Design and Build Quality
Strengths:
- **Premium Materials:** The HiBy R8 II boasts a solid build with high-quality materials such as aluminum alloy, giving it a premium feel and durability.
- **Elegant Design:** The design is sleek and modern, with a well-thought-out layout that includes a large, high-resolution touchscreen, physical buttons, and a volume wheel.
- **Portability:** Despite its robust build, the R8 II is relatively portable and can be easily carried in a bag or large pocket.
Weaknesses:
- **Weight:** The premium materials contribute to a heavier device, which may not be ideal for users seeking ultra-portability.
- **Size:** Its larger size compared to some other DAPs might not be suitable for users with smaller hands or those who prefer more compact devices.

Weaknesses:

- **Heat Generation:** The powerful amplification and processing can cause the device to heat up during extended use, which may be uncomfortable for some users.
User Interface and Features

Ultimately, the R8 II is a strong contender in the premium DAP market, but prospective buyers should carefully consider their specific needs and preferences before making a purchase.

Thank you for choosing HiBy, The Audio Store and we hope you continue to enjoy using the R8 II.
I have been using this sweet device for a month & let me tell you, it is eye-opening. The learning curve has been rather steep for me since this this is my first real DAC. This is like learning to drive for the first time but you only have a V12 Ferrari. This flagship has 2 types of Amplifiers, A & AB. I have left it on A because it sounds most natural. This device is heavy, almost twice as heavy as a high end mobile, so it is not something ultra-portable. The form factor of this is like a big mobile & twice as thick. What is amazing is that for the features & quality it has, should not be possible in such a form factor. It should have been the size of a big CD player of old, but it is tiny for its features. That tells me technology has come a LOOONG way for the audiophile from the days of Vinyl & tape, then CD, now DAC. I play it via computers, Bluetooth receivers & standalone through Blessing 3 IEM. The journey of the modern audiophile has begun, for me. I still have CD & Vinyl & tapes of old & new artists. The Hiby R8 II adds yet another dimension to this.
We're thrilled to hear that you are enjoying your HiBy R8 II Hi-End Android Digital Audio Player and that it has been a game-changing experience for you. We understand that the learning curve may have been steep, especially as a first-time DAC user, but we're glad you were able to navigate through it. The A amplifier indeed offers a more natural sound, and we're glad you found your preference.
Thank you for acknowledging the quality and features of our flagship device, and we're pleased that it has exceeded your expectations. Technology has certainly come a long way, and we're proud to be at the forefront of providing top-notch audio experiences. We hope you continue to enjoy your HiBy R8 II and explore the endless possibilities it offers.
Happy listening!

I'm using first time DAC most of the people refer this varient, difference between 3.5mm jac and this DAC D07 is absolutely awesome, so much details in hearing a song and music, loved it ❤️❤️❤️❤️👌👌👌🙏🙏🙏
Solid pouch
With good space
The product is worth the money
And I personally love the your faster delivery service
I got the product just in with 30 Hrs

I like Moondrop ECHO-A Dac. It is not powerful Dac but it produces quality sound .

Great for listening to all music genres, gaming on PC or consoles or pretty much any thing you'd like to do with a pair of earphones.
Superb packaging 👍🏻 delivered what was promised.

I recently got my hands on the ROSESELSA AURORA Ultra IEM, and I must say, it has exceeded my expectations! For under 2,000 INR, this IEM delivers exceptional value and performance that can easily compete with many pricier models out there.
What really stands out to me is its versatility. The AURORA shines across all genres, whether I'm diving into classical symphonies, jamming to rock anthems, or vibing with electronic beats. The sound quality is simply fantastic, making every listening session a joy.
A cherry on top is the comfort factor—these IEMs are small and lightweight, so they don’t cause any discomfort during long listening sessions. If you’ve had issues with larger IEM shells in the past, you’ll find the AURORA to be a perfect fit. Plus, the cable quality is impressive for the price, adding to the overall value of this product.
To unlock the full potential of these IEMs, I highly recommend investing in an external dongle. I personally use the Kiwi Ear Allegro Mini DAC, and it has truly elevated my audio experience. If you're on the hunt for a budget-friendly IEM that doesn’t compromise on sound quality, the ROSESELSA AURORA is a must-try!
I also want to take a moment to thank the audio store for their outstanding service. My order arrived in perfect condition, and their customer support team was incredibly friendly and helpful. Overall, this has been a wonderful experience, and I’m absolutely thrilled with my purchase!
As a v16 owner this is a worthy upgrade .
Fit :
The iem is designed aesthetically that it fits like custom made
Sound impressions :
Treble is perfectly done with being sibilant, Mids sounds very organic and clear, Bass is the best part here it's a step up from their previous flagship v16.
Staging is better and so is the resolution, A total flagship level iem which punches above the price tag
Thanks to Pritam for his exceptional customer service and deal .
Definitely recommended

Have a great features and I am very happy after buying this m71 thanks audio store 🙏🙏

Time Spent with this DAP is more than 50 days, used many IEMs from Budget range to high end.
OBSERVATION & EXPERIENCE SO FAR.
- Wide soundstage, it's creating a spacious listening experience.
- Smooth and refined sound, with good bass & trebles. I liked it.
- little high Volume doesn't hurt ears because of spaciousness which this DAP creates.
- Main unique point is Vocals & Instruments separation, it's best.
- So far, I noticed Battery back up is really good. Will check it over time and provide feedback.
- Does not get warm that too after using for hours.
- Best software & Shanling Music app, it's very fast ( I use 1TB fully loaded Micro SD card.)
Please Note - Little more care is needed while handling as it has Glass tubes. Again it's unique offering & tubes makes music more enjoyable.
CONS-
1. Charging time ( it will get solve by software updates in future, Brand has co
nfirmed it in their post)
2. Only one colour option is available from Brand.
3. Some settings currently not present, Brand may add in future updates ( DSD gain Compensation, PEQ, MSEB, Night light short cut in quick pannel)
CONCLUSION-
a. Highly recommend those who want detailed & immersive experience.
b. THREE IN ONE- One DAP but three modes, all three sounds differently. One mode Transistor (without Tubes) and two Tube modes (Triode & Ultra- linear).

Sterdy & beautiful cable. I am using it with Hidiz MP145 Planner Magnetic IEM. It add details to music over stock cable. Makes all aspect of sound quality better.

I am writing review after One month regularly uses with my two DAP - Shanling M8t, Hiby R4.
POSITIVES-
1. Best Soundstage
2. Balanced sound
3. Musical & Makes music more enjoyable to ears.
4. No fatigue despite of metal construct.
5. Weight distribution is really good.
6. Largest Magnetic planner in the Category.
7. Details & instruments separation at best.
CONS-
1. Small ears may face challenge. Plz contact team ATS before purchase. Normal ear size, No issues with fit & long usage.
2. Stock cable is good but doesn't suit this IEM.
I am using this with Divinus Auram cable, which goes really well with this by appearance as well as by performance.
CONCLUSION-
1. Very very happy with the purchase. It's my main IEM in daily music journey.
2. My suggestion is Music enthusiast must have atleast one 'Planner Magnetic IEM', believe me I found that the the songs which I am listening since decades are sounding differently with some more details with this IEM.

The KZ Castor is an excellent choice for budget audiophiles. It delivers superb sound quality that rivals much more expensive headphones, with clear highs, rich mids, and deep bass. The build quality is solid, offering both durability and comfort for long listening sessions. At its price, it’s a fantastic value, outperforming many premium options. Highly recommended!

i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.
