Setup

1. Attaching the Cable

The FH5s utilizes an MMCX connector for its detachable cable. To attach the cable:

1. Identify the left (blue ring) and right (red ring) earphone units and cable connectors.
2. Align the cable connector with the earphone unit's port.
3. Push firmly until you feel a click, indicating a secure connection.

To detach the cable, use the provided MMCX assist tool. Insert the tool into the gap between the MMCX male and female seat. Press the tool vertically and use leverage to pry open the MMCX plug. Exercise caution to avoid scratching the earphone shell with the metal tool.

1. To detach a plug: Follow the arrow direction to rotate the female end until it can move back and forth. Pull the male end to detach the two ends.

3. Tuning Switches

The FH5s features three sound adjustment switches (B-M-T for Bass, Mids, Treble) on each earphone unit, allowing for 8 possible sound signatures. Use the provided tool to adjust these switches.

• B (Bass): ON for enhanced bass.
• M (Mids): ON for reduced mids.

Operating

Once the cable and desired audio plug are securely attached, and your preferred tuning switches are set, connect the FH5s to your audio source (e.g., smartphone, digital audio player, amplifier). Insert the in-ear monitors into your ears, ensuring a comfortable and secure fit. The correct ear tips are crucial for optimal sound quality and comfort. Adjust the volume on your audio source to a safe listening level before playing audio.

The semi-open design helps to quickly relieve air pressure on the ear, contributing to more comfortable and longer listening sessions.

Maintenance

Proper maintenance ensures the longevity and performance of your FH5s in-ear monitors:

• Cleaning: Use the provided cleaning brush to regularly remove earwax and debris from the ear tips and nozzle. Wipe the earphone units and cable with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
• Storage: When not in use, store the FH5s in the HB5 carrying case to protect them from dust, moisture, and physical damage.
• Cable Care: Avoid sharp bends or excessive pulling on the cable. The detachable design allows for easy replacement if the cable becomes damaged.
• Ear Tips: Periodically check ear tips for wear and tear. Replace them if they become damaged or lose their seal, as this can affect sound quality and comfort.

Troubleshooting

If you encounter issues with your FiiO FH5s, consider the following:

• No Sound or Intermittent Sound:
  • Ensure the cable is securely connected to both the earphone units and the audio source.
  • Check if the audio plug is fully inserted and locked into the cable's female end.
  • Test with a different audio source or cable to isolate the problem.
  • Verify the volume on your audio source is not muted or too low.
• Poor Sound Quality (e.g., lack of bass, distorted sound):
  • Ensure the ear tips provide a proper seal in your ear canal. Try different sizes or types of ear tips.
  • Check the tuning switch settings on both earphone units. Ensure they are set symmetrically if desired.
  • Clean the earphone nozzles and ear tips to remove any obstructions.
  • Ensure your audio source is providing sufficient power. Some high-fidelity IEMs may benefit from a dedicated amplifier.
• Uncomfortable Fit:
  • Experiment with the various ear tips provided to find the most comfortable and secure fit.
  • Adjust the cable over your ear for optimal positioning.
