WE RECOMMEND THAT YOU REMOVE THE SILICONE OR FOAM TIPS TO CLEAN THEM. YOU CAN SAFELY CLEAN THE EARTIPS IN WATER UNDER A TAP OR WITH A Q-TIP.The earplug itself should be cleaned using a damp cloth. If you see the need to clean the inside of the sound canal, be careful not to insert anything more than 5mm inside the canal, or you may damage the acoustic filter.It’s no panic if dBud gets wet, since there is no electronics inside. But the acoustic filter contains several meshes and small air channels, so we don’t recommend to submerge dBud in water for cleaning. If water gets trapped inside it will take time for your dBuds to dry out completely, and this may affect the performance.After cleaning, let everything dry on a towel before placing them in the storage case.
