Yes, this is my first time writing a review (and I may make mistakes — that's normal), and I'm starting with an earphone that gives me delightful sensations while listening. It's a planar built in a quite different way from the usual, the Letshuoer Astralis — the brand's newest release, priced at $189 — with a warm, very musical character, smooth, relaxed, and even somewhat technical. It's the kind of IEM you can listen to for hours without getting tired, so succulent is the Astralis.
Disclaimer
This unit was a wonderful gift from a giveaway Letshuoer ran on their social media, and I'm grateful to have been chosen to test the Astralis in exchange for my honest impressions.
Accessories, Comfort, and Build
The box is a standard size for the brand's lineup, but nicely styled and attractive, referencing the name "Astralis" (from the stars). The accessory kit itself felt uninspired for the asking price, featuring the same rigid case found on most of Letshuoer's cheaper models. You get two very basic types of ear tips that do the job well enough. The cable is excellent — it doesn't tangle, is very pliable, has no memory, and is modular (3.5mm / 4.4mm), which is useful for pairing with a variety of sources since this earphone is very easy to drive. It shines with a better source, but the DT01 Pro dongle gets the job done when needed.
The Astralis is made from an aluminum alloy, very well constructed, and the star motifs on the shell give it an elegant look. It's quite comfortable in the ear, especially with the HE Sonic Galaxy tips, which fit the Astralis like a glove, providing decent isolation and allowing you to wear them for many hours without fatigue.
Sound
Sound Signature
In conceiving the Astralis, Letshuoer took an interesting path, combining characteristics of the S08 with some aspects of the S12 Ultra to arrive at a neutral-warm sound with a tuning that shifts between U-shape and even L-shape, along with a mild recession in the mids.
Bass
This is where the Astralis truly shines, especially in the sub-bass, with an imposing and delightful presence. The mid-bass keeps pace with the subs, offering texture, impact, physicality, and definition that are exceptional even by planar standards, staying close to the boundary with the mids without crossing over. Percussion and bass lines make their full weight felt in this region — this is the star of the Astralis.
Midrange
Given the tuning direction, it's natural that the mids are more recessed here, but that doesn't mean they're bad — quite the contrary. They have great smoothness, naturalness, and refinement, with a very gentle pinna gain and incredible softness. The upper mids are more relaxed, which is good for those sensitive in that region; the aggressiveness here is about as fierce as a Pinscher chasing the mailman. With vocals, the highlight goes to male voices, particularly baritones and basses, thanks to the Astralis's warm, textured tendencies.
Treble
Compared to the solid S08, there's a clear improvement in this region — even if it remains well-tempered — and it's still delightful to my taste, with very good control, definition, extension, and speed, plus a subtle and natural sparkle with a relaxed airiness. Detail retrieval here is excellent and expansive, yet with zero sibilance, no odd peaks or coloration, and instruments come through beautifully.
Technicalities
Soundstage and Separation
The soundstage is quite wide, with impressive depth and spatiality, and zero congestion. Instrument separation is a pleasure, making it easy to pinpoint positions, with a rich and satisfying imaging performance.
Final Thoughts
The Astralis is a box of surprises — warm, smooth, relaxed, with an excellent soundstage in a planar that is very different from what we're used to, yet highly entertaining and a formidable option under $200.
