Three types of earpieces are enclosed in the package.
You can choose the one that best suits your needs.
- Single Flange（2 size：S / M）
- Double Flange（1 size）
- Low rebound urethane（1 size）
Initially, the single flange size M is installed.
The double flange goes deeper into the ear, which may result in a better seal for some people.
Low-resilience urethane has a high degree of shrinkage, which makes it more sealed for some people.
