Listings most commonly show TPU (thermoplastic polyurethane), silicone, polycarbonate, and other plastics as the materials used for AirPods 2nd‑generation case covers.
Several listings include carrying attachments such as a carabiner or keychain; at least one option adds a faux‑pearl wrist chain as a wearable accessory.
Some covers use mechanical closures—secure locks, quick‑release latches, or lock clasps—to keep the lid closed. Other options rely on tight‑fitting sleeves or adhesive‑assisted hinges to hold the lid in place.
Some listings state a 1 Year Limited Warranty, and at least one listing mentions a Lifetime Limited Warranty in its product details.
Listings describe scratch‑ and scuff‑resistant surfaces, bump‑resistant or impact‑absorbing elements, dual‑layer designs (hard outer shell with softer inner layer), and some include raised edges or latch/lock mechanisms for extra retention.
