The FiiO JM21 is a slim 156g Android 13 music player with dual CS43198 DACs and 700mW per channel into 32Ω from its 4.4mm balanced jack. It's aimed at listeners who want streaming apps on a dedicated player instead of their phone, and it also works as a USB DAC at a desk.

Who the FiiO JM21 is for

  • Streaming subscribers: Android 13 installs Tidal, Qobuz, Spotify or Apple Music from Google Play and streams them over 2.4/5GHz Wi-Fi.
  • Balanced IEM and headphone owners: The 4.4mm output is rated at 700mW per channel into 32Ω, nearly three times the 245mW from the 3.5mm jack, so a balanced cable unlocks the extra power.
  • One device for commute and desk: Plugged into a computer over USB-C, it works as a USB DAC up to 384kHz/32-bit and native DSD256.
  • Local-file collectors: About 52GB of the 64GB is free for music, and FiiO quotes microSD support for cards up to 2TB.
  • Saving your phone battery: Playback moves off the phone; FiiO rates the 4GB+64GB JM21 at up to 16 hours from the 3.5mm output and 12.5 hours balanced.
  • Skip it if: you need to drive power-hungry planar-magnetic headphones; its output suits IEMs and most portable dynamic headphones rather than demanding planars.

FAQ

Can I run Tidal, Qobuz, or Apple Music on it?

Yes. The JM21 runs Android 13 with full Google Play access, so Tidal, Qobuz, and Apple Music install and run natively over Wi-Fi — no locked-down skin or workarounds.

JM21 or the Shanling M1 Plus at a similar price?

Pick the JM21 if you want streaming apps installed directly — its open Android 13 is the key difference. The Shanling M1 Plus is smaller and simpler but runs MTouch OS without native app installs. Both offer strong 4.4mm balanced output, and both can double as a USB DAC for your desk.

Is 64GB storage enough?

The current 4+64GB build fixes the original model's tight storage, the main earlier complaint; FiiO lists about 52GB of it as usable. For streaming-focused use it is plenty, and heavy local-file collectors can add a microSD card (FiiO quotes support for cards up to 2TB). Backed by a 1-year TonePier warranty, 45-day returns, and free shipping on genuine brand-new stock.

FiiO JM21 vs similar options

  • vs Shanling M1 Plus: Runs Shanling's music-only MTouch OS with no app installs, in a smaller 116 g body rated 660mW balanced at 32Ω; pick the JM21 for Google Play streaming apps and a 4.7-inch screen.
