Nostalgia Listening...
Letshuoer Astralis is amazing colored set —it is the best IEM for metal music (especially early 2000s metal and dark alternative rock) for that price, it is colored in a way that will teleport you back to teenage years, such nostalgic expecrience. It brings a beautifully dark, highly emotional, and rich signature with stellar planar technicalities.

The Letshuoer Astralis is basically the difference between a Realistic Drawing vs. a Stylized Art Piece. A realistic drawing focuses on strict proportions, realistic lighting, and prioritize accuracy—it can feel a bit emotionless. The Astralis, on the other hand, is a heavily stylized drawing: the proportions might be tweaked, but it is immensely expressive, deeply emotional, and packed with artistic character. It transports you straight back to your teenage years listening to Evanescence, Deftones, and Soundgarden.
The Astralis typically retails around the $190.
Accessories, Build, and Comfort
The unboxing package is fantastic. The included cable is extremely soft, pliable, has swappable modular terminations, and zero memory-wire annoyance. The carrying case is solid (though a bit of a fingerprint magnet), and it even includes a dedicated USB-C DAC dongle in the box alongside a solid set of eartips. The physical shells fit comfortably in the ear for long listening sessions.
Sound Performance
The Astralis is a dark-tuned set, but unlike dynamic drivers that get muddy or dull when tuned dark, its planar magnetic driver keeps everything lightning-fast, ultra-detailed, and snappy.
Bass
The bass presentation features a boosted sub-bass with an incredible, deep rumble and long, satisfying decay. Because it uses a planar driver, the mid-bass punch is remarkably fast, snappy, and tactile. It hits hard with zero bleed into the lower midrange.
Mids
The lower midrange is rich, thick, and packed with planar texture, making rhythm guitars and male vocals sound rich and authoritative. Unlike many dark sets that completely bury female vocals, the Astralis places female vocals forward enough to remain clear, emotive, and expressive against the thick low end.
Treble
The treble is detailed and fast with zero planar timbre glare. Crucially, Letshuoer doesnt have the 8kHz peak that is usually associated with planar IEMs. The treble isn't harmonic-forward or sharp—it's laid-back in quantity, but all the micro-details are fully present.
Soundstage & Technicalities
Despite being a dark-tuned set, the soundstage is surprisingly wide, deep, and holographic. Its raw technical capability, snappiness, and micro-detail retrieval keep the overall sound energetic rather than sleepy.
Test Tracks
1. Sibilance / Harshness Test
- Zero Sibilance Across the Board: Tested across Fallujah – "Venom Upon the Blade", Baby Metal, and Knocked Loose. Because the treble harmonics are smooth and laid-back without that 8kHz planar peak, harshness, fatigue, and vocal sibilance are completely non-existent.
2. What it Does Well
- Dark All-Rounder Performance: It acts as a "dark all-rounder." It handles standard playlists (Paramore, Hayley Williams, Tame Impala) with a dark, rich twist over top, keeping the presentation smooth and lush.
- Modern Metalcore / Frantic Metal (Baby Metal, Knocked Loose, Polaris): Riffs and fast kick drums sound insanely fast and textured. While modern metalcore fans who want hyper-bright, forward guitar harmonics might prefer a more open set (like the Binary Acoustics 1900), the Astralis still delivers an A+ performance here.
3. What it Does Exceptionally Well
- Hip-Hop & Synth Wave: Deep, subterranean sub-bass rumble combined with fast planar decay makes hip-hop and synth-heavy tracks deeply satisfying.
- Early 2000s Metal, Grunge, & Dark Alt-Rock (Evanescence, Deftones, Soundgarden, Audioslave, Three Days Grace, Breaking Benjamin): Unbeatable. The dark tuning matches the original recording and mixing style of late 90s/early 2000s rock perfectly. Listening to Evanescence's The Open Door album on this set is a transcendent experience.
- Dark Modern Metal (HEALTH, Vildhjarta): Heavy, low-tuned guitars and atmospheric dark electronic elements sound massive, heavy, and completely immersive.
Direct Comparisons
- vs. Xenns Mangird Tea Pro: The Tea Pro ($300ish) is a classic warm set with more forward treble harmonics, a grainier top-end, and a softer, slightly "poofy" mid-bass. The Astralis completely outclasses the Tea Pro in midbass snappiness and impact, sub-bass depth, and overall emotional engagement for rock and metal.
- vs. Binary Acoustics Chopin / 1900: The 1900 is more vocal-forward, open, and emphasizes treble harmonics much more—making it an S-tier choice specifically for modern metalcore. However, the 1900 suffers from soft, weak mid-bass. The Astralis offers drastically superior mid-bass impact, deeper sub-bass rumble, and a much richer tone for classic rock and metal.
- vs. Erand Resonance 5 / AFUL Performer 7: The Resonance 5 ($200) is like sparkling water—it's more neutral, open, and serves as a balanced baseline for all genres. The Astralis is far more emotional, dark, stylized, and textured in the lower mids. If you want safe neutrality, get the ER5; if you want raw soul and weight for metal, get the Astralis.
Rating
- Bright vs. Warm: One of the warmest, darkest sets in its price bracket.
- U-Shape vs. V-Shape: Highly stylized V/U curve with a rich low-end and smooth, non-fatiguing treble.
- Musical vs. Analytical: Heavily musical and emotional. It has top-tier planar technicalities, but you'll get lost in the rich tuning long before you start analyzing technical specs.
- Soundstage (Narrow vs. Wide): Remarkably wide and holographic for a dark signature.
- Casual vs. Advanced: Beginner-friendly and immediately satisfying—you put it in, play your favorite rock album, and instantly get hooked.
- All-Rounder vs. Niche: A "dark all-rounder." It handles all genres well, but excels specifically as a specialized masterclass for rock, metal, and hip-hop.
- Value: S-tier value at $200. With an included DAC dongle, modular cable, and unbeatable performance for rock and metal, it punches far above its price tag.
Final Thoughts
If you listen to metal, grunge, or dark alternative rock, the Letshuoer Astralis is an absolute must-own. It traded dry, flat neutrality for pure soul, rich lower-mids, and thunderous planar bass. It is easily my favorite set to put on when I just want to sit back, hit play on 2000s rock/metal, and indulge in the music.
