The 2000 Ohm High Impedance 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.

The 2000 Ohm High Impedance Headphones are mono 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 had others test the 2000 Ohm High Impedance Headphones 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.

    I bought a pair of this model a few years ago. Compared to the vintage phones I have, these fairly inexpensive headphones have both the best tone quality and the highest sensitivity. When used with a transformer to better load the coil, these phones will sound stations from 100’s of miles away. Better sound and dx. I haven’t found a better set of phones for crystal radio use yet. My highest recommendation. Buy these!

    These work great on my crystal radio and battery tube radio. More comfortable than the old plastic cans I have used since the 60’s.

    These are not 2000 ohms headphones each side Approximate 625 ohms Combine 1230 ohms . Purchased thinking 2000 no won’t do business again. Using on 6418 vacuum tube 18 volts on plate , my last pair real 2000 ohms radio was very loud, these Very disappointed

    • Those measurements sound accurate for DC resistance. These are 2,000 ohms AC audio impedance with approximately 1,200 ohms DC resistance.
