Tips for Size Choosing

Each person's ear canal size is different, and even the left and right ears also vary in size.
The age reference in the Size Chart is based on averages; it is not the absolute standard.
There may be several sizes that are suitable for your ear canal. Please find the most comfortable size.
If having an issue with improper size, please consult us first providing with the user’s age and gender. We will provide you with a satisfactory solution.

Highly recommend Mixed-Size Pack if it is your first time buying our earplugs.
