HiBy FC3 USB DAC Headphone Amp with OLED Display

The HiBy FC3 is a compact USB DAC and headphone amp with an OLED display that delivers full-format Hi-Res playback, MQA unfolding, and up to 112mW per channel to drive demanding headphones.

Small enough to carry on-the-go yet built around the ES9281AC Pro decoder, the FC3 turns phones and computers into high-quality audio sources. It supports PCM up to 32bit/384kHz, DSD128 over DoP, and MQA decoding for a closer-to-studio listening experience. The integrated headphone amplifier and clear OLED make it practical for desktop and mobile use without any charging — just plug in and play.

How does the FC3 improve everyday listening from phones and laptops?

The FC3 replaces a device’s built-in DAC with a higher-performance converter and dedicated amp, reducing noise and improving clarity, detail, and dynamics. Its OLED display gives immediate feedback on format and level, helping you confirm sample rates and MQA status at a glance.

• ES9281AC Pro chipset for full-format decoding
• Displays sample rate, volume, and input format on OLED
• Plug-and-play on Mac and Windows 10; simple adapter setups for mobile

Can the FC3 handle high-resolution and MQA files?

Yes — the FC3 supports PCM up to 32bit/384kHz and DSD128 DoP, enabling native playback of most Hi-Res formats. It also performs MQA unfolding so you can access studio-intended detail when using MQA-enabled players such as HiBy Music or TIDAL.

• PCM: up to 32bit/384kHz
• DSD: DSD128 via DoP
• MQA: full unfolding with compatible software for enhanced detail

Will it power my headphones and how loud will it get?

The FC3 provides 112mW per channel into 32Ω, which is ample for most portable and many desktop headphones, offering improved dynamics and headroom over typical phone outputs. It can drive efficient to moderately demanding models comfortably; very high-impedance or low-sensitivity flagship cans may need a dedicated amp for full scale.

• 112mW+112mW output at 32Ω for stronger drive
• Low-noise headphone amp stage for cleaner dynamics
• Works with a wide range of headphones from IEMs to medium-power over-ears

How easy is the FC3 to use across devices and apps?

The FC3 is designed for minimal setup: plug it into a Mac or Windows 10 computer for immediate use as a sound card, and connect to iPhone or Android devices using the appropriate adapter. For MQA unfolding and advanced features, use compatible players such as HiBy Music or TIDAL on your smartphone.

• Plug & play on macOS and Windows 10 — no charging required
• Works with iPhone and Android with the correct OTG/Lightning adapter
• MQA features available with supported players (HiBy Music, TIDAL)

Who is this for? The HiBy FC3 suits listeners who want a portable, higher-fidelity audio path from their phone or computer without carrying a full-sized desktop DAC/amp. It’s ideal for commuters, audiophiles who travel, and anyone wanting clearer detail, better dynamics, and transparent MQA support from streaming and local Hi-Res files. If you need maximum power for very inefficient, high-impedance flagship headphones, consider pairing the FC3 with a more powerful standalone amp; for most users and headphones, the FC3 offers a substantial upgrade over native device audio.
