The Fosi Audio ZH1 is a fully balanced desktop DAC/headphone amp built on an ESS ES9039Q2M DAC, XMOS XU316 USB and two TI TPA6120 amps, rated 2300mW x2 at 32Ω from its 4.4mm output, with web-based AI PEQ tuning. It suits PC and console gamers and headphone owners who want one hub for headphones and powered speakers.
Who the Fosi Audio ZH1 is for
Console and PC gaming: UAC 1.0 support connects it to PS5 and Nintendo Switch, and built-in Game, Movie and HiFi modes switch the sound profile.
EQ by headphone model: Fosi's Smart Acoustic Assistant builds a PEQ from a typed preference or aligns your headphone to the Harman target through a web control panel.
Headphones plus speakers: Double-tap the menu key to swap between headphone and RCA outputs, each with its own volume memory.
Hard-to-drive over-ears: The 4.4mm balanced output is rated 2300mW x2 at 32Ω, with three gain levels for 8–300Ω headphones.
Skip it if: you need Bluetooth, XLR outputs or a remote; the ZH1 has none, and its only line output is RCA.
