The FiiO FG3 is a wired USB gaming headset built for players who want accurate positional audio and clear team chat without paying flagship money. It is FiiO's first gaming headset, and it brings the company's hi-fi tuning experience to a closed-back, over-ear design with a detachable noise-cancelling microphone, a built-in DSP and a browser-based control panel. It is driver-free and plug-and-play: connect it by USB-C (a USB-A adapter is included) to a PC, laptop, PlayStation, Switch or smartphone and it is ready to use.
Coaxial dual-driver design
Each earcup houses a coaxial pair of dynamic drivers: a 50mm unit with a composite diaphragm for the mid and low frequencies, and a 16mm titanium-plated unit for the highs, divided by an electronic crossover at 4kHz. Because both drivers radiate from a single point, phase and directionality stay consistent, which is what gives the FG3 its precise soundstage positioning. The larger driver provides punch and clear teammate voices; the smaller one picks out fine high-frequency detail such as distant footsteps.
Built-in DSP, DAC and amplifier
A dual-core DSP handles the audio processing with low latency, the integrated DAC supports sampling rates up to 192kHz/24-bit, and a dedicated headphone amplifier delivers up to 80mW of output. A custom-tuned virtual 7.1 surround algorithm builds a 360-degree soundstage in the Cinema and Action (ACT) modes.
Detachable microphone with ENC
The detachable omnidirectional microphone uses an ENC (environmental noise cancellation) algorithm to filter out keyboard clicks and mouse taps and isolate your voice. Real-time microphone monitoring (sidetone) is processed in hardware for low latency and can be switched on and adjusted from the control panel.
FIIO Control WEB
There is no software to install. The FIIO Control web platform runs in a browser and gives access to a 10-band custom EQ and six audio presets: FPS, Action (ACT), MOBA, Rhythm (MUG), Cinema and Music. Settings are saved to the headset and retained after power loss, and firmware updates are applied through the same page. The inline control unit on the cable carries a volume slider with audio mute, an audio-mode button with a colour-coded indicator (blue for game, orange for movie, green for music) and a microphone mute button.
Comfort and portability
The ear cushions are removable and replaceable, the frame folds for packing away, and the headset weighs around 315g with the microphone fitted. The cable runs 0.7m from the headset to the inline unit over a 3.5mm TRRS connection, then approximately 1.5m to the USB-C plug.
