lean your earbuds and eartips
Please note: Take caution not to allow any moisture to enter the earphones through the ports. In addition, do not force any dirt or debris into the ports and do not blow air into or vacuum the earphones as this could risk damaging them.
1 Remove the ear tips and gently wipe them with a clean, damp cloth - using water or an alcohol-based solution.
Let the tips dry completely before you put them back on to the earbuds.
2 Start cleaning the earbuds using a dry soft brush to gently clear any debris out of the earbud driver grilles. Do not use brushes with any kind of metallic bristles.
3 Hold the earbuds with the grille facing down so that any debris can fall out of the earbud during the cleaning process. Do this gently to ensure that debris is not pushed further into the earbud.
4 If, after dry brushing, any wax remains, dip a cotton bud in surgical spirit, tap off excess fluid and then wipe the bud to remove the wax. The spirit will dry quickly and will not damage your earbuds.
5 Finally, take an alcohol wipe and wipe it all over the earbuds. This will clean any remaining dirt/debris and disinfect the earbuds.
6 Once the ear tips have dried completely, reattach them to your earbuds.
