i have an interest in older headphones and have picked up several from here and ebay. so lets post up some pics and a few comments for fun and info..

Sonic pro 90
got these off ebay. small on ear design. zero info, tho i found a clone by realistic (german brochure on Faust's wikiphonia site). 2 speakers in each cup, 20-22k. 1983 ish. the sound is very bassy, ok mids, surprisingly better than expected, not comfy

Realistic proIIa
another ebay find. i think this is a koss pro4aaa (triple a) rebadge. early 80s. 10-22k , 100 ohms. sound pretty much like a modern dj headphone, bass thump, some highs
(this pair has new earpads from a koss mv1)

realistic pro 60. 15-35k, 100 ohms. early 80s. a koss hv/1a rebadge. very bassy for an open phone, smooth sound, supposed to be top of the line for its time

The sonic pro also appears under the Alaric brand as well. I have seen it in wood and metal. Is that plastic?

its plastic. the speaker caps and yokes are metal. i have seen a similar 3-speaker pickering on ebay

AKG K160
got them from ebay, early 70's, not much bass but very happy with mids. I've not had them long but they are already my fav's for a long session because they are sooo comfy.

I found this (unclassified!) ministry of defence document...
that lists them as being used by submarine sonar operators.

This is much better than the porta pro.

What is that?

My first headphones were my father's Sennheiser HD-424's. I remember the yellow pads disintegrated, so i made some by cutting up bits of foam from elsewhere. The picture isn't of my pair, as they are in Australia.

Akg k180 late 60s.

From the brochue.

"The SCS approach.

Subjectively controllable sound

This means: The acoustically effective auditory volume (ie the volume between the headphone driver and the eardrum) can be infinitely varied by a turn of the adjusting knobs; this feature allowing, for the first time, the individual selection of your "seat in the concert hall" and the adaptation of the sound to your individual physiological acoustic taste."
