3. Operating Instructions
Basic Functions
The headphones feature multi-function touch controls on each earbud.
- Play/Pause Music: Single tap on either the Left (L) or Right (R) earbud.
- Answer/End Call: Single tap on either the Left (L) or Right (R) earbud.
- Next Song: Double tap on the Right (R) earbud.
- Previous Song: Double tap on the Left (L) earbud.
- Volume Up: Triple tap on the Right (R) earbud.
- Volume Down: Triple tap on the Left (L) earbud.
- Activate Voice Assistant: Press and hold either (L) or (R) earbud for 1 second.
- Power Off Headphones: Long press either (L) or (R) earbud.
Stereo/Mono Mode
The headphones support both stereo and mono modes. In mono mode, each earbud can be used independently and connected to different devices simultaneously. This allows you to listen to music on one earbud while taking calls on the other, or share one earbud with another person.
- Stereo Mode: Both earbuds are connected to the same device, providing a full stereo sound experience. This is the default mode when both earbuds are removed from the case.
- Mono Mode: Remove only one earbud from the charging case. It will automatically connect as a single earbud. To connect each earbud to a different device, ensure they are not paired to the same device first, then pair each individually.
Voice Control
Activate your device's voice assistant (e.g., Siri, Google Assistant) by pressing and holding the multi-function button on either earbud for 1 second. You can then use voice commands for tasks such as checking the weather, making calls, or controlling music playback.
4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your headphones.
- Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Eartips: Remove and clean the eartips periodically. They can be gently washed with water and mild soap, then thoroughly dried before reattaching.
- Storage: When not in use, store the headphones in their charging case to protect them from dust and damage.
- Water Resistance: The headphones are sweat-resistant, making them suitable for sports. However, they are not waterproof. Avoid submerging them in water or exposing them to heavy rain.
- Temperature: Avoid exposing the headphones to extreme temperatures (hot or cold) or high humidity.
5. Troubleshooting
If you encounter issues with your headphones, refer to the following common solutions:
