Shure KSE1500SYS-US Electrostatic Earphone System

The electrostatic earphone system consists of single-driver, electrostatic earphones matched to a digital-to-analogue converter with EQ control. It features audio playback settings and electrostatic technology, offering the most precise transient response available.

The KSE1500 is based on state-of-the-art electrostatic technology. Each single MicroDriver Sound Isolating electrostatic earphone features a virtually weightless, massless diaphragm, surrounded by an electrostatic field generated by back plates that manage charge oscillation. This technology provides the fastest, most accurate transient response available, resulting in unmatched audio clarity and detail.

Features:

• Four customizable settings to manage audio playback preferences
• D4-band parametric EQ features five preset settings
• Streamlined controls for quick and simple, user-friendly navigation throughout the amplifier settings
• The first application of electrostatic technology for Sound Isolating Earphones featuring a single MicroDriver design
• Extremely high correlation to the source audio provides unmatched audio clarity and detail; electrostatic technology provides the fastest, most accurate transient response available
• Integrated USB-rechargeable battery can conveniently charge from provided wall charger or computer, even when streaming USB audio from computer
• Lightweight, ergonomic earphone shape minimizes ear fatigue while comfortable Sound Isolating sleeves block up to 37 dB of ambient noise
• Custom-designed earphone cable specifically isolates each conductor
• Compatible with Mac, PC, iOS, and Android devices via included accessory assortment, featuring Micro-B to Lightning and Micro-B OTG cables
