“Some 82 years in the waiting, it’s only fitting that Quad’s debut headphone arrives with a planar (though not electrostatic) driver in each earpiece – paying a certain homage to the speaker that out the brand on the map in the first place.”
QUAD has drawn upon its expertise with electrostatic loudspeakers to design its planar film diaphragm headphones, the ERA-1.
To ensure a natural sound in keeping with the company’s heritage, QUAD’s engineers have developed a planar magnetic drive film delivering fast, open and transparent performance, similar in quality to the famous ESLs.
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 array, designed to maximise sensitivity and consistency of the applied force over the driver area.
Musical Magnetism
When sound enters our ears, it has a planar wave front with all spectrum components in phase. A typical dynamic headphone driver disrupts this coherence with its phase irregularity, resulting in less than perfect signal peak reconstructions. QUAD’s planar magnetic driver has much better phase coherency, since all parts of the diaphragm are vibrating in concert without break up and delayed resonance.
Quad Equals Quality
QUAD audio components combine the assurance of tradition with the excitement of innovation, and the ERA-1 headphones are a perfect example. A choice of two ear cushions are provided – one made of soft leather, the other fashioned from latex with a soft, fleecy layer in contact with your ear. A high-quality, detachable 215cm cable is also supplied, together with a durable carrying case.
