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.
