Bluetooth connection issue

The NFC feature is designed to help your phone quickly recognize and pair with the speaker. Once the speaker is connected and playing audio, there is no need to tap the NFC area again.
Tapping the NFC area during active playback may cause your phone to re-initiate the device recognition or pairing process. This can result in brief audio stuttering, interruptions, or on some phones, a complete Bluetooth disconnection. (Note: The NFC feature is not designed to disconnect the speaker.)
How to Recover & Tips:
Reconnect: If the Bluetooth connection drops, please go to your phone's Bluetooth settings and manually select the speaker to reconnect.
Resume Playback: Once successfully reconnected, simply resume your audio playback.
Usage Tip: To ensure a smooth experience, please avoid placing your phone near or tapping the speaker's NFC area while music is playing.

Due to platform-related behavior on iOS, this issue can sometimes occur. Please try the following steps to resolve it:
1. Open the Settings on your iPhone and go to the Bluetooth menu. If the speaker appears in the list of previously connected devices, tap the “i” icon next to it, then select “Forget This Device.”
2. Follow the pairing process again and connect to Bluetooth, then re-open the Nothing X app to search and connect again.

1. Device discovery is an interactive process between the phone and the speaker. Sometimes, the phone may experience a Bluetooth logic issue that prevents it from finding the speaker. This is not a speaker malfunction. You can try turning Bluetooth off and back on, or restart your device and search again.
2. If the issue persists, press and hold the Bluetooth pairing button for more than 10 seconds to perform a factory reset. Alternatively, restart the speaker using the power key, and try a forced reboot by holding the Bluetooth pairing button while plugging and unplugging the USB Type-C cable, then try pairing again.

When connecting the speaker with an iOS phone, please first pair the speaker via your phone's Bluetooth settings, then open the Nothing X app to connect. Please note that this product does not support CTKD (Continued Tracking of Key Distribution).

In Dual-Connection, Stereo Mode, or Party mode, the speaker requires a brief moment to complete device connection and audio channel switching. If audio is played before the connection is fully established, you may experience a slight delay or brief silence. Playback will return to normal once the connection stabilizes.
This is related to Bluetooth compatibility and connection timing across different devices. It is normal behavior and not a hardware defect, so please rest assured.
Tips for a better experience:
Wait for Connection: Allow the connection to fully establish before playing audio.
Manage Background Apps: During Dual-Connection mode, pause or close background media applications (music, video, etc.) on any connected device that is not currently in use.

When the Bluetooth connection is lost due to distance, the speaker will automatically disconnect.
If you return within 10 minutes, the speaker will reconnect automatically.
If it takes longer than 10 minutes, the speaker will enter a timeout state and will not reconnect automatically.
You can try the following steps:
1. Manually tap to reconnect the speaker from your device’s Bluetooth settings,
or toggle the power switch off and then on to reinitiate the connection.
2. Press and hold the multifunction button for 10 seconds or more to restore factory settings, then re-pair the speaker.
3. If the issue persists, please download and update to the latest firmware using the Nothing X App and try again.

1. When the speaker has connection records for multiple devices, it will preferentially reconnect to the last‑connected device upon power‑on. Please check whether the last device used with the speaker is your current active device.
2. After the speaker powers on or exits Sleep mode, the reconnection timeout period is 10 minutes. Once timed out, the speaker enters a connectable but undiscoverable state. You will need to long‑press the Bluetooth Button until the back White LED flashes, then search and connect from your device.
3. Long‑press the Bluetooth pairing key for 10 seconds or longer to perform a factory reset, then re‑pair the speaker for use.
4. If the above steps fail to resolve your issue, download and install the latest firmware via the Nothing X App and try again.

For a better user experience, when the headphones are in dual connection mode and disconnect due to exceeding the connection range, they will only automatically reconnect to the second device after returning to range if the headphones are not currently in a music, call, or meeting state. If they are in any of these states, they will not reconnect to the second device automatically. This behavior is normal and not a malfunction of the headphones. Please rest assured when using them.

When using an iOS device, the app connects to the headphones via the BLE (Bluetooth Low Energy) protocol. During a phone call, the system prioritizes the call and allocates most of its processing power and communication bandwidth to it. As a result, BLE communication is temporarily suspended, and the app cannot connect to the headphones at that time. This is normal behavior and not a fault.

1. When the headphones have a connection history with multiple devices, they will prioritize reconnecting to the last connected device upon startup. Please confirm whether the device you are currently using was the last one connected to the headphones.
2. After powering on or exiting sleep mode, the headphones will attempt to reconnect for 1 minute. If reconnection is unsuccessful, they will enter pairing mode for 2 minutes. During this time, we recommend re-searching for the headphones on your device and connecting manually.
If not connected within 2 minutes, the headphones will enter an unconnected state and require a manual press of the Bluetooth pairing button until the white LED starts flashing to enter pairing mode.
3. Please check if a USB-C Audio or 3.5mm cable is inserted. When a wired connection is detected, it will take priority, and the Bluetooth connection will be automatically disconnected. Once the cable is removed, the headphones will automatically trigger Bluetooth reconnection.
4. Press and hold the Bluetooth pairing button for 10 seconds or more to restore the headphones to factory settings, then re-pair them.
5. If the issue persists, please download and update to the latest firmware using the Nothing X App and try again.

All device customizations are already integrated into the Settings of Nothing OS version 1.1.4 and higher. Please keep the Nothing X app updated in the Google Play Store.

Audio output is controlled by your Mac. Since the device does not send a new SCO connection switch request, meeting audio continues to play through the earbuds. We have verified that this occurs with all similar earbuds connected to Mac.

1. Since device searching is an interactive process between a mobile phone and Earbuds, there may be a Bluetooth logic issue on the mobile phone side, which prevents the Earbuds from being detected. This phenomenon is not a problem with the Earbuds. You can try turning off and then turning on the mobile phone's Bluetooth, or restarting the terminal device and trying to search again.
2. If the problem persists, you can place both Earbuds in the charging case, close the lid, and wait for more than 30 seconds to perform a hard restart on the Earbuds. Alternatively, you can place the Earbuds in the case and open the lid, then press and hold the function button for more than 10 seconds to restore the Earbuds to their factory settings before trying again.

1. When the Earbuds have established connection records with multiple devices, they will prioritize reconnecting to the last device they were connected to the previous time when turned on again. Please confirm whether the device you used the Earbuds with for the last time is the one you are currently using.
2. After the Earbuds are taken out of the charging case, if they fail to find the last connected device within one minute, they will enter a connection timeout state. You need to put the Earbuds back into the case, close the lid for 5 seconds, and then open the lid to initiate the connection again.
3. Press and hold the pairing button for 10 seconds or more to restore the Earbuds to factory settings, and then re-pair them for use.

For the sake of user experience, when the product is in a dual-connection state, if a disconnection occurs due to being out of range, and then you return to the connection range while your Earbuds are in a music playback, call, or meeting state, the Earbuds will not automatically reconnect to the second device. This is not an abnormality of the Earbuds, so you can use them with confidence.

1. When the charging case is low on power, it cannot charge the Earbuds. However, the Earbuds can still reconnect to it. It is recommended to wait 2 seconds after closing the case lid before opening it again.
2. When the charging case has an extremely low battery, it can neither charge the Earbuds nor allow them to reconnect. It will function normally once it is charged.
We strongly recommend that you connect the charging case to a power source to charge it as soon as possible when it is low on power.

Due to the iOS platform-related reasons, when this issue occurs, please try to restore it by following the steps below:
1. Open the Settings app on your phone, go to the Bluetooth interface, and check if the Earbuds device is among the connected devices. If it is, tap the "i" button next to the Earbuds and then select "Forget This Device".
2. Re-enter the Nothing X App and re-perform the pairing and connection process.

We apologise for any inconvenience caused. Please note the following regarding this behaviour: Some computers or online meeting applications may repeatedly attempt to reclaim the audio channel after it is interrupted by a phone call. This behaviour is related to system or application compatibility.

To resolve this:
1. Set the online meeting app to use a non-Bluetooth audio channel where possible.

2. After ending the phone call, if meeting audio does not resume, manually reselect the Bluetooth AG audio channel in the meeting app. Alternatively, power the headphones off and on to trigger automatic Bluetooth reconnection.

To ensure simple and reliable audio output switching, the headphones automatically disconnect Bluetooth wireless audio once a wired audio connection is detected. This is by design. If you want to use Bluetooth audio, please unplug the wired audio cable.

When in Dual Connection and disconnected due to exceeding the connection range, CMF Headphone Pro will only automatically reconnect to the second device after returning to range if the headphones are not currently in a music, call, or meeting state. If it is in any of these states, it will not reconnect to the second device automatically.

Due to compatibility issues, certain computers or online meeting platforms may repeatedly attempt to take over the audio connection, causing your sound to default back to the online meeting.

To resolve this:

1. Configure the online meeting app to use a non-Bluetooth audio channel.
2. Manually reselect the Bluetooth AG channel in the meeting software.
3. Alternatively, toggle the headphone’s power switch off and on to trigger automatic Bluetooth reconnection. This will help re-establish the correct audio output channel for the network meeting.

Please try the following steps to resolve the issue:

1. Open the Settings app on your iPhone and go to the Bluetooth menu.
2. If the headphone device appears in the list of previously connected devices, tap the 'i' icon next to it, then select Forget This Device.
3. Reopen the Nothing X app and follow the pairing process again.
