i have this case: http://www.ebay.com/itm/Hard-carry-case-for-panasonic-rpdj120-audio-technica-athsj5-athsj3-athfc700-/170848584626   it fits perfectly to the S500 and it is smaller than the case you linked, so i guess your case will fit as well.

thank you very much! :)

thank you for the fast answer.   i found some smaller cases and i don't know if it will fit... can you (or someone else) measure the size of the headphones when it is folded?   thanks!

Hi   just bought my HA-S500 few days ago (didn't receive it yet).   can you please recommend my a hard case for the earphones from EBAY ? i don't need a big case... just the minimum that fits these headphones well.   for example, is this one will fit...
