Ok, Dunu Mirai is very tip-dependent. After trying some new tips this is a much better and more consistent iem, that I’m more impressed with. Yet, that treble could easy be piercing. I’m enjoying it now.

The funny part is that mmk3, prestige ltd and dte900 all graph brighter than dunu mirai.

On paper - definitely yes! The DTE900 is very versatile because it has switches that work and make a real difference to the perception of the sound and this makes it the best value of the other TOTL level. This is the only IEM that made me cry on this album’s Up/Down setting:

I am not sure why, I think a lot has to do with the nozzle length. It’s a lot better and sounds appropriate to it’s price with the right tips.
Ohh quick unboxing video of a beautiful product if anyone is interested.

Hey, thanks for the write-up! I appreciate the support, and I thought I could help explain some of what you might be hearing.
As you observed, the Mirai is quite tip dependent. Ear tips primarily affect the extremes of the frequency spectrum. This makes sets that have extreme high frequency extension, especially via peaking in the upper-treble to achieve greater technical performance, more dependent on ear tips. There are several types of tips included with the Mirai, the ‘safest’ ones will be the white-clear silicone ones with the DUNU logo. Those reduce the treble regions pretty consistently across the board.
Nozzle length also plays a role because, as insertion depth changes, the natural resonance from the ear also shifts (usually a deeper insertion pushes it higher in frequency and with less energy). You can see this if you play around with insertion depth on a measurement coupler. Basically, longer nozzles will inherently lead to more variation when swapping between different tips.
You’ll often see more discussion around ear tips making a ‘big’ difference with more expensive sets. Part of this is just people wanting to explore every avenue when they’ve sunk that much money into a set and confirmation bias. But the other reason is that more expensive sets are usually the sets that are hitting that high frequency extension, and they usually do this via tuning methods which increase the size of the nozzle too. Hopefully this lends some insight if anyone is curious about why ear tips matter (and when they tend to matter more)

I can lend some thoughts on this. Basically, I don’t really subscribe to the idea of IEMs being tuned for specific genres. Every individual song is different within a genre: mastered differently, emphasizes different frequencies, and so forth. Yes, there are characteristics that overlap - for example, certain genres will use certain instruments more - but I’ve found genre to have little bearing on my enjoyment between sets because of these other factors.
The song itself and how a tuning handles individual instruments/sounds matters a lot more to me. And that’s not to mention individual preferences for tuning; let’s say most people find that that more mid-bass is ‘good’ for a genre like rock/metal. But someone likes rock/metal music while preferring a sub-bass focus. How do you reconcile that? My experience is that it’s usually the sub-bass focus that takes priority for this listener because preference matters more than being ‘correct’.
I think it can be easy to say, “this doesn’t work for ‘x’ genre” or “this was made for ‘x’ genre”, because who doesn’t want a quick, surefire answer? But when I tuned Mirai, I had to consider factors that are more granular than this, and these are the factors that I think people should pay more attention to. I know I’m circumventing what you’re saying to some degree, but basically, it wasn’t about genres to me when I was tuning it. Of course, everyone is free to choose their IEMs based on how they’d like!

Plutus Beastie is interesting 
Seems like it could either be something fresh and fine, or a real trainwreck

I agree here. There is no 100% ideal IEM for rock and metal (guitars and cymbals are very difficult to tune, excellent dynamics, layering must be at the highest level, etc.). Also, there is no 100% perfect versatile IEM that can do everything. Even if there is, there will always be someone who doesn’t like it 
. I applaud you for your efforts in creating the Mirai, technically I assume it is very good, or at least meets the asking price.
By the way, I like more sub bass over upper bass for metal, but still have some amount of upper bass. Cheers, happy new year and success in your endeavours!

agreed with you. this is probably the best answer you can give, and the “preference thing” for how certain genre should sound like is the the main point not the question of whether if x iem or sound signature can play certain genre or not. not to mention the way certain tracks were recorded , the rooms, the equipment etc differed to others noticeably.
Here are some song examples, i picked well known songs in particular.
they Sound pretty dark, rolled off and kinda lo fi. all have that early 13k 14k roll off that makes the replay to have less resolution overall. there is no bite to the guitars or any transients in general because the upper harmonics were cut off. You might like this sound and think its “correct”, "non fatiguing " hence metal should sound like this but as as you can see, on faster songs it gets muddled up and turn into soup pretty fast( listen to the later track from ne obliviscaris). i personally don’t like this sound but so many do.
another example of something in between
This one got sharper transient hits and fuller midbass hence punchier drum hits in general, probably because the monitors they used had lower group delay on the woofers and the time for the woofer to vibrate and be done was lower compared to smaller monitors. Also its much more “flat” sounding comparing to the last tracks that were more downward sloping so this results in a brighter and more shrill cymbals compared to he former songs (this also improves the positioning and imaging of the instruments). You might think this is how metal should sound like, balanced and slightly bright tilted to get proper imaging yet the transients stay sharp and punchy but the last sound engineers who produced the former songs would disagree. I personally like this the best
And then you have songs like these
Sounds quite anemic and noticeably bright compared to other songs (the beyond creation and black dahlia murder in particular sound shrill and strident). Subbass is more boosted over lower mids(specially on the first song from archspire). Lower harmonics of bass guitar, snares, rhythm and lead guitars were cut off. But why? As we know, more bass=more congestion and the sound engineer knew this so they eqed instruments on the mix on these particular tracks that are “faster” and more prone to congestion to be clean and mud free. You might argue" thats" not how snares sound like irl, or where is my bass guitars" but this is how it works better for these faster songs for the price of getting a more shrill sound in general and faster fatigue.
And you have metal songs like these, you can afford to sound full, warm and cozy because its just slower and there is less bpm in there. Why you wanna cut the bass and boost the higher frequencies? to improve imaging on a slow song? No reason tbh unless you want an anemic fatiguing sound.
Does this mean all the producers were " wrong"? not really. they all liked the song to sound just like their ideal vision and tastes. you have 100 metal songs or any song from different genres in general, and all would have different production on them.(like i tried listening to kpop and got a few hundred songs by now 95% consist of female vocals, and some had mid to upper mid boost, some had subbass boost and less midbass emphasis, some had all punchy bass no emphasis on subs, some were low res and rolling of pretty quickly and some extended strongly up to 21k+ to get a more resolute and sharper sound).
these are the differences in the sounds that personally makes me wanna listen to flatter sound signatures because they are just versatile, they aren’t the best at any music replay or “giving life to x genre” but they are the jack of all trades without doing weird stuff by altering frequency response in general (like boost in bass helps anemic songs and destroys other songs, or bright sounds helps darker dounds but rapes the ears on other tracks, dips on treble to avoid sibilance helps some songs or sensitive ears but makes other more correct songs sound darker or wonky to some people and etc…) but someone else will disagree with me.

Are you aware that you have rated (among others) the Chopin ahead of the Variations, Dunu Sa6 mk2, Meteor, Performer 8…?

I think people think about price and driver count or drivers way too much in audio. You like what you like, simple as. I encourage all others to build people up and feel there is enough products and room in the audio hobby for all to share their opinions and all to feel valid.
I’m just sharing my opinion, not a universal truth. That’s the hardest thing for many to understand, there is no universal truth, it’s not black and white but a bunch of companies trying to make a buck who don’t give a damn about you, but are trying to feed their kids and buy their second Yacht. When you understand this…

In this world of audiophilia I have seen everything.
also those who non-stop promote a collaborative iem.
I don’t make a video of everything I get on my desk. I was impressed. This is a personal set, not a sample.

Shell design is beautiful and comfortable
Included case is classy, and pracitcal.
Cable is one of the best I’ve seen at the cost.
Great to listen to on hard days.
Great drums, and instrumentals.

Resolution could be better.
Is a specialist not a main set.
Not for treble heads
Metallic timber
This is a review sample sent from Hifigo. The opinions are my own, but I am going to try to express them in a clear manner after having had some time on them. This isn’t a set I would buy from looking a the graph. I’ve been highly disappointed in just buying the latest craze set, but this set is fully enjoyable for me and I am loving my time with it. I was able to chose what color I wanted looking at the shells. This set has created many memories for me.
Cute story I allowed my 7 year old son to pick which version he wanted and he picked blue. A few weeks later when it came in I showed it to him and he said. “That’s what I wish I could own when I’m an adult.” Suffice it to say the little guy is a big fan of the Plutus Beast, and for good reason, it’s crazy beautiful and classy looking.
This is a funny hobby. I have a watch case, and for various reason I keep 5 iems in this case next to my desk where I spend a big of time each day. Right now I keep the NiceHCK F1 Pro, 7hz Acoustics Supernova, Gizaudio Binary x Chopin, Aful Performer 5, and you might have guessed it the Plutus Beast.
Summary-
Iems just inject goey lovely music into your brain and it’s a special part of this hobby. But if you’re willing to branch out into the unknown and try something you might find something especially unique and lovely. The space and air of this iem is majestic, the richness to the iem is unique, and I feel it is very special but holographic and I don’t say that easily about many sets. It does something for me when I listen to music that I didn’t think would be possible from a set that is 100 dollars or less. It makes me enjoy music and satisfies me down deep with a fun awesome concert-like experience that is vivid and emotional in a way that I didn’t know that I needed. This iem lives up to its name and is a BEAST. Enjoyable analog feeling for those who need a beautiful set, that doesn’t need a recable or case to be bought. This is an easy recommendation for yourself or a gift to a friend. They’ll love it, and so will you.
But we don’t always need the same set to listen to music. It’s fun to have various beautiful easy-to-fit sets in part of your collection. And this is why I think the Plutus Beast is a treasure, not because it it perfect but in its imperfections and uniqueness make it stand out in this world of AI imperfections and writing and everything sounding sterile and docile, this iem is the analog to the digital and it satisfies the beast in me. For it’s price it is a unique set that is easy to fit in the ears, beautiful, and plays some tracks better than many 1000-dollar sets.
Any feedback is welcome.

Overall signature would be harmonious with a slightly dark tilt. Comes in a 4 x 4 box, and it isn’t branded or labeled. Just has a nice little case and a reasonable cable, that looks great. The cable is a little stiff, but not bad, just say that it does feel a little cheap feeling and stiff, it is beautiful and a nice iem.
The technicalities aren’t great, but the vocals are pretty solid and enjoyable. The fit is amazing. While maybe not better than other 200 benchmarks for me like the Quintet, Aful 5, and the Unicorn Choppin, it’s still very good and an easy recommendation and a clear 5 star, and the only 5 star I’ve given under 200 dollars… so far. It’s just nice, not just for the price but overall just delightful.
This iem is great on instrumentals and classic music and has a strong tonal balance. Female vocals are a bit too sweet and unnatural. Male vocals could be a little stronger but the bass response is great and the quality is very strong.
A 170-dollar set that doesn’t disappoint.
It’s a step above the Magic one in the quality of the bass and above the Nova in everything but the bass, If you have that 150 dollars and want to know what to buy and can’t stretch… this is a strong set, that I don’t think you’ll be disappointed by. I have a YouTube video on my channel if anyone wants to check it out, I’d appreciate the subs, likes, and comments.
