KSE1500 Electrostatic Sound Isolating™ Earphone The premium KSE1500 Electrostatic Sound Isolating™ Earphone System is an electrostatic earphone and amplifier system with digital-to-analog-conversion (DAC) for use in-line with portable media players. Featuring single-driver electrostatic Sound Isolating™ earphones matched to a USB digital-to-analog-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, analog via a direct line in, or bypass entirely for a pure analog 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.
