Letshuoer Cadenza 4

Disclaimer:
This is my friend unit, impressions are strait otta what I felt and I spent less time with them so you can take it easy.
My preferred sound:
neutral sound but with musical presentation(this describes itself not nuetral ). slight emphasis on bright or warm both works for me
equipment:
spinfit w1 tips and cyan ru7 dac/amp

sound:
soothing, melodic, musical presentation
bass:
It has nice sub-bass with good presence of rumble, mid-bass is adequate (little less compared to sub-bass) but
that doesn't mean it lacking either it is sufficient to balance other frequencies.
and I do find bass is little mellow/soft slam not the tightest, but attack/decay is still good though.
kick drums bass reproduce good however I would have appreciated if it has more slam.

Mid-range:
Not sure where to start but I found midrange to be one of the best I’ve heard in the price point.
vocals are clean and little forward, everything sounds engaging. male vocals got that weight and lushness, and female vocals sounds exquisite with crispness
guitar, violin, Saxaphone and trumpets sounds phenomenal with good layering.
had plenty of room for both vocals and mid-range instruments.
All if I can say about midrange in simple words, it sounds very emotional.

Treble:
treble is inoffensive/little relaxed yet still has good energy without any splashiness.
I played some busy tracks and it handled all of them without any struggles and never sounded grainy at all

Technicalities:
I wouldn’t say that the soundstage of the Cadenza 4 is huge but there is definitely enough room for all instruments.
It is above average, height, width and it has very good depth though
it has good micro and excellent macro details.
it has excellent tonality and timber.

Intro…

The Cadenza 12 was released as both the flagship IEM of the brand and the first in what was said to be a series of IEMs, the Cadenza. This was early in 2023, with a prototype making its rounds at Canjam quite a few month before that. While I didn’t get to spend a lot of time with the Cadenza 12, I did get to try it out and I have to say that it was my favourite IEM from the brand, although a little bright.

A year later, Letshuoer presents us with the second IEM in the Cadenza line up, this time at a much more affordable level (for most of us), priced at under $250, or $229 for those who pre-ordered, which is around 230€, that is a rather large difference from the 2000€ price tag of the flagship model. While the Cadenza 12 featured 12 drivers, the Cadenza 4 coincidentally (or not) features 4 drivers, that are a dynamic driver plus 3x balanced armature drivers.

So, let’s take a look at what we are getting from the brand for the much more pocket friendly price point of their new model.



Presentation…

The packaging and contents of the Cadenza 4 are certainly nothing to complain about in the price range, in fact, they are very similar to the presentation of the S15 that I reviewed not long ago and comes in at almost $100 more expensive.

The same grey outer sleeve, featuring just the make and model, with some basic specs on the back, slides away to reveal an even simpler flip top box in the same colour with “Letshuoer - Sound Alive” on the top in small white letter. This outer packaging is simple and elegant.

The flip top box is held closed with magnets and opens in the same “jewelry box” type way as that of the S15. There is a top layer, covered by a grey card envelop containing the user manual and other documentation, which is removed to reveal the IEMs sitting underneath.

The bottom half of the box is a slide out drawer accessed from the front that contains the rest of the accessories, which are a black screw top storage/transport case, the cable with interchangeable connectors, 2.5mm, 3.5mm & 4.4mm connectors for the cable and the disc style tip holder containing “balanced” and “vocal” tips, 3 sets of each.

The only real difference between the presentation of the Cadenza 4 and the S15 is the colour of the cable and the colour of the “vocal” ear tips, which are grey rather than blue.

I have nothing but praise for the presentation and accessories included with the Cadenza 4, making it a nice box opening experience and giving a feeling of a set that has been cared for.



Build and aesthetics…

While the Cadenza 4 do share a similar shape to the Cadenza 12, this is as far as the similarities go in build. Where the flagship is a completely metal shell, the Cadenza 4 opts for a 3D printed shell with a CNC machined faceplate in aluminium with a matte finish. The shells are white which leads to a very elegant looking set of IEMs that are not overly shouty but look, and feel, to be of good quality.

The 3D printed shell also helps to reduce weight, with the Cadenza 4 being a very lightweight and comfortable IEM, at least in my ears.

The included cable, stated as being a 392 strand silver plated copper, matches the aesthetics of the IEMs, with white and matte aluminium hardware that also matches the aesthetics. While I am someone who prefers fabric covered cable personally, there is no doubt that the included cable is of good quality and, as it includes all the termination options you may need, it is a perfect match for the IEMs.



Sound…

All tracks mentioned are clickable links that allow you to open the reference track in the streaming service of your choice (YouTube, Tidal, Qobuz, Spotify, etc.)

I am not going to make any comparisons in sound between the two Cadenza models as, on one hand, they are in totally different leagues, and on the other, I only briefly listened to the 12 in show conditions last year, so I cannot faithfully make any comparisons.

I will say that this is the 5th set of Letshuoer IEMs that I have reviewed, having tried a fair few more, and that each of their models has a different flavour to it, none of which I have hated. In fact, I have quite liked them and the Cadenza 4 is no exception. In fact, it may actually be my favourite tuning from the brand yet. It is certainly not perfect, to me at least, but the issues that I do find are fairly small and are lost in the overall performance of the IEM.

Anyway, I am getting ahead of myself, so lets go through my usual steps and start off looking at the graph in comparison to my personal preference target:



Before getting into the specifics, let me say that I found that I preferred the “Vocal” tips (the grey ones) for the Cadenza 4 and those are what I have been using for my detailed listening in this review. There is a sensation of more bass with the “Balanced” option but I found that the bass with the “Vocal” tips was plenty for my tastes.

In the subbass range and focusing first on “Chameleon”, there is enough rumble in the lower frequencies to appreciate the madness of this track, with a nice deep extension. However, the subbass is clean and not really boosted too much (enough for my tastes but maybe not enough for others that prefer more rumble), keeping this articulate a giving a very nice presentation of these lower ranges.

With “No Sanctuary Here”, which is not as overpowering in the subbass department, I find a very nice balance between subbass and midbass, with no real emphasis on either of them, with the low end of this song sounding very clear and decisive.

Moving into the midbass zone and using my midbass fatigue track “Crazy”, there is no sensation of the low end reverb becoming overpowering. It is noticeably there but does not hijack any of the surrounding frequencies, allowing the guitar to present those low end notes without becoming overly boomy.

While the midbass may be a little lower in quantity than many will expect, I find that it is really well balanced and does not give the sensation of missing any warmth in bass guitars, such as in “Elephants on Ice Skates” or in older rock tracks that usually benefit from a bit of extra warmth, such as “Whole Lotta Love”, where the bass guitar has a tonality to it that I find both pleasing and correct, at least to my ears.

Throughout the whole of the bass zone, details are good and I find they get even better as we move into the midrange of the Cadenza 4. In very simple tracks, such as “Happens To The Heart”, the details of the track, such as the breathing and slight vibration of instruments, are easily appreciated while the vocals remain full. In busier tracks, such as “The Room” by Ostura, the Cadenza seemingly keep up without any issues, again letting the details of each instrument shine through but without them being overly upfront.

As we climb into the upper mids, there is plenty or presence for both vocals and instruments, although some tracks can come across a little harsh in this recording. For example, “Crazy” that I mentioned earlier, can have a little too much emphasis on the vocals of Daniella Andrade and even a slight hint of sibilance. This is reduced by switching to the balanced tips, which moves the emphasis away slightly and places it a bit more on the lower ranges. However, it is not terribly harsh, unless you are someone sensitive to the 2.5 to 3.5k region, and I personally prefer the response of the “Vocal” tips.

As we move into the higher regions, there is a nice sensation of air and extension which maintains sibilance in tracks like “Code Cool” at a point I would consider neutral. In other words, it does not add or subtract sibilance to/from Patricia Barber.

The treble extension may not be the most extended treble out there but Letshuoer have done a good job of balancing the treble, allowing it to sound open and airy without sounding overly emphasized, harsh or too bright.

I already said that details are good throughout the whole range and this is added to a nice sensation of space between layers of vocals and instruments, as in the recording of “Strange Fruit”, where background details are noticeable and spacing between the vocal layers are well defined.

I wouldn’t say that the soundstage of the Cadenza 4 is huge but there is definitely enough room for instruments to spread out, although I find that in “La Luna”, the rear left guitar is pushed slightly more left and less back than on other sets. This doesn’t make for a worse presentation of the track, just different.



Conclusion…

The Letshuoer Cadenza 4 are a very impressive set of IEMs. As I mentioned earlier in the review, they may even be my favourite set from the brand so far. There are certain tracks that can become a little hot in the upper mids with the “Vocal” tips but this can be remedied quite well with the “Balanced” tips. I found that I could enjoy them even more with a couple of other aftermarket tips but I usually don’t go into aftermarket accessories in my reviews and try to focus on the included.

For the 230€ price point, you are getting a nicely built set of IEMs, that sounds good, performs well and is also presented in a way that I would say is above the majority of the competition in packaging and accessories.

These probably won’t be the correct choice for those looking for a bassy set of IEMs but for those who are looking for a good, balanced and well performing set of all-rounders, the Cadenza 4 are a very good candidate.

About Cadenza 4.

Letshuoer, the parents of the hugely popular planar IEM the S12 have a new baby for us.

Letshuoer provided this review sample to Audio Reviews Downunder for our honest assessment, and we would like to thank them.

Cadenza 4 is a 1 DD 3BA hybrid. The company also has the Cadenza 12 which is a 1DD 11BA flagship IEM. Cadenza definition: Technically brilliant sometimes improvised solo passage toward the close of a concerto.

In the box we have the IEMs which I find understated and elegant. A lot is made of the look of an IEM but once they are in your ears…out of sight, out of mind!

The cable is just great, Soft and substantial with a great feel, left and right marked pin connectors and modular at the other end with the three usual sized male connectors. This is one of the first cables I have not been tempted to change with some of my collection. Also included is a hard plastic round case with a screw cap. Solid and durable it also feels quite soft and tactile. Just don’t let the dog get hold of it!

The supplied tips are average and below par compared to those supplied with the dearer S15 planar.

The fit of the Cadenza works well for my ears. The body is molded and shaped to the ear cavity as opposed to a simple cone shape. (It is similar to the Kinera range) This gives me a good fit with my ear shape and has the advantage of good noise isolation.

Drivability was good. I used my Hiby R3 Saber DAP with high gain and while a volume level of 36 (which is average for an easy to drive IEM) gave a good sound level, I found the Letshuoer scaled well when I boosted the volume into the 40’s. The music grew in power and grandeur without any corresponding harshness or distortion. Similar to the way my Hidizs MP145 planar performs.

The Sound

Remember these are my impressions and may not relate to all ears or ear canals!

When you first listen to Cadenza 4 you should be impressed by the superb balanced and musical presentation. This set is the best hybrid I have spent time listening to this year. Every part of the sound spectrum is presented so correctly that you just get lost in the music and forget to analyze! In this way it compares favorably to my number one set, namely the Hidizs MP145. Usually, I keep the MP145 tacked away when I am assessing a new IEM but in this case the Cadenza demanded “get the Hidizs out…I can take it! “

Starting with the bass, the kick drums do kick with a visceral punch that you can feel. Drumsticks tapped on the side of the snare are tactile and realistic. Sub bass is omnipresent in just the right amount without overpowering the Mids. Bass guitars have weight and depth and upright basses sound deep and realistic with real gravitas.

The midrange is spacious and uncongested with good tone and some warmth. Vocals are presented just right, neither to forward or recessed. Acoustic guitars sound realistic and detailed. Female vocals are rather delicious, natural and captivating. Male vocals have correct timbre and tone to my ears. My most problematic close miked vocal tracks that can sound harsh and troubling with some tunings, survived analysis nicely.

The treble has energy and clarity and is never overdone. Once again, we get back to the balanced sound of the Cadenza. Sure, it could have more sparkle, but would it dominate the mix? To me, it sounds just right.

Soundstage and technicalities now. The soundstage has good width and depth and I rate it as above average. Imaging is very good with Cadenza and placement of instruments within the soundstage is easy and accurate. Detail retrieval, while not TOTL is also adequate to my ears with plenty of small nuances and minutiae audible. Put it all together and you have a seamless symphony of sound.


To sum up.

Did Cadenza 4 surpass my Hidizs MP145 as my favorite? Close but no. I still love the planar. But the Letshuoer takes it place as one of the best balanced and musical listening IEMs I have auditioned. It gets my strong recommendation
