Maintenance
1. Cleaning:
Regularly clean your earbuds to maintain hygiene and sound quality. Gently wipe the earpieces and cable with a soft, dry cloth. Remove ear tips and clean them with mild soap and water, then allow them to dry completely before reattaching. Use a small, soft brush to carefully remove any earwax or debris from the earbud nozzles.
2. Storage:
When not in use, store your in-ear monitors in a clean, dry place, preferably in a protective case, to prevent tangling and damage to the cable and earpieces.
