### ⭐⭐⭐⭐⭐ Review
*by C***E on 8 October 2025*

Batterie parfaitement compatible avec le casque WH-1000XM3. Je l'ai montée dans mon casque pensant que le problème de démarrage de ce dernier (rien ne se passait quand j'appuyais sur les boutons) venait de la batterie. En fait, il s'agissait d'un problème de mauvaise isolation des câbles internes du casque (vernis isolant qui se détériore avec le temps et les vibrations, ce qui provoque - sans doute - des courts circuits qui altèrent le fonctionnement du casque) : ce problème est documenté sur Internet. Après ajout de ruban isolant à plusieurs endroits que je jugeais critiques, le casque a fonctionné de nouveau. Reste à voir ce qui se passera sur la durée.
