On BLUETOOTH® communications

• Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this unit 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 audio playback on this unit 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.

On charging the unit

• After charging is complete, disconnect the USB Type-C cable.
• While connecting the USB cable, do not apply excessive force to the connection part.
• When connecting or disconnecting the USB cable, do not apply excessive force, such as by pulling the cable, and connect or disconnect the connector straight to the port to be connected.
• If the USB cable connector is deformed, such as by it being bent, stop use immediately.

On using the unit while charging

• While liquid such as water or sweat, or foreign matter such as dust is attached to the USB Type-C cable or USB port, charging the unit may cause serious accidents such as burns or injuries due to fire, electric shock, heat generation or ignition, or can be the cause of a malfunction.
• Note the following when you use the unit while charging: If you feel any abnormality, stop using immediately.
• Check that there is no dust or foreign matter inside.
• If the USB cable or port gets wet due to liquid such as drinking water or sweat while charging, disconnect the USB cable from the connected device immediately to stop charging (refer to diagram B, showing a hand disconnecting a wet cable).

Notes on wearing the unit

• After use, remove the headphones slowly.
• Because the headphones achieve a tight seal over the ears, forcibly pressing them against your ears or quickly pulling them off can result in eardrum damage. When wearing the headphones, the speaker diaphragm may produce a click sound. This is not a malfunction.

Other notes

• When you use the unit as wired headphones, use the supplied headphone cable only. Make sure that the headphone cable is firmly inserted.
• When disconnecting the cable, pull it out by the plug, not the cable. Otherwise the cable may break.
• When connecting the cable, make sure to fully insert the plug into the jack. If the plug is not fully inserted, the sound may not be output.
• Do not subject the unit to excessive shock.
• Do not apply weight or pressure to the unit for long periods, including when it is stored, as it may cause deformation.
• If you experience discomfort while using the unit, stop using it immediately.
• If you have any questions or problems concerning this unit that are not covered in this manual, please consult your nearest Sony dealer.
