Product Features
iF Design Award-Winning Diamond Cut Geometric Design

The case features a multi-faceted form inspired by diamond cuts. The combination of a matte body and precisely crafted metal parts creates a futuristic and sophisticated presence. Its ergonomic design ensures a comfortable grip that fits well in the hand.
Shock-Resistant Design with 1.2m Drop Test Clearance

The internal cushioning and reinforced, hollowed-out corners are engineered to efficiently disperse and absorb impact during drops. This design effectively protects AirPods Pro 3 from scratches and shocks.
Hybrid Material Fusing Soft and Hard Elements

A hybrid construction combining a flexible TPU shell with high-rigidity polycarbonate achieves superior shock resistance. The matte surface finish also helps prevent fingerprints.
High-Precision Lock Clip Prevents Accidental Opening

A precisely machined zinc alloy lock clip securely fastens the case, preventing unintended openings while in a bag or during transit. It opens and closes smoothly with a single touch, making it convenient to insert and remove AirPods. The clip has successfully passed over 20,000 opening and closing durability tests.
Comfortable Usability

Designed with precision to align with all AirPods Pro 3 functions, the case allows for charging, pairing, and checking the LED indicator without removal. It also features speaker holes to ensure operation sounds and alarms are not obstructed.
Wireless Charging Without Removing the Case

The case supports both wireless charging and USB-C charging, allowing for convenient power replenishment with the case on.
Detachable Strap for Convenient Portability
The main body is equipped with a metal strap holder, enabling the attachment of the included detachable strap. The strap is made from durable, military-grade nylon material. It can be attached to a wrist, bag, or belt loop, helping to prevent loss or drops while on the go. The strap length is approximately 10 cm (adjustable by ±2 cm).
Three Colors to Match Your Style
The case is available in three colors: black, grey, and translucent grey, which highlight its unique geometric design. Users can choose their preferred color to match their fashion.
