For Sale 2000 Ohm High Impedance Headphones ( Headsets)
Also High Impedance Crystal Headphones (Piezoelectric Headphone)
Also Crystal Radio Earphones For Sale
Both the 2000 Ohm Impedance Headphone and the Ceramic Headphones were made special for me by a manufacturer. As with anything special made and not purchasing 10 thousand or more of them at a time the cost was high.
For sale Mono 2000 Ohm High Impedance Headphones with 1/4 inch plug ends. The High Impedance Headphones have an Impedance of 2000 Ohm. The cord is about 30 inches long.
My crystal radio set with a 12ft antenna connected to it will operate the 2000 Ohm High Impedance Headset without the use of a matching transformer and the sound quality is much better than the sound from my ceramic earphones. However improved performance can be obtained if used with a matching transformer. A better option for a direct connection to a Crystal Radio without a matching transformer would be my Piezoelectric ( Ceramic Headphones ). The best impedance I have others test them at is around 8,000 to 11,000 ohms at 1Khz.
Because my primary sales are for Crystal Radios I sell these 2000 Ohm Headphones as Crystal Radio Headphones. However many Amateur Radio and Ham Radio operators use them.
2000 Ohm High Impedance Headphones are rare and hard to find. Most are older or antiques. These High Impedance Headphones are not studio quality but intended for general use and listening.
These High Impedance Headsets are light weight and have foam covered Headsets.
The 2000 Ohm High Impedance Headphones makes them usable with my MK484 AM Radio Ic without a audio amplifier. However a amplifier will produce much more volume.
Such high impedance headphones are called sound powered headphones.

High Impedance Piezoelectric Headphones
These are High Impedance Ceramic Headphones. They have an DC resistance of over 20 Million Ohms similar to the above earphones there tested impedance is around 8,000 to 11,000 ohms. They have 1/4 inch mono plug ends and the cord is about 40 inches long. These are very good Crystal Radio Headphones.
Please note if these are not opperated from a transformer you need a resistor across the headphone input. Most crystal radios have a resistor in the audio output, if not add a 47K to 100K resistor.
Part # 1/4Jack-1, Mono 1/4 Phone Jack for the High Impedance Headphones Price $1.97 Each
Crystal Radio Earphones
High Impedance Earphones Piezoelectric type with a DC Resistance of over 20 million ohms and there impedance measures around 16,000 to 20,000 Ohms . Works in Crystal Radios and Fox Hole Radios and also good for low power drain electronic devices.
Please note if these are not opperated from a transformer you need a resistor across the input. Most crystal radios have a resistor in the audio output, if not add a 47K to 100K resistor.
