Replacing the earbud tips
M-sized earbud tips come attached to the left and right headset units at the time of purchase. If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance. If any of this is the case, try the following.
When changing the earbud tips, try the earbud tip sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and right ears may be different. Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is comfortably situated as deep in the ear canal as possible.

The headset cannot be charged when the computer goes into standby (sleep) or hibernation mode. In this case, change the computer settings, and start charging once again.
If the indicator (orange) on the charging case lights up for about 3 seconds and then turns off when the left and right headset units are removed from the charging case, the remaining battery charge of the charging case is low. Charge the charging case.
If the indicator on the charging case does not turn on even when the left and right headset units are removed from the charging case, the battery charge of the charging case is empty. Charge the charging case.
If the headset is not used for a long time, the rechargeable battery usage hours may be reduced. However, the battery life will improve after charging and discharging several times. If you store the headset for a long time, charge the battery once every 6 months to avoid over-discharge.
If the headset is not used for a long time, it may take longer to charge the battery.
While charging, be sure to keep the charging case lid closed to prevent the battery of the charging case from being wasted.
If there is a problem with the rechargeable battery of the headset or the charging case and something unusual is detected during charging, the indicator (orange) on the charging case flashes. It is recommended to charge in a place with an ambient temperature between 15 °C and 35 °C (59 °F - 95 °F). Efficient charging may not be possible beyond this range. If the problem persists, consult your nearest Sony dealer.
If the headset is not used for a long time, the indicator (orange) on the charging case may not immediately light up when charging. Wait a moment until the indicator (orange) lights up.
22

If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult your nearest Sony dealer. Avoid exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shock. Never leave the headset in a parked vehicle. When connecting the headset to a computer, make sure to connect it directly to the computer with a USB Type-C cable. Charging will not be properly completed when the headset is connected through a USB hub. The headset and the charging case may become warm during charging or for a while after charging. However, this is not a malfunction. If you shake the charging case forcefully, you will hear a rattling sound; however, this is the sound of the headset units moving inside the charging case and not a malfunction.

Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case by the following operations.
If the remaining battery charge of the headset becomes low when the headset is removed from the charging case or while using the headset
If a warning beep sounds and the voice guidance says, "Low battery", charge the headset as soon as possible. When the battery becomes completely empty, a warning beep sounds, the voice guidance says, "Battery is empty", and the headset automatically turns off.
When you are using an iPhone or iPod touch (iOS 13 or later)
When the headset is connected to an iPhone or iPod touch via an HFP (Hands-free Profile) Bluetooth connection, you can check the remaining battery charge of the headset on an iPhone or iPod touch. For more details, refer to the operating instructions supplied with the iPhone or iPod touch. The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough estimate.
When you are using an AndroidTM smartphone (OS 8.1 or later)
When the headset is connected to an Android smartphone via an HFP Bluetooth connection, you can check the remaining battery charge of the headset on the smartphone. For more details, refer to the operating instructions supplied with the Android smartphone. The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough estimate.
Checking the remaining battery charge of the charging case
If the indicator (orange) on the charging case lights up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is about 20% to 1%. The charging case cannot sufficiently charge the headset with this remaining level of battery charge. If the indicator on the charging case does not light up when both headset units are removed from the charging case, or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the charging case is at less than 1%. The headset cannot be charged with the charging case in this case.
Hint
The remaining battery charge of the headset may be different on the left and right sides depending on how you use them. When checking the remaining battery charge on an iPhone/iPod touch or Android smartphone while using both headset units, the remaining battery charge of the headset unit with less remaining battery charge between the left and right headset units is displayed. When using only one headset unit, the remaining battery charge of the headset unit you are using is displayed.
You can also check the remaining battery charge of the headset unit and the charging case with the "Sony | Headphones Connect" app. Android smartphones and iPhone/iPod touch both support this app.
Note
If the headset and smartphone are not connected with HFP, the remaining battery charge will not be correctly displayed.
If you connect the headset to an iPhone/iPod touch or Android smartphone with "Media audio" (A2DP) only in a multipoint connection, the remaining battery charge will not be displayed correctly.
26

The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining battery charge.

Supported codecs
A codec is an "audio coding algorithm" used when transmitting sound wirelessly via a Bluetooth connection. The headset supports the following 2 codecs for music playback via an A2DP connection: SBC and AAC.
SBC This is an abbreviation for Subband Codec. SBC is the standard audio coding technology used in Bluetooth devices. All Bluetooth devices support SBC. AAC This is an abbreviation for Advanced Audio Coding. AAC is mainly used in Apple products such as iPhone that can provide a higher sound quality than that of SBC. When music in one of the above codecs is transmitted from a connected device, the headset switches to that codec automatically and plays back the music in the same codec. If the connected device supports a codec of higher sound quality than SBC, you may need to set the device beforehand to enjoy music with the desired codec from the supported codecs. Refer to the operating instructions supplied with the device regarding setting the codec.

Precautions
On Bluetooth communications
Bluetooth wireless technology is a short-range wireless technology that enables communication between digital devices, such as smartphones and computers. The maximum communication distance may vary depending on the presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic environment. Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off the headset 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.
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 audio playback on the headset 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. The headset 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. Bluetooth connections with all Bluetooth devices cannot be guaranteed.
Bluetooth devices connected with the headset 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 headset 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.
