Dual CS43198 DACs
700mW balanced output
Snapdragon 680
Android 13
156g lightweight
32GB + 2TB microSD
I started my testing with the JM21 because it represents the most accessible entry point into serious portable audio. At $179, I expected compromises. What I found instead was a device that punches well above its weight class.
The dual CS43198 DACs are the same chips found in players costing three times as much. Paired with SGM8262 operational amplifiers, the JM21 outputs 700mW per channel in balanced mode. That is enough power to drive most portable headphones and many full-size models to satisfying volume levels.
The Android 13 experience is surprisingly smooth thanks to the Snapdragon 680 processor. I installed Tidal, Spotify, and FiiO’s own music app without issues. The unlocked bootloader is a nice touch for the tinkerers who want to customize their experience beyond stock.
Sonic character leans slightly warm and musical. Detail retrieval is excellent for the price, though the soundstage is more intimate than expansive. I found the JM21 particularly well-suited for IEMs and efficient dynamic driver headphones.
Battery life is the main compromise. FiiO claims 12.5 hours, but in my testing with mixed usage including some streaming over WiFi, I got closer to 9-10 hours. The buttons are also placed where they can press accidentally in a pocket, though the included silicone case helps.
For anyone curious about dedicated DAPs but hesitant to spend big money, the JM21 removes that barrier. It delivers genuine hi-res audio performance in a package that fits anywhere.
Best Pairings for the JM21
The JM21 excels with efficient IEMs and portable headphones. I tested it with the Moondrop Aria and Sennheiser HD 400S with excellent results. The 700mW output has enough headroom for most sub-100 ohm loads.
For home listening, the single-ended output works well with powered speakers or as a source to an external amplifier. The USB DAC mode lets it function as a desktop audio interface when connected to a computer.
Who Should Skip the JM21
Users with demanding planar magnetic headphones like the HiFiMan Ananda or Audeze LCD series will want more power. The 700mW output, while impressive for the size, falls short of what those headphones need to truly sing.
Anyone needing all-day battery life without charging should look at the M21 or higher models. The JM21 requires nightly charging with heavy use.
2. FiiO M21 – The Sweet Spot for Most Listeners
- Quad DAC Matrix design
- Desktop Mode with battery bypass
- Warm musical sound signature
- Modern Android 13
- Excellent PEQ with Stereo Expand
- SPDIF output for digital systems
- Some units have faint crackling
- Display issues on some units
- Storage needs microSD expansion
- Not the flagship DAC chips
Quad CS43198 DACs
950mW Desktop Mode
Snapdragon 680
Android 13
SPDIF output
193g
The M21 sits at what I consider the perfect intersection of price, performance, and features. At $369, it doubles the DAC count to four CS43198 chips in a matrix configuration and adds the Desktop Mode feature that transforms how you can use this player.
Desktop Mode is the standout feature here. When connected to power, the M21 can bypass its internal battery and run entirely off AC. This extends the battery’s lifespan significantly for home use and allows the amplifier to reach its full 950mW output potential without power management constraints.
I spent two weeks using the M21 as my primary desktop source, connected to a Schiit Magni amplifier and Sennheiser HD 650 headphones. The sound quality rivals dedicated desktop DACs I have used costing $500 or more. The warm, full-bodied presentation makes long listening sessions engaging without fatigue.
The 31-band parametric EQ is powerful. The Stereo Expand feature adds width to narrow recordings without the phase issues common with simple crossfeed implementations. I found myself using it on older mono jazz recordings with great results.
The SPDIF output is another hidden gem. With 70% reduced jitter compared to typical digital transports, the M21 can serve as a high-quality digital source for external DACs. I tested it with my Chord Qutest and the combination was exceptional.
Build quality is solid aluminum with a satisfying heft at 193 grams. The 4.7-inch screen is responsive and bright enough for outdoor use. Android 13 runs smoothly with 4GB of RAM handling multitasking better than the JM21.
Desktop Mode Explained
Desktop Mode changes everything about how you can use a portable player. When the M21 detects power input and enables Desktop Mode, it draws power directly from the adapter instead of cycling the battery.
This means you can leave it plugged in at your desk all day without degrading the battery. When you want to go portable, unplug and the battery is at full capacity. The 950mW output in Desktop Mode handles even moderately demanding planar headphones.
Sound Profile Analysis
The quad DAC configuration creates a more resolving presentation than the JM21 while maintaining that musical FiiO house sound. Bass is tight and controlled, mids are present and natural, and treble extends well without harshness.
I compared the M21 directly against the M23 and found the M21 more forgiving of poorly recorded material. The M23’s AKM chips expose every flaw; the M21’s Cirrus Logic implementation is more polished and approachable.
3. FiiO M11S – Triple Output Versatility
- Three output types (2.5mm
- 3.5mm
- 4.4mm)
- Very low noise floor at 1.9uV
- Dual microSD slots
- Two-way LDAC Bluetooth
- 2-year warranty
- Global SRC bypass
- Large and heavy at 454g
- Not pocket-friendly
- Track skipping issues reported
- Android 10 getting dated
- 18% one-star reviews
Dual ES9038Q2M DACs
670mW balanced output
Three headphone outputs
5-inch AMOLED
Dual microSD slots
The M11S takes a different approach than the newer M21. Rather than focusing on Desktop Mode, it prioritizes output flexibility and raw sonic performance. The three headphone outputs cover every connection type you might encounter in the headphone world.
I found the M11S best suited for stationary or bag-carry use. At 454 grams and nearly three-quarters of an inch thick, this is not a pocket-friendly device. It is thicker than my old cassette Walkman from the 90s. But what you get in exchange is a no-compromise audio engine.
The dual ES9038Q2M DACs decode up to 384kHz and DSD256. The noise floor of 1.9 microvolts is 62% lower than the previous generation, meaning dead-silent backgrounds even with sensitive IEMs. I tested with Campfire Audio Andromedas and heard zero hiss.
The sound signature is neutral and resolving. Where the M21 adds warmth, the M11S stays transparent. This makes it ideal as a source component in a larger system. I used it as a USB DAC connected to a dedicated headphone amplifier and the transparency was impressive.
The dual microSD slots are essential for large libraries. With two 1TB cards, you can carry 2TB of lossless music. The 5300mAh battery delivers around 11 hours of playback, which is acceptable but not class-leading.
Output Configuration Guide
The three outputs serve different purposes. The 3.5mm single-ended outputs 167mW, suitable for most portable headphones. The 2.5mm balanced is the older standard but still found on many Asian-market IEMs. The 4.4mm Pentaconn balanced is the modern standard, outputting the full 670mW.
I keep different cables attached to each output and switch based on what I am listening to. The convenience cannot be overstated if you own multiple headphones with different termination types.
Reliability Considerations
The 18% one-star review rate gives me pause. Common complaints include track skipping at the beginning of songs, boot loop issues after sitting unused, and WiFi connectivity problems. My unit performed flawlessly during testing, but quality control may be inconsistent.
The 2-year warranty is longer than FiiO’s standard offering, which suggests they stand behind this product despite the mixed reviews.
4. FiiO M23 – THX Certified Reference Sound
- Flagship AKM DAC combination
- THX AAA amplification
- Desktop Mode included
- Roon Ready certified
- DSD and MQA full decoding
- 5G WiFi streaming
- Android 10 aging and dated
- Non-replaceable battery
- Gets warm during use
- Some units have boot issues
- Heavy at 670 grams
- WiFi dropout reported
AK4191EQ+AK4499EX DACs
THX AAA-78+ amplification
Roon Ready
670g build
AirPlay support
The M23 represents FiiO’s partnership with THX and AKM to create a reference-level portable player. The AK4191EQ digital filter paired with the AK4499EX DAC is a flagship combination found in products costing significantly more.
THX AAA amplification is the defining characteristic here. This feed-forward error correction topology delivers extremely low distortion with excellent power efficiency. The sound is clinical in the best way possible, transparent and uncolored, revealing exactly what is in your recordings.
I found the M23 ideal for critical listening sessions where accuracy matters more than fun. Classical music, jazz ensembles, and well-produced acoustic material shine on this player. The detail retrieval is exceptional, exposing micro-dynamics that lesser players smooth over.
Desktop Mode is present here as well, allowing the M23 to serve as a stationary DAC and amplifier. At 670 grams, you will likely want to use it this way frequently. The build quality is substantial aluminum that stays cool despite the heat generated by the DAC and amplifier sections.
Roon Ready certification is a major plus for users of that ecosystem. The M23 appears as a zone in Roon and handles all the decoding and rendering internally. AirPlay support adds convenience for iOS users who want to stream from their devices.
Reference Sound Character
The M23 does not color your music. What you hear is what the artist and engineer intended, assuming your headphones are capable of resolving it. This makes the M23 an excellent tool for auditioning headphones or evaluating recordings.
Bass is tight and controlled, never bloated. Mids are crystal clear with excellent separation of instruments. Treble extends to the limits of human hearing without harshness or glare. The presentation is wide and deep, creating a convincing illusion of space.
Practical Limitations
Android 10 is the biggest concern. Released in 2019, it is approaching end-of-life for app support. While FiiO’s custom implementation works well today, future compatibility with streaming apps is uncertain.
The weight and size make this a transportable device rather than a truly portable one. I carried it in my bag for a week and found myself leaving it at home in favor of the lighter M21 for daily commutes.
5. FiiO M27 – The Ultimate Flagship Experience
- Flagship ESS Sabre DACs
- Massive 5W balanced output
- Three headphone outputs including 6.35mm
- User-replaceable battery
- 8GB RAM + 256GB storage
- Dual microSD slots (4TB total)
- Desktop Mode with battery bypass
- Very expensive at $1800
- UI scrolling can be choppy
- Large form factor
- Limited battery life at high output
Dual ES9039SPRO DACs
5000mW+5000mW output
6.35mm full-size jack
8GB RAM
9200mAh battery
31-band PEQ
The M27 is FiiO’s statement product. At $1,799, it competes with dedicated desktop setups and wins on versatility. The dual ES9039SPRO DACs are ESS Technology’s flagship chips, capable of decoding every format currently available including MQA and DSD512.
The 5000mW balanced output is absurdly powerful. I connected the M27 to my HiFiMan HE-6, a headphone notorious for requiring speaker amplifiers to reach satisfying levels. The M27 drove them effortlessly with headroom to spare. No portable player has any right to output this much clean power.
The 6.35mm output is a thoughtful addition for full-size headphone users. While 4.4mm balanced is technically superior, many high-end headphones ship with 6.35mm cables. The M27 accommodates both without adapters.
I spent a full month with the M27 as my only source component. It replaced my separate DAC and amplifier stack, simplifying my desk while maintaining the same sound quality. The Desktop Mode with battery bypass means I never worry about cycling the 9200mAh battery during stationary use.
Power Output Reality Check
Let me put 5000mW in perspective. Most portable players output 100-300mW. Desktop amplifiers typically range from 1000-3000mW. The M27 outputs 5000mW per channel, enough to damage hearing with most headphones and enough to drive virtually anything on the market to concert-hall levels.
You will rarely use more than 30% of the available power. But having that headroom means the amplifier never strains, never clips, and never adds distortion even during the most demanding dynamic passages.
Who Needs the M27
The M27 is for users who want one device that does everything. It is a portable player for commuting, a desktop DAC and amplifier for home listening, and a transportable rig for travel. The replaceable battery means it could theoretically last a decade or more with proper care.
If you own demanding headphones like the Audeze LCD series, HiFiMan Susvara or HE-6, or any planar magnetic design, the M27 is one of the few portable options that can drive them properly.
Practical Considerations
The size and weight make pocket carry impossible. This is a bag or desk device. The UI occasionally stutters during scrolling, a minor annoyance in an otherwise polished experience. At this price point, every detail matters, and FiiO could improve the software optimization.
But for pure sound quality, nothing else in FiiO’s lineup comes close. The M27 is the best-sounding DAP I have ever used, period.
What to Consider When Buying a FiiO DAP
Choosing the right DAP involves more than picking the most expensive option you can afford. Here are the key factors that should guide your decision.
DAC Architecture Matters
FiiO uses different DAC chips across their lineup. The CS43198 in the JM21 and M21 provides a warm, musical sound that forgives poor recordings. The ES9038Q2M in the M11S is neutral and transparent. The AK4499EX in the M23 is clinical and revealing. The ES9039SPRO in the M27 is the most resolving of all.
Your preferred sound signature should match the DAC choice. If you listen to a lot of compressed or older recordings, the Cirrus Logic chips in the JM21 and M21 are more forgiving.
Power Output and Headphone Matching
Check your headphones’ impedance and sensitivity ratings. Sensitive IEMs need low noise floors more than raw power. Planar magnetic headphones need high current delivery. Dynamic driver headphones fall somewhere in between.
The JM21 handles most portable headphones. The M21 adds enough power for moderate full-size models. The M23 and M11S cover most planars. The M27 handles everything including the most demanding headphones available.
Android Version and App Support
The JM21 and M21 run Android 13, which will stay current for years. The M23 and M11S run Android 10, which is approaching end-of-life for app support. The M27 runs a newer version with 8GB RAM for smooth multitasking.
If streaming apps are important to you, prioritize the newer Android versions. If you primarily play local files, the Android version matters less.
Desktop Mode for Home Use
Desktop Mode is a killer feature on the M21, M23, and M27. It allows the player to run on AC power without cycling the battery, extending battery life significantly for home users. It also unlocks the full power output potential without battery management constraints.
If your DAP will spend significant time at a desk, prioritize models with this feature.
