See the KSE1500 in Action
The world’s first electrostatic
Sound Isolating earphones.
Electrostatic technology provides the fastest, most accurate transient response available. Until now, it has never been applied to Sound Isolating earphones.
Each earphone features a virtually weightless, massless diaphragm surrounded by an electrostatic field generated by back plates that manage charge oscillation. The result is unmatched clarity and detail with an extremely high correlation to the source audio.
Earphone Features
Breakthrough cable technology. Made of durable Kevlar™, all KSE1500 cables were painstakingly engineered to meet the particular needs of electrostatic technology in a portable form factor.
Exclusive pairing. With a 6-pin LEMO connector, the cable delivers the specific bias required by the electrostatic drivers. The earphones and amplifier create a unique system of components only compatible with one another.
True to the source. Electrostatic earphone technology delivers more accurate sound than dynamic or armature driver technologies.
Amplifier Features
Portability perfected. Sized comparably to your mobile device and durable enough for life on the go, the portable electrostatic amplifier makes great sound possible anywhere.
Easy control. Using just two simple touch points—the large, tactile top knob and side button—you can control all menu navigation.
High-resolution 24/96 ADC/DAC. Aligns with the exacting Japan Audio Society High-Resolution requirements for both analog-to-digital and digital-to-analog conversion.
Works with you. Rechargeable and compatible with your Mac, PC, iOS and Android devices.
