Quad ERA 1, is the first planar magnetic headphones from the highly revered Quad brand, offering a frequency range of 10 to 40k Hertz. They are supplied with 2 pairs of different earpads (one made from soft leather and the other from latex, topped with a fleece fabric) for slightly different acoustics; the sound is tuned to match Quad's world-famous ESL range of loudspeakers.
Unlike ordinary headphones that use mass-produced dynamic cone drivers which can hamper transient response and cause an uneven frequency response, Quad's cutting-edge planar magnetic technology delivers a more natural and accurate sound, ensuring you hear every nuance of a recorded musical performance.
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 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.
Retailing at £600, it's obviously not in everyone's price range, but for the added quality and comfort, those who can afford it, it may well be worth it.
