Basically I bought this microphone from someone else. The sound quality of this is moderate, but my work won't be done with this. I need a better quality one. And all the microphones of Ulanzi you find at this price are copies. Considering that, mine is also a copy. However, the sound quality is moderate and will get the job done. It is good for those who are starting content creation completely. But since I am not a content creator, this is not suitable for me. So even though it is a copy, you can start your journey with this at a very low price.
However, my advice is that there is no alternative to the Boya by m1 microphone for good sound in this budget. But this costs above 1000 Taka. The ones below 1000 Taka are copies. And if you want a wireless microphone above 1000 Taka, you can check out Ulanzi wm 10. This is moderately good. And if you want, you can buy mine and try it out. And please pray for me. Thank you
