Know before you buy
By using six drivers across a three-way crossover, the FA7s assigns specific frequency ranges to dedicated drivers. This minimizes interference between the bass, mids, and highs, resulting in a cleaner, more detailed, and balanced sound profile.
Yes, the FA7s uses a standard MMCX connector, allowing you to easily detach and replace the cable if needed. The included high-purity silver-plated monocrystalline copper cable is designed for optimal signal transmission, but the universal connection gives you the flexibility to use aftermarket cables.
With an impedance of 18Ω and a sensitivity of 111dB, the FA7s is relatively easy to drive. While they will work well with most smartphones and laptops, using a dedicated DAC or amplifier can help you extract the full potential and clarity of the Hi-Res audio performance.
The twist-lock system allows you to quickly switch between 2.5mm, 3.5mm, and 4.4mm plugs without needing to replace the entire cable. This makes the FA7s highly versatile if you frequently switch between different audio sources or balanced and unbalanced outputs.
The 316L stainless steel provides a premium, durable feel and a sleek finish. While it is slightly heavier than plastic alternatives at 8.4g per earbud, the ergonomic shape and angled MMCX connectors are designed to sit securely and comfortably in the ear for extended listening sessions.
Hi-Res Audio certification confirms that the FA7s is capable of reproducing a wider frequency range—specifically up to 40kHz—than standard headphones. This ensures that you can hear more detail and nuance in high-resolution audio files, providing a more natural and accurate sound reproduction.
