Maintenance
Water Resistance (IPX7)
The earbuds are rated IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for use during workouts, in light rain, or when exposed to sweat. However, they are not designed for swimming or prolonged submersion.
- Do not expose the charging case to water, as it is not waterproof.
- After exposure to water or sweat, ensure the earbuds are completely dry before placing them back into the charging case to prevent damage to the charging contacts.

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.
- Gently clean the charging contacts on both the earbuds and inside the case with a dry cotton swab to ensure proper charging.
- Avoid using abrasive materials, alcohol, or chemical cleaners.
Troubleshooting
If you encounter any issues with your BESNOOW TX90 Wireless Earbuds, please refer to the following common solutions:
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close it, then open it again to re-initiate pairing mode. Check your device's Bluetooth settings and try reconnecting.
- Only one earbud working: Place both earbuds back in the charging case, close the lid, and then open it again. This should reset the connection between them. If the issue persists, try unpairing from your device and re-pairing both earbuds.
- No sound or low volume: Check the volume levels on both your device and the earbuds. Ensure the earbuds are properly seated in your ears. Try cleaning the speaker mesh if it appears obstructed.
- Charging issues: Ensure the charging cable is securely connected to both the case and the power source. Clean the charging contacts on the earbuds and inside the case. Try a different charging cable or power adapter.
- Unstable connection: Ensure there are no significant obstacles between your device and the earbuds. Keep the earbuds within the recommended Bluetooth range (typically 10 meters). Avoid strong electromagnetic interference.
If these steps do not resolve your issue, please contact BESNOOW customer support for further assistance.
