I don’t know what creates the better vibrations tbh, I just know from my own personal experience there isn’t enough difference for me to notice at max (while plugged in I mean, the thing’s very noticeably weaker running purely on battery.)
Not that I own a wired one personally for full disclosure (and therefore don’t have that much experience with it) but I’m talking from the minimal experience I do have combined with the numbers.
No I don’t.
