BOYA BY-MM1 Cardioid Condenser Microphone

Based on the specification, here’s an analysis of the condenser microphone:

Physical Characteristics:

Dimension: Φ22*81mm, which means the microphone has a diameter of 22mm and a length of 81mm.

Weight: 86g or approximately 0.19lb, making it a relatively lightweight microphone.

Acoustic Characteristics:

Frequency Response: 35Hz to 18kHz +/-3dB, indicating that the microphone can capture frequencies within this range with an accuracy of +/-3 decibels.
Polar Pattern: Cardioid, which means the microphone is most sensitive to sound coming from the front and less sensitive to sound coming from the sides and rear.

Electrical Characteristics:

Sensitivity: -42dB +/- 1dB / 0dB=1V/Pa, 1kHz, which means that for every 1 pascal (a unit of sound pressure) at a frequency of 1 kHz, the microphone output voltage is 1 volt at 0 dB.
Signal-to-Noise Ratio (SNR): 76dB SPL, indicating that the microphone can pick up signals at a level of 76 decibels before they become obscured by background noise.


Output Connector: 3.5mm TRS and TRRS connector, which is a common connector type used for headphones and microphones.

Transducer Type:

Electret Condenser, which means that the microphone uses an electret material to generate an electric charge, rather than a traditional capacitor and biasing circuit.



The specifications and what’s in the box sections provide specific details about the product’s technical capabilities and physical components. This information is crucial for potential buyers who want to make an informed decision about whether the product meets their needs.

Here are some additional suggestions to consider:

* You could add a note about the sensitivity rating, such as “Sensitivity: -35 dB ± 3 dB (high sensitivity for clear audio capture)” to provide more context.
* For the impedance specification, you could add a note about compatibility with different devices, such as “Impedance: 100 ohms ± 20% (compatible with most smartphones and cameras)”.
* In the “What’s in the Box” section, you could consider adding a brief description of each component, such as “Shock mount: Dampens vibrations and reduces noise” or “Furry windshield: Reduces wind noise and windblast”.

This would provide more detailed information and help potential buyers understand the product’s capabilities and features better.
