DITA Audio Project M

General Information

DITA Audio Presents: Project M

In the spirit of continuous development and evolution, DITA introduces its first resin-based, hybrid earphone, the Project M.

The M’s physical appearance is a departure from previous DITA designs, taking on an even more ergonomic form factor that is at once familiar and yet uniquely DITA.

The Project M consists of DITA’s all-new PM1+ Dynamic Driver and a balanced armature driver.

As with all of DITA’s pieces, the Project M aims to be something that can be kept and enjoyed for a long time: It will be backed by a self-mandated 10 year parts or replacement availability that speaks to DITA’s commitment to stability, long term viability and re-sale value.

I had a pleasure of listening to Dita Audio Project M IEM (and Dita Navigator DAC) courtesy of Audio Geek EU Tour. Big shout out to you guys, you’re an awesome bunch.

On the first listen straight away I thought it sounded... different but I couldn’t really put my ears on it :) Perhaps, I was thinking, because I just switched from BQEYZ IEM (WIND) with the bone conductor technology. At first I wasn’t too impressed and was trying different eartips and different dacs/amps configurations. The more I listened however the more my ears got attuned to them and I started really liking what I was hearing and so one night I stayed until 2:30am (we’re talking 4.5 hrs of continuous listening here - which in itself speaks volumes) going through a lot of my favorite albums and really enjoyed the experience. I would describe the overall tuning as very clear and balanced; nothing stands out. It is however somehow restrained in upper mids and treble and the low frequencies lack some rumble.

I have tried the following configurations throughout the 2 weeks I had it.

M with Meridian Explorer 2:

Midrange was brought slightly to the front, soundstage was nice and wide and imaging pretty good but I could hear occasional sibilance on some tracks. Treble notes were slightly rounded and rather soft but in general everything seemed to blend together really nicely in the mix providing very enjoyable experience. Bass was deep and powerful and latest Peter Gabriel album (I_O) sounded great on it (both Bright and Dark mixes).

M with Bottlehead Creek:

Everything sounded more cohesive; background instruments were more prominent, vocals were clearer and music had more body to it with more realistic timbre to the instruments. Overall presentation was laidback. Listening to Close to the Edge by Yes was an immersive experience and it did pretty good job at presenting all this different layers of instrumentation in the tracks.

M with Navigator (balanced output):

In short: best dynamics and more texture. Bass was more prominent, tighter and emphasized; Treble slightly more extended; Soundstage was wider and it provided amazing imaging (it really shined on Waking the Witch by Kate Bush - that OH WOW effect :)); instruments separation was quite impressive and there was more weight to the notes. Midrange sounded particularly sweet and warm.

I have tried some jazz records in this configuration, for example Gary Burton’s Like Minds. Vibraphone had a nice timbre, double bass was very well articulated but I would like to hear more rumble there; treble lacked a bit of sparkle and extension. Overall presentation was accurate and I was able to follow each note even in the fastest passages of music.

As the final test I tried it with my digital piano and unfortunately the sound was a bit grainy, and not smooth or clean, which was a big surprise.

To summarize, I really enjoyed Project M and for a while was even thinking that I could settle for this kind of tuning but eventually concluded that it was a little bit too tamed and lacked in the engaging and captivating factors which makes listening to our favorite music just that extra special. Surprisingly I realized that I actually prefer a slightly more prominent treble and more technical performers than I thought before, so that in itself was a very rewarding experience. I absolutely loved the see-through design and the fit they provide was the best I have ever experienced in any IEMs so far.

DITA Project M - Uncanny Valley
Pros: + Beautiful design
+ Interesting and deliberate accessories
+ Surprisingly good bass response and dynamic
+ Precise instruments positioning and wide soundstage
Cons: - Uncanny tonality
- Unnatural treble boost
- Can be very sibilant
Today, we look at Project M, a mid-fi offering from the veteran manufacturer DITA from Singapore.

Forewords​

  • What I look for in an IEM is immersion. I want to feel the orchestra around my head, track individual instruments, and hear all of their textures and details. I’m not picky about tonality, as long as it does not make the orchestra, violin, cellos, and pianos sound wrong.
  • I rate IEMs within with a consistent scale from 1 (Poor) to 3 (Good) to 5 (Outstanding). An overall ranking of 3/5 or above is considered positive.
  • Ranking list and measurement database are on my IEM review blog.
  • The terminology for subjective impressions in this review is based on the Audio Wheel for reproduced sound defined in the technical report ITU-R BS.2399-0
  • This review is possible thanks to the Australian tour arranged by Minidisc and @Damz87 (Thank you!). I have no affiliation with or financial interest in Minidisc.
  • The unit retails for A$549 at the time this review was published. Unaffiliated link: Minidisc online store


General Information​

Project M is a two-driver hybrid IEM. Its driver topology comprises a 9.8mm dynamic driver (DD) named PM1+ providing a full-range response. The DD is accompanied by a balanced armature (BA) driver from Knowles which fills in the treble region.

One of the aspects that caught my attention about Project M was the story and the people behind it. I’ll let DITA tell the story themselves.



Non-sound Aspects​

Packaging and accessories The packaging of Project M is rather nice. I like how DITA turn the grid of the frequency response graph into a design element of the box itself. The inner box of Project M also feels refined and … expensive thanks to the cloth wrap DITA uses on top of the cardboard.

The show continues with the accessories, which are surprisingly thoughtful. In the box, you will find:

  • A systainer3 box from TANOS, acting as the carrying case. It’s nifty and tough.
  • A custom-made IEM cable built from the famous Cardas wires, a highly sought-after conductor for headphones and IEM cables. The cable terminates in an in-house developed interchangeable plug system that feels quite strong and reliable.
  • A full set of special edition Final Type E eartips. The unique feature of these tips is that they can glow in the dark. Sonic wise, they are very similar, if not identical, to the normal Final Audio Type E eartips.

Earpieces design Project M is one of the most beautiful IEMs I have ever seen in real-life, period. I like how the stainless steel casing of the driver is suspended at an angle in the clear resin shell and connected to the stainless steel nozzle via a semi-clear tube. I also like how DITA hides the wiring for the Knowles tweeter in the nozzles.

Project_M_13.JPG
Project_M_14.JPG


Fit, comfort and isolation Besides the nice look, I’m happy to report that Project M also feels quite comfortable in long listening session. I did not experience pressure build up, driver flex, or any other comfort problem with this IEM.

Ear tips recommendation: I recommend going one size smaller than usual with ear tips so that I can can fit these IEMs deeper into your ear canal. It’s one way to keep the treble somewhat under control. The stock Final Type E ear tips are a good choice.



Sonic Performance​

Test setup:

  • Sources: L&P W4 + Topping G5, DX300, FiiO K7
  • Cable: Stock cable
  • Ear tips: Final Audio Type E in MS size
The subjective impression is captured using the lexicon in the Sound Wheel below. I’ll clarify the terminology as I use them. If you want to see more details of the lexicon and related reference, please have a look at the technical report ITU-R BS.2399-0.

sound-wheel.png


Timbre: It is helpful to think of an IEM as a filter that sits between the incoming audio signal and your ear drums. This filter makes some parts of the signal (frequencies) louder whilst other parts quieter. This effect can be measured objectively by the squiggly lines below, called Frequency Response (FR) graphs, which measure how loud an IEM is at different frequencies from 20Hz (bass) to 20kHz (upper treble). Ideally, an IEM should change the signal as least as possible (a.k.a., “flat tuning”) to avoid disturbing the balance between fundamental frequencies of instruments and their harmonics to ensure that they sound natural and life-like. Practically, IEM engineers can tune or “voice” an IEM to deviate carefully from the flat tuning to create interesting colouring and effects on the audio content. This voicing or tonal balance of an IEM can be denoted as its sound signature. Subjectivity is how your ears and brain interpret such sound signature and decide whether it is “enjoyable”

ProjectM_graph.png


Figure shows the frequency response of Project M against the Harman in-ear target. Measurements were done with an IEC-711-compliant coupler and might only be compared with other measurements from this same coupler. Above 8kHz, the measurement likely does not match the response at the ear drum. Visit my graph database for more comparisons.

How do you describe the overall sound signature of Project M?
U-shaped IEM with very generous treble boost. The boost is pushed higher into the 8-12kHz region rather than the usual 5-6kHz, so the impact of this treble boost would be different from the usual shoutiness or “ice-pick” harshness that you usually find on “bright” IEM. The bass is boosted above neutral, but still feel rather natural. The midrange is quite flat and neutral compared to the hyped up treble. That said, the midrange of Project M also has a subtle colouring as it feels warmer and denser than a “flat” or “neutral” tuned IEM. This warmth comes from a more reserved upper midrange rather than a boosted lower-midrange.

How does Project M balance different voices and instruments in a band? (Sample tracks: ABC feat. Sophia Black by Polyphia) First thing first: holy moly the sibilance! For example around 00:43 where Sophia Black sings “how you hold the bat when you swing”, I rarely hear such strong “s” sibilance in a modern IEM in the mid-fi price bracket. Regarding tonal balance, I find that cymbals and hats are a touch more emphasised than the rest of the band. However, taken as a whole, Project M presents the band in a balanced manner.

How does Project M balance different parts of a piano? (Sample tracks: Bach’s Goldberg Variations, recorded by Lang Lang) The treble voice is noticeably more emphasised than other voices and can sound harsh when it is played louder. Surprisingly, I also hear a warmth hue cast over the midrange and bass voices.

Project_M_15.JPG


How does the midrange of Project M handle vocals? (Sample tracks: Dreamland Express by John Denver, Kiwi wa Boku ni Niteiru by See-Saw) The way Project M presents the voice of John Denver is rather strange. Taken as a whole, Project M presents his voice with a sense of warmth that is rather pleasing. However, such warmth contrast against the abrasive, metallic edge of higher notes. For example, the line “couldn’t believe it” around 00:38 feels … uncanny due the clash between midrange and treble. Higher voices like that of Chiaki Ishikawa of See-Saw fare better with Project M.

How does Project M handle sibilant recordings? (Sample tracks: Shivers by Ed Sheeran) Sibilant recordings can sound anywhere from uncomfortable to deadly with Project M. If a recording is too hot in the 5-6kHz region, it would be alright with Project M. If the sibilance falls in the 8-12kHz region, you will suffer with this IEM.

How does Project M reproduce strings and orchestra? (Sample tracks: Now We Are Free by 2CELLOS, Ciaccona from Bach’s Violin Partita No.2 in D Minor, performed by Kavakos, Synchro BOM-BA-YE by Tokyo Kosei Wind Orchestra) There is still a rather uncanny contrast between the warmth of the midrange and the treble, which makes the cellos sound a bit unnatural and “brittle”. At the same time, there is a slight lack of authority in the lower-end of cellos. The sense of uncanny carry over to the tonality of violin, which sounds strangely dry and brittle. Thus, I was not surprised to find that everything from hand claps to high brass instruments of Tokyo Kosei Wind Orchestra sound rather uncanny and unnatural.

Percussion, Bass, and perceived dynamic: In this section, my focus is the not just the bass, but rather the sense of dynamic of an IEM. Can it convey the sense of beat and rhythm? Can it reproduce transients, the fast and large jump of loudness in the music? Simply put, is this IEM toe-tapping? Creating this energy requires all parts of the frequency spectrum working together: treble energy around 4-6kHz conveys snappy attacks of stick hitting percussive instruments at the beginning of a beat, bass energy around 150Hz conveys the punchy sensation of the beat itself, whilst the subbass energy below 60Hz creates the physical rumble sensation that convey power and atmosphere. Weak treble response dulls the attacks. Weak bass makes beats hollow. Too much bass makes bassline blurry and dulls the sense of rhythm. Thus, “dynamic IEM” is a balancing art.

Project_M_16.JPG


How does Project M convey “epic” bass lines? (Sample tracks: Heart of Courage (Live) by Two Steps From Hell, A Reckoning in Blood from The Ghost of Tsushima OST) To my surprise, Project M does a bloody great job with the big war drum used by Two Steps From Hell at around 00:30. The drum have clean and precise attack with great detail. More importantly, it can convey impact. I have the same impressions with the drum line in the Ghost of Tsushima OST. Project M is toe-tapping.

How does Project M handle a drum kit and bass guitar? (Sample tracks: Playing God by Polyphia) Project M does a great job with both drum kit and bass guitar. The first drop at 00:30 immediately got my blood pumping. The bass guitar is also reproduced with great sense of detail.

In conclusion, is Project M … toe-tapping? Yes. It feels impactful and dynamic. I would prefer the bass to extend a touch deeper and for bass notes to be a touch more incisive to handle fast basslines better. However, there is not much to fault Project M on the bass and dynamic aspect.

Resolution: To me, “resolution” can be broken down into three components: (1) Sharpness, incisiveness, or “definition” of note attacks (see the figure below). (2) The separation of instruments and vocals, especially when they overlap on the soundstage. (3) The texture and details in the decay side of the notes. The first two give music clarity and make it easy to track individual elements of a mix. The last provides music details and nuances. Whilst IEMs can “force” clarity by boosting treble to unnatural level, it might still lack resolution as it cannot “peel apart” complex tracks with overlapping instruments

resolution.jpg


Can Project M handle complex, overlapping recordings? (Sample tracks: ABC feat. Sophia Black by Polyphia) Yes, but only to a certain degree. Whilst the mix does not feel too blurry or messy, the separation between instruments does falter as the mix gets more busy.

Can Project M handle recordings with congested lower frequencies? (Sample tracks: Now We Are Free performed by 2CELLOS) To my surprise, the presentation of Project M with this track is only fair. When the two main cellos, the cello section, and the doublebasses from the orchestra compete for the same frequency band, the separation between these instruments starts to lose clarity, which in turns bring the perceived resolution of the whole recording down.

How does Project M convey micro details? (Sample tracks: Ciaccona from Bach’s Violin Partita No. 2 in D Minor, performed by Kavakos) In short, yes. The boosted treble of Project M helps it squeeze out some nuances and details. Moreover, the detail of the reverberation is rather good.

On the scale from fair (Moondrop Aria) to good (Moondrop Blessing 2) to great (CFA Andromeda 2020) to outstanding (AFUL Cantor), how resolving is Project M? Good.

Stereo imaging and soundstage: Stereo imaging or “soundstage” is a psychoacoustic illusion that different recording elements appear at various locations inside and around your head. Your brain creates based on the cues in the recording, which are enhanced or diminushed by your IEMs, your DAC, and your amplifier. In rare cases, with some specific songs, some IEMs can trick you into thinking that the sound comes from the environment (a.k.a., “holographic”)

soundstage.png


How does Project M position instruments in a complex, 3D-sounding recording? (Sample tracks: Original Sound Effect Track - Memory from Gundam Seed Destiny OST album) Project M does a rather good job. Elements of the mix feel spread out with good sense of space between them. Some front-left and front-right elements feel like they pop out of the head stage to come from the room. I would say the width of the soundstage is strong whilst the illusion of depth is above average.

How does Project M convey a sense of space in spacious recordings? (Sample tracks: Shadow of Baar Dau) Given the right track, Project M can convey the sense of spaciousness quite well.

Project_M_17.JPG


How does Project M handles sound positioning in FPS games? Surprisingly good. Footsteps and gunshots feel more spreadout and out-of-head. Whilst the soundstage has more width than depth, Project M can still convey the direction and distance of sound with great precision.

On the scale from good (Blessing 2) to great (CFA Andromeda 2020) to outstanding (AFUL Cantor), how good is the stereo imaging and soundstage of Project M? Somewhere between Blessing 2 and Andromeda



Driveability​

Specs:

  • Impedance: 32ohm
  • Sensitivity: 107 dB/mW @ 1kHz
How sensitive is Project M? Does it get loud too easily or is it very difficult to drive? Project M is rather insensitive. Even with 4.4mm balanced output, I found that I needed to turn the volume of Project M around 10% higher than other average IEMs.

How does Project M sound with a portable DAC/amp or a small music player? Project M sounds quite good directly from the W4 dongle.

How does Project M “scale” with stronger amplifier? I found that the soundstage of Project M expands a bit when adding the G5 as a standalone amplifier. This suggests a certain degree of “scaling”, but not significantly so.



Conclusions​

Writing the conclusion section of a review article is always the hard part. It’s doubly so with IEMs that I have been anticipating for a such a long time, yet the end results fell flat. Whilst there are undeniable bright spots in the overall performance of Project M, I find that the uncanny tonality due to the overpowering BA tweeter overshadows most of the good properties of this IEM. Now, of course, tonality has a subjective element to it and you might find the uncanny tonality of Project M a pleasant colouring. But if you are sensitive to how your next IEM presents the tonal quality of voices and instruments, you should continue looking.

What I like about this IEM:

  • Beautiful design
  • Interesting and deliberate accessories
  • Surprisingly good bass response and dynamic
  • Precise instruments positioning and wide soundstage
What could be improved:

  • Uncanny tonality
  • Unnatural treble boost
  • Can be very sibilant
Absolute Sonic Quality Rating: 3/5 - Good

  • Timbre and tonality: 2/5 - Fair
  • Bass and dynamic: 4/5 - Great
  • Resolution: 3/5 - Good
  • Soundstage and imaging: 3.5/5 - Good
Bias Score: 2/5 - I don’t like this IEM

The BA Driver is not used as a tweeter but helps with speed in the midrange. Everything else is handled by the dynamic driver.

I like reading through your reviews as usual and I liked this one as well. I finally found a review of PM that is not done by someone from Audio Geeks. The curious thing is, everyone from Audio Geeks who has reviewed PM only has good things to say about this iem. Kinda makes you wonder, out of so many AG reviews, not a single one criticised any aspect of the sound.

It's an excellently conducted review, for sure. I'm in Audio Geek and wrote my impressions of Project M below. There's an (informal) AG chat also, and I can relay to you that many in it were very enthusiastic about PM, so the general impressions were above average positivity, for an IEM of this price. Many were disappointed that Dita weren't offering discounts at the time, as they wanted to buy personal units. I guess any criticism of the sound is only fair if it's objective, and not based upon preferences. I tried my best to remain objective in my appraisal, and viewed it through the lens of resolution, sound stage, etc. It simply sounded great to me, with impressive detail retrieval and a comfortable fit, and I can probably tolerate more treble than some. I definitely don't have as sophisticated ears as oOgenesisOo, to asses aspects of timbre, etc, but until I find something 'superior' from the thousands of IEMs in the sub €300 bracket, M is one that stands out as being noteworthy

This hobby is an escapist's dream. Escape from daily routine and distress that's causing you via something as sincere and everlasting as listening to music. I believe that the power of music is still not fully understood since it works in mysterious ways. Allow it to do its magic on you and let your worries dissolve in melody.

Having had the possibility to try so many different sets in a relatively short time I felt obliged to go ahead and express my gratitude by trying to help some lost souls out there, just as I was when I first stumbled upon this weird hobby about wired earphones – so yesteryear! … I thought. Possibilities are seemingly endless and only by getting to meet the right people did I manage to jump onboard the train heading the 'right' direction without getting off-track thousands of times along the way. Make sure to understand the helping person's preferences and you too can find your footing and hit the ground running in no time.



Quick Intermezzo About Me

I won't bore you for too long with personal trivia, however my quick & short background resume goes as follows. Currently I am 27 years old and more in awe of sheer power of music by the day. I have always been moved by music just that slight bit more than average, I'd say. My spending started with a roughly 200€ Bose bluetooth speaker back in my first grade of highschool. What an extraterrestrial thing that was in early 2010s. And it keeps on playing to this day – a true testament of quality. Also sounded fantastic back then, nowadays … yeah, not so much. Lots of BT speakers, TWS, car audio speakers, IEMs, etc., later bring me to this day when I truly consider myself an audiophile. What brings me the most joy beside listening to music is singing, so I am currently participating in a choir and challenging myself with solo vocal covers (check the links in my signature to hear my projects). Unsure where all this leads, but the journey itself is marvelous and life is nothing but a journey.

My preferences lie somewhere in the neutral camp with just an ever so slight bass boost, but I try to keep an open mind and truly appreciate any outliers that dare do it differently. Our ears vary, so do our brain and tastes. I am an advocate for respectful discourse, especially in topics that don't even have many objective undeniable truths. Audio is one of those.

My most listened genres are, in no particular order: jazz, singer/songwriter, slow-paced electronica, ambient, rock, metal, blues, trance, techno & pop.


Disclaimer: I have been lent the DITA Project M from a friend after wanting to hear it for months and months and nearly buying it a few times already. DITA was always interesting to me as a company and the huge praise the M has been getting was increasingly tougher to ignore.


How My Reviews Are Structured

I will start off by mentioning the packaging, accessories, design & comfort, then continue by placing the showcased IEM in my special trademarked graphs & graphics, give it a score on certain qualities, and describe the main sound categories to reach the final star score. Those that are seriously considering the Project M, please do not hesitate to ask for any specifics you want me to answer via private messaging.

I have listened to songs of varied genres to better convey what one can expect from the Project M. As sources I have been using my FiiO BTR7, Venture Electronics Megatron, iBasso DX180, and Venture Electronics RA2B-FE + Prime DAC (in short, called the 'VE Stack'). Certainly no lack of power and quite a different taste on all. Listening was (mostly) done at a volume ranging between 75-85dB. I am using the stock cable and Feaulle H570 tips (after quite a bit of tip-rolling).

20241007_155822~2.jpg


Here is the quick and rough description of how I understand various star ratings:

Do not even think about it :star2:
It has too many drawbacks and gets demolished by competition :star2::star2:
This item has the potential but feels a bit too bland and has multiple issues:star2::star2::star2:
Wonderful item with rare and mostly subjective drawbacks:star2::star2::star2::star2:
Eargasmic performance with all the aspects covered at an incredibly high level:star2::star2::star2::star2::star2:

Keep in mind these ratings are certainly affected by the item's price in the overall assessment too. Sometimes that will result in slightly higher score than based solely on my scoring of bass, mids, and treble, while other times it results in a slight penalty if I deem the item a tad overpriced.

In layman's terms - anything rated below 4 stars overall does not get a space in my regular rotation and is either stored and revisited some time later again just to see if my thoughts have changed, or it gets gifted.


The Warmly Welcomed Changes I Have Incorporated

Instead of going through a million songs and describing what I hear in real-time, I have started doing it differently. I'll describe individual aspects briefly in whole.

Should you have any specific questions regarding any genres/songs in particular, feel free to contact me via private messaging.

I am still catching my stride on how to describe the sound aspects in a clearer way. It is a slow but enjoyable learning curve. I am attempting to make my reviews as ballast-free as possible. The graphics were the step in the right direction, I feel. Capturing the essence of sound characteristics in a less wordy way is next on the list. We all have our own busy schedules and I understand reading a review for 15+ minutes is in (nearly) no-one's interest.


Let's Get Going!

... but before we do, a quick word.


As you might realize by now, I am all in for a well done set that dares to go a different way. Project M does just that. It's a 1+1 hybrid with a high quality full-range DD that is supported by the BA only in the highest octaves. The transparent shell allows us to see the internals and that DD sound tube looks enormous in comparison to some other sets. Now, how well does it do? We'll take a closer look with some help from my faithful graphics and describe them in more detail.

To clarify, it is the sort of set that will absolutely not work for treble-shy (quantity of mid treble is pretty serious), because it is not afraid of putting its treble foot forward and bases the whole experience around it even though I'd argue its best range is bass. I can see bassheads being like, »oh, okay, this is niiice, but can we turn it up by maybe another 5dB?«. Consequently, this set is highly dependent on genres and even more so on recording quality and brightness – choosing meticulously is the goal to happiness. Not for those who only listen to modern pop or metal. And not for those who listen loudly – the treble will simply be too much. Those of you who exclusively listen loudly or to pop and metal, run away now. What is interesting and keeps me entertained is the openness and midrange freshness of this tuning. Each note has ample body and presence. Now sure, it won't be the most weighty-feeling of notes, nonetheless they keep the listener engaged. Captivating is the main word.

... OK, back to scheduled programming


Packaging, Accessories, Design & Comfort


I will have to skip the packaging and accessories since this set was lent to me by a friend and he only added the bare necessities to ship it safely and let me experience it in its stock form.

All I can say is this cable is awesome to me and the way the termination secures is perfect. I swapped to the 4.4 immediately.

20241004_193949~3.jpg


These should fit just about everyone unless you've got small ears or dislike deep fitting IEMs. Even then, a set of one-size-smaller-than-usual tips should solve that. Their weight is also low enough not to feel too taxing on the ears.

20241004_203032~2.jpg


I'll leave the design for you to decide, but in person these are works of art. So much so that if I was richer I'd have these in my collection just to look at them. That DD and the DITA writing on it is gorgeous. That is also why I don't think their new 'candy' colourways are the right move, but I would like the design on both of those too had I not seen the OG before.

Graphics, Graphs & Scores
A bright-leaning musical set with solid low-end support and good technicalities. Sweet culmination of attributes.

BackgroundEraser_20241019_130825990.png


As mentioned a little earlier, I have worked on trying to cut down on wordiness and all excess gibberish and rather improve upon my nikbr trademarked graphics to truly be able to compare IEMs visually since that offers an easier-to-comprehend, more interactive and simply more appealing experience.

These truly cover most topics in a pretty straight-forward manner.
I have described each of these in a bit more detail in my previous reviews. If anything remains unclear, here I am at your service.

Overall scoring looks pretty good for the M. I still need to figure out how to judge sets more fairly while staying true to this sort of simplistic approach. Perhaps I'll need to turn it around – giving the set a score for bass/mids/treble and mention in positives and negatives why the score is as is.

BackgroundEraser_20241019_141531376.png


Sound Descriptions

These were meant to be very concise, but I got carried away and wrote way too much again. Excuse me, I swear I'll get better with time.

The obvious categories will be subcategorized into a few important aspects. It is impossible to just proclaim the bass as great or not, there are levels to this hobby and since you're reading this review, you've obviously fallen deeper into this rabbit hole than many.


Bass
(some songs I used: Soldier of fortune by Deep Purple, Summer by Emeli Sande, I'm in Love by Ayo, House of the Rising sun by alt-J&Tuka, Infinity by DJ Pastis&DJ Ninu&Wasi Distorsion, Kuwait by Mazde, Drum solo by Manu Katche, Hislerim by Serhat Durmus&Zerrin, Animamundi by The spy from Cairo, Let the music flow by Sound Synthesis)

Quantity vs quality: This fits my taste to perfection. It's just right. There is ample quantity to never overstep or overshadow the midrange while also countering the lively treble. Quality is incredible. My previous favourite bass was that of the AuR Audio Aure. Project M polishes it further. The sense of ease and flow is second to none.

Rumble: While not ear(th)-shattering, it provides a beautiful base. This subbass region is responsible for a sense of spaciousness and ethereal playback. Those are two of Project M's strengths which I will cover more in technicalities. So, not a set that's necessarily focused on techno and hiphop, but it can do those respectably too.

Attack: Capable. Snappy, athletic, elastic, quick, effortless. It never feels stressed even in the craziest of bass lines. It unpacks information and presents it with sense of immediacy and urgency. As I said before, incredibly capable bass overall. Movement of the DD's membrane must be so well controlled.

Decay: Natural and plentiful, but wonderfully smooth and honey-like. No graininess, weird fluctuation or unexpected variance on same notes. Each note tells a story of its own. Just what a DD is supposed to do. This is where BAs just cannot compete – at least not in Project M's price segment or, heck, even at twice its price. It can do everything from wild electronica subbass decay to the intricate bass guitar solos.

Boominess: Nowhere to be found. This is often an achilles heel of sets that try to do it all by raising the midbass to achieve fake punch and muscle, while making DD's work way too difficult. How DITA have achieved it here is beyond impressive and it makes me so eager to hear their next creations.

Bloatedness: Not an issue. Low mids are sculpted wonderfully and allow for an overall very transparent signature despite intentionally taking a bold risk by cutting the upper midrange as much as they did.


Mids
(some songs I used: Creep by Haley Reinhart, Rosita by Coleman Hawkins&Ben Webster, Vidda by Ole Edvard Antonsen, Long after you are gone by Chris Jones, Writing's on the wall by Tom Ball, Dream on by Morgan James, Lonely island by Amble, Exhale the ash by Ulcerate, Free bird by Lynyrd Skynyrd, Eyes don't lie by Tones and I, All about you by Sophie Zelmani, Shivers by Ed Sheeran)

Timbre: Getting this right is crucial in overall acceptance of any set. Always a sensitive topic. Timbre is not an easy one to unfold and pack into these little forms we call words. We also have a different understanding of 'correct timbre'. Hearing the instruments in multiple settings and played by different artists is a must to really get familiar with their intricacies. On the M, it starts off well in the bass and most of the midrange before derailing in treble. The treble makes higher-pitched instruments and their overtones sound just a tad off and wonky. Most noticeable on cymbals and brass. Even those would be passable in isolation, but feel incoherent to the rest of the mix, thus sounding out of place ocassionally. Piano changes character from the lowest to highest octaves. Just how annoying one finds this is down to music they listen to and sensitivity to timbral accuracy.

Forwardness: They aren't forward in their presentation nor in their placement. What is special, though, is just how weightless they remain despite that. While carefully threading in the background, they keep their composure and fill out the audible space.

Clarity: While not the best I have ever heard, the fact mids stay as clear as they do despite the chosen tuning approach is amazing. Not much detail escapes you. And it's all supported by healthy fullness – more in note weight section.

Vocals: Neither male nor female vocals lack much, but as expected, they won't soar as freely as on sets with more aggressive pinna and high mids. Therefore, my decision whether I enjoy the vocals or not is rather difficult and I have no straight answer. I enjoy the lack of shout and sibilance, but at the same time miss some of that soul and bite. Singer-dependent for sure.

Note weight: I'm most sensitive to how the piano is played back. Hearing a grand piano live you can tell just how much body each note carries and how rich it is in under- and overtones. Note weight is one of those risky topics and it quickly segregates the field in two camps, those that prefer a thicker, rounder note weight and hence a more analog approach, and those preferring all-BA sets because those usually have a quicker, less hefty character and a more digital sound. Mind, those are very very severe simplifications of this layered, 50-shade-of grey topic just to carry my point across. Project M strikes a balance of note weight throughout the range, except treble, where they can get all haywire and crazy. Elsewhere, it's a happy medium, not the thickest and fullest of notes, but they don't seem hollow or lacking substance either. I am a fan. That said, this won't be my set of choice for piano arrangements.


Treble
(some songs I used: Vidda by Ole Edvard Antonsen, Want by The cure, All about you by Sophie Zelmani, Morning bird by Sade, Animali in Marcia by Gianluigi Trovesi, Ain't no love in the city by Robert Haglund, Barbados by Arne Domnerus, Oh Dear by Sophie Zelmani, Liberty by Kerenza Peacock&Timothy Ridout&Hum Watkins, Shivers by Ed Sheeran)

Crispness/sharpness: A mix of multiple qualities hidden all the way from upper mids high up into treble. There is no straight-cut rule to tackling this and having it fit all ears and preferences. Project M is a special blend of crisp and sharp. While it's not offensively sharp, it's incredibly crisp. That serves as a great tool to aid the poorer recordings. Old stuff that sounds muffled and poorly mastered gets invigorated. However, on the contrary, those songs that need no brightening will be just as affected by this crispness. That can result in a highly detailed listen, or so you think at first before fatigue creeps in. This mid treble tuning ends up sounding very planar-like (or at least, planars of the yesteryears) in that it's certainly energetic and attention-grabbing, but soon gets overwhelming. This hobby of ours is weird in that age has a huge impact whether we like it or not, thus older ears may appreciate this better.

Sibilance: Very safely avoids it. Even in Shivers by Ed Sheeran which is recorded insanely crispy and bright even in all the risky areas. And while the M skillfully avoids sibilance in this song, it cannot escape sounding grainy and too enthusiastic in mid treble.

Naturalness: Due to the tuning I struggle calling this natural. I have yet to hear a concert or any live performances sound as aggressively bright in the upper register as the M. The treble quality itself is very enjoyable, though.

Air: Extension is not the greatest ever, but this will sound airy to most due to what happens before the 15kHz mark. Not an issue at all. In fact, I would like to see less of it because it can get a bit much with the mid treble excitement.


Technicalities

Soundstage
: A very touchy subject with no objective truths, highly affected by source, and incredibly different from one pair of ears to another. Skipping the effect of our pinna, as IEMs do, is both a blessing and a curse. One has to figure out for themselves what tricks their brain into placing objects furthest away from their actual point source. While the M doesn't expand too much to the sides, it feels sufficiently deep and tall to avoid me calling it closed in or cramped. Soundstage-heads, look elsewhere.

Imaging: Potentially the most crucial technical aspect in IEMs. And this is the reason why I feel soundstage might be just a bit overhyped. The outer edges of where the sound is coming from are not as important to me as their localization and size of the image. Give me a more intimate soundstage with better presented individual sounds over a huge soundstage with more diffused imaging any day of the week. And yes, the M separates tremendously well despite not expanding too wide. Some of its imaging is down to just how forceful the treble is, but I believe it's mostly a function of great drivers and fantastic implementation.

Detail retrieval: A subject that should be cut into even smaller subjects to cover more easily, but I will try to explain it in one. Macro- and microdetails is how they are usually referred to. Macrodetails will be the larger items we can look into. Maybe something like a clap. How well is that clap separated and detailed in its onset and offset. While microdetails would mean delving even closer into that clap – how crisp is it, any minute detail that stands out, possibly the person is wearing rings and those hit each other when clapping. Project M passes with high marks in both micro- and macrodetailing. Especially the bass is so nuanced that it really made me appreciate certain bass lines even more. It also opened my eyes to what is possible at this price range while making me so curious about the high-end and just how far they can take the bass in this physically very limited space we call IEMs.

Cohesiveness: Such an important and often overlooked quality. We focus on bass, mids, treble, etc., but do they work together as a team or is it a bunch of talented individuals pulling to their sides? And Project M gets it slightly wrong. It's as if the attackers (treble) just don't feel like running back to help in defensive duties too. Bass and midrange work together wonderfully, but that is to be expected since they're driven by the single DD anyway.


Extra

Fun factor
: Another tough one to simply close by saying either yes or no. It's fun until a treble-heavy song comes on. It's fun at low to mid volume and nothing but pain at higher volumes, even though the bass edges you on to turn that knob higher.

Q: What kind of source to pair it with?
A: Warmer preferrably. The DX180 is okay with all its neutrality, but does nothing to address the elephant in the room, the mid treble.

Q: What genres are its strength/weakness?
A: It's not as much down to genres as it is to individual songs and their recording & production. I can enjoy it with most genres, but would prefer more subbass for techno or hiphop if that's your thing.


Summing Up The DITA Project M

Thanks to the gentleman that is my friend who trusted me enough to lend me this IEM for me to have a go. Project M is a unique beast. Most are focusing on its treble, and I feel that can be the thing that both makes or breaks someone's experience with the M. It's right on the edge for me and requires careful musical choice. What stood out to me was the near-perfect bass and the fact the midrange works well despite the dip. I can recommend this one to certain audience only (and those that have the cash to risk not liking its sound, but buying it solely for the looks). As for others, wait and see what DITA comes up with next.


Thanks for reading and stay wonderful.

New Head-Fier
Project M

I tested this set with a variety of aftermarket tips, and found that the included glow-in-the-dark ones by Final are more than adequate – the timbre of snare strikes and bass notes are better extracted from Project M via the Final tips, which is quite impressive. To see that a company has given consideration to supplying a set of tips which takes some of the guesswork out of using their product, is a welcome development. Ergonomically, the resin casings are designed very well, and are one of the best fitting sets I’ve worn, not to mention very interesting to look at, when inspected closely. The

Their combination of a proprietary PM1+ 9.8mm dynamic driver along with a Knowles Balanced Armature driver is very effective at conveying a reasonably wide and convincing soundstage – this is purely speculative, but I suspect that to have aimed at tuning for a wider effect might have compromised the coherence of the overall sound, so I think Dita chose well here. I revisit Edition Studio Masters version of Steely Dan’s ‘Two Against Nature’ very often for analytical listening, but it’s worth mentioning again, as this album sounds simply sublime with these IEMs – a true high fidelity experience, which is what the endless dragon-chasing in hi-fi is all about! The bass and kick have the right amount/proportion of impact, without being overdone, while hi-hat and cymbal taps are captured perfectly.

For my own curiosity, I conducted an A/B comparison between Project M and an IEM (which will remain nameless) from the +$200 category, and though the test parameters were quite loose, I’m now convinced of the merits of shopping in the +$300 category where Project M resides. The cheaper IEM benefited from Project M’s premium MOCCA cable, but simply couldn’t compete with the technical proficiencies of its more expensive opponent in this informal test. Dita deserves praise for designing this cable to be switchable/modular, thereby ensuring the buyer is covered with 3.5 and 4.4mm terminations.


Navigator

To conduct a comparative test of this $300 dual DAC dongle, I pitted it against source components that are roughly in the same price range: Tempotec V6 DAP and Chord Mojo (What HiFi Magazine’s ‘Best DAC £300-£500’ award winner, 2020).

With a variety of well-produced rock songs selected from Tidal (Tool - Pneuma, Sons Of Apollo - Labyrinth, Yes - Mirror To The Sky, Dream Theater - Pale Blue Dot & Metropolis Part 1, Felipe Andreoli – Metaverse), Navigator delivers plenty of punch to the tested drivers (Dita Project M) selected for this source showdown. Background noise/hiss isn’t an issue with Navigator (which can’t entirely be said about the Mojo), and it presents a clean and spacious, balanced sound, with no deficiencies in resolution. The V6 comes quite close to matching the Navigator, but can’t quite provide equivalent clarity and capabilities.

I also compared Navigator against a dongle from a much cheaper category – iBasso’s $60 DC03 – and though the latter is clearly less impressive, for those who might be interested in Project M and want to employ the principle of prioritising headphones over dongles, the IEMs sound absolutely fine with this cheap dongle, albeit not as micro-detailed as they do with Navigator.
