MiEMi-m7 & iSEMcon EMX7150
IEM measurement kit

MiEMi™ is a compact adapter that attaches to a standard measurement microphone, enabling accurate frequency measurements of both custom-fit and universal in-ear monitors—ideal for audio engineers, IEM dealers, and audiophiles who need a reliable way to test functionality, compare sets, or verify damage. Designed with the principles of lab-grade occluded ear simulators, MiEMi™ offers practical, affordable performance that integrates seamlessly into existing pro-audio workflows, giving users a missing tool for consistent, repeatable IEM testing without the high cost or fragility of traditional lab equipment.

MiEMi™ is a professional IEM measurement tool featuring an interchangeable microphone adapter for most standard measurement mics, EPDM O-ring sealing, tuning and distance spacers for frequency-response control, an inner container that stabilizes the assembly, and a custom EPDM rubber coupler that ensures a secure, airtight fit on custom-molded in-ear monitors. With MiEMi™, you can capture accurate reference traces of IEMs at their optimal performance point, compare units across artists or models, and identify deviations or errors over time.

For this guide, I’m assuming you have a functional measurement system & sound card set up. Make sure you’ve cleaned any goo or wax out of your IEM as this will affect your measurements.
