Hey, what’s cracking everyone—this video is all about the Fosi Audio DS3, a tiny $100 portable dongle DAC/amp that’s clearly aimed at gamers. It’s rocking an ESS Sabre DAC plus an XMOS processor (first time for them here), and the big headline features are the built-in 7.1 virtual surround and a hardware FPS mode. I go over the build (CNC aluminum, tactile buttons, transparent glass back), the I/O (USB-C in, 3.5 and 4.4 out), and the basic usability stuff like LED colors, gain behavior, volume memory, and the seven digital filters you can cycle through in UAC 2.0 mode. For sound, I found it mostly neutral with a touch of treble “hotness” depending on the headphone/IEM, and a slightly wider stage—nice for gaming. Power tops out at 220mW balanced, which isn’t crazy, but it handled a lot: even my HD600 needed high gain and more volume, and sensitive IEMs like the FlipEars Arion didn’t give me noise floor issues. Gaming is where it gets spicy: 7.1 made Battlefield and RPGs feel more immersive, and the FPS mode is honestly one of the best implementations I’ve heard because it boosts the right details without making everything else sound flat. My biggest knocks are the clunky UAC switching, the flashing high-gain light, no easy mobile EQ access, and the lack of CTIA mic passthrough on 3.5—kinda gamebreaking if you want one-device audio + comms.
