Charging the neckband speaker

The neckband speaker is equipped with a rechargeable built-in lithium ion battery. Charge the battery with a commercially available USB AC adaptor and the supplied USB Type-C® cable 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 supplied USB Type-C cable to the DC input port on the neckband speaker and the other end to a commercially available USB AC adaptor, 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. Use of any other devices for battery charging is not guaranteed.

    The indicator stays lit in orange while charging is in progress.

    The estimated charging time varies depending on the power output capacity of the connected commercially available USB AC adaptor. 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 commercially available USB AC adaptor capable of delivering an output current of 1.5 A is connected, charging completes in about 4 hours* and the orange indicator goes out.

    • When using a commercially available USB AC adaptor, 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 that is required to charge the empty rechargeable battery to its full capacity and may vary depending on the usage of the neckband speaker.


    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 commercially available USB AC adaptor, the indicator lights in orange then goes out in about 1 minute.

  • When using the Android smartphone with OS 8.1 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 10.0 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

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

  • 91% - 100%: “Battery fully charged”

  • 81% - 90%: “Battery about 90%”

  • 71% - 80%: “Battery about 80%”

  • 61% - 70%: “Battery about 70%”

  • 51% - 60%: “Battery about 60%”

  • 41% - 50%: “Battery about 50%”

  • 31% - 40%: “Battery about 40%”

  • 21% - 30%: “Battery about 30%”

  • 11% - 20%: “Battery about 20%”

  • 1% - 10%: “Battery about 10%”

Built-in battery life (using a BLUETOOTH connection)

  • About 12 hours

    • The volume level of the neckband speaker is set to 16.

  • About 5 hours

    • The volume level of the neckband speaker is set to maximum (31).

Built-in battery life (after the built-in battery is charged for 10 minutes)

10 minutes of charging provide approximately 60 minutes of music playback. (Provided that the volume level of the neckband speaker is set to 16.)


The built-in battery life above is measured using our specified music source.

Actual performance time may vary from the listed time due to the volume, songs played, surrounding temperature, and usage conditions.

When the built-in battery is running low

When you hear voice guidance (Low Battery, Please Recharge Speaker) and the indicator starts flashing slowly in orange, the rechargeable built-in battery is running low. Charge the neckband speaker ahead of time.

When the rechargeable built-in battery has run out of power, you hear a notification sound and voice guidance (Please Recharge Speaker. Power Off.) and the neckband speaker automatically turns off. 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.

  • 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 supplied USB Type-C cable 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 sufficiently 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.

  • When the Android smartphone or the iPhone is configured to establish BLUETOOTH connections solely for music playback (A2DP) in multipoint connection, the remaining built-in battery power of the neckband speaker is not correctly displayed on the Android smartphone or the iPhone.
