Fosi Audio made a high-profile appearance at AXPONA 2025 in Chicago from April 11 to 13, where we revealed our upgraded brand strategy and a range of next-generation HiFi products under the theme “Building an Inclusive HiFi Ecosystem for Audiophiles Worldwide.” This event marks the official debut of our all-new HiFi audio ecosystem, featuring multiple upcoming releases including the highly anticipated SP601 passive bookshelf speakers and i5 planar magnetic headphones.
Brand Revamp: Making HiFi Accessible Through Innovation
At AXPONA 2025, we introduced our new brand vision — “A New Audio Tech Brand Bringing HiFi Joy to Audiophiles Worldwide” — while reaffirming our mission of “Redefining HiFi with Unmatched Value.” Focused on user-centric innovation, we are dedicated to lowering the barrier to high-fidelity audio and making superior sound accessible to more people.
Our core philosophy is reflected in our name — FOSI, which stands for four key values:
Foresight – Visionary thinking and proactive solutions for the future
Openness – Co-creating with audiophiles by listening to users
Sincerity – Putting users first with a commitment to quality
Innovation – Breaking technological boundaries to exceed expectations
We also introduced our new slogan: “HEAR THE UNHEARD.” This bold statement embodies our relentless pursuit of audio performance and fidelity, while emphasizing our belief that user needs drive innovation.
A Complete HiFi Chain: Showcasing the Future of Home Audio
We understand that today’s audio enthusiasts seek more than just individual products — they want fully integrated, high-quality HiFi solutions. That’s why, at AXPONA, we showcased a full-system lineup, including upcoming source devices like the Luna 3 turntable and Merak CD player, the ZP3 preamp, E30 cinema-grade DAC amplifier, passive speakers, subwoofers, and over-ear headphones. This all-in-one HiFi ecosystem delivers a seamless audio experience from source to sound output. Visitors were impressed by the products’ premium design, intuitive usability, and stunning sonic performance — echoing the sentiment that “the future of HiFi has arrived.”
Flagship Product Highlights: SP601 & i5 Planar Headphones
SP601 Passive Bookshelf Speakers
Equipped with a 6.5-inch paper-aluminum composite woofer, a 1.5-inch silk dome tweeter, and a rear-firing bass reflex port, the SP601 delivers warm and natural highs, clean mids, and tight, punchy lows. Its lightweight diaphragm ensures rapid transient response and expansive soundstage, making it an ideal choice for both music listening and home theater setups.
Featuring a 97mm ultra-thin nano diaphragm driver, the i5 adopts industry-first sputtering technology and an acoustically optimized damping back cavity design. These innovations reduce resonance and enhance transients, resulting in a clear and natural sound signature. The headphone also features breathable ear cushions, a memory metal headband, and seamless silicone adjustment for long-term comfort — ideal for both casual listening and professional monitoring.
The i5 will officially launch on Kickstarter on April 20, with the prelaunch page now available for early preview: Kickstarter Preview.
