Lovable Incoherence
Pros: Spectacular tonic-muscular, detailed, engaging, clear presentation.
Beautiful, powerful, dry bass. I
Very pleasing unique musicality in spite of a modest timbre mismatch.
Very good technicalities
Cons: SpSomewhat too slim mids and vocals.
Imperfect horizontal timbre coherence between DD and BAs.
I’ve been loaned a privately owned iBasso IT07 sample and here’s my experience with that, reported following my usual review format.

IT07 is iBasso’s flagship featuring 1 DD + 6 BA, costs a pretty penny – $899,00 – and was released some 3 years after IT04 (1 DD+3 BA), which I also will publish a review for in the next days.

I did not get the entire package so I couldn’t properly assess some secondary elements like the black and gold nozzles or the stock tips, but I reckon what I got is more than enough to form a solidly educated opinion on what we are talking about. Here we go.

Test setup

Sources: Apogee Groove + Burson FUN + IEMatch / Apogee Groove + iBasso T3 / Sony NW-A55 mrWalkman – Sedna Earfit Light Short tips – Stock High Purity Silver Litz cable – lossless 16-24/44.1-192 FLAC tracks.

Signature analysis

Adopting silver nozzles IT07 has a frantastic dry-natural timbre, with some thin treble nuances on top depending on accessory (cable, tips) selection. The presentation is a W, with a note body that I’d call “muscularly tonic” both on bass and trebles, while mids and vocals stay by a whiff on the “slim” side. The DD presiding to the bass section is masterfully tuned for speed and punchiness, however the Knowles BAs quite often overpace it, resulting in some degree of timbre incoherence. Dismissing critical listening and just following the music flow, however, the comprehensive result is nothing short of gorgeous, especially when highly rhytmical genres eg funky, jazzrock, fusion are involved.

Sub-Bass Elevated in quantity yet very dry, rumble is present at all times when percussions are involved and it reaches deeeeep down.

Mid Bass Mid-bass is strong, fast, intense such as to fill the place, yet perfectly “dry”, missing any form of haloing let alone bloat or veiling power. As mentioned above the bass driver comes accross “not perfectly homogeneized” with the 6 BAs taking care of the rest of the spectrum in terms of note body, yet I would say manly due to the dryness of the bass tuning such “mismatch” is far from being fastidious like it happens in so many other cases, it rather comes accross as an acoustic band featuring an uncommon instrument mix, which may make you raise an eyebrow at first glance, but catches your appreciation right after the second tune, and you never want the show to end.

Mids IT07 mids sound quite natural but not 100% organic. They are greatly articulated, nuanced and all, but they do lack that last 5% of “fat” to let my brain “recognise” guitars, or vocals, as “the real thing”. In short, they are a whiff too slim, although I would not call them “lean”.

Male Vocals Males are well presented, never covered by the bass, never congested, articulated and nuanced. Just a bit too dry to sound fully real.

Female Vocals Similarly to males, female voices too are restituted with great technicality with just a veil of artificial varnish on top, due to the lack of some “skin grease” so to call it, some butter is missing. IT07 are many great things, just not the best vocal driver you can buy.

Highs Trebles are very vivid, sparkly, clear and detailed. Presence is airy, and although brilliance is definitely tamed, IT07 at all times offers the impression of delivering fully extended trebles. Depending on accessories selection you may make them a bit hotter, or a tad more “combed”. After quite a long selection I “think” I prefer a more energetic variation like the one offered by widebore silicon tips, yielding in a perfect balance between subtlety and not body up there – for my taste of course.


IT07 have a very wide stage, with good height and depth.

Imaging Imaging is spectacular thanks to the general presentation clarity and the bass being so sharp while at the same time not even remotely shy

Details The level of detail is very significant, both in the bass and (even more) on the high mids and trebles, without scanting into the fatiguing extra-thin excess.

Instrument separation Separation and layering are very well executed, possibly not the absolute best I ever heard in this price range but – at the very least – in line with the expectation I would have from a product of this class

Driveability IT07 are not a boulder to move in terms of amping “power”, but that’s not the correct point to make here. Their capacity to draw on space, and resolve details and layers strongly calls for the adoption of a “non-basic” DAC + AMP at the very minimum.


Housings are bulky. Lightweight enough, they are shaped in a CIEM-like style similarly to IT04.

Fit After the usual long rotation session I identified two tip alternatives offering different fits and quite different presentation results: 1) Foams, and a quite deep insertion to get slightly softer edges on the bass, and some of the extra-thin treble details combed down, and 2) Sedna Earfit Light Short, leading to a “hotter” delivery accross the board: bass is razor sharp, mids are brought a 10% forward, and trebles are left unbridled but somehow still kept substantially inoffensive.

Comfort As mentioned above IT07 housings are CIEM-like shaped but nozzles are quite long and this does not help them stay perfectly firm into my outer ear. Too bad. Foam tips do help a bit on this too. Short-stemmed silicons are, alternatively, key.

Isolation Housing shapes, their long nozzles and the adoption of foams make passive isolation at least decent.

Cable IT07 come with iBasso’s High Purity Silver Litz cable, offering splendid construction quality, dual connectivity (2.5mm native + 3.5mm daisy chain adapter), and crystalline sound, pairing with IT07’s BA drivers to deliver that extra tad of brilliance and subtle detail retrieval. Reeeeally good. Of course a more laid back alternative may be wanted in some cases, or by some in all cases – it’s all a matter of preferences as always. To get there I tried to pair a CEMA EA RX (6N OCC + SPOCC) as an “intermediate” choice, and guess what… a final C112 (a.k.a. E4000 stock cable) being one the absolute best OFC cables I ever tested. IT07 resolving power makes justing of the subtle, but absolutely hearable differences amongst the 3 cables resulting in 3 different variations, all 3 so good that’s really difficult to pick one as absolute best.

Some quick comparisons worth mentioning

iBasso IT04
The key here is not being mislead by model naming: IT07 are not the direct upgrade to IT04, their intendend tuning and presentation being different. IT07 is indeed “technically superior” to IT04 on a few aspects, vis-a-vis an 80% higher price of course, but the tonal profiles are very obviously not the same and make up for two very different musical outputs.

IT04 is a warm-balanced open-V, instead of a dry-neutral W. IT04 has slower, meatier and more flowery bass, vs more elevated, more extended and way faster and punchier bass on IT07. Mids on IT04 are tonally more organic then on IT07, where they are better detailed though. Most of all, IT04’s trebles are combed, relaxed, very carefully finetuned to always come accross perfectly coherent with the DD in charge of the bass part, while oppositely IT07 features livelier, sparklier, way more detailed and airier trebles, indeed presenting a timbral incoherence with their DD for the purists though.

IKKO OH10 ($199,00)
Of course the comparison is totally unfair on the technical proficiency level – and better be, considering a 4.5X price gap! – but I’m mentioning OH10 precisely due to their almost identical tuning compared to IT07.

As a matter of fact, OH10 can easily be called “less expensive IT07” by anyone looking for a powerful, engaging, and most of all unforgivingly dry, ubleeding bass, paired with very lively and well tuned highmids and trebles. Mids are dry and slim on OH10 as on IT07, but they go as far as being “lean” on OH10 in comparison. OH10 are equipped with a single not-TOTL Knowles BA so we can’t reasonably expect the same IT07 proficiency in rendering anything above 1000hz, nor on detail retrieval – it being understood however that, conversely speaking, OH10 does wonders on those registers for the exact same reason! IT07 technicalities are also obviously more refined and downright “better” than OH10, while OH10 comes out a bit better in terms of timbre coherence between their DD and their (sole) BA compared to IT07’s 1+6 scenario.

DUNU ZEN ($699,00)
IT07 extract more highmids and treble thin details; cymbals are crystally adamant when they need to be, unlike on ZEN where they are somewhat “polished”, “matte” in a sense. Midbass are equivalently articulated on either, while perceivably oomphier on IT07, which is not necessarily better depending on taste and track. On ZEN mids are obviously airier, more bodied and totally organic. Piano notes offer the impression of spreading in an infinite space on ZEN. On IT07 mids are defintely slimmer, bringing them to the edge of unrealism, and sort of confined inside a room – a big room at that, but I do perceive the space as “finite”, whereas it is almost not on ZEN. Finally, ZEN offers a totally coherent timbre accross the entire spectrum, unlike IT07 as detailed above. Such very last point is what keeps me personally from granting IT07 360° “Excellent” status, but that’s a millimetric flaw when cast against the full product panorama.


IT07 impressed me a lot. I guess it comes from me liking OH10 tuning so much that my ear and brain really rejoyced in hearing that presentation’s direct evolution and sustantial refinement on the IT07.

IT07 offer a literally spectacular, energetic and at the same time very refined musical experience. While one may count their slight internal timbral mismatch as a coloration, which it is, the practical result is nothing short of lovable, and I’m up to strongly recommending it as a high-end driver ideal for a wide extension of different genres.

As mentioned above the sample I auditioned was loaned to me by a private owner, who paid for it off his own pocket.

iBasso I07: Comprehensive Heaven
Pros: Sound, ergonomics, design, workmanship, kit.
Cons: No, although the price is still high.
O heaven, let me be beautiful,
To the earth that comes down from above,
And radiant and impassive,
And all-encompassing as thou art.

D. Merezhkovsky

Hi Friends!

It is so difficult for me to translate these poetic lines, we lose rhyme, but I hope that I was able to convey the meaning of the verse to you.
I do not know how the poet of the Silver Age Merezhkovsky could describe our today's guest so accurately, but the fact remains - the lines that open our review ideally characterize both the appearance and musical style of the new flagship headphones from iBasso. Perhaps the whole thing is in the noosphere - the thinking shell around the Earth, but I will not say this.

Yes, I finally got the IEM IT07 model, with which I was so looking forward to meeting! These wonderful in-ear monitors are built in a hybrid scheme and each have seven drivers on board. They also have the ability to tune the sound using acoustic filters.

It's no secret that every new iBasso development is a remarkable event for me personally, because getting to know any creation of this company is always an interesting and exciting activity. Needless to say, this time too, my expectations were fully justified? These IEMs not only allow you to deeply enjoy the music you listen to, but also bring romance and poetry to life!

And before I start writing poetry instead of writing a review, let's immediately get down to the heavenly IT07.


Text: Alexey Kashirskey (aka Hans Barbarossa)

Type: in-ear / hybrid
Drivers (7): 1 (10mm High Magnetic Flux Dynamic Driver) + (6 Knowles BA Drivers)
Impedance: 16Ohm.
Frequency range: 5Hz-40kHz.
Sensitivity: 108dB/mW.
Noise isolation: -30dB.
2.5mm-3.5mm connector included in the package.

Appearance, kit and ergonomics

The "Seven's" arrived in an elegant black leather-wrapped box with the "iBasso Audio" logo embossed on the lid, which is in a cardboard box.


We open the lid of the magic box and extract all the contents from it: a metal case-washer with an IT07 IEM inside, a removable cable with an adapter (2.5 mm / 3.5 mm), 12 pairs (one more is already installed on the headphones) silicone tips , two pairs of foam tips, a metal plate with three pairs of acoustic filters (black, silver, gold) and mandatory warranty documents. Wow, how much is there! Without hesitation, we put five plus for the set.




We take out IT07 ourselves and start admiring it. The azure mother-of-pearl polymer cases are handcrafted, polished to perfection and look extraordinarily beautiful. You hold in the palm of your hand these two pieces of the spring sky with floating whitish clouds and you forget where you are and why you even got these IEMs. How romantic and poetic IT07 looks!



The iBasso slogan "InTune" shimmers on the faceplate. On the inside of the shell, there is a metal sound tube with a wind-up acoustic filter, which also protects the IEM from moisture and sulfur. Slightly below there are two compensation holes, on top - a gold-plated connector for connecting the MMCX cable.




IT07 is quite lightweight and extremely ergonomic, you can wear them for as long as you like without discomfort. It is expected to be worn behind the ear.
Inside each IEM fit one (DD) 10mm Tesla coil driver, six (BA knowles) drivers, and a 4-way crossover.
Sound insulation is above average, and if you choose the right tips, you can stay tete-a-tete with your favorite music and not be distracted by the hustle and bustle of the outside world.




The 4-core braided cable is made of high quality silver litz wire. It is silver-colored, braided, very elastic, with MMCX connectors, a 2.5 mm TRRS balanced jack and an adapter to 3.5 mm TRS, all in the same style.



Well, a few words about filters:
Silver - neutral with a slight high-frequency accent
Black - emphasizes the lower and midrange
Gold - for those who like to highlight low frequencies


And since we have already started talking about the sound features of the IT07, it's time to move on to the next section of the review.

Sound impressions

Listening (audio testing) was conducted on: MyST DAC 1866OCU V.2, iFi iDSD Diablo, Lotoo paw Gold, iBasso 220 MAX, iBasso DX300, QLS QA-361 & iFi HIP DAC.
Most of the time testing was done with silver (gray) filters.

My regular readers, probably, have already learned the next passage by heart, but in this case, it is better to no overlook it: I recommend that you take a responsible approach to the process of selecting tips, since they make a noticeable contribution to the creation of a sound picture.
With all devices, the "seven's" played excellently, their voice slightly changed depending on the sound source.


I would describe the sound of iBasso IT07 as tending to neutral, with a good transfer of the emotional component, high resolution, a well-boosted section in the low-frequency register, smooth, detailed and extremely musical, melodious mids and slightly sparkling high-frequency range. All material is presented reliably, thoroughly and utterly melodic.



IT07s deliver a balanced, dense and euphonious sound, with a harmonious display of micro and macro contrast.
The musical canvas is drawn widely, in detail, with good separation of instruments, a clear transfer of textures, timbres and a scrupulous display of small nuances of the composition.
It is a dynamic and proportionate manner, where the drawn audio images, exquisitely intertwining, but not interfering with each other, line up in a sophisticated soundscape. iBasso IT07 has excellent stereo panorama and good resolution, presenting compositions legibly, smoothly, broadly and musically.



The beat is precise, deep, going to the very bottom, the bass parts are worked out richly, richly, bitingly and distinctly. The dynamic driver is well tuned and therefore capable of a lot. He easily cools our ears with crisp pops and solid, tight "pump". The bass is textured, rounded and agile, filling the middle with warmth and lively bodily substance. There is not even a hint of hum and bubbling, but there is a clear working out of the lower range, which most tactfully contributes to the overall tonality.
Accuracy and intelligibility, relief and comfort - working out the midbass takes not so much quantity as quality and reliability, demonstrating an excellent transfer of textures and energy. And if you wish, you can add or subtract Lows, for this we have acoustic filters.

The mids are smooth, detailed, comfortable and melodic. Here, no detail escapes the listener. Musical images are drawn large, convex and tangible. The middle is extremely expressive and is not spoiled by sharp annoying peaks and any distortions. IT07 gorgeously convey the emotional component of the composition. They easily captivate the listener with their melodic manner and do not let go until the very end of listening to the composition.
Vocal parts are conveyed purely and emotionally, and strings sound rich and realistic. The timbres and reverberations are very good: natural, musical, deep and bewitching. I would call this presentation of sound solid, melodic, extremely smooth and detailed at the same time.

High frequencies are reproduced clearly and harmoniously. There is a slight accent here, around 7-8 kHz, but it is presented quite correctly and does not in any way refer to annoying factors. Highs add a bit of breadth, expression and fresh air to the overall sound. They do not try to amaze the listener with refined manners and refined after-sounds, but at the same time they are conveyed quite cleanly and beautifully, intelligibly and competently, legibly, without excessive harshness and obvious simplification. This is an expanded, rather spacious and beautiful presentation.


Well, do not forget that we can always tune the sound to our taste using acoustic filters.


In terms of genre preferences, iBasso IT07 are not whimsical at all: they play very interestingly both classical music, instrumental, jazz, electronics, rock, and brutal genres.


In my opinion, the engineers of the iBasso company once again coped with their task brilliantly, making the IT07 a delight for both ears and eyes. Impressive sound, housed in an elegant body, is the key to the success that this model no doubt awaits.
These IEMs turned out to be interesting in everything: chic design, ergonomics, good kit and, most importantly, good sound with its captivating charm and graceful flavor. Such an audio signature, in my opinion, should be of interest to an extremely wide range of listeners.

IT07 is clearly the flagship model of IEM without discounts or reservations. These are the IEMs that will adorn any audiophile collection and delight even the most ambitious high-quality sound lovers.
The MSRP for the seven's from iBasso is $899. Considering all the above listed advantages of the model, I consider this cost quite acceptable and highly recommend IT07 for purchase.

Thank you so much for this in depth review on the back of which I purchased them and I am so glad I did. Great IEM's.
I wonder how is it compare with dunu sa6??
@V1nc3nt I haven't heard the SA6, but I would say that they are at least different in the lower end (which will affect the overall sound) because it is an all BA set, where the IT-07 has a DD for the lower end.


Headphoneus Supremus
Some things change, some things stay the same.
Pros: low end presence, timbre, musicality, lush and vivid sound, female vocals, classical strings, value
Cons: occasionally male vocals lack thickness and body

Hello, and welcome one and all!

Are we all sitting comfortably? Then I shall begin.

Once upon a time, a well-known and respected manufacturer of DAP’s suddenly announced that they would be releasing a new IEM (the excellent IT03)...

I actually considered writing the whole review in story format, but I’m in a hurry, so perhaps another time :sweat_smile:

In fact, I’m surely going to flex my creative writing muscles and do exactly that sometime soon. Now that the idea has popped into my head, I can’t forget it, and it sounds (to me at least) like a lot of fun :)

Meanwhile, back to the iBasso releasing their first IEM part!
Well, that was back in 2018, if I recall correctly.
Fast forward a couple of years, and I think it would be fair to say that iBasso have similarly established themselves as a name of note in the world of IEM manufacturers too now.

Today, I’ll be reviewing their latest offering, the IT07.
This is a new addition to their ‘In Tune’ line-up and is another hybrid IEM.

All details can be found on iBasso’s website (link below – despite the correct name, it didn’t seem to go to a particular product page, but I don’t know if that’s a temporary glitch or not), and the IEM can be purchased there and delivered to locations around the globe. It can also be purchased from various other dealers globally of course too.

The IT07 features a dynamic driver, along with 6 x Knowles balanced armatures and ergonomically designed shells.
See the link above for all the details :)
The RRP at time of writing was $899, placing it – financially speaking - at what I suppose these days would be close to the upper limit of mid-fi level.

My sincere thanks to Paul and the team at iBasso, for providing me with a review unit to keep in exchange for an honest review.

Well, now it’s time to indulge in some vicarious thrills and see what the IT07 actually look like!

The cable, plus 2.5mm to 3.5mm adaptor:
The same cable, deconstructed!

Unboxing, packaging and accessories:

The packaging and accessories are nicely done, and the nicest yet from iBasso with regards to their IEMs.
There’s a metal case with a soft lining, comparable to those released with TOTL products.

The cable here is a very nice pure silver Litz cable. It feels fine in daily use and I haven’t noticed any particular issues with it. It’s terminated in 2.5mm balanced.

At this price point I think I would have liked to have been given a choice of termination options (in which case I would have gone for 4.4mm), but I’m fairly happy to let that go, given that there’s currently a pandemic causing havoc all over the world, and also that at least a 2.5mm cable can be plugged into an adaptor to easily make it into 3.5mm or 4.4mm.
Hence they are making it available to the widest range of consumers.
There are IEMs costing 2-3 times the price that come with 2.5mm or even (shudder) 3.5mm SE, so it’s not so bad overall :)

The Fit:

The shells are smooth and very comfortable in use. Since their first IEM, the IT03, iBasso have adopted a kind of semi-custom shape to their IEMs, featuring – in one form or another – some kind of nodule which sticks out a bit from the shell.

They’ve revised the design a few times, but with the IT07, I think they’ve perfected it this time. Well, for my ears at least! Of course that’s a personal thing and others may find a better or worse fit.

But since I can only speak for myself, I’d say the fit, with New Bee foam tips, is superb for me. I compress the foam tips, then insert the IEMs one at a time, pulling on the top of my ear as I do so to open up the ear canals a bit more.

I purposefully insert the IEMs at about a negative 30 degree angle from upright, and then twist them into position. Doing so, there’s a delightfully satisfactory feeling each time, as the little nodule which sticks out from the body locks into place in some part of my ear (concha?) for which I am not sure of the name :)

It’s probably similar to the feeling a Rolls-Royce owner will get upon closing the perfectly-engineered door before heading to their private jet.
Alas, such a luxuriant feeling is deprived to Layman1, having only a couple of Lambo’s myself*, but at least I can console myself with the wondrous ergonomics of my IT07 :)

*Well, I’ve seen a couple of Lamborghini’s once. Does that count? :wink:

All in all, they are extremely comfortable, and I have been able to wear them for extended listening sessions with no discomfort or fatigue.

The Sound:

I listened using the Sony WM1Z DAP, with MrWalkman’s custom FW (DMP-WM1 Mk I), and the DX220MAX, combined with a variety of tracks in lossless or hi-res lossless format.

I used New Bee foam tips, which are my go-to tips and pretty much consistent across my reviews, although I may try other ones alongside as needed.
I’ll begin with the summary of my findings, then some comparisons, followed by a brief conclusion.

As a note before I begin, the IT07 distinguishes itself by including 3 tuning filters in the box (Black, Gold and Silver), that screw onto the ends of the nozzles.

Like many such filters, they seem to be primarily about altering the amount of bass in the sound signature.

The black filter seems to bring out the low end a bit more prominently with slightly recessed mids, whereas the gold one diminishes both mids and treble somewhat (or enhances the bass at the cost of them) for a more L-shaped signature (think EE Legend X, or iBasso’s own IT01).

Finally the silver filter is effectively our ‘neutral setting’ not in the sense that it changes the IT07 into a neutral-reference sound signature, but rather that it lets the pure original sound of the IT07 come through without any additional colouration one way or the other.

I actually like this filter the best and stuck with it.

Low end:
This is a real strength of the IT07. I hear the sub-bass to extend deep, and unlike some other older iBasso IEMs, there’s an above-neutral amount of mid-bass presence here too.
The effect is a low end that’s rich, powerful and brings the emotion into the music.

I hear it as having quite a good balance of accuracy and decay; the timbre is realistic and as an example, when I listen to things like ‘Midnight Train to Georgia’ by Gladys Knight and the Pips, or Paul Young’s cover of ‘Everytime you go away’, the IT07 absolutely nails that quality of infusing head-bobbing musicality into the music via the basslines, and with the drums and percussion too in other songs. On a song like “Please don’t fall for me” by Norwegian pop singer Marit Larsen where the drums are mastered quite powerfully in the mix, the kick drum that comes in at 0m28s has a really rewardingly solid thump and impact.

Some warmth and richness comes through from that mid-bass. I hear the mids to be perhaps slightly forward – if so, it’s more the lower mids than the upper mids – full bodied, natural and with quite big note size. There’s a lushness and a vivid quality to the sound here, with strings sounding particularly fine; on ‘Little Sister Leaving Town’ by Tanita Tikaram, there’s real timbre in the ‘bite’ of the cello bow against the strings, and a rich sweetness in the violins.

On ‘Future Days’ by Pearl Jam (a beautiful acoustic number) there’s such definition with the opening instruments, although I found the vocals to sound a little lacking in body and richness for some reason. IT07 manages to bring great clarity, something which might have been hampered by the note size and lushness on an IEM without this level of technical performance. All instruments seem to have clearly defined edges, but enough decay and richness to bring out the best in their timbre.

Having said that, despite the lushness and whatnot, I hear male vocals to be presented accurately and fairly centrally in the soundstage, but on some tracks I feel they could use just a touch more thickness and body; I don’t feel this with instruments, so perhaps it’s related to a particular frequency having been elevated or diminished in the tuning of the IT07? Having said that, listening to “One minute you’re here” by Bruce Springsteen, all that body and richness is there in his voice (also, the chime sounds that come in from 1m47s onwards are gorgeously presented!).

So it does vary from artist to artist, and even (in the case of Gregory Porter) from song to song.
Oh, and his song “Don’t be a fool” could have been made for the IT07; sheer perfection here, with every instrument infused with richness and a gorgeously smooth musicality :)

I don’t hear any such issues with female vocals – listening to some Chinese pop songs, the vocals sound fantastic – among the best presentations I’ve heard on any IEM; a real strength here - but the same goes for female vocals in pop, Motown and opera too. Even on Hong Kong opera singer Alison Lau’s rendition of Handel’s ‘Lascia la spina’, the vocals never became too piercing due to the smoothness and richness of the IT07’s tone, whereas they do on a great many IEMs for me.

I hear the highs to be fairly extended. There’s some air infused into the sound signature, just enough to bring balance and space amidst that lushness. I wouldn’t describe them as bright or sparkly, although those qualities will vary with ear tip selection.

Technical performance:
Detail retrieval is very good; not at the superlative levels of the UM MEST or the EE Odin, but then few IEMs are! Still very good though, and fairly organically done. There’s not that sense of almost clinical dissection you can get with a super-detailed IEM; the details just naturally come across to you as an integral part of the song, rather than seeming like a spotlight just picked them out.

I hear the timbre as being natural and realistic, infused with richness and body for the most part. Layering is done pretty well, albeit without a vast amount of air-infused ‘real estate’ to really bring a great deal of space, but certainly there’s never been a feeling of congestion.


IT07 vs IT04:

Regarding soundstage, it’s not an easy comparison. I’d say they’re probably pretty similar, but the sound signature of the IT04 makes the fairly holographic soundstage more immediately apparent, whereas with the IT07 it’s there too but the big notes, vivid sound and contrast fill up the space more and the size of the soundstage becomes noticeable here and there as you notice sounds occurring out at the edge of the sphere.

The low end is a real stand-out of the IT07, and one of the ways in which it differs significantly from its predecessor the IT04. I love that IEM, but the IT04 is a kind of a classic of the old iBasso house sound, with a fairly neutral-reference sound signature, with a touch of organic warmth and shimmer and a fairly neutrally tuned mid-bass, but a deep sub-bass extension that can kick in when appropriate.

The IT07 has much more ‘contrast’ than the IT04 for me; it’s more vivid, saturated and rich; not to excess, but it can’t help standing out in this regard next to the more classical sound stylings of the IT04. I think the IT04 does delicacy and shimmer with more finesse, but the IT07 is certainly capable of a lighter touch when the track demands.

IT07, CA Solaris and UM MEST (original):

Finally, rather than a set of direct A/B comparisons here, I’m going to talk about two IEMs from my collection that I found the IT07 to share certain qualities with, as in some ways I feel this would actually be more helpful.

Of all the IEMs I own or have heard, the IT07 most reminds me of a kind of hybrid between the original Unique Melody MEST and the CA Solaris 2020; it has a fairly deeply extended sub-bass which reminds me of the MEST, along with a rather W-shaped signature, but also – at certain times – something of the more intimate, slightly dark and mid-bass rich sound of the Solaris 2020.

It doesn’t quite have the huge, open, airy holographic feel of the MEST – although I’d say it gets about 70% of the way there. That’s not in any way a criticism of the IT07 though; it’s simply a somewhat different sound signature, the same thing I’d say about the Solaris 2020.
What it does share too with the MEST is a very vivid feel to the presentation, with a lot of energy, but not in a fatiguing or sharp way.

I think the Solaris 2020 is an excellent IEM and the IT07 also takes some qualities from that IEM that I really appreciate; it’s capable of a more intimate sound, despite a fairly expansive soundstage, and comes across as a bit darker to me than the MEST, more like the Solaris in this regard. However, I do hear a bit more separation and soundstage size with the IT07 than the Solaris and a more immediately noticeable presentation of detail.

I think Solaris 2020 has the edge in timbre, though it’s a close thing and both IEMs have a fairly rich tone, with IT07 more rich and vivid, vs Solaris 2020 being more rich and dark.


With their recent DX300 DAP release and the IT07 IEM here, I feel iBasso made a small, but noticeable shift away from their classic ‘house sound’.

There’s more organic warmth and musicality on offer with both. I’ve already reviewed the DX300 previously, so I’ll naturally keep my comments here focused on the IT07.

I hear it as approximating a W-shaped presentation, with a meaty and powerful low end, lush and rich mids and a treble lifted and extended just enough to balance out the lows and mids with a touch of air and shimmer.

Technical performance is excellent, although less clinically analytical and more musically organic.

I found male vocals on the whole to be good, but on occasional songs, felt there could have been a bit more thickness and body to them. However, this didn’t happen consistently, so it’s probably a case of listening for yourself with your favourite male vocalists and seeing if it matches what you like.

Conversely, female vocals were – for me – outstandingly well-presented across the board.
From opera to Motown, Chinese pop to Bollywood, the female vocals were infused with a rich tone and body, and never became too shrill, even on tracks that usually trigger me with most IEMs.

There’s a lush and vivid quality to the sound signature that’s high in musicality, and the timbre is natural, rich and accurate.

This is an IEM that will have you tapping your toes/bobbing your head/playing air guitar or whatever form of physical expression you employ when enjoying your music :)

It stands up well against IEMs in the TOTL category, and all at a price of $899.
Once again, I feel iBasso have produced a contender for ‘value product of the year’.

The sound signature might be moving in some new directions, but their commitment to value and quality remain wonderfully consistent.

It’s been a pleasure for me to review this IEM, and I hope you’ve enjoyed reading about it :)
@samandhi Many thanks! Really appreciate you taking the time to write that and I'm glad you love the IT07 as much as I do :D
Again another great review, thank you. I am so glad to have found this site, my wallet isn't lol. Added these to the slowly expanding collection.
@TheHelper1964 Many thanks! I reviewed the UM MEST and MEST Mk II as well, but you probably don't want to read those, for the sake of your wallet and all :stuck_out_tongue_winking_eye:
