• Detachable 0.78 2-pin Cable: High purity monocrystalline Litz cable for improved audio transmission and reduced skin effect, leading to better bass, mids, and overall frequency coherence.
• Ergonomic Design: Designed for comfortable wear, with multiple eartip options to ensure a secure fit and optimal sound isolation.
• Stylish Celluloid Faceplates: Each unit features a unique pattern under the FiiO logo due to multiple layers of celluloid, providing a distinct aesthetic.

4. Setup

4.1 Attaching the Cable

1. Identify the left (L) and right (R) earpieces and cable connectors. The cable connectors are usually marked with 'L' and 'R'.
2. Align the 2-pin connector on the cable with the corresponding socket on the earpiece. Ensure the pins are correctly oriented.
3. Gently push the connector straight into the socket until it is firmly seated. Do not force it, as this may damage the pins.
4. Repeat for the other earpiece.

Note: The 2-pin connectors are designed for a secure fit. When detaching, pull straight out without twisting.

4.2 Selecting Eartips

Proper eartip selection is crucial for comfort, sound quality, and noise isolation. Experiment with the included eartips:

• Balanced Eartips: Provide a neutral sound signature.
• Bass Eartips: Enhance bass response.
• Foam Eartips: Offer superior noise isolation and a comfortable fit, often with a slightly warmer sound.

To change eartips, gently pull off the current tip and push the desired tip onto the nozzle until it is securely attached.

5. Operating Instructions

5.1 Wearing the Earphones

1. Identify the left and right earpieces.
2. Insert each earpiece into the corresponding ear canal. The cable is designed to loop over the top of your ear for a secure and comfortable fit.
3. Adjust the earpieces and cable until they feel comfortable and provide a good seal in your ear canal. A proper seal is essential for optimal bass response and noise isolation.

5.2 Connecting to an Audio Source

The FiiO FH1s uses a standard 3.5mm audio jack. Connect the 3.5mm plug of the earphone cable to the headphone output of your audio device (e.g., smartphone, digital audio player, laptop, tablet).

Caution: Start with a low volume level on your audio device and gradually increase it to a comfortable listening level to prevent hearing damage.

6. Maintenance

• Cleaning Earpieces: Regularly wipe the earpieces with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the drivers.
• Cleaning Eartips: Eartips can be removed and washed with mild soap and water. Ensure they are completely dry before reattaching.
• Cable Care: Avoid sharp bends or excessive pulling on the cable. Store the earphones in the provided HB1 carrying case when not in use to protect them from damage.
• Storage: Store the earphones in a cool, dry place, away from direct sunlight and extreme temperatures.
