4.3. Single and Binaural Mode
The earbuds support both single and binaural modes. If you wish to use only one earbud, simply take one out of the charging case. The other earbud can remain in the case or be turned off. To use both, take both earbuds out of the case, and they will automatically connect to each other and your device.
5. Maintenance and Care
The Caymuller DT16 earbuds are IPX5 waterproof, protecting them from water splashes and sweat. This makes them suitable for workouts and outdoor activities. However, they are not designed for submersion in water.
To maintain optimal performance and hygiene:
- Regularly clean the earbuds and charging contacts with a soft, dry cloth.
- Ensure the charging case is dry before placing the earbuds inside.
- Store the earbuds and case in a cool, dry place away from extreme temperatures.
- Avoid using abrasive cleaners or harsh chemicals.
6. Troubleshooting
- Earbuds not pairing with each other or device: Ensure both earbuds are fully charged. Place them back in the charging case, close the lid, then open it again and remove them. Re-attempt the pairing process as described in Section 3.2.
- Only one earbud working: Check if the non-working earbud is charged. Place both earbuds back in the case, then remove them simultaneously to ensure they connect in binaural mode.
- Charging case not charging: Verify the USB cable is securely connected to both the case and a power source. Check if the power source is active.
- Poor sound quality: Ensure the ear caps are properly fitted and form a good seal in your ear. Clean any debris from the earbud speakers. Check your device's volume settings.
- Earbuds falling out: Experiment with different sizes of ear caps to find the most secure fit. Adjust the ear hooks to comfortably and firmly grip your ear.
