2.1 Choosing the Right Ear Tips and Ear Hooks

For optimal sound quality and comfort, select the ear tips and ear hooks that best fit your ears. Experiment with the different sizes (S/M/L ear pads) and styles of ear hooks provided.

• Ear Tips: Gently pull off the pre-installed ear tips. Select a size that creates a good seal in your ear canal without causing discomfort. Push the new ear tip firmly onto the earphone nozzle.
• Ear Hooks: The ear hooks provide additional stability, especially during physical activity. Choose a hook style that comfortably secures the earphone in your outer ear. Attach the ear hook to the designated slot on the earphone body.

• Cleaning Earphones: Wipe the earphone bodies and cable with a dry, soft cloth. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, store the earphones in a clean, dry place, preferably in a small pouch or case to prevent tangling and damage to the wires.
• Avoid Extreme Conditions: Do not expose the earphones to extreme temperatures, humidity, or direct sunlight.
• Handle with Care: While the wires are designed to be fold-resistant, avoid excessive bending or pulling on the cable, especially near the connectors.

5. Troubleshooting

If you encounter any issues with your earphones, please refer to the following common solutions:

• No Sound:
  • Ensure the 3.5mm jack is fully inserted into your device's audio port.
  • Check the volume level on your device and using the inline remote.
  • Test the earphones with another device to rule out a device-specific issue.
  • Ensure the audio output is directed to the headphone jack on your device settings.
• Poor Sound Quality (Distortion, Low Volume):
  • Ensure the ear tips are properly sealed in your ear canal. Try different sized ear tips.
  • Clean any debris from the earphone nozzles and ear tips.
  • Check if the audio source is of good quality.
• Microphone Not Working:
  • Ensure the 3.5mm jack is fully inserted. Some devices require a TRRS (4-pole) jack for microphone functionality, which these earphones provide.
  • Check your device's audio input settings to ensure the external microphone is selected.
  • Test the microphone with another application or device.
• Earphones Keep Falling Out:
  • Experiment with different ear tip sizes and ear hook styles to find the most secure fit for your ears.
