Crystal Earphone – High Impedance, 3' Cord
High-Sensitivity Crystal Earphone for Crystal Radios and DIY Projects
Discover crisp and clear audio even from weak sources with this high impedance crystal earphone. Designed for easy use in crystal radios, science projects, and other DIY audio devices, this earphone delivers reliable performance where modern headphones might not work.
Key Features
- High Impedance: Approximately 20K Ohm, perfect for circuits with low power output
- Piezoelectric Element: Sensitive to even very weak signals, ideal for crystal radio sets and early transistor radios
- 3-Foot Cord: Gives you plenty of length for comfortable use with your project or experiment
- 3.5mm Mono Plug: Standard mono plug can be used as-is or cut off for access to bare wires
- Comfortable Earpiece: Designed to fit directly into your ear canal for optimal sound
Technical Specifications
- Impedance: 20K Ohm (approximate)
- Plug Type: 3.5mm mono (cuttable for bare wire use)
- Cable Length: 3 feet
- Quantity: 1 earphone per package
- Vetco Part Number: VUPN8535
How to Use
- Simply plug the earphone into your crystal radio or audio device using the 3.5mm mono plug.
- If you need bare wires for your project, cut off the plug and connect the wires directly to your circuit.
- Place the earpiece gently into your ear canal for best sound performance.
This crystal earphone is a trusted choice for educational kits, science experiments, and vintage electronics enthusiasts. Its high impedance and piezoelectric sensitivity make it a go-to option for primitive or passive audio applications.
