FiiO is a Chinese portable-audio company founded in 2007 in Guangzhou that began with pocket headphone amplifiers and now makes DACs, digital audio players, in-ear monitors, and headphones.

A palm-sized, USB-powered DAC/amp that reviewers found clean and quiet — and that owners split on for power and staying power.

A sixty-dollar Bluetooth DAC with a battery you can swap — and a battery everyone has an opinion about.

The dongle that behaves like a desktop amp — including the heat, the appetite for power, and a menu with more ambition than its software.

Desktop-class numbers in an 8.5-gram dongle for $33 — and a long argument about heat, the cable, and how long it lasts.

The budget closed-back everyone recommends — and a louder chorus than you'd think that sends it back.

One retro box for the whole desk — the arguments are whether the AKM inside it has a sound, and whether the firmware has finished growing up.

A $160 planar three rigs call near-neutral — and that listeners hear as bassy, V-shaped, or bright.

The most capable Bluetooth DAC/amp under $200 by almost every account — and the one whose software, radio and battery every account then argues about.

Four benches agree on the graph. Almost nobody agrees on what it sounds like.

A 21-gram cassette deck that out-measured every dongle on the bench — then needed a firmware update to close the argument about it.

A 2.7 kg box of connectors and clean power — where reviewers argue is whether the AKM chip inside it has a sound at all.

A 60 mm open-back with bass no HD 600 can match — and a top end that two measurement rigs describe as opposite things.
