Thats how i found it , no battery i guessLooks like a mic to me,,,where is battery?
Nice find on the Nokia headset. I was just looking for the same thing! The UR mark made me suspicious too.Some observations and guesses.
There is a Nokia headset with a model number HS-105. This might be a part from that.
On the PCB, there is a UR mark, which I wouldn't think would be on a "bug."
Well, you have gotten our curiosity up; do you have any idea who put it there and why?Hye ,
The thing in th emiddle is what "the RB" said , its a button , its clickable.
so yeah i think its nothing.
