The Shure KSE1500 electrostatic earphones are the result of many years of research, development, and technological advancements from the Shure engineering team. The electrostatic drivers deliver premium quality, high definition audio for the first time in an in-ear design, which provides superior comfort and isolation from outside noise. The earphones are powered by the KSA1500: a compact, portable electrostatic amplifier with a built-in digital-to-analog converter for connecting to a micro-B USB source. A full set of furnished accessories includes a leather protective case, a micro-B USB cable, and interchangeable sound isolating sleeves for a comfortable, personalized fit. From critical monitoring to casual listening, the KSE1500 earphones reveal the detail and nuances to satisfy the most critical ears.

Plug into the amplifier with the amplifier powered off.
Note: Align the earphone cable connector with the red dot towards the front of the amplifier.
Set the INPUT switch to LINE for analog 3.5 mm sources or USB for digital sources.
|3.5 mm input (analog audio)||Plug the audio device into the LINE IN input and set the INPUT switch to LINE. To charge the battery while using an analog source, connect the amplifier to a computer or external battery
Connecting to an Analog Source
|USB (digital audio and power)||Use the USB cable when listening to music from a computer or other USB-equipped device and set the INPUT switch to USB. When connected to a computer, USB simultaneously streams digital audio and charges the amplifier battery.
Note: You have the option to disable automatic charging in the Utilities menu.
Connecting to a USB Source
The driver automatically installs when the amplifier is first plugged into a device. The KSE1500 should take over as the default audio device.
Note: Volume controls are disabled on Windows, Mac, and iOS. Volume should be adjusted only by using the amp volume knob for best performance. Ensure that volume is maximized in iTunes or the Windows Media Player.

The 4-band parametric equalizer is used to adjust the volume of independent, adjustable frequency ranges, to precisely shape the frequency response. Four user-defined presets can be saved in addition to four factory defined presets. The equalizer can be bypassed for a flat frequency response.
To view or edit an equalizer setting, select:
The equalizer consists of two filter types:
The following parameters are adjustable when creating an equalizer setting:
|① Frequency Point or Range||Four independent frequency points used to select specific frequency ranges.|
|② Frequency (Hz)||The numeric value of the selected frequency.|
|③ Gain / Cut||Adjusts the volume (±6 dB) of the selected frequency band.|
|④ Bandwidth / Q||Adjusts the width of the frequency band affected by gain settings
In this mode the equalizer is bypassed for an unchanged frequency response. When using an analog input source, bypassing the equalizer maintains a 100% analog signal path. For digital audio sources, the equalization section of the digital signal processor is simply disabled.
The limiter protects your ears from unexpected volume spikes at the earphone output.
The input pad feature is available when the amplifier is receiving analog audio in line input mode. The pad attenuates the analog input signal to prevent clipping from high output audio sources. Enable the pad when the audio meter indicates clipping.
Sample rate information is displayed here.

Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the firmware can be downloaded and installed using the Shure Update Utility tool. Software is available for download from http://www.shure.com/americas/products/software/utilities/shure-update-utility.
CAUTION! Ensure that amplifier power remains on during a firmware update. Do not turn off the amplifier until the update is complete.
The Shure Update Utility will find the latest versions of firmware. You can download the updates to your computer. Once the download is complete, the amplifier automatically begins the firmware update, which overwrites the existing firmware.
Note: ENABLE FW UPDATE must be enabled in order for the firmware update to work.
Note: The battery should be charged before updating firmware. Do not attempt to update firmware if battery percentage is less than 10%.
To avoid degrading battery health, keep the storage temperature range between 10°C to 25°C (50°F to 77°F).
Lithium-ion batteries have no “memory effect”, and instead experience a more linear reduction in capacity. Contact Shure Service and Repair to replace the battery if you experience any issues.
Connect to the amplifier: Align the red dot on the earphone cable connector with the red dot on the amplifier earphone output.
Disconnect from the amplifier: Pull the knurled connector collar up to safely release the lock on the earphone cable.
Select an earphone sleeve that provides the best fit and sound isolation. It should be easy to insert, fit comfortably, and easy to remove.
|Soft Flex Sleeves: In small, medium, and large sizes. Made from pliable rubber.|
|Soft Foam Sleeves: Compress the foam sleeve between your fingers and insert into the ear canal. Hold in place for about ten seconds while the foam expands.|
|Triple-Flange Sleeves: If desired, use scissors to trim the stem on the sleeve.|
Important: If there is a lack of low frequency response (bass), the earphone sleeve may not be forming a proper seal. Gently push the earphone deeper into the ear canal or try using a a different sleeve.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
The fit of the earphone can greatly affect sound quality.
Caution: If the barb or any of the nozzle is exposed, the sleeve is not properly installed. Replace sleeves if they do not tightly grip the nozzle. To ensure proper fit and performance, use only sleeves supplied by Shure (unless using custom molded sleeves).
Grasp the body of earphone and gently twist to remove.
Note: Do not pull on cable to remove earphone.
Careful maintenance ensures a tight seal between the sleeve and nozzle, improving sound quality and product safety.
If you notice a change in sound quality, remove the sleeve and check the nozzle of your earphone. If nozzle is blocked, clear obstruction by using wire loop end of cleaning tool.
If no obstruction is found or if sound quality does not improve, replace the sleeve with a new sleeve.
Caution: When cleaning, do not force any object through the earphone nozzle! This will damage the earphone sound filter.
Warning: The cleaning tool is only to be used to clean the earphones. Any other use, such as using the tool to clean ears or foam sleeve, could result in injury.
The cable connectors to the earphones may collect debris or other deposits that can affect audio quality. If this happens, disconnect the cables and clean them using a dry cotton swab.
