Overview
Pocket-sized USB-C dongle DAC and headphone amplifier. Dual Cirrus Logic CS43131 chips (one per channel) drive both a 3.5 mm single-ended output (210 mW into 32 Ω) and a 4.4 mm Pentaconn balanced output (450 mW into 32 Ω) — pro-grade output power in a 25 g enclosure.
Bus-powered over USB-C; no battery, no charging, just plug into a phone or laptop. Adds a quality 3.5 mm headphone jack to any modern device — see also the USB-C → 3.5 mm adapter for a simpler passive variant.
The right portable for IEM users: drives the reference dynamic IEM, the Multi-BA IEM and the planar IEM cleanly via balanced output.
