Voice Guidance: The factory default voice guidance language is English. Guidance is provided for power on/off, low battery, pairing, connection status, and battery level checks.

On BLUETOOTH® Communications: Microwaves from Bluetooth devices may affect electronic medical devices. Turn off the unit and other Bluetooth devices in hospitals, near priority seating on trains, in locations with flammable gas, near automatic doors, or fire alarms.

Audio playback may be delayed compared to the transmitting device due to Bluetooth characteristics, potentially causing desynchronization with video or games.

On Charging the Unit: Use the supplied USB Type-C cable.

Notes on Wearing the Unit: Forcibly pressing headphones or quickly removing them can cause eardrum damage. A click sound from the speaker diaphragm during wear is not a malfunction.

Other Notes: Do not apply weight or pressure to the unit for long periods to prevent deformation. Discontinue use if discomfort occurs. Consult a Sony dealer for issues not covered in this manual.

Licenses

The "Made for Apple" badge signifies that an accessory is designed to connect specifically to Apple products and meets Apple performance standards. Apple is not responsible for the operation or compliance of this device. This product contains software licensed by Sony under agreements with copyright owners.

FCC Compliance (for US customers)

This device complies with Part 15 of the FCC Rules. Operation is subject to two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This unit has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. If this unit causes harmful interference to radio or television reception, try to correct it by reorienting or relocating the receiving antenna, increasing the separation between the unit and receiver, connecting the unit to an outlet on a different circuit, or consulting a dealer or technician.

This unit must not be co-located or operated in conjunction with any other antenna or transmitter. This unit complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines.

Industry Canada Compliance (for Canadian customers)

This unit contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada's licence-exempt RSS(s). Operation is subject to the following two conditions: (1) This unit may not cause interference; and (2) This unit must accept any interference, including interference that may cause undesired operation of the unit. The available scientific evidence does not show that any health problems are associated with using low power wireless devices. However, there is no proof that these low power wireless devices are absolutely safe. Low power wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. The unit has been tested and found to comply with ISED radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio frequency (RF) Exposure rules.
