How to care for the headphones

If the earbuds are not well-maintained and foreign substances (such as dust or earwax) build up, the volume may seem lower than usual or not heard at all, they may not charge properly, or the water resistant or dust proofing performance may be affected. We recommend you care for the headphones regularly to prevent these issues.

Before you start

• Use a soft dry cloth or cotton swab. If the headphones are extremely dirty, use a cloth slightly dampened with a diluted neutral detergent.
• Do not use solvents such as thinner, benzene, or alcohol, as they may damage the surface.
• Do not leave the headphones in a cold environment, as any water or moisture left on the headphones may freeze.
• To prevent malfunction, make sure to wipe off any water or moisture after use.

Instructions to clean your headphones

1. Remove the earbud tips
   Hold the earbud, and then twist and pull to remove the tip.
   
   

   Note: Do not pinch the end of the tip when removing it.

   
   
2. Clean the headphones.

   Note: If you have the WF-SP900 headphones, refer to the Help Guide for details on how to care for them after using them for sports such as swimming. Manuals are posted on your model support page.

   • Clean the charging port or USB port cover.
     • For Truly Wireless earbud headphones: If foreign substances such as dust, dirt, sweat, or moisture is left on the charging port, wipe it off immediately and let it dry at room temperature.

       Note: The charging case is not water resistant. If the earbuds are charged while there is water or moisture left on them, the water or moisture can enter the charging case which can cause the unit to malfunction, or cause corrosion of the earbuds and/or charging case. Please be aware that malfunctions resulting from water in the charging case is considered misuse and is not covered by the warranty.

     • For In-Ear headphones: If perspiration, water, or moisture is left around the USB port cover, wipe it off immediately and let it dry at room temperature. Otherwise, the charging function may be affected or not work at all.
       
       
       Notes:

       • Make sure the USB Type-C™ port cover (or the Micro-USB port cover) is closed securely when the headphones are not charging.
       • If you have the WI-SP510 headphones, refer to the Safeguard the WI-SP510 and avoid liquid damage by sealing the USB-cover article for recommendations about how to avoid liquid damage
   • Clean the earbud tips with a diluted neutral detergent and then thoroughly wipe off any moisture.
   • Clean dirt or debris off of the outside of the headphones with a soft dry cloth, or to remove excessive dirt, use a cloth slightly dampened with a diluted neutral detergent.
   • Clean the mesh of the earbuds (the parts where sound comes out) to remove dirt, earwax, or anything that may accumulated, being careful not to accidentally push dirt or debris into the earbuds.
     
     
     Note: Avoid excessive force, otherwise, the mesh may peel off or get torn.
   • Drain the sound outlet holes (for water resistant or dust proofing models only). Position the sound output holes facing downward towards a dry cloth, and then shake several times to get the water out.
     
     
     Note: If water remains in the sound output holes, the sound may become muffled or completely inaudible.
   • Drain the microphone holes (for water resistant or dust proofing models only). Turn the microphone hole downwards towards a dry cloth, and then gently tap it about five times.
     
     
     Note: Make sure that no water drops remain in the microphone hole, or it may cause corrosion.

3. Attach the earbud tips.

   1. Firmly insert the tip all the way.
      
   2. Make sure the tips are not loose or tilted in any way.
      
   3. Check to see if the headphones work properly.
