What model of walkman headphones is this ?

What model of walkman headphones is this ? "Japan" on Jack

 

I this is for Sharp walkman ? But i'm not shure.

 

Thanks, so maybe i find a model of Walkman Sony with this headphones

 

This looks like a Sony MDR-4.
You can find it on ebay, quite often. The sound is nice but nothing special. Early '80s era.

 

Are you sure ?

There's no inscription "Sony" on this headphones. Maybe some models of Sony Headphones are wihout inscription "Sony", but im not sure, i don't know.

At a second look, I am not sure. The MDR-4 is a bit different, a more rounded design.
