Fosi Audio is a dynamic Chinese Hi-Fi audio equipment manufacturer founded in January 2017 by Ryan Huang (Huang Qinglong) in Longgang District, Shenzhen, operating under parent company Shenzhen Foresight Technology Co., Ltd with fewer than 50 employees across two locations. Born from the vision of a passionate audiophile born after 1995 who started the company in a cramped 10-square-meter office with the mission to democratize high-fidelity audio by making premium sound quality accessible to ordinary people rather than just the privileged few, Fosi Audio has rapidly evolved from a DIY audio products specialist to a globally recognized HiFi powerhouse serving over 150 countries and regions across North America, Europe, and Asia. The company's name represents an acronym reflecting their core principles: Foresight (thinking further ahead), Openness (embracing users' voices), Sincerity (serving wholeheartedly), and Innovation (upholding technical excellence), with their essence being delivering authentic sound quality to users worldwide as pioneers in making HiFi accessible. Operating from their current 2,300-square-meter R&D center in Shenzhen, Fosi Audio has achieved remarkable growth with over 100 patents, strategic partnerships including supporting music education charity The Music Works, and a unique business model where 50% of products are co-developed with users through their active online community presence across YouTube, Facebook, WhatsApp, Twitter, LinkedIn, Instagram, and TikTok. Specializing in amplifiers (Bluetooth, Mono, 2-Channel, Subwoofer), Digital-to-Analog Converters (DACs), preamplifiers, headphone amplifiers, turntables, speakers, and headphones, their notable products include the V3 Mono Power Amplifier, ZA3 Balanced Dual-Mode Amplifier, ZD3 Fully Balanced Desktop DAC, BT20A Pro Bluetooth Amplifier, Luna3 Turntable, and recently launched i5 Open-Back Planar Magnetic Headphones. Known for their rapid product development cycles, commitment to in-house R&D and vertical integration, and direct sales approach through their Shopify-based website, Amazon, and AliExpress, Fosi Audio offers free lifetime technical support and 24-month manufacturer warranties while maintaining strong reputation in the Chinese DIY audio community and planning potential expansion into the pro/DJ market with a new brand. With founder Ryan Huang's personal mission to bring pure music within reach of everyone, contactable at [email protected] and +8613716612254, Fosi Audio represents a new generation of Chinese audio manufacturers combining affordability with quality, user engagement with innovation, and rapid growth with authentic audiophile passion.
