Function issue

Please open the Nothing X app and go to: Device Settings > Standby ANC, then adjust the duration before the headphones enter standby mode.
Default setting: After 1 hour of inactivity, the device enters standby mode (ANC will be switched off).

To deliver longer battery life and a lightweight wearing experience, this product does not support wear detection. Playback must be paused manually when the headphones are removed.

2) The Nothing X app must be updated to the latest version via the Google Play Store.
3) The ChatGPT app must be downloaded, installed, and logged into from the Google Play Store, and the ChatGPT Voice feature must be used at least once.
4) In the Nothing X app, go to Controls, then assign ChatGPT to either the Single Press or Press & Hold gesture and apply the setting.

Please verify that all the above conditions are satisfied. If the issue persists, contact Nothing Support for further assistance.

1. Please check that the watch is worn correctly and adjust the strap tightness promptly.
2. On the watch, press the function button: Settings > Vibration, or on the dial interface, pull down the status bar >Settings> Vibration to modify the vibration level.
3. In the Nothing X app> My Devices page> About> Firmware Update, upgrade the firmware to the latest version for an experience.

1. Go to the watch's settings.
2. Navigate to "Sounds"
3. Select "Volume"
4. Adjust the ringer volume for incoming calls to your desired level.

The detection and recognition of the Type-C audio cable takes about 5 seconds. To avoid a poor experience caused by a detection failure—which would delay Bluetooth reconnection by over 8 seconds—the headphones prioritise Bluetooth reconnection first. If you want to use USB Audio, please try unplugging and plugging the Type-C audio cable again after powering on.

The Nothing headphone (1) uses a three-segment 3.5mm jack that does not support microphone input, so MIC calls are not available via the Aux-In connection.

1. When using the USB-C audio cable, you can adjust the volume either by the headphones’s roller or by the volume controls on the connected device.
2. When using the 3.5mm Aux-In audio cable, volume cannot be adjusted using the headphones’ roller and can only be controlled via the connected device’s volume buttons. Rest assured that this design is consistent with other brands of over-ear headphones and is not a malfunction.

1. When using the Tyep-C audio cable, you can listen to music and make phone calls normally.
2. When using the 3.5mm Aux-In audio cable, you can only listen to music. Please note that this product uses a three-segment 3.5mm Aux-In which does not support microphone input.

CMF Buds 2a supports active noise cancellation (ANC) up to 42dB. We recommend downloading the Nothing X app and checking the ANC settings under Noise Control. This setting offers multiple options such as High, Mid, Low and Adaptive.

Improper fitting of the ear tips can affect the noise cancellation seal, resulting in poor or ineffective noise cancellation. The earbuds come with different sizes of ear tips. We suggest trying different ear tips to find the best fit for optimal noise cancellation.

For more precise adjustments and settings, please use the Nothing X app, available on Google Play and the iOS App Store.

Everyone hears differently. With Personal Sound, your audio is tailored to your unique hearing characteristics, ensuring the best possible listening experience.

This feature consists of two key components: hearing test and hearing compensation.
1. Hearing test: an accurate hearing assessment helps determine your ability to perceive sounds at different frequencies. Audiodo Personal Sound complies with the ISO 389 standard, guaranteeing reliable and precise performance in hearing-related applications.
2. Hearing compensation: based on your test results, the system fine-tunes the EQ, dynamically adjusting frequencies to match your hearing profile. Audiodo analyses the content's frequency spectrum in real time, ensuring an optimised listening experience.

How it works:
1. Activate Personal Sound Profile in the Nothing X app.
2. Complete a quick, real-time hearing test (approximately 3 minutes) to generate your unique sound profile, which is then stored on your earbuds.
3. The algorithm continuously detects the music signal and dynamically adjusts the sound, ensuring a consistently hi-fi listening experience tailored to you.

If you encounter this issue, please check the following:

1. Ensure the Smart Dial's Rotate control is correctly set in the Nothing X app under CONTROLS.
2. Verify that your phone is set to synchronize Bluetooth volume with the phone volume (Bluetooth absolute volume). If not enabled, please turn it on in the phone's Bluetooth settings or developer settings.
3. Check if your earbuds are already at the maximum or minimum volume. Try rotating the dial in the opposite direction to see if there is any feedback.

1. When the charging case battery is at 1%, the case will shut down, causing the button to become unresponsive. This is not an earbud malfunction. If you experience a low battery shutdown, please connect the charging case to a power source with the lid closed to recharge it.

2. In areas with significant environmental interference (such as numerous signal transmitters/receivers or other interference factors caused by weather), the earbuds and charging case may occasionally disconnect. Please check for environmental interference factors. You can open and close the charging case lid to reconnect the earbuds.
*Reconnection takes approximately 3-4 seconds.

3. double tap & hold function:
To reduce accidental touches in certain scenarios, the product design includes a double tap & hold function to temporarily disable the charging case button. If you accidentally disable the button, use the Smart Dial on the charging case to perform double tap & hold, or place both earbuds back in the charging case, close and reopen the lid to restart the charging case Smart Dial function.
*This feature can only be used if the charging case Smart Dial function is set in the app.

Some apps do not support these type of commands. Is so, they will not respond to the press control commands on Ear (2), resulting in an invalid gesture control. This problem is not caused by Ear (2) itself.
If you have any further concerns, please contact Nothing Customer Serivce.

Some phones or computers may not support the volume adjustment protocol. If you encounter this problem, please connect Ear (2) with a commonly used device and try to adjust the volume. If there is no issue with more common devices, it is a compatibility issue with a specific device.
If you have any further concerns, please contact Nothing Customer Service.

1. Try to press the correct corresponding area again.
2. Place the earbuds into the charging case, close it, and open it. Then wear the earbuds to test again.

The delay on the phone volume display is caused by Bluetooth compatibility. Please refer to the earbuds' volume.

1. Try different apps to confirm if the problem is with the specific app on your chosen device.
2. Ensure that your device media volume is not low or muted.
