Charging the neckband speaker

The neckband speaker is equipped with a rechargeable built-in lithium ion battery. Charge the battery with a USB AC adaptor (commercially available) and the USB Type-C cable (supplied) before using the neckband speaker.

When using the neckband speaker for the first time, be sure to charge the built-in battery for more than 1 hour before turning on the neckband speaker.

  1. Connect the neckband speaker to an AC outlet to charge it.

    Connect one end of the USB Type-C cable (supplied) to the USB Type-C port on the neckband speaker and the other end to a USB AC adaptor (commercially available), and then connect the USB AC adaptor to an AC outlet.

    The neckband speaker supports USB AC adaptors capable of delivering an output current of 1.5 A.

    The (power)/(BLUETOOTH) indicator stays lit in orange while charging is in progress.

    The estimated charging time varies depending on the power output capacity of the connected USB AC adaptor (commercially available). In addition, it may take longer than the charging time stated below depending on the type and specification of the USB AC adaptor and USB cable. The charging time may differ from the time stated below depending on the ambient temperature as well.

    The following time is stated as a reference.

    • When a USB AC adaptor capable of delivering an output current of 1.5 A is connected, charging completes in about 4 hours* and the (power)/(BLUETOOTH) indicator goes out.

    • When using a USB AC adaptor (commercially available), make sure that it is capable of delivering an output current of 1.5 A or more. You can use a USB AC adaptor with an output current of 0.5 A (500 mA) or more and less than 1.5 A as well, but it may take a very long time before charging completes.

    * Time required for the empty battery to be fully charged (100%) while the neckband speaker is powered off.


    After you disconnect the USB cable from the neckband speaker upon completion of battery charging, be sure to close the cap securely.

    The cap plays a very important role in maintenance of the water resistant performance.

Checking the charging completion

If the built-in battery is fully charged when you connect the neckband speaker to an AC outlet with a USB AC adaptor (commercially available), the (power)/(BLUETOOTH) indicator lights in orange then goes out in about 1 minute.

  • When using the Android smartphone with OS 9.0 or later installed

    When the neckband speaker is connected with the Android smartphone via an HFP (Hands-free Profile) BLUETOOTH connection, tap [Settings] - [Device connection] - [Bluetooth] on the smartphone. The remaining battery power of the neckband speaker is displayed along with the connected BLUETOOTH device name. For details, refer to the operating instructions supplied with the Android smartphone.

    Note that the remaining battery power displayed on the smartphone may vary from the actual remaining battery power of the neckband speaker. Consider this information as a reference.

  • When using the iPhone with iOS 15.0 or later installed

    While the neckband speaker is connected with the iPhone via an HFP (Hands-free Profile) BLUETOOTH connection, the remaining battery power of the neckband speaker is displayed on the widget screen of the iPhone. For details, refer to the operating instructions supplied with the iPhone.

    Note that the remaining battery power displayed on the iPhone may vary from the actual remaining battery power of the neckband speaker. Consider this information as a reference.

Checking the built-in battery level of the rechargeable built-in battery by pressing the (power)/ (BLUETOOTH) button

While the neckband speaker is turned on, pressing the(power)/(BLUETOOTH) button triggers any of the following voice guidance in accordance with the remaining battery power.

  • 81% - 100%: “Battery fully charged”

  • 61% - 80%: “Battery about 80%”

  • 41% - 60%: “Battery about 60%”

  • 21% - 40%: “Battery about 40%”

  • 1% - 20%: “Battery about 20%”

Built-in battery life

See “Specifications” for the charging time of the rechargeable built-in battery and the BLUETOOTH device playback duration.

When the built-in battery is running low

When you hear a notification sound and voice guidance (Low battery) and the (power)/(BLUETOOTH) indicator starts flashing slowly in orange, the rechargeable built-in battery is running low. Charge the neckband speaker ahead of time.

When the remaining battery decreases to such a level that the neckband speaker cannot be turned on, you hear a notification sound and voice guidance (Battery is empty) and the neckband speaker automatically turns off. In such a case, charge the neckband speaker.

When you turn on the power, but the (power)/ (BLUETOOTH) indicator lights in blue for about 2 seconds and then the power turns off, the rechargeable built-in battery is empty. In such a case, charge the neckband speaker.

Hint

  • You can charge the neckband speaker's built-in battery by connecting the USB cable connected with the neckband speaker to a computer that comes equipped with a USB charging port as well. However, not all the computers are tested and found compatible with this procedure and the procedure is not applicable to home-built computers.

Note

  • Connecting the neckband speaker to an AC outlet or a computer automatically turns off the neckband speaker. While connected with a power source, the neckband speaker does not turn on.

  • The maximum power output will be lower when the built-in battery is running low.

  • In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the neckband speaker stop. To resolve these issues, disconnect the USB cable and connect it back again in an operating temperature between 5 °C and 35 °C (41 °F and 95 °F), and then charge the neckband speaker once again. Be aware that the room temperature may fall to 5 °C (41 °F) or lower especially in wintertime. Take the ambient temperature into consideration as well for charging the neckband speaker.

  • Do not charge the neckband speaker's built-in battery in places where water may splash on it. The USB Type-C cable (supplied) as well as the USB port behind the cap are not designed for water resistant.

  • Even if you do not intend to use the neckband speaker for a long time, charge the built-in battery to its full capacity once every 6 months to maintain its performance.

  • When the Android smartphone is configured to establish BLUETOOTH connections solely for music playback (A2DP), the remaining battery power of the neckband speaker is not displayed on the smartphone.
