The charging time for the INZONE H9 II is too long

    This article provides essential guidelines and troubleshooting steps to ensure optimal performance when charging your headphones.

    Check the following steps:

    • When charging with a computer, ensure that the headphones and computer are directly connected, without using a USB hub.
    • Check that you are using the supplied USB Type-C® cable.
    • 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 issue is still not resolved:

    • Restart your computer or PlayStation®5, and reconnect the USB cable.
    • If the issue continues after restarting the computer or PS5™ and reconnecting the USB cable, charge your headphones by plugging them into an AC outlet.
