The FiiO Tiny B is a pocket-sized USB-C DAC and headphone amplifier that delivers an impressive dual-output configuration in one of the smallest form factors available. Unlike most USB dongles that offer a single headphone jack, the Tiny B provides both a 3.5mm single-ended output and a 4.4mm balanced output simultaneously, letting you switch between listening and calls without unplugging a thing.
Built from all-metal CNC-machined aluminium, the Tiny B Gold edition has a warm, premium finish that sets it apart from the crowd. Its compact 35 x 24 x 10.8mm body and 10g weight mean it barely registers on a keychain, yet it packs genuine hi-res credentials — PCM up to 384kHz/32-bit and DSD256 decoding via UAC 2.0 — alongside meaningful amplification: 68mW into 16Ω from the 3.5mm output and up to 45mW into 16Ω from the balanced 4.4mm port.
Connect via the FiiO Control app for precise 10-band parametric EQ, volume control with 60- or 120-step resolution, channel balance adjustment, and UAC mode switching. The onboard indicator LED confirms connection status at a glance, and in-line microphone support means the Tiny B handles calls as naturally as music. Compatible with Android, Windows, macOS, and Nintendo Switch — wherever you find a USB-C port, the Tiny B is at home.
