Do you have a good phone? Maybe you can take a look at ONIX Alpha XI1, Fosi Audio DS2, iBasso DC04PRO, DC07PRO. In combo with a player APP like USB Audio Player PRO . You should have better sound than Hiby R4, which I have tried myself. It's not bad, but the dongles nowadays are really good or the next step is a >$700 player. Answer from tonyleungnl on reddit.com

r/DigitalAudioPlayer on Reddit: Hiby R6 III or R4 wich one should I go?
October 4, 2024 -

If money is not a problem, which one should you choose between them? R6 III or R4? I just sold my Sony ZX707 Japanese because of the battery (only 4 hours). I was thinking of getting a Fiio M15s, but I don't want Android 10 /11 and it gets hot as well. Astell and Kern SR35 is too small. The Hiby Pro 2 is too big... Dx180 I didn't like the know.

My decision is to pick up one of them R4 or R6 III, by now I have both in my cart waiting to decide 😂 !!!Thank you so much !

Update :

By now , I got the R4 for £170 / $220 in an offer ( half price comparing to R6, to test. I will leave it inside my backpack to use it during commute. I will buy a second dap , probably the R6 but I am afraid that it is almost the same thing as the R4. I can buy something more expensive ( budget is $1200). It will be used at home only . I have saving money for around 1 year to buy a new dap. Any recommendation?

December 19, 2023 -

In the market for my first DAP and like most folks looking for guidance. My budget is about $700 and could spring to $1000 for the right combo of DAP and IEM (currently have a aful P5). Listening is a mix of a healthy FLAC library server via Plex amp or Roon, and Quboz streaming. Bluetooth would be nice for my Galaxy II pro buds but not a deal breaker, battery life being more important. Open to other options than the ones listed.

HiBy R6 III 2025 Review — Headfonics
February 22, 2025 - Like other HiBy Android players SRC is bypassed globally and the output is bit-perfect for all apps. The Class A/AB mode still exists and I will talk more about the overall performance in the sound session. Similar to the R6 III, the new version decodes up to DSD512 and PCM 32BIT/768kHz, and also supports MQA 16x unfolding if this is still relevant to you.

Hiby R4: Making DAP's Great Again! – Nealz’s Take
August 24, 2024 - The only advantages Hiby R6 can offer over the R4 is a bigger and brighter display, more RAM and storage (4/64) and option to switch to Class A/B amplification mode. Even with the more storage and RAM Hiby R5 Gen III feels slower and more laggy ...

I'm just a casual listener with my phone and dongle DAC, but I think it's time for an upgrade. Should I jump to the R6 III for absolute sound quality and build, or save some money by choosing the R4 or R3? This will be my first DAP, and I don't know how much the sound will differ between each DAP. Is it worth it to spend more on the expensive R6 III, or settle with a cheaper DAP?

Edit: Ive just bought the R4 for $220 dollars since its a nice deal. Hope I will enjoy it till it last.

R6evolution: HiBy R6 Pro Max and R6 III (2025)_the headphone list
April 1, 2025 - There’s nothing radically different to them, but at the same time, incremental upgrades like a much larger battery in the R6 Pro Max and flagship CS DACs in the new R6 III address some of ther shortcomings of their predecessors and bring both DAPs not only closer to each other in performance, but closer to the multi-kilobuck tier too.

March 29, 2024 - I would consider the R5 II as I have no interest in streaming so Android version means nothing to me and not a big reason to choose the R4 instead. Then again, Hiby has not yet ported their Linux OS to at least the Ingenix X2000 like Shanling did with the MTouch DAP's.

r/HeadphoneAdvice on Reddit: Hiby R5 Gen 2 vs Hiby R6 Gen 3
January 29, 2023 -

I know about a month a go I announced my endgame on r/headphones but well, I couldn't help it, we all have to fall for the SHINY once in a while.

Back to the point, I'm considering a mid-tier DAP to use with my IEMs and headphone. Still, I'm pretty conflicted between the Hiby R5 gen 2 and the R6 gen 3, Hiby is currently having a sale which makes the price of the R5 gen 2 very appealing but my question is:

Is the difference in sound between the R5 and the R6 worth the extra price?

Both use class A amp but the R6 uses a more powerful CPU with Android 12 while the R5 has a ludicrous battery life, is it worth getting a technically speaking better DAP at the sacrifice of the 35-hour battery life of the R5?

Any other recommendations would be greatly appreciated, preferably something that is less than $1000, feel free to share your experiences with both devices.
