Unboxing

Sound
The first thing that struck me about the HiBy FC5’s overall sonic performance was the amount of detail produced. With an overall neutral sound.
The HiBy FC5 also has a smooth character that some might mistake for warmth. One of the most impressive aspects of the HiBy FC5 is its ability to maintain excellent timbre, not too warm, not too clinical, and excellent tonality for this kind of a dongle DAC.
Lows
The bass response on the HiBy FC5 is punchy and deep, with good extension into the sub-bass regions without overpowering the other frequencies. It retains control even in bass-heavy tracks, with no signs of muddiness. The slightly warm tuning gives the low-end a bit of extra body.
What I particularly enjoyed was that even in bass-heavy tracks, the instruments remained clean and well-separated, providing a solid foundation without interfering with vocal clarity or instrumental detail.
Mids
Mids are where the HiBy FC5 impresses even more, with a natural, fluid timbre that accurately reflects the nuances in vocals and instruments. Both male and female vocals have a realistic rendering, sitting comfortably in the mix without being pushed too far forward or recessed.
Instruments like guitars, pianos, and strings are rendered with a rich timbre. Instruments have a realistic body, which is another highlight of the FC5, IMO. There’s a sense of realism, and the slight warmth that the FC5 possesses does not make it sacrifice detail, making the HiBy FC5 an especially versatile device for any genre.
Highs
The treble on the HiBy FC5 is smooth and extended, providing plenty of detail without ever crossing into harshness or sibilance. It offers just the right amount of sparkle to add air and clarity to the mix while remaining easy on the ears during longer listening sessions.

The upper mid/lower treble sounds extended and clean, yet never sharp. Cymbals, hi-hats, and other lower treble-dependent instruments are rendered with a crisp but controlled edge, ensuring they never dominate the sound signature or introduce shoutiness.
Even with brighter recordings, the HiBy FC5 manages to keep everything balanced, providing a pleasant top-end that goes excellently with the rest of the frequency range.
Technicalities
The HiBy FC5 excels in technical performance, offering a fairly wide and enveloping soundstage for a dongle in this price range. The soundstage is expansive enough to give a sense of great space and separation, creating an accurate holographic stage image.
The instrument separation is especially excellent for the price. The HiBy FC5 allows each instrument to breathe, avoiding congestion even during complex passages.

Sum-Up
I lost count on dual CS43198-based dongle DACs. The HiBy FC5 2025 stands out with its big 1.1″ color OLED screen. Also, the design catches you from the first moment.
The overall sound presentation is fairly detailed, focusing on naturality across the frequency spectrum. From clean, crisp high-resolution audio signal processing to powerful output, the FC5 2025 does its all.
If you are in the market for your first dongle DAC to buy, you can put the HiBy FC5 2025 on top of your list.
