3.2 Connecting to an Audio Source
The FT7 headphones come with a 4.4mm balanced cable and adapter plugs for wider compatibility.
- For balanced outputs (e.g., high-end DACs/amplifiers), use the 4.4mm balanced connector directly.
- For standard 3.5mm or 6.35mm headphone jacks, attach the appropriate adapter plug to the 4.4mm cable connector.
- Insert the chosen connector/adapter into your audio source's headphone output.

3.3 Adjusting the Fit
- Place the headphones on your head, ensuring the earpads fully enclose your ears.
- Adjust the headband length on both sides until the headphones rest comfortably and securely without excessive pressure.
- The FT7 is an open-back design, meaning some sound will leak out and external sounds may be audible. This is normal and contributes to the wide soundstage.

4. Operating Instructions
4.1 Listening to Audio
- Ensure the headphones are properly connected to your audio source.
- Start playback on your audio source.
- Adjust the volume on your audio source to a comfortable listening level. Avoid excessively high volumes to prevent hearing damage.
4.2 Earpad Replacement
The FT7 headphones include two types of earpads, each offering a slightly different sound signature and comfort level.
- Lambskin Earpads: Provide a clear sound with a wide soundstage and highly detailed audio.
- Breathable Fabric Earpads: Offer a skin-friendly and breathable experience, enhancing the atmosphere of the music and improving vocal depth.
To replace earpads: Gently twist and pull the existing earpad off the headphone cup. Align the new earpad with the mounting ring on the headphone cup and press firmly around the edges until it is securely attached.

5. Maintenance and Care
5.1 Cleaning
- Wipe the headphone cups and headband with a soft, dry, lint-free cloth.
- For earpads, follow the specific cleaning instructions for lambskin or fabric materials. Generally, a slightly damp cloth can be used for fabric, while leather cleaners are recommended for lambskin.
- Do not use harsh chemicals, solvents, or abrasive cleaners.
5.2 Cable Care
The included cable is cryogenically treated monocrystalline copper. Handle it with care to ensure longevity.
- Avoid sharp bends or kinks in the cable.
- When disconnecting, always pull from the connector housing, not the cable itself.
- Store the cable neatly to prevent tangling.
