To me, all ASMR content. You think it's going to give you little frisson tingles or at least be soothing and calm but I hate the mouth sounds (like lip smacks) and the acting is always terrible in the ones that are like pretending to be in a situation with you. And I don't get the ASMR bodily response.
It sounds great, but they are apparently so quiet, being that they actively absorb all ambient sound, that you can hear the blood moving through your veins and most people can’t stand it for more than half an hour.
It's like being ADHD, there's less stimulus so your brain starts trying to hear everything it can. This is why I listen to music or a podcast while I work lol
