EarAcoustic VSA-V1 — 11.4mm Full-Amplitude Titanium Diaphragm IEM with Tesla Dual Magnetic Circuit

Key Features:

  • Titanium Diaphragm: 11.4mm vacuum-sputtered titanium driver with ultra-fast 0.02μs transient response.
  • Tesla-Grade Magnetics: Dual N52 neodymium magnetic circuit generating 1.6T flux for high sensitivity and speed.
  • CNC Zinc Alloy Housing: Polished shell combining dark aesthetics and acoustic precision.
  • Dual-Chamber Resonance Control: Acoustic wool damping + alloy overtone diffusion guide for expanded soundstage.
  • Sonic Tuning for Female Vocals: Developed from 3,000+ vocal recordings for peak midrange expressiveness and treble air.
  • Ultra-Wide Frequency Response: Covers 5Hz–40kHz, reproducing elusive harmonics with surgical clarity.
  • Premium Cable: 408-core Litz OCC + silver-plated coaxial hybrid, with interchangeable 4.4mm & 3.5mm plugs.

Acoustic Philosophy:

The VSA-V1 is an IEM built to dissect the most elusive sonic characteristics of female vocals. With its Tesla-powered titanium diaphragm and dual resonance cavities, it captures emotion with clinical detail and extraordinary realism. From the breath before a note to the shimmer after a phrase, nothing escapes its blade.

High-frequency extension beyond 25kHz enhances spatial realism, while precision-tuned mids deliver emotional compression and resolution. This is not a warm tuning—it is a vivid, exposed one. You hear the truth of every track.

Ideal for those who seek reference-grade clarity, surgical speed, and a distinctly addictive female vocal profile.
