Bought this to help my grandson build his first crystal radio. He is still surprised he could make a real working radio.

They stop working after a week. Poor internal connections.
I thought my project was not working and waisted a lot of time troubleshooting.It was this earpiece bad from stock. I bought 2 of them and the second one also went bad in a week.
