HiBy R3 Pro
HiBy R3 Pro
The R3 Pro is a steady evolution of an already proven platform, the excellent R3. The main improvements are in the output power and overall tuning. The tone is now a shade more natural, smoother, and richer compared to the R3. The bass hits harder, the instruments fuller sounding and overall you are going to get a better level of PRaT from such this tiny DAP.

It does not seem that long ago since I first saw the HiBy R3 at a show in Guangzhou over 2 years ago. The main attraction was the R6 but I had never seen such a beautifully compact form factor as the R3 before.

The original HiBy R3 launched via Kickstarter in early 2018 was immensely popular with a ton of modern features and an excellent ES9028Q2M DAC to boot for around $200.

This tiny DAP was at the forefront of a slew of equally tiny DAPs that followed not long after at budget-priced specs. It pretty much set the bar for what to expect at this price point and everyone has followed suit.

Now, in late 2019, HiBy has returned with an upgraded or “pro” version of the R3 incorporating many of the subsequent firmware changes applied to the original R3 plus plenty of new and pretty important hardware changes.

From the outside, it looks almost the same. On the inside, however, well that is a totally different story. The price? Surprisingly, not that different which is a welcome change in this rapidly inflating audio market.

Tech Inside


The new R3 Pro now sports a dual Cirrus Logic CS43131 DAC implementation. This is probably the biggest change from the original R3 ES9028Q2M build. Not only does it have an inbuilt headphone amplifier but moving to dual-channel will mean all sorts of superior noise reduction. The THD+N alone has dropped significantly from 0.003% unbalanced and balanced to 0.0007% and 0.0008% on the new R3 Pro.

Connecting that to the spec battery life and THD+N and there is a massive performance upgrade on the R3 Pro already compared to the R3. Battery life is now rated at 20 hours unbalanced and 16 hours balanced compared to 11 and 9 hours on the R3. Standby time is now set at 50 days which is incredibly good. Bear in mind the 1600mAh li-poly battery inside the R3 Pro is unchanged from the one inside the R3.

There is also no loss of decoding capability on the new R3 Pro with DSD256 and PCM 32BIT/384kHZ capability as well as the firmware developed MQA compatibility that was launched on the older R3 a few months back. The R3’s Qobuz integration is also featured on the R3 Pro

Upgraded amplification

The R3 Pro also seems to have had a boost in amping output, particularly with its balanced output power numbers. On a 32Ω load, the output increase via unbalanced is marginal from 56mW per channel to 60mW which might suit those with efficient monitors. However, balanced has shot up from 112mW per channel to 220mW which is significant, especially with those ‘on paper’ lower noise performance numbers.

The lineout performance is now up to the right standard for me for use with desktop and portable amps line inputs. You get an increase from the weaker R3 1.1V LO to 2V using the 3.5mm from the new R3 Pro. This should improve dynamic range and volume control also from your chosen amplifier.

Upgraded Wireless

The Bluetooth performance has been given an upgrade also on the R3 Pro. It is not classed as Bluetooth 5.0 capable, up from the BT4.2 rating on the original R3. I suspect a new Qualcomm chip inside though it is not yet listed by HiBy as to which exact chip upgrade.

Codecs also get a boost with the introduction of UAT from the previous R3 firmware updates. This is HiBy’s proprietary codec that should be better than LDAC with up to 192kHz sampling. I say ‘should’ because I do not have a UAT capable receiver here to test that out. Still, everything is there from the legacy R3 updates such as HiByLink, LDAC, and aptX. Still no aptX HD though.

WiFi has also got a bit of an upgrade. The original R3 was only 2.4G capable whereas the R3 Pro now supports both 2.4G and 5G. That should be an assist for those looking for faster and more stable transfer rates over shortish distances. Definitely a worthy dovetail feature for HiBy’s streaming features that rely heavily on WiFi such as TIDAL and “Import Music via WiFi”.

HiBy R3 Pro


I have been combing over the R3 and R3 Pro units here at a macro level to see if there have been any external design changes and to be frank, I could only find one difference, the 2.5mm socket. On the original, it is a rubber encasing around the socket whereas on the R3 Pro it now matches the 3.5mm TRS socket with its gold plating enclosure.

Apart from that, it is the same compact dimension at 82 x 61 x 13mm and 95g in weight. The R3 Pro also uses the same materials and finishing including a smoothly contoured aluminum alloy chassis, a beautiful tempered glass panel rear, and the striking 2.5D cornered LCD IPS touch display. Still, for me, one of the best touchscreens in this class of DAP at this price point.

HiBy R3 Pro


This is the physical star of the show. It dominates everything else and rightly so considering the big pitch is a touch-sensitive HiBy OS. This is a 3.2″ IPS TFT display sitting in nicely behind a 2.5D glass screen protector. The legibility and viewing angle is massive and for such a small screen it is really very easy to read and use via touch.

The reduction in the bezel width is the same as the original R3 and does enhance the attractiveness of the R3 Pro display. It is not totally borderless, there is some more depth of bezel at the bottom compared to the top. However, I recommend picking the black color version of the R3 Pro as it blends in better with the LCD and enhances that borderless feel.

HiBy R3 Pro


HiBy has also kept the physical control rockers for volume and playback control as well as the power/screen on/off functionality on the left and right panels.

The physical controls are slimline and discreetly embedded on each panel with just enough tactile presence to find them but they do not stick out enough to disrupt the smooth cut aluminum panel lines. There is also no change in the digital IO and memory storage location and capability.

Expansion Capability

The R3 Pro still uses the R3 USB-C connection for USB-DAC, OTG and charging capabilities as well as a single microSD slot. Anyone hoping for a magical appearance of onboard memory for the R3 Pro will be disappointed.

However, as before, there are no theoretical limits to external memory card capacity or OTG capable powered external HDD usage. You can go ahead and stick in those 1TB microSD cards or 10TB externally powered HDD drives and they should all work. testing with a 64GB generic microSD card was smooth for scanning with immediate software recognition.

Wireless will also enhance your virtual storage options via DLNA/AirPlay, bi-directional BT access to other storage devices and of course, TIDAL streaming.

HiBy R3 Pro


The R3 Pro also retains a similar analog output capability from the R3 on the top panel. The jacks include both 3.5mm single-ended and 2.5mm TRRS balanced and both have a rated output impedance of less than 1Ω. The rating levels have considerably improved, however with a higher mW rating for LO balanced and unbalanced, (see page 2 Amp section for more detail).

The R3 Pro LO has also been improved over the original LO of the R3. It is now rated at 2Vrms compared to a ‘too-weak’ 1.1Vrms LO from the 3.5mm output but it is still not a true line-out as was the case with the R3. Still, the R3 Pro LO performance is snappier with better volume and dynamic range compared to the LO of the R3.

HiBy R3 Pro



HiBy has also upgraded the wireless experience on the R3 Pro over the original R3 launch in two key areas. The first is WiFi with the addition of 5GhZ as well as 2.4GHz for dual-band compatibility. This is compared to the previous R3 which only has a 2.4GhZ receiver.

So long as your router and broadband speed are compatible, 5GHz will provide a faster data rate at a shorter distance. 2.4GHz will offer coverage for farther distances but may perform at a slower speed. With the R3 Pro, you are now covered for both options and it should improve potential compatibility for streaming on the R3 Pro.

The second is UAT in their BT decoding capability. Now the original R3 also has UAT added via firmware, (V3.1 and V3.2 Sept 2019) so this is a comparison between the original out of the box experiences. UAT is on top of the existing LDAC, aptX, AAC, SBC codecs and a proprietary HiBy codec. If you happen to have a W5 Dongle then you can experience UAT in all its glory.

UAT stands for Ultra Audio Transmission and can transmit a maximum of 1.2Mbps (LDAC is maxed at 990 kbps) to the W5 with up to 192kHz sampling frequency (normally below 96kHz). Stability and distance may well be a factor here, however, James has our W5 So I cannot test just how good that is. LDAC will be our go-to testing and comparison on Page 3 of this review.


HiBy has also retained the always improving bi-directional HiByLink service on the R3. This is only available if you have and use the Android HiBy Music app on your smartphone.

By setting up the R3 Pro as a HiByLink Server and the Smartphone as HiBy Link client you can effectively control the R3 Pro remotely (Bluetooth connection is automatically done during the setup process). This is ideal for those who have their hands constantly on their smartphones but want to control the R3 Pro from a short distance on their desk or in their pocket if on the go.

During this setup, you can browse the R3 Pro’s media library, operate playback controls, adjust volume, and scan for media. You cannot operate the R3 Pro settings or its DSP/EQ functionality.

HiBy R3 Pro

Battery Life

A big improvement on the battery life specs on paper from the same 1600mAh li-poly battery used in the R3. I am presuming the switch to the new Dual CS43131 chipset is one factor in the improved numbers.

In any event, we go from the R3’s 9 hours balanced and 11 unbalanced to a very competitive 16 hours balanced, 20 hours unbalanced and 50-day standby time. That is almost Sony DAP performance levels in terms of battery life and they usually are one of the strongest. It is also better on paper than the Shanling M0 at 12-15 hours and FiiO’s M5 at just over 11 hours.

Since I have been testing the R3 Pro I have seen a longer battery life than the R3 for sure. Actual times will depend on your usage. For regular FLAC playback and the screen off for most of the time and no DSP, I was getting around 16-17 hours unbalanced on a 16-20Ω load, (IEM). I suspect MP3 would get me a few more minutes but my reference stuff is rarely MP3.

I got a fairly sizable drop in the battery life for balanced or higher loads and a drop again when using WiFi for streaming and BT combined with MSEB. Might have been under 13 hours for balanced but I think BT drains my battery the fastest. I am not the world’s greatest battery watcher and I tend to poke and graze me collection quite heavily so YMMV.


I do not see any mention of quick charging capability in the R3 Pro manual. With the same battery size and USB-C charging functionality, it should be around the same charge cycle time as the R3. That’s around 3 hours for me from 0% on a 0.5A laptop USB-A port, possibly shorter from a higher spec wall charger equivalent.

HiBy R3 Pro

Packaging & Accessories

The R3 Pro, like the R3, is a relatively basic unboxing affair. It comes in a small white two-piece retail box and a neatly packaged dual-layer foam protector with the R3 on top and the accessories below.

I am fine with that apart from the included hardshell transparent case. It is a little basic for me and I have never thought the R3 was as robust DAP with that glass rear panel and exposed LCD screen. There is some good news, however. The optional R3 leather case fits the R3 Pro perfectly and I would advise you to buy that because it is an excellent little protective case.

HiBy R3 Pro

The R3 Pro accessory list also comes with a couple of screen protectors with one pre-applied on the rear that you simply peel off the top layer and you are good to go. Essential stuff if you ask me. The front one was not pre-applied however. I can only presume choice here as not all screensavers work that well with 2.5D curved glass and you may not wish to apply one.

Apart from those, you get a really nice nylon-jacketed gold-plated USB-A to USB-C cable for charging and data transfer and an assortment of Certificate, instructional and warranty guides in black.

    based on the merely very positive reviews about hiby r3 pro, I ordered one and received it. I agree with all of those who use it wired, that it sounds gooood. One issue I can’t accept, is the bluetooth performance. Living in the 21st century everything is about mobility. This device has serious problems with bt. abilities. Triing with different loudspeakers, iem-s, earphones, it’s unstable, stutters from time to time. It works after some time when laid down. Latest fw installed, scanned properly, so only hope remains it will be cured, if it isn’t a hardware issue. Unfortunately this side of r3 pro’s performance will not made clear for readers.

  2. Tedjo

    Hi Marcus, thanks for your review. Can R3 Pro play in bluetooth-mode with MSEB enabled? Can it play-by-folder continuously? Thank you.

    • Marcus

      Hi, yes MSEB works as far as I am aware when sending a BT signal. I have tested this before during the review. Folder by Folder I am not sure as I tend to use the tagged database rather than folders.

    Looking to jump into some upgrades to truly experience my evergrowing FLAC/Hi-Res music collection (currently I have a FiiO X1 and Bose QC35II headphones)

    Up until this point I’ve only been looking at FiiO players (since that’s all I’ve really known to this point for the price point I’m looking to stay in – $200-$250 for the player). But I stumbled across this review and it looks like everything I could possibly want (for my budget and limited setup). What is the difference going to be between the R3Pro and the R3Pro Saber that’s due out? Is it worth waiting on?

    On the headphone front, I’ve been looking at the Sennheiser 58XX Jubilee and the Sennheiser 6XX from Massdrop (again for budget reasons – probably willing to go up to $300 for headphones if needed). Would either of those pair well with the R3Pro/Saber? My primary genres of music for hi fi listening is Classic Rock (Pink Floyd, Led Zeppelin, Queen, etc), some harder rock/metal (AC/DC, Metallica, etc). Sorry for the long winded reply. Thanks for any advice/help someone might give me :)

    • Marcus

      Pro saber uses a Saber DAC and sounds more neutral and cleaner. The two Senn’s need a bit more power so I suggest looking at the HiBy R5 or a small portable amp.

      • DiamanteLoco

        Any recommendations for a decent but not super expensive amp that would go well with the R3Pro/Saber and either Sennheiser headphone?

        Thanks :)

    • Sotiris

      I’m about to buy a Hiby R3 Pro and I would like to know if it works with windows 10 and if it supports archives mp3 and wav.
      Please respond.
      Thank you.

      • Marcus

        If you mean if it load the microSD card as an MTP file share yes and also as a USB-DAC. It should support mp3 and wav.

  4. Jacky

    Just own the R3 Pro today! What a stupid machine! if your language is not English then you cannot see Tidal for login!

    • b

      There are more stupid things about this device. Like… It doesn’t work.
      Mine keeps CRASHING and STUTTERS on just playback. All these reviews.. ( got the Saber version) seem to be waay more positive than the actual device i got.
      And it’s probably the saber version, but half the notes sounds like a bag of crisps being opened. or like continuously unplugging the cable during playback. Nothing analytical, just ruined the sound. It’s so useless i’m gonna try to return or just throw it away and take the 200 as a loss.

      • Marcus

        SOrry not heard the sabre version but for the crashing and stutters, if this local playback or streaming? Generally, I find a reset or flash the firmware solves some initial issues.

  5. Ricardo

    Hi… I have a Fiio X3MKII and looking to upgrade. Looking at the Hidizs AP80 Pro and R3 Pro… any thoughts? (FYI: Usinh Bose QC35II ou Senheiser Momentum over eyer)

    • Marcus

      The R3 is not as powerful as the X3MK2 but light years ahead in terms of system stability and resolution. Also, smaller which can help :) The AP80 is good for the price, however. Depends on your budget but for a few bucks more I would pick the HiBy R5, especially if you are using headphones.

      • Ricardo Ribeiro

        Why is the R5 a verter choice for headphone users? (Sorry of this is a basic question…)

  6. Mario

    Hello! I just read your review and it is great. I am thinking of getting the R3 pro. I only have the Sennheiser 599 and usually use them with my iPhone. Will the R3 pro make any difference in my listening experience?
    Thank you!

    • Mario

      Additionally. I would use it mainly for FLAC files and my increasng my collection of 24 bit files.

    • Marcus

      Yes at a high level it will. However, for the Senn 599 I suggest a little more and getting their R5 instead. It is vastly more powerful which the 599 will enjoy. Also, you get the full Android experience.

      • Mario

        Thanks for q the quick respoke! I just read the R5 review and it definetly is the one to go! Already ordered. Thank you very much again!

  7. Terry Thorman

    Hi there

    Just bought the R3 Pro – could you recommend a decent pair of not too expensive IEMs to go with it – I have been looking at the KZ ZS10 Pro? Posted again as a typo in first post.


    • Marcus

      Sorry, no experience with KZ and I was going to recommend the Creative Aurvana Trio but that might be above your budget.

    • ZolaIII

      FiiO FH1s are great EMI’s around 70$, from cheap one’s Blon B03 or a Tin T2 (both are bit lazy but good tuned to Harman MSEB helps speeding them up). More than anything above I would recommend you Creative Aurvana Air which aren’t EMI’s but earbuds 65$ currently. But it all really depends up on your personal preferences for me Aurvana Air is still the best.

      I must say Marcus still has great hearing.

  8. Marcos

    Hi Marcus, great review as always!

    Quick question, related to sound quality, how is the r3 pro different from the Fiio BTR5?

    I ask that because all of my music is in my phone and I generally use it through LDAC in my shanling m0. So I’d probably use the r3 pro as a bluetooth receiver most of the time. The outputs generally are a TinHifi P1, a Sen hd600 or a Ruark MR1 mk2.

    Thanks a lot!

    • Marcus

      Gosh I don’t have the BTR5 but I don’t think the HD600 will be powered adequately from the R3 Pro, I would go with the R5 for that one.

      • Marcos

        Thanks for the reply! I think maybe if in balanced it could, right? My shanling m0 with 80mw @30 Ohms kind of powers it fairly well.

        What about regarding the dac, should there be much difference between the m0 and the btr5? I thought about the hiby R5, but I just think it’ll too big for my taste, I just want something light and small that allows me to take together with my big note9 and my wallet in my jeans pockets

      • Marcus

        well, balanced output is better but still, the price difference right now between the R3 and R5 would make me want the additional quality power for an HD600/650. Still, if the size is what matters then I guess its the R3.

  9. Radovan

    Hi there,

    thanks for the great review. As explained in your review, TIDAL Masters are not visible via the TIDAL integration. Would that mean the masters albums stored in my personal collection are not visible either?
    Also considering an USB DAC setup sourced from e.g. TIDAL or Audirvana on Mac, do I assume correctly the R3Pro will render MQA (including TIDAL content) accordingly, but not show any format information?

    Thanks a lot

    • Marcus

      I don’t remember seeing any format flag on TIDAL via the R3 Pro though there is an info section. When you say store do you mean offline content or your own MQA collection? There is no TIDAL offline on the R3 Pro.

      • Radovan

        Thanks for the reply. I meant my Tidal MQA albums stored in my personal favourites, not the offline content (such as this is apparently not supported). I basically looking for info if there is any option to stream Tidal MQA and then if the R3Pro supports rendering Tidal MQA in the USB DAC setup when sourced from other an other device (such as Tidal on Mac or iPhone).

  10. John Kiew

    Thanks for the great review, am comparing M9, R3 Pro and M2X. What is your thoughts?

    • Marcus

      I have not heard the M2X but if you need power and full android then R5. R3 Pro is only relevant if you prefer the sound signature and using very sensitive monitors. M9 for me is a no compared to the R5.

    • Marcus

      That Gear Patrol was written in March 2018 when the R3 was just launched and a statement that HiBy hoped it would be having TIDAL offline. Sadly, they could not get TIDAL offline due to the way TIDAL does encryption for offline playback. Pity.

      • Peter

        To bad! Have you compared this to the Fiio M6? That one does Tidal offline, so might be an option. Or the Onkyo DP-X1?

  11. Kerry Maxwell

    Thanks for the info, it appears mostly what the Pro has over my R3 is virtually useless for my purposes! An e-reader and pedometer?! Ha! The increased output section is nice, but not worth an upgrade for that alone.

  12. Alex

    Hello! Thank you for the review.

    Does R3 pro have enough power to drive a full-size 18ohm headphones (over-ear momentums) using 3.5mm port?

  13. SJ

    How does the R3 Pro compare to the Cowon D2? They both use the same DAC’s and the Hiby is $100 cheaper than the Cowon.

  14. Spritz

    Hey! Thanks much for the great review.
    I’m entirely new to this audiophile world, and I need some help :)
    I’m looking for a replacement for my laggy fiio x1 ii, and thinking about purchasing hiby r3 pro. My headphones are Whizzer Kylin a-he03, and I can’t check DAPs myself before buying. Will it be a good match, or if otherwise, what DAP would you suggest?

    • Marcus

      For the basis of good matches always look to power and sensitivity matching before tonal since most DAPs these days have excellent DSP to fine-tune. However, if no dynamic range then it is not worth it.

      I have not heard the Whizzer but at 28 ohms and 98dB SPL I can’t see an issue with the pairing and should have plenty of headroom.

      • blazer39

        that’s good to know, however would like to know in terms of sound quality/tonality…is R5 200$+ better than r3 pro?

        btw, good review as always :)

      • Marcus

        Off the top of my head a bit more body on the low-end, a bit more intimate and bigger vocal presence on the R5.

  15. George Lai

    Hi, I’m a bit confused by your comments on the BT performance so I hope you can elaborate. I’d like to also use this as a transmitter of, say, FLAC files stored on its mSD card, to BT5.0-capable TWS (True Wireless Stereo) earbuds. Are you saying the BT performance is not very good? Thanks.

    • Marcus

      Hi George

      Long-time no chat! :)

      Actually what I am saying is that performance will ultimately be a sum of 2 parts – the transmitter and receiver. I suspect the BT chipset inside the R3 Pro is ok but not as strong as a regular smartphone chipset. The stability and distance will ultimately depend on your TWS and how good the chipset is inside that. If that is ok then it should be stable enough with the R3 Pro.

      • George Lai

        Hi Marcus,

        Yes it’s been a while.

        Thanks for the clarification. Have a Merry Christmas. Thank you for a year of great reviews and here’s to an even greater 2020.

  16. Steve


    Great review!
    I have the R3 Pro, and the Campfire Cascades, .. so I have a pretty specific question for you! :) Whilst the R3P can drive the cascades no issue, … how does the sound change when you use an amp..? Was thinking of maybe getting the Monoprice THX portable.

    Have you tried connecting it with an amp? What were your thoughts?


    • Marcus

      Hi Steve

      Thanks for the positive feedback and glad you enjoyed it. The Cascade will sound punchier with more power but then a good amp will do that 9 out of 10 times.
