Please follow the below steps to resolve the issue on your iOS device:
1. Open the "Settings" on the iPhone.
2. Tap on "Bluetooth."
3. Find the earphones you want to forget in the list of devices.
4. Tap the "i" icon next to the earphones.
5. Tap "Forget This Device."
6. Confirm the action by tapping "Forget Device" in the pop-up.
7. Open the Nothing X App to pair the earphones again.

Due to compatibility issues with Bluetooth Fast Pair and Dual Connection features of some device systems, there may be occasional delays in sound output when you switch music channels or try to connect your device. The issue may occur with TWS Bluetooth earbuds on the market. This is a normal phenomenon and does not indicate any abnormality with the earbuds. Please feel free to use them with confidence.

Please make sure you are pressing the correct control area on the earbuds. If still unable to trigger the function, try switching to a different music app to see if the function works properly. When the gesture function is triggered, it sends commands through to the app for processing. But because some apps don't support switching commands, they will not respond to the earbuds' control commands, leading to ineffective gesture control.
This issue could potentially affect TWS Bluetooth earphones, but it doesn't indicate a problem with the earbuds themselves.

Due to compatibility issues with Bluetooth protocol versions of devices, some phone or computer models may not support the volume control protocol. This issue could potentially affect TWS Bluetooth earbuds. If you encounter this issue, try connecting the earbuds to another commonly used device to adjust the volume. If the issue doesn't persist, it means the device, not Nothing Ear, needs checking.

1. Continuously charge the device for 2 hours and check again
2. Replace the cable and charger
3. Charge the earbuds in a comfortable temperature environment (around 25°C) and try again

If the issue remains unresolved, please contact our customer service.

1. Check if there is dirt inside the charging port of the case
2. Use another cable or charger to see if it works fine
3. Plug in and plug out the charger several times to check if it works fine
4. Charge the earbuds in a comfortable temperature environment (around 25°C) and try again
If the issue remains unresolved, please contact our customer service

1. Check if there is any dirt inside the charging pin of the earbuds and the pogo pin on the charging case.
2. Gently shake the charging case to ensure that the earbud charging pins and the pogo pins on the charging case make full contact, then check if charging works.
3. Place the earbuds in the charging case and connect to the charger for 10 minutes in a comfortable temperature environment (around 25℃) to see if it recovers.
4. Open the case, long-press the pair button for 10 seconds, wait until the indicator LED is on, and try again.

1. When connected to multiple devices, the earbuds will prioritise reconnecting with the last device connected upon powering on again. Please confirm if the last device used is the one you are currently using.
2. If the earbuds leave the charging case and don't find the last connected device within 1 minute, they will enter a timeout state. To exit it, place the earbuds back into the case, close the lid for 5 seconds and then reopen to initiate a new connection.
3. Perform a factory reset by holding the function button on the charging case for 10 seconds or more, and then pair the earbuds again.
4. If the issue remains unresolved, please download and update to the latest software using the Nothing X App.

Note: 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 via the Google Play Store.

The sound quality of Ear (a) is tuned based on extensive user experiences and is at a relatively high industry standard. However, individual preferences for sound quality may vary. We recommend downloading the Nothing X App and accessing the Equaliser function to choose preset sound effects. Additionally, you can customise the sound according to your personal preferences in the Custom settings.

1. Since Bluetooth device searching is an interactive process between a phone and a pair of earbuds, the phone side may have Bluetooth logic issues that hinder the search for Ear (a). This phenomenon is not an issue with the earbuds. You can try turning the phone's Bluetooth off and then on again, or restart the device and try searching again.
2. If the problem persists, place both earbuds in the charging case, close the lid, and wait for more than 30 seconds to allow the earbuds to reboot, or place them in the case and open the lid, then long-press the function key for more than 10 seconds to restore to factory settings before trying again.

This is normal. When connected to an iOS device, the Bluetooth connection through the app uses the BLE (Bluetooth Low Energy) protocol. The earbuds and the app establish a connection via low-power Bluetooth. During a call, the system prioritises processing power and communication bandwidth for the call as priority. Consequently, the communication over low-power Bluetooth is halted.

Please make sure you are pressing the correct control area on the earbuds. If still unable to trigger the function, try switching to a different music app to see if the function works properly. When the gesture function is triggered, it sends commands through to the app for processing. But because some apps don't support switching commands, they will not respond to the earbuds' control commands, leading to ineffective gesture control.
This issue could potentially affect TWS Bluetooth earphones, but it doesn't indicate a problem with the earbuds themselves.

1. Power consumption varies depending on the scenario, with the highest power consumption happening during voice calls.
2. In actual usage, factors such as high volume, audio streaming codec, and environmental interference can impact battery life. We recommend lowering the volume and using the AAC mode to improve battery life.
- To set the AAC mode:
1) Connect the earbuds to your phone via Bluetooth, go to the Bluetooth settings, select Ear (a), enter the detailed Bluetooth device settings and choose HD (AAC) or directly enable AAC for Media audio.
2) After connecting the earbuds to your phone via Bluetooth, go to Developer options (accessible through Settings > Additional settings > Developer options), find Bluetooth Audio Codec and select AAC.
- Please note that the specific settings paths may vary depending on your phone's brand and model, so refer to the actual settings.
3. Please upgrade the Nothing X app to the latest version through the Google Play Store or the iOS App Store. In the app, navigate to Settings and select Firmware Update.
4. If the above suggestions still don't resolve your issue, place both earbuds into the charging case, open the case and long-press the function button on the charging case for 10 seconds to perform a factory reset. Then try again.

Ear (a) supports a maximum of 45 dB of noise cancellation. Please download the Nothing X App and access the ANC settings in the app's Noise Control section. Additionally, the effectiveness of noise cancellation is heavily influenced by how the earbuds are being worn. Incorrect positioning or ill-fitting ear tips can affect the airtight seal and, consequently, the noise cancellation performance. We recommend trying different ear tips and adjusting the fit to ensure a snug and leak-free seal for the best noise cancellation experience. If you have any other concerns, please contact our Customer Service.

1. The earbuds will automatically disconnect when the Bluetooth connection exceeds the range. If you return to the connection range within 10 minutes, they will automatically reconnect successfully. If they stay outside of the connection range for more than 10 minutes, they will enter a timeout state without a connection. You can manually reconnect by placing the earbuds into the charging case, closing the charging case for 5 seconds, and then opening the charging case to power on the earbuds and initiate the connection again.
2. Long-press the function button on the charging case for 5 seconds and reset to factory settings - complete when the indicator light flashes red for 10 seconds. Then re-pair for use.
3. If the issue remains unresolved, please download and upgrade to the latest version of the Nothing X App and try again.
