Important Safety Information

General Precautions

• Do not install the product in a confined space, such as a bookcase or built-in cabinet.
• Do not expose the batteries (battery pack or batteries installed) to excessive heat, such as sunshine, fire or the like for a long time.
• Do not dismantle, open or shred secondary cells or batteries.
• Do not expose cells or batteries to heat or fire. Avoid storage in direct sunlight.
• In the event of a cell leaking, do not allow the liquid to come in contact with the skin or eyes. If contact has been made, wash the affected area with copious amounts of water and seek medical advice.
• Secondary cells and batteries need to be charged before use. Always refer to the manufacturer’s instructions or product manual for proper charging instructions.
• After extended periods of storage, it may be necessary to charge and discharge the cells or batteries several times to obtain maximum performance.
• Dispose of properly.
• High volume may adversely affect your hearing.
• Do not use the unit while walking, driving, or cycling. Doing so may cause traffic accidents.
• Do not use in hazardous areas unless the surrounding sound can be heard.
• If water or foreign matter enters the unit, it may result in fire or electric shock. If water or foreign matter enters the unit, stop use immediately and consult your nearest Sony dealer. Be careful in the following cases:
  • When using the unit near a sink or liquid container: Be careful that the unit does not fall into a sink or container filled with water.
  • When using the unit in the rain or snow, or in humid locations.
• For details on the effects of contact with the human body from the mobile phone or other wireless devices connected to the unit, refer to the instruction manual of the wireless device.
• If the earbud tips are not securely attached, they may fall off and remain inside the ear during use. Make sure that the earbud tips are securely attached before use.
• Never insert the USB plug when the unit or charging cable is wet. If the USB plug is inserted while the unit or charging cable is wet, a short circuit may occur due to liquid (tap water, seawater, soft drink, etc.) or foreign matter on the unit or charging cable, and cause abnormal heat generation or malfunction.
• This product (including accessories) has magnet(s) which may interfere with pacemakers, programmable shunt valves for hydrocephalus treatment, or other medical devices. Do not place this product close to persons who use such medical devices. Consult your doctor before using this product if you use any such medical device.
• There is a danger that small parts may be swallowed. After use, store in a location out of reach of small children.
• Note about static electricity: If you use the unit when the air is dry, you may experience discomfort due to static electricity accumulated on your body. This is not a malfunction of the unit. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity.

Precautions

On Water Resistance

Unless the unit is used correctly, water may get into the unit and cause fire, electrocution, or malfunctions. Note the following cautions carefully and use the unit correctly.

Ensure that the USB Type-C® port cover is closed securely when you use the unit.

To Maintain Water Resistant Performance

• The USB Type-C port cover is important for maintaining water resistant performance. Make sure the USB Type-C port cover is closed securely when using the unit. If there is any foreign material on the cover or it is not completely closed, the water resistant performance cannot be maintained. Water may get inside and cause the unit to malfunction.
• 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.
• Do not place the unit in water or use it in a humid place such as a 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.

On Charging the Unit

Make sure to close the USB Type-C port cover securely after charging. Perspiration or water may cause damage.

Notes on Wearing the Unit

• After use, remove the headphones slowly.
• 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.

Other Notes

• 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.

Regulatory Information

For United States Customers

Supplier’s Declaration of Conformity

Trade Name: SONY
Model: YY2957
Responsible Party: Sony Electronics Inc.
Address: 16535 Via Esprillo, San Diego, CA 92127 U.S.A.
Telephone Number: 858-942-2230

This device complies with Part 15 of the FCC Rules. Operation is subject to the following 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.

NOTE: 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. This unit generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this unit does cause harmful interference to radio or television reception, which can be determined by turning the unit off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the unit and receiver.
• Connect the unit into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This unit must not be co-located or operated in conjunction with any other antenna or transmitter.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, 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 FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines.

For Customers in Canada

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.
