“Low-cost” with flagship options

The FiiO M21’s checklist of {hardware} and software program options is in depth. This might very simply be a few-page-long evaluation to cowl each {hardware} innovation and use case. There are DAPs with related options that value tons of of {dollars} extra. Within the curiosity of constructing this evaluation accessible to music fanatics and the “audiophile curious,” I’ll maintain this as accessible as potential.

Unbox the FiiO M21, and also you’re greeted by a beveled anti-glare frosted glass again, textured aluminum alloy physique, and a handsome 4.7-inch 750×1334 IPS show that comes with a display protector already put in, all wrapped within the included, color-matched silicone case. The unit seems to have a really sturdy construct when considered within the field.

Eradicating the system from the packaging, it has an important in-hand really feel, because of the beveled edges. Along with the included silicone case, FiiO despatched a PU case to take a look at, which is a pleasant contact, and with extra instances out there from them, together with one which makes your DAP appear like a retro Walkman, you will have loads of choices for protecting, trendy carry. Wanting across the system, you will discover a 3.5mm single-ended and 4.4mm Balanced output on prime. Each assist line out, with the three.5mm additionally supporting coaxial output.

It is what’s on the within that counts

Energy and connectivity to spare

This part might go on for pages, labeling and explaining every part contained in the FiiO M21. You get Qualcomm’s Snapdragon 680 processor that runs Android 13 and any apps you obtain, fairly capably. Plus, with an eight-core processor operating as much as 2.4GHz with 4GB of RAM, it is highly effective sufficient so that you can hearken to lossless music information on excessive achieve and surf the net, or crap-post memes concurrently, if that is your factor.

With that processor, you will additionally get Bluetooth 5.0 with assist for aptX HD, LDAC, and LHDC, together with the fundamental codecs. The chipset additionally has assist for each 2.4GHz and 5GHz Wi-Fi that helps DLNA, Airplay, Wi-Fi music switch, and is Roon-ready.

For the total checklist of energy outputs for that, see the spec chart.

FiiO M21 in a phrase: Clear

Impartial, with wonderful element retrieval

Let’s get into what you got here right here for: the listening and day by day use expertise. I examined the FiiO M21 with a couple of headphones, IEMs, and TWS earbuds:

General, the FiiO M21 is a splendidly clear expertise that brings audio to life with vivid element and nuance. Actively listening utilizing the 4.4mm Balanced port and medium achieve with Sennheiser’s analytical flagship $1500 IE900 IEMs, I used to be in a position to hear particulars just like the fingering of saxophone keys as they have been depressed earlier than the saxophonist blows the notes on Charles Mingus’ chaotic Jazz romp, Moanin’.

The transparency and element retrieval of the M21 with the analytical IE900 had a gorgeous synergy, however that transparency also can imply fatiguing treble. Listening to Artwork Blakey’s tackle Moanin’ these harsh horns could be fairly fatiguing at particular moments within the composition.

Lively listening utilizing Campfire Audio’s heat Mammoth IEM’s was a deal with — I listened utilizing each 3.5 mm and 4.4 mm jacks, and the quantity of readability, transparency, and nuance was excellent. The stereo imaging was merely passable, however this was extra because of the Mammoths themselves than the M21’s output. With this pairing, you get a robust sense of the intimate soundstage, and you are going to choose up on issues like room tone and sound reverberation within the studio recordings. If it is a reside recording, these little particulars actually come via and provides a reside really feel to the music.

With every part I threw on the FiiO M21, my main takeaway is that the extent of transparency and element retrieval is elegant. It’s a “colder” hear than some DAPs in that the underside finish heat is not hyped, so you are going to get the music simply as recorded. Some may name it a bit flat, however I can completely let you know that is dependent upon how a music was mastered and the headphones/IEMs/TWS earbuds you pair the DAP with.

For instance, The Roots’ Do You Need Extra?!?!?! is mastered with deep bass that had pleasant extension and presence with all listening gear I related to. Skrillex’s Supersonic (my existence) nonetheless had its deep, darkish rumble, however it simply wasn’t as hyped because it comes off when performed from a DAP or DAC with V-curve tuning. I all the time inform folks that your headphones are extra necessary than your DAP/DAC, and that’s equally true within the case of the M21.

Working example: listening to these songs with the wonderful Noble Rex 5 TWS earbuds imbues these songs and others with extra weight, extra drama, extra of that soul-stirring vibration with none want for the PEQ, which, by the way in which, doesn’t work with Bluetooth earbuds.

The good information is that, with this DAP, you get wonderful choices for shaping the sound extra to your liking via the sturdy ten-band parametric EQ. In case you have the means to decide on totally different listening gear primarily based in your temper, the FiiO M21’s sound high quality is so good which you can forgo the PEQ altogether and simply use the headphones/IEMs/TWS earbuds that match your required sound signature. Need extra hype within the lows? Join them to these headphones with the menacingly darkish bass and sub-bass response. Rinse and repeat, throughout the frequency spectrum.

Battery life

And different experiences

The inclusion of a devoted charging port that helps quick charging is a delight right here. In half-hour, I charged the DAP from 53% to full. It should take roughly 1.5 hours to cost from 0% to full utilizing the devoted port and a PD3.0 charger. For analog or digital playback, I discovered roughly one hour of play through the 4.4mm port with medium achieve and display at max brightness drained roughly 20% of the battery.

Having each 2.4GHz and 5GHz WiFi makes streaming easy. The M21 connects shortly, and throughput is quick and constant. Bluetooth high quality has been surprisingly strong, even with formidable atmospheric situations. As a lot as I like Noble’s Rex 5 TWS earbuds, their LDAC connections to a number of gadgets I’ve examined them with has been finicky. The M21 has been the exception, with the Rex 5 related utilizing the Finest Effort (Adaptive Bit Price) playback high quality possibility, having no points with sign breakup. In my testing utilizing Bluetooth, I discovered that one hour of play utilizing LDAC with the audio round 70 steps of 125, drained the battery by 10%.

Relying on my connection kind, quantity stage, and music style, I discovered myself getting anyplace from 10 to fifteen hours of playback. You will get extra stamina out of the three.5mm port, however the very best audio high quality comes from that 4.4mm port. Regardless, I used to be by no means involved about battery life with the FiiO M21’s quick charging capabilities or the devoted energy port on faucet.

When you do not utterly energy down the system after use, my expertise with battery standby was a 6% drain over 22 hours.

What might use enchancment

Not quite a bit at this worth

With strong sound high quality, an intensive characteristic checklist, and attractiveness there is not quite a bit FiiO might do to improve the expertise at this worth. Because the M21 is operating a personalized model of Android 13 with a Snapdragon chipset, I would prefer to see computerized brightness added to enhance outside use underneath these shiny California skies, in addition to aptX Adaptive and LE Bluetooth with Auracast assist.

As time goes on, I believe Auracast will probably be an necessary characteristic for DAPs to have.

Must you purchase the FiiO M21 digital audio participant?

There may be strong competitors for the FiiO M21 within the type of the HiBy R4, Shanling M3 Plus, Astell&Kern Activo P1, and iBasso DX180. For the worth, the M21 isn’t solely some of the highly effective, however the very best worth of the bunch. The one issue that will trigger me to think about any of these towards FiiO is iBasso’s DX180 and its user-replaceable battery. With the ability to pop a brand new battery in will improve the helpful lifetime of the DX180, however that is it.

Personally, I would say that at $329, the FiiO M21 is without doubt one of the greatest entry-level DAPs available on the market right now, so I can completely suggest it.
