About the differences between the two types of earbuds

There are two different types of earbuds (supplied): standard-type and swimming type. The characteristics of each type

are as follows.

Standard-type earbuds:

You can use them in a wide variety of situations.

Swimming earbuds:

Employing a structure that prevents water penetration inside the headphones, Swimming earbuds allow you to enjoy

music more comfortably while swimming.

Note

The sound volume is lower with Swimming earbuds than with standard-type earbuds. Increase the volume as needed.

When you replace Swimming earbuds with the standard-type earbuds, the sound becomes louder. Adjust the volume

so as not to hurt your eardrums.
