LETSHUOER CADENZA 4 vs. SIMGOT EA1000 Comparison Review

Two IEMs that cost around $220–$250 are the Cadenza 4 and the Simgot EA1000. Although they differ in important ways, they both provide excellent sound quality.

Additionally, they differ significantly with respect to other technical details. While the Cadenza 4 is entirely composed of 3D-printed plastic, the EA1000 is constructed of metal and features replaceable nozzles. The Cadenza 4 weighs less than the EA1000 and is smaller.

TUNING OPTIONS 

The EA1000’s SpinFit CP145 and the Cadenza 4’s AZLA SednaEarFit Crystal were utilized for this comparison. I tried the CP145 again on the Cadenza 4 since it is very vulnerable to tip rolling, as I had discovered before. In the final section of this comparison, I have discussed my results. The Cadenza gets four additional bass frequencies from the CP145 tips, which is still less than what the EA1000 produces.

The EA1000’s sound is affected by tuning nozzles. For the EA1000, I recommend the golden brass nozzles; they work well with everything. If you want to know more about the nozzles, you can check out my EA1000 review.

LISTENING IMPRESSION 

The RME ADI-2 DAC FS and the topping A90 amplifier are the supplementary pieces of gear. Using the Topping is more practical for me, even though the RME sounds great on its own.

In The Mountains by Espen Eriksen Trio 

The fourth cadenza begins with a pleasant jazz trio. Although it’s light in weight, the standing bass is fantastic; it has just the right amount of presence and sharpness to satisfy my ears. The piano is both articulate and full-bodied. The treble is natural, and the percussion is lovely. The soundstage is often rather expansive, and the image is second to none.

The EA1000 has a lot deeper bass, yet it has excellent sound quality, clear definition, and a remarkably realistic, three-dimensional impression. Compared to the Cadenza 4, the soundstage here is noticeably larger and more expansive.

 Jambi by Tool 

The guitar riffs in Cadenza 4 have a great feel without being too aggressive. The bass has excellent definition without being overbearing. In this mix, the vocals really shine. The sound is both spacious and easy.

EA1000: The bass has more bite, and the vocals stand out even more. On rare occasions, a touch of sibilance does appear, though. Beyond that, everything seems fantastic.

Smile by Pearl Jam 

Cadenza 4: The bass is well-reproduced and has a fair amount. You can readily make out each instrument’s sound on this rather hectic tune, thanks to the excellent instrument separation. There is no sibilance, and Eddie Vedder’s vocals are audible.

EA1000: Compared to the Cadenza 4, it has a somewhat busier sound. The EA1000 feels a little more dynamic and has deeper bass, but other than that, they’re very comparable.

Black Crow by Cassandra Wilson

Cadenza 4: The image and separation are top-notch; the depth and spaciousness are accurately conveyed. While the vocals steal the show, the bass drum isn’t far behind.

EA1000: The bass is broader and more resonant, giving it a slightly booming quality and making it sound extremely spacious. The voiceover is distinct and audible.

Some Day My Prince Will Come by Coryell-Coryell-Vitous 

Cadenza 4: The performance is highly balanced. Everyone and everything is being nice and having fun.

EA1000: The sound is expansive, lively, and organic. Warmth on guitar and a deeper bass. The space seems more open.

Desert Island Disk by Radiohead 

Cadenza 4: Underneath the crisp guitar, you can hear the bass pulsating well. The voice of Thom Yorke are accentuated to a great degree.

EA1000: It sounds great too, but the bass is stronger. The sound has a somewhat sharper quality.

As Before by Olga Konkova 

The cajôn makes a strong impression in Cadenza 4, but the piano justifiably steals the show. The piano sound is organic and natural, easygoing and unforced, and there are no harsh edges whatsoever; the female vocals are superb as well.

More bass, more reverb, and more room to move about are all features of the EA1000. A little sharper, but still warm and pleasant sounding.

It Could Be Sweet by Portishead 

In the fourth cadenza, the female vocals sound completely natural, with no sibilance whatsoever. The bass is prominent and powerful without becoming obnoxious.

The bass is fuller on the EA1000, but it’s less defined. Once again, the tonality is sharper and the sense of space is larger.

Brahms’ Symphony No. 2 III by Paavo Järvi 

The fourth cadenza features powerful bass and haptic kettledrums. The portrayal of the wind instruments and strings is just stunning. There is a lot of room between the instruments, but they still sound full and substantial because to the superb separation.

Even though it’s a little sharper, the EA1000 sounds fantastic.

Young Vivaldi’s Violin Concerto RV 813 III by Ensemble Modo Antiquo

In the fourth cadenza, the strings sound fantastic. While they are aggressive and biting, they also seem organic and rounded. While they aren’t rude, they also aren’t chill.

Quite similar, but with a little more pep in the highs and a sharper treble, the EA1000 sounds a little more active.

Summer 3 – Vivaldi Recomposed by Max Richter

Cadenza 4: A beautifully organized and polished performance. With great imagery and an abundance of detail, everything is in harmony.

EA1000: It’s both more diffuse and clearer, somehow. It sounds much more congested than with the Cadenza 4, and I believe resonance is to blame for the EA1000’s poor handling of the lower midrange.

Limit to Your Love by James Blake

The fourth cadenza has crisp and clear vocals from Blake. There is a lot of subbass and the bass is conveyed superbly. Additional bass is unnecessary for me.

The EA1000 is more bass-heavy, yet it’s a model of impeccable behavior. Both the spatial perception and the tonal clarity have been enhanced. Cadenza 4 features more prominent voices.

EAR TIPS

I compared the Cadenza 4 to my favorite, the wide-bore Azla SednaEarFit Crystal, because, as I indicated before, it is prone to tip-rolling. On the other hand, the SpinFit CP145—my usual general go-to tip—also works wonderfully.

Compared to the Crystal tips, CP145 on the Cadenza 4 produces far more bass. Although the bass is amplified and the overall sound is altered, the distinctions I outlined between the EA1000 and the Cadenza 4 remain largely unchanged after conducting a quick second round of testing with the CP145s.

While I do find the CP145 on the EA1000 to be marginally superior to the Crystal tips, I should note that the EA1000 is not particularly sensitive to tip-rolling and the improvement is just marginal.

WRAPPING IT UP

Sound signature

The tuning of your EA1000 can be influenced by the three included nozzles, as previously indicated. Based on my experience, the golden brass nozzles are the best “middle ground” option among the three ah options.

From what I can see, the tuning of Cadenza 4 and EA1000 is quite similar, however there are a few key distinctions: In terms of bass presence, the EA1000 never fails to impress. Although the Cadenza often has more middle weight, the EA1000 can be more articulate at times; this, however, is track-dependent. With the EA1000, the highs are a little bit more vibrant and defined.

Treble

The treble of both is pleasant and sounds organic. Both of these have a lot of detail. But there’s a distinction. The Cadenza 4 lacks sharpness and has a softer texture. It lacks the EA1000’s audaciousness and articulation. While the EA1000 isn’t overly bright or harsh most of the time, it can get a little hot, the Cadenza 4 stays on the safe side and never gets sibilant.

Midrange

The midrange is where they really shine, drawing your ear to the delectable vocals, guitars, strings, keyboard, etc. There is a lot more midrange volume on the Cadenza 4. Yet again, I get the impression that Cadenza 4 is being overly cautious.

Bass

The bass is more quantitatively distinct from the middle and top frequencies. The bass response of the EA1000 is more robust. While both provide a solid foundation, Cadenza 4 is much more subdued in my opinion. A little extra pep is in the EA1000.

Even with the CP145 tips, the Cadenza 4 still sounds less bass-heavy than an EA1000, but the disparity in base amount is less noticeable.

Soundstage and Imaging 

Their soundstages are equally impressive. For whatever reason, the EA1000 tends to sound a little more airy.

Both have excellent imaging capabilities, while the Cadenza 4 often outshines the EA1000.

Detail, Dynamics and Timbre

They are almost identical in terms of the overall degree of detail. At other times, it seems like one of them is a little more detailed.

On the other hand, Cadenza 4 seems to be more reliable. When listening to the EA1000 alone, I don’t notice any resonance problems, but when compared side by side, they stand out. Thus, Cadenza is more hygienic. When it’s working properly, though, the EA1000 sounds even clearer and more expressive.

Both are extremely lively, but the EA1000 is, in my opinion, more so in most situations. At other times, though, it sounds less crisp and more fuzzy than Cadenza 4, and vice versa.

Though they sound very similar to one another, the Cadenza 4 has a fuller, more controlled sound.

CONCLUSION 

Both the Simgot EA1000 and the Letshuoer Cadenza 4 are excellent in-ear monitors for the money, and they sound very similar. Personally, I can’t decide. Their performances differ from track to track, but I consistently think they are top-notch in every way.

Even though the EA1000 often sounds even more open and lively, the polarity is reversed on occasion. The Cadenza 4 flows smoothly and competently through any situation. The EA1000’s performance is less consistent. While great for the most part, there are instances when the sound becomes too crowded and chaotic, particularly in the lower midrange and mid-bass regions. Additionally, the treble can become somewhat hot. On its own, this doesn’t really annoy me, but when compared side by side, it becomes glaringly obvious.

In sum, both of these IEMs are excellent substitutes. Personally, I can’t decide between the two. The Cadenza 4 is taking it easy without sacrificing quality, but the EA1000 has a spicier sound with clearer treble and richer bass.
