Maintenance and Care
Cleaning
Regularly clean your earbuds and charging case to ensure optimal performance and hygiene. Use a soft, dry, lint-free cloth to wipe the surfaces. For the ear tips, remove them and clean with a mild soap solution if necessary, then rinse thoroughly and dry completely before reattaching. Do not use harsh chemicals or abrasive materials.
Water Resistance (IPX5)
The pTron Zenbuds Ultima are rated IPX5 water-resistant, meaning they can withstand splashes of water and sweat. This makes them suitable for workouts and light rain. However, they are not designed for submersion in water or for use during swimming. Ensure the earbuds are dry before placing them back into the charging case.

Battery Care
To prolong battery life, avoid exposing the earbuds and case to extreme temperatures. Store them in a cool, dry place when not in use. It is recommended to fully charge the device at least once every three months if not used regularly.
Troubleshooting
If you encounter issues with your pTron Zenbuds Ultima, please refer to the following common solutions:
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close the lid, wait a few seconds, then open the lid to re-enter pairing mode. On your device, forget the previous Bluetooth connection and try pairing again.
- Only one earbud working: Check if both earbuds are charged. Try placing both earbuds back into the charging case, close the lid, and then take them out simultaneously. This often re-syncs them.
- No sound: Check the volume level on your device and the earbuds. Ensure the earbuds are properly connected to your device. Try playing audio from a different application or source.
- Charging issues: Ensure the charging cable is securely connected to both the case and the power adapter. Use a DC5V-1A charger. Clean the charging contacts on the earbuds and inside the case with a dry cotton swab.
- Poor call quality: Ensure the microphones are not obstructed. Try moving to an area with less background noise.
- Intermittent connection: Ensure your device is within the 10-meter Bluetooth range. Avoid obstacles between the earbuds and your device.
