Proper ear tip selection is crucial for sound quality and comfort. Experiment with the included ear tips to find the best fit for your ears.

- Select an ear tip size that creates a good seal in your ear canal without causing discomfort.
- Push the new ear tip onto the nozzle of the earphone unit until it is firmly attached.
3.3 Wearing the In-Ear Monitors
The JH5 earphones are designed to be worn with the cable looping over your ear for a secure and comfortable fit.
- Insert the earphone unit into your ear canal.
- Guide the cable over the top and behind your ear. The cable is ergonomically designed to wrap around your ear.
- Adjust the earphone's position until it feels secure and comfortable, and you achieve a good acoustic seal.
4. Operating Instructions
4.1 Connecting to an Audio Source
The FiiO JH5 connects to audio devices via a standard 3.5mm audio jack.
- Locate the 3.5mm audio output port on your audio player, smartphone, computer, or other compatible device.
- Insert the 3.5mm plug of the JH5 cable firmly into the audio output port.
- Ensure the volume on your audio source is set to a low level before playing audio to prevent sudden loud sounds.
4.2 Using Media Controls
The JH5 cable may include an in-line remote for media control, depending on the specific cable version. Refer to your cable's specific features for detailed instructions on play/pause, track skipping, and volume adjustment.
5. Maintenance and Care
5.1 Cleaning
- Earphone Units: Gently wipe the earphone shells with a soft, dry, lint-free cloth. Avoid using harsh chemicals or abrasive materials.
- Ear Tips: Remove ear tips from the earphones. They can be washed with mild soap and water, then rinsed thoroughly and allowed to air dry completely before reattaching.
- Nozzles: Use a small, soft brush or a cotton swab to carefully remove any earwax or debris from the earphone nozzles. Ensure no moisture enters the earphone unit.
5.2 Storage
When not in use, store your JH5 In-Ear Monitors in a clean, dry place, preferably in the included carrying case, to protect them from dust, moisture, and physical damage.
5.3 Cable Care
The detachable cable is durable but should be handled with care. Avoid sharp bends, excessive pulling, or twisting, which can damage the internal wires or connectors. When disconnecting, always grasp the connector housing, not the cable itself.
6. Troubleshooting
6.1 No Sound or Intermittent Sound
- Check Connections: Ensure the 2-pin cable connectors are fully and securely inserted into the earphone units. Also, verify the 3.5mm plug is firmly connected to your audio source.
- Audio Source: Test with a different audio source to rule out issues with your device.
- Volume Level: Confirm that the volume on your audio source is turned up and not muted.
- Cable Integrity: Inspect the cable for any visible damage. If possible, test with a different compatible cable.
6.2 Poor Sound Quality (Distortion, Lack of Bass)
- Ear Tip Seal: Ensure you have a proper seal with the ear tips. A poor seal can significantly impact bass response and overall sound quality. Try different ear tip sizes or materials.
- Audio Source Quality: The sound quality is dependent on the source material and device. Try playing high-quality audio files from a reliable source.
- Cleanliness: Check if the earphone nozzles or ear tips are obstructed by earwax or debris. Clean as described in Section 5.1.
6.3 Discomfort or Poor Fit
- Ear Tip Selection: Re-evaluate your ear tip choice. A size that is too large or too small can cause discomfort or an unstable fit.
- Wearing Method: Ensure you are wearing the earphones correctly with the cable looped over your ear. Adjust the position for optimal comfort.
