HiBy R8 II – Your Personal Concert Hall in the Palm of Your Hand
Engineered for audiophiles who demand nothing but the best, the HiBy R8 II redefines portable Hi-Res listening with cutting-edge technology and premium craftsmanship. Powered by HiBy’s exclusive Darwin-MPA Architecture, this digital audio player delivers unprecedented sonic accuracy and musicality that emulates the grandeur of a live concert hall.
At its heart is a 16-way current-mode DAC with Multiphase PWM Array (MPA) technology, enabling exceptional soundstage, clarity, and energy efficiency. With dual independent Class A/AB headphone amplification circuits driven by ADA4625-2 op-amps and 16 customized transistors, the R8 II achieves zero crossover distortion, ultra-fast transient response, and finely controlled dynamics.
Whether you’re powering sensitive IEMs or demanding full-sized headphones, Turbo Mode unleashes a 25% power boost for even more headroom and authority. Select between Class A mode for richer tone and depth, or Class AB mode for longer battery life.
Encased in a high-gloss stainless steel chassis and wrapped with a luxurious Alcantara back panel, the R8 II is a statement piece as much as it is a technical marvel. Inside, it features independent power rails for digital, DAC, preamp, and amp stages, ensuring ultra-low interference and maximum fidelity. The massive 12000mAh battery, encased in a pure copper frame, offers extended playback—up to 21 hours in SE mode—while remaining cool under pressure.
Running open Android 12 OS on a Qualcomm 665 SoC with 8GB RAM and 256GB storage, the R8 II supports systemwide bit-perfect playback, HiByCast remote control, and 16x MQA unfolding, along with native DSD, PCM, and USB Audio output.

Let customers speak for us
This is a very comfortable IEM, I can wear them for hours without experiencing discomfort or ear fatigue. The shell are relatively small, very light and fits perfectly in my small ear. The eartips are also good and doesn't cause irritation in ear canal.
It is my first iem that i have purchased and it turned out to be the best decision ! I researched a lot before buying it as i am a bass lover. Finally bought KZ Duonic with switches c type. Every note is so clean and for every type of song it adjusts the sound. Delivery was before time and even the packaging was great! Thank you The Audio Store ❤️
After trying multiple ear tips, finally I’ve settled with Divinus Velvet ear tips along with Spinfit-W1. This is perfectly sealed for me and gives that great sounding with any of the IEMs I own. Recommended. Thanks audiostore
Its perfect no doubts there but the silver plated itself is high quality but wire built and the eartips are of low quality mic is clear and perfect.🔥👍
One of best Dac in upper mid range category, it has most powerful Sgm8262 amp along with Cs43131 successor dac. The Aura seamlessly connects with my iPhone 15 and my window Laptop. Sound quality omg what a mind boggling Sound I am getting through this with MoondropNice earphone. That's exceptional. Somehow it has connections issues with My oneplus nord 4 due to oxygenOS 15. May be it will sort out after oxygen OS updates.
ThanksAudiocular team .
I loved it , surprised totally. What a sound separation.
I was a bit sceptical about ordering it from The Audio Store as I order from Headphone Zone.
But great shopping experience with The Audio Store.
This is first time experienced IEM in ever I love this❤
I’ve been spending some serious time with the Hisenior Mega5-EST paired with the FiiO KA17, and honestly, it’s a killer combo. These IEMs have that nice, punchy bass that makes movies feel immersive, but they quickly settle into a clean, neutral side that I really appreciate. The standout moment for me was listening to Tool’s 'Invincible'—the way this setup handles the complex layers and those dual EST drivers capture the 'air' in the track is just amazing. Everything stays perfectly separated, even when the song gets heavy. Huge thanks to Pritaam for the great interaction and for helping me with the selection ; it’s exactly the kind of balanced, high-performance sound I was looking for.
Good product and excellent packing, pouch was also good quality one
The vocals are excellent, it competes with any IEM priced between 1000-1700. I bought it for less than 1000, so definitely go for it for less than 1000. One more thing, if you're a bass lover, you might find it a bit balanced, meaning it's not as bassy, though vocals are more important to me, so that's why I bought it.
This is awesome. You can hear all frequencies individually with standard level. No comparison with earbuds or wireless headphone
Really liked the design and sound . Am new to IEM’s so really not sure what to expect but sound quality was really good and better then my oneplus buds 4. This review is for newbie like me
Clean sound, loud bass. Pretty balanced overall.It still is a bang for the buck.
👌✌️👍
Observed noticeable difference iin audio quality after using this dac, heard reviews complaining about static white noise but I haven't experienced any such issues yet
