DIY spy earpiece Answered
PLEASE HELP! THANK YOU
I want to make a SPY EARPIECE, like a hearing aid with an battery inside,a kind of electromagnetic receiver,that will work with an inductive neck loop set. It is too expensive for me to buy one.
Another possibility is using a bluetooth neck loop set.
It should look like ear pieces on these websites:
Thank everyone who participates in finding out the needed plans to make one and technical plans
