Yeah thats a pk shell. Not sure if its the original shape/size (but in metal) or if its one of the other variants.
That Nicehck is a bell shaped bud, those tends to be comfortable at least but not very good fit.
I suggest trying the Qian39, if you feel the same about them, then buds dont work for you.
You wonât get the same amount of bass as an IEM but a good fit defo helps, I struggled with fit too at first my solution was NiceHCK Black Silicone Rings + foams to tune, hope you manage to get a fit as buds are great in fact I use them more than IEMs these days 
What one were they talking about?
Switching over to the LETSHOUER Mystic 8 on some tubes and DX340
Definitely more my speed.
And some Tea Party
Thanks!
I also imagined the Onyx might be too smooth for C12 , thanks for saving me the time and money.
So far i prefer very transparent and linear sources with C12, also as you said, to spice it up.
Try C12 with 3.5mm Stock cable If you did not yet.
Depending on source aswell 4.4mm is a bit too smooth to my liking.
Would you say the DC07Pro is wide and spacious sounding? I Heard very contradictive descriptions ranigng from wide and spacious to very intimate 
Very 3D on the iBasso DX340 for stage , also just a FYI higher impedance loads from your source cut down on the top end , i checked and measured. So the Onix XM5 with its huge output impedance would effect sound even more.
Thanks, i also found that out witht the impedance.
G5 with its >0.1 Ohm is my favourite so far, together with XP2BalâŚcanât find output impedance of this one but it must be very low aswell
Donât quite unterstand synergy with DC07Pro as you were talking about DX340 instead 
The NiceHCK, I believe its the EBX25.
A rare Written Review for the Letshuoer Audio Cadenza 12
Cadenza 12 - A True Virtuoso
Pros: What I liked and Why:
Amazing shell fit and comfort for me were top notch.
Premium modular cable that paired extremely well with the IEM
Bass 0h that Kevlar driver in combination with. how well it was tuned inside of that titanium shell. makes bass magic. And what I liked about it was how deep it played.
Incredibly textured has a real woofer sound with fantastic decay and the secondary harmonics are some of the best these years have ever heard. Itâs a really stand out driver. But I also really liked about the bass was the fact that it was authoritative, but never overbearing when. the music had information in it that woofer came to play but it never was boomy. And the glide into the mid bass was a very nice mix to give some punch and some kick especially to instrumental like guitar piano percussions Quite stand out very enjoyable.
Just the overall tuning. Definitely not neutral boring with a bass boost. No, not at all. Itâs organic, natural, musical, nuanced, detailed, one word. Flawless.
Macro and micro details not to be confused with resolution. Here Iâm talking about how well the C12 does in the quiet passages. how well it portrays emotion between the soft passages and louder passages and overall in the track. eliciting emotion as the producer or artist intended
Itâs lively and dynamic with music. alongside amazing clarity and resolution.
From the lowest octaves to the highest end notes, the C12 can layer stereophonic base to overlapping the busiest passages with an effortless quality.
The 3D stage is just not a talking point. Itâs a huge deal. to get the IESMâ to simply disappear is a major feat. Well, some people may hear this as being an intimate stage.
You have to wrap your head around what the C12 is actually doing. and the C12 does this incredibly well.
Think of it this way. It portrays. the music just as the music and nothing between you and the emotional response elicits.
You canât help getting down into the music as it were. I canât help but having a bit of a flashback to the original EJO 7 and the Magic it did with the stage.
While I found the EJO 7 was more distracting because it pulled you away from the music with just how much information was given to you.
The C12 does this differently where it does give you all of that 3D stage, but it. does it in a way that doesnât pull you away from the music, and instead it does the opposite. It engrosses you. It engages you. into every track you listen to.
Forget trying to listen to this, IEM. All you get is just music. Itâs really hard one to review. because youâll just find yourself drifting and listening to it in a critical way, trying to hear how it sounds. Itâs one of the more difficult ones I have ever had to listen to and share my observations on.
Itâs just done in a musical way. A sweet way, I donât seem to mind that at all. In fact, it was just kind of engrossing to listen to whether it be jazz, rock, hip hop, Classical, reggae.
The C12. is a darn good all rounder.
Cons: What I found for Me Subjectively Could Have Been Done Better
While I certainly appreciated the unboxing. especially with this. level of price tag I did find some of the things like the metal plaque may have been a bit overdone a tad too much I would almost say. Wasteful.
That cable, while a beautiful pairing, did remind me of the. empire years Evo, a perfect. pairing cable slash IEM combo But what I donât like about the stock cable was it really was a bit stiff and unwieldy. and while it didnât tangle or get bunched up I found that it was just a bit too micro-phonic. though I never did switch it out because it sounded wonderful with the cadence of 12. I. kept wishing every time I picked it up. that I had a softer, more pliable cable. My choice. would be the Effect Audio Eros S2.
Now, maybe itâs because Iâm older at 54 and I donât hear as much, probably in the top end registers as say younger people might find in the top end, the treble was certainly enough for me. though sometimes I would wish for a little bit more sparkle and details.
And while I didnât find I was missing anything until after I did some comparisons to the Vision Ears. EXT Mkii and the Alpha Omega - Omega, where I noticed the EST Drivers on those 2 other IEMâs added in some special harmonics to the trailing edges of symbol strikes. Something that the cadenza 12 wasnât doing as well.
One thing I will say is that? for my time and usage. I donât have any scratches or blemishes on the shell. Seem to have held up extremely well and been quite durable.

LETS PUT THIS INTO SOME MUSICAL CONTEXT SHALL WE:
âMediterranean Sundanceâ Al Di Meola - Acoustic Guitar 
Amazing 3D stage, stand out instrument separation & placement of the various instrumental in their own space.
One huge take away was how well the cadenza 12 layers the notes. Letâs each note layer over top of the next for a clean, unmasked playback, highly resolving and detailed.
" Master Of Puppets" by Apocalyptica
This is a track where the four cellos play Metallica. I. wrote down just wow, even without EST drivers in here Iâm not sure theyâre really needed The top end travel is a combination of beautiful timber of the cellos. The C12 pulls down low for pitch perfect instrumental super. articulate top end very powerful and smooth.
"Spanish Harlem# by Rebecca Pidgeon -
Wow, talk about getting lost in the music. The cadenza is so transparent, so magical in this playback, you do not hear the IEM You just simply hear the music.
âBass & Drum Intoâ Live by Nils Lofgren -
The texture of the base, the attack and the decay was simply sublime Some, if not the best, base I have heard from a single dynamic driver. I am. I think the Sonion BAâS are also adding in some texture into the lower octaves as well, giving the cadenza 12 a unique and. special-bass presentation.
The 64 Audio Volur, The FATFreq Grand Maestro, and the Omega are also there and the C12 is playing with the big bios!
âLife Goes Onâ Ezra Collective
Perfect punchy bass instrumental is so well done, fun and engaging playback. Head bopping, air drums and toe tapping. All three are going to happen at the same time when you listen to this track.
âJuliaâ by Sixpence None The Richer
Female vocals are so clean and more importantly, pitch perfect to my ears. The C12 definitely is not a neutral set It adds in the perfect amount of colorization for a musically natural sounding set. Thatâs the difference. Is it balanced? Yes. And the fact that the base, the mids and the treble, all get their space to play in a harmonious way.
âFrictionâ The Crystal Method - EDM
Big FAT and Punchy Bass , Big Woofer Sound and a so smooth midrange and slightly relaxed treble can let you turn this UP and chill out!
âSympathy For The Devilâ 50th Anniversary Edition by The Rolling Stones
Here again another fabulous recording - anyone says the C12 has a intimate stage I would suggest change sources or ear tips, because one thing a Stones recording does is BIG SOUND , BIG STAGE!
The C12 here is very 3D for me playing vocals in various places and instrumental all over your head space , wide , deep , and with great height differences.
âDEEâ Randy Rhodes Studio Outtakes.
Great secondary resonances on the guitar plucks and finger slides - showing the Cadenza is not only musical, but also can be quite resolving, there are better playbacks from some other IEMâs of course including the Little Sister the Majestic 8,
The C12 does a darn good job bringing forth enough realism and nuances in this playback to recognise its ability to play at a top tier level!
âWishing You Would Stayâ by The Tea Party with Guest Holly McNarland A fellow Canadian as well
Here in this track I listen to some great rock but what I am listening for is how well the gear can replay not only the lead Male Vocals from Jeff Martin, but also Hollyâs vocals , in a lot of IEMâs that donât get the balance correct with too little or too much upper Mids for correct tonality , I am Happy to Report this LETSHOUER nailed it , both vocals are equally powerful and clear, without getting drowned out in the music.
Now that being said the Instrumental do come forward a tad more than I prefer being more forward in the mix, but the playback was powerful and more importantly musically fun no perfect.
I would rather have some saturation than the playback be thin and dry.
âUNTIL THE ENDâ by Rustage some RAP
Here is where the slight forward mids really come into play , making vocals stand out and the bass has no issues keeping up. Yeah I like RAP on the Cadenza 12
âSo Whatâ Miles Davis and John Coltrane - JAZZ
Here is where the non clinical persona of the Cadenza really comes into play. Instead of thin , dry and boring you get lush and musical.
Would I have liked to hear more bite on the trumpet - YES but for Jazz and chill the C12 is wonderful to listen to.
So I have gone through a wide gamut of genreâs and cant find too much fault in the musical replay when it comes to all typeâs of music - seems the Cadenza is a very good ALL-ROUNDER after all!
How about a few comparisonâs:
VS ALPHA OMEGA - OMEGA $2699 1 DD 4 SONION BA 4 SONION EST - Tuning Switches
Here is how I heard the differences:
C12 itâs more forward in the mids and vocals Base is punchier with a bit more mid-base emphasis over sub-bass.
The Omega It has much better balanced overall presentation. So less forward meds. And here the EST trouble comes out to play in their special way. So I found the treble to have nicer details on the Omega. And in the bottom end, the base is more visceral, deeper, a bit more sub focused. And again, more balanced, more in a role equal to the output of the mids and the highs.
Downside. of the Omega is the shells are considerably larger, as is the nozzles. So fitment for some is going to be an issue actually for probably many people unless you have. years that can take the beast.
Now, after this, Iâm going to compare it to the Vision Ears EXT Mark 2. But I did make a note that the Omega is the most balanced out of the three. It has the deepest bass and the most natural mid range.
The Cadenza 12 has the best base texture in the lower base and the mid base.
I found the Omega was also the most resolving. Brought out the most details, especially in the treble. And it was the most natural organic sounding out of the three.
The ESTâs in the Omega have that special sauce with the ESTâs implemented so well and give that special top end zing and sparkle. that the Cadenza 12. doesnât quite have.
VS VISION EARâS EXT Mkii - $4199 List Sale $3799 2 Dynamic Drivers 9.2mm and a 6mm with 4 SONION EST Drivers.
Here I found the. Ext to be a very balanced IM as well, with more focus on the top end and less so on the bottom.
Bass is still punchy and present when the music calls for it, but itâs a more mid centric with an upper registerâs emphasis profile.
The C12 in comparison, I found to be the most forward of the three, especially in the mids mid. Most mid-base energy. as well.
The C12 has the most relaxed trouble out of the three, and is probably the most mid centric. with an emphasis on the upper mid range where you get to really pick out the vocal details more than the other two.
The EXT has some great treble extension and resolution for strings and acoustic and thatâs its special sauce Overall, I found the EXT to be very natural sounding in its tonality and less coloured. than the cadenza 12.
CONCLUSION:
Wrapping up this review my time. with the cadence of 12 was a pleasure. It is. a surprise when I. heard it being described as a neutral sounding set I was picturing it as. boring and sterile, but that is completely not the way I heard this set Itâs musical, Itâs lush, It has some nuances to bring out the emotion in the music. It has fantastic three dimensional stage in all axis, width, height and depth.
Thereâs a lot of special sauce going on with this one.
I think itâs definitely worthy of consideration for a solid top tier all rounder. And thatâs something we donât sometimes see in the kilo buck. IEM range where you see some wackadoo tunings trying to stand out and not too many tunings with this kind of smooth frequency response.
I think what the cadenza 12 really brings to the table is a musical sounding set with not a lot of flaws.
First class unboxing cable, case. worthy of its asking price. Does it compete with its peers? Yeah, I think it does.
Letshouer wanted to make a statement with this IEM and quite honestly, I think they Succeeded.
This album from your test has a slightly bad recording. 
With acoustic guitars for layering and dynamics I use this:
For concert performance:
For transients, speed:
Great review! 
Talking bout getting lost in the music
âŚcheck this with C12 If you still got it with you 
Love to really crank her voice in the beginning
Thatâs why i prefer very responsive volume knobs compared to buttons so i can crank it up and lower it again really quick before i blast my ears
Another track i have used for years is Tricycle from Flimm & the BBâs
nice one! 
Wow, this is an incredibly detailed review! The Cadenza 12 really sounds like it nails that immersive, engaging experience, especially with the 3D stage. I love how you describe it pulling you into the music without distracting you. Can definitely see how the Cadenza 12 could be a top contender for audiophiles looking for a dynamic and all-around musical experience!
Thanks , yeah that one different that I heard it being described as, and it certainly surprised me.
Aye me too in a good way C12 
Finally finished my IBasso Audio DX340 review and it was a pleasure to do it.
Killer Flagship DAP!
