TANCHJIM Bunny

Tanchjim Bunny – Showing Others How It’s Done




Preamble:

Tanchjim is no stranger to those in the know. They don’t follow the trends nor release products every time someone sneezes. The Tanchjim Oxygen, and now more recently the Origin, are products that really pushed Tanchjim into people’s mind but they have steadily, if at a slow pace, been releasing quality products since then.

The Bunny is a single dynamic based iem but with some tuning tricks implemented including an interesting rear cavity structure they call the “Acoustic Maze”, and a titanium coated pet driver.

The Bunny is priced as a budget item at under $25 CAD when I purchased it. It does come in a few flavours including one with a cable in the usual 3.5mm end and the model here in for review with a Type-C cable with built in dsp and 24bit DAC. That dsp cable allows all kinds of adjustments to the Bunny’s sound and drives up the flexibility of this iem to great heights. For this review I listened to the Bunny without the DSP cable as the quantity of adjustments are just too vast to listen to let alone review.

The Bunny is easy to drive and with the DSP cable that isn’t even an issue as the cable has a built in dac/amp as well. Even without the DSP cable the Bunny is easy to drive but tip rolling does make a difference. For my listening I went with a short stemmed wide bore tip.

PREAMBLE: That DSP Cable!

The Bunny is a well performing iem not just in of itself but with the addition of a DSP cable, an option at purchase, it becomes a flexibility beast. Not only can default frequency curves be chosen with ease but the user has access to the DSP Forum where literally dozens if not hundreds of response adjustments are just a click away. On top of all this there is a nicely functional EQ where the user can create their own sound later sharing their creation with others in that forum.

This is implemented so well by Tanchjim that it makes me wonder how come other iem manufacturers do not adopt this approach. The one negative I’ve heard is that the Android app runs much better than that which available for IOS. There have been updates since this review so this may have changed but I cannot confirm as I have only Android phones at my disposal.












SPECS:

Product Name: Tanchjim Bunny

Earphone Type: Single Dual-Chamber Dynamic Ti coated PET Driver with Waveguide

Connector: 2-pin Flat Connector

Sensitivity: 123dB/VRMS

Impedance: 30.7Ω


BUILD & FIT:

The Bunny is an attractive iem with what I will call a tastefully simple look. The shell is translucent except for the rear caps which have a metalized sticker with product branding. The Bunny is on the smaller side with a moderately prominent nozzle and should be an easy fit for most people.

The retail packaging is minimalist following the tastefully simple design of the iem. The included accessories are sparse with an additional set of tips, a branded iem bag and the dsp cable itself. The cable seems to be of good quality construction and is somewhat longer than most other stock cables I’ve seen at this price point.
A simple yet effective retail presentation as provided by Tanchjim is imho enough as the real winner here is the sound.







SOUND:

Bass:

Bass is tight and goes deep. On first listening I was surprised with the poise of the low end. Bass here has a pleasing round thickness to it which is even more evident in the mid-bass. Listening to “18th Street Lounging” by Marcus Johnson the bass had good attack with no undue overhang. “Angel” by Massive Attack continued to highlight the control of the low end. Bass energy was right where it should be even if texturing and detail is not the best I have heard but again this is a $25 set so bravo.
The bass doesn’t intrude on the midrange and remains in its role as the foundation. “Inside Stuff” by Wayman Tisdale showed how snappy the mid-bass is with good pacing and tight sound.
The bass of the Bunny is pretty darned good for a $25 iem, cheaper without the dsp cable btw.

Midrange:

The Tanchjim Bunny had a slightly forward midrange with good clarity. There is a pleasant level of detail retrieval here and even some micro-details present. The mids here have good energy but are not shouty or strident. Male vocals have added warmth which adds weight and female vocals come off as clear and detailed without sounding thin.
The Bunny’s midrange sounds natural and open allowing vocals to really capture the artists energy. The good note weight helps here and is welcome as is the quality timbre and transient handling which olny displays a touch of softness on attack. There is a controlled rise in the upper-mids that keeps harshness away while maintaining that clarity.

Treble:

The treble is again clean, open with good balance and quantities of sparkle and air. Extension is also good which helps with the unrestrained sound. Still the treble has a smooth texture to it that sounds quite pleasing.
The treble here is not tuned to call attention to itself even though it has enough energy and drive. It is actually well done. And follows the rest of the tuning of this standout iem.

IMAGING & SOUNDSTAGE:

The Tanchjim has on offer a moderately sized soundstage with decent imaging. Lateral space is well portrayed with depth and height also present but in lesser quantities. Layering and separation is not the best I have heard at just above this price range but enough to keep busier tracks sounding congested.



VERSUS:

ND Audio Planet:

The Planet has been the darling in the sub $20 iem category for some time. Mostly it deserves its mentions but still comes to the table with its own compromises.

Bass is good on either set with the Bunny sounding just that more refined. Still, this is a tossup imho. Midrange is where both iem shine and while each has a more energetic presentation, I would have to choose the bunny having greater micro-detail retrieval. Treble goes again to the Bunny having a more refined and mature treble presentation. One big difference is that the Bunny can comparatively be driven to louder volume levels still sounding clean than the Planet which tends to fall apart when pushed moderately hard.

The dark horse here is that DSP cable. Yes the Bunny is more expensive than the Planet but well worth the extra expense which may be around $10 depending on where you live. Once the flexibility that the DSP/DAC/AMP cable is included in the mix it becomes no contest.

CONCLUSION:

Tanchjim have a budget winner with the Bunny. I would say it is the perfect starter iem for those entering the iem space and in particular for those whom may not have purchased a separate source as yet intending to drive it off of a cellphone.

I would recommend springing for the version with the usb-c cable as the sound options will now be immense. If you are shopping in the ~$25USD range, seriously consider the Tanchjim Bunny. If that is above your present budget, I would say hold off and save some more until the Bunny can become a reality. Recommended.

Review Of The TANCHJIM Bunny ​

Introduction​

TANCHJIM is a company I’ve been a fan of for their single DD madness. Their IEMs, whether premium like the Hana or budget-friendly One, have always impressed me with their innovative dynamic drivers. Recently, they’ve ventured into multi-driver hybrid technology with the Kana, which received praise for its great sound performance and compact form factor.

In addition to the Kana, TANCHJIM has released the DSP versions of the Tanya and One, which are still considered budget-winners. I recently got my hands on the Tanchjim Bunny DSP, which I’m excited to share with you. Before we dive into the details, I’d like to clarify a few points.

Disclaimer​

*Since this unit tour was organised by the kindly people at TANCHJIM and Concept Kart, I am grateful to them. 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 “Bunny.”
*I am using different ear-tips for convenience and better versatility.
*Finally, I will only evaluate the Bunny based on its performance, even though I will explain how it feels and seems physically and aesthetically.
*My evaluation is based on the standard nozzles that were pre-applied to the IEM. I will discuss the other types of nozzles in a separate section of this review.

Specification​

The Bunny houses a single dynamic driver configuration with a 10mm PET titanium-coated dome diaphragm dynamic driver on each side. Given TANCHJIM's reputation for using genuine technology, they’ve implemented the same technology they used in their 4U IEM. The shells feature an Acoustic Maze Rear Cavity Structure with DMT4 ultra moving diagram technology.

Apart from the body design, the material used to make the shell’s body is similar to the 7Hz Elua, ensuring its sturdiness, especially considering the Bunny’s compact form factor. The shells’ design is highly ergonomic, almost disappearing within the ear, resulting in excellent comfort and a good seal, even for extended listening sessions.

The faceplate retains the same silverish grey paint with TANCHJIM's imprint. However, the most concerning aspect of the IEM is the introduction of two new pin connectors. These are the same 0.78mm recessed two-pin connector, but they’re unusually long, requiring the same long pins on the cable. While I was able to use different cables for analog comparison, I wouldn’t rely on the versatility and freedom to change to other aftermarket cables.

The cable included with the Bunny is excellent for a Type-C cable at this price point. It’s flexible and not prone to retaining its shape, and the material used is Litz silver-plated copper.

Regarding the DSP chip, it can decode 24-bit audio using dual DACs that support up to 96kHz sampling rates. The cable offers compatibility with various devices, including iPhones, Androids, PCs, Macs, and more. I personally tested the cable on an Android phone, iPad, and Mac, and it worked flawlessly without any issues. Now, the Bunny headphones are also compatible with their app, which allows users to achieve various EQ profiles. The app offers four more PEQ presets, which I’ll discuss later. Additionally, there’s Game EQ, which is quite helpful, and an equalizer with Q values that can be customized to suit audiophile preferences.

Other included accessories are various types and sizes of eartips and a carrying pouch.

Moving on to the technical specifications, the impedance is 30 Ohms, and the sensitivity is 123dB. The frequency response range is from 8Hz to 48kHz, and the total harmonic distortion is 0.05%.

Sound​

Bunny, as adorable as it sounds, is a hit in terms of sound quality and performance. Trust me, these are the DSP version, and they’re a literal target seeker. The reason is that these are the DSP version, and each and every tuning that comes as an official present in the app sounds phenomenal because of the variations and consistent bass boost that gives it that extra oomph and engagement.

Now, while these tunings have variations, I mean to say that each tuning sounds different. I’ll explain that later. I should also mention that I tested it with an analog cable, which tends to sound more like a Tanchjim IEM. I’ll explain that later too.

Coming back to the sound, I’ve kept the same default mode as the base of my review and will compare it to other tunings and modes as well. The Bunny’s sound is well-balanced with a really well-done midrange that’s forwarded and has the cleanest response across the spectrum compared to any other IEM in this segment. The bass elevation that glides down before 300 Hz might give an impression of a neutral sound, but the magic that Tanchjim did makes it sound warmer and richer. The midrange also has that richness and forwardness that extends to the lower treble.

Overall, even though the analog version itself is a finely tuned IEM, I’m more fascinated by the DSP version. Let’s delve deeper into the sound to find out more.

Treble​

Now, let’s talk about the treble. I’m not entirely sure if TANCHJIM was the first to tune it this way, but the dip from 9k to 12k and the subsequent rise to the 15k peak create a sense of great air and space. This allows the lower treble and upper midrange to sound more open and forward.

To be honest, I’ve been exposed to many IEMs that respond in a similar manner, and I find it to be an excellent choice, especially for an IEM in this price range. The Bunny sounds fantastic.

As mentioned earlier, the upper treble has good air and space, but it sounds more laid-back with just the right amount of presence in the mix, resulting in a relaxed and smooth response. On the other hand, the lower treble sounds forward and tonally great. It’s been a long time since I’ve heard such a consistent and composed lower treble that handles vocals and instruments exceptionally well. The vocals have a good amount of vividness, and the instruments shine with a tonally rich sound.

Listening to Marina Horiuchi’s Mizukagami no Sekai, which features upper frequencies above the normal range, I suppose, because her vocals, chimes, and cymbals have that peak in the mix. However, when listening to this track with the Bunny, it sounded balanced without subduing her vocals or the instruments.

Similarly, listening to tracks like Akuma no ko by Ai Higuchi, the vocals sounded rich but scaled well as well, and so did the instruments.

Overall, the treble region presents a smooth, relaxed, and consistent sound.

Mid Range​

Coming to the midrange, the response has a very generic forwarded response that accurately portrays both the vocals and instruments, resulting in a clean and rich sound. While it may not be the most open and airy sounding midrange, it excels in terms of tonal aspects, particularly for the midrange and the overall presentation. To be honest, the default tuning seems to align with the IEF (2020) target, and in my opinion, it sounds fantastic with the right amount of forwardness and presence that doesn’t overshadow or diminish the characteristics of other regions.

The upper midrange shares a similar synergy with the lower treble, featuring more forwarded vocals and instruments that add a touch of newfound weight and richness to the mix. Although the vocals don’t always overpower or overshadow the instruments, I still appreciate how the blend of vocals and instruments creates a natural-sounding tonality. The lower midrange has a good amount of note weight and presence that adds warmth to the upper frequencies, preventing the mix from sounding mumbly, dense, or dry.

Listening to tracks like “Everywhere” by Fleetwood Mac, the instruments and vocals blend seamlessly, with the vocals scaling well without being hindered by the instruments. The guitars sound fine and prominent, contributing to the ever-golden essence of Fleetwood Mac. Even listening to “Destination of the Journey” by Hana Hope, despite her vocals sounding a bit duller than expected, the overall experience felt more alive and helped the instruments achieve a tonally natural and prominent sound, enhancing the cinematic quality of the track.

Overall, the midrange presentation sounds rich, vivid, and natural-sounding.

Bass​

So, another fantastic aspect of the Bunny is its exceptionally well-developed bass response. Despite the tuck around 200 Hz, which should have produced a cool and detailed sound instead of warmth, the Bunny surprisingly delivers a rounded and warm mid-bass that adds depth and dynamics to the overall sound. While it lacks the slams and thickness typically found in mid-bass, the bass response is rich and wholesome. The emphasis is on the sub-bass region, which sounds deep enough to create subtle rumble in the mix. The punches and thumps have a nice weight and body to them, making the bass sound fuller. The slams and thick blows are not well-defined, but they do contribute to the overall richness and dynamism of the bass.

Since the bass is well-controlled and composed, the overall response sounds clean and rich. However, it’s important to note that this isn’t the best when it comes to bass details or texture. For instance, listening to tracks like 4eVR by Hiroyuki Sawano, the bass kicks sound impactful but doesn’t resolve quickly. The vocals are not overpowered, and even the instruments are not overshadowed during complex parts of the track. Additionally, listening to Acid Machine by The Toxic Avenger, after the first 30 seconds, sounds deep and rumbling, and it continues to sound powerful when the drop hits.

Overall, the presentation of the bass region is well-controlled, deep, and fuller sounding.

Technical Performance​

Now, to be honest, I don’t expect any IEMs in this price range to sound technically impressive. However, I do find that the details and speed of the notes lack compared to other offerings in this segment.

The stage is wide enough to sound spacious, and although the imaging isn’t the sharpest or most precise, it does sound clean. The separation between the notes is sufficient, but the distinct quality is missing, making it difficult to pinpoint where each element’s sound is coming from in the mix.

In terms of resolution, the macro details are well-surfaced, but the micro details aren’t, resulting in a softer response. The attack and decay of the notes aren’t particularly impressive, but they’re fast enough to maintain a clean and engaging sound.

Sound Impressions ​

Tunings​

Although the app itself offers a lot of customization options for tuning, including dedicated Game EQ and Sound EQ, the user can also EQ it according to their preferences while experimenting with five frequency ranges and Q values.

Regarding the Game EQ, I haven’t had the chance to play extensively to evaluate it thoroughly, but during casual use while playing Genshin Impact with the Genshin Impact tuning, I noticed that the dialogues became more prominent, and the close surroundings were more audible.

Now, let’s delve into the Sound EQ, which is arguably the most well-developed option. It boasts four additional official preset tunings. Let’s explore these presets in more detail.

Nature Sound - While comparing it to the default present, the response sounded slightly more vibrant in the lower treble, which added a bit more energy to the vocals and instruments. In my opinion, they sounded more captivating and clearer. The bass, however, felt less prominent, less warm, and more precise.

Balanced Sound - Now, the Balanced preset offers a more subdued bass response and elevated upper frequencies compared to the Nature preset and the default preset. This change resulted in a more airy and leaner sound, with the vocals sounding light and clearer, free from dense noteweight but enhanced transparency. The bass response was accurate and on point, effectively overpowering the upper frequencies as the notes struck.

Instrument Enhancement - While comparing it to the default present, the response sounded more elevated in both the bass and treble regions, making it sound more enjoyable and engaging. This resulted in the production of light and clear vocals and snappy instruments. I believe that the upper treble sounded airier and more spacious compared to the other presets. On the other hand, the bass sounds more rumbling and authoritative, with a reduced warmth. In my opinion, it kind of resembles Harman tuning.

Popular Sound - While comparing it to the default present, the only noticeable difference was the livelier vocals and the instruments and bass sounding authoritative and rumbling, similar to the Instrument Enhancement preset. However, I prefer this response as it has less warmth and a more controlled overall effect.

Analog Vs DSP​

Now, when I tried the Bunny with a 3.5mm terminated cable, I could relate to the TANCHJIM's in-house sound tuning. While comparing it to the DSP, I noticed that the response sounded more organic and natural, with a warm and clear vocal tone. This response has a mid-centric sound, featuring impressive slams, thick drops, and a relaxed upper treble.

Conclusion​

The Bunny is a must-have for anyone looking for a balanced sound within a DSP and app support. It allows you to adjust the sound quality and even switch to an analog configuration for a price less than 25 USD. The app offers a wide range of options and customizable settings to suit your individual preferences. TANCHJIM's reputation for quality and the promising sound quality you can expect make the Bunny a standout choice. The only downside I can think of is the elongated connectors and pins on the IEMs and cable. While this doesn’t pose a significant issue, it’s worth noting that not all two-pin cables will be compatible with the IEMs.

Specs And Driver Configuration

Before starting the review, I want to thank Hifigo for sending this iem iem for a review

Unboxing Experience and Accessories Package

There is one word that comes to mind when it comes to the unboxing experience and accessories package of bunny “Adequate”. Nothing spectacular or underwhelming. The external sleeving has the image of the iem and has text explaining the technology that is inside this iem.



Removing this sleeve shows the box with the tanchjim logo, opening that shows iems and all the accessories kept in one place.



The accessories provided are decent. Things provided in the box are 1. 3.5mm cable with mic 2. two types of eartips, large bore and small bore 3. carry pouch.

The cable provided is a big letdown for me, I know it's 20 dollars but still, this cable is not adequate for the price. It's the similar cable to the tanchjim one, very thin, fragile and plasticy feeling. Another issue with this cable is that it becomes significantly stiffer over a few months.



The eartips provided are good they provide very good comfort and seal.



One aspect of the accessories package that I really appreciate is the inclusion of a carry pouch, which is a thoughtful addition, as many IEMs don't typically include one in the box.



Design and Build Quality

The overall design and shape are very similar to the Tanchjim 4u, which means it's very small and ergonomically designed. The whole shell is made of transparent plastic, which looks very cool but does not feel as good, I would say build quality is very similar to the 7hz zero 2, not the worst but not excellent either, it's sufficient for the price.



One cool thing about the design is that you can see the acoustic maze structure on the side which adds to to coolness factor. It features a matte metal faceplate, which is better than the tanchjim 4u’s shiny faceplate that picks up scratches as soon as you unbox it.



Fit and Comfort

The fit and comfort of this iem are one of its highlights, I can wear this iem for hours on end without any issues. The shell is small and lightweight, contributing to an exceptional fit and outstanding comfort. The nozzle lip is on the larger side but the overall nozzle is not that thick so it doesn’t pose any issues.



They fit very flush in the ear so sleeping while wearing them is not an issue. It passes my sleep test as well. The isolation provided is decent not the best but it's sufficient for the price.

Sources Used

For my sound testing, I did most of my testing on samsung dongle and it powered it beautifully. For some fun I put some tracks on the Chord Mojo 2, I did see much improvement so if you have a phone with a 3.5mm jack or an entry level dongle like apple or samsung dongle that will be more than enough for this item.



Frequency Response

I used the provided narrow bore tips and final e-type tips for my listening. The analog version has a warm neutral tuning.



Bass

The quality is very good for the price. It is a very satisfying bass. The bass tuning is mid bass over sub bass but that does not mean the sub bass is not present or lacking. The sub bass rumble and texture are very good. The mid bass thump is also good. Overall I have no complaints with the bass on this iem. This type of bass tuning can play almost all popular genres very well. There is one thing I want to mention if you are coming from more mass market earphones that have a lot of bass, then you can find the bass amount to be lacking as per your taste, bunny is not a basshead set.

Mids

The mids on this IEM are beautifully tuned. As the bass transitions smoothly from the sub-bass to the lower mids, it imparts a slight warmth to the lower mids, giving them good heft and body that makes the sound feel very natural. The upper mids are tuned to provide an excellent extension to instruments and vocals without sounding overly sharp or shouty. The presence region has just the right amount of energy to deliver good clarity and definition to the vocals. Instruments come across as very natural on this set, while both male and female vocals sound excellent. Male vocals have impressive heft and body, while female vocals carry a husky character with very good weight. However, if you prefer your female vocals to sound slightly leaner, this IEM might not be the best fit for your preferences.

Treble

The treble is decent overall, is it is he best treble in this segment, I would say no. Mid treble is at the perfect level, so it does not sharp, there is a big dip in the 10k region which is typical of this price range after that the treble picks back up in the air region. There is a peak in the region that adds airiness and slightly increases the micro detail pickup. If the 10k dip was a little filled out the detail retrieval performance would have been even better. So, overall treble performance is very similar to other sets in its class.

Detail retrieval and Technical Performance

The detail retrieval and technical performance are very good for the price. The macro detail pick is good but the micro detail pickup is excellent for the price. I think this is one of the top sets in its class when it comes to detail retrieval. But it's not night and day difference, you have to listen and compare other the iems with it side by side to hear the difference in detail retrieval. But it's there. The technical performance is very good the stage has decent width, and the imaging and instrument separation are also good, but keep your expectations in check this is a 20-dollar set.

Bunny 3.5mm Analog vs Bunny type-C DSP (Tuning Comparison)

I didn’t receive the Bunny DSP so I EQed the Bunny to bunny USB stock eq and popular to test the tuning of the DSP version.



The USB stock sound of Bunny is what I would call neutral, there is a drastic reduction in the mid-bass, and now the bass profile is more of a tuck than a slope. The bass is majorly sub bass focused, and lower mids became far cleaner sounding, but people who like their vocals to be on the weight side will find this tuning to dry sounding. There is a slight reduction in the mid-treble to better balance the less bass. Overall I liked this tuning but found the bass to be on the too lean side. Now to my favourite tuning the popular preset. This fixes all the issues of the stock DSP profile, this profile has a very healthy sub-bass shelf, so the bass is still clean and separated sounding but now it is more fuller and more rumbly sounding, the lower mids see no change, there is a slight boost on the upper mids to balance out the bass, seeing this type of tuning in a 21 dollar iem is a surprise, this is the power of DSP, in my case EQ. I hope this tuning comparison between the Bunny and Bunny DSP was helpful.

Conclusion



Tanchjim has released an excellent set for the 20-dollar price range, I really enjoyed both the stock profile and popular DSP preset. Bunny provides very good tuning, detail retrieval, and technical performance for the price. Though it is not without fault, the stock cable is just not it, Tanchjim if you are seeing this please improve the cable that is provided with your iems. I know it's 20 dollars, but still, many iems at this price have better cables like gate, waner, chu 2, etc. Overall Bunny is in my top recommendation when it comes to sound under 2000 rupees or 20 dollars.

What's up, Doc!

~~Bugs Bunny, a major Looney Toon character.


Bunnies commonly known as Rabbits are small herbivore mammals belonging to the order, Lagromorphs which also includes hares and pikas. They are known for their sexual activity in nature that they can reproduce quickly and a preyed animal in the wild. Bunnies/Rabbits are known for their docile and adorable nature that makes them a good pet but in some cultures, they are considered as a livestock for meat source. Rabbits have strong symbolism in both Western and Eastern folklore as that it is one of the main celestial animals in a Chinese Zodiac and also there are some personalities that strongly associated with rabbits like Chang'e, the Moon Goddess in Chinese Mythology and Kaguya-hime of the Tale of the Bamboo Cutter.



We in the audio enthusiast community know the reputation of the TANCHJIM as an audio company as they are quite exceptional in producing some of the best entry-level sets in the market. Their old model, the Oxygen, is still among one of my favourite single DDs of all time on how I truly impress its well-meticulous tuning and excellent build quality.



What I have here right now is their latest entry-level set, The TANCHJIM BUNNY and this model is somewhat the affordable version of their previous model, the TANCHJIM 4U in which I rate it highly in my review due to its neutral tuning and an option to switch other types of tonal profiles by adjusting its screw-style mechanism via small philips screw driver. Like the aforementioned 4U, this one also equipped a similar single dynamic driver technology that TANCHJIM self-developed.



The dynamic driver that was implemented here is a DMT4 Ultra which has some modification from the original DMT4 that was used on the 4U. While its retains a 10mm dual-chambered design but it uses a different material on its diaphragm as it uses a composite diaphragm made of a PET material reinforced with titanium coating that offers better tensile strength and elasticity that delivers rich bass and a clear and detailed vocals and instruments in a full range sound quality. Aside from the driver, it also implemented an acoustic maze structure on its acoustic chamber to improve the overall quality of its bass response.



The driver was then encapsulated in a bunny-inspired shape profile made of a hypoallergenic-grade polycarbonate plastic shell structure along with a brushed stainless steel faceplate in a tear drop shape. The shells are quite compact and offer an ergonomic fitting that will be versatile to all ear sizes. Like all TANCHJIM sets, it uses a 0.78mm bi-pin connector as its interlocking mechanism.




When it comes with fitting and comfort, the BUNNY with its bunny-inspired form factor on its shell design, offers a relatively snuggly fitting into my lugholes that gives a passive noise isolation that is able to block some external noises coming from the outside surroundings.



The stock cable of the BUNNY is somewhat decent for its price which is an oxygen-free silver-plated copper in a parallel structure with a 3.5mm termination plug on its end. It also has a HD mic with a single button for single command. The cable is quite pliable and has some resistance from entanglement and offers a very minimal amount of microphonics. There's a type-C with DSP chip option where you can choose it upon ordering this product.



As product packaging, TANCHJIM BUNNY is fairly loaded with quantifying amounts of accessories given it was packed in a compact packaging box.



Here are the following contents we can find inside of its packaging box:

• Pair of TANCHJIM BUNNY IEM transducers.
• Stock cable
• Felt cloth carrying pouch
• Three (3) pairs of balanced bore silicone ear tips in different standard sizes.
• Three (3) pairs of wide bore silicone ear tips in different standard sizes.
• Paperwork like an instruction manual and a postcard.

Regarding power scaling, the BUNNY is on the side which needs a bit better power output to amplify it optimally. A proper power output shows that this set is capable of delivering a full sound quality with good dynamics on it. So pairing it with headphone amp dongles, DAPs or other devices that could deliver a better audio output would be a better choice for this set.



When it comes to tonality, the BUNNY has a mild U-shaped sound signature which highlights the elevation both on both the low and high frequency for the overall tonal profile.


LOWS/BASS:

The bass quality of this set is rather balanced as both sub bass and mid bass have a presence on the low frequency region. With a balanced bass presentation, it delivers a punchy, incisive and clean bass response.

Sub bass can be fairly felt as it has some grumbling and reverberation that were generated coming from certain instruments like synthesisers, drum machines, and from low tuned bass guitars and double-basses. The mid bass has an adequate texture enough to give an ample note weight on some bass-clef instruments.

The bass guitars have a resonant and enough weight on their sound while the double-basses sound broad yet sustaining, bass kick drums have a thudding and resonant sound on every stroke in its drum head. On male vocals like bass and bass-baritones, while they have the resonant and sufficient depth, they don't sound dense and as it is lacking that dark timbre that makes them sound less dusky and wool-like.


MIDRANGE:

While the midrange presentation of this one is quite a bit recessed on its overall sound quality, it still presents a pretty balanced and natural sound on vocals and instruments as it has a neutral with sufficient warmth, a bit transparent and a tidy sound.

The male vocals have an ample note weight as the baritones sound smooth and warm, tenors have a clear and full sound on their vocals and countertenors have those tender and emotive characteristics for their distinctive falsetto to have that captivating and pleasant sound. Meanwhile on female vocals, contraltos have some plushiness and smoky sound although not that heavy and husky, mezzo-sopranos have that velvety and an ample fullness with enough gleam on their vocals, and then sopranos have a clear and creamy sound characteristics that suits well with dramatic and lyric types of sopranos.

When it comes to instruments, on string ones, guitars sound more balanced and sort of midrange-y, violins have a sweet and sensuous sound on every motion on its bowstrings and cellos sound mellow, gentle and sweet. As for woodwinds, concert flutes sound mellow while piccolos have a rather soft and delicate sound rather than intense and brilliant, clarinets sound gentle and a bit rounded and saxophones sound velvety and mild. The brass instruments like the trumpets, trombones and horns, they sound rounded, full and dull respectively as they will sound pretty well on a bit accentuated upper mids. On percussive instruments, snare drums have a precise and clear sound, tom-toms have a resonant sound with some warmth on it, field drums have a sonorous sound and kettledrums sound mellow and dull. Pianos apparently have a more balanced to mellow tone as it has that resonant, sweet and rounded sound although I find it sometimes a bit dull and flat in my liking.


HIGHS/TREBLE:

To determine its treble quality, the treble response is on the balanced and smoother side as it doesn't have those jarring peaks on the upper-mids and presence treble section but it will sound a bit dull and veiled to treble heads. It has a decent clarity and definition for vocals and attack of instruments and there’s not a hint of sibilance, shrill or tinniness.

On the brilliance part, it has a modest airy extension with less intensity on its sparkle. Cymbals sound lustrous and undulating while hi-hats sound a bit soughing on its distinctive chick-y sound, glockenspiels sound less shimmering and celestas have a soft and mellow sound.


SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

The BUNNY projects a decently above average sound/speaker stage as it has at least an above par width on its lateral span, and also good height reach and depth as it will be perceived as fairly spacious head room within my aural perception.

Stereo imaging of this one is rather a linear, two-dimensional stereo presentation with fairly decent layering and separation in which I can pinpoint the placement of instruments and vocals in a soundscape.

Driver coherency of this one is quite excellent of how it performs with its nimble transient response on executing a fast bass speed and crispiness of the overall sound quality without any distortion issues at all.

On its resolution capabilities, I consider this one as fairly resolving as it shows some solidity on it macro-dynamics while its micro-detail retrieval appears to be less sharper but a bit blunted on highlighting some nuances and subtleties from an audio track like vocal ends, reverb tails and distinctive notation attacks from instruments.


PEER COMPARISONS:

SIVGA QUE

• The QUE has a single dynamic driver on its composite shell chassis made of wood and metal alloy.
• It has a beryllium-coated diaphragm on its 10mm dynamic driver.
• It has a better stock cable and carrying case.
• The sound signature of this one has a U-shaped tonal profile that if it will be compared to the BUNNY, it has more vigorous and impactful bass response, more recessed and energetic midrange presentation and bright and airy treble response.
• On technical capabilities, it has an above-average sound speaker stage with good depth, well-layered soundscape and a sharp definition on micro-detail retrieval.

7HZ G1

• Like the BUNNY, it has a single dynamic driver encased in a solid metal alloy shell casing.
• It implemented a 10mm dynamic driver with DLC-coating on its composite diaphragm.
• It has a bit better carrying case and probably stock cable.
• This one has a U-shaped sound profile that aligns with Harman-style of tuning which makes this set sounds more sub bass-focused with less mid bass texture, lean and yet midrange and bright and airy treble response compared to BUNNY.
• The technical performance of this set is somewhat its strongest assets as it has a marginally above average sound stage size, good layering and separation on its stereo imaging and sharper definition on its micro-detail retrieval.

TRIPOWIN VIVACE

• TRIPOWIN’s latest entry-level single driver with a shell chassis consisting of composite materials.
• It uses a 10mm dynamic driver with a PET diaphragm.
• It doesn't have any carrying case for storage with a rather average stock cable similar to BUNNY’s albeit different build and materials.
• The VIVACE has a U-shaped sound profile with balanced-warmish tonality on them that it has sub bass-focused bass response that sounds rumbly and precise, adequately warm and well-balanced midrange and a bit energetic yet smooth treble response.
• On technical capabilities, the VIVACE is quite an average in terms of overall technical performance as it has fairly intimate soundstage size, a typical linear two-dimensional stereo imaging with decent layering and separation, and a less sharper definition on its micro-detail retrieval.

TANCHJIM once again prove themselves that despite a very competitive audio market, they are able to release a competitive and affordable entry-level set that sounds closer to an almost neutral-sounding that is quite uncommon in the portable audio market segment. It is noticeable that they still need some polishing touch on its tuning like clarity and resolution, and also for this type of tuning would not give that engaging factor to a casual listener who wants a more coloured and fun sounding tonality on their listening session.

But despite its flaws, the BUNNY is overall a good product with good build quality, smaller shape profile and a tuning that most sets could have and usually price at around US$100/80 and I can still recommend this one.

TANCHJIM BUNNY is now available on HIFIGO, I just provided a non-affiliated link below.

P.S.

I am not affiliated to TANCHJIM nor receive any monetary incentives and financial gains as they provide me a review unit for an exchange of factual and sincere feedback from yours truly.

Once again, I would like to send my gratitude to MS. HERMINE QIU & KERWIN WU of HIFIGO for providing this review unit. I truly appreciate his generosity and trust towards me and other reviewers.

General/Packaging/Build/Comfort
Tanchjim is back with another banger this time with Bunny, a single dynamic driver featuring “maze structure” or rather helmholtz resonator, which is quite rare for an IEM at this pricing. There are two variants of Bunny, one is the standard 3.5mm and another one is with the Type C’s cable, which is priced just slightly higher at 25$. The packaging is minimal but it doesn't look cheap at all, the presentation is very good especially at this asking price. Inside the box, there's the IEM itself, the cable and eartips. Stock cables look very good and it does the job well.
The fit and comfort is very good, the shell does not have any rough edges that protrudes and causes discomfort, i have been wearing the unit for some long listening sessions and i did not have any discomfort with it.

Gears used for this review

• Fiio JM21
• iPod Classic 4
• Dunu DTC 480
• Aune S9c Pro Reference Dac Amp
• Tanchjim Bunny Stock Cable with Stock Eartips

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
Bunny 2 is quite a fun sounding set compared to Zero.There are some who find that the Zero is too flat but there are also certain audiences who like the neutrality that Zero offers. I would say the Bunny’s sound profile is slightly V-Shaped, but what I do notice is that the Bunny does require some power in order to fully “Sing”. Overall timbre is very natural and note weights are neither too thin or thick



Bass

• Bass quality is good on the Bunny and has adequate quantity for me
• The sub bass does rumble when it’s called for but nowhere near basshead territory
• Mid bass has good slam and punch to it and it is really really very commendable for its price point
• Good texture and speed as it is evident on tracks like Slipknot’s People = crap, it’s keeping up and doesn’t sound muddy at all, it doesn’t even bleed into the mids
• One thing to note, as i mentioned above, it does requires quite a bit of power to get a good bass response, as with most IEMs with the “Maze Structure”, otherwise, what you are getting is just weak and thin bass
• This is for 3.5mm version, i do not have the Type C’s version, but i am sure that Tanchjim has taken that into consideration and the Type C’s version is able to extract everybit of performance out of the Bunny

Mids

• The mids has good note weight to me when listening to Imperial March by Wiener Philharmoniker, John Williams
• Vocal positioning is slightly recessed but not to the point where it sounded very far away from you
• Both male and female vocal has pleasant texture and weight to the vocals, they’re not thin sounding
• Upper mids are safe and nowhere near shouty

Treble

• Treble has got enough energy and never harsh nor sibilant, not overly smooth and certainly not peaky
• Extension is alright for the asking price
• Nothing much to comment here as the implementation is generally good
• Something’s got to give right? Well, detail retrieval is average i would say, not really a con but rather nitpicking

Soundstage/Imaging
Soundstage is slightly out of your head, good depth and height for the asking price.
Imaging is good with the ability to pinpoint instruments easily

Driveability
Bunny is not hard to drive but of course when you feed it with a better source, it does perform better. It scales quite well with power i would say. Entry level/budget dongles are not really recommended but you can try if it fits your use case or sound preference.

Comparison (7Hz Zero 2)

• More bass quantity and slightly more focused on mid bass, Bunny has slightly better sub bass response
• Bunny has slightly better treble response, in terms of quantity and extension, whereas Zero 2’s treble is more on the smoother side of the spectrum
• Timbre quality and note weight are more or less on par for both
• Slightly smaller soundstage compared to Bunny
• Overall, the Zero 2 and Bunny are quite close in terms of sonic performance, edging out each other slightly from the bass, treble, mids as well as technicalities, it all boils down to fit and comfort which i think most will also be looking at, Zero 2 has shorter nozzle, while Bunny’s nozzle is slightly longer than Zero 2, i personally have no issue with the fit for both, but i have seen some complained about the short nozzle of Zero 2 causing it to not seal/fit well

Final Thoughts
Not gonna say much but if someone asks me if they should get Tanchjim’s Bunny as their first starter IEM or even a daily driver? I’m more than happy to tell them yes, even seasoned audiophiles will like this I'm sure. I for one like them, I take em out and just put them on with my DAP and listen to music without caring much for technicalities or seeking to hear every single detail in that particular track. It is just something that I wear and I listen to music and completely indulge myself into it. An easy rec for Tanchjim Bunny in terms of sound and high price performance ratio.

Disclaimer
Please note that I am not an audiophile, and this review does not delve into the technical aspects of the IEMs. My impressions are based on my personal preferences, and others may have different experiences with this product. I also have a very limited experience with audio products so please take this review with a grain of salt.

The Tanchjim Bunny was sent to me to review by Mic Audio Store over on TikTok.

Price: 19 USD

Part 1: General Product Details

Package Inclusions:

• IEM shells & cable
• Carry pouch
• 6 pairs of eartips (3 pairs wide-bore tips, 3 pairs standard tips)
• A waifu postcard may or may not be included

The IEM Shells

• The shells are made of a completely transparent resin, showcasing the internal components and drivers.
• The metallic faceplates have “Tanchjim” and “Bunny” have printed on each iem in white ink.
• These are very light, weighing 3.2g only.
• The form factor seems to be similar to the Tanchjim 4U

The Cable

• There are two choices when you order the Bunny, a 3.5mm version and a Type-C DSP version. I have the former.
• These are non-braided, but rather are like 2 strands stuck together and wrapped with a flexible plastic material. I don’t mind these, they are easy to wind and unwind but I think they will develop “memory” over time so mind how you wind them.

The Carrying Pouch

• The pouch is a small drawstring bag made of a gray suede fabric. It has the Tanchjim logo debossed in the center of one face of the pouch.

Part 2: Subjective review

General Usage Impressions

• The eartips have a certain smell to them out of the packaging. Letting them air out helped reduce the smell
• I did not recieve the waifu postcard with my review unit, but it should be included for those who buy this pair.
• The fit of the earpieces are comfortable and the included eartips also give a good seal.

Sound Impressions

• There’s an acceptable amount of bass power and bass rumble, which can be felt listening to Otonoke by Creepy Nuts.
• In Falling by Jin and Taka the vocals are a little thin, feels like there’s not much power in them. This is the same for Moongazing by Kenshi Yonezu as well as the intro of Answers by Masayoshi Soken.
• Female vocals however ring clear and vibrant. In ebb and flow by Ray and Hero too by Kyoka Jiro and Chrissy Costanza, their voices are crisp, well-defined, and carry an engaging energy that sits forward in the mix.
• Musical instruments on the treble also ring clear. Piano and violin instrumentals are a treat to listen to
• Soundstage is narrow to average at best. Resolution is acceptable.
• The impression I have of this set points to mean that this set, while it can be considered a generalist IEM, excels best when listening to KPOP and JPOP music
• For gaming it does its job fine. I put the Bunny through a few games of Overwatch 2 and Marvel Rivals and the directional audio as well as imaging are accurate enough.

Final Thoughts
The Tanchjim Bunny is a great budget earphone. And while it's a good all-rounder IEM set, I think it shines best for people who like music with clear and strong female vocals, like K-pop and J-pop.
It doesn’t have the deepest bass or the widest sound, but it’s well-balanced and clear. It’s comfortable to wear for a long time and looks really nice.
If you want a good-sounding, stylish earphone that’s easy on your wallet, the Tanchjim Bunny is a great starting choice.

-------

Quick Disclaimer: I am a beginner who just casually listens to music without thinking much about it and this is my sixth review. I’m still fairly new to these new terminologies but with the help of the wonderful people in my community, I was able to get better with using the right terminologies and know more about the technical aspects of audio.

Another thing worth mentioning is that these IEMs have not yet been released to the public so prices might be different from others but there are no technical changes once it’s up for grabs. And lastly, all these thoughts and opinions are my own, I did not read any reviews prior to making this and since this is technically like a pre-release IEM, there were no reviews to begin with(as of this review)

The gear I am using for this review has been narrowed down to my Laptop and the TANCHJIM Bunny. The reason behind this one is because I was sent a DSP version instead of a 3.5mm version which limited my testing since I do not have any Type C devices except an adapter.

A HUGE thanks to Mike Liu and Mic Audio Store over at TikTok for sending these to me for an honest review. This is my first ever sponsored review and I look forward to more reviews in the future!

So let’s begin.

TANCHJIM is an audio equipment company that has been around since 2015, they’re known for their popular IEMs such as the Hana and Oxygen. They focus on the build quality and technical aspects of their audio equipment while offering them at a much cheaper price so definitely check them out if this is your first time to hear about them.

The TANCHJIM Bunny IEMs are rumored to be within the 15$ to 20$ range but that might differ once it is fully released; these are super lightweight with a plastic shell and metal faceplate while having a single dynamic driver inside. Of course, single dynamic drivers are mostly known for their balanced/neutral tuning but these IEMs offer so much more than that. It won’t blow your mind because of how insanely good these are but they’re perfect for an entry level IEMs while still packing some great sound quality.

---

UNBOXING EXPERIENCE


The unboxing experience reminds me a lot when I first bought my first sets of IEMs namely the Salnotes Zero and Tangzu Wan’er, it’s pretty simple and not much overkill with the packing. The front of the packaging already shows the design of the Bunny IEMs as well as an indicator for the 0.78mm Long Pins and the DMT4(Dual Magnetic Driver Technology 4 Ultra), I have no idea what this is but I’m guessing this is the next level dynamic driver.

There are two versions of this, one has a 3.5mm jack and a DSP Type C which has a built in DAC. One key note about these IEMs is that they come with a proprietary app that can be used to tune these IEMs to your personal liking, unfortunately the app is only available on Android via an .apk, so iOS users will have to sit this one out.

Flipping the box over you get to see a diagram showcasing the build structure of the IEMs, the specifications are also indicated but do not come in a bullet form but instead are indicated through sentences. There is no graph present which is to be expected already.

Removing the sleeve and lifting up the box, you are presented with the following:

• The BUNNY IEMs with the cable attached to them.
• 2 Bags of ear tips(1 bag for wide-bore and 1 bag for balanced)
• Instruction Manual
• Felt Carrying Pouch

It’s really nice to see how some of these budget IEMs come with their own carrying case/pouch, really thoughtful and not something you’d always expect. Not to mention that the ear tips that come with it even have an XS size for those with tiny ear holes.

---

FIRST IMPRESSIONS

My first impression on these IEMs is that these are balanced/neutral IEMs, it should be expected a bit given that this has a single dynamic driver, the tonality is bright meaning that it is focused on vocals and instruments, perfect for music genres such as KPOP, electronic, rock and so on… I also noticed a bit of harshness on the treble which was a bit of a down factor for me.

The mid-range on these is decent, instruments are not as refined as those that I have auditioned before namely DZ4, S08, Cloud and ButterFly 61T, those IEMs are in a different level BUT the Bunny is within the same category as the Tangzu Wan’er. Sound staging, imaging and depth were also decent, I would say that these are leaning more to the narrow side. There was a bit of shimmer present when it comes to instrument strums and strikes particularly in the drums but it quickly faded away.

Lastly the bass, again this is a balanced/neutral IEM so obviously the bass here is definitely lacking, there is a tiny bit of mid-bass while no signs of sub-bass rumbling.

AFTER BURN-IN IMPRESSIONS

After using the Bunny IEMs for an extended amount of time, I did notice that there was a difference in tonality. It used to be bright but after a while it became bright and warm. For those who don’t know, the warm tonality has a bit of sound surrounding the bass. This means that the sound staging imaging and depth have been increased and shifted from being narrow to slightly holographic.

The mid-range also improved after the burn-in as instruments are more refined and have better separation. While it is still not on par with the DZ4, it is significantly better than the Wan’er. The shimmer was also better before the burn-in, the duration of the strums and strikes were a bit longer giving the listening experience a more natural feeling.

And now the bass, since the IEMs now have a warm tonality, it is expected that there is a bit more bass to it. The mid-bass has gotten a bit more punchier and there was a slight rumble in the sub-bass; while this definitely does not shake your eardrums, it completes the listening experience of having low frequencies present. A bass head like me is pleased but still not satisfied as I prefer having a bit more punch and rumble even if the music is not fit for it.

Overall, these IEMs should be part of the budget list of 2024, for a rumored price between 15$ to 20$, it is a perfect entry level IEMs or a gift for the holidays for someone who would want to upgrade or get another pair. The design is also its unique feature as it does look like a bunny. It is also recommended to give these IEMs some burn-in to really get that dynamic driver working to its full potential.

Blup blup 𓆟 and happy listening!

Enjoy some pics I took at the XP Cafe

The Tanchjim Bunny is a bold attempt at creating an engaging, old-school V-shaped IEM with modern twists. While it doesn’t achieve perfection, its strengths make it a unique choice, especially for gaming or cinematic use.

Strengths
Detailed Midrange: The Bunny’s midrange clarity stands out, offering exceptional vocal reproduction and a textured, nuanced presentation, quite unusual for the price point.

Low-End Depth: The upper bass and low mids provide satisfying weight and definition, delivering warmth and body to the sound.

Expansive Soundstage: The Bunny excels in soundstage width, creating a spacious listening experience that enhances immersion, especially for non-musical content.

Drawbacks
Weak Sub-Bass: While the low end is textured, it lacks deep bass rumble, leaving some tracks feeling incomplete.

Underpowered Treble: High frequencies feel tinny and underdeveloped, falling short of a crisp or sparkling finish.

Overemphasized Upper Mids: A sharp peak in this region detracts from an otherwise okay tonal balance, leaning towards a forward presentation that risks fatigue over longer listening sessions.

Imaging Limitations: The wide soundstage comes at the expense of precise imaging, with transitions from left to right lacking refinement.

Tuning Characteristics
The Bunny delivers an old-school closed V-shape tuning, reminiscent of the OG KZ ZS10 Pro. It emphasizes early upper mids and upper bass, masking sub-bass and high treble weaknesses with a forward, energetic presentation. This retro-inspired tuning gives the Bunny its distinctive character but limits its versatility across diverse genres or use cases.

Tip Rolling for Improved Performance
A significant upgrade in performance comes with the Spinfit CP100 tips, which enhance sub-bass impact and overall tonal balance. The tips refine the Bunny’s low end, making it more dynamic and better suited for those seeking deeper bass extension without compromising the existing strengths.

Best Use Cases
The Bunny thrives in gaming and cinematic applications, where its wide soundstage and impactful low mids enhance immersion. It is less suited for music-focused or general multimedia use due to its tonal imbalances and limited treble finesse. However, for its price, it offers great value when paired with these specific use cases.

Final Verdict
The Tanchjim Bunny is an ambitious entry-level IEM that successfully carves out a niche with its old-school tuning and expansive soundstage. While not the most versatile monitor, its strengths in gaming and cinematic enjoyment make it a compelling choice for buyers on a budget. With some tip rolling, the Bunny delivers excellent performance for those seeking a wide, immersive sound experience with a touch of nostalgic charm.
