What are the benefits of the electrostatic earphone technology?

The KSE1500 is based on state-of-the-art electrostatic technology. Each single MicroDriver Sound Isolating electrostatic earphone features a virtually weightless, massless diaphragm, surrounded by an electrostatic field generated by back plates that manage charge oscillation. This technology provides the fastest, most accurate transient response available resulting in unmatched audio clarity and detail.

Which sources can be used?

KSE1500 is capable of processing digital audio via micro-USB as well as analogue audio via direct line in. It can also bypass entirely for a pure analogue signal without conversion. The featured USB digital-to-analogue-converter (DAC) converts analogue or digital audio from portable sources and computers.

Are they noise cancelling or sound isolating?

Shure earphones are based on the sound isolating principle.

Can I go for a custom mold?

Custom molds are not directly offered by Shure but there are partners in each country that offer custom molds.

How do I clean the Shure Sound Isolating Earphones?

Shure earphones furnish a cleaning tool. Use the wire loop of this tool to remove wax/debris build-up if you recognize any change in the overall output level. Make sure that you hold the earphone with the nozzle pointed downward while cleaning as it is desired to have the wax fall out of the nozzle, not accumulate in the center of the nozzle. When inserting the wire loop into the nozzle, the wire loop tip should rest against the edge of the damper; the side of the loop should rest against the side wall of the nozzle. Keep the wire loop tip against the edge of the damper/filter. Scrape the loop around the side wall while pulling it outwards to remove the wax. Do not press the loop deeper into the nozzle as this might puncture the damper/filter. Such damage will allow wax/debris to get into the transducer section of the earphone. Eventually, the audio signal will diminish or stop completely. At this point, the earphones must be sent to Shure Service/Repair.

I’ve got intermittent audio. How do I trouble shoot a potential fault?

Try to figure out if the defect comes from one of the earbuds or a connector. As soon as you may have diagnosed the point of failure, get in touch with your local Shure service center.

The earphones are noisy what should I do?

Try to clean the earphones using the furnished cleaning tool. If the sound does not improve, please get in touch with your local Shure service center.

What´s the max. attenuation of Shure earphones?

Shure Sound Isolating Earphones block up to 37 dB of background noise depending on the used sleeves.
