  • Why does my headphones only reconnect to one device after walking away and coming back, even though it was connected to two devices with dual connection?
    For a better user experience, when the headphones are in dual connection mode and disconnects due to exceeding the connection range, it 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. Rest assured that this behavior is normal and not a malfunction.
  • I've connected my headphones to both my phone and laptop, and am using the headphones for online meetings on my laptop. Why does the phone call audio come from the phone when I receive a call?
    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 utilise a non-Bluetooth audio channel. 2. Should the headphones fail to relay audio from the online meeting, manually reselect the Bluetooth AG channel in the meeting software. 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.
  • Why can't my device find the headphones during pairing?
    1. Device discovery is an interactive process between the phone and the headphones. Sometimes, the phone may experience a Bluetooth logic issue that prevents it from finding the headphones. This is not a headphone 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 headphones 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.
  • Why does it take a while for my headphones to output sound after connecting to a device?
    Due to compatibility issues related to Bluetooth connection priority and dual connection functionality on some devices, a delay in audio output may occur during music channel switching or connection snatching in dual connection mode. This is a common issue that may affect over-ear Bluetooth headphones across the market. We recommend directly connecting the headphones to the device you want to use, and closing background audio apps on other connected devices. This is not a fault with the headphones—please feel assured in using them.
  • Why didn’t my headphones reconnect automatically after moving back into range?
    When the Bluetooth connection is lost due to distance, the headphones will automatically disconnect. If you return within 10 minutes, the headphones will reconnect automatically. If it takes longer than 10 minutes, the headphones will enter a timeout state and will not reconnect automatically. You can try the following steps: 1. Manually tap to reconnect the headphones 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 headphones. 3. If the issue persists, please download and update to the latest firmware using the Nothing X App and try again.
  • Why didn't the headphones automatically reconnect to my device?
    1. When the headphones have a connection history with multiple devices, they will prioritise 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 customisations 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.

  • Why don't the earbuds automatically reconnect to my phone when the charging case is low on battery?
