FiiO Retro Nano Bluetooth DAC and Headphone Amplifier
Overview
The FiiO Retro Nano is a pocket-sized Bluetooth DAC and headphone amplifier styled after a vintage tape recorder, from FiiO's SnowSky sub-brand. Plug in your wired headphones or IEMs, pair it with your phone and it handles the conversion and amplification, with a small colour screen showing a retro-themed interface. It's for listeners who want better sound from wired headphones on the go, in a design that's more fun than the usual black dongle.
Two Cirrus Logic CS43131 DAC chips feed both the 3.5mm single-ended and 4.4mm balanced outputs, and the amplifier stage has its own power supply, reaching up to 220mW per channel into 32 ohms from the balanced jack. A Qualcomm QCC5125 handles Bluetooth 5.1 with LDAC, aptX Adaptive, aptX HD and aptX Low Latency, and both wireless and wired playback reach 96kHz.
The 450mAh 3.7V battery is removable, so a second charged battery can be swapped in, and the Retro Nano also runs straight from USB power with no battery fitted, which suits car use or a connection to powered speakers. A double press of the multi-function button switches between Bluetooth, PC and PHONE modes. It has eight sound presets, including retro-voiced ones, plus custom EQ in the FiiO Control app.
Simcoe Audio Video Insight
Battery life is about 7.5 hours over Bluetooth and about 9 hours as a wired USB DAC in PHONE mode, and it charges in two hours or less from a standard 5V/2A charger, since it doesn't support fast charging. Only one battery is included, so if you want to swap mid-day, plan on picking up a compatible 3.7V 10440 cell; standard AAA batteries won't work. The 3.5mm jack supports CTIA in-line remote and mic controls, and the built-in mic handles calls over Bluetooth. Keep in mind it's a receiver only: it can't send audio to wireless headphones.

Buyer's Guide
Who It's For
- The Style-Minded Listener: Wants a Bluetooth DAC/amp that stands out.
- The Wired IEM User: Wants LDAC wireless or a USB DAC for a phone.
- The Car and Speaker Listener: Wants to run from USB power without a battery.
How It Compares
Within FiiO's range of Bluetooth DAC/amps, the Retro Nano is the one built around a vintage tape-recorder body, a colour screen with a retro interface and a removable battery that can be left out entirely when running from USB power, while still offering dual CS43131 DACs, a 4.4mm balanced output and LDAC.
