hi people, ive just found a sony wm 503 with the original hard case but its missing the headphones, ive done a bit of research on which ones go with it and im coming up with the mdr a20 , but they have a different jack, would be very greatfull for any info
wm 503
They should have the same standard 2.8mm jack. What have you read?
The Sony WM-503 came in 2 versions! One was a cardboard box. This version came with a black vinyl cover and, Sony a MDR-A20 folding headset. Now. The other set is far nicer. This set has a hard plastic container, with a clear lid to see all the contents. The Sony WM-503 came with the Sony MDR-e454 earphones, and a gray bag with drawstrings. Either set has the exact same size stereo mini plug.
thanks dbxS, great help, ive got the one with the clear lid, just need to get the headphones for it now, thanks again
clear lid ? are you sure it's not a WM-504 ?
Assuming they mean the clear lid on the display case....

The 503 also shipped with the gen 1 earbuds too.

thats the one AO, i dont have the blue outer sleeve though, but do have the grey pull string bag for the headphones, will post pics sometime
