[tldr]
is the V8 sound card necessary for Condenser mic Bm800 setup?
or the mic I bought is some cheaplak china stuff?
shopee product


I used to record voice over for my vids directly using my mobile phone(p9+ huawei)
and I recently tried to upgrade my gear step by step and bought this Bm800(mic and stand only) from Shopee
but then i found the voice pickup is too low and get another phantom power(usb powered)
the voice pickup is ok by now, but it still doesn't sound as nice when i recording with my pc via Audacity, compared to using phone+mic.

the voice recorded to my pc is flat and mono, (pc+phantom power+mic+Audacity)
but with phone+mic there is too much noises and sounds the same with or w/o phantom power on (phone+phantom power+mic)
*recorded with only air-cond w/o fan



Sooo I wonder if the V8 sound card add-on offered necessary for Condenser mic Bm800 setup?
or the mic I bought is some cheaplak china stuff?
how to make voice recorded sounds better?(current workflow=Audacity-noise reduction, Pr-loudness normalise)
