Precautions

On Bluetooth communications

  • Bluetooth wireless technology is a short-range wireless technology that enables communication between digital devices, such as smartphones and computers. The maximum communication distance may vary depending on the presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic environment.
  • Depending on the Bluetooth device connected to the headset, the communication environment, and the surrounding conditions, noise or sound cut out may occur.
  • The maximum communication distance of the headset is approximately 10 m (32.8 ft). The communication distance may vary depending on the surrounding environment.
  • Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off the headset and other Bluetooth devices in the following locations, as it may cause an accident:
    • in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near fire alarms.
  • When you use the headset on an airplane, follow flight crew directions. Radio waves may affect instruments, causing risk of accident due to malfunction.
  • The audio playback on the headset may be delayed from that on the transmitting device, due to the characteristics of Bluetooth wireless technology. As a result, the sound may not be in sync with the image when viewing movies or playing games.
  • The headset supports security functions that comply with the Bluetooth standard as a means of ensuring security during communication using Bluetooth wireless technology. However, depending on the configured settings and other factors, this security may not be sufficient. Be careful when communicating using Bluetooth wireless technology.
  • Sony shall assume no responsibility for any damages or loss resulting from information leaks that occur when using Bluetooth communications.
  • Bluetooth connections with all Bluetooth devices cannot be guaranteed.
    • Bluetooth devices connected with the headset must comply with the Bluetooth standard prescribed by Bluetooth SIG, Inc., and must be certified as compliant.
    • Even if a connected device complies with the Bluetooth standard described above, the connection may fail depending on the characteristics and specifications of the device. Additionally, differences in operation methods, display, or performance may occur.
    • When using the headset to perform hands-free talking on the phone, noise may occur depending on the connected device or the communication environment.
  • Depending on the device to be connected, it may require some time to start communications.

Note on temperature rise

  • The temperature of the headset and the charging case may rise while charging or when using the headset for a long period of time. This is not a malfunction.

Note on sound leakage

  • When the volume is increased, sound may leak due to the structure of the driver unit part of the headset. Be careful not to raise the volume too much.

Note on static electricity

  • If you use the headset when the air is dry, you may experience mild tingling in your ears. This is not a malfunction of the headset, but is caused static electricity accumulated on your body. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity.

Notes on wearing the headset

  • Long-term use of the headset may cause symptoms such as itching and irritation in the ears.
    If you experience any of the above symptoms while the headset is in use, stop using it immediately. Then, consult a doctor, the Sony support contact, or your nearest Sony dealer.

  • Depending on the signal conditions of your smartphone or the surrounding environment, you may not be able to use the headset.
  • The Bluetooth function may not work with a mobile phone, depending on the signal conditions and the surrounding environment.
  • Do not blow on the driver unit.
  • If you experience discomfort while using the headset, stop using it immediately.
  • The headset is not waterproof. If water or foreign matter enters the headset, this can result in burnout or malfunction. If water or foreign matter enters the headset, stop use immediately. Then, consult the Sony support contact or your nearest Sony dealer. In particular, be careful in the following cases.

    • Benzine and other similar substances

Do not use the headset units and charging case near medical devices

  • Radio waves can affect cardiac pacemakers and medical devices. Do not use the headset and charging case in crowded places such as crowded trains or inside a medical institution.
  • The headset units and charging case use magnets. These magnets may interfere with pacemakers, programmable shunt valves for hydrocephalus treatment, or other medical devices. Do not place the headset units and charging case close to persons who use such medical devices. Consult your doctor before using the headset if you use any such medical devices.

Keep the headset units and charging case away from magnetic cards
