The Hiby FC4 is a compact and lightweight dongle DAC/amplifier designed for audio enthusiasts who seek enhanced sound quality on the go. Featuring dual ES9218PC DAC chips, this unit delivers a warm, neutral, and full-bodied sound, making it suitable for various audio genres and equipment. It has a sturdy aluminum construction with a sleek matte finish, blending durability and aesthetics. The FC4 includes independent volume control buttons, allowing users to adjust the volume separately from the source device, offering greater flexibility in audio management. With an output power of 110mW (single-ended) and 340mW (balanced) at 32 ohms, it can drive a wide range of IEMs and headphones effectively. The capability to maintain the last volume setting between uses adds to its user-friendly design. Despite its modest size, the FC4 manages to pack significant power, with a battery drain test revealing low consumption rates while driving demanding headphones. Its performance is complemented by support for high-resolution formats, including PCM up to 32-bit/768kHz and DSD256. The device is equipped with both 3.5mm and 4.4mm outputs, catering to different user preferences for connectivity. Although it lacks advanced EQ or filter options without the Hiby Music app, it excels in delivering a satisfying audio experience, especially for those who prioritize a full and organic sound. At a retail price of $79, it is positioned as a value choice for portable audio solutions.
