EarAcoustic VSA-MAX 11.4mm Titanium Diaphragm Tesla IEM

Key Features:

  • Targeted Female Vocal Tuning: Based on over 3,000 analyzed vocal recordings for ultra-precise reproduction of Asian female vocals.
  • Dark Aesthetic Shell: Aerospace-grade aluminum-magnesium alloy CNC body inspired by "Dark Night Hunting" motif.
  • Titanium Diaphragm: Magnetron sputtered, full-amplitude design with 0.02µs transient response.
  • Tesla Magnetic Circuit: Dual N52 neodymium toroids delivering 1.6T flux and ultra-low 0.002% distortion.
  • Dual-Chamber Acoustic Tuning: Dampened front chamber for bass control; spiral rear chamber for high-frequency diffusion.
  • Custom Hybrid Cable: 408-core OFC + silver-plated coaxial cable with 0.78mm 2-pin connectors and interchangeable 4.4mm + 3.5mm plugs.

Engineering & Sound Profile:

The VSA-MAX is a sonic weapon forged for vocal purity and emotion. Its titanium diaphragm, with industry-leading rigidity and responsiveness, captures every shimmer and breath. The dual Tesla magnetic engine ensures ultra-fast, distortion-free dynamics.

The unique frequency response dips in the bass for vocal clarity, elevates the midrange for emotional weight, and gently lifts upper treble for airy presence—crafting a vocal-forward experience unlike any other.

Two independent acoustic chambers provide surgical control: the front absorbs excess bass, while the spiral-shaped rear diffuses high frequencies, expanding the stage and layering overtones.
