Quad HIFI Era 1 Headphone

Product information "Quad ERA-1"
"Closest Approach to the Original Sound" - "closest to the original sound" since 1936, these words form the foundation of the QUAD philosophy. It's more than just a slogan, it underscores the company's ambition to produce the best audio equipment that can reproduce all the elements and emotions of a live music performance. Throughout its history, QUAD has been responsible for many groundbreaking products, none more famous than subsequent generations of the ESL - the world's most popular electrostatic flat panel speakers, a technology invented by QUAD founder Peter Walker. QUAD has used its experience with electrostatic speakers to develop its planar film diaphragm headphones - the ERA-1.
To ensure a natural sound in line with the company's tradition, QUAD engineers have developed a planar magnetic propulsion film that provides fast, open and transparent performance similar to the famous ESLs. Most headphones use mass-produced dynamic cone drivers whose limitations can hamper transient response and cause a non-uniform frequency response. QUAD's state-of-the-art planar magnet technology delivers a more natural and precise sound, making every detail of music playback audible.
