On BLUETOOTH communications

  • The 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.

  • Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off the neckband speaker 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.

  • The neckband speaker 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 neckband speaker must comply with the BLUETOOTH standard prescribed by Bluetooth SIG, Inc., and must be certified as compliant.

    • Even when a connected device complies with the BLUETOOTH standard, there may be cases where the characteristics or specifications of the BLUETOOTH device make it unable to connect, or result in different control methods, display, or operation.

  • Noise may occur or the audio may cut off depending on the BLUETOOTH device connected with the neckband speaker, the communications environment, or surrounding conditions.

  • Depending on the device to be connected, it may require some time to start communications.

  • When charging, the neckband speaker cannot be turned on and the BLUETOOTH function cannot be used.

  • Since BLUETOOTH devices and wireless LAN (IEEE802.11ax/b/g/n) use the same frequency band (2.4 GHz), radio wave interference may occur during use near devices equipped with a wireless LAN, which may cause a decrease in communication speed, noise, or connection failure.

Note

  • To use the BLUETOOTH function, the other BLUETOOTH device must support the same profile as the neckband speaker. However, even if the same profile is supported, the functions may differ depending on the specifications of the BLUETOOTH device.
  • Due to the characteristics of BLUETOOTH wireless technology, there is a slight delay between the playback of the audio and music on the transmitting side and the playback on the neckband speaker side.
  • Establishing a BLUETOOTH connection between the neckband speaker and a device with a built-in radio or tuner may cause noise in audio from the device. The neckband speaker should not be used with such a device via a BLUETOOTH connection.
  • When using the neckband speaker, keep it away from a device such as a radio or a tuner. Use of the neckband speaker in the vicinity of such a device may cause noise in audio from the device.
