  • Which speakers can be connected in Party Mode?

    Nothing, CMF brand speakers and some headphones, as well as most other brands' devices that support Auracast™ technology.

  • What is the speaker’s Party Mode and how to use it?

    Powered by Auracast™, connect two or more speakers wirelessly to create a wider soundstage and a more immersive listening experience.

    With Party Mode, everyone can easily join the same listening experience without worrying about who connects to the speaker. Simply bring your own speaker, turn on Auracast™, and join the party.

    Whether you’re hanging out with friends, camping outdoors, or hosting a party at home, sync multiple speakers to spread music across the space and create a more immersive, shared listening experience for everyone.

  • What is the speaker’s Stereo Mode and how to use it?

    2 identical speakers can be set up as separate left and right channels via Stereo Mode.
    This creates a broader soundstage and more accurate positioning compared to a single speaker, making it suitable for desktop audio and delivering enhanced immersion for music, films, and games.
    * Need to purchase an additional speaker of the same model to enable this function.
    * Open the Nothing X App, follow the instruction to activate Stereo Mode to pair the speakers.
    * In Stereo Mode, all controls and sound settings (playback, volume, EQ, Wide Soundstage Mode) sync across both speakers.

  • What is the speaker’s Night Mode and how to use it?

    Night Mode caps volume at 60% and reduces deep bass for quieter listening, so you get a quiet, comfortable sound that won't disturb your sleep.

  • What is the speaker’s Auto Wake‑Up?

    With external power connected, the speaker after 30 minutes of no music and control will enter a standby mode instead of powering off.
    Once the paired device initiates reconnection from device within effective Bluetooth range.
    The speaker wakes automatically, no manual power‑on or re‑pairing required.

  • How do I put the CMF Speaker into pairing mode?

    When the speaker is powered on, long‑press the Bluetooth pairing button for 2 seconds. The device enters pairing mode once the back indicator light flashes blue slowly.

  • When the CMF Speaker is connected to two devices, which device's audio will be played?

    1. When the speaker is connected to two idle devices:
    Audio output follows the device that initiates music playback first.

    2. When the speaker connects to two devices and only one is playing music:
    Music starts on the non‑playing device Audio channel will not switch. Both devices stay in playback state, with the newly‑playing device muted.

  • When the CMF Speaker is connected to two devices, which device will be controlled by the button functions?

    Button controls apply to whichever mobile phone the CMF Speaker is currently outputting audio from. When no audio is playing, the controls target the most‑recently connected device or the last device that played audio through the speaker.

  • How does the dual connection logic work on the CMF Speaker?

    Automatic reconnection on power on / exit from sleep mode:
    1. When dual‑connection is enabled and the speaker powers on with no USB‑C audio cable plugged in:
    If fewer than two devices are connected, the speaker will attempt to reconnect to its last‑two paired devices.
    If dual‑connection is enabled for the first time with no prior connection records, the speaker maintains a single‑device connection.
    (In single‑connection mode, the speaker will not auto‑enter pairing mode. To pair a new device, users must manually long‑press the Bluetooth pairing button.)
    If reconnection to other devices fails, the speaker remains connected to one device and will not enter pairing mode.
    2. If the speaker and connected devices move out‑of‑range and then return within range, the speaker will only reconnect to the device disconnected due to distance.
    3. Reconnection will not be triggered when the speaker is in music playback state.

    Connection snatch:
    In dual-connection mode, new devices cannot snatch existing connections. To connect a third device, disconnect one of the currently connected devices first.

    Tips:
    Music state rules
    1. If one of the two connected phones is playing music, the speaker will disconnect the non‑playing phone and connect to the snatch‑initiating device.
    2. If both connected phones are playing music, the speaker will drop the phone whose audio is not outputting to the speaker (the muted playback device) and connect to the snatch‑initiating device.
