Setup and Connection

1. Choose Earpads: Select either the Protein leather earpads for a clear sound or the Suede earpads for a more balanced and atmospheric sound. The Suede earpads are pre-installed. To change, gently pull off the current earpads and align the new ones with the headphone cups, pressing firmly around the edges until they click into place.
2. Attach Cable: Connect the dual 3.5mm plugs of the high-purity monocrystalline copper cable to the corresponding jacks on the bottom of each headphone cup. Ensure a secure connection.
3. Select Audio Plug: The 4.4mm balanced plug is pre-installed on the cable. If your audio source requires a different connection, swap the plug:
   • To remove, twist and pull the current plug from the cable.
   • To attach, align the desired plug (3.5mm, 6.35mm adapter, or XLR-4 adapter) and push it firmly into the cable connector until it locks.

4. Connect to Audio Source: Plug the selected audio connector into your compatible device (e.g., headphone amplifier, DAC, digital audio player, computer). The FT5 headphones are designed to be easily driven but benefit from a dedicated amplifier for optimal performance.

Operating Instructions

The FiiO FT5 headphones are designed for high-fidelity audio reproduction. Follow these guidelines for optimal listening:

• Volume Control: Adjust the volume using your audio source device. The FT5 headphones do not have integrated volume controls on the earcups.
• Comfort and Fit: Adjust the headband to ensure a comfortable and secure fit. The open-back design allows for natural sound and reduces pressure on the ears during long listening sessions.
• Listening Environment: As open-back headphones, the FT5 allows sound to escape and ambient noise to enter. For the best listening experience, use them in a quiet environment.
• Burn-in Period: Like many high-fidelity audio products, the FT5 may benefit from a "burn-in" period of several hours of use to allow the drivers to settle and achieve their optimal sound characteristics.

Maintenance and Care

Proper care will extend the lifespan and maintain the performance of your FiiO FT5 headphones:

• Cleaning: Use a soft, dry cloth to wipe the headphone surfaces. Do not use liquid cleaners or solvents. For earpads, refer to specific cleaning instructions for protein leather or suede.
• Storage: When not in use, store the headphones in the provided luxurious leather storage case or velvet bag to protect them from dust and physical damage.
• Cable Care: Avoid sharp bends or excessive pulling on the cable. Disconnect the cable by gripping the plug, not the cable itself.
• Environmental Conditions: Do not expose the headphones to extreme temperatures, high humidity, or direct sunlight. They are not water-resistant.
• Earpad Replacement: Earpads are consumable items and may need replacement over time due to wear. Replacement earpads can be purchased from authorized FiiO retailers.
