It comes in at 3.41mm and length 9.92mm, but i aint sure that this is just an standard 3.5mm plug..
I recall i tried it with another 3.5mm plug some weeks back and it didnt line up, and it was the inner plug that didnt line up since its an pretty thick inner pin that teclast uses and the the spare 3.5mm plug i got was to thin in the inner dimesions and didnt wanne pushed it more, if the soldering went haywire..
the outer shell 3.5mm, but cant say if the inner pin is standard 3.5mm pin, its pretty thick pin ..
