Review: Fatto reso, sentivo le cuffie troppo pesanti e poco comode da usare per ore di lavoro
Review: Casque en apparence de bonne facture, mais je n'ai jamais eu casque d'une aussi mauvaise qualité sonore. Au départ (sans driver) il est carrément inutilisable, ensuite une fois le driver installé (mis à jour, configuré) on arrive a peine à avoir un son médiocre. Je ne comprends pas pourquoi ce produit est en vente. Une honte.
