Pickup currently not available
AlNiCo — The Golden Age of Audio in a headphone today. ULI features ETA Audio's 8th generation driver, featuring the exotic magnetic alloy AlNiCo for our smoothest and most transparent sound.
What is AlNiCo?
AlNiCo is an exotic magnetic alloy comprised of Aluminum, Nickel, Cobalt and Iron. You won't find it anywhere other than from ultra-expensive boutique loudspeaker manufacturers or legendary vintage speakers from JBL, Altec, Tannoy, and others. AlNiCo offers unique electromechanical parameters compared to conventional neodymium. This imbues a sweeter decay, lower distortion, and increased efficiency. After years of research and engineering we are happy to introduce this unique and beloved technology to a headphone of the 21st century.
What is ULI?
ULI is our Ultra Low Impedance headphone. Low Impedance isn't just for electrical impedance, but acoustic impedance too. Our design criteria includes a smooth laminar wavefront with no acoustic filters or turbulent resonators, just good vibrations.

AlNiCo is an exotic magnetic alloy of Aluminum, Nickel, Cobalt, and Iron. Compared to conventional neodymium, it imbues a sweeter decay, lower distortion, and increased efficiency — the magnetic heart of every ULI driver.
The ULI's long-gap, short-coil design — rare even in high-end loudspeakers — stays fully within the AlNiCo magnetic field, delivering superior transient response and linearity.
Since the original Genesis driver, we've reimagined every parameter of our flagship — blending vintage AlNiCo magnets with modern materials like our unique silver-copper alloy voice coil.
