Due to the general characteristics of kernel-type / canal type earphones, depending on the user, when used for a long period of time, humidity inside the ear increases which may result in itchiness or inflammation due to increased moisture in the ear.
If such symptom occurs on your skin, stop using the headphones immediately, and consult a doctor.
We recommend removing the headphones regularly if you wear them for a long time. We also recommend doing regular maintenance with the Headphones. For how to care for the Headphones, refer to our Headphones Maintenance Tips.
