Precautions

Note on static electricity

  • If you use the headphones when the air is dry, you may experience discomfort due to static electricity accumulated on your body. This is not a malfunction of the headphones. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity.

Notes on wearing the headphones

  • After use, remove the headphones from your ears slowly.
  • Because the earbud tips achieve a tight seal in the ears, forcibly pressing them in or quickly pulling them out can result in eardrum damage. When putting on the headphones, the speaker diaphragm may produce a clicking sound. This is not a malfunction.
  • Long-term use of the headphones may cause symptoms such as itching and irritation in the ears.
  • If you experience any of the above symptoms while the headphones are in use, stop using them immediately. Then, consult a doctor, the Sony support contact or your nearest Sony dealer.
  • For long-term use, it is recommended that you remove the headphones from your ears on a regular basis.

Notes on the noise isolation earbud tips

  • As the earbud tips fit more snugly in your ears, you may feel a strain on your ears. If you experience discomfort, discontinue use.
  • Earbud tips are consumables and may deteriorate or break after long-term use and storage. If the earbud tips deteriorate or become damaged, the audio performance such as sound quality and noise canceling will become compromised. Replace them regularly.
  • If the following malfunctions occur, the earbud tip or a part of it may remain in your ear and cause injury or illness. If you see any damage, be sure to replace the earbud tip.
    • The earbud tip becomes damaged by cracking.
    • The earbud tip becomes damaged by peeling.
    • The earbud tip becomes damaged by chipping.
    • The earbud tip becomes damaged by the mesh tearing.
  • Avoid washing with water, wet wipes and use of organic solvents such as alcohol, as these can cause premature deterioration.
  • Foreign material such as earwax may attach to the mesh part of the earbud tip. As a result, the sound may become muffled or difficult to hear. In that case, remove the foreign material carefully.
    First, remove the earbud tip from the headphone. Then, apply a cotton swab lightly to the mesh part and rotate the cotton swab slowly to wipe off the foreign material. Be careful not to tear the mesh part.
