All headphones are subject to high-frequency standing waves which can make treble sound harsh, fatiguing, or synthetic.

AMTS is a patent pending inline device placed between the transducer and 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.

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 favorite 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 a headphone is not comfortable enough to wear for extended listening the design is flawed.

Stealth's ergonomic and stylish ear cups is 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, self-adjusting suspension, and Stealth is so comfy you can just ignore it and "vanish into your music.”
