### ⭐⭐⭐⭐⭐ Review
*by M***S on 7 February 2026*

Ces enceintes sont plus petites et plus légères que ce que j'aurais cru et c'est absolument parfait. J'en ai acheté 2 pour avoir une paire stéréo et la qualité sonore est formidable. J'ai testé avec du rock, du jazz et du classique et tous les styles sonnent à merveille, avec de belles basses bien définies. La connection Bluetooth avec mon iPhone et mon iPad fonctionne sans faille. Je n'ai pas pu tester au volume maximal car les voisins auraient porté plainte, mais ces enceintes sont vraiment puissantes. La façon dont s'attache la courroie de transport est inventive et géniale. Je suis très satisfait de mon choix.
