QUAD ERA-1马上就要来了 - 耳机网-耳机大家坛

To create the ERA-1, Quad developed a planar magnetic driver, which they say has qualities akin to their ESL loudspeakers.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 magnet system. Many planar magnetic headphones require high-power amplifiers to drive them. The Quad ERA-1 combines high sensitivity with low impedance to enable them to be used with a wide range of partnering devices, from portable audio players to high-end headphone amps. Two types of ear cushion are provided – one made of soft leather, the other of latex topped with a fleecy fabric. A high-quality, detachable 215cm cable is also supplied, together with a carrying case.
