The Tansio Mirai TSMR3 sport 3 Balanced Armature drivers per side and are tuneable by 3 switches for a total of 7 configurations. And I know of no better way to start a review of the Tansio Mirai TSMR3 than with a personal anecdote.

When I first bought the TSMR3, it came in what Tansio Mirai claimed to be a “balanced positive mode”. (0,1,0 with “1” indicating the presence of a switch flipped on, and “0” otherwise) Now whatever “balanced positive mode” was supposed to mean, I have and had no idea, but I found them to be mid-forward in nature. There was a distinct lack of bass, and the forward midrange was too fatiguing for my liking.

With that, I looked towards their recommended “low frequency strong mode” (1,0,0). Wow, that’s some hard-hitting bass in comparison! But with a pullback on the midrange, sibilance on the TSMR3 became quite apparent. Messaging a friend who had owned the TSMR 3, he recommended a (1,1,1) configuration, which perplexed me given that it wasn’t listed on the Handbook as a recommended setting, but I gave it a try anyway.

As a result, it’s now the default setting I use and will use throughout this review, given that it’s sufficiently bassy, only occasionally sibilant, and represents the most balanced configuration in my opinion.

The anecdote serves to show the sheer versatility of the TSMR 3 – make no mistake, the tuning system works, and a suitable sound signature should be attainable for most people on these IEMs. While such a gimmick would be wholly undesirable should the drivers inside the TSMR 3 produce mediocre sound, I’m pleased to report that the TSMR3 absolutely dazzles as a whole package.

Also, in case you’re curious and wondering why 3 binary switches yield 7 combinations in total, it’s because (0,0,0) is unlistenable, producing sound akin to a concert inside a trashcan.

Packaging and Accessories

The TSMR 3 arrived in what I can only most flatteringly describe as an “unassuming cardboard box”. Upon opening, all the accessories are nested within the included case which is surprisingly large.

Accessories provided include:

– A large black case, and small pleather pouch

– Earphone Cleaning Tool

-Myriad pairs of silicone tips

-A small metal tuning tool

That’s a very decent haul accessory haul, though I personally find the case way too large, and small pleather pouches incapable of properly protecting my gear.

Build Quality, Fit, Comfort and Isolation

Build Quality (8.5/10): The TSMR 3 is built out of sturdy, thick resin shells, and look like they’d be able to weather a fair bit of abuse. The tuning system has a negative profile, ensuring it cannot be easily damaged.

My preferred 2-pin cable configuration is present here, and feel sturdy upon cable insertion or detachment. Speaking of the cable, though, it’s a relatively cheap braided one that can be bought at maybe $10 on sites like Taobao, and they’re a little too thin for my liking. The black, metal, L-Shaped jack it terminates into, however, is a different story, and inspires a great deal of confidence.

Fit and Comfort (7.5/10): They’re quite comfortable, until they’re not. They’re a little large, so wearing them for long periods of time might cause some discomfort, but for short listening sessions, they stay comfortably in my ears without significant issue. They don’t sit flush in my ears like the BGVP DM6, but rather, stick out of my ears a little.

Isolation (8/10): A lack of vents on the TSMR 3 make isolation great, but not amazing. More than sufficient for daily commutes on the tube/subway/train wherever you’re from.


Overall, the sound signature of the TSMR 3 is can be said to be balanced with an upper-mid focus.

Bass (6.5/10): The subbass of the TSMR 3 is capable, going significantly deeper than, say the BGVP DM6 on tracks like Lorde’s “Royals”. There is still a noticeable roll-off in the lower registers, and there is still a lack of significantly powerful rumble.

In the midbass, the TSMR 3 doesn’t quite have the weight and slam of a capable dynamic driver, and can feel a little lacking on punch on certain tracks. It does however retain relatively natural decay, though maybe just decaying a little too fast for my liking.

Overall though, the bass is fairly detailed, but texture is on the average side. While the bass on the TSMR 3 might satisfy most folks, bassheads should look elsewhere, as they’re always going to being missing that extra bit of impact.

Mids (7.5/10): The lower mids feel slightly recessed compared to their upper counterpart, but they do shine fairly well on their own. A little more body on male vocals such as Ed Sheeran’s opening verses on “One” is desired, but the velvety texture of his voice comes across clean and clear, along with loads of detail. The same conclusion could be reached on Michael Buble’s tracks, such as “Dream a little dream of me”.

The upper mids of the TSMR 3 are mighty impressive, and the real star of the show. There’s a peak in this region, but the TSMR 3 does well to strike a good balance, being energetic while remaining relatively unfatiguing. Female vocals are forward, sweet and detailed on tracks such as Clean Bandit and Zara Larsson’s “Symphony”, avoiding an overly nasal presnetaiton which many sets with upper mid peaks have fallen prey to.

Highs (6.5/10): The peak found in the upper mids of the TSMR 3 also carries over to the lower treble. The region is slightly boosted, and can occasionally be found to be very slightly sibilant. It is, however, very detailed, with instruments such as cymbals crashes on Rage Against the Machine’s “Killing in the Name” a pleasure to listen to given their excellent decay and air.

The transition from lower to upper treble is smooth and easy to listen to due to the dearth of any sudden or harsh peaks. The very top end of the TSMR 3 experiences a roll-off, so trebleheads would be disappointed. It’s something I would appreciate though, given my personal preference for darker signatures.

Soundstage, Imaging, Seperation and Timbre (8/10): The soundstage of the TSMR 3 is wide, but it’s really the depth that is most impressive, providing for an extremely immersive listening experience. Imaging on TSMR 3 is excellent, as showcased in Dire Straits’ “Sultans of Swing”, with each instrument occupying their own unique positions across the soundscape. Seperation on complicated tracks like “Little Talks” by Of Monsters’ and Men left more to be desired, however. Timbre on the TSMR 3 is great, with instruments and vocals sounding natural, though maybe occasionally sounding a little thin on the upper mid/lower treble regions.

*Special Note on the tuning switches: In essence, the switches provide a bass, mid and treble boost respectively, though when used in combination with one another create varying signatures.*


A sonic chameleon, the Tansio Mirai TSMR 3 complements a capable sound signature with a well implemented tuning system, ensuring that a large majority of the population can and will enjoy the TSMR 3. They’re the whole package, with no obvious flaws, and an easy to recommend entry level set for budding audiophiles.
Pros: Sound- Balanced tuning, clarity with smooth treble
Tuning switches- Balanced Mode 020 and Bass Mode 100 sound fantastic
Great build quality, fit and finish
Very comfortable over long periods

About the Company & IEM-
Tansio Mirai, as I’ve come across online, is a company run by a university student who makes these IEMs by hand. It’s amazing how talented people are at such young ages. They have a nice range of options starting from a 3 BA configuration going up to a 12 BA flagship. Looking at their prices and components used, they have a very high quality to price ratio. Earlier the downside was that you could only order on Taobao, which can be a very confusing experience for international buyers as everything is in Chinese and even Google Translate fails to translate all the text since a lot of it is image based.

Luckily for International buyers, Penon is now stocking the TSMR-3 and you can now order yours from the link below. There are two color options, transparent clear and transparent black.

TSMR-3 has 3 Knowles Balanced Armatures (1 Knowles ED 29689 & 2 CI low frequency drivers) with 3 crossover, 7 tuning switches, 12 frequency division components on both sides which all use high quality USA and Japan components. You can alter the bass, mids and highs with the combination of three switches. The Switch combination chart for your reference is provided below.

Mode 1:

100: Bass enhancement mode
120: Mixed tuning

Mode 2:
020: All balanced mode
103: Mixed tuning

Mode 3:
003: Mid-treble enhancement mode
023: Mixed tuning
123: Mixed tuning (lowest impedance)

Included in the box-
TSMR-3, 0.78mm 2-pin cable, hard disk carry case, 2 packets with an assortment of ear tips, 1 pouch, 1 cleaning tool and 1 switch changing tool.

The IEMs came in an extremely simple cardboard box packaging. I don’t really care much about the packaging till they arrive safely as my main concentration is on the quality of the IEMs.


Build Quality-
The shells of the TSMR-3 are made up of resin. The fit and finish is amongst the best I've seen in this price range. The seam isn't visible and there aren't any bubbles in the body. The nozzle is finished in matte so that the eartips don't slip away as it isn't a traditional lip design. Also, the nozzles are colored blue and red to denote the left and right side.

Sadly, the 2-pin cable doesn't look all that premium. Some cheaper IEMs like iBasso IT01 have better cables. But this isn’t a deal breaker because the cable isn't microphonic, feels decently rugged and does its job well. Also, nowadays a lot of very well-made cables can be bought for very little money.

IMG_20181227_153838.jpg IMG_20181227_153939.jpg IMG_20181227_154022.jpg

Fit and Comfort- I prefer over the ear design IEMs. I get the most comfortable fit with the TSMR-3 out of all my IEMs in this price range. The shells are light and well-shaped for my ears. They also block quite a lot of outside noise, so much that my friends got tired of ringing my house bell while I was listening to music on the TSMR-3 and had to call me on my phone to let me know.

Mind you, the nozzles are a little bigger than the average 5mm and not all tips available in the market will fit them. You need wide bore and longer bore length ear tips for them to fit nicely on the nozzles but the TSMR-3 already comes with a couple of them and they are also easily available in the market.


I must say that from the first listen, I was very comfortable with the sound signature in the default 020 mode. Most of my review is with the default mode 020 but there were some instances where switching modes really made a difference.

Checking with a test signal, these IEMs are capable of producing lows from 20 Hz. The sub-bass and mid bass are both presented with a neutral presentation. The bass notes are well defined and you can hear every deep note clearly. It’s fast, tight and has good punch.

Since the low frequency driver is a BA, the bass is well controlled and not as massive as how DD bass can be. But here is the exciting part. Move to mode 100 and here comes the SLAM! Listening to Karnivool’s Simple Boy and Goliath which are bass heavy rock tracks were a delight in Mode 100. Not being over dramatic but I jumped out of the seat in excitement. For a BA bass, it has good slam and note clarity.

Mids- Again the mids are well tuned towards a neutral presentation. They sound natural with good detail. Instruments have good separation with a natural timbre. Singer-songwriter and vocals based music like Ed Sheeran's, sounds particularly good. Vocals have a nice smooth texture and don’t get lost in a busy mix. Kick and snare are also well presented in the center and have good slam. Drums in songs like I Am Giant’s Transmission sound so good that it gets awkward when I’m out in the public and can’t resist the temptation to air drum. Jokes aside, people who like good mids presentation with good separation are really going to enjoy this IEM.

Since a nice Knowles balanced armature has been tasked with treble duties as well, the treble is clear and well extended. It is smooth, never gets harsh and the sibilant region of 8 kHz is well controlled. High pitched vocals, falsettos and cymbals sound nice and clean without sibilance. If you like more treble, which according to me isn’t really needed, you can always switch to Mode 3 for more of it. Treble is well extended in the air region as well and there are no particular intrusive frequency boosts which makes for an enjoyable and fatigue free listening experience.

Soundstage, Imaging and Separation-
Soundstage, imaging and separation are all good. In modern music's busy mixes with guitars, synths, bass, drums and percussion, you’ll be able to hear everything clearly and positioned in the image accurately. The reverb trail on Gavin James’ Always sounds beautiful and deep which is a good indicator of depth. Switchfoot’s Meant to Live intro’s hard panned guitars have good imaging and whole mix is portrayed with good separation. Soundstage is of the kind which makes you feel a ‘part of the band’ rather than an ‘audience member in the crowd’.


BGVP DM6 ($199)- TSMR-3 has better sub bass and mid bass presentation. It’s more fun, engaging and impactful. As I explained before, Mode 100 sounds really good for bass. TSMR-3 also has better bass note definition and clarity. Mids on the TSMR-3 are more refined and have better separation. Snare, vocals as well as acoustic timbre tonality sounds better on the TSMR-3. I don’t know if its just my DM6 unit but there is a little wide hump in the mid-bass to lower mids which makes them sound a bit cluttered in that region. Treble again sounds more refined, smooth and without any harshness on the TSMR-3. Though the DM6 has good treble extension but the peak in the 6-8 kHz sibilant region makes falsetto based Gavin James’ song Always, very sibilant. As for imaging and soundstage, both are good at it but TSMR3 has better separation.

iBasso IT03 ($249)- IT03 is a v-shaped sounding hybrid with a dynamic driver in charge of the bass. As a result, IT03’s bass is boosted and more prominent whereas TSMR-3 has a more neutral bass response. Both, IT03 and TSMR-3 (in Mode 100) can satisfy majority of the bass needs. Mids on the IT03 are scooped owing to the v-shaped signature whereas TMSR-3 has a natural mid frequency presentation. IT03 is brighter but the TSMR-3 has smoother treble extension. Both have good wide soundstages where IT03 has a little more width and TSMR-3 has a bit more depth. IT03 and TSMR-3 are very different from each other and meant for different audiences. If you like a nice V-shaped signature, go for the IT03 and if you like a flatter response, neutral presentation, choose the TSMR-3.

Conclusion- In the default 020 mode, everything sounds well balanced and natural. I've taken them for a spin across various genres and everything sounds exactly like how I expect it to. Mode 100 and 120 make the bass even more engaging and fun. In the end, TSMR-3 is well built, fits comfortably and has a balanced, enjoyable musical tuning with an added advantage of tuning switches, which give you the ability to alter the sound slightly to your liking.

Great review indeed. How about a comparo with Moondrop Kanas Pro Edition?
@mRaaghava Thank you! With the balanced mode of the TSMR 3, in short, the overall sound of Kanas Pro is cleaner but it is less rich than the TSMR 3. The bass and midrange of TSMR 3 are fuller. Treble articulation on the Kanas Pro has higher precision.
