Custom Multi-Layer PZT Ceramic Driver
The multi-layer PZT driver refines high and ultra-high frequencies, adding sparkle and micro-detail to your music. After extensive tuning, mechanical artifacts have been eliminated, resulting in a smooth, natural, and lifelike presentation.

“Blazed Titanium” Tuned Nozzles
The ET142 introduces “blazed titanium” sound tubes, crafted through a high-temperature flame-bluing process. This intricate technique involves heating chemically treated titanium tubes with a flame torch, resulting in unique and unpredictable colors ranging from blue and purple to red and yellow. These colors vary based on heat intensity and duration, making each nozzle visually one of a kind.Importantly, the flame-bluing process is a craft, not limited to blue hues. Variations in color and texture across individual tubes reflect the handmade nature of this art. Each nozzle delivers enhanced harmonics, clarity, and speed, making it a dream for classical and instrumental enthusiasts.

Four Nozzle Tuning
The ET142 offers interchangeable nozzles for personalized sound:

Blazed Titanium Nozzle (Transparent Silicone Ring): Extended treble and airiness for classical and instrumental focus.

Gold-Plated Copper Nozzle (Yellow Silicone Ring): Warm and balanced tuning, perfect for versatile listening.

Stainless Steel Red-Circle Short Tube Nozzle: A refined sound profile with enhanced clarity and precision.

Stainless Steel Black-Circle Short Tube Nozzle: Smooth and dynamic tuning with a balanced response across the frequencies.

Premium Build & Ergonomics
CNC-machined alloy construction ensures durability and elegance. The ergonomic design provides a snug, fatigue-free fit, even during long listening sessions, while its lightweight, over-ear configuration minimizes micro phonics.

Flagship-Grade Cable: LC7
The premium LC7 cable blends high-purity oxygen-free copper and silver-plated wires in a 732-core Litz structure, enhancing resolution and dynamic range. Interchangeable 3.5mm and 4.4mm plugs ensure compatibility across devices for ultimate versatility.

Simgot ET142 Review

Intro

Hello, this review and feature covers the latest Simgot Audio iem which goes by the name “Simgot ET142” ($219). One thing I always look forward to featuring at Mobileaudiophile.com is any Simgot release. The ET142 is actually a hybrid iem consisting of one planar magnetic driver as well as one piezoelectric driver. Without question I am very interested to hear the implementation of those drivers. I should also mention that the ET142 happens to be their first set of planar magnetic “in-ear earphones” crafted and created by Simgot. However, Simgot did release a pair of planar magnetic full-sized over-ear headphones over six years ago which went by the appropriate name of Simgot ET1000. To hear that Simgot of all brands have finally gone the “in-ear” planar route is very intriguing. Again, I couldn’t have been more interested to hear this set. No doubt that with the expertise on hand within the roster at Simgot they should have zero issues getting the most out of this set.

Simgot

Friends, I feel like a broken record in these reviews. I say that because out of all the Simgot reviews that I’ve conducted, not one has been something that I turned away. You know, I only review what I enjoy as I value my time and want to spend that time with things that I enjoy. Coincidentally, I’ve featured every one of Simgot’s products that I’ve been sent. Basically, I truly enjoyed their products. I wouldn’t say that I’m a fanboy… but I may be a fanboy. At least a little. At any rate, Simgot has literally taken their whole operation three-to-four years ago from a place of relative obscurity and turned their brand into one of the most prolific, cornerstone brands of this generation within the audio world. I really don’t feel that I’m exaggerating with that statement either. If it’s a Simgot release, then you know you are getting something which has been mulled over to exhaustion. Hashed and rehashed over and over again until the end product is one that deserves the name “Simgot” attached to it. There are a few other brands which embody this work ethic as well. However, I feel it’s important to voice my trust in Simgot. That trust comes from the extensive time I’ve spent with their products. Hundreds of hours, no joke.

Glowing Reviews!

It all began with the Simgot EA500 (EA500 Review) which came out of the gate like a shooting star, taking over the budget market, redefining what the consumer should expect for their dollar. Honestly, it still easily stands up against most any set under $100. Then there was the Simgot EW200 (EW200 Review). Once again, Simgot took the entire budget market and quite literally turned it on its head. Still an awesome iem. After that I reviewed the Simgot EM6L (EM6L Review) which was a total departure from Simgot’s “house sound” so to speak. Another very well-tuned iem. After that I reviewed the Simgot EA1000 (EA1000 Review). Um, folks, find me a better single DD under $250. I won’t hold my breath. Then I reviewed what I considered the best single DD under $100 in the Simgot EA500LM (EA500LM Review). What a fantastic iem for the cost. Next was the Simgot Dew4x (Dew4x Review) which is a very well-made dongle dac. Very nice. I still use it for parts of every review I complete. Then came one of my favorites under $200 iems PERIOD, the Simgot SuperMix 4 (SM4 Review). Lastly, I had the pleasure of reviewing the tribrid Simgot EW300 (EW300 Review) which is a strong performer under $100. I realize that nobody asked for that rundown of reviews, but I did so to cement the fact that I couldn’t be more impressed by this brand. Pick a link and read and you’ll see mostly glowing words throughout each one.

Without Further Ado…

And here we are. I finally received the ET142, and it is sitting in a burn-in station and will remain there for at least four full days. Whether it needs it or not (I’m sure it does) doesn’t matter. I do it anyway. From my first listen I can hear the Simgot DNA is in full swing. I spent enough time with the ET142 to decide what tuning nozzles I enjoy the most, even played around modding too as Simgot made the awesome decision to add tuning foams as well as tuning nozzles. Right away I can hear the making of a technical BEAST! For a first go at the planar sound I couldn’t be more impressed folks. With all of that said, I think my intro is complete. So, without further ado, I present to you my thoughts on the brand new Simgot ET142…

Packaging / Accessories

Unboxing

The Simgot ET142 arrived at my home in a medium sized square box (6” x 6” x 2”) with a gradient light gray to dark gray colorway and a picture of the ET142 on the sleeve cover. The backside of the box has a blown-out picture of the driver configuration and Internals as well as some specs for the ET142. Actually, it’s a really cool design for a box. I don’t ever really comment on box designs, but the ET142 box is pretty slick. Slip off the sleeve as best you can. It took two hands because it is ridiculously tight. I really mean this, good luck. Anyways, slip off the sleeve and you’ll see a cardboard flap with a metallic silver picture of a planar magnetic driver and underneath written in cursive it says, “Salute to Art and Science”. It checks out, in fact, that checks out for all of Simgot’s iems. Nice, moving on. Open the flap and you’ll see the beautiful ET142 chillin’ in some black foam cutouts. Next to the ET142 is a box which indicates “Storage Box” which obviously means “Carrying Case”. Inside of the case is the cable and modular adapters. Next to that box is another smaller box which contains the tuning nozzles. Now, under the ET142 is yet another longer box which houses the eartips, some reading material, extra nozzle gaskets, and even some tuning foam to help tune your listening even further. At any rate, the unboxing is actually quite good. For a box of its size, Simgot squeezed a lot of nice accessories.

Simgot added in high quality accesories.

Eartips

ET142 Eartips

Simgot added in a bunch of eartips within the packaging and each type of tip is actually quite nice. Now, I didn’t actually use any of those tips as I went with the Dunu S&S eartips as they simply sound the best to me, but the added tips included are still great to have in your collection. In total Simgot provides ten pairs of eartips spread across three types of eartips. You get four pairs (XL, L, M, S) of nice black wide bore silicone eartips. They have a firm flange, rigid stem, shallow fit, nice wide-bores. Next, they added in three pairs (L, M, S) of some shallower type of dark gray and red stem silicone tips. These tips have a slightly less firm flange, a hair flimsier along with a rigid stem. Lastly, Simgot provides three pairs (L, M, S) of white silicone tips with a black stem. These tips are very similar in size, feel, and stature to the KBear 07 eartips. Perhaps a hint flimsier on the flange yet still feels rather firm. The stem is rigid, and the bore is closer to a semi-wide bore. Like I said, each style of tips is very nice and could easily be used with other iems in your collection. Thanks, Simgot, nice additions!


Carrying Case

ET142 Carrying Cae

The carrying case provided is a very nice case. I’d say it’s covered in a faux leather, nice stitching. It’s a light gray open top case with a magnetic flap to shut closed. It’s not the largest case. Probably just enough room to store your ET142 and cable. Possibly a really small dongle dac too. It is 3.5” long, 2.5” deep, and 1.5” tall. So, a good size for its purpose. This is actually the exact same case that is provided with the Simgot EA1000. Really a very nice addition into the packaging. I actually never really use any cases but rather have slightly larger cases which can carry more items. Just a reviewer doing reviewer stuff. Yet at times I will use them, and I have to say, this case is one of the few that I actually care to use. It’s just very nicely made, nice to look at. I do wish it was a hint larger. Maybe large enough for another set of earphones and cable, but I’m not complaining. It’s an elegant case for a very elegant set of iems.


Tuning nozzles

ET142 Tuning Nozzles

Like I said, Simgot added in four different tuning nozzles as well as extra foam inserts all in an attempt to provide the consumer with a way to tune their iems to fit their particular tastes. One thing is for sure, these tuning nozzles do make a difference. Some more than others, but I found that with the help of the tuning nozzles and the foam inserts I was really able to dial this set in. However, I did go with the “short black nozzle w/the black silicone ring” during critical listening. I’ll explain next. Anyways, I love that Simgot actually added nozzles which are productive at making actual changes in what I hear through the ET142. Simgot also added in one alloy carrying block which gives you the ability to put two sets of tuning nozzles screwed onto it. The other nozzles are simply put into a baggie. Anyways, it’s a nice feature of this set and I’m glad that Simgot had the presence of mind to add them.

What do they do?

Golden Copper Nozzle & Yellow Silicone Ring:

This nozzle is tied as the brightest of the nozzles as there is no tuning mesh added, no foam, no-nothing but a mesh earwax catch. This nozzle will give you the exact tuning of this set yet with the slight difference that copper will add to the sonic character of the iem. I find this nozzle too bright for me. Definitely a treble-boi nozzle.

Baked Blue Titanium Nozzle & Transparent Silicone Ring:

This nozzle is just as bright as the golden Copper nozzle, yet the sonic character is a hair different as the material used is titanium. Again, too bright for me. Highs are pretty intense. That said, this is the nozzle that I used the tuning foams with where I was able to really dial in the sound. It’s open inside which is nice for fiddling around and modding the nozzle to fit what I like. However, I won’t speak on that because this is a review over stock sound.

Stainless Steel Short Nozzle & Red Silicone Ring:

This nozzle is the warmest of all of the nozzles. In fact, both of the “short” nozzles veer towards warm. It is amazing that I can go from bright to warm simply by using tuning nozzles. Really a large swing in sound. With this nozzle, the real change comes from the upper midrange through to the upper treble. Not an insane difference but you’d be surprised what some treble reduction will do for your listening experience. Bass is deeper, more of a focus too, less intensity, less shout. I definitely enjoy this one.

Stainless Steel Short Nozzle & Black Silicone Ring:

Now this is definitely the nozzle that I enjoy the most. Well, this week anyways. So, the black ring short nozzle is almost identical to the red ring nozzle yet with a touch more upper mid through lower treble emphasis. It’s a very small difference, maybe 2-3 db’s. However, that “little bit” makes a world of difference. It gives me just enough bass focus, treble emphasis, presence up top, and the sound retains mostly all of the technical abilities while coming across more balanced as a whole. Definitely it fits me the most besides my modded nozzle.

Tuning Options

Simgot ET142 Review Pic (102).jpgPlease remember that Simgot added in the tuning foam in the packaging and so you can really drop the sheer amount of treble and upper mid activity. In all truth, my favorite way to hear this set is with the titanium blue hue longer nozzle with some tuning foam inside. Again, for critical listening the short stainless steel nozzle with the black ring is just about the same for me. Perhaps a hair more upper mid energy. However, what Simgot did with this set is give us plenty of options. It comes down to how much you enjoy treble and brilliant energy. You can most assuredly dial that down quite a bit. The amazing skill of this iem is what makes it so nice as no amount of foam inside of the nozzles created any kind of veil and the driver control remains. It’s just a very nice set. I tossed around the idea of reviewing this set with my modded nozzle but after burn-in and hours of brain burn I began to truly enjoy the short stainless nozzle with the black ring. At times the red ring nozzle fits my fancy too, but I had to make a choice. Still, it’s a wonderful thing to have choices and flexibility. Simgot has the forethought to provide us with those options. Friends, that is part of what makes this brand so special.

Cable

Simgot LC7

This is one of my favorite pieces to the ET142 puzzle. Simgot added into the package one of my favorite cables under $100. That is the Simgot LC7 modular cable. The LC7 itself costs upwards of $70 and so it is a very viable cable to use with the ET142. The LC7 is a beautiful metallic white, coaxial Litz twist, 2-pin cable with perfectly contrasting mirror polished silver copper alloy fittings (Y-split, termination housing etc.). The look is so perfectly made for the ET142! I love good aesthetics, and I laud brands who actually think of this part of the package. You need a good looking cable with your earphones. Okay, “need” is a little over the top, but you know what I mean. The look is perfect for the ET142. The mirror silver of the fittings next to the mirror polished design of the ET142 and the metallic white twisted cable is absolutely striking. Now, the LC7 is made with 732 cores (fatty) of high-purity oxygen-free copper and silver-plated wires. Simgot also adds an anti-oxidation pvc coating which supposedly has anti-aging properties. Pretty cool. To add to all of that, the cable is MODULAR! Thank you Simgot! Thank you! How nice is it to simply pull off the termination and put in the one you need? I know, I have many modular cables too, but that doesn’t make it any less nice. The LC7 comes with both a 3.5 single ended termination and a 4.4 balanced termination. I am very happy with this cable. Such a nice inclusion!


The ET142's cable is amazing
One of the best cables you can buy under $100, in my opinion is the Simgot LC7.


Build / Design / Internals / Fit

Build Quality

The actual build of the Simgot ET142 is made by way of CNC machined alloy (likely stainless steel) which are fairly large in stature and are literally smooth everywhere. The ergonomics are perfect for my ears. The ET142 housing has one small vent towards the nozzle. Also, the nozzles (all nozzles) are exactly 6mm in width. Folks, this set is built very durable with such a premium feel to them. I would say that the ET142 are a heavier set of earphones. I don’t know exactly how heavy they are but they’re pretty stout, substantial, and could easily be used as an awesome paperweight. Of course, that would be the ultimate shame because the ET142 looks and sounds so much better when in the ear. Also, I found that the weight distribution is such that I don’t even notice the weight at all. Really a wonderful build for a +$200 set of earphones.

Simgot ET142 Build Quality
The ET142’s build quality is through-the-roof, very well designed and structurally of great quality


Design

Now we get to the design of the ET142. Actually, did you like the design of the Simgot EA500? Well, if you did, you are in luck because the design of the EA500 is pretty much the exact design of the ET142. You have the gorgeous high-polished mirror alloy covering the entirety of the ET142. Simgot also very elegantly added in their logo with a very slight gray color placed in the center of the faceplate area. Such a tasteful and graceful look. Only those who truly understand elegance and minimalist design can craft such a look. It is astoundingly nice to look at. I give Simgot two thumbs up, A+, five stars, and whatever other indicator that I can to denote something which is the embodiment of the panache sophistication. I know, I realize that I may be going a bit strong on this description, but I mean every word. Truly, a wonderful job Simgot!

Internals

As I said earlier, the Simgot ET142 is a dual-driver hybrid earphone. Simgot used a 12.5 mm planar magnetic driver (PL) with an ultra-thin diaphragm encased in a dual-sided magnetic system. This driver covers most of the frequency from the sub-bass through to the highs. The other driver is a piezoelectric driver (PZT) which covers the whole of the treble region or possibly the high-highs. I don’t know exactly where the PZT comes into play. I want to note something as well. The ET142 is strikingly similar to the Raptgo Hook-X in the fact that the Hook-X also used a PL/PZT arrangement, and their frequency graphs are extremely similar. Just thought I’d throw that out there as the Hook-X is clearly one of the best planar sets on the market under $300. I can tell that the drivers used in the ET142 are superior, but it’s worth noting. Anyways, I love the choice of drivers with this set. Other than the drivers and driver materials I don’t know much more about the internals or the acoustic cavity etc.

Fit / Comfort

As I said, the Simgot ET142 is very ergonomic for my ears. I realize this is a very subjective thing to say as it only applies to me, but I’d think the ET142 would fit most hobbyists fairly well. I find them to be very comfortable in my ears and over long listening sessions. To add to that, some of my sessions can regularly go hours on end. No fatigue at all. Maybe I have to take them out to itch my ear from time to time, but they really are very comfortable for me. I have zero idea how this set will fit you, obviously. But again, I cannot imagine that they wouldn’t fit nicely for most people.


Simgot ET142 Review Pic (56).jpg


The Simgot ET142 works well with many sources

Drivability

Sensitivity / Output-Power

The Simgot ET142 is rated with an impedance of 14 ohms and a sensitivity of around 118 db/vrms(@1kHz). Basically, the ET142 is not a super hard set to drive for volume. Even cheap dongle dacs can get this set to volume. However, I hardly feel that using a weaker source is the best way to go with this set. In my listening I quickly found out that the ET142 most certainly scales with good and clean power. Of course, I also figured this would be the case being that this set is a predominantly planar earphone. So, I could use the ET142 with weaker sources and it doesn’t sound bad at all, but I wasn’t getting the most out of it. This is always a difficult section to write about because what we hear is so subjective. You may love the way the ET142 sounds off of a cheap Amazon dongle dac or the Apple dongle. For me, I notice a definite tightening up of the entire frequency when going from one of those lesser powerful 3.5 dongles or my older Android smartphone to the EPZ TP50 on high gain, for example. Really any of my solid dongle dacs was usually plenty. However, without question I received the best sound quality when I paired the ET142 with my much more powerful and more talented daps & dac amps. Like the Hiby R4, iBasso DX240, Shanling M6 Ultra, or even the Fiio Q15. Tighter bass, less splashy upper treble, less planar timbre, and simply more of a dynamic range.

Source tonality

Simgot ET142 Review Pic (63).jpgHow the ET142 responds to your source tonality will depend at least slightly on what tuning nozzle that you prefer. This is another highly subjective topic. I know we reviewers like to speak in absolutes and declare which source tonality is best for whatever set we are reviewing. However, the truth is that it will come down to you and what you enjoy. I can tell you that for me I enjoy a warmer/neutral to neutral source. That said, I don’t enjoy (as much) sources which lean bright or analytical. I much more enjoy a more musical sounding source too with the ET142. Without question my favorite pairing is with my Shanling M6 Ultra. However, even more neutral devices sound nice with this set as well. Dac/amps like the Fiio Q15 have that clean, neutral, and dynamic sound which pair nicely with the ET142. I can tell you this, you certainly don’t need more brightness or treble emphasis, I would think anyways. I suppose if you’re a treble junkie than you’d probably invite more treble sheen. At any rate, most sources do quite well with this set. It may go without saying but the ET142 will certainly reward you for pairing it with more talented source devices. Better dac chips, better amps, circuitry, and for lack of a better words… simply more sonically gifted devices.

My favorite, the Fiio Q15 and the Simgot ET142
The Fiio Q15 is certainly a very gifted dac/amp and the ET142 sounds great with it.


Sound Impressions


*Note: Before I delve into the sound, I should first inform you all that I did give the Simgot ET142 about four full days of burn-in. Without question burn-in should be conducted with the ET142. Also, I listen mainly to flac or better files stored on my devices with a little streaming here and there. Also, I listen mostly using the UAPP (USB Audio Player Pro) Android music player along with Hiby Music Player from time to time. I also used Dunu S&S eartips for all critical listening. Lastly, I used the “stainless steel short nozzle & black silicone ring” for almost all critical listening and so my findings will mostly be using that nozzle.

What’s it sound like?

The Simgot ET142 comes across as a very clean and cohesive sounding planar hybrid. No doubt about it that this is a planar type of sound, full of fast twitch muscle reflex and about as dexterous as a set can get. Very agile as the ET142 maneuvers through dynamic shifts, hard stops, attack and recovery in an energetic yet very well controlled manner. This is a somewhat vibrant iem, even with the short stainless black ring nozzle. It’s boisterous, vivid & transparent with nice cadence and a very kinetic charge to the sound. In the same breath, I wouldn’t call the sound strident or too brightly colored (depending on your nozzle choice). Words which first come to mind concerning the sound of the ET142 are vibrant, controlled, structured, impactful, untarnished, and vigorous. In no particular order. Highly complicated tracks seem to not be a problem. This set will have your mind’s eye concentrating on details you didn’t know were there. A very prolific technical iem which doesn’t leave out some semblance of musicality. A lot depends on the track obviously, but Simgot did a very nice job for a planar/PZT hybrid iem costing under $250.

Sound signature

Simgot ET142 Review Pic (35).jpgI’d probably call it a W-shaped sound signature though I could see someone calling it a U-shaped or even a slight V-shaped sound as well. I only say W-shaped because of the fact that the midrange is fairly far forward, pronounced and simply situated closer to the listener. Depending on the nozzle that you choose, the ET142 can go from sharp, bright and snappy to smoother, slightly warmer and snappy, but always snappy. I happen to enjoy smooth and snappy (stainless short nozzle & black ring) and so that’s what I’m going to speak on. Anyways, what you have is a real bite to most all notes depending on the track. If there’s a hard edge, it’ll sound as though there’s a hard bite. There’s a lot of crispness, nice crunch, sharp attack, clean attack, quick decay, and unsullied note outlines. Just a very clean sound. Note weight is not thin, but not thick either, and I still hear adequate density to each note. A certain dynamism with more voluminous macro-dynamics and a nice contrast in tones. However, the ET142 doesn’t lack musicality either. Again, there’s a warmth to the sound with this nozzle and I can’t stress that enough. Some of the other nozzles are a much brighter and more exaggerated W-shaped sound with even more bright energy. That said, it isn’t all cold, dry, and bright. It definitely does lean in the direction of analytical, yet it also carries some tunefulness and a certain symphonic quality which keeps the ET142 from leaning entirely towards the clinical side.

Sound cont…

The ET142 has a big and rigid sub-bass along with a sprightly and brilliant treble that really makes percussion “pop”. Also, the driver control is really great. You don’t have those lingering harmonics mashing together the edges of notes with other notes. Clean separation and excellent clarity. With all that said, the ET142 won’t come across as the most organic sounding iem as far as timbre is concerned. It definitely has its moments and there definitely are tracks which sound more organic than others. Certainly, it isn’t artificial sounding. Only the very slightest planar timbre using the brighter nozzles. I would say right away that the ET142 is not going to be for those folks who desire a warm, laid-back, and lush sound with earthy timbre. However, the ET142 is a very skilled iem and I’m quite positive that most folks will realize this very quickly. Basically, those who really want to try out a planar iem which is always on point, precise, yet doesn’t leave out all emotion will enjoy what Simgot has created.

*Note: The graph below indicates the stock tuning. Remember that each tuning nozzle will present the frequency a hair differently. My preferred nozzle has less upper-mid emphasis for instance. Just something to consider.

Simgot-ET142-Review-Pic-87.jpg



Bass Region


The low-end of the ET142 is mostly showcased within the sub-levels with a healthy dose of emphasis which does its best to offset the energy up top. With my nozzle of choice, it is a nice balancing act which makes for a very nice listen. Now, the bass is one of impeccable control with a tight, acutely impactful and very pointed attack edge that decays very quickly. As many planar magnetic earphones do. We should expect as much. No, you don’t quite get that atmospheric and textured decay of a dynamic driver, nor do you get quite the depth. But I promise, the ET142 doesn’t miss by much, at all! Also, who’s to say that a DD bass is the best way to hear bass? Many folks desire planar style bass more. I am not one of those people, but I can really appreciate what Simgot did here. Also, planar drivers can do things that DD’s really cannot easily replicate. However, the ET142 really does hit hard when called upon. Way more than enough to satisfy. It’s rich, full-bodied, and it can bang!

Bass cont…

Furthermore, this is a low-end which can go from 0-100 in the blink of an eye yet with solid bass density. The speed is one of its really nice attributes. I have yet to hear a track that the ET142 couldn’t keep up with. I tried too. The nice mix of speed and density is one of the better qualities of the ET142 in my opinion. All things considered, the ET142 from Simgot has some very nice low-end muscle, some chasmic and low-droning rumble, and some very nice and clean impact. The bass has great note definition and is so far from being one-noted that I thought I heard the ET142 start to belly laugh in my ears for even thinking about it. Fast, tight, profuse in its emphasis, plenty of weight, and not in the slightest form is this bass weak. Basically, the ET142’s bass region is quality over quantity with plenty of quantity.

Sub-Bass

Looking at the sub-bass I’d say it’s pretty clear that the Simgot ET142 can flat-out BANG! Notwithstanding, that “BANG” doesn’t seem to ever muddy the low-end waters. No over-emphasis, always fantastic note control and clean note contour. It’s the type and style of sub-level rumble which drones deeply yet in a very structured manner. I hear nothing even remotely sloppy. Fast, clean, highly resolute, bullish in its tapered and arrow-like attack with a prompt transient decay. No it isn’t some lingering, atmospheric, resonant filled or ear massaging style. It doesn’t detonate sending long drawn out aftershock reverbs to every corner of your brain. If you’ve heard a planar style bass that isn’t so one sided towards the lows, then you know… they hit n’ git. If I’m being totally honest, and I am, the bass on this set can be very enthralling and the sub-bass is a huge reason for that. Listening to The Wilder Blue in their track “Feelin’ the Miles” you’ll hear a fairly bulbous and meaty bassline with a full toned bass guitar that you can feel. It’s the extension down low which gets me. It’s the shuddering and juddering pin-point and hard edged crest of every note which makes me hit replay just to hear it again. Basically, the ET142’s ability to dig deep with a nice haptic feel to my music is great, while at the same time never muddying the mix is a treat for this guy.

Mid-Bass

Like I said, the sub-levels of the mix carries the majority of the convexity of the bass shelf. Just like every region on this set, it’s fast and tight, taut and defined, and it has a penchant for never missing a beat. Now, the mid-bass isn’t the most robust area of the mix, and it doesn’t steal focus. I would call it moderate in overall emphasis and authority. That said, I really don’t miss anything, and I actually really enjoy this slightly lifted mid bass region. I can tell you this for sure; the ET142’s mid-bass isn’t even close to muddy. If anything, it’s the exact antithesis of the word “muddy”. Clean-lined, streamlined, and very tidy. Certainly not what anyone would consider basshead. However, the mid-bass is also bolstered by the sub-bass quite often. What you get in this area is just enough fullness for Kick-drums, bass guitar, baritones, etc. Tracks like “2040” by Lil Durk and Lil Baby produces a fairly strong boom on the bass drop. Anyone listening to that track wants that bulbous bass to bullishly bang. I wouldn’t say that bassheads would be impressed, but those who enjoy a quality mid-bass with a solid technical footing should appreciate what the ET142 can do. It’s skilled folks… nuff’ said. Well, there’s actually quite a bit more to say. Like, when I’m listening to the track “Billie Jean” from Weezer. Right out the gate you hear some fast repetitious kick drums. One after the other. I enjoy that the ET142 keeps such a pristine note edge, nice timbre and doesn’t feel like it’s lacking either. Granted, it isn’t slam-city, but I get that nice snap on attack quickly followed by a nice and cavernous boom. Nice enough anyways. Really, it all comes down to how you like to hear your music for a track such as this.

Mid-bass cont…

There are obviously many sets which can produce more emphasis at this price which will provide a much more dense and textured low-end note delivery. Not to say the ET142 is without texture or density, because it certainly has enough of both. Though it simply won’t be able to be fully appreciated unless you actually desire a set with less robust fullness and more clinical quality. Having said that, as a whole the ET142 is very close in quantity to a set like the Raptgo Hook-X for example. It hits pretty hard. If you know that set, then you know that you won’t be missing any low-end rumble. Or something like the 7hz Timeless. Actually, to my ears the ET142 has more low-end weight than the set which started the whole planar craziness. Now, the ET142 does have some brightness to offset the boom. However, for the 20th time I have to say that you get to change up the sound to fit your fancy. I am so very satisfied with the mid-bass slam using the short stainless black ring nozzles as there’s enough thrumming meat and shuddering slam for most any track. That all said, no doubt about it that the ET142 has a highly skilled bass in this region and will truly take on any track. I should also add that the midrange does receive a bit of bass bleed. Just enough to add some warmth.

Downsides to the Bass Region

I’d say the number one thing which the ET142 is guilty of is that it isn’t a dynamic driver. Be that as it may, the ET142 gets you somewhat close. On top of getting you close, it also can-do things that most dynamic drivers cannot do. Still, the ET142 doesn’t quite have the organic and resonant impact of a DD. Again, it’s so close that most of you won’t even notice. This I can assure you. It’s only when you actually listen for it. I say that because the bass on the ET142 is very full bodied, very rich, and it really does hit very hard. However, it’s also very impressive technically which simply leaves that last touch of lingering harmonics and bulbous depth. I also think that bassheads, or even moderate bassheads won’t be entirely in love. Yes, the ET142 can bang, and yes, the sub-bass rumbles in a very deep and guttural way when called upon, but the ET142 does miss a hair in the mid-bass. Once again, I really miss nothing with this set. I understand what it is and what it’s good at. Perhaps texture is ever-so-slightly not as evident, but that is hardly the most vital piece to this low-end puzzle. In truth, I feel that Simgot nailed this bass. For a planar set it rumbles in a very deep and palpable way. Again, very rich and full bodied. There’s plenty of haptic vibratory goodness, clean and well-defined notes, fast attack through recovery, not even hinting at anything muddy, veiled, or one-noted as well. It’s a solid low-end.



The Shanling M6 Ultra & Simgot ET142 Planar


Midrange

I feel that the midrange is probably the focal point of the ET142 and depending on your nozzle situation it can go from slightly lean to a natural semi-rich note weight. I really don’t consider this set to be thin, dry, anemic or frail, at all. No way. The ET142 has a vibrant presence, very airy, open, well-separated, it’s fast too, with details coming out of the woodwork to get to your ears. This would usually make me think that the mids are analytical through and through. Well, they partially lean that way, but the midrange also has a certain smoothness which is very nice to the ear. Think of a sound which is ridiculously fast, controlled, tight around every corner, no track too fast. Now think of that same set with a smoother note inflection. Not too sharp, mellifluous to an extent as well. The mids definitely have some levity however with very nice transparency. Some tracks can be a hair hot due to the pinna rise but not glaring to the point that it induces pain or makes me want to turn the volume down. I cannot stress enough that you need to try all nozzles. The two longer and brighter nozzles sound extremely similar and those two are pretty bright. I am not talking about those. The only thing I like about those nozzles is that I can mod them to sound more like the two shorter nozzles. Anyways, I digress. The ET142 has a very nice sounding midrange. It’s forward in a pleasant way and the midrange has a very nice note presence with very nice etched note outlines. Nothing grainy or fuzzy.

Mids cont…

Also, the stage is wonderful too. I hear nicely delineated note separation accompanied by solid layering of sounds. Something most planars aren’t usually good at. There’s only a couple that I’ve heard with the depth of field similar to the ET142, and those are the Letshuoer S12 2024 Edition, and the Letshuoer S15. I wouldn’t call the midrange “holographic” per say, but I would say it is well sparse-out with solid imaging and decent front to back layers for a planar magnetic earphone. Also, in my opinion, the midrange is more natural tonally than it isn’t. You don’t have that earthy type of organic or analog style sound, but the midrange also isn’t plagued with planar timbre or metallic timbre. There’s the faintest touch of it that you really cannot get around with a planar tuned this way, but it is not even close to a problem for me. I don’t even notice it actually unless I strategically listen for it. So, the timbre is actually fairly nice. I think what keeps it from perfectly natural is its tight transient behavior. Again, very little lingering harmonics. In the same breath, those tight transients are one of its best qualities. I guess like anything it all comes down to what you enjoy. Thankfully, I enjoy just about every sound signature and so I really do recognize where Simgot got things right.

Lower-Midrange

Looking at the lower-midrange, I hear some decent warmth and body along with some vibrance. Not vibrant as in “bright”, but vibrant as in “energized”. There’s a certain air to the sound which makes the lower midrange come across open sounding and not dull or flat. So many sets suffer from a more obtuse, blunted, or edge-less sound here. Not the ET142. Along with its smooth under-body the ET142 has plenty of surface texture and crispness. It’s a very tangible and tactile sound. More corporeal and vivid too. Basically, the low-mids aren’t boring and have plenty of edge when a track presents it. Now, when I think of the low-mids I usually think of male vocalists. It’s the easiest way for me to explain the sound rather than going through every Instrument. For instance, “Rome” by Dermot Kennedy. His voice is full of that Irish pronunciation, which shows clearly in his songs. His voice has an edge to it, it’s slightly abrasive, especially when he belts stuff out. However, his voice has some authority and weight to it too. The ET142 really does his voice some justice. The edge to his voice isn’t inflated, or magnified. While the edginess is there, it isn’t too coarse or dissonant. Really well highlighted against the melody which surrounds his voice too. More forward than it isn’t, yet not boxy. Really, a nice take on the low-mids. Of course, less edgy voices like Sam Barber in “Cold, Dark Place” sounds very melodic. His voice comes across uplifted, tuneful, and the ET142 shows off great clarity too. I know some people enjoy warmer and lusher sounding low-mids but I cannot knock the ET142 here.

Upper-Midrange

The upper-mids are most certainly more forward than the lower-midrange. As you’d expect. The ear gain rises about 12 db’s using the brighter “long” nozzles. Yet the nozzles that I enjoy are less pronounced and so they don’t come across quite as energized or shouty. You see, right after the pinna rise is a short-lived roll-off and dip which seems to keep the glare at bay. To tell you the truth, females actually come through with awesome presence. Generally, their voices seem to project or extrude toward the listener with a clean note outline and decent note body. Slightly thinner and slightly drier than the low-mids, but still nice. Singers like Norah Jones in “Don’t Know Why” sound so very silky, smooth, and just plain charming. There is not even a hint of bad timbre in this track. Very pleasant to the ear. Her voice is perfectly centered, forward in the sound field while the acoustic guitar and piano sitting a hair further back. Really harmonious. Having said that, her voice sounds good on almost any set.

More of a test

However, Sia‘s track off her new album called “I Forgive You” has a bit more contrast to it which may present more problems for the ET142. Nevertheless, the ET142 replays her scratchy and resounding vocal inflections very well. I like how the ET142 doesn’t fall flat on its face in this track as there’s way more than enough moments for it to do so. As uplifted and airy as this set is, Sia’s vocals never induce any sharpness. Perhaps there is a hint of thinness, but man I am reaching when I say that. Honestly, females sound pretty nice folks. However, I need to test this set with the real glaring tracks, like “The Otherside” by Cam. For whatever reason her voice just hits that right frequency which if played with the wrong set will definitely force your in-ears to no longer be… in your ears. I have so many of these types of tracks in my “Shout” playlist and honestly the ET142 generally keeps everything together nicely.

Instruments

Folks, I really don’t like explaining instruments as every track is not recorded the same, every track is different, and not every track is going to sound the same for every instrument, obviously. That said, the ET142 replays most instruments a hair off of organic. Being a planar definitely has its upsides, and downsides. Yes, it hits those transients with ease and illuminates every detail with good resolve. However, some fundamental and secondary harmonics may sound a hair stripped. As though the notes cut-off seemingly clipping the full breadth of those notes. Having said that, the ET142 does a nice job tonally. Percussion has a hard snap and a thrusted crash. Snares “pap” with very solid energy. Or the fundamental tone of a cymbal strike sounds slightly scaled-up or more slightly more intense. Strings of all kinds. Violin can come across silvery, glassy, lustrous, and even elegant. Woodwind instruments are ever-so-slightly embellished but also leaning toward the natural. I could go on and on folks. Basically, instruments come across pretty nice for the tuning. Maybe a hint more energetic than some may like, and perhaps not perfectly authentic to life, but I don’t hear anything which is downright “off”.

Downsides to the Midrange

To me the biggest downside of the midrange is that those who enjoy a warmer, lusher, and richer sound in this region aren’t going to get that here. So many hobbyists prefer a thicker sound. So many enjoy an easy-going and even smoother sound as well. No doubt the ET142 is an acquired taste. Like anything. However, not everyone is going to be down with its more lustrous sound. It’s just the truth. I can tell you that I’ve spent so many hours with the ET142 in my ears and I have more than grown accustomed to the way it portrays the midrange, and I quite like it. Brain-burn is in full effect. I actually went back to the Aful Explorer after weeks with this set and the sound came across veiled in comparison. Granted I love that set, but I say that to make a point. The ET142 has a sound that will grab you when you least expect it. Also, this midrange has so many upsides. Especially when speaking in its technical capabilities in conjunction with its symphonic sound. Not bad at all.



Simgot-ET142-Review-Pic-90.jpg



Treble Region

The highs in the ET142 are without question the most energetic part of the spectrum. They come across with plenty of solid treble crunch with a sparkly clean-cut resonance. It can go from “pretty brilliant and emphasized”, to “very brilliant and very emphasized” just by modifying the sound using the tuning nozzles and included foam inserts. I would definitely say that using the Golden-Copper nozzle will be a treat for treble heads. As we’ve learned throughout this review I mainly listened with the less intense short stainless nozzle. That said, the ET142 has a very lively macro-dynamic sound with forward instruments in this region that are very well articulated. You have a lot of nice driver control as well. To my ears the piezoelectric driver seems to be well implemented. I don’t get that electric-metallic “zizz” at the crest of each note like I do on so many other sets using a piezo. I can’t imagine it’s a very easy driver to tune. However, when done right, they can sound like they have all the earmarks of a nice treble driver. I give all of the credit to the people over at Simgot as they really did a nice job. Now, I’d say the ET142 certainly has a more analytical approach to this area of the mix

Lively & well contoured

Now, the treble on the ET142 has plenty of upper range emphasis which is contrasted well enough against the lift in the bass region. No doubt this is a brighter iem. Yet that brightness never really becomes fatiguing for me. The treble is very well controlled. Every note seems to have some decent treble bite. I hear a punchy treble with solid enough note body. The treble region is well done with a tactile and even slightly haptic style sound. The track “Evil Twin” by Lindsey Stirling is one which shows off that ability. This track moves along at a fairly fast speed with quite a lot of treble output and the ET142 never seems to cross the line into offense. Each note sounds very clean, satisfyingly edgy, solid note body too. Each leading edge on attack has a tasteful abrasive quality, is well textured, and has plenty of micro-details coming forth. Ultra crisp and very sparkly without killing my ears in the process. Really a nice replay of this track. In my opinion the ET142 has solid note structure and a well laid out note contour in the midst of a very lively and sprightly sound. For me a lot depends on the nozzle I choose to use. For instance, using the brighter gold nozzle was just a tad too much vivacity for my ears. I’m sure treble heads would be right at home, but I much more enjoyed the slightly toned down stainless short nozzle.

Airy, open, extended

Another solid quality of the treble is how open and airy it is. What this does is add what I perceive to be a more uncluttered and spacious sound across the mix. The ET142’s treble most certainly uplifts most frequencies by bringing some exuberance and dynamism to the sound creating space between notes along with ample amounts of sparkle as well. The ET142 also has great extension into the highest of highs. The upper treble region, or the “air” region has more than enough emphasis to give the secondary harmonics of a cymbal strike some real nice presence, for example. Like I said earlier, I don’t hear anything outright splashy, and I don’t hear anything outright artificial sounding either. In fact, timbre stays close to natural for me. Well, maybe “bright/natural”, if that’s a thing. Also, the good extension provides a wider overall sound field. A psycho-acoustic stretching of the stage. Couple that with the deep and extended sub-bass and what you have is a pretty vast showcase by the ET142. Better extension usually will add some width to the sound and the ET142 is a testament to that.

Speedy

To add to that, the ET142 has a keen ability to take on most any track that I throw at it with relative ease. It doesn’t seem to matter how complicated it is. If the track is well recorded the ET142 will resolve every note very well. That piezo and planar combo is really a winner when it comes to speed. However, it isn’t just speedy as it also doesn’t lack quality either. I’ve heard plenty of very fast treble sets which don’t really present notes very well. You’ve heard them, they will sound as though you're swimming in a pool of treble tizz and sheened out treble. Not the ET142. At least not with the nozzle I enjoy. At any rate, the treble is very skilled. A very open sounding, transparent, and clean-lined sound that’s highly resolving leading to solid detail retrieval, nice note separation, and one of the better treble showcases I’ve heard under $250. Also, just like every other area of the mix transients move along very rapidly. Again, I would think that anyone who really enjoys treble will enjoy the ET142.

Downsides to the Treble Region

As much as I enjoy the highs on this set, that certainly doesn’t mean that you will enjoy the highs. Yes, you can change it all up to your hearts’ content with modifications, but without question the treble will be too bright for many people. This hobby is so diverse. In fact, I went through a stage not too long ago where I only wanted rolled-off and dark treble. So, I get it. Nothing is for everyone. At any rate, there are plenty of people who are sensitive to a more treble-focused iem who may want to keep looking. Beyond the emphasis, I really do find the ET142 to be a special set with a very competent and compelling treble region. It adds such a nice vivacious energy and does so without coming across too sharp, harsh, or grating.

Technicalities

Soundstage

The soundstage is great, and I feel it’s certainly a “pro” for this set. Listening to the ET142 I definitely hear above average width of the sound field. In fact, above average is a very conservative thing for me to say concerning the width of this stage. Height is also very nice too. Yet what helps the Simgot ET142 the most in providing a captivating stage would be the depth. Now, I’m not saying “best in class” or anything, but the fact that the ET142 is a planar magnetic earphone and there is any depth is saying a lot. This is not usually the case. In reality many planars come across with a wider presentation. However, that wide stage is also usually a flat plane of sound in front of the listener. Thankfully the Simgot ET142 has enough good depth for solid layering. I won’t go so far as to say the stage is holographic, but there is some dimension to the sound. All things considered, the ET142’s stage size and quality are pretty darn good.

Separation / Imaging

I think you already know exactly what I’m going to say here. But humor you and speak on it again. So, the Simgot ET142 really does have excellent separation of elements within the stage. There is plenty of good space created to provide very well designated and delineated instruments and voices. Unequivocally, the ET142 is a technical beast. The note control is great, the sound is transparent, clean too. The ET142 has a very open sound, very aired-out while also having transient attack through decay which is fleet-footed and swift. It has glass-lined notes, a black background too. These character traits all help in the ET142’s ability to sparse out instrumentation very well. Imaging is just as solid too. I have zero issues placing elements of the stage in particular spots in the sound field. Both separation and imaging are strong “Pros” in my opinion.

Detail Retrieval

Again, I’ve said it a few times, but detail retrieval is fantastic. This set has no issues highlighting the subtleties within my music. Even in complicated passages the ET142 seems to be able to take them all on. Again, for all the reasons that this set separates and images the stage at a top class level are some of the same reasons that it’s able to put a spotlight on the minutiae. Whether it be the subtle breath in a mic, hard to hear noises in your favorite live track, finger slides on the guitar strings, to all the resulting gradient harmonics which would be much harder to hear on a less able iem, the ET142 performs. I’d say the only real stipulation would be that heavy bass dominated music will obviously be harder to spot those subtle details. The bass can mask over certain areas and simply make details harder to detect. I should also add that the ET142 will most certainly play much better in quality recorded tracks. On the flipside of that, the ET142 will definitely let you know if your music is not a quality recording. Also, not everyone wants to be forced to pay attention to all of those details. Sometimes you just want to close your eyes and casually listen.

What a beauty of a planar from Simgot.

Planar Wars! Comparison
Simgot ET142 / Letshuoer S12 2024 Edition

Letshuoer S12 2024 Edition ($199)

S12 2024 Edition

The Letshuoer S12 2024 Edition came out last year with a bang. I reviewed the S12 2024 (S12 2024 Review) at some point last year and I gotta tell you guys, I fell head over heels over that set. Without a doubt it’s one of the best planars within the entire market. For many reasons. Now, the S12 2024 comes with a very large 14.8 planar magnetic driver and one of the best looking iems as well. This is a set which blasted off into the audio-world stratosphere very quickly. Letshuoer took all of their combined knowledge crafting planar sets and put it all into this special addition iem. Really a solid set for the cost too. Let’s see what the differences are.

Differences

To start, both iems are built using all-alloy. Both built extremely well, very durable, very stout. The ET142 is a little bit larger in overall size and it has a deeper fitting nozzle too, so you may want to keep that in mind. I fins the ET142 is a hair easier to get to seal in my ears as well but that’s highly subjective. As far as design goes, the S12 2024 is simply stunning with its golden mirror like colorway. Having said that, I personally feel that the Simgot ET142 is clearly the better designed set of the two. As nice as the S12 2024 is to look at the ET142 is a clear winner in my book. So classy, elegant and clean. Between the two the S12 2024 probably has the more ornate and lavish unboxing (clearly a special addition set) but as far as actual inclusions the ET142 definitely has the better cable. Both sets come with a boatload of eartips and both sets have a nice carrying case too. I’d say that they are equal in this department after all is said and done. Having said all of that, the S12 2024 is a hair cheaper by about $20, give or take.

Sound Differences

I’ll be honest, I don’t know if the S12 2024 was the best comparison to use for this review. Really it sounds very different from the ET142. For one, the S12 2024 is a much warmer sounding iem, less technical, more musical, less crisp and crunch and less bright. Also, the S12 2024 definitely comes across more organic and less intense with a more naturally organic sounding timbre. However, the ET142 is much more refined in its technical approach and the driver combo of the planar & PZT do seem to add some better layering, better separation of instruments, better imaging capabilities and a wider stage. Depth is about equal too but the ET142 has the better layering as well. The ET142 is definitely the more open sounding set, airier, better stage size.

Each 3rd of the mix

Starting with the bass region the S12 2024 has the more forward bass. It also has less treble output which certainly helps to give a more pronounced bass section with more slam and boom by the tiniest margin. That said, the ET142 has the more defined bass with a more guttural sub-level bass. Again, by the slightest of margins. The midrange if the S12 2024 has the more authentic timbre in my opinion while the ET142 is a titch less natural. I suppose a lot has to do with the boosted treble and upper-mids. Of course, change your nozzle situation and you can get the ET142 sounding pretty nice and closer to natural. Once again, the ET142 has better detail retrieval within the mids and a more open and separated sound. The ET142 is more transparent, cleaner, more crisp, and more vibrant too. Also, the treble region on the ET142 has more brilliance, better extension, and it carries a better quality treble in my opinion as well. I should also note that the S12 2024 does very nicely in the technical stuff too. Basically, it’s no slouch. However, the ET142 is on another level in this regard. Folks, both of these sets have their own rewards and both do very well for their respective prices. Really these are two totally different sets as far as their sound signatures.

Final thoughts on this comparison

I’ll be honest, I love both sets for different reasons and different uses. One is slightly musical and very technical, while the other is slightly technical and very musical. Both are top class for planar sets around $200. Both truly have wonderful implementations of planar magnetic drivers. Clearly there are some fairly magnificent experts tuning them both.

The Simgot ET142 & the iBasso DX240

Is it worth the asking price?

The Simgot ET142 comes in with an MSRP of right around $219. That’s a ton of money for many people around the globe. Not everyone can just plop down +$200 on a set of earphones. To add to that, there’s plenty of lesser expensive sets which almost get you to the quality of the ET142. Like the Hidizs MP145 (MP145 Review) which is one of the legendary planar sets. Truly a performer across the board. Also, the Letshuoer S12 Pro. Another very competent planar iem. In all reality, I could name so many sets which are great for lesser prices. This hobby is filled with them. It all comes down to you, your pocketbook, and your sound signature preferences. However, preferences aside, I can tell you with complete confidence that the ET142 is worth every last dollar of that $219 that Simgot is asking. Will it be for everyone? Of course not. Despite that, for those who are seeking out a set with the ET142’s style of tuning I think that this set is a complete no brainer.

The Why…

Because the ET142 is built like an absolute tank. The alloy used is polished to a gorgeous mirror finish with the small Simgot logo very lightly imposed on the center of the faceplates. I can’t get over how nice this set looks. The mirror look is really enthralling. Such a classy, dignified, and handsome iem. Also, the ET142 is outfitted with awesome accessories. The cable is one of my favorites under $100 and you get a bevy of tips and a nice case too. Then you have actual working tuning nozzles which make large somewhat differences in sound are included as well. So the unboxing is pretty great. Yet when it comes down to worth, the only thing that ever matters is the sound. The bass hits so deep, extended, and guttural. I hear such a solid and dense sound yet with a very tight transient response. Next, the midrange is great for vocalists for an analytically leaning iem. I said it earlier in the review and I’ll say it again; the Simgot ET142 is not without musicality. The mids are very precise, unsullied, and speckless. Then comes the treble which is so very capable folks. The crunch, the crispness, the punch, the bite and the brilliance. The ET142 definitely has a very refined sound. Again, detail retrieval is more than adequate. Separation of instruments is stellar, Imaging is spot-on, and I hear actual layering happening within a very nicely sized stage. It all adds up people, the ET142 is without a doubt worth every penny.

Ratings (0-10)

Note: all ratings are based upon my subjective judgment. These ratings are garnered against either similarly priced sets or with similar driver implementations or styles with the unique parameters of my choosing. In the case of the Simgot ET142 ratings below, that would be $100-$250 planar magnetic iems. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an iem what it is. A “5-6” is roughly average and please take into consideration the “lot” of iems these ratings are gathered against. $100-$250 planar iems are not a large sized scope of iems. So, It should more common to see a rating above a “9.0”. My ratings are never the same and each set of ratings tells a different story. Each time you read one of my ratings will be unique to that review. Basically, I create a Rating that makes sense to me.

Ratings Summary:

I feel like the ratings above pretty much say everything and I don’t feel that there’s much to explain either. For this rating period I pitted the ET142 against any planar magnetic earphone between the prices of $100 and $250 that I have heard. I had many of these sets during this ratings comparison and I feel that the ET142 was probably the most skilled of them all. Some were more musical, bigger low-end, better for vocalists, etc. However, the ET142 quite easily deserves the “9.6” that I earned. Now I haven’t heard every set within this price range and so I cannot say I’ve heard them all. Still, I feel I have a good idea where the ET142 stands. The crux is that these ratings will only tell you my opinion, for me. You may think very differently than I do. So I would urge you to take these ratings lightly. They are only one man’s opinion folks. Remember, grains of salt.

Conclusion

To conclude my full written review and feature of the Simgot ET142, I want to first thank the good people of Simgot for providing the ET142 in exchange for a full feature at Mobileaudiophile.com. Simgot thank you! Also, thank you to you, the reader, for taking the time to click the link and check out any review at Mobileaudiophile.com. You have to know that this means quite a lot to us as your clicks really does benefit the website. It’s our best hope that you would take something away from our reviews and possibly help in your journey to find the best audio devices to suit your preferences. So, thank you!

Other Perspectives

Also, I must add that I do feel it is a good idea to check out other thoughts besides mine. Folks, we are all so very different and each one of us has our idea of what either “good” or “bad” sounds like. We all don’t have the same hearing abilities, we may not have similar music libraries and tastes, and not everyone has the same gear either. Also, we all haven’t been down the same journey through audio. That journey does help to shape and form opinions. The point is that we are not all the same and not every reviewer is going to judge the same. So I do hope that you will take a look at other perspectives on the Simgot ET142. I do believe that will help you to make a purchasing decision.

Lastly, I dont want to leave this review without giving the Simgot ET142 my recommendation. Without a doubt this is one very talented iem. Yes, it is an acquired style of tuning and may take a moment. However, I also think that the legendary Simgot EA1000 is also an acquired taste for many. I’m telling you, the ET142 is a flat-out and hands-down PERFORMER! I love that I have options to dial in the sound to my particular sound ideals. I can mod till my hearts content. However, there are so many reasons why this set is worth every penny as well as being one of the better iems that $220 can get you. Just a fantastic addition to the audio world. So, the Simgot ET142 is an easy rec from me. With that, I think that I am done. Again, thanks to Simgot, the wonderful rep that I deal with (you are awesome Betty) and thank you for visiting. Please take good care, stay as safe as you can, and always…God Bless!

Simgot ET142 AKA Prometheus
DSC02487.JPG

The newest IEM from Simgot is not without some minor controversy. Initial batches of the new Planar based hybrid from Simgot got some not so warm impressions from the regulars on the tube with some saying its good but the tuning is a bit hot. Some just outright did not like them. I do know on open listen they are not ideal. My own initial take on the ET142 was not all that complimentary of the IEM but this was one where I had a feeling a bit of time tinkering with its tuning nozzles with a bit of burning in would help. I have heard a lot of IEMs that don’t sound so good out of the box so the ET142 was yet another IEM that I don’t recommend actually taking seriously till you get some hours on the baking oven and I highly suggest trying out their included nozzles before assessing the ET142.

The sound gets smoother, more bodied with better cohesion, the trebles especially changed for the better. In other words, the sound has matured a lot and is not the grainy mess I heard on open listen. As of writing I have had the ET142 for a few months actually and it was due to Simgot pulling a bit of a surprise. Simgot looks at reviews and to their credit they have held onto the initial launch of the Prometheus AKA ET142 until they did some extra tinkering in the form of extra nozzles. They now include 2 more nozzles in their box package so you now get a total of 4 sets of nozzles including the two original ones that came with the initial batch of the ET142. With the ET142 getting a nice longer run in and with the new additional nozzles for the ET142 the new name for the ET142 is now Prometheus. Simgot is ready to launch their newest planar hybrid.
DSC02527.JPG

A few disclaimers on the way I assess IEMs. First of all I always burn in every IEM I review at a minimum of a week's time. I do take some notes between open box and their final sound so it has nothing to do with my brain getting used to the IEM. Guys that have a knee jerk reaction to how the new Prometheus sounds out of the box and take the sound for what it is without burn in are doing the IEM a disservice in my opinion. That goes for every IEM. I am a very firm believer of getting the best out of every transducer that goes into my ears to know the sound before reviewing. Take that for what it's worth because there are a lot of reviewers online and on the tubes that don't care to do any of that. Truth is some IEMs reveal themselves right away and some don’t. Prometheus is the latter. These take a bit of time and tinkering to get the best of which I will describe here for my reader.

I use a minimum of 5 different sources. Which in my opinion is the minimum for really getting to know a sound. But that's just me. I see too many reviews of guys using a single source for their review and once again that is doing the IEM injustice, as there are some that believe sources don’t matter. In any case, here are my thoughts about Simgots newest Hybrid the Prometheus.

I would like to thank Fia Lam of Simgot for providing a review sample of the ET142. You can find more information about them here. The ET142 has been burned in for a week period and has been listened to on and off for a period of 2 months. My sources used for the ET142 are the IBasso DX300Max, Ibasso PB5 amp, Ibasso DX180, Fiio M15, Fiio M15S, IFI signature and Fiio K9 pre ESS.
DSC02542.JPG

The old burn in debate might peep its ugly head on the topic but I know for a fact folks that don’t bother with any of that before doing any reviews, hence the not so positive reviews of the ET142. I suppose when you have over a dozen new IEMs on the review cue and no time to burn in anything, I can understand that. On the other hand, some IEMs need that time for the driver to settle and bring out its best version of itself. The ET142 sounded especially harsh on open listen. All that has changed due to Simgot recognizing a few aspects about the ET142 tuning that does not bode so well for western likes in sound tunings.

There are IEMs that don't need burn in but the ET142 is an IEM that absolutely requires it for them to show what they are about. To my surprise a lot of the criticisms I had earlier about the shouty nature and such are mostly gone but it also has to do with the new nozzles they have included. I am hearing much better cohesion between planar and PZT drivers which is yet another reason for burning in the Prometheus. Bass seems to have better clarity and definition. Mids sounds more smoother with an organic overtone, much more melodic, better density with more substantial note weight. It was the upper mids and treble which were the areas of contention on the open box listen. Trebles much better after a week of burning however it still has that Piezo characteristic timbre. The good news there is that It's actually integrated well with the Planar. Way better than on open listen. It has to be one of the best implemented Piezo drivers for its sound I can think of.
DSC02529.JPG

What they come with.

The new Prometheus comes with a gray colored rectangular medium sized box case with a magnetic lid. This case is just big enough to store the Simgot LC7 cable with its 3.5mm single and 4.4mm balanced plugs, A set of extra tips and the IEMs. This is a case where I feel the case does not account for the more substantial LC7 silver plated OFC cable which cost about $60-$70. It all fits in the case but barely. I think Simgot would have done better to provide a bit larger case for the Prometheus. It also comes with 3 sets of silicone tips and 2 new shorter filtered nozzles that clearly changes the tuning of the new Prometheus and if that's not enough, it also comes with a set of their tuning foams meaning you can customize the Prometheus to exactly how you like to hear your new Planar hybrid.

Sigmot tuning.
Simgot does several variances of the harmon tuning. Which some folks are not a fan of, but today's IEMs all seem to use a variant of the harmon tuning to one degree or another. It is now rare to see an IEM not have any pinna gain or an enhanced upper mids emphasis. The way our hearing portrays sound that emphasis is needed for sound balancing and presences for the mid bands. Prometheus is guilty of having a bit of extra in an early 2.5khz pinna gain with its stock nozzle and treble that has a spike at the sensitive 8khz region. If you end up trying their gold nozzle the sound does become a touch shouty and that 8Khz spike in the trebles causes a bit of glare for percussion noticed for crash cymbals for rock music. The mids are actually organic sounding with a smooth finish and its bass end is impressive with a boost towards its sub bass. Planar timbre is a thing for IEMs and while I perceive the Prometheus to have a timbre which is a touch soft it makes up for it with an organic smooth musical tonal quality. I really don't have issues with the timbre characteristics and surprisingly the PZT here does a splendid job with the upper treble notes, especially noted after burn in. The 2 new tuning nozzles are physically shorter and with more dampening material which lowers the areas I spoke about earlier.
The good news here is that with the inclusion of these two new tuning nozzles makes the Prometheus much more versatile. The Prometheus goes from analytical and a bit brighter in tuning to a much more musical and even a slightly warm one. Ya you read right, a warm Simgot? The nozzles don’t seem to hamper any of the technical traits of a highly resolving planar driver being used for the Prometheus.
DSC02531.JPG

The 2 new nozzles introduce a slightly warm one in the red ringed nozzle. The other set which is the same nozzle with different level of filter in it and black rings to differentiate from the other set is somewhere between the stock longer nozzles blue and copper and the new warm red ones. The initial longer nozzles have the most upper mids per Simgots harmon tuning philosophy and I had these nozzles long enough to actually get them to sound a lot like the new shorter ones. As they are, the gold nozzle has roughly 13dbs of pinna gain and to my ears does introduce a bit too much upper mids with the inclusion of that 8Khz emphasis. If the Prometheus was reviewed just using this particular nozzle, it would take a warmest sounding source and your thickest pure copper cable to tame that upper mid brightness.

Fortunately, we got choices. Using the longer blue nozzle things get a bit more interesting while still having what I am guessing to be about 11dbs of upper mids. This is the nozzle that comes preinstalled on the Prometheus. That enhanced 8 khz emphasis for trebles seems to highlight the upper mids even more so which makes the blue nozzle tolerable but not so much for your favorite rock tracks.

I know you're thinking, what would make these a good listenable IEM then? Even before Simgot created these two new shorter nozzles, I did some tinkering of my own. What I did was include the tuning foams from the EA1000 tuning kit. But that's a mod you say? Nope. If the inclusion of the new tuning nozzles are not enough for you. Adding a single foam piece underneath one of the included nozzles will smooth out the enhanced areas of emphasis for you.
DSC02532.JPG

For my ears I like a foam piece underneath the blue fired nozzle. It takes a bit of the edge off the trebles and the upper mids for me. A bit more clarity above the new black ring nozzles, yet similar in balancing. The new red ringed short nozzle brings down the upper mids of the Prometheus to about 7dbs which makes them sound more balanced, the blacked ringed one seems to be about 8-9dbs. Now we are talking.

Simgot has given the end user. Choices, that saying we all hear differently is so true. It all comes down to just how much upper mids and trebles you like. The included nozzles and foam pieces are all as easy as screwing them on and in my case just inserting a piece of foam underneath the blue nozzle. And with each nozzle change I would highly recommend tip rolling to get the best possible sound for your use case.
DSC02535.JPG

Trebles
I have heard plenty of IEMs using PZT or piezo drivers and the Prometheus has a very good integration of the PZT driver for its upper trebles air and detail elements. Its main point of contention is at that 8Khz where it clearly has some emphasis. Again, you can tinker with the foam pieces or the new included nozzles till you get that emphasis tamer than what comes with the copper nozzles. It's interesting that manufacturers seem to think they need to add another driver for upper treble extension and as you know PZT drivers were included to enhance that region. For IEMs that I have reviewed in the past, planar drivers seem to excel at trebles very well actually. I think I would have been more happy if Simgot used a more resolving dynamic driver for bass and just tuned the Planar here for mids and trebles. I know they have used the PZT in their quadbrids the SM4 and tribrid EW300 so maybe they are happy with the results of the PZT driver and carried over that to the Prometheus. In any case. If you're a treble fan you will be happy that the new Prometheus has plenty of treble presence and its extension is ideal. It might have a bit too much actually especially if you're sensitive to the 8Khz emphasized region. The copper nozzle is where it gets a bit much in the treble region in conjunction with the most upper mids for its tunings.
I doubt treble folks will complain about not having enough emphasis here. To be honest I actually like that the treble is not rolled off in the least bit. It's got a full on treble extension and presence for all things trebles. Tinkering with the included nozzles and foam pieces will get the trebles to be just right for you. As you can tell, all this takes a bit of time and my experiences with how I hear them now is in no way a knee jerk reaction to how they sound out of the box. This is one IEM where you have to spend a bit of time on it. In the end It will be worth that time to get them to sound just how you want to hear them.
DSC02533.JPG

Mids.

This is the strength of the Prometheus,
So here is where those tuning nozzles will play a part in how you like your mids tonal qualities. The foundation for some smoother full bodied mids are there. The nicely resolving planar driver does a very capable job with the mids presentation which is more bodied than the mids from the SM4 and is more spacious with a better stage than the EW300. Overall sound with the right source can bring out some really good layering in space. Imaging is a strong suit of the Simgot IEM and the Prometheus delivers with a well separated image. I noticed planar timbre was more evident on open listen for the mids more so than how I hear them now. Overall it has natural tonal quality but can be manipulated with the nozzles. It can sound brighter with a more forward female vocal presentation, also highlighting stringed instruments- copper and blue nozzles. Or with a slight warmth and more body highlighting male vocals with a more balanced mids presence-2 new nozzles red and black ring new shorter nozzles. The large planer driver used while giving a bigger sense of stage is not the most dimensional sounding. I would say dimensionalism is an aspect for sound that is difficult to relay correctly. We use the word holography and dimensional and how that translates to how I hear the Prometheus is that it sounds more single plane in sound or more neutrally present vs imaging that floats in space from much higher end IEMs for example. At the given price point this aspect is certainly not bad but something I have noticed as Bone Conduction drivers are the new bell of the ball nowadays which helps with the dimensional aspects of a sound. I have reviewed other Planar IEMs the Letshoeur S12 pro and Dunu Talos, both of which also has a higher degree of resolve. The new Prometheus not only goes toe to toe with them in how resolving the sound can be but It has much more in the way of versatility in its tuning via nozzles and foam dampeners vs both those sets.

Bass

Bass has a tasteful lift toward the sub bass with about 10 dbs of emphasis, an enthusiastic emphasized amount but not exactly basshead level. Simgot does not make basshead level IEMs, on the other hand I have yet to hear a Simgot made IEM with a weak neutral bass emphasis. Its bass ability is adaptable to all music types and genres but does portray the slightly quicker decay of planars for IEMs. And here is where I kinda miss the bass end of the old EA500 or better yet the EA1000. In comparison, that shorter decay does not bring the most textured bass performance. However, all is not lost, for something like speed metal and rock music with faster bass notes, planar bass is just as speedy as a well-designed BA driver. Advantage of the planar driver happens to be its speed, showing excellent tightness for the bass note. Now when it comes to a textured slower decaying woofer sub bass note, this is the area I feel a well vented dynamic will win just about every time for IEM applications. Prometheus has no issue handling a proper tonal character and emphasis for bass. The problematic area for me is in its texture for sub bass. Somewhat soft sounding but to be fair I am comparing the bass ability vs some of the best dynamic bass characteristics. For what it is, the bass end is very capable and even enjoyable. Its emphasis has enough mid to sub bass for proper pop, jazz, edm, hip hop and rock music but true bass aficionados will be wanting a bit more there especially from the sub bass notes from a quality perspective.

If sub bass especially is your thing for IEM performance. Even though the Simgot EA1000 bass emphasis is actually a bit less in emphasis. Its bass definition and texture are excellent at about the same price range.
DSC02537.JPG

Closing thoughts.
Simgots new Prometheus is one of those IEMs where they will benefit greatly with some time on the burn-in station and nozzle rolling is required, know this when going into a purchase. The good news there is that each of the 4 nozzles bring a different sound profile, and one is bound to suit your own likes in the sound balancing which can be even more fine-tuned with dampening foams which are included in the packaging. If the trebles are a bit spicy for you from using any of the nozzles, again them tuning foams will do wonders for how you like to hear your trebles.
DSC02525.JPG

I know Simgot has a following of enthusiasts that take their releases very seriously. The negative stuff you see and read about this IEM is not as bad as you think, and I don’t care who wrote or shot the video review about them. My advice is try not to take an open box review seriously. Because in my view that person is not actually testing the entirety of what the IEM is about or can do. The ET142 is an IEM that absolutely needs burn-in for better cohesion and fullness of sound. Then you have to tinker with the nozzles to figure out what sound balancing you prefer, then you have to tinker with your best tips after that to finish off that sound. For me it was a piece of dampening foam underneath the stock blue nozzle which ended up sounding good enough for me. The newer shorter nozzles Simgot has included on their newest packaging will actually get you closer to the sound balancing I have achieved, especially the black ringed short nozzle. If you're not one to tinker with nozzle filters you can just use that set. And it is with these newer nozzles that the sound achieves a good price to performance level for the Prometheus. Optimizing the sound of the Prometheus ends up being rewarding with an engaging musical sound, good technical chops with an organic tonal quality and why wouldn’t you want that for your new IEM. Thanks for taking the time to read.
