QUAD ERA-1 Planar Magnetic Headphones

ERA-1 are the first-ever headphones made by Quad.

The brand has been responsible for many landmark hi-fi products throughout its history, none more famous than successive generations of the ESL – the world’s most revered electrostatic panel loudspeaker, a technology invented by Quad’s founder, Peter Walker.

Most headphones use mass-produced dynamic cone drivers, the limitations of which can hamper transient response and cause an uneven frequency response. By contrast, Quad uses cutting-edge planar magnetic technology in the ERA-1, which delivers a more natural and accurate sound, ensuring you hear every nuance of a recorded musical performance.

To create the unique ERA-1 headphones, Quad developed a planar magnetic driver delivering fast, open and transparent performance. The resulting sonic realism and fidelity to the source are fully in-keeping with the brand heritage, displaying qualities akin to their famous ESL loudspeakers.

The Quad ERA-1 incorporates an ultra-thin, electrically active diaphragm – thinner than a human hair yet extremely strong and highly elastic, weighing less than the volume of air it displaces. This is fused with a precisely arranged magnet system, designed to maximise sensitivity and consistency of the applied force over the driver area.

Patented nonlinear vibration suppression technology allows the driver’s effortlessly extended frequency response to be heard unsullied, ensuring supreme clarity. The metal cavity behind the driver is specially designed for optimal acoustic performance, and the drivers themselves are closely matched to ensure spacious, three-dimensional stereo imaging.
