This is my favorite:Saturn - produits.

If your buying the kind of speakers that plug into the headphone slot in your computer, they're probably cheaper in Canada or ordering them on-line. Your going to pay a high value added tax in France.

If you're only going to be in France for a year, you may not want to invest in a lot of 220 Volt items. It may be more economical to purchase a $30. 300W step up/step down transformer.
