Shenzhen, July 2026 – Fosi Audio is helping music lovers upgrade their audio systems this summer with its Summer Sale, running July 16 through July 26, exclusively through the Fosi Audio online store. For one week only, customers can save on a wide range of desktop DACs, amplifiers, streamers, gaming audio gear, and in-ear monitors.

Leading this year's promotion are three standout products that showcase Fosi Audio's expanding ecosystem for home, desktop, and personal listening:

Fosi Audio IM4 Single-Dynamic In-Ear Monitors – Designed for listeners who want an immersive, natural listening experience, the IM4 is Fosi Audio's first open-back in-ear monitor. Its custom 10mm beryllium-coated dynamic driver and open-back acoustic design create a spacious, speaker-like soundstage while reducing listening fatigue during extended sessions. Lightweight CNC-machined aluminum housings, a detachable cable, and premium accessories make the IM4 equally at home for critical music listening, gaming, commuting, or everyday use. Comfortable enough for all-day wear yet detailed enough to satisfy discerning audiophiles, the IM4 delivers premium performance at an accessible price.

Fosi Audio BT20A Pro Bluetooth Stereo Power Amplifier – The BT20A Pro has become one of Fosi Audio's most popular amplifiers thanks to its exceptional balance of performance, flexibility, and value. Built around the acclaimed TI TPA3255 Class-D amplifier chip, it delivers powerful, clean output while maintaining the compact footprint that has made Fosi Audio a favorite among desktop and bookshelf audio enthusiasts. Bluetooth connectivity makes wireless streaming effortless, while analog RCA inputs, bass and treble controls, a subwoofer pre-out, and swappable op-amps allow users to tailor both their setup and sound. Whether powering a first hi-fi system or upgrading an existing stereo, the BT20A Pro consistently performs well beyond its price class.

Fosi Audio S3 Streamer – The S3 is Fosi Audio's all-in-one streaming hub, combining a high-performance network streamer, balanced DAC, and preamplifier into a single elegant component. Featuring a flagship AKM DAC, balanced XLR and RCA outputs, Wi-Fi 6, Bluetooth 5.3, HDMI eARC, AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect, and Roon Ready compatibility, the S3 makes it easy to bring modern high-resolution streaming to virtually any stereo system.
