ProTechTrader is a small family business dedicated to our mission on electronics: to teach and provide.
ProTechTrader started with just one employee and kept it in the family for ten years. We are committed to supporting DIY, makers, and hobbyists of electronics. We are proud to provide components that can be tricky to find. Our premiere offering is the complete kits that we developed with Charles Platt for his book "Make: Electronics". Perhaps our biggest pride is our dedication to answering questions personally and directly with intent to teach.

Piezoelectric Ear Phone High Impedance Ceramic Piezo Ear Piece for Crystal Radios - Upgraded Brass Diaphram with All Soldered Connections
**Newly Designed Updated Model for 2023** Perfect to make electronics projects like Crystal or Transistor Radios High 20,000 ohm impedance with resistance over 20 million ohms and a capacitance of 15,000 pf Rated Sensitivity of 57db at 1KHz in the frequency range from 200 to 8,000Hz Classic style highly sensitive molded earpiece with 42-in twisted wire with pre-tinned bare wire connections. Piezoelectric earphones are also known as crystal earphones, ceramic earphone, and piezo earpieces are the most sensitive earphones. They are in fact many times more sensitive than even the most sensitive magnetic earphones, dynamic earphones, or electrostatic earphones that you may use on your iPod or iPhone. Sensitive earphones have a very high impedance, which is measured in ohms and should not be used directly with a modern amplified radio. Crystal Earphones are so sensitive and require so little power to operate that you would hear a small 'click' just by touching the two bare leads together.
New Upgraded Brass Premium Model
Redesigned to eliminate issues previously found in many piezoelectric earphones. Tin Diaphragm has been Upgraded to Brass Conductive Glue (used on lower models) has been replaced with all soldered connections Black Wire is Specific to the upgraded 2022 version

Bare Wire Connections For Crystal Radios and Other Science Experiments
Crystal radios will not work with modern earphones or 'earbuds' as they are designed to operate with amplified audio sources found in today's electronic devices. Crystal Earphones are used in the construction of the crystal radio and in some science experiments such as listening to electric fish.
