HiBy R2 Ultra-Portable HiFi Player Review






HiBy R2 Ultra-Portable HiFi Player Review



HiBy was established in 2011 and is specialized in research, development and sales of Hi-Fi grade portable audio products such like DAP’s, USB & BT DAC’s and earphones. HiBy has also an experienced software team that has developed HiBy OS which is also one of the most widely used professional portable audio Operating Systems (OS) on the market.

The HiBy R2 is the new entry level Ultra Portable Digital Audio Player of the company and comes with a single ES9218 DAC Chip that supports PCM up to 32bit / 384kHz and Native DSD128.


I would like to thank HiBy for providing me the R2 as review sample. I am not affiliated with HiBy beyond this review and these words reflect my true and unaltered, opinions about the product.


Purchase Links:

The actual price for the HiBy R2 is $99.00 USD, but HiBy offers an early bird promotion with a price of $89.00 USD that is valid until October 20, 2020.



Package and Accessories:

The HiBy R2 came in a relative small box that is in black color and has the product illustration and some brandings on the top.

Design, Buttons and Build Quality:

The HiBy R2 is a product with an impressive build quality for the price, same like all previous products of the company. The R2 comes with an all-new zinc alloy chassis in gunmetal color that looks very robust.

The HiBy R2 is an ultra-portable Digital Audio Player with fairly small dimensions. The outer size is 61x61mm and is pretty slim with a thickness of 12mm. The R2 is also a lightweight player that weights only 85grams.

On the front of the HiBy R2 is the 2.45” touch screen with a pixel density of 480*360. The touch screen is very responsive even with the pre-installed screen protector. The color reproduction is also ok for such a small device with a price below the 100 USD mark.

The glass of the screen has shows a nice 2.5D curved design that fits nice with the metal frame of the device.

On the top of the HiBy R2 is one of the two microphones and the power button that has a LED light indicator. This LED lights up in different color that gives information’s about the device working status (BT Codec, File Format, etc.)

At the left side of the R2 are the buttons for volume up & down.

On the left side of the R2 is the second microphone, the next, play/pause and the previous button.

At the bottom of the device is one (1) Micro SD card slot that supports cards up to 2TB. Here is also the multifunctional USB Type-C port and the 3.5mm headphone jack.

The rear side of the device has a glass surface that shows the product branding, the Hi-Res/Hi-Res Wireless logos and some industrial certifications, etc.

All buttons of the HiBy R2 are quite easy to use/navigate even if the player is in your pocket.

Hardware and Software Features:

The HiBy R2 Digital Audio Player features some nice hardware specs for a device with such a reasonable price.


A. Processor & Storage:

The HiBy R2 comes with the same Ingenic X1000E CPU that is integrated to their bigger brothers, the HiBy R3 Series. The processor speed of X1000E is 1.0 GHz and offers an energy efficient MIPS32 XBurst RISC core with double precision hardware float point unit for low power consumption.

The performance of the X1000E is pretty good and offers a fluid operation of the R2.

The HiBy R2 doesn’t comes with an internal memory, which means that you will need storage card that you can put in to the MicroSD card slot in order to listen to your favorite songs. Micro SD card slot supports storage cards up to 2TB.


B. DAC / AMP Section:

The HiBy R2 comes with the ES9128 SABER HiFi SoC (System on a Chip). The ES9218 SABRE HiFi SoC is a 32-bit, 2-channel, parallel quad audio digital to analog converter integrated with headphone amplifiers, analog volume control. It supports PCM up to 32bit / 384kHz and up to DSD128 decoding.

The ES9128 SoC features an integrated amplifier with an output power of 70mW for each channel @ 32ohm.


Supported File Formats:

The HiBy R3 Pro Saber is capable to play a wide range of audio formats such like MP3, FLAC, APE AIFF, WMA, WAV, ALAC and supports also Native hardware DSD (Dsf, Dff, ISO) Decoding up to DSD128.

The HiBy R2 supports also the new MQA Audio standard (4x unfold supported). MQA – short for “Master Quality Authenticated” is a new way to experience high-resolution audio.

MQA encoding folds studio-quality audio into files that are small enough to stream (or store in large quantities on a portable device). But the encoding process doesn’t just make hi-res music files smaller. It makes them sound much better, too.

You can buy a limited selection of MQA downloads now. They play through any equipment that can decode lossless file formats (WAV, FLAC, and ALAC).


C. Connectivity:

1. Wired:

The HiBy R2 Digital Audio Player comes with an 3.5mm single ended (TRS) headphone output that delivers a output power of 70mW @32 ohm for each channel. The HiBy R2 can also be used as an asynchronous USB DAC with both Mac’s and Windows PC’s. To use the R3 Pro Saber as USB DAC, you need to be set “USB mode” to “USB Audio” in the system settings and connect to your PC/MAC with the supplied USB Type-C to USB A data cable.

For more information and driver download, you can use the link below;



2. Wireless:

a) Bluetooth & Bi-Directional Connectivity:

The HiBy R2 comes with the latest Bluetooth 5.0 standard and supports also “Bi-Direction Lossless Bluetooth Connectivity” which can be used to transmit or to receive/stream your music from any compatible device.

The Bluetooth connectivity performance of the R2 was pretty stable connected to my Samsung Galaxy S9 Plus during my tests, without to show drops and noise issue from a distance up to 9-10 meters.

  • Supported Bluetooth Codec’s are UAT, LDAC, aptX, SBC, and AAC.

This is a nice feature if you want to stream songs from online music services such like Spotify, Tidal, Apple Music, etc. over Phone, Tablet or PC.


b) 5GHz High Speed WiFi:

Another nice feature of the HiBy R2 is the support of 5GHz WiFi streaming functionality for a high speed WiFi audio and data transmission / reception.


c) HiBy Link:

A very usable feature of the HiBy R2 is HiBy Link, which allows you to play Hi-Res music stored on the R2 via remote control on your Smartphone. In order to do this, you will need to install the HiBy app that you can easy download to your phone/tablet.

  • I have tested only the Android version that you can download from the Google Play Store.


d) UAT (Ultra Audio Transmission) Support:

The UAT (Ultra Audio Transmission) is an all-new Bluetooth audio codec developed in-house at HiBy. Supporting an industry-highest sample rate of 192kHz at an industry-highest data bandwidth of 1.2Mbps, it can even adapt and optimize itself to different music genres.


D. Battery Life:

The HiBy R2 is an Ultra Portable Digital Audio Player that has an integrated 1000mAh battery that offers a pretty impressive performance thanks to the use of low power Chips like the Ingenic X1000E CPU and the ES9128 SABER DAC SoC.

I have tested the battery life of the HiBy R2 under the following condition and file formats.

  • IEM’s                          : HiBy Beans, Meze Audio Ra Solo, BQEYZ Spring2
  • Flac 16bit/44kHz        : approx 14 hours (Volume 35 out of 100, Screen Off)

The standby time of the HiBy R2 is according to HiBy approx 20 Day that I couldn’t test but what I will update after some intensive use.



 E. Extra Features:

  • Dual microphones for high quality stereo audio recordings.
  • MSEB “MageSound 8-ball” a sophisticated audio Remastering system developed in-house by HiBy.
  • HiByLink (Operate your pocket R2 from your huge Smartphone screen).
  • Built-in E-Book Function
  • Internet Radio


F. The Software:

The HiBy R2 comes with an in house developed Operating System that the so-called HiBy OS, which is a Linux based software specially created for portable audio devices.

I do graphical user interface (GUI) is simple to use and very fluid in its overall response. It is also pretty easy to navigate thanks to the well implanted swipe gestures.

The Player shortcut links you to the player interface that is minimalistic but clean. Here are a number of swipe gestures you can do to open some new windows.

The HiBy R2 offers a 10 band Equalizer that can be manually fine-tuned, while you have also the option to select one of the presets like Rock, Pop, Dance Metal, etc. that is a quite common feature for many players on the market.

However, which makes the R2 special and superior compared to most players in the same price range is the MSEB (Mage Sound 8-Ball) that is developed by the HiBy software team.

MSEB is a combination of multiple algorithms based on parametric equalizer (PEQ) and sound field adjustment (in short a DSP tool) that works pretty good If you like to play/transform the sound of your device. I normally do not use any type of EQ settings on any of my devices but the MESB is one of the best solutions in this category.

The Sound:

The HiBy R2 is a Digital Audio Player with a pretty neutral and bright tonality, which offers a fairly good overall resolution and output performance for a Ultra Portable device with a price tag bellow the 100 USD range.

PS: The review is written after a burn-in for about 50 hours and is based on my sound experiences with the HiBy Beans, BQEYZ Spring2 and Meze Audio Rai Solo In-Ear Monitors.

Bass / Midrange / Treble / Soundstage:

The subbass region of the R2 shows a sufficient level of depth and extension. It’s sounds quite controlled and is showing a moderate amount of intensity and rumble.

The midbass area on the other hand has a touch more boost compared to the subbass region, but still sound pretty neutral especially when paired with the BQEYZ Spirng2.

The overall bass extension and speed is quite good for an ultra portable DAP in this price category and doesn’t have shown any negative situations like a midbass hump or mixings thanks to the fairly neutral tuning.

The midrange of the HiBy R2 sounds fairly clean and offers also a surprisingly good level of detail retrieval when paired with Meze Rai Solo or BQEYZ Spring2. The general presentation in the midrange is transparent with a slightly boost in the lower and upper midrange area to obtain better level of dynamic in this area.

Both male and female vocals do sound quite natural & realistic, while male vocals have shown an average depth and female vocals are fairly clear and transparent in presentation, especially when paired with the Hybrid Spring2 In-Ear Monitor.

The upper midrange of the device sounds slightly more highlighted compared to the lower midrange region. The upper midrange character offers nice level airiness and transparency when paired with the HiBy Beans.

The treble range on the other hand has a moderate level of extension and detail retrieval, which is quite acceptable for such an entry-level device. The lower treble shows a sufficient amount of clarity, while the upper treble area offers an average level of sparkle and airiness.

The HiBy R2 offers a fairly precise placement and sufficient separation of instruments and vocals. The soundstage shows an average level of expansion with good enough depth for an entry-level device. There air between the instruments is on a moderate level.



Some Comparisons:

HiBy R2 versus FiiO M3 Pro:

The FiiO M3 Pro is a tad warmer in tonality and shows a slightly more rounded, softer/smoother overall presentation. The subbass and midbass region regions of both devices are quite similar in terms of response, while the M3K shows slightly more midbass depth when paired with the BQEYZ Sping2. Both devices are quite successful in terms of bass control and detail retrieval.

The midrange of the HiBy R2 sounds slightly more neutral and transparent compared to the M3 Pro that has a smoother and slightly more entertaining tonality. The upper midrange and treble region of the HiBy R2 sounds a bit more pronounced and detail, with better level of extension, while the difference is quite small. The M3 Pro offers a slightly smoother presentation in the upper midrange and treble region.

The soundstage of both devices performs pretty well in terms of separation and placement f instruments and vocals, especially for devices at this price level. The HiBy R2 has the upper hand in terms of soundstage wideness, while the M3 Pro has a slightly advantage when it comes to the depth.



HiBy R2 versus FiiO M5:

The HiBy R2 has a slightly warmer tonality compared to the FiiO M5 that is a bit more neutral in direct comparison.

The subbass and midbass region of the R2 shows slightly more depth and extension while both do offer a sufficient level of layering. The R2 shows bit more subbas rumble and intensity compared to the M5 when paired with the HiBy Beans IEM.

The midrange of both devices offers a decent amount of clarity and detail retrieval with all three IEM’s I have listen to it. The lower midrange of the HiBy R2 sounds slightly fuller and musical, while the FiiO M5 is a bit more transparent in this area.

The upper midrange and treble presentation of both devices is successful in terms of overall resolution end extension, while the HiBy R2 has a an slightly advantage in the upper treble region that makes it a bit more detailed while listen to instruments like pianos and cymbals.

The soundstage of both the HiBy R2and the FiO M5 is quite close in performance in terms of separation and placement of vocals and or instruments. The soundstage of the HiBy R2 shows slightly more depth, while both are successful in terms of soundstage wideness.



The HiBy R2 is the entry-level HiFi player of the company that offers a decent sound quality, great battery life and many features like Two-way LDAC, USB DAC, MESB Parametric EQ, Voice Recorder, E-Book Reader, etc. and a fluid UI. All those abilities are integrated in to an Ultra-Portable device with a very robust all zinc-alloy chassis that offers also a quite responsive touch screen.



Pros and Cons:
  • + Decent Sound Performance for an Entry Level Device
  • + Ultra-Portable design & Solid Build Quality
  • + Good Battery Life
  • + Two-way LDAC & DLNA/Air Play & USB DAC
  • + MESB Parametric EQ


  • – The Zinc Alloy Chassis is a fingerprint magnet
  • – No Internal Memory
  • – Couldn’t find any other remarkable negatives for a device at this price level


Thank you for the Read!

    could you also try connect R2 to TWS IEM? I have the R3 pro and tried to connect it with something like Fiil T1X, Aukey N5, etc., but the connection is very bad. I need to hold the R3 pro upright at my chest position and keep unmove. Any budget DAP with a good bluetooth connection with wireless IEM?


    • Gökhan AYDIN says:

      Hi, I have tested the R2 with the HiBy WH3 TWS IEM and have no connection issues in a distance of approx. 5-6 meters and it works also fine when I put it in my pocket while walking. I have only interruptions when I completely cover the device with my hands. Tbh, I have tested many DAP’s with TWS IEM’s budget or TOTL none of them was able to show the performance on my Samsung Galaxy S9 Plus. Cheers!

  2. mymail0808 says:

    Many thanks!!

    let me try again.
    but, btw,
    what can went wrong if that is really the case? you think


    • Gökhan AYDIN says:

      You are welcome. They’re so many possibilities, maybe the signal strength of your TWS IEMs or the codec you are using.

  3. Joey says:

    Hi, is this a full MQA decoder or it is an MQA Renderer also? Thanks.

    • Gökhan AYDIN says:

      Hi, according to HiBy specs is the R2 able to 4x unfold MQA file’s. That’s the only detail available at the moment. Cheers!

  4. Kiss László says:

    thanks for the great review 😎
    how good digital transport is the R2? how is the jitter level on usb out? size wise it would be a great pair with a Chord Mojo 😉

    • Gökhan AYDIN says:

      Hi there, thank you for you kindness! I didn’t experienced any remarkable sample clock issue or so called jitter with the R2 when paired withe the FD1 or Xduoo XD05 Plus. I think that the R2 could be a good transport combo paired with the Mojo. Cheers!

  5. kyle urm says:

    Can you use the r2 as a usb mic for your pc (like on a zoom call)

    • Gökhan AYDIN says:

      Hi, I will try it today. Cheers!

      • kyle says:

        Hey, did you manage to get it working or anything?
        Would love to know if its possible to do!

        • Gökhan AYDIN says:

          Hi there, I have just tried to connect the R2 to my Windows PC and Android phone, but it seems not to pair as microphone with both devices. I have take a look to the user manual but could’t find any instructions or informations about the possibility of such a function, Sorry!

  6. johny boy says:

    hi how did you connect spotify (on android) to your hiby r2? pls help. thanks

    • Gökhan AYDIN says:

      Hi there, you need to activate your Bluetooth on both your Android phone/tablet and HiBy R2. When you pair your R2 with the HiBy R2 it will show that the BT DAC is activated, now you can transmit your Spotify song’s from your Phone/Tablet to your R2. Cheers!

  7. Jel says:

    Can you use it as an LDAC dongle for a laptop? Meaning that it is connected to the laptop in USB DAC mode but transmits the music being played on the laptop via LDAC to BT headphones. If so, what frequencies are possible?

    • Gökhan AYDIN says:

      Hi there, I will try it today. Cheers!

    • Gökhan AYDIN says:

      Hi there, it is not possible to receive & transfer audio signals form portable DAP’s like the Hiby R2, Hidizs AP80 or FiiO M6 simultaneously. You will need a device like the FiiO BTA30 or iFi Audio Zen Blue to do that. Cheers!

  8. James Graham says:

    I got my R2 but can’t figure out the internet radio.
    Is it a folder issue?
    Radio.txt file?
    If you know thanks.

    • Gökhan AYDIN says:

      Hi there, Sorry but I couldn’t find any detaild about the internet radio function.
      I will contat HiBy to get more information. Cheers!

    • Bob Kolin says:

      I’ve been trying to figure it out also to use on my R3 Pro. Here’s what I just found on Hiby’s website. Seems like a lot of work. Let me know if it works for you.

      How to add Custom Radio on the R3 or the R3 Pro?

      1. Create a new text format “radio.txt” in the Micro SD card root directory with the encoding format UTF8;

      2. Open the text and fill in the station name and URL. The name and URL are separated by the English character “,”. One radio station per line;

    real mic records so well? and another thing compared to a shanling Q1 and Hiby R2, which is superior thanks !!!

    • Gökhan AYDIN says:

      Hi there, yes the mic records pretty good if you select flac format at 48kHz. Sorry, but I didn’t have had the chance to compare it with the Shanling Q1 but the R2 is a no-brainer for that price. Cheers!

  10. Shakmal says:

    Just for an update, I have no problem to connect this player with all of my TWS including Mu6 Space 2, 1More ANC and Fiil TX Pro

  11. midnight says:

    hello, choosing a first dap here. hiby r2 or fiio m3 pro? (sound, battery, ui and resolving capability wise. not including wifi/bt or other features)

    • Gökhan AYDIN says:

      Hello, both devices are pretty similar in terms of sound performans and battery life (about 15 hours for M3 Pro and 14 Hours with the R2). The UI of both device is fluid while the R2 offers a better EQ customisation. So, if BT and WiFi is not important, you won’t go wrong by choosing one of those devices. Cheers!

  12. midnight says:


  13. Leonardo says:

    Hi! How do yo compare this player to Fiio m6? This has MQA, bluetooth 5, wifi 5 but Fiio can manage apps offline. What about sound?

    • Gökhan AYDIN says:

      Hi! The sound of both devices is pretty close, not night and day difference in terms of overall sound quality. The main difference is the tonality. The M6 sounds slightly warmer than R2. So, if you can’t live without offline apps and prefer a warmer sounding source the M6 could be the right choice, however the R2 offers a great value. Cheers!

  14. Adriano Bernardino Rocha says:

    I’ve just bought the R2 and for now I’m a little bit disappointed with it. As soon as I received it, I installed the new firmware and have been listening to some tunes since then. I have nothing to say about the sound quality of the player. Everything in it sounds good. However, there is a serious flaw when the R2 plays anything from the microSD card. When a tune finishes, the other one begins with a slight, almost imperceptible break (in fact, every tune behaves like that), irrespective of the file format. And it is very annoying. I’ve already tested the gapless, crossfade, and low gain functions, as requested by a Hiby guy that is assisting me, in the attempt to fix the problem, to no avail. Is it a bug that will only be fixed when a new firmware is available? The company hasn’t answered me yet.

    I’ve also noticed that some tunes (even in MQA) in TIDAL end abruptly, that is, they are not finished yet when the next song begins. I don’t think it is a connection problem, actually, I got a feeling that the problem comes from the app, which doesn’t function properly in the player. I’ve browsed on the web for similar complaints and haven’t found any.

    Have you experienced any of these problems?

    • Gökhan AYDIN says:

      Hi there, I am so sorry for your current problems, which I didn’t experienced with my R2. However, I haven’t installed the latest FW, that may the reason of your problems. I hope that HiBy will solve your problems with the next FW. Cheers!

    • Ben says:

  15. jexuiq_05 says:

    Hi. Can you use Hiby R2 as a source for a DAC/AMP tube hybrid such as Xduuo TA-10R?

    • Gökhan AYDIN says:

      Hi, the R2 has no analog line out option. I am not sure if the TA-10R supports digital input, which will be the only way to use with the R2. Cheers!

  16. For those of you trying to figure out how to use internet radio on HiBy R2/R3/R3 pro, here’s instructions and a file with hundreds of stations over on Head-Fihttps://www.head-fi.org/threads/hiby-r2-r3-r3-pro-radio-txt-file-226-verified-stations-including-somafm-181-fm-and-more.931918/

  17. Steve says:

    Hey, was thinking of getting the r2 and was wondering, how is this device as a usb dac amp? output from my laptop jack is really weak and was thinking of getting this partially to use it as an amp? is it worth it? Is it loud? Was also looking to get a dedicated portable music player…

    • Gökhan AYDIN says:

      Hi Steve, the R2 is a quite versatile all-in one device for it’s size and price, which offers sufficient power if you plan to use it with an In-Ear Monitor. But if you plan to use it with harder to drive full sized headphones, you should take a look for for the R5 or R6. Cheers!

      • Steve says:

        Thanks for your reply, I wouldn’t consider my headphones to be hard to drive (hd25, portapro, xhr2, m50x) just when I connect them to my windows laptop, the sound is terrible. It’s was significantly better when I tried them on a friend’s MacBook…

        • Gökhan AYDIN says:

          You are welcome! Yes, the list of headphones you have shared are relative easy to driver and the R2 should be able to give enough juice, lol. I am sure that the R2 can replace any MacBook in terms of sound performance. Cheers!

  18. Ben says:

    What ir the function of gain how to use it

  19. Matt says:

    Hi… Cannot connect SONY WF-1000xm4 earbud headphones to the Hiby R2. They just don’t appear in the Search Devices list. Is there a setting I need to change? Super disappointing as these are the only headphones I have available to me at the moment (everything else is packed up and in transit to another country…!).

    • Gökhan AYDIN says:

      I have the WF-1000XM4 and will try to pair it with the Hiby R2 tonight. I will share my experiences here with you. Cheers.

  20. SPICOLI says:

    I have had te R2 for two years and NEVER had a problem. A great music player….no more Ipods….
