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.
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.
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.

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.

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.
These are gorgeous headphones—the build quality, materials, and finish are flawless. I’m very impressed; they really give off that premium vibe. I’m also amazed at how you managed to fit a 15.5mm planar driver into such a compact housing—my MP145 are tearing my ears apart 😸. They fit comfortably and ergonomically, which is very important. I’m pleased with the included accessories—your modular cable is luxurious, and thanks for the DAC. Please don’t change the carrying case; it’s the best I’ve ever come across. So, sound-wise, this is definitely a bass-focused planar—I didn’t think you could get this much out of a planar. It’s weighty and energetic; with metal music, I really enjoy the percussion, and overall it sounds great. With electronic music, it’s just wow. But compared to the MP145, it felt like something was missing—specifically, soundstage width and fine details. I suspect you’ve cut the high frequencies quite a bit; I’m not a fan of them, but it feels like something is missing to make this a masterpiece. I also got confused by the positioning of instruments and pinpointing the sound source. It seems to move from left to right, and the sound is a bit vague. In competitive games, I’d have a harder time pinpointing opponents’ locations compared to the MP145. If you fix these shortcomings, this will become a true work of art. You’re heading in the right direction; I like the warm emphasis on the bass. So thank you for these high-quality headphones—they’re now my favorites. All the best to you, and I wish you success with your sales.
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.
Firdt pair of IEMS ive owned and let me say the upgrade is WORTH IT! Having such a good time listening to my favorite songs for the first time all over again. Definitely worth the money!
Finally made the switch to IEM's with a local FLAC libary and music just finally feels alive. Wireless earbuds sound so muffled and mushy compared to these IEM's. You get your money's worth, if not more.
