in details.
On water resistant of the unit
• The charging case and the USB transceiver are not water resistant.
• Unless the unit is used correctly, water may get into the unit and
cause fire, electrocution, or malfunctions.

To maintain water resistant performance
Carefully note the precautions below to ensure proper use of the unit.
• Do not splash water forcibly into the sound output holes.
• Do not drop the unit into water, and do not use underwater.
• Do not allow the unit to remain wet in a cold environment, as the
water may freeze. To prevent malfunction, make sure to wipe off any
water after use.

bathroom.
• Do not drop the unit or expose it to mechanical shock. Doing so may
deform or damage the unit, resulting in deterioration of water
resistance performance.
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
• Be sure to use the supplied USB Type-C cable.

• 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 wearing the earbud tips, the speaker diaphragm may produce a
click sound. This is not a malfunction.
