The KSE1500 - Electrostatic Earphone System from Shure is a premium electrostatic sound-isolating earphone and amplifier system designed to deliver the high-resolution audio to "on-the-go" audiophiles and audio enthusiasts. The electrostatic earphones feature a single driver that is matched to a USB digital-to-analog-converter (DAC) that converts analog or digital audio from portable digital audio sources or computers at resolutions up to 24-bit / 96 kHz. Streamlined controls allow for quick and easy navigation, while the enhanced audio control features an on-board four-band parametric EQ with five presets and four customizable setting to maximize audio playback fidelity. The amplifier can process digital audio via micro-USB, analog via direct line in, or bypass entirely for a pure analog signal without conversion.

The front-panel display provides easy monitoring of input source, input level meter, battery level, output volume and EQ settings. The premium housing is constructed from elegantly machined black anodized aluminum, while power is provided from an integrated rechargeable Lithium-Ion battery that can be conveniently charged from the included wall charger, or via USB while streaming audio from a computer. Compatible with iOS and Android devices, the KSE1500 ships with Lightning and OTG cables, as well as two 1/8" / 3.5 mm cables, an airline adapter, an attenuator, a 1/4" / 6.35mm adapter, two security bands, a microfiber cleaning cloth, and a leather carrying case.
