Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Beyerdynamic MM 1.
Comparisons
-
The Beyerdynamic MM 1 microphone offers better long-term investment potential over entry-level models like the DBX RTA-M due to superior build quality and individual calibration files.
Source -
The Sonarworks mic shares its OEM with Superlux and Behringer ECM8000, while the DBX RTA-M matches the RTA-420, highlighting different entry-level origins.

Setup and maintenance
-
The Beyerdynamic MM 1 and DBX RTA-M are random incidence mics, best positioned at 70° or 90° off axis to avoid loading effects on the capsule.
Source -
It's crucial to avoid aiming random incidence mics like the MM1 directly at speakers; incorrect positioning may cause high-frequency issues.
Source -
Custom adapters for sound level calibrators can be made using a rubber stopper with a drilled hole, suitable for the Beyerdynamic MM 1's 9 mm capsule.

Features and functionality
User experience
-
Owners report that microphones like the Beyerdynamic MM 1, which come with individual calibration files, exhibit less unit-to-unit variance and improved measurement accuracy.
Source -
Variability in measurement response can be more influenced by mic placement changes than by the calibration file corrections, as shown by a one-foot mic move.
Source
Software and compatibility
-
Smaart can utilize microphone calibration files through the Microphone Correction Curves option in IO Config, though it's not deemed essential for general measurements.
Source -
Accurate dB SPL metering in SMAART requires calibrating the Beyerdynamic MM 1 with a calibrator to determine the microphone's sensitivity to volume.
