same time somehow managed to impart surprisingly good holographic spatial staging with precise imaging even when used to listen to Binaural type of music - even for gaming.

Get Rinko if you hgave craving for solid Midbass performances, backed by equally smooth and seismically groovy Subbass.
