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 so 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. These possess limitations 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.

The Quad ERA-1 incorporates an ultra-thin, electrically active diaphragm. This is thinner than a human hair, yet extremely strong and highly elastic. In fact, it weighs 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.

As a company, Quad has never indulged in technical one-upmanship. All their technology exists for a purpose, one that has remained constant over the years: To reproduce music in a form that is the closest approach to the original.

The history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with their first amplifier, which applied fifteen years of knowledge and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of its age.

Every product in the Quad portfolio of amplifiers, headphones, moving-coil loudspeakers and electrostatic loudspeakers have received international acclaim. However, Quad has never indulged in technical one-upmanship. Their technology exists for a purpose that has remained constant over the years - to reproduce music in a form that is the closest approach to the original.

Unilet Sound & Vision are one of the longest-established official Quad dealers in the UK, and one of only a handful of dealers for Quad Electrostatics in the entire country.
