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.

Interface Features

  • Easy monitoring of settings.

    Clearly view input source, input level meter, battery level, output volume and EQ setting from the home screen.

  • Five EQ presets loaded standard.

    Flat, Low Boost, Vocal Boost, Loudness and De-ess presets offer easy access to the EQ settings you’ll most likely want to tweak. Or, enjoy pure analog audio in Bypass Mode, which bypasses digital processing.

  • Detailed personal control.

    Further refine your listening experience with four customizable EQ settings that allow you to shape and tune your music to suit your tone preferences.
