Quad 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.

To create the ERA-1 – the company’s first-ever 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’s heritage, displaying qualities akin to the famous ESLs.
