Touch Controls

The EW39 earphones utilize touch controls for various functions. Specific touch gestures (e.g., single tap, double tap, long press) will control playback, calls, and voice assistant activation. Refer to the quick start guide or product packaging for detailed touch control mapping.

  • Play/Pause: Typically a single tap on either earbud.
  • Next Track: Typically a double tap on the right earbud.
  • Previous Track: Typically a double tap on the left earbud.
  • Answer/End Call: Typically a single tap on either earbud.
  • Reject Call: Typically a long press on either earbud.
  • Activate Voice Assistant (Siri): Typically a triple tap or long press on either earbud.

Note: The EW39 does not feature physical control buttons or volume control directly on the earbuds. Volume adjustments must be made via your connected device.

Making and Receiving Calls

The earphones are equipped with single-mic ENC (Environmental Noise Cancellation) for clearer call quality by reducing background noise.

  • When a call comes in, tap either earbud once to answer.
  • To end a call, tap either earbud once.
  • To reject an incoming call, long-press either earbud.

Maintenance

  • Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials.
  • Storage: When not in use, store the earphones in their charging case to protect them and keep them charged.
  • Water Resistance: These earphones are NOT waterproof. Avoid exposure to water, moisture, rain, or sweat to prevent damage.
  • Temperature: Do not expose the earphones to extreme temperatures (hot or cold) as this can shorten battery life and affect performance.

Troubleshooting

  • Earphones not pairing: Ensure both earphones are in the charging case, then open the lid to activate pairing mode. Make sure Bluetooth is enabled on your device and select "HOCO EW39". If issues persist, try forgetting the device on your phone and re-pairing.
  • Only one earphone working: Place both earphones back into the charging case, close the lid, then open it again. This should reset the connection and allow both to connect. Ensure both earbuds are charged.
  • No sound: Check the volume level on your connected device. Ensure the earphones are properly paired and connected. Try playing audio from a different application or source.
  • Charging issues: Verify the charging cable is securely connected to both the case and the power source. Check the LED display for charging indicators. If the case or earbuds are not charging, try a different cable or power adapter.
  • Poor call quality: Ensure the earbuds are properly seated in your ears. Move closer to your connected device to improve signal strength.

User Tips

  • Regular Charging: To maximize battery life, fully charge the earphones and case regularly, even if not used frequently.
  • Secure Fit: Experiment with different ear tip sizes (if provided, or adjust placement) to find the most comfortable and secure fit for optimal sound quality and call performance.
  • Keep Clean: Regularly wipe down the earbuds to prevent earwax buildup from affecting sound output.
  • Voice Assistant: Utilize the Siri support feature for hands-free control of your device.
