About HiBy

Founded in 2011, HiBy Music has become one of the most prominent figures in the audio industry. They first began with an audio player app – the HiByMusic Player – which quickly became one of the most popular solutions for audiophiles using android players. So much that brands like Cayin or Hidizs even switched to HiBy for their own player – see the AP80 Pro-X for example. 


On top of that, nowadays HiBy also has a full range of players – like the R8 and RS6 – IEMs – such as the Crystal 6, WH2, and Lasya – and DAC/AMP, all embedding the brand’s own FPGA-based audio processing chips.

And today, we have the new HiBy FC4: a dual-chip portable USB-DAC, made to compete with the FiiO KA3 and iBasso’s DC06. The great contender? Time to know!

Design & Build Quality


Small and sexy, the HiBy FC4 takes a very different approach when compared to the KA3 or the DC06. When the two others favor a bulky design with visible thermal fins, the FC4 has a much sleeker approach, while retaining the all-metal body. 

Entirely made of aluminum, the HiBy FC4 looks and feels higher-end than its real price – much like the Hidizs S9 Pro – and from afar, you could easily mistake the DAC for a crypto premium USB-Key. Size-wise, the FC4 is 65.3 mm long, 22.1 mm wide, and 11.9 mm thick, and only weighs 21,7g. To those measurements, you can add the USB-C / 8-Pin cable, allowing you to connect your digital sources, like a smartphone, a computer, or a DAP. 

Thanks to that, the DAC can easily be carried in a jean pocket, a jacket, or simply stick to your phone if you’re ok with QI-wireless charging.


Build Quality

Like every product released by the brand, the HiBy FC4 is absolutely flawless in this regard. Black anodized aluminum, Bauhaus design, single-body built, and an exquisite LED light indicating the stream quality while you play your music. Add to that hardware volume buttons, and this DAC finally outmatch the NuPrime Hi-mDAC in my personal ranking.

It feels premium on and out, and for whoever wants a flawless device, with its matte-black tubular frame, but the FC4 is approximately four times cheaper, and doesn’t look four times worse…

All in all, it’s a very solid piece of work, and I can’t say bad things about the FC4 in this regard.
