HiBy R6 III 2025 Portable Digital Audio Player














































I bought the original R6 mark 3 soon after it came out, and a few months later I bought another on sale because I liked the first so much I wanted a spare in case the first got lost, damaged, or stolen. So obviously I’m a big fan. Why? To me it’s the perfect mid-size mid-price mid-fi DAP. The form factor is ideal, it fits my hand perfectly, it’s not too heavy while still providing long battery life, the screen could be brighter but is extremely legible and sharp, Hiby players are all loaded with bonus features like MSEB and PEQ, and the sound is rich, accurate, and dynamic. The latest model improves on all this with new DAC chips, a more open sound, more memory, slightly better battery life but the same solid construction and excellent Android experience, all for less money. What’s not to like?
Good choice, maxi sound, more feeling, beautiful unit !
This is an absolutely excellent DAP. It is very user friendly and has awesome features in terms of music apps you can download tot he R6 III 2025! I love it. It plays HI- Res music beautifully!
Documentation is all photos and only covers startup and charging. Nothing about the screens to use it. Nothing about linking to stream, nothing about loading music on it. Really poor.
Otherwise, it is an outstanding dap. Audio quality is fantastic. Without a totl for direct and instant comparison, you would never find it deficient.
If they would just get someone highly fluent in English to write a user manual.
Listening with Leo's switch tuning 'ON', if I were to describe it in one sentence - very coherent, natural, musical tuning with top tier technicalities in the best possible way. If you are looking for a top tier all-rounder, look no further than the Pentara. With the amount of drivers and crossovers, it is impressive to achieve such technical details and tuning at a truly flagship level. Buy with confidence if this is what you look for
Pronounced and very high quality, tight, punchy, textured, controlled bass. Mids with enough warmth, emotion, note weight. Never thin or analyctical. Treble that provides clarity, detail, and air without sharpness and fatigue for me. Very deep and wide soundstage that expands like a sphere. Excellent resolution and imaging. No congestion. I do not have issues with anything in the frequency range that I can fault personally like I do with other IEMs. Everything just sounds right. Nothing sounds artificial or weird. Not recommended for bassheads seeking for more bass but rather for those that want neutral-warm leaning sound with pronounced and elevated bass.
UM's tuning switch '1' leans slightly less bass quantity, more clarity, and opens up the soundstage a little bit
Two different tunings that are noticeably different but useful from each other rather than being inferior. Easy to use the switches that compliment each other with tacticle sound
90% of the time I will prefer the switch on with Leo's tuning because it invokes a lot more emotion and dynamics with the elevated bass and warmth in the mids. Just my preference
Fairly easy to drive but scales with power or better DAC/AMP
Only major gripe I have is that the stock cable sucks tbh. Not ergonomic, heavy, stiff, minor microphonics, emits a minor sinewave hiss with my DAP as a USB DAC which I do not have with other cables. Recommend using a better cable up to user's choice
I notice that the treble does get a little spicy with poorly mastered songs with elevated treble though that is fairly rare
Lack of accessories and unboxing experience is not a big deal if you are ultimately chasing the sound anyway
As a self-proclaimed Astell fan and current owner of an SP3K, I hesitated quite a bit before upgrading to the SP4K, wondering if it was a halfway point (like an SP3.5K). I also wasn't particularly interested in an open-source Android system. Fortunately, I decided to take the plunge. The SP4K has turned out to be a complete surprise, to the point that it's the best DAP I've ever heard in terms of sound quality. A huge soundstage, bass with a texture I've never experienced before, and an astonishing level of detail. A total success.
These punch way above their price point. Very good bass for ba drivers that doesn’t make me miss dynamic drivers. Great technical performance, extended treble but not harsh. Love this set!
