Acoustic Metamaterial Tuning System (AMTS)

All headphones are subject to high-frequency standing waves which can make the treble sound harsh, fatiguing, or synthetic. AMTS is a patent-pending inline device placed between the transducer and the ear. It integrates waveguides, diffusion control, quarter-wave, and Helmholtz resonators into one compact structure. Diffusion reduces some standing wave formation while resonators act as both precision and broad filters to smooth and shape the frequency response, smoothing the sound from the midrange through the highest frequencies. AMTS renders high frequencies with a refreshingly smooth, accurate, and detailed delivery across all genres. OK, bad recordings are still bad, we’re not magicians!

Stealth’s all-new 4th generation planar

Stealth’s all-new 4th generation planar-magnetic driver delivers the smoothest, richest, and most detailed experience we could create. It’s 20% larger than the E2 driver and uses our patented v-Planar technology to reduce THD and improve low-frequency extension. But we didn’t stop there! Diaphragms are made on an all-new system for a more uniform and consistent tension, lower distortion, and better matching.

Stealth Redefines “Detail”

Stealth’s planar driver delivers incredibly low distortion throughout the listening range with levels of detail heretofore found primarily in the top-of-the-line electrostatics. Unlike many headphones where “detail” is created through exaggerated high-frequency energy, Stealth’s AMTS delivers resolution free from the fatiguing emphasis on the top register users may be used to. Stealth’s 4th-generation driver and AMTS deliver an amazing balance of delicacy, nuance, and slam that will have you reaching for all your favourite recordings, and maybe staying up a bit too late.

And then there’s the soundstage; Stealth is all-enveloping and can compete with even the finest open headphones in depth, width, and imaging. It’s that effortless sense of space and instrument placement that lets Stealth “disappear” so you can simply relax into your musical experience. Everything, the headphones, the equipment, and yes, your daily stresses, just fall away.

If It’s Not Comfortable, Game Over

If a headphone is not comfortable enough to wear for extended listening the design is flawed. Stealth’s ergonomic and stylish ear cups are a natural extension of Aeon 2 ergonomics with a more comfy fit and softer ear pads. Stealth weighs in at just 415g making it one of the lightest super-premium headphones on the market.

Throw in Stealth’s new vegan suede and “leather” ear pads, and self-adjusting suspension, and Stealth is so comfy you can just ignore it and “vanish into your music.”

Finally, for storage or travel, we incorporated our elegant folding gimbal into Stealth, folding it into a compact case that’s small and easy to stow.
