Sony MDR-CD100 - what are these ?

[El Chupacabra]

I've searched the net for info on these headphones I have, and can't find anything. Sony support says it's an invalid model number, one that never existed... I know they exist, because I'm looking at them.

They are Sony MDR-CD100, from sometime in the mid- to late- 1980s. They look a lot like the MDR-V6 (which I also have): cheap vinyl cover on pads, "STUDIO MONITOR" printed across vinyl pad (that goes over the top of your head), and "for Digital" on a red metallic sticker on each cup. The cups pivot 2 ways but do not fold. The band is metal (silver), as are the cups (black). Quite sturdy overall. Approx. 9 foot straight cord, which runs to each cup, and terminates in a gold-colored 1/8" plug (with a screw-on 1/4" plug adapter). The cups are round (not oval like the MDR-V6), and smaller than the MDR-V6; they sit directly on the outer ear rather than encompassing the entire ear.

Anyone know where these originated ? I think they may have been Japanese-market. Just curious about what these are, where they came from... seemed odd to me that Sony denies their existence.

I had that happen to me with my MDR-D77, i would search them and find people that had them and some reviews but that was about it. Then after months of digging off and on i found some one that said "ive listen to the MDR-D77s and i dont liek eggos" so then after i did a search on eggo it was like everything poped up and i started to find them more and more. I dont know why but mine wernt known as eggo when i got mine but now they are known as eggos.

Onlythign i can find on yours is a picture, and i think i have used or had a set of those cans before. I remember that look and style

Yep, that's them in that picture (drawing?). Probably the main reason I'm looking for info on them is to see if Sony now makes a similar headphone, for which I can order replacement ear pads, since the ones on these MDR-CD100s are disintegrating (thin vinyl cover over foam pads).

The closest earpad match for that MDR-CD100 is the one that fits Sony's current MDR-7502 headphones.

Thanks ! I'll check with Sony parts for the replacement pads.
