LETSHUOER is without doubt one of the main names within the Chi-Fi IEM scene, they usually have constructed a lineup that covers each worth bracket with out feeling random.
Premium releases like Mystic 8 and Cadenza 12 2024 are two of their standout releases of their respective worth ranges, and I often find yourself getting curious the second they trace at one thing new.
I first heard about Ember whereas chatting with Marcus, proper after he demoed a prototype on the nineteenth Shenzhen Worldwide Audio Present in 2025. Again then, even the motive force configuration was unclear, and that thriller actually made it extra thrilling.
I had been ready for the official reveal since then, however the closing product nonetheless caught me off guard. Ember is a premium planar magnetic IEM, restricted to 999 items, which isn’t what I used to be anticipating in any respect.
LETSHUOER has all the time had a factor for planar. The S12 and S15 are already proof that they understand how to try this formulation proper, however Ember is clearly taking part in in a unique league. And with a premium launch like this, expectations mechanically undergo the roof.
On this assessment, I’ll put Ember up towards the SIMGOT EM10, the Softears RSV-MKII, and the THIEAUDIO Oracle MKIII to see if it could maintain its floor the place it actually issues.
Options
It usually looks like planar drivers are usually not evolving all that a lot. Ember makes use of a brand-new 14.8mm massive planar driver.
This isn’t the identical driver platform used within the S12 collection or the S15. It’s a newer unit developed for a extra premium degree of efficiency.
The principle concept here’s a fuller, extra authoritative low finish, one thing many planars don’t fairly get proper. That can also be the place Ember’s tuning steps away from most mid-fi planar units. The sound evaluation will inform if Ember tries to push issues in a unique path.
Ember has an impedance of 30Ω and a sensitivity of 103 dB/Vrms. It wants somewhat further juice to point out its full potential, however it could nonetheless be pushed positive by commonest sources. We’ll discuss extra about it within the “synergy” part on the subsequent web page of this assessment.
Design
This one is all in regards to the small-shell flex. The shells have a compact, slim footprint that sits within the ear prefer it’s meant to vanish. The physique is available in a matte-black titanium alloy end, whereas the faceplate is aluminum alloy, and the distinction works.
It reads “premium” the second you decide it up. The curves are clean, and there are not any sharp corners on the shells. It shares design similarities with the Mystic 8, however the measurement is trimmed down.
The faceplate is the visible hook. It has a flame-like flowing sample. It’s not a loud design. The flames are barely raised, giving the design some depth. They’re painted silver, which provides a shiny define.
The shiny end of the shells can also be somewhat annoying. It seems to be polished and premium, nevertheless it loves fingerprints, so it’s going to decide up smudges and mud over time. You might have to have a fabric round in case you’re choosy.
The nozzle is on the smaller aspect, with a positive grill mesh on high. Tip pairing is simple, nothing bizarre or fussy. The cable connection is an ordinary 2-pin. Total, Ember’s construct feels strong and assured. This construct is unquestionably an improve over their premium planar S15.
Consolation & Isolation
Consolation is without doubt one of the sturdy factors right here, principally as a result of the shells are genuinely small. For many ear shapes, I don’t see the match being a battle. They slide in simply and sit flush, and that tiny footprint helps loads with stability.
For my bigger ear canals, the one actual “factor” is tip sizing. Because the nozzle and the shell are on the smaller aspect, I find yourself utilizing bigger ear tricks to get a correct seal.
In my case, the IEM is held extra by the ideas than the shell anchoring itself, so getting the suitable tip turns into obligatory reasonably than elective.
As soon as I discovered a cosy match, I used to be set. After that, it doesn’t really feel like it’s slowly slipping out or asking for fixed micro-adjustments. I can simply put on it and neglect about it, which is actually what I need from a every day driver.
The shell form helps, too. It’s clean and rounded, with no sharp edges or corners. Which means no strain factors digging into the ear, even after an extended session. The burden is on the lighter aspect as nicely, so it by no means feels just like the IEM is “hanging” off the ear canal.
Isolation is respectable. It blocks chunk of outdoor noise, not whole silence, however sufficient to really feel centered. Additionally, throughout my time with Amber, I didn’t discover any strain buildup or driver flex, which is all the time a aid.
Ear Ideas
You get 9 units of ear ideas in whole. They’re break up into three completely different tip kinds, and every type is available in small, medium, and enormous. So, you might be coated on sizing, and the choice additionally spans completely different bores, from extensive to medium to slim.
The one barely annoying half is that the whole lot is black to darkish gray, so there is no such thing as a fast coloration cue to inform which is which. You’ll find yourself inspecting the bore and stem to determine it out.
In my ears, solely one of many three units actually labored the way in which I needed. This set has a shorter stem and a wider bore, and it simply feels extra “open” and pure.
The opposite two units, with their narrower bores, sound a bit extra closed-in to me. They nonetheless seal positive, however the presentation doesn’t breathe as a lot, and I discover that instantly.
I additionally rolled a number of aftermarket ideas, and the Divinus Velvet ended up being the most effective match. The extensive bore helps open issues up, and the match is safer for my ear form.
I usually want bigger ideas with smaller shells like this, as a result of the tip is doing a lot of the anchoring. With the Velvets in an even bigger measurement, the shells sit in place correctly, and I don’t have to maintain nudging them again in.
Inventory Cable
LETSHUOER tapped Impact Audio for the inventory cable on the Ember. On paper, it reads “premium,” and the collab angle with Impact Audio makes you anticipate one thing somewhat extra. The core is UP-OCC monocrystalline copper, 26 AWG, four-core.
The cable is available in a matte gray sheath, which seems to be very clear and low-profile. It pairs nicely with the tiny shells as a result of nothing about it feels cumbersome.
Even the {hardware} performs it protected. The plug housing is compact and blacked out, with a small brand hit. Some shiny parts match the faceplate and total design scheme.
The included cable strap is a pleasant little element, although. It’s leather-based with LETSHUOER branding stamped into it. For such a slim cable, I’d hardly use this strap, however it may be useful when you’ve got another heavy cables.
However build-wise, I’m nonetheless not absolutely bought. The cable is skinny, and it doesn’t have that rugged, dense really feel you often affiliate with a premium bundle. The braiding is a bit uneven and inconsistent. There are some unfastened twists in case you put these to make use of for a number of days.
This inventory cable is healthier than the Mystic 8’s inventory cable, which felt even slimmer, however I nonetheless suppose LETSHUOER might have simply dropped in one thing with extra presence, particularly with Impact Audio concerned. Additionally, the cable is just not modular, which has been the norm with a lot of the Chi-Fi releases.
I’d have beloved to see an inclusion just like one of many Signature Sequence cables. On the similar time, I get why they went lean. With shells so small, a thick cable would feel and appear form of overkill.
Packaging & Equipment
The unboxing feels very acquainted when you’ve got seen LETSHUOER’s higher-end stuff earlier than. Mystic 8 got here to thoughts immediately, because the structure is kind of comparable. It is available in a big field that appears prefer it needs to make a primary impression earlier than you even contact the IEMs.
On the outer sleeve, you get daring “EMBER” paintings in a silver-and-black theme, virtually like a poster print, with the identify sitting loud within the center. It seems to be dramatic and barely aggressive.
Slide that off, and the internal field switches gears. It’s extra minimal, much less flashy. The highest has that delicate LETSHUOER branding and a clear structure, and then you definately get this dual-door flap design within the center, sealed with the model’s brand badge. It feels good to open, even whether it is easy.
When you open it up, the structure is simple and tidy. The IEMs sit on the highest left in a foam cutout. Proper beneath them is the carry case, spherical and clear, sitting cosy in its personal slot.
On the aspect, you’ve gotten the accent packet and the ear ideas tray, stacked neatly so nothing is floating round.
Just a few equipment, equivalent to a cleansing fabric, a cleansing device, and many others., are usually not current, so it isn’t like you might be unpacking ten layers of stuff.
The included equipment themselves really feel full sufficient, however I nonetheless suppose the field is greater than it must be. The field is half air with numerous foam and numerous house doing nothing. It might have been packed in a extra compact, tighter approach with out shedding that premium really feel.
Carry Case
The Ember comes with the identical carry case because the Mystic 8. It’s that spherical puck case. Shiny aluminum physique and a thick black silicone lid that sits on high like a cap.
I really prefer it. It feels correctly made, and it could take a beating. It’s mild, simple to make use of, and it doesn’t lose its shine.
I’ve been utilizing the one I received with the Mystic 8 for greater than eight months now, and it nonetheless seems to be fairly contemporary. The matte end makes positive the scratches are hidden. No apparent put on, no peeling, and no sad-looking scratches throughout. Inside, there’s sufficient room too.
Ember’s shells are tiny, and the inventory cable is lean, so the whole lot matches with out you having to combat it. The silicone lid closes tightly. Like, you’ll be able to really feel it seal. That provides a little bit of confidence once you’re throwing it in a backpack.
The highest has the emblem, and there’s somewhat lip that makes it simple to drag off. Not an enormous deal, nevertheless it helps. Additionally, the within of this case has a rubber layer, and the underside too. The one within the base is a pleasant contact as a result of it mitigates the scratches.
