so i found this headphones at the flea market today and since i couldnt find any info online i was wondering if anyone does know anything about them.
i bought them becouse they have the same earpads as the akg k140 and they where in good shape. also the headband looks similar to the one the k140 uses. this might be an akg oem?
unfortunately they came without a transmitter.

found it in this 1978 catalog: http://www.saba.pytalhost.com/1978/0045.jpg
its a infrared tv headset used with a transmitter mounted into saba tvs.
i'll probably use it for spares because i don't have such a tv.
