Shure KSE1200 Electrostatic Earphone System

Overview

The Shure KSE1200 is a premium electrostatic earphone system combining single-driver electrostatic Sound Isolating earphones with a dedicated DAC/amplifier. Electrostatic technology delivers an unmatched level of detail, clarity, and transient response that conventional dynamic and balanced-armature drivers cannot achieve — reproducing audio with near-zero distortion across the full frequency spectrum.

Key Features

• Electrostatic technology: Class-leading clarity, detail retrieval, and transient accuracy unmatched by dynamic or balanced-armature designs
• Dedicated DAC/Amplifier (SHA900): High-voltage bias supply with built-in DAC for pure digital-to-analog conversion
• 4-band parametric EQ: Adjustable via the amplifier for personalized sound tuning
• Near-zero distortion: THD below 0.01% for transparent, reference-grade audio
