LETSHUOER S12 Ultra Bought them 3 weeks ago and use them every day in the office and at home. Really good quality of sound, clear voice, and bass. Also, want to say about materials, the headphones feel solid and are very valuable. Artem Teslenko 05/26/2026

Shipping Protection by Route Upgraded from S12 I only have the S15’s for a couple of days but I can say that the S15 sounds different, warmer perhaps than the S12. More organic maybe, where the S12 is more ‘rough’ . For both IEM’s I use a Fiio KA17 dac/amp. The packaging of the S15 is excelent! But I miss foam tips. The built quality seems fine although I can’t really judge that after a fee days. But in all I am very pleased with these IEM’s. Peter Koornneef 05/25/2026

LETSHUOER S15 14.8mm Planar Driver IEM Hifi In Ear Monitor Earphone Amazing value Amazingh value, for the price... But also for higher priced IEMs. They're on a more relaxed side. Wich doesn't mean "boring", no, which mean longer listening sessions, confort. Great soundstage, not overly-piercing-agressive details, just details. Rich sound. Warm and pretty cozy sound. Enough of the meta agressive tuning. Astralis want you to take pleasure in listening to your music.
This is my first planar IEMs, I always was mefiant of the harsch side of planar. Not here.
I take those over ISN EST80, Soundrhyme DT900E, Ruviest Nyx... Which are way more expensive.
Little shells, they disappear. I have "normal" size ears.
I tried them with different kinds of music. Extreme music (grind/death/black...), electro, dark ambient, rock, accoustic. Great stuff!!!
Remember that sound is subjective. But this a wondeful surprise. Delirium InSect 05/25/2026

Shipping Protection by Route Great Value IEM I am very picky with my IEMs, I strongly prefer single driver configurations. After a lot of research I landed on the S12, for the single, large planar magnetic drivers. The price is incredibly fair for its category. These sound 90% as good as the 7Hz timeless II’s for 60% of the price.
They have a surprisingly wide soundstage and great imaging for IEMs, thanks to the large planar drivers. They perform amazingly when listening to live music, you can really pick out each instrument and their placement in the recording. They do this with the natural, coherent sound of a single driver design. This trait also allows for excellent performance in movies and video games for a very immersive experience.
The sound profile is mostly neutral, but slightly bright. The mids are full and smooth, though a touch recessed. The treble is bright and airy, without becoming harsh. The bass has great extension and reaches far into the sub bass range. The bass isn’t overly punchy or aggressive, but maintains a solid presence and plenty of definition. These are not bass head IEMs, they’re balanced with a light “V” tuning. These do not get fatiguing over long sessions, but still sound fun and sparkly.
If I have one complaint, it’s fitment. While these have 3 sizes and 3 styles of tips for great tip fitment, the case is large. To fit a huge 14.8mm driver, these cases are big. They are shaped well to fit in an ear cavity, but I find they still push against my ear in some places. I have relatively large ears and deep canals, to get the tips inserted deep enough, they push against the cartilage. This gets uncomfortable during a long session. This may not impact you, but it’s something to consider.
Overall, these earbuds rock! The sound, the tuning, the materials and the storage case. Everything is premium and thoughtful. In its class (single driver planars), these can’t be beat for the money. I absolutely recommend these! Matt cross 05/13/2026

Shipping Protection by Route Clean, Detailed, and Worth It I’ve been using the LETSHUOER S12 Ultra for about two weeks now and I really like it. The sound is clean and detailed, with tight bass, clear vocals, and nice airy highs. It’s especially good for picking out details in music.
Build quality feels solid and it’s comfortable for long listening sessions. Only small thing is it leans a bit bright, so not for those who prefer heavy bass.

[H3] Five-axis machining process
LETSHUOER S12 PRO’s aluminum chassis is shaped to have a snug fit in the concha. The finishing is smooth to the touch thanks to the five-axis CNC machining process. It’s strong, touch and without sharp edges. The chassis comes in a minimalistic profile, with not a lot of wiggle room within the acoustic chamber to minimize reverberation. Dual-pin receptacle is a separate piece protruded from the faceplate so that the irregular shape would not cause distortion.
[IMG: LETSHUOER S12 PRO- Magnetic planar earphones Hi-Fi planar in ear monitors-M4]
[H3] Balanced chassis design
LETSHUOER S12 PRO’s chassis design is a continuation of the predecessor. Multiple vent holes on both sides are effective in alleviating negative pressure build up within the ear canal, and thus protecting the hearing. The independent rear acoustic chamber design makes channel matching to be more consistent. In terms of sound performance, the structural design of the front and rear acoustic chamber effectively discharges the pressure inside the chassis, thereby attaining a more natural sound.

[H3] Ergonomic design details
The earphone connector protrudes slightly from the side of the IEM so the earhook on the cable can sit comfortably on the ear without twisting inwards. The receptor is slightly indented into the chassis to ensure product longevity as well.

[H3] Architectural Reimagination · Acoustic Breakthrough

Astralis features LETSHUOER’s 5th generation proprietary Ring Type planar diaphragm driver. This unit represents a comprehensive restructuring and optimization of traditional planar architecture.By replacing the conventional square driver with a circular one, the design achieved optimal acoustic properties. This breakthrough delivers deeper low-frequency extension and rapid transient response, resulting in an immersive and richly layered listening experience.

[H3] Low Impedance Transmission · Built to Last

LETSHUOER employs a direct solder design for the voice coil circuitry on this planar driver. This structure effectively minimizes impedance, ensuring direct and highly efficient signal transmission. The process makes the driver less prone to oxidation, which not only enhances acoustic performance but also significantly extends the component's lifespan. From structural engineering to craftsmanship, this design elevates the fundamental capabilities of the sound.

[H3] Lunar Silver Grey Aluminum Housing
Astralis features a CNC-machined aluminum housing that provides a rigid foundation for acoustic stability. Ergonomically optimized to contour the ear, it ensures a lightweight and secure fit. The faceplate is accented with a blue star which symbolizes the focused energy of the annular planar driver.

[H3] 216-Strand High-Purity SPC Cable
The Astralis comes standard with a 216-strand high-purity SPC cable, precision-engineered to ensure signal purity and stability. The supple, soft-to-touch sleeve offers a delicate tactile feel while providing exceptional durability. From the core conductor to the outer insulation, every detail is meticulously optimized for acoustic transparency, allowing signal to flow with absolute clarity.
[H3] 3.5mm & 4.4mm Interchangeable Plugs
The Astralis comes standard with 3.5mm and 4.4mm interchangeable plugs. Combined with its 0.78mm 2-pin structure, it offers broad compatibility across a wide range of source devices. From the plugs to the pins, every element is crafted with rigorous precision to ensure efficient, clean, and stable signal transmission.
