Can I use S1 without an international bank card?

Yes. Top up your OpenDunes balance in dinars with a CIB or Edahabia card, then spend it on S1 or any other model in the catalog from that same balance. No foreign card, no currency conversion, no subscription.

S1 is built by Fish Audio, released on Jul 29, 2026. OpenDunes serves it unchanged — same model, same weights, billed in dinars.
