■Large-diameter 14.2mm hybrid driver delivers depth and brilliance
- Thorough pursuit of sound quality for intra-concha earphones has led to the development of a large-diameter 14.2mm dynamic driver. The hybrid diaphragm features a PU (polyurethane) diaphragm with a beryllium coating on the dome. The highly rigid and lightweight beryllium reduces unnecessary resonance, delivering lustrous mid- and high-range sounds, while the large-diameter PU diaphragm delivers dynamic and natural low-range sounds.

■Newly designed housing and acoustic tube enhance deep bass
- The newly designed drum-shaped earphone housing, inspired by the drum instrument, effectively enhances the resonance and texture of low frequencies. Furthermore, the ""acoustic tube structure"" maximizes the space inside the housing, lowering the resonance point and achieving a low frequency of 90Hz and an effective frequency range of up to 42.5Hz when worn with standard open-type earphones. Experience deep, sharp bass sounds that were previously difficult to achieve with intra-concha earphones.

■ Dramatically Lightweight and Detachable Cable for Comfort and Convenience
- By using an aluminum alloy housing, the headphones are approximately 52% lighter than the base model FF3. Weighing just 3.9g per earphone, they reduce fatigue even during extended listening sessions. The unique 0.78mm 2-pin detachable cable allows for easy replacement and re-cabling.

■ High-Quality Cable and Interchangeable Plugs for Optimized Sound Quality
- A high-quality cable with a total of 152 high-purity silver-plated single-crystal copper wires is included as standard. Tuned to improve high-frequency resolution while reducing unwanted friction noise, the included 3.5mm/4.4mm interchangeable earphone plugs allow you to easily and reliably switch between single-ended and balanced drive modes to suit your device and application.

■ Customized Sound Quality and a Wide Range of Accessories
- Two types of sponge covers are included, allowing you to choose between bass-emphasis and clarity, allowing you to tailor the sound quality to your preferences. It also comes with a silicone ring cover and wing hook to help prevent it from falling off and improve the fit.
