Dan Clark Audio Stealth Planar Magnetic Headphones

Vanish into the music: reference-grade detail, closed‑back convenience

Stealth turns a private listening space into a world-class control room. Its patent‑pending acoustic metamaterial system and 4th‑generation planar drivers deliver a refined, low‑fatigue presentation with sub‑bass authority, holographic imaging, and vanishingly low distortion—without giving up the isolation, portability, and comfort you need for long sessions. Designed and hand‑built in San Diego, Stealth is the closed‑back that invites you to forget the gear and fall into the performance.

Why Audiophiles Choose This Product

• Primary Benefit: Neutral, ultra‑clean sound with deep, linear sub‑bass, smooth treble, and superb front‑to‑back imaging—widely praised for clarity, balance, and low listening fatigue.
• Technical Benefit: AMTS (Acoustic Metamaterial Tuning System) sits between driver and ear to tame high‑frequency resonances and smooth the response; drivers are matched to ±0.25 dB with THD <0.03% (20 Hz–20 kHz).
• Practical Benefit: 415 g with an auto‑adjusting strap, soft vegan suede/protein‑leather pads, and folding gimbals for a compact travel case—built for extended comfort and real portability.
• Compatibility Benefit: Wired, low‑impedance design (23 Ω) with low sensitivity (~86–87 dB/mW) works best with a capable headphone output or dedicated amp from your DAC/streamer, laptop rig, or studio interface.
• Unique Benefit: Among closed‑backs, Stealth is recognized for open‑back‑like spatial precision and composure, credited to its AMTS and 4th‑gen planar driver platform. Community and pro measurements highlight extremely low distortion and excellent isolation for a closed design.
