Why use a USB dongle?
Recover a headphone port for your modern smartphone, giving voice to the large online library of lossless music available; higher detail compared to Bluetooth audio, hearing more musical details, bringing you back closer to the original music venue in experience.
Professional audio architecture
Containing circuitry on a level with professional full-scale HiBy Digital Audio Players, which is designed solely for high-res lossless music, replaying the original music in every detail, including all its energy and presence.
Independent FPGA-based dual independent crystal oscillator reclocking
Equipped with 45.158MHz and 49.152MHz dual dedicated audio crystal oscillators for effectively lower jitter, providing the whole audio system with a high precision, low jitter clock source.
Efficient USB receiver
Driven by a highly integrated 28nm USB receiver chip of high efficiency, with the 416M dedicated audio DSP onboard to realize the best balance between high performance and long runtime, effectively lowering consumption of smartphone's battery.
My dongle is powerful than yours
340mW+340mW @32Ω is nearly unheard of for a USB dongle but here it is! Easily drive all your HiFi earphones and even some full-size headphones! High driving power is the stuff of miracles! It will let your earphones handle all music styles with more aplomb than ever, a higher sense of energy without sacrificing any fine control or detail!
High performance by the numbers
High SNR, low absolute noise level and low THD all at the forefront of products of this class, making for a faithful rendition of the great music at your fingertips on a black canvas.
MQA 16X unfolding
The HiBy FC4 includes MQA technology*, which enables you to play back MQA audio files and streams by a factor of 16x, delivering the sound of the original master recording.
ES9219's integrated DAC supports MQA full decoding of 16x unfolding.
*The smartphone must be using apps supporting bitperfect and MQA (e.g. HiByMusic, TIDAL), in order for MQA unfolding to occur with the HiBy FC4 connected via USB.
Dual ES9219 DACs
Equipped with 2 of ESS technologies’ renowned ES9219 DAC chips, set to output to each channel independently, their strong decoding power not letting go of a single musical detail.
Hi-res support
Supporting up to PCM768kHz/32bit, DSD256 (native) decoding, edging on professional HiFi in decoding specifications, this will have no problems decoding all your usual lossless streaming formats.
3.5mm SE and 4.4mm balanced brought together
Includes 3.5mm SE and 4.4mm balanced ports--balanced in position too! The attention to detail inspires confidence.
Software integration
Seamlessly integrating with HiByMusic app’s USB exclusive mode, be confident of your smartphone’s bitperfect audio output to the FC4, fully unleashing the FC4’s hardware decoding / amplification power.
