Precautions
On BLUETOOTH® communications
- Bluetooth wireless technology operates within a range of about 10 m. The maximum communication distance may vary depending on the presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic environment.
- Bluetooth communications may not be possible, or noise or audio dropout may occur under the following conditions:– When there is a person between the unit and the Bluetooth device. This situation may be improved by positioning the Bluetooth device so that it faces the aerial of the unit.– When there is an obstacle, such as a metal object or a wall, between the unit and the Bluetooth device.– When a Wi-Fi device or microwave oven is in use, or microwaves are emitted near the unit.– Compared to use indoors, use outdoors is subjected little to signal reflection from walls, floors, and ceilings, which results in audio dropout occurring more frequently than use indoors.– The aerial is built into the unit as indicated by the dotted line in the illustration (Fig. [A]). The sensitivity of the Bluetooth communications can be improved by removing any obstacles between the connected Bluetooth device and the aerial of this unit.
- Bluetooth and Wi-Fi (IEEE802.11b/g/n) devices use the same frequency (2.4 GHz). When using the unit near a Wi-Fi device, electromagnetic interference may occur, resulting in noise, audio dropout, or the inability to connect. If this happens, try performing the following remedies:– Establish a connection between the unit and the Bluetooth device when they are at least 10 m away from the Wi-Fi device.– Turn off the Wi-Fi device when using the unit within 10 m of the Wi-Fi device.– Position the unit and the Bluetooth device as near as possible to each other.
- 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.
- This product emits radio waves when used in wireless mode. When used in wireless mode on an airplane, follow flight crew directions regarding permissible use of products in wireless mode.
- The unit 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.
- Connection with all Bluetooth devices cannot be guaranteed.– Bluetooth devices connected with the unit 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.– When using the unit to perform hands-free talking on the phone, noise may occur depending on the connected device or the communication environment.
- Depending on the device to be connected, it may require some time to start communications.
If sound skips frequently during playback
- The situation may be improved by changing the wireless playback quality settings or fixing the wireless playback mode to SBC on the transmitting device. For details, refer to the operating instructions supplied with the transmitting device.
- When listening to music from a smartphone, the situation may be improved by closing unnecessary apps or restarting the smartphone.
On the use of calling apps for smartphones and computers
- This unit supports normal incoming calls only. Calling apps for smartphones and computers are not supported.
On charging the unit
- This unit can be charged using USB only. A computer with a USB port or a USB AC adaptor is required for charging.
- Be sure to use the supplied USB Type-C cable.
- When charging, the unit cannot be turned on and the Bluetooth and noise cancelling functions cannot be used.
- If the unit is not used for a long time, the rechargeable battery may become depleted quickly. The battery will be able to hold a proper charge after it is discharged and recharged several times. When storing the unit for a long time, charge the battery once every six months to prevent over-discharge.
- If the rechargeable battery becomes depleted extremely quickly, it should be replaced with a new one. Please contact your nearest Sony dealer for a battery replacement.
If the unit does not operate properly
- Follow the procedure below to reset the unit (Fig. [B]).Press the
and NC/AMB buttons simultaneously while the unit is charging. The unit is reset. When the unit is reset, the pairing information in the unit is not deleted. - If the problem persists even after the unit is reset, perform the procedure below to initialize the unit.Disconnect the USB Type-C cable and turn off the unit. Press and hold the and buttons simultaneously for at least 7 seconds. The indicator (blue) flashes 4 times, the unit is initialized, and the unit is reset to the factory settings. When the unit is initialized, all pairing information is deleted.
- After the unit is initialized, it may not connect to your iPhone or computer. If this happens, delete the pairing information of the unit from the iPhone or computer, and then pair them again.
On the noise cancelling function
- The noise cancelling function senses external ambient noise (such as the noise inside a vehicle or the sound of air conditioning inside a room) with built-in microphones, and produces an equal-but-opposite sound that cancels out the ambient noise.– The noise cancelling effect may not be pronounced in a very quiet environment, or some noise may be heard.– The noise cancelling function works for noise in the low frequency band primarily. Although noise is reduced, it is not cancelled completely.– When you use the unit in a train or a car, noise may occur depending on street conditions.– Mobile phones may cause interference and noise. Should this occur, locate the unit further away from the mobile phone.– Depending on how you wear the unit, the noise cancelling effect may vary or a beeping sound (howling) may occur. If this happens, take off the unit and put it back on again.– Do not cover the microphones of the unit with your hands or other objects. Doing so may prevent the noise cancelling function or the Ambient Sound Mode from working properly, or may cause a beeping sound (howling) to occur. If this happens, take your hands or other object off of the microphones of the unit (Fig. [C]).
Notes on wearing the unit
- 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
- Do not subject the unit to excessive shock.
- When you use the unit as wired headphones, use the supplied headphone cable only. Make sure that the headphone cable is firmly inserted.
- The Bluetooth function may not work with a mobile phone, depending on the signal conditions and the surrounding environment.
- 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.
- The earpads may be damaged or deteriorate with long-term use and storage.
Cleaning the unit
- When the outside of the unit is dirty, clean it by wiping with a soft dry cloth. If the unit is particularly dirty, soak a cloth in a dilute solution of neutral detergent, and wring it well before wiping. Do not use solvents such as thinner, benzene, or alcohol, as they may damage the surface.
- If you have any questions or problems concerning this unit that are not covered in this manual, please consult your nearest Sony dealer.
Replacement parts: earpads Please consult your nearest Sony dealer for information about replacement parts.
