Collection: Fosi Audio

Quick answer: Top Fosi Audio buys: the K5 PRO ($73.99), a gaming DAC/amp with a mic input for PC and PS5; the BT20A Pro ($92.99), a Bluetooth power amp for passive bookshelf speakers; and the Merak ($162.99), a CD player that rips discs to a USB drive and puts 210mW at 32Ω into headphones. Our 2026 CD player guide compares the Merak with SMSL and FiiO alternatives.

Fosi Audio makes small, affordable desktop gear that punches distinctly above its price — headphone amps, DAC/amp combos and compact power amps aimed at people building a desk system on a real budget. The catalogue here runs two dozen models deep, from dongle DACs to mono power and subwoofer amps.

The appeal is straightforward: enough clean power for most headphones and bookshelf speakers, useful input flexibility, and prices that leave room in the budget for the headphones themselves. A sensible first desktop upgrade if you've outgrown a dongle — our desktop DAC/amp setup guide walks through the wiring in ten minutes. Fosi is stretching, too: the I5 ($483.99) is a serious open-back planar magnetic headphone from a brand best known for electronics.
