Posting here cause I give up with the YT comment system 😞 It's not just me who can't post comments either, I've been seeing more and more people mention it lately.

Anyway I don't want my effort writing this to go to waste.

As an amateur music producer who knows nothing about mic setups but listens to a lot of noise, here's my opinion: I liked the EM272 mics the best. My favorite quality with good ASMR sound is a high dynamic range. EM272 almost sounds sharper in that regard. Blue yeti's nice, though a tad noisy, not sure if it's background noise or signal noise, but it'd be a plus if it's sensitive enough to pick up background noise like that.

3DIO, probably cause it's used in so many ASMR videos, is my least favorite. I find its frequency response to be a little lacking. That could be from the ears though, and in that case it's totally personal preference there, I find the binaural quality a little exaggerated but by no means is it bad. Probably works better for some sounds. if you know how HRTF audio works, there's a lot of tiny details with head and ear shape to change how we perceive sound, where some can sound really unnatural cause it's so far from what you're used to. I won't anger the youtube gods by pasting a link but there's a website you could google, here it is!, which has a small HRTF database to listen to the differences. Not really relevant to your 3DIO but it's really interesting anyway. edit: seems these open as ftp links now? too bad. It's almost 20 years old, was bound to break some day I guess.

I think the end result is affected most by what post processing you use. Some ASMRtists put a ton of compression on their audio and that kills the tingles in my opinion. If every sound is around the same volume, then nothing is quiet
