Default headphone that shipped with DC2 Walkman?

those are the MDR-40

 

Confirm

 

Hi automaton. Here is the DC-2 box and the original headphones that came with it. As too cool 4 says they also came with the d-6c.

 

and a mystery ... on Mdr 40 catalogue ... and with original box.. the Mdr 51...With transport from Japan they are transformed ... I'm kidding. At this point I assume it was sold with both headphones in question

 

I think you must be right. What the sound difference is I have no idea because I never use supplied phones with any of my units. Maybe someone could tell us.
