Shure KSE1500 Electrostatic Earphone System

2 Year Local Warranty.


The premium KSE1500 Electrostatic Sound Isolating Earphone System is an electrostatic earphone and amplifier system with digital-to-analogue-conversion (DAC) for use in-line with portable media players. Featuring single-driver electrostatic Sound Isolating™ earphones matched to a USB digital-to-analogue-converter (DAC) for extreme audio clarity and detail with fast, accurate transient response. The KSE1500 system features a 24 bit/ 96 kHz conversion rate, customizable 4-band parametric EQ with 5 preset settings and 4 user-defined settings, rechargeability and input level meters. Able to process both digital audio directly via micro-USB, analogue via a direct line in, or bypass entirely for a pure analogue signal without conversion. The KSE1500 system defines a new standard of portable listening that brings high-fidelity audio into the mobile demands of today’s active lifestyles.


The first application of electrostatic technology for sound isolating earphones featuring a single MicroDriver design (patented)

  • Each earphone features a virtually weightless, massless diaphragm, surrounded by an electrostatic field generated by back plates that manage charge oscillation.
  • The application of this technology to Shure Sound Isolating™ earphones is proprietary with a patent pending


Extremely high correlation to the source audio provides unmatched audio clarity and detail

  • Electrostatic technology provides the fastest, most accurate transient response available.


Lightweight, ergonomic shape minimizes ear fatigue 

  • KSE1500 Earphones support after-market custom-molded sleeves


Custom-designed cable specifically isolates each conductor

  • Allows for low capacitance and high dielectric properties with exceptional durability
  • Reinforced cable
  • 55” (1.4 m) long
  • Formable wire for secure, custom fit in over-ear earphone placement


Sound Isolating™, comfortable sleeves block up to 37 dB of ambient noise

  • Eight different types of sound isolating sleeves are included for secure and comfortable listening


Designed for use exclusively with the KSA1500 DAC amplifier

  • The KSA1500 features unique electrical circuit properties that deliver the specific bias voltages required by the single-driver electrostatic earphones
  • 6-pin LEMO connection



KSA1500 DAC Amplifier

4-band Parametric EQ features five preset settings and four customizable settings to maximize audio playback fidelity

  • Preset settings include flat, low boost, vocal boost, loudness, de-ess
  • Each user-defined setting features four customizable EQ points allowing detailed personal control, shaping and tuning for different musical tone preferences


EMI (Electromagnetic Interference) Filter

  • Special designed circuitry filters out Electromagnetic interference from mobile phone without scarifying the audio quality.
