Vintage German High impedance headphones. 4000 ohms. Crystal Set Radio

Description

Rare Vintage German High impedance headphones. 4000 ohms. Crystal Set Radio. Made in Baden Germany. Headset is in nice shape, a few flaws here and there due to age, cord has had heat shrink tubing applied in some areas where the outer sleeve cloth material deteriorated some. Cloth covering the wires and the wires themselves are fine. Its construction is a cloth sleeve over two separate cloth covered flexible wires, like all headsets of the early era. The only issues were with the outer sleeve. Headset has been tested and works fine. These are high 4000 ohm type, the average for magnetic headphones is 1100 to 2000 ohms. Higher type are hard to come by. Depending on your Crystal radio set up the extra load can help or not help reception and loudness, it all depends etc. These will also work on most regular powered radios to my surprise, I tried it on a mini portable mp3 player.
