Tansio Mirai (abbreviated TSMR) is an experienced yet rather obscure IEM company from China that began as an OEM maker in 2014 and began making their own IEM once they were confident enough about their experience.

This is how they present themself:

‘’The brand name is taken from the Tang and Song dynasties when the ancient Chinese economy and culture were at their peak.

"未来" represents a vision for the continuation of prosperity in the past and the present.
TANSIO MIRAI started to develop earphone-related products in 2014, and later established Beijing Tang Song Boyuan Technology Co., LTD in 2016.
Earphone design and production team from Guangzhou Academy of Fine Arts, adhering to the high level of production technology, improve the custom earphone aesthetic standards.
After several years of precipitation, the company began to officially release custom earphones and universal mold earphones in 2018. To sound first, to beauty for constant.
We adhere to the use of high-quality materials, gradually accumulate and develop more mature and more characteristic tunings, and constantly surpass ourselves.
For the future, we will continue to innovate and forge ahead to find our own positioning and brand characteristics.’’

I get aware of this company when I read positive reception of their highest end IEM which are the RGB (9BA+8EST) and Halo (8BA+4EST), yet I was wrongly thinking TSMR only specialize in kilobuck earphones and don’t follow much their newer release until the TSMR X begin to be praise everywhere….then some weeks after the Feat come in and I decide to contact Penon to review them.

Why? Because of the special dual dynamic driver it uses which is something i never heard and was the main selling point for the X in my case. It’s no mystery I'm a bass lover and find this frequency range very hard to achieve properly, i mean when we seek the sweet spot between bass quality and quantity.

So when I read this for the X:

‘’Hollow coaxial structure dual dynamic driver, the rear driver through the hollow’s hole complete sounding, and produce a certain push-pull force on the front driver, not only to ensure sufficient energy, but also to provide a richer sense of layer, so that the quality and quantity of low frequency are greatly improved.’’

I was already sold. The Penon Quattro already infected me with dual DD dual push bass promise so it was time to try an ‘’entry level’’ set that can please basshead that don’t want to feel too guilty in terms of tonal balance….

Priced 240$, the Feat promise exactly that and use ‘’2 x 8mm dynamic driver hollow coaxial carbon element diaphragm for low + 2 x Knowles balanced armature for mid & high’’ for delivering a rich bassy and lush musicality that will both be fun, versatile, and i hope fatigue free.

Let's see in this review if the Feat will Fit your needs and is worth being called a ‘’must have’’ for bass lovers with limited budget.



The Feat is made of thick resin plastic that feels invincible. Size while chunky is quite small for a 4 drivers IEM. It has a triangular shape without a hard angle. Plastic is soft and smooth and half transparent so you can admire what's hidden in Feat belly.Front of the shell has an ergonomic shape based on ear modeling, then the nozzle is super short and a bit large. This mean the Feat are solely meant to be inserted with shallow fit, so for those using only deep fit IEM and using foam ear tips, it might be a con. For me, it’s a plus since I'm a ‘’shallow fit’’ kinda guy.


On top we have a 2 pin connector that isn’t recessed, this means most 2pin cable will match it too.

The back plate has a very beautiful sparkly blue lining pattern ,which is a joy to look at under light.

All in all, excellent construction and very comfortable (shallow!) fit.

When it comes to cable quality, we are very spoiled here yet…there is no specification or info about cable material. Which seem very similar to the Simgot LC7 cable I adore but LC7 seem to have more cores and thicker strand (18awg).
This one is very thick and smooth, it’s surely a high purity OFC silver plated cable too, and you can select the plug you want (2.5mm bal, 3.5mm se or 4.4mm bal).
Excellent cable that is very welcome.

The packaging comes in a small minimalist but good looking box. Apart from the excellent cable, we have 6 pairs of silicone eartips and an IEM case I find ridiculously small since the cable dont even fit in. That's the only drawback I can pinpoint, so this mini case might have other use potential for when you have very minimal space.

All in all, great construction, great cable, OK accessories.



Let’s begin by saying that the TSMR Feat spell on me is very hard to break so I need to always report the review, even after 2 weeks of daily listen….I have numerous attempts that solve into: drowning in their luscious musicality. These are just so musical and immersive within a lush and bassy warm musicality that you drown in it slowly, like in honey…

This means it’s not a clinical or analytical set, otherwise, my emotional side wouldn’t be as invested, making cerebral perception easier for critical listening.

This doesn’t mean these are underwhelming technically, if you can accept it’s warm DNA, as well as important yet well balanced juicy bass boost.

And it’s where all begin, their no doubt the dual coaxial DD bass is what captivate and wow the listener at first, even anti basshead couldn’t say these are bad in bass department, just perhaps not to their taste in balance dominancy cohabiting within a coherent, lush and lively way. Yes, we are in this guilty pleasure solace where bass quality and quantity embrace each other in a flexible impactful dynamic, with colorful dense timbre.

But let’s begin with the overall TONALITY: these are warm and darkish W shapes in balance, with a focus on bass and treble. They are smooth and buttery, with thick bass and vocals. These are not for treble heads, nor those that want thin mids with brighten presence. The dynamic is muscular and hefty, but not edgy. Upper mids sensitive will not endure shouty or sibilance even if mids are lively and loud, we aren’t in overly safe territory since both bass and mids jump at the listener and wanna kiss you.

Then if I summarize technicalities, it would be about attack impact which is speedy and weighty, but not edgy. The transient of note is fast in a multi layered way that doesn't boost readability of imaging, it’s no monitor, it’s colored. The bass is ‘oddly’’ the technical beast here, due to fast attack with great transient flexibility that digs very deep while treble goes roll off after 10 kHz due to 2 balanced armature limitations as well as damping of their energy spike. Feat is an IEM that favors lower harmonics yet can cover the full range of most instruments and vocalists.

If you love BASS, the Feat will be an intense love story for sure. We have both sub and mids bass boost here, with a wide and elastic attack impact and release. These are basshead, but not hardcore hard hitting one since the sound pressure of impact isn’t poking eardrum, as well, it’s not a V shape that would make the mids recessed, it warms them but with coherency due to multi drivers use.
The bass boost is about 12db, I don't care about graphs but I know this. 10 db bass boost rarely gets the basshead tag, while 20db is hardcore basshead to me and can create hearing fatigue and even headache which isn’t the case as noted here.
The sub bass rumble is dense, vibrant and deep, it can extract bass line presence envelope gloriously in a way it favors the flesh and tone before the texture grain and presence cutting. It’s not a one tone oomph we get with the Feat, it’s the whole tone being amplified in physical presence.
The cello sound superb, you just can’t unfocus from it, sure if this have to cohabit with piano it might stole the attention of it due to lush grunt and round forward presence of low end, yet, you will be able to follow the piano too due to an organic layering that is effortless.
Then when it comes to kick drum, digital one will have more weight and bulbous presence envelope than acoustic one which will have a darkened edge and mellower impact, yet, kick never sounds thin or plain flat like more U shape bassy IEM we find nowadays.
This is a very flexible bass response that keep its vibrant air density down to it's sub bass extension, bass line are both physical and well rounded, while these go big slam it don't create hard hitting sound pressure due to slightly warmed and tamed mid bass. Flavorfull bass like this is very rare, especially when we got a thick but not muddy presentation.

Keywords: muscular, dense, thick vibrant rumble sustain, bodied bass line, elastic attack, natural warm tone, balanced basshead.

This means the MIDS are warm and forwards, with slightly dark definition sharpness and dense and lush timbre.
It’s not the kinda mids that have an edgy attack stroke that will make the violin abrasive and bright, nor improve the resolution of their attack timing and energy. In this case, slower cello fit more like a glove tonaly wise, and feel less forced in coloration.
The mids benefit more wind instrument and vocals than tapping and slapping attack lead, the sustain in attack chain is warmed and this densifies the timbre of both male and female vocalist. Unless the highest pitch soprano, the naturalness of the vocal is boosted by lushness and has more tone info than anharmonic texture info. This is all sugar for their ears, which explains how addictive these can become. This means that articulation-intelligibility of words will not be sharpened in vowels too, this can make some lyrics less easy to follow if speedy singing but even as a french speaker i don’t really struggle (unless bad recording).
Vocals are sibilance and shouting free, the dynamic is frontal and lively, it jumps at the listener in a sensual way not a bully all upper mids boost way. You melt into it and presence is wide due to lower register being complete, the air flow in vibrancy, breathy vocal like Sabrina Claudio don’t get the breathy texture extracted wrongly, which happen often with harman tuned IEM, i can’t handle her vocal which sound boxy, thin and plain artificial with so much IEM! Yet, I find the one to get kissed by, Sabrina being a paroxysm of sensuality, she deserves gourmet lushness that the Feat delivers in plentiness.
These are intimate mids you mix in, so in that regard it might lack crisp openness for some even if layering is on top of chunky bass.
Thin mids lover should look somewhere else.
The Feat render piano in dense, weighty but mellow way, saxo in a warm full of flowing air way that add dynamic to the blowing flow, trumpet never sound screamy nor boxy top, which again is quite rare with IEMs unless super flattened in dynamic release.
Ok i will say it, to my ears the Feat got the mids the Quattro should have gone for, which means the pinna gain and upper mids boost isn’t overly safe, it does have minimal crunch to it, the sound envelope of the instrument isn’t too liquid nor too flat.
We are in gourmet mid range territory, where the word refinement will be adequate for those who love tone richness that fulfill the soul not just the mind with forced sound info.

Keywords: Lush, fully bodied, natural timbre, wide vocal and instrument presence, softed definition edge without going too dark, weighty note impact, warmed resolution, not crisp nor airy, thin and recessed.

Now when it comes to TREBLE, this isn't the prime focus of the Feat and we are in slightly dark territory, without the dullness and crumpled spatiality that would come with it if it was a single DD, BA or planar for ex.
It’s mostly smooth with just a hint of upper mids and treble crunchiness that permit attack to not go sloppy or definition don’t go too abstract.
Think about Final E3K-E4K-E5K kind of highs and you’ll have a good idea of the type of sugary refinement we get with Feat highs.
We have the high instrument tone and presence material without the hard edge to cut up their presence crisply. It’s not the type of highs that will permit you to follow ultra fast percussion with bat-like ears. Lazy ears will not be happy with the Feat, as noted it’s not for treble head, but the percussions are there and well layered, they never go splashy nor spiky.
Roll off it is and the sidekick of this is lack of sparkle and brilliance as well as perceivable air.
But this means you're never distracted from bass and mids too, you suck up in music, you don’t chase for micro details butterflies nor don’t get attacked by unpleasant higns mosquitoes with the Feat that highlights all goodness of music for long listening pleasure without ear damage risk.
Would I wish the Feat to add 2EST or 2 extra BA for treble extension? Yes, but I would still want mid treble to be smooth and polished like it is.

Keywords: smooth, refined, creamy, full and natural percussion, minimal crunch and rolled off ultra highs.

When it come to SOUNDSTAGE, the Feat offer very wide and tall 3D holographic spatiality, with a sense of openness that is vibrant with moving air that affect cleaness of background and sense of depth due to center stage and mids instruments-vocal putting their substance forwards.

This means Feat is no master of IMAGING even if the spacious multi layering is well articulated. Those sound layers are thick and not fully transparent, you can’t perceive air silence between them, this makes the tuning more cohesive in a round meaty way that avoids messy macro muteness due to great technical performance of its 4 drivers.


Side Notes

This is one of those IEM with both low impedance and sensitivity, while they aren't that hard to drive they benefit from clean powerfull source, something like Fiio KA17 is a great match. So anything with 4vrms and 100mW or above should be enough. These aren't sensitive to the point of creating distortion and the DD love extra power push to be properly bass and reach sub bass naturaly.

Then the ear tips is a bit capricious too since the nozzle is very short, i suggest short wide bore to don't block the 2 nozzle hole and get fully extended soundstage.

Then for cable, yes these can get warmer or brighter depending which one you pair it with, but I feel the stock one is enough and don't justify urgent uprgade need. If so, my suggestion would be Simgot LC7 since it's the one I always finish to use (better imaging and macro dynamic).




OK, this is a bit of an unfair fight but I can't resist comparing two of my fav IEMs when it comes to bassy lush musicality with capable technical performance.

The Feat is warmer, darker and bassier and tonality is a bit more W shape in the sense we have rounder thicker mid bass punch and thicker fuller mids, it makes the OH700 feel more U shape and a notch thinner in high bass-lower mids which are less warm.

Feat bass performance is superior, it’s more agile and flexible in extension and fuller in tone, cello sound more natural too, rumble has more tactility, its slam is less scooped in roundness and hit harder. OH700 is a notch more texture for electric bass but doesn't offer as fleshy presence, it doesn’t color as much the mids and without bass boost the presentation is notably cleaner and less bleedy.

Mids are darker and thicker with the Feat, timbre is softer, more buttery and both male and female vocal are smoother, less boosted in texture and higher harmonic, more liquid and less well define in presence enveloppe, intelligibility is superior with OH700 as well as resolution and we have more air between layers, timbre being lusher with the Feat i prefer more laid back and fuller in tone vocals but miss the cleaner readability of OH700.

Treble is where the OH700 is evidently superior, it extends further, offers crisper snappier and more brilliant highs as well as greater sound info. It has more air on top too. Macro dynamic is more edgy and note transient as more accent in attack lead and less foggy sustain.

The Soundstage is wider and deeper with the OH700, while taller and more holographic with the Feat, you feel in the middle of music, part of it more.

Imaging is average with both but the OH700 can keep its readability better in busy track, 2BA vs 6BA here sure give the advantage to OH700 in terms of positioning accuracy.

All in all, I love both and can only conclude that these 2 complement each other very well, OH700 being a slight upgrade in technical performance but not offering as lush and natural vocals.

VS Unique Melody 3DT (3DD-400$)

The 3DT is notably brighter, more energetic in treble and less bassy.

The bass is thinner, more textured and defined in presence, has faster and sharper punch but with less weight, sub bass is notably more rolled off and just about presence, complete opposite of Feat bass which is chunkier, rumbler, weighter and lusher. Their zero bleed into mids with the 3DT, kick drum being notably brighter and free of resonance or impact release.

Mids are brighter and harsher, more prompt to fatigue and sibilance, upper mids are sharper, vocals are thinner and more noisy in texture. Mids sound like monitors with boosted treble, clarity is superior than darker lusher and more mid centric Feat.

Treble is way more aggressive and spiky, its more edgy and percussions aren’t missing a hit unlike more foggy highs of Feat, instrument has more bite from violin to guitar to snare, cymbals can go ear damaging splashy so highs are leaner and safer with darker Feat but not as captivating and well define.

Soundstage is wider and taller with Feat, while it’s deeper and more ‘’mono’’ with 3DT.

Imaging is superior with 3DT, positioning is crisper and less mushy.

All in all, 3DT sounds more analytical and technical but has inferior bass response and notably harsher tonal balance, for me Feat musicality is sky highs superior.



Ok let's begin by sayin I adore those so much i press 5 stars first then....feel a bit guilty and with a pinch of hearth conclude these are 4.5/5 when we give great importance to technical performance.

Why? Because these aren't technical or analytical sounding at all, it's not the tuning goal here, in term of plain musical enjoyment ill give those a 6/5 in fact!

But does it mean they are bad in that aspect? Absolutely not, because the Feat achieve a very bassy musicality without veiling or recessing the mids, it achieve a fully rounded macro dynamic that feel cohesively warm and not mushy in it's articulation. Thanks to hybrid configuration that permit to layer sound properly as well as mids that are energic enough to open their wide presence and kiss the listener with cello, saxo or vocalist goodness.

Yet this is a very gourmand Feast here, i mean Feat.

There nothing I love more than melting in sweet music free of agressive upper mids or treble spike, free of noisy boosted texture grain, free of thin detached bass, just...well, free and wild like a natural beast running under the warm sun.

Either your a basshead, bass lover, warm balanced tuning lover or even lush mid centric tuning lover, you'll find something addictively tasty in Feat musicality.

Music should embrace you, not punch you in they face or poke you in they eyes....and the Feat wanna spoil music lover first and fore most, it trigger more emotional and physical response than cerebral detachement and jsut for that it worth:

Very Highly Recommended for warm tuning lover!


PS: I want to thanks Penon for sending me this review sample after my request. As always, their zero $ involved and I don't resell my IEM neither (this is why Comparisons part have pic by the way). I'm irreprocheable of any bias but my own subjective audio opinions and impressions.

You can order the TSMR Feat for 240$ here (check ChiFI Love group, since i might try to get coupon code for the members, these worth it since it's logical upgrade to something like ISN H40!):

Fantastic photos and great article, thanks for sharing!
I really appreciate your reviews! The way you focus on musicality is brilliant. Since I mainly listen to classical music, would you say these are also suitable for that genre? I purchased the Artti 10 based on your recommendation, and they've been excellent for classical music. Many thanks!

brother the TSMR-X

TSMR-FEAT is the newest IEM from Tansio MIrai that brings something new and unexpected from the group. What you guys have to understand is that these guys are not really known for their bass driven sound. Nope if there is one trait for the group that stands out. That would be how they tune for trebles more so than the low end. Tansio Mirais sound tuning has traditionally been about the trebles and all the sound aspects that audiophiles enjoy with a full bored treble end. However they have always had good to excellent bass for their IEMs as well.

The TSMR-FEAT uses dual knowles BAs for its mids and trebles and dual 8mm carbon coaxial dynamics for its bass performance. The first thing I noticed beyond just how good looking these IEMs are is that they no longer use the Tansio Mirais switch system they have used on every single IEM they have made till now.

However this one signature they have used on the TSMR-FEAT happens to be a good one. In true hybrid fashion. We get the technical leaning precision and imaging associated with BA performance but then they added these outstanding coaxial dynamics to handle its bass performance.

The new FEAT will be sold at a lower price bracket than the TSMR-X. Safe to say as these are not exactly going for a better TSMR-X. What's interesting here is that I can hear the family resemblance to the TSMR-X especially on the bass boost 1 switch but there are a few aspects about the FEAT that are different.

Folks that have never heard a Tansio Mirai IEM before and you're a bass fan, these might be a good place to start. For the guys that own the TSMR-X do you need to get this one? Nope not really. Well that is unless you feel the need to get a more simpler bass driven version of the TSMR-X for out and about. And or your just a huge fan of what Tansio Mirai has been cooking up lately and have to have them all.

The TSMR-FEAT is all about giving the listener a true hybrid presentation. It's not masking the fact that it uses BAs for its clean detailed sound presentation or its push pull coaxial dynamics for its brawny bass end. This is a sound that maximizes what both types of drivers are good at. On one end you get a sound bore connected to the dual BA that throws out the mids to trebles the other sound tube is connected directly to dual 8 mm carbon dynamics that are stacked on top of each other in dual push pull configuration. It looks similar to what the TSMR-X is using for bass with a vent out the back of the shells. I can see tonal and cohesive purists not liking this one as Tansio Mirai is not hiding a damn thing when it comes to what both these types of drivers are doing for the sound here.

One firm warning, the bass end was more than brawny out of the box. It's clearly a sub bass focused sound but had a burly presentation out of the box I was not ready for. I can literally hear the bass end tighten and is starting to get better definition now that I have had 50 hours or so of burn in. The bass end on these definitely needs a good run in before they start to sound correct.

What is interesting about these is that this is Tansio Mirais idea of a fun tuning. For folks that make IEMs dedicated for audiophiles that means these are bassy but also has a clean detailed sound tuning out of the box. Its clarity is on point but is nowhere near what the prior Tansio Mirai Sands or the Lands represent. These are the least treble focused Tansio Mirais to date actually. That bit of extra treble energy Tansio is known for is now focused toward the bass end. The balancing of the treble and the mids are closer to the recent TSMR-X more than anything they have brought out in the past. Where the sound cranks up a notch or two is in the bass department.

Its bass end is burly, rumbly with a slower realistic sub bass decay. They sound like subwoofers in the ears. These are pushing at least 8 dbs if not a bit more so toward the lowest of the lows. It is interesting when I first heard the bass end I could have sworn it was closer to the 1 switch on the TSMR-X but the more I listen to these they are actually tuned a bit like the reference 2 switch than the 1. It might be due to how impactful the sub bass is but it's not shy about bringing the bass. Let me put it that way. I can hear the air pushing the subs to new depths on this one. Before you ask. I don't feel the quality of the bass on the FEAT is up there with the TSMR-X. It has a slightly darker bass tonal character in comparison. Which provides a different contrast from what the TSMR-X bass end is doing. On the opposite end they don't have the same treble emphasis or the extension of the TSMR-X either. Which again brings a bit more attention to the low notes on this one. The good news there is that its bass is cleanly separated from the mids performance, helped out by utilizing a single bass bore to the ears separated from the mids and treble BA.

Let's get this out of the way. Really the TSMR-X is at a different level vs the FEAT in SQ and its overall presentation. The FEAT is priced at $239 for a reason. However it does have its own SQ.

Where the sound is engaging for the TSMR-X the FEAT has this going for it as well. But I can see a bit of a different scenario for the FEAT. TSMR-X is more of a home IEM, more refined and boutique in the way it presents sound. The FEAT on the other hand makes for a perfect out and about companion. Reason why I say this. The bass end on these are wild! Its sub bass performance you have to hear to believe. It is remarkable just how much these sound like real subwoofers. Its passive isolation is above average as well which helps you hear all of its glorious rumbly bass.

The contrast of clean well imaged mids and treble with a full bored sub woofer like sound profile is what the TSMR-FEAT is about. If any of you guys owned the old GR07 back in the day. These are like a modern day version of those but actually has dimensional qualities to the sound profile and not so flat sounding like the GR07. None of the treble spikes associated with that monitor as well..This one is a much more refined experience in comparison.

Audiophile bass IEM? You bet. In a way the FEAT is focusing its sound on some of the better aspects of what the TSMR-X does but using less drivers. Sound is not as airy or as spacious as the TSMR-X, they don't have the same type of sound separation or the detail level either, you have to expect that as it is using 2 less BAs for its sound.. However it shares some similar aspects like balancing, and shares similar tonal qualities. What is surprising here is it retains much of that holographic sound presentation of the TSMR-X, which in turn allows the same ability to be able to pull off accurate acoustic and orchestral listening but is obnoxiously great for EDM, rock metal and hiphop just like the TSMR-X.

The crazy thing about the FEAT is that you can’t tell just how brawny the bass end is until a tune clearly has some subwoofer engagement. Meaning it has some very clear clean mids. Which I don’t think can work with just how much bass these things have from something like a single dynamic using a single sound channel for example. Folks that like clean sound tunings should love these things but then when the subs are engaged. Get ready to rumble!

This bass ability makes for an ideal IEM for out and about not to mention will be ideal for gaming and media watching due to its technical level and bass emphasis.

Bass here is tuned a bit differently than the bass end of the TSMR-X, while both are using carbon based dynamics and both are using that push pull configuration. These sound a bit more closed in by nature and dbs per db actually sounds more impactful, has just a bit more physical nature to its impact and rumble. Don’t know if it is the venting driver that was used on the TSMR-X but these are not quite as well controlled, I don’t feel the bass end here is sloppy on the other hand.

Bass can and does get burly, definitely has more sub bass vs mid bass If I put the bass quality at a 8 out of 10 for the TSMR-X I would put the bass end at a respectable 7 out of 10 for the FEAT. Sub bass on the FEAT is where these become straight smile inducing experience. Its addictive rumble is shocking at times and has a slow decay for its sub bass rumble like a real subwoofer. As brawny as the bass can be, it is once again the control aspect for its bass which is clearly there. The bass for the FEAT has actually grown on me and you know you're dealing with a colored sounding IEM when other IEMs I go back to sound like they have weak bass in comparison.

I think if these came out before the TSMR-X I would have been head over heels over this one but as things stand, the TSMR-X has been making waves and I have a feeling it will be Tansio Mirais most popular IEM to date for a good reason. I do believe the TSMR-FEAT is a younger brother to the TSMR-X and as such there are a lot of striking resemblances to its sound formula.

So how does the TSMR-FEAT slot in the scheme of things? In my guesstimate it gives a good solid 85% sound performance of the TSMR-X and it is sold at a bit over 60% of the price of the Tansio Mirai-X. Which makes them a good value proposition for IEMs. But then it has its own sound going for it.

Its less aggressive treble balancing actually makes for easier listening while maintaining that clean mid-range, Tansio is known for. The mids are positioned very similarly as the TSMR-X and this one is not for folks that like a more forward warmer mids profile. It's more neutral in its mids presence but still has that dimensional quality to the mids that becomes addictive to listen to.
If any of you guys reading this was curious about what the fuss was about on the TSMR-X. This is a very good option to get yourself a legit audiophile bass infused IEM. If your curious about my take on the TSMR-X here is my review of them.

Several negatives on this one, for folks that are curious about them but feel the TSMR-X is a bit too spendy for you. The TSMR-FEAT will make you curious about the TSMR-X. On the other hand it is most definitely competent enough of a sound on its own with its own flavor.

It has two contrasting tonal qualities, clean and dark at the same time. I feel cohesion has improved greatly since burning them in but it would be difficult to have this much dynamic bass emphasis for BAs to jive with tonally. If you have a 2.1 or 5.1 system at home you might get a good idea of how the sound projects in the ears for this one. Short nozzles, yes these have short nozzles. I had to revert to using a double flange which brings forward the mids and trebles a bit forward for better balancing. Otherwise I am waiting to find out what these will be sold for. In the end these are true audiophile bass IEMs. You want your detail and imaging a clean sound signature with a low visceral rumble? That is exactly what the TSMR-FEAT are all about.

crazy bass thick rumble yet we have the felt round punch too....meaty low end that dont eat the mids....they feed it. vocal are quite superb too...
extremely addictive

Great review! I am really happy with the X, otherwise I’d be really tempted…
The appeal of these I can understand. At the price point there will not be too many that will top these for bass engagement. These are what I hoped the old GR07s should have been. I think if I didn't have the TSMR-X already these would be a no brainer but they have their own appeal.

I quote
