The AES gives Shure the opportunity to present its new KSE1500 Electrostatic Earphone System.
Announced as featuring "unprecedented" Sound Isolating electrostatic earphones and a matched digital-to-analog amplifier, the KSE1500 promises high-fidelity portable audio ans a "simply luxurious sound, wherever you ares. Electrostatic technology is said to provide the fastest, most accurate transient response available, a technology never applied before to Sound Isolating earphones. Each earphone is said to feature a virtually weightless, massless diaphragm surrounded by an electrostatic field generated by back plates that manage charge oscillation, resulting in greater clarity and detail with a high correlation to the source audio.
The KSE1500 comes with a variety of cables, protective cases, adapters, and earphone sleeves for a customized listening experience, plus a wall charger, polishing cloth, and durable bands to secure the amplifier to your mobile device. MSRP is $2999.
