Without Peer in the Industry: 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.

Tailored for Customization: Easy Monitoring of Settings, Multiple EQ Choices, and Bypass Mode
Clearly and easily view input source, input level meter, battery level, output volume, and EQ setting from the home screen. Meanwhile, a host of EQ settings offer fine-tuning. 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. You can also further refine your listening experiences with four customizable EQ settings that allow you to shape and tune your music to suit your tone preferences.

Loaded With Accessories
The KSE1500 comes with a variety of cables, protective cases, adapters, and earphone sleeves for a customized listening experience as well as a wall charger, polishing cloth, and durable bands to secure the amplifier to your mobile device.
