The Shure KSE1500 Electrostatic Earphone System is a must for audiophiles who are on the go. Shure prides itself on producing highly accurate sound and these earphones also come with a high-resolution amplifier that displays the input source, battery life, volume, and more. The system offers five EQ pre-sets and a Bypass Mode for analog sound. We love the long-lasting quality that the Shure KSE1500 Electrostatic Earphone System offers. The KSE1200 features single‐driver electrostatic sound isolating earphones coupled with a compact, high voltage amplifier.
