Gaming has quietly become one of the most lucrative frontiers in personal audio, and at CanJam NYC 2026, Fosi Audio is stepping directly into the fight. Best known for its compact DACs, headphone amplifiers, power amplifiers, and affordable desktop gear, the company is debuting two new products aimed squarely at gamers and portable audio enthusiasts: the C3 AI Gaming Sound Card and the MD3 Magnetic DAC/Amp.
The move makes a great deal of sense. Gaming is now a multi-billion-dollar category where sound quality can make the difference between immersion and frustration, yet only a handful of established audio brands have truly taken advantage of the opportunity.
Companies like Audeze, beyerdynamic, and Sennheiser have leaned into the gaming category with some of the most respected audiophile-grade gaming headsets on the market. Meanwhile, Schiit Audio has taken a different approach, focusing on compact DAC/amp solutions such as the Schiit Gunnr and Fulla, which are designed to improve headphone audio across smartphones, tablets, PCs, and modern gaming consoles.
Fosi’s new C3 AI Gaming Sound Card feels like a logical next step for the category. By blending compact desktop audio design with gaming-focused processing and AI-assisted features, the company appears to be pushing beyond the traditional DAC/amp playbook. The big question now is whether Fosi can deliver something genuinely different from the established players—or simply prove that the next evolution of gaming audio doesn’t have to come with a high-end price tag.
The C3 AI Gaming Sound Card marks Fosi Audio’s first AI trained gaming audio processor and is designed specifically with competitive FPS (First Person Shooter) players in mind. Built on the company’s Spider S AI model, the C3 analyzes in game audio in real time to enhance critical cues such as footsteps and directional movement.
Unlike traditional EQ based “footstep boost” modes commonly found in gaming headsets, the C3 focuses on isolating movement and positional information without simply increasing overall volume or exaggerating certain frequencies. The goal is greater positional accuracy and spatial awareness while preserving the natural ambience of the game environment, rather than turning the entire soundscape into an over amplified mess.
The C3 AI Gaming Sound Card is compatible with PCs and major gaming consoles and is designed for simple plug and play operation via USB C with no drivers required. An XMOS XU316 processor works alongside a premium CS43131 DAC and a dedicated headphone amplifier to provide the computational headroom required for real time AI processing while maintaining clean, high resolution audio playback.
Hardware level 7.1 spatial audio support, AI powered microphone noise reduction, and a web based EQ control interface further expand the C3’s flexibility for both competitive and immersive gaming setups.
The C3 AI Gaming Sound Card is expected to launch soon via Kickstarter.
MD3 Magnetic DAC Amp Snaps Onto Your Smartphone
Also making its CanJam NYC 2026 debut is the MD3 Magnetic DAC/Amp from Fosi Audio. The compact DAC/amp incorporates an ESS ES9039Q2M DAC, paired with four dedicated headphone amplifier chips designed to deliver clean headroom and strong dynamic range across a wide range of headphones and in-ear monitors.
The MD3 also includes dual USB C ports that allow simultaneous playback and device charging, along with a MagSafe style magnetic back plate for secure attachment to compatible smartphones. A 1.28 inch LCD display provides direct on device control, supported by a 100 step digital volume control with memory. Internal aluminum shielding helps reduce interference, while the CNC machined aluminum chassis reinforces the unit’s durability and premium construction.
For more details on the MD3, refer to our previous article, Fosi Audio Heads to CanJam Dubai 2026 With New MD3 Magnetic and DS3 Portable DAC Headphone Amps, as well as the official MD3 product page. EIC Ian White has already previewed the MD3 and will be sharing his listening impressions from CanJam NYC 2026 this weekend, alongside Editor at-Large Chris Boylan.
“CanJam NYC allows us to connect directly with the headphone and audiophile community in one of the world’s most influential HiFi markets,” said Ryan Huang, Founder and CEO of Fosi Audio. “With C3 and MD3, we’re showing how advanced processing, balanced design, and user focused engineering can elevate both competitive gaming and portable high fidelity listening.”

The Bottom Line
With the Fosi Audio C3 AI Gaming Sound Card, Fosi Audio is stepping into the rapidly expanding gaming audio category with a product aimed squarely at competitive players who want clearer positional cues without the usual gimmicky “footstep boost” tricks. If the AI processing works as promised, the C3 could appeal to gamers looking for a more precise and natural sounding alternative to the typical headset DSP modes.
Meanwhile, the Fosi Audio MD3 Magnetic DAC Amp targets the portable hi-fi crowd, offering a magnetically attached DAC/amp designed to clean up smartphone audio without the bulk of a traditional portable stack. Between the gaming focused C3 and the smartphone friendly MD3, Fosi appears to be expanding into two fast growing segments of personal audio.
Both products will be making waves at CanJam NYC 2026, and with several other products in tow, the Fosi booth is shaping up to be a busy stop on the show floor. Check back this weekend for our full coverage and listening impressions from the event.
