But how do you find your way through this large catalog? This comparison guide offers a clear overview to help you choose the model that best suits your needs and budget.

FiiO: the portable hi-fi revolution

Founded almost 20 years ago, FiiO rapidly established itself as a major player in portable hi-fi. The Chinese brand first made a name for itself with its high-performance headphone amplifiers, before extending its expertise to the HD digital audio player market. Very early on, FiiO realized that there was a real demand for a credible alternative to smartphones for anyone who wanted to enjoy hi-fi quality sound with their library of high-resolution files.

The brand’s philosophy is clear: to offer portable players capable of playing virtually all current audio formats (from FLAC to high-resolution DSD) with a large internal and expandable storage capacity, so you can take your entire music library with you. Added to this is a large touchscreen for smooth navigation through the Android interface that provides access to streaming services and, above all, advanced sound customization possibilities thanks to advanced parametric equalizers for fine-tuning the signature according to the headphones used or your listening preferences. Amplification completes the package, with power stages capable of efficiently powering both sensitive in-ear monitors and more demanding headphones. The result is a truly modern environment, similar to that of a smartphone, but optimized for high-resolution audio. Over the generations, FiiO has structured its offer in a coherent way, with compact entry-level models, versatile DAPs designed for both traveling and home use, and powerful DAPs capable of taming the most demanding headphones.

FiiO JM21: the essentials at a low price

At the entry-level of the range, the FiiO JM21 presents itself as a compact, affordable audiophile player, designed to offer a real alternative to smartphones in terms of sound quality.

In addition to streaming, it can read local files stored in its 32GB internal memory or on a microSD card (up to 2TB).

The JM21 is particularly well-suited to mobile users who want to take their music experience to the next level, with sound that’s more detailed, better structured and more dynamic than that of a telephone. Its extensive compatibility with various Hi-Res formats, comfortable 12.5-hour battery life, and compact, lightweight chassis (just 156g) make it an excellent entry point into the brand’s world.

FiiO M21: first steps into the audiophile world

Priced at €329, the FiiO M21 DAP is the bridge between the very affordable JM21 and the more ambitious FiiO M33 R2R. With this model, the brand intends to make technologies from its superior references more accessible while maintaining a compact format and an attractive price. It also introduces a desktop mode to boost performance when powered via USB, making it equally suited to nomadic or sedentary use, on a desk or alongside the living-room hi-fi system, thanks to its line outputs.

The move up in range is justified by the fully balanced architecture, with four Cirrus Logic CS43198 DACs for even more precise signal conversion. This technical choice enables it to support PCM streams up to 32-bit/384kHz, as well as native DSD256. The 3.5mm mini-jack and 4.4mm balanced jack headphone outputs benefit from powerful amplification, capable of delivering up to 950mW per channel, enabling association with a wide variety of headphones and earbuds. Running on Android, the FiiO M21 offers direct access to the main streaming platforms and a smooth interface, similar to that of a contemporary smartphone. A solution designed for discerning music lovers who want to combine audiophile performance with a controlled budget.

FiiO M33 R2R: a DAP with a passive DAC

Successor to the FiiO M23, the FiiO M33 R2R DAP released this year marks a technological breakthrough in the range. Where the majority of portable players rely on DACs with a Delta-Sigma architecture, this model adopts an R2R conversion stage, made up of a network of 192 resistors. This enables it to perform entirely passive conversion of streams up to 32-bit/768kHz and DSD512 for a more organic sound reproduction, with harmonic continuity particularly attractive on vocals and acoustic instruments. It will appeal to fans of analog sound thanks to its operating principle, which is very similar to that of a modern, connected device.

In addition to its R2R conversion, the FiiO M33 R2R DAP features 1,100mW amplification capable of driving demanding headphones via the balanced 4.4mm jack or unbalanced 3.5mm mini-jack output. Its Android 13 interface with 8GB of RAM ensures smooth navigation through the various streaming apps, a vast local library (128GB internal storage expandable via a micro SD card up to 2TB) or audio files shared via DLNA protocol on the home network. What’s more, Bluetooth 5.0 connectivity with support for aptX, aptX HD, LDAC and LHDC codecs enables music to be both received and streamed to headphones or connected speakers. Last but not least, management is further enhanced by a large, bright and high-contrast 5.5″ touchscreen, with a resolution of 1080 x 2160 pixels.

FiiO M15S: the best of FiiO’s expertise for under €1,000

Successor to the acclaimed FiiO M15, the FiiO M15S DAP inherits an 8-channel ES9038Pro DAC, borrowed from the ultimate FiiO M17, while offering a solution under the €1,000 mark. It supports the majority of audio formats, including PCM up to 32-bit/768kHz and DSD files up to DSD 512 (DSD 22.1 MHz). It is also the only model of the brand, along with the previous M17, to offer a balanced 2.5mm jack headphone output, in addition to the balanced 4.4mm jack and unbalanced 3.5mm mini-jack outputs. Coupled with a high power rating of up to 1,200mW, this triple output efficiently powers any headphones or earbuds.

The FiiO M15S is aimed at discerning listeners who want to take portable sound reproduction to the next level. Its power reserve enables it to serenely power headphones with a reputation of being difficult. While the FiiO M33 R2R focuses on a full, organic reproduction, the FiiO M15S will appeal to lovers of neutrality and transparency. It’s the perfect choice for those looking for a high-end portable solution capable of combining technical performance, user comfort, and a hi-fi Hi-Res reproduction.

FiiO M27: the ultimate FiiO DAP

Positioned at the top of the range, the FiiO M27 DAP offers the ultimate solution, equally at home in the pocket of a music lover on the move or on a desk. To this end, its dedicated desktop mode can be activated when the device is mains-powered to boost amplification power and bypass the battery, while its included ventilated stand enables optimal use over extended periods. It then holds its own against real sedentary amplifiers, with a colossal power output of 5,000mW into 32Ω coupled with a triple output: 4.4mm jack, 3.5mm jack and even a 6.35mm jack output for connecting any hi-fi headphones. The move upmarket is also reflected in the connectivity, with a separate coaxial and optical output, in addition to the usual line outputs. It can thus become a fully-fledged source in any existing hi-fi system, whether for streaming or local file playback. Its storage capacity is extended to 256GB (the largest on a FiiO DAP) and expandable up to 4TB (two micro SD card slots with a maximum capacity of 2TB per card). The screen is also the largest ever seen on a FiiO portable player, with a 5.99-inch (15.2 cm) panel offering exemplary responsiveness.

Digital-to-analog conversion is carried out by the latest generation of ESS Sabre ES9039SPRO DACs, mounted in a balanced configuration for separate channel processing. This limits interference, resulting in a better signal-to-noise ratio and finer detail. The data is clocked by a powerful FPGA processor and a dual femtosecond clock to limit jitter and offer very high listening precision. The FiiO M27 is therefore able to make the most of Hi-Res files up to 32-bit/768kHz and DSD512. As the most versatile of all FiiO DAPs, the M27 comes with a removable battery, guaranteeing a long-lasting device that will accompany the user for many years to come, whether on the move, in the office, or on the hi-fi system in the living room.

With its range of DAPs, FiiO demonstrates impressive expertise in portable audio, capable of satisfying both curious music lovers and the most demanding audiophiles. From the accessible and compact JM21 to the M27, conceived as a true hybrid source for portable and high-fidelity use, each model is part of a logical technical progression adapted to precise uses. The brand manages to combine high audio performance, a modern Android software interface, full streaming compatibility, and amplifier stages capable of powering demanding headphones without losing sight of ergonomics and portability.

The model you choose will depend above all on how you want to listen to your music: a simple upgrade compared to a smartphone, a versatile solution for everyday streaming, a more organic R2R architecture, or a true hybrid amp capable of powering high-end headphones on a desktop.
