Maintenance

Cleaning

• Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
• Remove eartips and clean them with mild soap and water, then dry thoroughly before reattaching.
• Ensure charging contacts on both earbuds and case are clean and free of debris to maintain proper charging.

Storage

• When not in use, store the earbuds in their charging case to protect them and keep them charged.
• Avoid storing the device in extreme temperatures or high humidity.

Water Resistance

The Nequga T21 earbuds are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for workouts and use in light rain. However, the charging case is not waterproof. Do not expose the charging case to water.

Troubleshooting

If you encounter issues with your Nequga T21 earbuds, refer to the following common solutions:

• Earbuds not charging: Ensure the charging contacts on both the earbuds and the case are clean and dry. Verify the USB-C cable is properly connected and the power source is active.
• Pairing failures: Make sure Bluetooth is enabled on your device and the earbuds are in pairing mode (open the case lid). Try forgetting the device in your phone's Bluetooth settings and re-pairing. Ensure the earbuds are fully charged.
• No sound or low volume: Check the volume levels on both your connected device and the earbud/case touchscreen. Ensure earbuds are properly seated in your ears. Try re-pairing the earbuds.
• Call quality issues: Ensure the earbuds are fully charged. Check for obstructions between the earbuds and your device. If in a very noisy environment, ensure ENC is active.
• Charging case screen always on: The screen may activate with movement. Ensure it is locked or allowed to time out to conserve battery.
• Media not pausing when earbuds are removed: Some devices or apps may not automatically pause. Manually pause playback using the earbud touch controls or your device.
• Single earbud connection issues: If only one earbud connects, try placing both back in the case, closing the lid, then reopening. If the issue persists, try the "Find My Earphone" feature for the non-connecting earbud, then stop it, as this can sometimes re-establish connection.
