LISTENING TO AUDIO AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE AS LOW A VOLUME AS POSSIBLE. Over exposure to excessive sound levels can damage your ears resulting in permanent noise-induced hearing loss (NIHL). Please use the following guidelines established by the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before hearing damage occurs.

The Shure KSE1500 analog 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 KSA1200: a compact, portable, analog electrostatic amplifier for connecting to your preferred audio source. A full set of furnished accessories includes interchangeable sound isolating sleeves for a comfortable, personalized fit. From studio monitoring to casual listening, the KSE1200SYS reveals the detail and nuances to satisfy the most critical ears.
|① Power / Control Knob||Rotate to adjust volume level. Turn clockwise to turn unit on. Turn counter-clockwise all the way to turn the unit off.|
|② Status Indicator||
|③ Line Audio Input||3.5 mm stereo input for connecting to analog audio sources|
|④ Earphone Output||Lemo output to connect Shure KSE1500 earphones|
|⑤ DC Input||Connect to a computer, external battery, or AC power source using a USB type A to Micro-B cable to automatically recharge the battery.|
|⑥ Input Pad Switch||Select 0dB or -10dB. The pad attenuates the analog input signal to prevent clipping from high output audio sources. Enable the pad when the audio meter indicates clipping. Attenuate the source volume if the signal continues to clip with the -10 dB pad engaged.
Note: Use a high quality audio source for the optimal listening experience.
Plug into the amplifier with the amplifier powered off. This is recommended to avoid hearing damage.
Note: Align the red dot on the earphone cable connector with the red dot on the amplifier earphone output. To Disconnect from the amplifier: Pull the knurled connector collar up to safely release the lock on the earphone cable.
Plug the audio device into the LINE IN input.
To charge the battery while listening to audio, connect the amplifier to a computer, external battery, or AC power source.
Note: Volume should be adjusted only by using the amp volume knob for best performance. Ensure that volume is optimized in your audio source.
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.
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.
