Earbuds come in close contact with your skin often and sometimes for long periods. This will over time cause build-up of dirt and grease that can affect performance and may cause skin irritation. Clean your earbuds regularly to keep them fresh and make them last longer.
Unplug any cables before cleaning the case. Make sure everything is completely dry before using the earbuds, putting the earbuds back in the case, or plugging in a USB charger.
Remove the silicone ear tips from the earbuds and clean them separately. Use a disinfectant wipe or a lint-free cloth, slightly damp with 70% isopropyl alcohol or 75% ethyl alcohol to gently clean the ear tips, the exterior surfaces of the earbuds and the case. Avoid getting moisture in any openings or in the speaker mesh. Carefully clean those areas with a dry and soft brush, or a cotton swab.
Do not use any sharp objects.
Do not use compressed air.
Do not use products containing bleach or hydrogen peroxide.
Do not submerge the earbuds in any cleaning agents.
