This is the smallest spy Micro Earpiece FM receiver ever made, that fits in the ear canal. It is able to receive a FM signal from a distance of up to 1000 m in open field.
The Micro earpice FM receiver doesn't need any of these: neckloop, wallet, bluetooth, wires on the body. You will have a full freedom of movement.
There is no way that someone to detect the signal that you are hearing in the spy micro earpiece receiver, because it has set a secrete frequency.
More details here.
I think the micro earpiece is superior to the inductive type, I think to buy one because I have difficult exams here in INDIA
