Wearing In-Ear headphones or Truly Wireless headphones for a long time may cause itchiness or inflammation in ears. If you feel such symptoms, stop using the headphones immediately, and consult a doctor and/or Sony customer service.
We recommend removing the headphones regularly when you use them for a long time. We also recommend doing regular maintenance with the earbuds and headset to always use them when clean. For how to care for the headphones, refer to the product manual, Help Guide or support web site.
