General Information



Instead of being a mere drive towards cost-effectiveness (or cost-no-object parts expenditure), the PWM R8II – dubbed DARWIN Multi-Phase Array (MPA) – unlocks a new era of sustainable portable performance in DAPs.
This PWM prodigy sidesteps the impractical dependance on parts precision necessary in analog circuits and filters to perform. Rather, R8II shifts the hard work into the digital realm for frequency and time-domain results only possible with high-speed DSP.

Its pulse-width modulation decoding of digital via individual capacitors and resistors is already a one-up on the standard delta-sigma modulation typically found in DAC chips.

HiBy's DARWIN MPA addresses the problems of conventional delta-sigma's inconsistent rise and fall edges at the frequency level, with adjustments made to facilitate more accurate, predictable switching on and off between 1s and 0s. This approach results in a reduction of errors by avoiding intersymbol interference.

Notably, non-linearities arising from rise and fall mismatches do not manifest as total harmonic distortion. R8II's PWM decoding does not produce harmonic errors that vary with digital output levels.

The brains of R8II are contained within its FPGA running a second generation of DARWIN digital filters. HiBy has cracked the formula for simultaneous time and frequency domain performance via its proprietary code.

HiBy-R8-II-Hi-End-Android-Digital-Audio-Player-HiBy-_-Make-Music-More-Musical-64316616.png

Comes in silver, blue & red colors.

I would like to extend my gratitude to HiBy for providing me with their flagship HiBy R8 II DAP for an honest review. This incredible unit was sent to me as part of a review tour with my audio enthusiast group. Rest assured, all opinions expressed here are entirely my own, and I have received no financial gain for this review. I do not pretend to be an expert on audio, but as a common, regular enthusiast who loves good quality music, my experiences and insights may offer valuable perspective. I recommend auditioning the product yourself to determine how it aligns with your preferences.

UNBOXING

Unboxing the HiBy R8 II is a delight. The outer box features a color-changing holographic print, hinting at the premium product inside. Sliding out the inner box reveals the DAP nestled within, presented almost like a butterfly opening its wings. Alongside the device, you'll find a TPU mixed Alcantara protective case, a screen protector, a charging cable, port protector films, a warranty card/QC certificate, and a user guide. The meticulous packaging leaves no doubt that you're experiencing a flagship product from HiBy.

HARDWARE

Once you pick up the DAP from the box, it exudes and projects a P-R-E-M-I-U-M product. From its slick stainless-steel chassis to the dual curve design of its sides and how the reflection of light dances around it’s mirror-like metallic finish, it radiates a visually stunning product as well as comfortable to hold and use. At the back of the unit, you will find a beautiful and elegant clad Alcantara material, a synthetic textile with a soft, suede-like microfiber pile, noted for its durability. Even the included TPU protective case is adorned with Alcantara on its sides.

There is no denying the fact that one of the thing you'll notice immediately upon holding the HiBy R8 II is it's weight. Its size is just about the same as my Samsung S23 Ultra smartphone, just slightly shorter and narrower but very thick and heavy. Imagine holding a 12,000mah powerbank in your hands, around 515 grams as stated in their website. This is one DAP I wouldn't be carrying around in my pocket for sure. As you would expect from a high power device, expect it to get warm when charging and in-use. Nothing to be of a concern though, normal for devices these days that uses a lot of juice. Using a 33w charger adapter, was able to charge the device from 50% to 100% in around 3 hours. So expect the most 6 hours to fully charge from a fully drained battery.

It uses a snappy Snapdragon 665, has generous amount of storage (8GB+256GB), Bluetooth 5.0, USB-C 3.2 Gen 1 port. Upon turning on the unit, you'll be greeted with a beautiful 5.9" IPS touchscreen with a solid and razor sharp 1080x2060 resolution. The display is bright, same with my Samsung S23 Ultra. Here is a pic compared to a Fiio M15 DAP:

20240425_010143-01.jpeg


Being their flagship product, this is their only DAP that uses their very own evolutionary Darwin-MPA custom DAC architecture. Developed by HiBy to be fully configurable and flexible. Here’s an animation of how it works:

Darwin-MPA Animation

We ordinary consumers don’t need to fully understand the inner workings of Darwin, just the end product..a spacious, detailed, dense and powerful sound for our ears to enjoy & appreciate. Truly an evolutionary design that HiBy will continue and further improve with their future products. Here is a graph taken from their Instagram page of the comparison of their R-series DAPs:

438639262_754546696812689_4944452218475711404_n.jpg


The unit’s amplification can be selected thru software. It has two options: class A and class A/B, which can be selected on the fly. As expected, class A would drain more battery and make the unit warmer. I chose to use class A/B instead as I find the sound difference very negligible. But if you want to absolutely have the best amplification, then you can leave it at class A for the readily available juice for your music. It also has a turbo mode which increases the max voltage therefore increases the max volume. Expect the battery to drain faster and the unit to heat up faster if both class A and turbo mode is on. You can play around which combination setting is best for you.

You can output thru it’s 3.5mm single-ended and 4.4mm balanced port at the bottom, both capable enough to drive most iems and headphones with a decent output of 225mW and 710mW @ 32ohms respectively. It also has a 3.5mm & 4.4mm line-out as well. All four are available and all are physically separate from each other. Of course, Bluetooth is also an option.

20240423_234350.jpg


Overall, the presentation of the unit, the materials used, the technology inside screams top of the line. Indeed a flagship product that truly is worth its price.

SOFTWARE

HiBy digital audio players run on an open-Android system, meticulously tweaked to maximize the device's hardware capabilities. The HiBy R8 II operates on Android 12, providing a user experience that is familiar and intuitive, especially for long-time Android users. While it lacks phone functionality, it offers a wide range of capabilities akin to a smartphone. With access to the Play Store, users can install various apps such as social media, messaging, and even video streaming platforms. Additionally, users can choose their preferred music streaming service, including popular options like Tidal, Qobuz, and Spotify, alongside the pre-installed HiBy Music App.

The HiBy Music App, a staple for HiBy users, has undergone significant improvements since its inception, now offering a smooth and lag-free experience. Users can access high-resolution music files stored on the device and stream from services like Tidal and Qobuz. Personal playlists can be created using a combination of streamed tracks and local files. The app also features a software remote, allowing users to control the device from another device using HiByLink Controller, or to use the device as a server for remote music access through HiByLink Server.

Moreover, the app offers a range of audio customization options, including an equalizer, parametric equalizer, and the proprietary MSEB (Mage Sound 8-ball Tuning) for fine-tuning the frequency response to match your earphones or headphones. The system-wide plug-ins, meticulously tuned by HiBy engineers, subtly alter the tonality and dynamics of the audio without affecting the overall spectrum, providing a tailored sound experience based on individual preferences.

LISTENING IMPRESSION

Let's dive into the heart of the matter: the quality of music delivered by HiBy's flagship DAP. To put it simply: WOW! After spending a week with the HiBy R8 II, I can't imagine going back to using my DAC dongle. The sound from the R8 surpasses expectations in every aspect.

The HiBy R8 II's sound signature is fairly neutral, offering a spacious soundstage reminiscent of a concert hall. It allows you to precisely locate instruments and vocals, whether they're in front, behind, above, below, or around you. The spatial sound is truly remarkable, immersing you in a three-dimensional sonic experience.

20240425_005306-01.jpeg


Every minute detail in the music is presented, whether it's the grand macro elements or the subtle micro nuances. There's no bleeding between instruments, and the timbre and texture of each sound are incredibly lifelike. Vocals are particularly striking, with each tone and timber coming through distinctly, from the initial note to its lingering decay. This authenticity in rendering vocals and instruments allows listeners to fully appreciate the subtle nuances of the music, as if they were seated in the front row of a concert hall.

20240423_233636-01.jpeg


Every headphone I connected, from the budget-friendly Tanchjim Zero IEM to the high-end Focal MG Clear headphones, sounded noticeably better with the HiBy R8 II. I even used it as a DAC for my home audio setup, and the richness and musicality it brought to my B&W speakers were exceptional. When connected to the head unit of my car, the sound was nothing short of exhilarating. The vocal and instrumental textures were a sheer delight to my ears. The HiBy R8 II's timbre stands out as one of its greatest strengths, unmatched by any other DAP.

20240421_183457-01.jpeg


Listening to music on the HiBy R8 II is a testament to cutting-edge technology. Whether you're using IEMs, headphones, or other audio equipment, the Darwin-MPA ensures a premium listening experience. If audio quality is your top priority, then the HiBy R8 II is a flagship product that should be at the top of your list.

Hiby R8 II A step in the right direction
Pros: - Excellent design
- Great battery life
- Wide soundstage
- Natural neutral tone with excellent
technicalities
- Great screen in size and display quality
- Modern Android version
Cons: - Protective case with alcantara finish,
despite being of high quality
- The high size and weight make
transportation and usability difficult
-Packaging and unboxing

The box of the new Hiby R8 II is functional and elegant, the DAP is perfectly protected, it is very easy to access its interior and easily remove the player, the cardboard box is well made, magnetic and well organized, I find that it is more than enough for a satisfactory experience without going into too many luxuries that make the product more expensive, the box includes:

- DAP

- Custom made TPU and alcantara case

- Charging and data cable

- Screen and top and bottom bezel protectors

- Manuals

20240505_173652.jpg


-Technical specifications:

There is nothing better than a link to the Hiby website where you can easily and in detail see all its features. From my point of view we are looking at a high-end product according to its price and specifications.

https://store.hiby.com/products/hiby-r8-ii?variant=44121041797336

-Setup, handling and system

Firts, let's talk about the screen, we are looking at a screen with very good definition, more than enough brightness and perfect size in my opinion, I have no complaints at all about the R8's screen and I only wish that other manufacturers would pay the same attention that hiby when it comes to selecting a quality panel, the better visuals and usability that come with having 6 inches in size are notable, a success.

20240505_173917.jpg


The build finish is of a high quality, it feels robust and well put together, I find the Alcantara finish pleasing as most of us will use the device with the case provided, I don't find it a problem at all, the anodizing looks very well finished.

The buttons feel solid and have a pleasant touch and recoil, you can perfectly notice the response to pressing them, the only problem you may have is due to the case provided, it is difficult to determine the real location and which of the buttons you are pressing next. If you look at where you are playing, speaking of the case, it seems to me to be of very good quality, perhaps I would have preferred that the case did without the alcantara finish, but it is a personal preference.

20240505_173854.jpg


This is a heavy device, we are getting a DAP with a large screen, high amplification power and huge battery, which implies a high size and weight, personally I still find it manageable and within acceptable limits, it can be handled with a hand that still requires some effort to do so.

The first turn on and setup of the Hiby R8 II is extremely fast, just select the language and time zone, in a few seconds you will be on the home screen ready to play your favorite music, adding the Google account is the same Quick and easy, just open the PlayStore and log in with your Google account.

In the software section we have Android 12 which responds very fluidly and quickly in general, the 8GB of RAM and the use of faster ROM memory in the system are noticeable, I have had practically no bugs and anything that I may have had It is too irrelevant to mention it since I don't even remember it, so it does not spoil the user experience at any time.

In all my DAPs I like to install Nova Launcher and Power AMP, the first is an application launcher that allows me to customize the home screen to my liking, it allows me to add certain shortcuts such as the screen lock to avoid excessive use of the button, as well as direct access to the audio configuration menu, avoiding going through the notification bar to access said settings.

Screenshot_20240505-172604.png


I like Power AMP again for its impressive customization and great appearance.

Both applications work perfectly and without hiccups.

Screenshot_20240505-174559.png


In the software section there are some things that from my point of view should be added, the first is being able to unlock the screen with a double tap and thus avoid making such continuous use of the button, the second are widgets or shortcuts to very useful functions and widely used such as Pluguins, PEQ or MSEB to name a few, this facilitates access to options that are used very frequently and avoids having to navigate through several menus.

Then there is the battery life, I will only mention that it is excellent and even though I have not calculated the hours of playback that I have achieved, it is a device with a long battery life, you can make intensive use of the screen, the WiFi and still get many hours of music playback.

-Sound

I mainly listen to Pop, Rock and EDM to give a quick description, although random tracks from many other genres are included.

To make a first general description I will say that its sound signature is extremely balanced, perfectly neutral with extended bass and treble, this giving a general U-shaped sound signature, wide soundstage and excellent tonality, the speed and technicalities are of first level.

At first it seemed a touch colder and more analytical than other DAP due to its incredible transparency and speed, but that idea quickly disappeared from my head, giving way to a sound with the best balance I have ever heard in a DAP.

It has a lot of power available and although it is possible that with most iems it will not be noticeable, if there will be a noticeable difference with full size headphones or even with certain iems, I was able to test the R8 with Grand Maestro, which is undoubtedly the iem most power-hungry I've ever been, and the extra power improves some aspects of the sound, for example helping to maintain bass definition and presence, and also maintaining clarity and separation in the most demanding moments when a lot is happening at once on certain tracks.


-TREBLE

The highs on the new R8 have excellent detail and extension, they can show a lot of detail and a lot of air, which contributes to forming its large soundstage, in my opinion its slight emphasis is on the higher treble, this avoiding the troublesome mid-high area, where the dreaded listening fatigue can appear, everything is there, with excellent precision, detail and impressive speed, despite having slightly enhanced and extended treble, everything feels natural, there is nothing that is present in an overly accentuated or artificial way, it is free of any hint of listening fatigue, if you are a person looking for a very warm and relaxed sound, you may not find that here, but I am also sure that you can get used to it quickly due to its naturalness, free from any discomfort.

-Mids

I will be simple and direct, the best, most balanced and best tuned that I have ever heard in a DAP, many times manufacturers insist on advancing the mids where they give a W shape to the sound, bringing the singer closer to a few meters from the listener or even if it seems like you're on stage with him, it doesn't seem like a realistic sound presentation to me.

Luckily, Hiby adapted another approach, the mids are neither delayed nor advanced, they are in a simply perfect position, you are not too far from the stage, nor very close, you are simply in a privileged position in which everything is heard widely, spaced out and precise, you can feel everything around you and look anywhere without feeling like you are swimming between the instruments and the artist, I will use the words naturalness, precision and spaciousness.

Each element is perfectly separated and positioned in the vast soundstage, with enviable clarity and precision. Before I mentioned the word perfectly neutral, because everything has a very correct note weight, it does not have the necessary body to classify the signature as warm, but it is also not thin enough to call it cold or analytical, it is neutral in the best sense of the word, since we have sublime image positioning, incredible amount of detail, but it still sounds natural, there is nothing metallic or artificial that It will take you out of the immersion, all of this contributes in my point of view to offering the best media I have heard to date in a DAP.

-Lows

The bass is another star of the show and another of the pillars of the new R8, they have enviable speed, texture and impact, here you will not find anything slow or bloated, they always remain in place, despite their high quantity they are never overwhelming, neither eclipse the mids or highs, another tour de force of this DAP, it is incredibly deep and detailed, with excellent control and precision, its focus lies, rightly, in the subbass, not in the low mids that, although not they are clipped, they are not emphasized, someone may prefer a little more midbass and you can easily achieve that with any of the multiple adjustments that the device offers, but this approach favors the general signature that is sought with this DAP, which is clarity and separation, with a lot of headroom and air, if you are a fan of elevared bass with good taste, excellent control, depth and speed this DAP will give you great moments.

-Soundstage & Technicalities

Both are at a very high level, the soundstage is very wide, with very good positioning and individuality of the elements, there is a lot of separation and it never sounds slow or confusing, it manages to maintain the rhythm and speed even in the most complex or busy passages , there is no sense of loss of control or congestion in the presentation.

The timbre, despite its neutrality and scarce coloration, feels attractive and natural, thus respecting the sound signature of the iem in question, the instruments obtain a lot of texture and sound realistically.

There is a certain height and depth in the sound, thus providing a certain holographic sensation to the sound, although it is true that the height and depth images are not its strong point and there is room for improvement, the effect can be perceived in a decent way, due to since all the other technical aspects are at a very high level, I don't think anyone will feel disappointed in the technical section.

-Sound customization

I think Hiby is aware of how much audiophiles like to play different parameters and adjust various aspects of the sound, if you like to try and experiment with it, congratulations, this DAP is perfect for you, you can adjust very easily multiple parameters, but let's go in parts.

The first thing is the filters, there are many available and the truth is that the changes are much more noticeable than in other devices with third-party DACs in which, honestly, it is very difficult to hear any type of change between them, I notice that they mainly affect the texture and decay of notes, especially in the bass.

Screenshot_20240505-174514.png


There is something worth highlighting and that is that the modifications work at the system level and will be applied regardless of the application used, so they will even work on Tidal or any streaming application.

From my point of view the most notable are the parametric equalizer (PEQ) and the MSEB, which allows you to adjust and modify certain sound parameters extremely easily, you get slight adjustments here and there to adapt the sound to your liking.

Screenshot_20240505-172632.png


Screenshot_20240505-172616.png


But it doesn't end here, in addition, there are several Plugins, in which to apply additional modifications to the sound, the two most notable that I tried were Sound field, which allows you to play with the width of the sound scene, and DRX10K Dynamic, which makes some sound effects, in this case, divided into three bands: treble, medium and bass.

If you think that some aspect of the sound needs some slight adjustment, you will almost certainly find a way to adapt it in one way or another.

Screenshot_20240505-172556.png


In short, it is the most complete and versatile DAP that I have been able to try, a tuning that you will hardly find lacking, a natural sound loaded with power and details, as if that were not enough, sound customization options in multiple ways, someone from further??

The only real disadvantage, not too notable, compared to other competitors in the same category such as the DX320 and N7, is a certain lack of height and depth, but it more than makes up for it in many other aspects of sound and user experience, so R8 rises to the top of my list of recommendations, if someone asks me about the value of the device, I would say yes, its high price is justified and you will get an experience accordingly.

Speechless : My encounter with the flagship R8II
Pros: - Stunning look in red or black (yes I've used both. I let you know why at the end of my review) / nice use of real Alcantara fabric
- Very responsive android dap
- Huge lifetime battery
- Hybrid case (silicone and Alcantara) of excellent quality
- Better wifi than R6PROII
- Impressive sound qualities
- Excellent amplification
Cons: - Can become a little hot on A amp and turbo mode combined
- Would have prefered a leather case to keep the luxurious feeling of the whole DAP (I'll be ok to buy one if sold one day)
Before starting the review itself, I'd like to precise the dap was a free loan of 10 days from Hiby in exchange of a fair review. This is my first review for a DAP. I'm only a passionate and not a professional so I'll do my best to express my feelings in the following words.

My current daps are the Hiby R6PROII and the R6 2020. Previously I mainly used Ibasso daps but I fell in love with Hiby in 2021. I also have a lots of dongles such as Cayin RU6 and RU7, Fiio KA17 for the most up-to-date...

I had never heard a better dap than my R6PROII and was very curious of how a flagship dap should sound. So when Hiby announced the R8II Tour opened to everyone, I took my chance.

Usually,my main listenings are with my Kennerton headphones Thekk and Vali on an external hyrbrid amplifier and on my Marshall Hanwell ( if you don't know this speaker don't juge it too harshly it is far far better than the new Marshall speakers). I almost never plug these headphones directly to my DAP's, only my IEM's.


20240412_111906.jpg


20240417_113907.jpg



So when I received the Hiby R8II I was first really impressed with its look and color. The red is really nice more like the red used in car's interiors, not really easy to show on pictures (looks more light). I also like the secure feeling we have without the case thanks to the Alcantara fabric. It doesn't slip at all. Whole impression is one of luxury.


20240417_113601.jpg



Even if it is not in my habit to plug my headphones straight to my DAP's I was determined to make several experiences with it and see what it has in its belly.

High gain, turbo mode, AB amp, Darwin default and here we go...Of course,I tried several options, filters, plugins but this is my default configuration. This is really what I prefered during my 10 days. To be honest, I'm not someone who likes to play with EQ and I didn't feel the need to do so with this R8II anyway.


Yes, it was love at the first sight (first listening to be precise :sweat_smile:) . What a sound !!!


Everything is more refined, vocals have more presence, bass is meaty. I understand why Hiby calls it the portable concert hall. I am in the middle of the recording. I feel the instruments. And it drives my headphones really well. I don't feel the need to plug them on my amplifier everytime. The amplifier is like an option to offer another colour of sound more than an upgrade now.

I've tested all my headphones, several iems and the conclusion is always the same: the R8II makes all my devices sing. And it also applies to my Marshall Hanwell.


20240417_110547.jpg



It was such a revelation, I was obsessed with the fact this beauty has to leave. I wanted it to be mine. So I've ordered my « little »portable concert hall.

It was hard but I've finally chosen the black version.

Point Blur_Apr222024_172544.jpg


I have no better conclusion.

Hope you'll enjoy this R8II has much as I enjoy it

Hi @AboveNBeyond we offer many models with a volume wheel, if you believe that is more important, you may get e.g. the R6III or the RS6 or the RS8.

To me, I would rather revisit the idea of a volume wheel when we have made further improvements on the implementation of such.
