- Smooth lid opening and closing
- Easy cable charging access
- Stable wireless charging
- Secure product retention
- Premium appearance
A small change in leather thickness, cutting position, or assembly accuracy can affect the final user experience. Proper fit testing and charging compatibility validation are essential to ensure every case performs reliably with real AirPods devices.
Common defect sources include:
- Incorrect AirPods model reference
- Excessive material thickness
- Poor cutting alignment
- Uneven adhesive application
- Incorrect inner dimensions
- Weak reinforcement structure
- Improper logo positioning
- Insufficient packaging protection
For OEM/ODM production, defect prevention should start during product development, not after bulk production.
