Mission impossible: HiFiMAN launch $399 SuperMini portable player


What do we want from a digital audio player (DAP)? Great sound – that’s a given; it’s why we eschew our smartphones in favour of a secondary, superior sounding device. Making the DAP choice trickier is category’s ground, forever shifting beneath our feet. Back in 2013, we had but a handful of options from which to choose. Three years later and it’s a minefield of possibilities.

On the twelve hour flight from Sydney to Los Angeles, the average model from category leader Astell&Kern won’t last the distance. Neither will it accommodate user-installable apps via the Google Play store.

To tick both of those boxes we look to Sony’s NW-ZX2 which is, for all intents and purposes, is an Android smartphone, its telecommunication smarts replaced by better-sounding audio circuitry.

Rival units from Onkyo, Pioneer, FiiO and Acoustic Research offer similar Android app-based functionality – crucial for Mixcloud, Soundcloud, Tidal, Spotify, Pandora et al. Yet none can match the Sony ZX2 on battery life – it offers a whopping 33 hours when playing back hi-res content, even longer with Redbook PCM or MP3. This often-overlooked specification matters to trans-Atlantic and trans-Pacific journeymen.

However, with this year’s introduction of AudioQuest’s DragonFly Black and Red, one might legitimately ask: why factor streaming services into a DAP purchase when a terrific sounding in-line DAC/headphone amplifier can be added to an existing smartphone for US$99/US$199?

It’s not all sunshine and roses in Android and Apple Land. Where the average smartphone comes up short is on 1) FLAC file loading – it can be fiddly; and 2) hi-res file compatibility – it isn’t baked into either OS.

Perhaps all we need from a DAP in 2016 is drag n’ drop file loading, perhaps via an in-built microSD card slot, and the ability to decode up to 24bit/192kHz PCM / DSD, all without a major hit to runtime between charges.

Ditching the full-size screen not only conserves go juice but makes it easier for those who prefer to strap-on an external DAC/amplifier.


So – say Ni Hao to HiFiMAN’s SuperMini which meets our microSD card-loading and hi-res rocking requirements but ices them with four op-amps per output channel for 4.2V “peak to peak” power (320mW) into 32 Ohms. According to the manufacturer, that’s more than sufficient for HiFiMAN’s own 400S and 400i planars and Sennheiser’s HD650/600 dynamics. Single-ended and balanced outputs present at the base of the unit.

Battery life on this pocket rocket is rated at 22 hours, made possible by HiFiMAN founder and CEO Dr Fang Bian’s choice of silicon. He’s gone for a single chip that combines microcontroller and D/A converter but crucially he has tweaked its firmware for a MUCH better sound.

Such tweaking is something that Dr Fang, a keen soccer player and joke teller, referred to as Mission Impossible when I first encountered his new palm-sized portable at CanJam SoCal back in March of this year (which provides the context for the majority of this post’s photos).

For this commentator, the SuperMini was more of a HiFiMAN hit than their tubed up statement Shangri-La electrostatic rig that commanded long wait times at the opposite end of the table.

Dr. Fang Bian shows off his new SuperMini DAP at CanJam SoCal 2016.

At CanJam, the SuperMini on display was just a prototype, a work in progress with the menu system and OSD graphics for its OLED display still be finalised.

Gapless playback has since been confirmed by HiFiMAN’s Facebook manager as being present and correct. You can’t say that about the similarly form-factored XDuoo X3. [see update below]

Six months later and the SuperMini is now shipping for a most agreeable US$399. Included in the deal is a pair of “special balanced model” IEMs. Value with a capital V. This DAP’s trimmed and toned form factor (104mm x 45mm x 8.5mm and 70g) won’t see you walking with a limp and with a dongle DAC sprucing up streaming on one’s phone, the HiFIMAN SuperMini could be more than anyone might need to plug the hi-res hole. A review unit has been requested.

One final thought: prefer a press release-based news announcement? The Absolute Sound has you covered here.

UPDATE 7th September: Gapless playback has been shelved at the 11th hour and for the foreseeable future.

  1. and has no quality wifi for streaming, esp given how popular streaming is becoming?
    love the small size but will keep my lowly ipod touch 6 with a dragonfly red to cover more bases.
    i just don’t understand DAP makers that don’t include streaming capabilities.

  2. “Included in the deal is a pair of “special balanced model” IEMs.”

    They’re being a little vague about this part of it; is this shipping with the RE-600s or is this a new pair of IEMs? Seems like this would be a natural pairing for the 600s as they are balanced, and that would be a HELL of a value if they came together.

  3. Would it be too much of an ask to include wifi streaming? Isn’t offline DAPs DOA already? Is it a big miss on Hifiman’s part or a deliberate decision? It is okay if it lasts 12 hours with the streaming hi-res workload than offline.

  4. No hint of the chipset that they are deploying … I am guessing the Amlogic s905x or 912 which are the first wave of Android focused Quad core Cortex chips to integrate a high-res DAC. Thumbs up to HiFiMan achievement in this sector…

  5. A nice, little surprise from HiFiMan. Haven’t read anything about on-board memory, though. Is there some, or is it solely through the microSD card?

  6. John, I want to share an email that I sent to Hifiman customer service today regarding my experience with the Supermini so far and it has not been positive. I hope you have a better outcome with your review unit.

    “I bought a hifiman supermini from Penon Audio and it arrived two days ago here in the US. I have had the following problems…

    1)The instructions are in chinese. After I asked hifiman about this, an english version was posted on your website.
    2)Although the owner’s manual and the hifiman website say the product supports AIFF 24bit/196kHz files, this is not true. I learned this after my purchase and after two contacts to hifiman customer service. Apparently the answer is that it will play only 16bit AIFF files but 24bit files in other formats though those were not specified.
    3)Some of my FLAC 24bit/96kHz music files purchased from HDTracks play ok and some do not play at all and are identified as “not supported” by the supermini. All of these files play perfectly on my mac mini based system using Pure Music and stream perfectly via Roon.
    4)None of the FLAC files that do play display any album or artist information or album artwork. They are just a long list of songs making it impossible to use the genre, artist or song sorting that seems to be available based upon the menu choices on the supermini. When played on my mac mini system through either Pure Music or streaming via Roon, ALL the files display genre, artist, album and artwork just fine.
    5)There is a permanent white horizontal line across the top third of my screen when the unit is powered on. Penon told me that was because I was trying to play 24bit AIFF files. That is not true because the white line is there with all my FLAC files as well.

    This product seems to offer only some of what is advertised and the support from hifiman comes only after a 24 hour turnaround and only by email.

    Penon has agreed to accept the return of my unit but I need to pay the shipping back to Hong Kong.

    Again, I hope your experience will be different.
