A fine oil-spray coat on the surface resists fingerprints and everyday stains. When marks do appear, a quick wipe with a damp cloth removes them cleanly — the cover looks fresh without any special cleaning products.

A small hook is included in the package that attaches to the case cover. Hook it to a bag strap, lanyard, or keyring so the case stays within reach without taking up extra pocket space — useful when going out with just the earbuds.

The cover is made using the real charging case as a mold, resulting in a tight, accurate fit that does not shift or loosen with daily use. All cutouts — charging port, lid hinge, LED indicator — are precisely positioned so the case never needs to be removed for charging or for opening the lid.

The soft silicone material is comfortable against skin and can be rinsed under water when it needs a deeper clean. It resists yellowing and color fading through regular use, meaning the cover continues to look new well into its lifespan without degrading.

Flexible silicone construction absorbs the energy of minor drops and bumps rather than transmitting it directly to the charging case. The material rebounds to its original shape immediately after impact without permanent deformation.
