Selecting the earbuds

If the earbuds do not fit your ears correctly, low-bass sound may not be heard. To enjoy better sound quality, change the earbuds to another size, or adjust the earbuds position to sit on your ears comfortably and fit your ears snugly. The M size earbuds are attached to the headphones before shipment. If you feel the M size earbuds do not suit your ears, replace them with the supplied S or L size earbuds. When you change the earbuds, install them firmly on the headphones to prevent the earbud from detaching and remaining in your ear.

Sélection des protège-tympans

Si les oreillettes ne s’adaptent pas bien à vos oreilles, vous n’entendrez peut-être pas les sons très graves. Pour profiter d’un son de meilleure qualité, changez la taille des oreillettes ou réglez-les afin qu’elles s’adaptent bien à la forme de vos oreilles et qu’elles soient confortablement installées. Les oreillettes de taille M sont déjà fixées sur les écouteurs à l’achat. Si vous constatez que les oreillettes de taille M ne conviennent pas à vos oreilles, remplacez-les par les oreillettes de taille S ou L fournies.

Lorsque vous changez les oreillettes, fixez-les correctement sur les écouteurs pour éviter qu’elles se ne détachent et restent dans vos oreilles.
