Description
A-class class-A amplification
Employing flagship-grade class-A amplification in this mid-tier android DAP, the R5 utilizes Class A discrete balanced amplification circuitry, capable of continuous high power output, with plentiful energy reserves for all music genres. Converting power with ease for the most dynamic compositions, the sound is clear and full.

Discrete output stage
With 4 independent channels of push-pull amplification with 270° conduction angles constructed of discrete componentry, including 8 high powered paired bipolar transistors, the R5 provides excellent current output power and control over variable loads. Enable Class A headamp mode for class-beating audio performance! THD is down at 0.0006% at the amplified output for unparalleled realism.

Dual High-Performance DACs for astonishing music resolution
Dual ES9219C DACs natively support DSD256, PCM768kHz/32bit high-res formats, with SNR of 130dB and THD+N down below -112dB. Presenting a highly accurate output voltage ensures the most accurate signal is given to the class-A amp section for amplification; also supports integrated DAC-amp output (economy mode) for excellent low power consumption and extra-long playtime.

Dual independent crystal oscillators, FPGA clock algorithm
Utilizing dual independent audiophile-grade crystal oscillators at 45.158MHz and 49.152MHz provides high precision timing for all audio events in your music.

Cost-no-object audio componentry naturally lays the path to quality sound
Employing 163 high-precision resistors, 19 Panasonic tantalum POSCAPs, and 4 ELNA electrolytic capacitors maximally suppress power supply ripple, yielding silky black backgrounds.

Long playtime and great sound
With 4500mAh battery yielding over 35 hours of playtime* (*in economy mode), go for days without worrying about a recharge! 10 hours playtime available even in Class-A amplification mode for maximal enjoyment of class-breaking dynamic control and sound quality.

good product nice
Thanks for the review! We're glad you like it.
I'm very excited while writing review of Hiby RT gen ii DAP. This is my first DAP experience in my musical journey. I totally and always listening with Mobile + DACs. After listening with Hiby R5 genii DAP i was totally mesmerized. I can hear all instruments at lower volume also. This is totally out of the world. So I'm at dark till now inobile world experience. Pritamji helped me a lot to come out with this mobile experience. He guide me to try this Hiby R5 genii DAP experience. The rest is history. Amazing DAP. Thanks Pritamji for suggesting me this DAP. Battery is also good. After receiving since last 12 days I'm not removed my headphone from this. Balanced 4.4mm is too good rendering. That's why this Hiby R5 genii DAP is boss of DAP. The mids are so clear and totally experience is that we are sitting at live concerts. Really this is so good one. Thanks once again Pritamji for removing from out from the mobile world. Ofcourse the delivery is totally out of the world from TAS, after place the order I received within a 20 hours. Very speedy delivery by TAS.
I'm enjoying every bit of my Hiby R5 Gen 2.. the good and bad part about this DAP is once you turn on the class A mode you can't go back to non-class A mode especially for streaming Apps (Apple CD quality) cause the sound is so amazing especially the layering/separation of instruments and vocals with class A mode on but unfortunately Class A mode eats up quite a bit of battery, hopefully it will improve as it is the case with Android phones.. somehow I felt the music played thru Hiby music app (local/Tidal) had more dynamics than CD quality songs streamed on Apple music.. but the convenience of streaming app (finding songs at your finger tip) with high quality ESS DAC and Class A amp is a stellar combination to have and Hiby has sweetened it more with SRC bypass throughout and not just native music app... another beautiful part is all sorts of jacks are available... if only Hiby had given SD 600 series SOC and Android 10 this DAP would have been unbeatable but I understand they have to cut some costs in order provide this whole package at budgeted price point... still the processor and Android can be smoothly handled if you restrict your app installation to minimal, by doing this you should have good enough resources to stream and toggle between diff apps without hiccups..
I would highly recommend this DAP cause right now this is the only budgeted DAP which comes at lower price but has almost all bells and whistles of a flagship DAP..
Shoutout to Pritam, who has been a great help in order to get this shipped and delivered to me within timelines given to me by Pritam.. it is always a pleasure doing business with Pritam.. with this kind of help & support "theaudiostore" will always be my go-to place for all portable music devices, IEM, headphones & accessories..

The carry case is spacious enough for keeping one IEM and one small portable DAC with cable. Like I have kept Muse M4 dac with dihifi cable and one IEM in it. And the shell is hard so no chance of anything happening to the IEMs.
Was the cheapest option for a replacement cable I could find anywhere. And it works flawlessly too, no complaints
Amazing product
I recently purchased the Castor Pro KC earphones, and they have exceeded my expectations. The bass is deep and punchy, yet it doesn't overpower the mids and highs, ensuring excellent instrument separation. The tuning switches offer great flexibility, allowing me to customize the sound signature to my preference. Build quality is solid, and they are comfortable for long listening sessions. Overall, these IEMs deliver an impressive audio experience at their price point!

Very good cable
Works with 0.78mm 2pin iems
Using LG g8x thinq and output is higher than the smartphone's 3.5mm output.
Moondrop Link app works well, except a few buggy connectivity issues.
Good to see that one can create any Eq profile and save it in the app as long as it's done within the parameters. Very well executed.
KZ Castor Harman Target Version – Review
Design & Comfort
Lightweight, durable, and comfortable with a detachable cable. The in-line mic is useful for calls and gaming.
Sound Quality
Bass: Punchy and deep without overpowering.
Mids: Clear vocals and instruments.
Highs: Crisp but slightly bright.
Soundstage: Decent separation for immersive listening.
Pros:
✔ Enhanced bass
✔ Balanced tuning
✔ Comfortable & durable
✔ Affordable
Verdict:
A budget-friendly IEM with great sound and comfort, though the mic is just decent.
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 🙏🙏
