FiiO JM21 vs Shanling M1 Plus: Which $200 DAP Should You Buy?

The FiiO JM21 and the Shanling M1 Plus are the two most-recommended digital audio players under $210 right now, and they take completely opposite approaches to the same job. The JM21 is essentially a thin Android 13 phone with a serious balanced output stage: streaming apps, a big 4.7-inch screen, and 700 mW of power. The M1 Plus is a palm-sized, music-only player built on Shanling's closed MTouch OS, with a physical scroll wheel and zero distractions. Both measure well past the point of audibility, so this comparison is really about how you listen — not which one "sounds better" on a spec sheet. We stock both players, so here is the honest breakdown, including the things each one gets wrong.

FiiO JM21 vs Shanling M1 Plus: Two Philosophies at $200

The JM21 ($199 for the 3GB+32GB version, roughly $210 for the newer 4GB+64GB version) bets that you stream. It runs open Android 13 on a Snapdragon 680, installs Tidal, Qobuz, Spotify, and Apple Music straight from Google Play, and applies a system-wide SRC bypass so those apps output at their native sample rate instead of being resampled by Android.

The M1 Plus ($209) bets that you own your music. There are no apps and no app store — MTouch is a Linux-based OS that boots fast, plays local files from a microSD card, and adds just enough wireless (DLNA, AirPlay receiving, two-way Bluetooth) to cover the gaps. If the idea of a music player that cannot show you a notification sounds appealing, that is the entire pitch.

Neither approach is wrong. But they are different enough that most people reading this already lean one way — the sections below should confirm or correct that lean.

Design and Handling: Scroll Wheel vs Smartphone Slab

The Shanling M1 Plus is genuinely tiny: 86 x 61 x 17 mm and 116 g, small enough for a shirt pocket or a jacket's coin pocket. The signature scroll wheel on the side handles volume and doubles as a control dial, so you can skip tracks and adjust volume without looking at the device. The trade-off is the screen: 3.2 inches at 480 x 320 is functional for browsing a library but looks dated the moment you put it next to anything modern, and cover art is visibly soft.

The FiiO JM21 goes the other way: 120.7 x 68 x 13 mm and 156 g. It is thinner than the Shanling but noticeably taller and wider — this is a small phone, not a matchbox. In exchange you get a 4.7-inch 750 x 1334 display that makes browsing a streaming catalog actually pleasant. Build quality on both is good aluminum-and-glass work; the JM21 feels sleeker, the M1 Plus feels denser.

Which is easier to live with day to day?

For gym bags, commutes, and one-handed pocket use, the M1 Plus wins on pure ergonomics. For anyone who browses playlists, reads lyrics, or manages a large streaming library, the JM21's screen is worth the extra footprint.

Under the Hood: Dual CS43198 vs ES9069Q

The JM21 uses two Cirrus Logic CS43198 DAC chips in a fully balanced architecture, feeding dual SGM8262 op-amps. FiiO's published numbers are excellent for the price: SNR of at least 130 dB and THD+N below 0.0006%. Decoding tops out at 32-bit/384 kHz PCM and native DSD256.

The M1 Plus uses a single ESS ES9069Q — a current-generation ESS chip — also paired with dual SGM8262 op-amps. Shanling quotes 122 dB SNR and 0.0007% THD+N, with decoding up to 32-bit/768 kHz PCM and DSD512. Output impedance is usefully low: 0.6 Ω single-ended and 1.2 Ω balanced, which matters for sensitive multi-driver IEMs.

Two honest notes. First, the JM21's higher SNR figure looks better on paper but both players are far beyond what anyone can hear; this should not decide your purchase. Second, the M1 Plus's DSD512/PCM768 support is equally academic — almost no real-world music exists in those formats. Call the silicon a wash and move on to the things that actually differ.

Power Output and Battery Life

The FiiO JM21 is the more powerful player: at least 245 mW per channel from the 3.5 mm output and at least 700 mW per channel from the 4.4 mm balanced output into 32 Ω. The Shanling M1 Plus delivers 195 mW single-ended and 660 mW balanced into the same load. Both drive IEMs and most dynamic-driver headphones with ease; neither is a planar-magnetic powerhouse, and the JM21's edge is real but modest.

Battery is more nuanced. The original JM21 (3GB+32GB) carries a 2400 mAh cell rated at 12.5 hours single-ended and 9.5 hours balanced. The updated 4GB+64GB version bumps that to 3100 mAh — 16 hours single-ended, 12.5 hours balanced. The M1 Plus has a 2100 mAh battery rated up to 12.5 hours, and because MTouch is far lighter than Android, real-world drain while idle is lower. Android players lose charge in your pocket doing background Android things; the Shanling mostly doesn't.

If battery is your top priority, buy the 64GB JM21 specifically — the 32GB version's 9.5-hour balanced figure is the weakest number on this page.

Software: Android 13 Streaming vs MTouch Simplicity

This is the real dividing line. The JM21 runs open Android 13 with full Google Play access. Tidal, Qobuz, Spotify, Amazon Music, YouTube Music, Apple Music, Plex, Roon ARC — if it is in the Play Store, it runs, and offline downloads work exactly as they do on a phone. FiiO also includes a Pure Music mode that boots straight into the FiiO Music app when you want fewer distractions. The Snapdragon 680 is not fast by 2026 smartphone standards — app installs and heavy library scrolls show occasional hesitation — but it is comfortably the smoothest Android experience at this price.

The M1 Plus cannot install any third-party apps, full stop. What MTouch offers instead: a responsive, single-purpose interface; DLNA streaming from a NAS; AirPlay receiving from an iPhone; OTA updates over 2.4/5 GHz Wi-Fi; and two-way Bluetooth 5.2 with LDAC and aptX HD, so it works as both a transmitter and a high-quality receiver for your phone. It also has a party trick the FiiO lacks: a coaxial S/PDIF output through the 3.5 mm jack, letting it feed a desktop DAC as a digital transport.

One more storage caveat: the M1 Plus has no internal storage at all. Budget for a microSD card (both players accept up to 2 TB) or it plays nothing out of the box.

How They Sound

With identical op-amps and vanishingly low distortion on both, the audible differences are small — smaller than a pad swap or an ear-tip change. That said, the house tendencies hold: the M1 Plus leans near-neutral with a touch of mid-bass warmth and clean, extended treble, typical of well-implemented ESS designs. The JM21 sits slightly warm-of-neutral and relaxed, in classic Cirrus Logic fashion, which makes it forgiving with brighter IEMs. If you are choosing purely on sound, pick based on your headphones' tonal balance rather than the players themselves — your transducer contributes ten times more to the result than either DAC.

FAQ

Which has better battery life?

The 64GB FiiO JM21, clearly: 16 hours single-ended and 12.5 hours balanced from its 3100 mAh cell. The M1 Plus manages up to 12.5 hours single-ended, and the original 32GB JM21 trails on balanced at 9.5 hours. The Shanling claws back ground in standby — its lightweight OS barely sips power when paused, while Android drains steadily in the background.

Can the FiiO JM21 run streaming apps?

Yes — this is its defining feature. Open Android 13 with Google Play means Tidal, Qobuz, Spotify, Apple Music, and Amazon Music all install natively, with offline downloads to internal storage or microSD. FiiO's system-wide SRC bypass keeps those apps bit-perfect. The Shanling M1 Plus cannot install any streaming app; its wireless options are limited to DLNA, AirPlay, and Bluetooth from a phone.

Which is better for IEMs vs full-size headphones?

For sensitive IEMs, the M1 Plus is arguably the safer pick thanks to its published 0.6 Ω single-ended output impedance and lower gain floor — hiss-prone multi-driver sets stay quiet. For higher-impedance or less efficient full-size headphones, the JM21's ≥700 mW balanced output gives it more headroom. Realistically, both drive 95% of IEMs and portable headphones well; neither should be bought to drive demanding planars.

Can both work as USB DACs?

Yes. Plug either into a laptop over USB-C and it becomes an external DAC/amp — the M1 Plus accepts up to 768 kHz/DSD512, the JM21 up to 384 kHz/DSD256. The Shanling additionally works as a pure digital transport via its coaxial output.

Verdict: Which One Should You Buy?

Buy the FiiO JM21 if:

• You stream from Tidal, Qobuz, Spotify, or Apple Music — nothing else at this price does it properly
• You want the bigger, sharper screen and don't mind a phone-sized device
• You need maximum power for harder-to-drive headphones (get the 64GB version for the better battery)

Buy the Shanling M1 Plus if:

• Your library lives on a microSD card and you want a distraction-free, pocket-friendly player
• You value physical controls — the scroll wheel is the best eyes-free interface under $300
• You'll use the extras: coax S/PDIF transport duty, AirPlay/DLNA, or two-way Bluetooth 5.2

If we had to pick one for most American buyers in 2026, it's the JM21 — streaming access simply matters to more people than a scroll wheel does. But the M1 Plus is the better second device for anyone who already carries a phone and wants their music somewhere quieter.
