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.
