Whenever I have to suggest a cheap mic for vlogging, I undoubtedly go for Boya BY-M1.
This mic is easy to use and easy to carry. I still remember many times I kept this mic in my jacket pocket as a backup mic when I forget the primary mic.
The company claims the sound sensitivity of the mic to be 30 DB, but what I have found after using it for 3 and half months, it around 38.
So keep this in mind if you are going to purchase this mic.
If you ask me I will recommend this thing as a backup mic that you can easily carry around everywhere.
Setting up this thing is not difficult, you just have to plug this in and start recording. No synchronization and stuff like that are needed.
I was amazed this cheap mic comes with a lapel clip and a windscreen.
