If your Micro II does not sense an audio signal on its input, it goes into Standby to save power. It should wake up again when audio is sensed. Since Micro II senses audio on its input, not on the speaker volume, always turn up the volume on the source, then control speaker volume on the Micro II. This way it will not go into Standby unless music stops.

When not connected to AC power, the speaker will be automatically switch off after 1 hour of inactivity to save battery consumption. You can adjust the auto standby time on JBL One app.

The speaker has an auto calibration feature, which measures the space around the speaker and adjusts the sound quality based on the room around it. Auto calibration will automatically work when you power on the speaker and begin playing music. For the best sound, we recommend placing the speaker in the middle of the room, at least 0.5 meters away from any walls.

There is a setting in the JBL One app called Bluetooth reconnection. You can change the behavior to enable it to automatically reconnect every time the speaker is turned on, if this is the behavior you want.

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.

If the preset DAB/FM station signal is not strong enough the alarm will go off in buzzer mode instead. Make sure the signal is strong enough, by checking that the station plays without static or distortion (FM).

To minimize e-waste, we consciously choose not to include a charging cable in our packaging.

You can use any standard USB-C cable to charge your JBL product as well as a power adapter compliant with the USB-C standard.

Past product already have standardized USB-C cables, which can be reused for new products.

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.

In the ANC on mode, we take advantage of advanced signal processing to finely tune, and personalize the audio performance. In passive and in ANC off mode, that signal processing is not running, so you may hear a difference in audio performance

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.

This speaker will go to standby mode after 10 minutes inactivity. It turn on when you start playing to it again.

Only if you have pressed the button on the remote or Boost TV itself.

Yes, when casting music to your JBL Playlist, your speaker is connected to Google Cloud, which will turn your smart device into a remote control, rather than streaming music directly to the Playlist.

Yes, if no audio is present and no buttons are pressed, DUET will go into standby after approx. 10 minutes.

The head tracking will only work when connected via the wireless USB (A or C) dongle. The reason for this is that the head tracking technology uses a lot of processing power and a low latency connection.

When connected to a device using the Wireless USB (A or C) dongle the head tracking feature (JBL QuantumSPATIAL 360) will work. To enable JBL Quantum 360SPHERE and spatial calibration the JBL Quantum Engine is required.

There is no plan for adding JBL Connect support for Playlist speaker. But you can group any speaker together that support Chromecast built-in for multi-room experience.
