1970's walkman type earphones. (IP4)

Hello everybody,

The "loud" speakers in my laptop have spoken their last!

Does anybody, by any chance, have a redundant pair of those very light
weight delicate earphones that came with Walkmans (Walkmen?) type tape
players in the 70s/80s? The ones which had the phone bits, about an inch in
diameter, hidden inside little foam muffs (which tended to disintegrate).and
a flimsy sort of metal/plastic hoop bit which went over your head to hold
the whole lot in place.

It doesn't matter if the hoop bit is broken, or the wires missing or
whatever. I am only after the actual phone bits to try to graft them into
the laptop.

Any chances?

Many thanks,

Bob
