Cyborg dongle

Extending the new generation of cyborg-inspired HiBy designs, the dongle chassis is an innovative blend of aluminium alloy and translucent polycarbonate, exuding personality.

Weighing only 21 grams, the featherlight compact device can be taken everywhere with you and connected to your smartphone, etc., without fuss.

Compared with HiBy FC5 with display, the new FC4 uses the same DAC but has a lower power amplifier with a lower noise floor, making it more suitable for IEMs.

Equipped with not one but two high-performance Cirrus Logic flagship MasterHiFi CS43131 DACs with built-in hi-res headphone amplification.

Blending advanced audio technology with low power consumption design, it delivers a pure, detailed high-fidelity listening experience even with power-hungry headphones, without excessive battery drain on your smartphone.
