Balanced Cables for IEMs! 

All in ear monitors (IEMs or earbuds) are natively balanced, and many high end audio players support balanced playback, but fully balanced IEM cables are tough to find!  Our IEM products are balanced cables for the majority of IEMs on the market.  These IEMs use use a round coaxial (MMCX) connector or 092 dual pin connector.  If you are looking for balanced mode cables for another type of headphone, check this link.

Before ordering, please visually inspect your cable to ensure it looks like one of the above!

    We have made IEM cables on our own, by hand.  However the earpiece connectors are so tiny and fragile that it is difficult and time-consuming to terminate them correctly and reliably.  Special machinery, training and equipment are required to produce these in a cost effective manner.  After looking at a number of prototypes and samples from wire manufacturers, we chose a factory (in the US) to build IEM cables to our specifications.

    These use a thicker wire than you would normally find in an IEM cable. The wire itself is copper with silver plating for a smooth and crisp sound, and is wrapped around a Kevlar threaded core for physical strength.  Clear Teflon insulation surrounds the wires, being the best insulator with the lowest dielectric constant (for improved bass).  The Teflon insulated wires are covered in a clear plastic sheath for reduced microphonics.  We designed this wire for improved sound, reliability and comfort.

    The connectors are gold plated to avoid corrosion and improve longevity.  The solder joints are made with silver, lead free solder, and then the connector base is molded around the connector for improved reliability.  Made in this way, the connectors are fully sealed to avoid the ingress of dirt and contaminants, suitable for portable and outdoor use. 

    The earpiece connectors feature a short segment of resilient memory wire so that you can bend them to a shape of your liking for improved comfort. A clear tube lets you adjust the length of the Y split below the earpieces. 

    An ideal cable for those of you who wish to connect your IEMs to the Pono Player using balanced mode.

    Add a P-04 adapter (here, bottom of page) to use these cables with non-Pono Devices.
