Your earbuds need regular cleaning to perform well and last longer. Here's the safe way to do it without damaging sensitive components.
Pull off silicone or foam ear tips. Wash them separately with warm soapy water, rinse, and let dry completely.
Use a soft dry brush to sweep debris from the speaker mesh. Hold earbuds with the mesh facing down so debris falls out.
Use a dry cotton swab to clean around the edges of the speaker mesh and the charging contacts.
Lightly dampen a cloth with 70% isopropyl alcohol and wipe the outer surfaces. Do not let liquid enter any openings.
