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 you put the headset into your ears 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
When the headset is connected to an iPhone or iPod touch over an HFP (Hands-free Profile) Bluetooth connection, it will show an icon that indicates the remaining battery charge of the headset on the screen of the iPhone or iPod touch. The display position is an example.
A: Remaining battery charge of the headset The approximate remaining charge is shown at 10 different levels. B through E are display examples. B: 100% C: 70% D: 50% E: 10% or lower (requires charging)
The remaining battery charge of the headset is also displayed on the widget of an iPhone or iPod touch running iOS 11 or later. 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 HFP Bluetooth connection, select [Settings] - [Device connection] - [Bluetooth] to display the remaining battery charge of the headset in 10 different levels such as "100%", "70%", "50%" or "10%" in the connected Bluetooth device column. The operation above is an example. For details, refer to the operating instructions of 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
When the headset is removed from the charging case, or when the lid of the charging case is opened or closed with no headset units stored, if the indicator (orange) on the charging case lights up, the remaining battery charge of the charging case is about 30% to 1%. The charging case cannot sufficiently charge the headset with this level of remaining battery charge.
29

When the headset is removed from the charging case, or when the lid of the charging case is opened or closed with no headset units stored, if the indicator on the charging case does not light up, the remaining battery charge of the charging case is 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 using both units of the headset, the remaining battery charge of the unit with less remaining battery charge between the left and right units is displayed. When using only one unit of the headset, the remaining battery charge of the 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. 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.

Precautions
On Bluetooth communications
Bluetooth wireless technology operates within a range of about 10 m (30 feet). 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.
