    Hey everyone, I picked up some vintage headphones at a garage sale this week. I can't find any info about them at all. I managed to find some info on the later JVC HM-200E (with the dummy head) model, but this model turns up nothing. What do I have in my hands in terms of collector's value and rarity? What year were they made? Why is nothing online? Anyone? The phones are in near-mint condition and sound great.I can't upload a picture for some reason, but I have pics of them.

The 200E version were launched in the 80's (japan) but there seems to be zero info about the 100E.
By the date, you can assume they were launched on the late 70's. Do they use batteries? 

 

[mattgravey]

Yes, they take 1 AA battery. They are red, and the box is white.

How's the sound? 
 
You may be the first to post info about such headphones, since no one have done it before.

      They sound fantastic, very analog and very warm. I have never heard a sound like this, incredible. Just wish I knew more about them. Anyone?
