TANGZU - Zero Ultima

if the iem is strictly for gaming, then comfort is king. and you don't need to spend too much for a set. im currently using tanchjim zero ultima and its so comfortable sometimes i forgot that it was there. i use it mainly for CS and League and i dont feel any disadvantages over my monarch mk2

Under 50$: Tanchjim Zero Ultima DSP, KZ Saga Under 100$: Sliivo SLA3, Letshuoer S12/Artti T10, Kiwi Ears Airoso, Under 200$: Kiwi Ears Aether It is really hard not to love these!!

All of the above have emphasized bass (more than neutral) to varying degrees, I would recommend something like Tanchjim Bunny, Tanchjim Zero Ultima, Tanchjim 1, Zero 1. (Tanchjim is the only - or one of the few - IEM companies that makes more neutral signatures at the sub 30 price range.

# Review Of The Tanchjim Zero Ultima  https://preview.redd.it/eo6s115e9ire1.png?width=4032&format=png&auto=webp&s=dfb2af20a3a78ee3908ad1a04ecb7cbb1b7bf94b **Introduction** https://preview.redd.it/o8qecq8g9ire1.png?width=4032&format=png&auto=webp&s=d2171779f6ee5d40d9c5b5421ce5750f130ba579 I recently reviewed the Tanchjim Bunny, and Tanchjim has just released another budget-friendly ear monitor. Given their reputation for producing high-quality products, I have high expectations for these as well. As I mentioned earlier, Tanchjim is a Chinese electro-acoustic company that has been manufacturing IEMs and DAC/AMPs for a long time. Since their debut, they have consistently grown their fan base. I have always experienced a premium feel and quality in their products, even their affordable options. The quality they ensure and the trust they have built with their customers are among the best I have seen. Now, let’s talk about their recent release, the Tanchjim Zero Ultima. The Zero Ultima is the successor to the Zero series they released before. I was fortunate enough to get my hands on them for review. Before we proceed further, I would like to clarify a few points. **Disclaimer** \*Since this unit tour was organised by the kindly people at Tanchjim, 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.  \*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 “Ultima.” \*I am using different ear-tips for convenience and better versatility. \*Finally, I will only evaluate the Ultima based on its performance, even though I will explain how it feels and seems physically and aesthetically. \*My evaluation is based on the standard preset that was pre-applied to the IEM. I will discuss the other types of presents in a separate section of this review. \*Please understand that all opinions expressed in this review are my personal perspective and are not intended to offend anyone’s beliefs or experiences. Therefore, I kindly request a respectful and thoughtful approach to this review, even if it differs from your viewpoint. **Specification** https://preview.redd.it/933lqpvh9ire1.png?width=4032&format=png&auto=webp&s=fe87c0189de44db80b2c4d5a90460092f7660e83 The Zero Ultima headphones feature single dynamic driver configuration. This drivers are 10mm double-chambered unit with a PU-suspended edge and a Ti-plated dome composite diaphragm. As before, they’ve incorporated the DMT technology, but this time, it’s the improved version called DMT Ultra. Unlike previous versions, these headphones have non-removable wires. They come in two variations: a 3.5mm version and a Type-C DSP version. The headphones I received feel and look similar to their predecessor, but they have a lighter tone on the shells. The comfort is excellent, and the included ear tips provide good isolation. I didn’t have any issues wearing them for extended periods. The wire used in these headphones is also improved. It consists of eight strands of 4N OFC silver-plated copper wire with a double wire core. The Ultima headphones hold their shape well when wrapped and kept in place. They’re well-built and have an inline microphone with a multi-function button. Since this is a DSP version, it also supports the TANCHJIM App, which allows users to customize the headphones according to their preferences. During testing on an Android device, I didn’t encounter any lagging or bugs. The accessories included with the headphones are six pairs of ear tips in two different types and three different sizes, along with a storage velvet bag. Moving on to the technical specifications, the impedance is 30 ohms, and the sensitivity is 123dB. The frequency response range is from 10Hz to 48kHz, with a total harmonic distortion (THD) of less than 0.05%. **Sound** https://preview.redd.it/gp6pdlqj9ire1.png?width=4032&format=png&auto=webp&s=cee728abb44e89bf26cf1c153b8fe48470533cb9 Although I’m not sure how well the standard version sounds, the DSP version is truly exceptional. It delivers a neutral and balanced sound with a sub-bass boost that can be customized using the supported app, which I’ll discuss later. I’ve heard the original zero DSP version, but I couldn’t review it, so I can’t comment on how specifically better the Ultima sounds. However, I believe the response is much clearer and transient, with well-expressed details. Now, I’m not totally familiar with the DMT technology that Tanchjim has incorporated into the driver even though I have tried another ones, but it results in a very natural-sounding response while revealing a lot of details. Considering the price point, it effectively competes with its peers, especially in the sub-$20 segment. Let’s explore the sound further to uncover more about its features.  **Treble** The primary objective of this set was to achieve a natural sound akin to the Tanchjim Bunny, but with a leaner and more airy tone. The treble section is exceptionally well-crafted, exhibiting forwardness and precise control over the notes. Honestly, the peaks around 10k and 20k contribute significantly to the sense of air and space, enhancing the resolution and dynamics of the response. The notes possess richness and clarity without sounding harsh or metallic. In fact, with such energy and a particular focus on expressing areas in the treble region, the notes tend to sound smooth and expansive. The upper treble maintains this smoothness without compromising the airiness and spaciousness. Moreover, it avoids pushing the notes forcefully, preventing any offensive characteristics from building up. The vocals feel light and fuller, while the instruments preserve the integrity of each note. On the other hand, the lower treble maintains consistency and good energy, contributing to a vividly expressive response. However, it doesn’t particularly highlight any individual nuances. Listening to tracks like “Kimi ni Koi wo Musunde” from Amagami Sisters exemplifies this well. The chimes, snares, and other instruments sound less detailed but well-controlled. The notes have good expression without sounding tinny, sibilant, or hot. Overall, the treble region presents a smooth, refined, and airy soundscape. **Mid Range** Coming to the midrange, the mix is well-forwarded but surprisingly leads to a stagey and spacious sound. The vocals and instruments are prominent in the mix, but the notes have enough space to create a lively and spacious experience. I believe the response doesn’t sound heavy or filling; instead, it sounds lean and light but doesn’t become tinny, nasal, or peaky. The upper midrange brings the most energy to the mix, which helps reduce the exposure of high octaves in the vocals and instruments. Both the vocals and instruments are well-positioned and expressive thanks to the 2k-5k boost in the mix. On the other hand, the lower midrange has enough heft and presence in the mix. It resonates with warmth and some richness, but it doesn’t deliver that fullness and wholesomeness. The vocals and instruments sound rounded and dull, but they present a clean response. Listening to tracks like Kokoronashi by Majiko sounds well-exposed and rich with good air and space. Surprisingly, the vocals have good forwardness and clarity, which leads the overall track to sound clean and revealing. Also, listening to Track Woh I Nee by Hitomi Takahashi sounds less intimate but more balanced. This helps both the vocals and the instruments sound more resolved and brings that spaciousness. However, this response takes away the revelation and fun from her vocals. Overall, the presentation of the midrange region is lively, natural, and spacious-sounding. **Bass** Now, let’s talk about the bass. I believe it’s well-controlled while maintaining that heft and warmth in the mix. The notes have good tonality and impact, but they don’t sound overly expressed. The bass has all the elements lit up across the region, but the heaviness or booming aspect isn’t noticeable. However, the heft of the notes provides a reasonable presentation that tends to give a fuller and richer sound.  The emphasis is on the sub bass region, which provides decent rumble and punch in the mix. While the articulation and texture aren’t very well-defined, the impact doesn’t feel masked but well-controlled. The mid bass has good presence, but nothing stands out in your face, which is reminiscent of how the sub bass behaves. However, the warmth and slam are very noticeable, which adds sense and depth to the notes and the overall presentation.  Listening to tracks like “Frontiers” by Awich sounds energizing and fun-sounding. The bass control helps bring the well-staged higher frequencies, whether it’s the vocals or instruments. Each element has a well-expressed presentation, so the bass doesn’t influence or emphasize any region specifically. However, when the bass hits alone, it hits hard and sounds satisfying. Also, listening to the track “RUN SAKAMOTO RUN” by VAUNDY sounds rich and dynamic. The kicks and bass sounds are well-revealed in the mix, but the impact isn’t forward, which helps keep the response sound clean and natural.  Overall, the bass region’s presentation is well-controlled, warm, and rich. **Technical Performance** https://preview.redd.it/sdgq2kll9ire1.png?width=4032&format=png&auto=webp&s=2bcb72bbbdd4761cd32ffd3edbda9d601aab0ec5 Coming to the technical aspects, I have no qualms about how the details are delivered, the layering, imaging, or the speed of the notes are. The reason is that the tonal balance absolutely creates a very well-sounding set. However, there are a few aspects that I feel are well-done. The stage sounds well-spread out with good depth and width, which helps the response sound spacious and airy. The notes have good precision, but they aren’t very clear, which takes away the sharp and articulated imaging. However, the separation is great because the distinction between the notes helps pinpoint where the sound is coming from. The resolution is fairly good. The macro details are well-expressed, but the micro nuances struggle to surface in the presentation. The attack and decay of the notes for such a response is fast, which is great because the sound is nicely resolved without making the response sound messy or degraded. **Sound Impressions**  **Tunings** Now, let’s explore the Sound EQ, arguably the most well-developed option. It offers four additional official preset tunings. Let’s delve into each of these presets in more detail. Nature Sound - When I applied the Nature preset, I noticed a significant difference in the bass and midrange. The vocals became more pronounced, and instruments sounded livelier. However, the bass felt a bit recessed, making it sound more articulate. Balanced Sound - The Balanced Sound preset strikes a leaner and clearer tone, similar to the Nature preset. It also pushes the lower treble forward in the mix. Instrument Enhancement - The Instrument Enhancement preset sounds more neutral and vibrant, with a stronger emphasis on the sub-bass. It elevates the treble and bass in the mix but makes it sound a bit thin. Additionally, it tames the midrange, which can lose its warmth and overall sound. Popular Sound - The Popular preset is the default preset with more emphasis on the bass. It gives the music a warmer and thicker sound, creating a smooth and relaxed atmosphere across the spectrum compared to the other presets. Game EQ - I tested these presets while playing Call of Duty and Genshin Impact on my mobile device. I found that the stage became more immersive, and the upper frequencies became more prominent. This made it easier to bring nuances to the surface. However, the bass still felt a bit overpowering. For me, the Balanced Sound preset worked best.  **Tracks** Millet - Anytime Anywhere Amagami Sisters - Kimi ni Koi wo Musunde Hitomi Takahashi - Woh i Nee  VAUNDY - RUN SAKAMOTO RUN Awich - Frontiers Anri - I can’t stop the loneliness  Kohana Lam - A Few Sentimental  Kohana Lam - Loving Me, Loving You Uru - Kimino Shiawasewo Uru - Kamihitoe Kujira Yumemi - Kenka Majiko - Kokoronashi Anly - Sukinishinayo  Kohama Lam - A Few Sentimental Kohana Lam - Loving Me, Loving You Miliyah - Kono Yumega Samerumade Rokudenashi - The Flame Of Love Yu-Peng Chen - A New Day with Hope   Yu-Peng Chen - Another Hopeful Tomorrow Yu-Peng Chen - For Riddles, for Wonders Valentino Khan - Satellite  Kai Wachi - Happier By Now Jawns - Erotica ISOxo - how2fly Kai Wachi - Happier By Now Weeknd - Popular YUNGBLUD - When We Die(Can We Still Get High) Bring to Horizon - Kool-Aid Middle Kids - Bend FLETCHER - Leads Me On Loathe - Aggressive Evolution The Weeknd - Save Your Tears Sigrid - Burning Bridges AURORA - Black Water Lilies AURORA - Runaway X Ambassadors - Renegades Lupe Fiasco - Words I Never Said Macklemore & Ryan Lewis - Can’t Hold Us Gotye - Somebody That I Used To Know Jay-Z - Run This Town Lady Gaga - Poker Face Lady Gaga - Just Dance Ladytron - Ghost Travis - Love Will Come Through LINKIN PARK - Somewhere I Belong DJ Shadow - Six Days (Remix) Hoobastank - The Reason Ricky Martin - I Don’t Care Tool - 7empest Tool - Vicarious A Flock Of Seagulls - Space Age Love Song Zack Hemsey - Vengeance Elton John - I’m Still Standing The Moody Blues - Nights In White Satin Micheal Sembello - Maniac  Guns N’ Roses - Sweet Child O’ Mine A.R.

I understand that many people prefer non-removable cables for various reasons, and I believe this design caters specifically to that group of audiophiles or consumers. However, the most important factor is the sound quality, and Tanchjim delivers a great sound that is both tonally and technically impressive, considering the price. Therefore, I highly recommend these IEMs from my perspective. 

your memes accurate, you'll lose positional audio cues etc in games, u should reconsider this interesting quirk. Anyways try the Tanchjim Zero Ultima DSP, it's probably good enough for CS2 or Val, not that great in BR's like Apex compared to something like the Kefine Klean or Tripowin Vivace. Everything I've said here applies to the Zero Ultima DSP too: https://www.reddit.com/r/HeadphoneAdviceIndia/s/lDT0EpYOyr

ok great, my question was related to it's app. Basically if u don't like the default tuning (which is close to JM1 or meta tuning) you can change it via presets or make ur own tuning. That tuning gets saved on the cable of the IEMs (hence my recc for DSP) That app is only available on type C DSP versions and that preset thingy works only on Android (iOS doesn't allow changing EQ thru that app). You'll just need it when you wanna change not always so it's not important. If you don't have any major issues with iems then I'd again recc u to get something like the Kefine Klean or if u have more budget, Ziigaat Lush, Kiwi Ears Astral etc

The Bunny DSP would be a few grams heavier than the Zero Ultima, both share the same internals, the change is due to the removable cable and shell design. But since you've already been burnt by one, it's better to get the Tanchjim Zero Ultima DSP, get an iem when u have spare cash or are just bored with your current earphones.

neutral-ish, get Tanchjim Zero or get the Tanchjim Zero ultima if you wanna mild bass lift or 7hz Zero which are close to IEF Neutral target

ugh I know the feeling. I just bought them and am trying to be hopeful that they'll fit when they arrive tomorrow, but my hope is dwindling. I bought the Tanchjim Zero Ultima hoping they'd fit cus every reviewer said "they're small" and they hurt for me. if they don't fit I might just give up with trying to find IEMs that seal and might get the NICEHVK EB2S Pro, since only Apple Earpods shape and Skullcandy jib shaped fit me, unless something new comes out in the next year's. but I'm losing hope :((

Tangzu Wan'er 2 — these are the powerhouse for the money. Very engaging sound. Tuning is almost perfect. Easy on ears for long sessions. Not very detailed though. Microcontrast is lacking. Macrocontrast is very good. Easy to drive off a potato thanks to 19 Ohm impedance. These DON'T scale up with more powerful source. Overall good fit, shells are light, but nozzles are stupid short. You likely would want a deeper insertion. Tip rolling is a requirement. I didn't like Tang Sancai tips supplied in the kit with this IEM. Truthear Gate — these have lower macrocobtrast, but microcontrast is better. Extremely low distortion, clean sound, punchy bass, overall the most flat, neutral tuning among those I suggest to you. Harder to drive due to 30 Ohm impedance. These DO scale up with more powerful source. Very good technicalities. Good fit. Tip rolling is the easiest among all. Tanchjim Zero Ultima — straight fit, non-detachable cable. Very clean, crystal clear tuning, good instrument layering, fast and punchy, tactile bass, ideal for classical music. Harder to drive due to 30 Ohm impedance. These DO scale up with more powerful source. Very good technicalities. Super lightweight (only 2.3 grams per shell), very thick and long nozzles for deep insertion — with narrow ear canals might not fit properly. Tip rolling is a must, though supplied silicone tips are among the best in the biz. KZ Saga Neutral — lower microcontrast, lower macrocontrast, more of a safe tuned mild V-shaped sound. Good, but not very engaging compared to those above. Easy to drive. These DON'T scale up with more powerful source, can be run off a potato. Shells are made of metal — premium quality feeling, but the heaviest of all. With some tip combinations might not fit properly and fall from ears due to improper fit and the sheer weight. Nozzle size is normal. Weight is the problem.
