Setup and Connection
Connecting the Cable to the Earphones
- Identify the left (L) and right (R) earpieces and the corresponding connectors on the cable. The connectors are typically color-coded (e.g., blue for left, red for right) or marked with 'L' and 'R'.
- Align the 0.78mm 2-pin connector with the port on the earpiece.
- Gently push the connector straight into the earpiece port until it is securely seated. Do not force the connection.
- Repeat for the other earpiece.

Operation
Wearing the Earphones
- Select the appropriate size and type of ear tips for a comfortable and secure fit. A good seal is crucial for optimal sound quality, especially bass response.
- Insert the earpieces into your ears, ensuring the cable loops over your ear for stability. The ergonomic design is intended for a secure fit.
Audio Playback and Control
Once connected to your audio device, you can control media playback (e.g., play, pause, skip tracks) and volume directly from your device. The JH3 earphones themselves do not feature integrated media controls on the cable.
Maintenance
Cleaning
- Regularly clean the ear tips with a soft, dry cloth to remove earwax and debris. For silicone tips, they can be gently washed with mild soap and water, then thoroughly dried before reattaching.
- Wipe the earpieces and cable with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials.
Storage
When not in use, store the earphones in the provided carrying case to protect them from dust, moisture, and physical damage. Avoid extreme temperatures.
Troubleshooting
No Sound or Intermittent Audio
- Check Connections: Ensure the 0.78mm 2-pin connectors are firmly attached to the earpieces and the 3.5mm jack is fully inserted into the audio source.
- Volume Level: Verify that the volume on your audio device is not muted or set too low.
- Test with Another Device/Cable: Try connecting the earphones to a different audio device or using a different compatible cable to determine if the issue lies with the earphones, cable, or source device.
Poor Sound Quality (e.g., weak bass, muffled sound)
- Ear Tip Seal: Ensure the ear tips create a proper seal in your ear canal. Experiment with different sizes and types of ear tips to find the best fit.
- Clean Ear Tips/Nozzles: Accumulated earwax or debris can obstruct sound. Clean the ear tips and check the earphone nozzles for blockages.
- Audio Source Quality: Ensure the audio source file or streaming quality is high resolution.
