Adastracoustic Meta

Dual Active Dynamic Architecture
Meta employs an advanced dual active dynamic configuration—two independent dynamic drivers working in harmony. A 13 mm driver handles the low frequencies, producing deep, powerful bass, while a 10 mm metal-diaphragm driver refines the mid and high ranges with exceptional clarity and speed. This structure ensures tonal density and dynamic precision across the entire spectrum.

LPF-Duct Acoustic Design
The proprietary LPF-Duct system isolates airflow and resonance between the two drivers. Acting as a miniature acoustic tunnel, it minimizes interference and distortion while improving transition smoothness between low and high frequencies. The result is a more natural and coherent sonic balance, with better separation and reduced muddiness.

High Sensitivity and Driveability
With an ultra-low impedance of 2 Ω and a remarkable 139 dB SPL @ 1 mW sensitivity, Meta is effortless to drive even from smartphones or portable DACs. Every component—diaphragm thickness, voice coil wiring, back cavity volume—has been precisely tuned to optimize transient response, maximize dynamic contrast, and extract the full musical potential from both drivers.

Bass: Deep and Controlled
The 13 mm dynamic driver delivers authoritative bass with exceptional control. Sub-bass extension reaches deep while retaining speed and definition, giving percussion and basslines weight without smearing the midrange. Each note feels textured and tactile, with an airy sense of space rarely found in in-ear designs.

Midrange: Clear and Lifelike
The metal-diaphragm driver produces a midrange that is articulate, detailed, and natural. Vocals sit slightly forward—intimate but not congested—while instruments retain body and harmonic richness. The tonal balance feels organic, making Meta a pleasure for both male and female vocals, acoustic instruments, and layered studio productions.

Treble & Soundstage: Open and Expansive
Treble extension is smooth, luminous, and free of harshness. Cymbals shimmer without glare, and microdetails remain clear even at low volumes. The soundstage is remarkably spacious, with precise imaging and three-dimensional depth that evokes the sensation of a small live venue. Genres like jazz, pop, and R&B benefit especially from this immersive presentation.

Acoustics-First Housing
Meta’s housing is built from high-strength metal alloy, designed not just for durability but as part of the acoustic system itself. Every contour, chamber, and port has been modeled through simulation to ensure optimal airflow and resonance control, resulting in an enclosure that reinforces sonic accuracy while maintaining ergonomic comfort.

Precision Manufacturing & Testing
Developed through over 900 days of iterative prototyping, Meta underwent extensive acoustic measurements and subjective listening tests. Each production unit adheres to tight tolerances to ensure consistent sound performance—hallmarks of Adastracoustic’s artisanal manufacturing ethos.

Accessories & Finish
Included are three pairs of silicone eartips, a premium leather carrying case, and a 4.4 mm balanced cable for uncompromised signal transmission. The polished metal surfaces, engraved branding, and gold-plated connectors underscore a luxurious, handcrafted aesthetic that complements its sonic excellence.
