I personally received an email from them and did research about their brand and "collaboration".

And I don't think there is a point in writing what these guys are doing. Since one of the people that got scammed, and is portrayed on their website as a "scammer", but in reality is just a victim of the scam, actually made a 3 long part video series about these guys - @caleynztv on YouTube

But basically, in short, they are impersonating a real brand called - TZ audio products (techzoneaudioproducts.com) and baiting people into their scam of buying the microphone.
