If my current HiBy R6 III (Gen 3, ESS) is compared to driving a BMW, the R6Pro MAX is a Rolls Royce.
It is easy, smooth, and suave. It doesn’t make a big deal of representing a soundstage that’s exactly studio-like. Natural, not heavy on any particular frequency (do not expect heart thumping bass) and extremely coherent. It’s like you’re sitting in front of the artists themselves, in a studio, with a performance made just for you alone. Each frequency - the lows, mids, highs and everything else in between - are effortlessly detailed and precise.
All IEMs I have tried with it, i.e. the 64 Audio Volür, Symphonium Meteor, Penon Quattro and Kiwi Ears Quintet are driven best at Low or Middle Gain, with me personally finding that High Gain makes it all muddy. I am yet to try it with my HiFiMan Ananda Planar headphones, and will update this review as the journey with this masterpiece of a device continues. Rarely do I find myself being fondly attached to any device so quickly. It may be safe to say the R6Pro MAX does have something special. Only time will tell.
Lastly, the design is phenomenal and classy. The weight of the unit is evenly balanced and not top-heavy, making it very easy to handle in spite of its 500 gramme weight.
My only gripe, because I just HAVE to find one is that the case provided is quite impractical as the device tends to slide out from the top opening, and it interferes with the UI gestures. On the flip side, the quality of the case is top-notch making the device feel extremely premium with its carbon fiber-like finish.
Kudos to HiBy. Clearly a lot of effort and thought has been put into introducing something like this. We may be looking at a potential market game-changer.

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.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service

Sound quality ausom but not for base lover's

Top notch earphone Mike quality 🔥.gaming, music etc highly recommend ❤️🎧

I believe this is the best tws under 10000 rupees also it is an iem

Thank you audio store. The sound is amazing. It was delivered within time and product was perfect.

Very detail iem for the price not bass heavy

It is compact and yet have a good punch to the output it gives, the packaging was very impressive for the price.

Twilight from Soft Ears seems to me like a benchmark for single DD IEMs. The solid metal craftsmanship is commendable and when it comes to the sound, tonality, song signature and quality is presently benchmark for Single DD IEMs, may be rivalled by the Elder turii ti, which cost 3x of this.
