OMG I just found the perfect mic for asmr: the tascam dr-05x. This mic creates good sound for both asmr and regular recording, and it can work on a regular phone! The mic itself is expensive but I guess I'll save up for it :)
I got this idea from my insessant need to watch asmr, and now I think I want to start an asmr channel but idk. I think I just want to rammble on about stuff or just do something instead of sitting around and on my phone. Instead, I can use my phone and a nice mic to start making videos for fun.
