  • Why are my headphones shown as “speakers” on Windows?

    The “Speaker” mode allows the JBL QuantumENGINE to receive more than two channels of audio. It also prevents some applications from adding extra signal processing intended for other headphones, which would negatively impact the performance of the JBL QuantumSURROUND or JBL QuantumSPHERE 360 technology.

  • Why do I need to use the calibration microphone included with my JBL Quantum ONE?
    We believe the baseline performance of the QuantumSPHERE technology is cutting edge in terms of localization. The calibration feature improves upon this performance by calibrating the system to your individual anatomy.
  • Why is there no USB-C PD Adaptor included with my speaker?

    To minimize e-waster, we consciously choose not to include a USB-C PD Adaptor in our speaker packaging.

    You can purchase the dedicated 15-60W JBL USB-C PD adaptor on jbl.com or any other retail stores. Simply connect the USB-C PD Adaptor with your speaker and enjoy the guaranteed performance JBL promised.

  • Wi-Fi vs. Bluetooth streaming
    Using Wi-Fi allows you to listen to your music in a higher sound quality since Bluetooth protocol compresses the audio signal, where Wi-Fi data easily stream HD Audio content. Take calls without interrupting your current audio music, where Bluetooth will interrupt the stream, because it is a one-way protocol. Control your music from anywhere in the house, where Bluetooth have a limited range. Play the same music across multiple speakers and when using the newest connect features, such as Spotify Connect or Chromecast built-in, then you don't have to worry about battery life, since the devices playing is doing all the data transmission compared to Bluetooth, where it is data between source and device.
  • Will Control Xstream switch off when they are not used (standby)
