How to clean the Clan K1 earbuds?

US Support

Materials you'll need: a cotton swab and a dry cleaning brush (if you can't find a cleaning brush, a toothbrush can work instead).
Take off the earbud tips from the earbuds smoothly. Do not use excessive force when detaching them as they may tear.
Use a cotton swab and cleaning brush to remove any debris and foreign materials.
If any foreign materials are still present, try brushing the earbuds again to dislodge the remainder.
After you finish cleaning, assemble the earbud tip back on the earbud properly.
