These headphones came with mid-to-late 1970s Wurlitzer 206A student keyboards. One is branded Musitronic, and the other is branded Wurlitzer, although they both were likely manufactured by Telex. They include a headset microphone, which is untested.
The Musitronic headphones are tested and working. The headphone aspect of the Wurlitzer-brand headphones is working, but there is a missing plastic piece, so they need repair.
Due to the age of these headphones, sound quality is not guaranteed.
