Additional Information

Customer Review Summary

Beyerdynamic MM 1 (2023) is an impressive measurement microphone that consistently delivers accurate results. Compared to previous models like the Behringer ECM8000, the MM 1 offers a much more reliable and linear frequency response, particularly in the range of 60 Hz to 10 kHz. Although it has a slight boost in high frequencies (around 2-3 dB), this can be easily corrected by using the calibration file provided by Beyerdynamic upon request.

The build quality is robust and compact, making it easy to handle and transport. Users have noted that it performs exceptionally well for room analysis, PA tuning, and even as an ambient microphone for recording instruments like acoustic guitars and string quartets. It’s also suitable for live sound applications, with many stating it enhances the listening experience significantly.

One notable feature is the microphone’s need for a warm-up time after being powered on, with consistent measurements achieved after about 15-20 minutes. This characteristic is not a major issue but should be considered when using the mic for precise measurements.

Overall, the Beyerdynamic MM 1 is highly recommended for anyone looking for a budget-friendly yet high-quality measurement microphone. Its combination of accuracy, durability, and user-friendly features makes it a standout choice in its category.
