First of all this is my first time to experience a mid tier DAP and also I am not famillar with the other features of the HIBY R6 Pro II but i will give my best to give it an honest feedbacks.

This unit that I currently have is supervised by hiby and I was chosen to be part of the Philippines tour of the HIBY R6 pro II, which gave me the opportunity to test this device thoroughly.

I didn't gain any form of incentives in this review, and all opinions are my own.

We all have different ways on how we hear sound so your millage may vary



To keep it short here is the things that are included in the package.
  • Usb C to C cord
  • Instruction manual
  • Specialized Case for the Dap
  • Screen protector- ( Firm plastic type)
  • The Player itself
By the way this is just a recommendation, I wish that they included some adapter for the USB C to C cable since not all users may already have an adapter for that, but overall the packaging is well-rounded and everything you need to get started with the device is included

Build Quality and Design​


The Hiby R6 PRO II has a solid and premium feel to it, with its aluminum body and sleek design. I like the wavy designs in the back also the carbon design it gives it an edgy and modern look. The buttons and ports are well-placed and easy to access. It has some color indications which i will explain later, and overall i like the design and the build of this player.

Features and Light indicator​


This has native DsD support of 1024 and PCM upto 1536khz, if your a fan of MQA format the HIBY PRO R6 II can decode it upto 16x which is really helpful. This next feature is what I am suprised an amp in a DAP, and its my first time to experience an amp the type of amps used was Class A and Class AB. I personally love the Class A more compare to AB as it produces better sound quality, but both were impressive. This has some rgb functions and the purpose of it is to show you the music format you're currently playing. Since I already mentioned the rgb lightings, so here is the meaning of each color. This has bluetooth capabilities but unfortunately i can't test it due to not having any bluetooth devices. This also have an expansion sd card slot upto 2TB
  • Yellow Green- PCM ( Consists of: MP3,AAC,WAV, 24Bit/48khz)
  • Aquamarine- Hi-Res( 32bit,96khz,192khz,384khz)
  • White-DSD
  • Green-MQA
  • Blue-Standby mode
  • Red- charging mode

Ports and hardware buttons​


This has 4 audio ports and a type-c port for charging and data transfer. In terms of the hardware buttons here is the list of the buttons.
  • Power button
  • Volume up and down buttons
  • Playback control buttons (play/pause, skip forward, skip back).
Now lets talk about the ports that i mentioned, so here is the following ports you can expect in the HIBY R6 PRO II
  • 4.4mm balanced line out
  • 4.4mm balance output
  • 3.5mm line out
  • 3.5mm power output
  • Type C with 10gpbs transfer rate and charging

UI interface​


Its very snappy and clean and everything you need is already shown in the homescreen, If your famillar with slide gestures then it will be just a piece of cake. but if your use to the tradditional touch navigation buttons. adjustments will be needed to adapt to the gesture style navigation. In general the UI is very easy to understand and very responsive to gestures.

Operating System​


The HIBY R6 PRO II runs on android 12 and there is no restrictions you can modify and install the apps you like. The only app you can't remove or disable is the hiby app itself including hiby cast server, file manager,and settings but the rest you can do what you want. In general the HIBY R6 PRO II has an operating system which has no restrictions and its free to modify software.

Charging Time​

Even though is an audio dedicated device, you also need to know that this is very slow in terms of charging but its acceptable if your not in a hurry or just in your home. but if your traveling or going to commute then it may holdback since again this is very slow.

Battery Optimization​

In terms of battery, this has a 5000 mh/ah battery capacity even though it has that kind of capacity. it drains quickly and by the way I am using high gain, but even though i still wish that it was optimized properly.

Screen Display​

Even at full brightness, it still feels dim when you're close to the sun or other bright areas. but if your just in your house or indoors the brightness is acceptable. In general speaking the display will not handle the outside shine of the sun even at max settings.

Sound Signature

After doing some long assessments The HIBY R6 PRO II has that base of being balanced-neutral or warm-neutral. The sound base is really good for pairs that lacks that bass and the neutral will help to amplify the set more, so it may sound confusing but don't worry i will explain it shortly. In general explanation this is more on passive and offensive way of approach since this has a balanced-neutral signature and warm neutral.


This has two different amp style and the first one is the Class A then the second one is Class AB, if your confuse what is the meaning of both amps well i also don't know. but based on my reearch Class A is like uncompressed while the AB is compressed. For the sound I like the A more compare to AB since A has more tonality while AB is more on engaging sound.


It has that punch and tightness and becuase of that it gives more flavor to the engaging factor of this spectrum. For example the track of Get into the Abyssmare by Abyssmare the bass is super satisfying and it gives that fullness and makes it even better. Sub-bass is really good its very energetic also it hast that flavor of being lively, For example the Track of Winner by Abyssmare the rumble is so energetic and aggressive. Mid-bass is very great it gives that texture which also has great body. It also adds warmness to the sound which is prominent in the vocals, for example villian vibes by mori calliope and amalee. In general The bass is very engaging and very lively also that tightness makes it even better.


The mids are very great it has that flavor of sugar and spice, instruments are well presented with great emphasis on the vocals. The presentation is very clear and bright. Female vocals has that emotion and feel which is prominent in the track while the Male vocals its more on pleasing factor. In general the mids made me move becuase it super sweet and very clear and transparent.


I like how the emphasis on the brightness is more on natural and not forced. since in my previous reviews some of it the brightness was forced or too much emphasis on it but this one is very refreshing. The extension is great it does not give any forms of peak and sibbilance which is I like since my ears are very sensitive in too much high frequencies. In general the treble has that outstanding performance and can give more colors to the sound.


So lets start with sound stage the performance is average since it lacks the space for other instruments to shine and it has a feel of cramped room. instrument seperation is average it lacks that precision and accuracy. imaging is decent voices and other instruments can be heard but not that prominent.


I really enjoy the HIBY R6 PRO II alot .but I guess we will part ways since this is only a tour unit and not my personal unit so until we meet again my friend.

Hiby R6 Pro II: Unboxing and First Impressions
Pros: - warm, neutral sound
- rich bass replay
- tube-like sound with less distortion
- very good details
Cons: - HibyOS (as with all Android OS) has some kinks with Apple Music


I just got the latest medium-end DAP from Hiby (available for pre-order today on their website), the R6 Pro II (hereinafter R6Pro2), as part of Hiby’s review tour. Before anything else, I’d like to thank them for the opportunity to review some awesome audio gear, particularly the R6Pro2 (spoiler alert!). That being said, all content, opinions, conjectures, and errors expressed herein are entirely my own. I try not to be biased as far as humanly possible.

Out of the Box








The unboxing experience is straightforward and simple, yet stylish, setting the tone for my initial impressions. Upon opening, you are immediately greeted by the device itself, the tour unit coming in wearing sexy black (there’s a more popular purple colorway too). Its large screen is the first thing I noticed; much larger than my FiiO M11 Plus. It’s also considerably thinner than the M11 Plus (please see included photos for size comparison). I’m digging the overall design language, particularly the “waveform” design at the back, which probably helps dissipate heat. The included accessories, spartan but complete, are also well appreciated, particularly the faux leather case, the type A adapter for the type C cable, and the extra screen and back protectors. No need to look for essential aftermarket accessories. Very thoughtful.






At First Blush

Of course, I couldn’t help but boot it up immediately after unboxing. Initial boot time took just about 3 to 5 seconds. The introduction screen and dialogue boxes are straightforward and easy to follow since I’m familiar with Android from the M11 Plus. However, the R6Pro2 uses Hiby’s proprietary OS, which is a first for me.



Although I couldn’t test the touted 2 terabyte capacity of the R6Pro2, I’m happy to report that it had no problems with my 1 terabyte microSD card. The DAP was able to scan around 380 gigabytes worth of music in less than a minute.



Logging into my Apple Music account was also a breeze. However, loading my entire Apple Music Library took a bit longer, around 2 minutes. In fairness, I have accumulated a relatively extensive library and created several playlists, as I’ve been using Apple Music for quite some time now. Once that was complete and Apple Music was up and running, I immediately noticed that playback abruptly cut at the tail end of songs. My theory is that I would need to tweak the playback settings. I’ll report back to you guys once I’ve confirmed this.

Sound Impressions


My initial listen was done with the settings on class A amp mode at high gain using Letshuoer Cadenza 12 playing, as per usual, the Eagles’ Hotel California (24-bit 192 kHz) at 32 to 38 dB. Here’s my initial take, all in comparison to the FiiO M11 Plus:

  • I couldn’t help but notice immediately how nicely warmer the sound replay was. As I prefer a warmish neutral sound signature, this is right up my alley.
  • Bass was a tad richer, with the bass guitar at the intro full and accomplished (note replay from beginning to end is complete and accurate).
  • During this initial listen, I hazard to say that the sound replay is akin to tube amps, perhaps with less natural distortion. I must say that they really complement the Cadenza 12’s technical capabilities. It reveals more nuances of the tracks played by the Cadenza 12, with micro details pleasantly and subtly revealed but nothing overboard or unnaturally pushed forward.
  • At this point, I veered from my usual initial listening routine as I couldn’t help but immediately throw a few DSD files at it to test how well it could handle them. With the Cadenza 12, the details are wonderfully revealed, with a touch of warmth that ticks off my first impressions like boxes.
  • I did notice some noise when music is on pause at the class A amp and high gain setting, but nothing distracting or annoying. This could depend on the IEMs used; in this instance, it’s the Cadenza 12.


So these are my initial thoughts on the R6Pro2 based on a very short time with it. I look forward to spending more time getting to know it. I’m very excited to try them with Hiby’s Crystal6 version 2, explore possible synergies with other audio gears (headphones, IEMs, and Bluetooth devices), and compare this DAP extensively with my trusty FiiO M11 Plus ESS. Thank you for taking the time to read this short take, and I hope to see you in the next one.

One question: with the Cadenza, what volume (%) where you using on High Gain settings ? Did you already had the oportunity to test a full-size headphone in it?

Hi, Sir. Volume was at around 32 to 38 depending on the track.

I plan to check compatibility with select HPs soon, Sir. One request was to try them with the 250 ohm DT 770 Pro. I also have a 600 ohm earbud that I want to pair with it as well.

Did you ever get that apple music sorted out? Where playback would end abruptly at the end of songs most of the time?
