This screen guard is designed to protect the display of your audio player. It comes with a professional screen cleaning paper kit, including a wet wipe (Step 1) to remove excess dirt and a dry wipe (Step 2) for a clean finish, ensuring a bubble-free installation. The installation guide provides clear steps for application, including peeling off protection layers and correctly covering edges for crystal clarity. It is compatible with audio players featuring a display, such as the JBL earbud charging case shown.
