Please suggest a wireless mic for my requirements?

I record my videos on my iPHone 16 wherein I sing and play Harmonium side by side. Previously, on my android phone I was using a generic mic which was working very well but, recently I purchased iPhone 16 and that generic mic is not recording audio as it was recording on my android phone (it records a very low audio).

A few days back, I purchased Hollyland Lark A1 mic which is suitable for the podcast kind of recording but, in my videos it skips all the high notes everytime I try to record my video.

So, I had to return it. Please someone from the apple community help me out of it.

Regards,

Sudhir
