The FiiO M21 has arrived at CEN — a compact hi-res digital audio player that brings FiiO's flagship engineering down to £329, for listeners who want their music off the phone and onto dedicated hardware.
Why a dedicated player in 2026?
Phones are compromise machines: shared batteries, noisy internals and audio circuits chosen by accountants. A DAP exists for one job. The M21 pairs proper conversion and amplification with a pocketable body — FiiO's "entry-level with flagship lineage" positioning is fair, because the architecture is inherited from far pricier players.
Living with it
Local hi-res files, streaming over WiFi and Bluetooth for the car or wireless headphones — it covers the modern listening map, with a compact screen that keeps it genuinely pocketable rather than a second phone. Wired output is where it earns its keep: this is the difference your good IEMs have been waiting to demonstrate.
Our take
At £329 the M21 is the sensible entry into serious portable audio — enough performance to be a destination, cheap enough to be a first step. It sits neatly between the iFi Go Link 2 Max dongle and the desktop FiiO K15 in our range; ask us which rung of the ladder fits how you listen.
Frequently asked questions
Does the M21 replace my phone for streaming?
It runs streaming apps itself over WiFi, so yes — with dedicated audio hardware doing the playback instead of a phone chipset.
Do I need special headphones?
No, but the M21 has the clean output to reveal what good wired headphones and IEMs can do — it scales with whatever you plug in.
DAP or dongle DAC?
A dongle like the iFi Go Link 2 Max upgrades the phone you already carry; a DAP is a dedicated music device with its own storage, screen and battery. The M21 is the step up when music deserves its own hardware.
