Summary
The BOYA BY-M1 is a great Lavalier microphone, that is suitable for interviews & videos with a single person. It has a 6-meter-long wire and works with various devices (smartphones, cameras, computers, etc.).
Though the BOYA BY-M1 is more expensive compared to simple Lavalier microphones – the audio quality & the long wire are worth the extra money.
The microphone operates using a battery. Some devices (such as smartphones) don’t require turning on the mic, while other devices (such as cameras) require switching to “Camera mode” which operates using the battery.
