The FiiO M27 is not an ordinary portable music player. You notice that even before a single note is played. This is a large, heavy and exceptionally complete device, clearly designed for music lovers who do not want to compromise on sound quality, whether they are on the move, at the office or listening at home. The M27 is available in black and titanium and positions itself as the absolute flagship among FiiO’s portable players.

While many portable players mainly focus on convenience, compactness and battery life, FiiO takes a different route with the M27: maximum sound quality, plenty of power, extensive connectivity and an interface that finally feels as modern as using a smartphone. The M27 is therefore not necessarily a player for everyone, but it is certainly a player for serious listeners.

First impression: luxurious, large and purpose-built

The FiiO M27 immediately makes it clear that it plays in a different class. The housing feels robust, beautifully finished and extremely solid. In black, it looks businesslike and technical, while the titanium version appears a little more exclusive and luxurious. That titanium version is also heavier, which enhances the premium feel, but also makes it clear that this is not a player you casually slip into your trouser pocket.

That is important to mention honestly: the M27 is portable, but it is not really pocket-friendly. It is better to see it as a transportable high-end player. A device you carry in a bag, place on your desk, use next to your listening chair or integrate into a compact headphone setup. If you are looking for an ultra-light player for sports or walks, this is not the right choice. If you are looking for a compact desktop system in one device, it becomes surprisingly convincing.

The controls are a strong point. The large touchscreen, physical buttons, volume knob and clearly arranged connections ensure that the M27 not only looks impressive, but also feels logical and pleasant to use. FiiO has clearly understood that a flagship should not only sound good, but also be enjoyable in daily use.

Technology: flagship level in every respect

Inside, the FiiO M27 is impressively specified. The player uses dual ESS ES9039SPRO DACs, a powerful Qualcomm Dragonwing QCS6490 processor, 8 GB of RAM and 256 GB of internal storage. Thanks to the two microSD card slots, storage can be expanded up to 4 TB. For users with large hi-res music libraries, that is a major advantage.

In terms of file playback, the M27 is also extremely complete. PCM up to 32-bit / 768 kHz and native DSD512 are supported. In addition, it offers Android streaming, Bluetooth with modern codecs such as LDAC and aptX Lossless, USB DAC functionality, AirPlay, coaxial and optical options, plus various listening modes. The M27 is therefore not just a music player, but also a DAC, streamer, Bluetooth receiver, digital source and headphone amplifier in one.

A particularly strong feature is its power output. Through the 4.4 mm balanced output, the M27 can deliver up to 5000 mW per channel in Ultra High Gain mode. That is exceptional for a device that is still sold as a portable player. As a result, it can drive not only sensitive in-ear monitors, but also many demanding over-ear headphones with real authority.

Sound: neutral, powerful and exceptionally open

The FiiO M27 does not sound warm, soft or overly romantic. This is a player with a clear reference-style tuning: clean, spacious, powerful and very controlled. It does not try to make music sound prettier than it is, but instead reveals what is actually present in the recording.

With good recordings, the result is impressive. The soundstage is wide and deep, instruments are clearly separated from one another, and details come forward easily without sounding forced. Especially with well-recorded hi-res files, the M27 shows why it belongs in the top class. Voices gain texture, string instruments become more tangible and percussion sounds tight, fast and precise.

The bass is powerful, but not exaggerated. The low-end has grip, speed and control. That makes the M27 especially suitable for headphones that need a little extra authority. Even with complex music, the bass remains well organized and the sound image does not become muddy.

The midrange is clear and open. Voices sound direct and natural, without excessive warmth. Acoustic instruments benefit from the high resolution and quiet background. The player makes subtle differences in recording quality, microdynamics and tonal character clearly audible.

The treble is detailed and airy, but not aggressive as long as the recording is good. This is also where the M27 shows its critical side: poor masters, heavy compression or low streaming quality are not politely smoothed over. The player is honest. That is wonderful with good files, but less forgiving with weaker sources.

Power and control: almost desktop-grade

The biggest distinction of the FiiO M27 may well be the combination of portability and power. Many DAPs sound good with sensitive in-ears, but lose control once larger or more difficult headphones are connected. The M27 suffers from that far less quickly.

With its high output power, multiple gain levels and desktop mode, it feels more like a compact headphone amplifier with an integrated player than a traditional portable DAP. Especially through the 4.4 mm balanced output, the player comes fully into its own. The soundstage becomes larger, dynamics increase and headphones gain noticeably more grip.

This makes the M27 interesting for users who want one device for several applications. At home on mains power in desktop mode, on the move with local files, connected to a laptop as a USB DAC or used as a source for a hi-fi system: the M27 can handle it all.

Android and usability: finally fast enough

A common criticism of high-end DAPs is that they can sound excellent, but feel slow or outdated in operation. The FiiO M27 does noticeably better. Thanks to the powerful processor and 8 GB of RAM, Android 13 feels smooth and responsive. Apps open quickly, scrolling is fluid and large music libraries are faster to search than on older FiiO players.

The presence of Google Play makes everyday use practical. Streaming services such as Qobuz, Tidal, Apple Music, Spotify or Deezer can simply be installed. Those who prefer focused listening can use Pure Music Mode. This turns the M27 more into a traditional audio player, without distractions from other apps.

The 31-band PEQ is another important plus point. It allows the sound to be adjusted precisely to a specific headphone or personal preference. For users with multiple headphones, this is especially valuable. The M27 is neutral and transparent by nature, but offers enough tools to fine-tune it to your own taste.

Who is the FiiO M27 for?

The FiiO M27 is ideal for demanding listeners looking for a very complete all-in-one solution. It suits someone with a large digital music library, high-quality headphones and the desire to use one device as a player, DAC, streamer and headphone amplifier.

It is also surprisingly attractive for desktop use. Place it in the supplied stand, connect it to mains power, use desktop mode and the M27 turns into a serious compact listening solution. That makes it interesting for people who do not want to stack separate DACs, streamers and headphone amplifiers, but still expect high-level performance.

For purely mobile use, it is less obvious. It is large, heavy and powerful, but not discreet. It may fit in a jacket pocket, but not really in a trouser pocket. Those who mainly listen on the move with small in-ears will probably find a lighter FiiO player more practical.

Black or titanium?

The black version is the more understated choice. It looks professional, clean and suits users who prefer a less eye-catching player. The titanium version feels more exclusive and luxurious, but is also heavier. If you mainly use the M27 at home, in the office or in a fixed listening spot, that extra weight will be less of an issue. If you take it with you more often, black is probably the more practical choice.

Both versions share the same character: serious, robust and high-end. The choice is therefore mainly a matter of appearance, weight and personal preference.

Drawbacks

The FiiO M27 is impressive, but not perfect. Its size and weight are the most important drawbacks. This is not a player you buy because it is especially small and easy to carry. It also gets warm during intensive use, especially when a lot of power is required. FiiO has taken this into account with cooling, desktop mode and accessories, but it remains something to be aware of.

In addition, the neutral and highly transparent sound will not be ideal for everyone. Those looking for a warm, soft or very forgiving player may find the M27 a little too direct. It reveals quality, but also weaknesses. Low-bitrate streaming, mediocre recordings or sharply mastered music are not made prettier than they are.

Finally, the price is substantial. In return you get a lot of technology, power and versatility, but this remains a player for the serious listener.

Conclusion: an impressive flagship with a clear character

The FiiO M27 is one of the most complete and powerful digital audio players of its time. It combines a reference-style sound with enormous power, modern Android operation, excellent connectivity and build quality worthy of a flagship.

Its greatest strength is that it blurs boundaries. It is portable, yet it sounds and functions almost like a desktop system. It is a music player, but also a DAC, streamer, Bluetooth receiver and headphone amplifier. It is technically impressive, yet remains accessible in use.

The M27 is not the right choice for those who mainly want something small, light and simple. But for anyone who wants to get the best out of high-quality headphones and is looking for an all-in-one player that convinces both at home and on the move, the FiiO M27 is a particularly strong choice.

In black, it is stylish and businesslike. In titanium, it is more luxurious and eye-catching. In both cases, the message is the same: the FiiO M27 is not an ordinary DAP, but a serious high-end listening instrument for those who want to experience their digital music collection at the highest level.
