OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 30K+ MUSIC ENTHUSIAST
Let customers speak for us
from 4731 reviewsIf you are looking for a pair of headphones that would be your end game on a budget, then look no further, Edition XS is the way to go.
I have been using these for about 2 years and finally I can say, these cans a robust, dynamic and neutral to slightly bright.
But it also packs a punchy bass and has a good soundstage.
All you need is a pair of Edition XS and further you can keep leveling up the sound quality by upgrading cables to balanced ones, getting good DAC/AMPS and also modding the cans with new filters and grill.
Pros:
1. Sound is excellent for the price. I would say moondrop chu level sound quality. It follows the harman target with a little but turned down treble. Many people find the harman target a bit harsh at the top end. But this solves the issue.
2. I never had connectivity issues. Pairing was easy. As soon as I bring out the earbuds from the case, the buds automatically connects to my android phone.
Cons
1. App could be better. Obviously the app and other functionality won't be at the level of other mainstream tws like bose, samsung etc.
2. The fit. As someone who mostly uses wired iems. The tws does not feel as comfortable as the iems. For my ears, it's only comfortable for an hour or so. After that, it gets really uncomfortable.
I have been through some online videos/reviews before this purchase. My shortlist were, Moondrop Chu II, KZ Castor Pro, Wan'er SG. Audio Store was kind enough to provide demo of these to compare. Also Mr. Pritam shared valuable inputs on differences between my selected comparisons.
Very happy with the Tangzu Wan'er SG's output, everytime I listen to some of my old fav bolly songs it generates smile. Guess using it day by day increasing some sort of details or maybe I am getting use to. Best for listening for longer duration without fatigue. Bassheads may find it irrelevant to their taste. Over-all best Balanced tune IEM I must say which has some spark and doesn't feel boaring.
In the realm of audiophile excellence, where sound transcends mere listening and becomes an immersive journey, the Roseselsa Distant Mountain headphones emerge as a beacon of luxury and precision. Marrying vintage aesthetics with cutting-edge technology, these headphones offer a sublime auditory experience that caters to the most discerning of listeners.
Design and Build Quality
The Distant Mountain captivates with its retro-inspired design, reminiscent of the golden age of personal audio. The headband, crafted from solid stainless steel and adorned with genuine lambskin, ensures both durability and unparalleled comfort. The coaxial CNC-machined body exudes a high-gloss finish, presenting an extraordinary high-end texture that is both versatile and fashionable. 
Sound Performance
At the heart of the Distant Mountain lies an innovative 40mm composite topological diaphragm. This redesigned dome and corrugated ring deliver crisp, transparent treble and profound, surging bass. Enhanced by neodymium super magnets and an acoustic structure dedicated to small-sized headsets, the Distant Mountain presents richer sound details and a more natural treble extension, immersing the listener in melodious music. 
Comfort and Usability
The sponge ear pads are designed with both softness and breathability in mind, ensuring prolonged listening sessions remain comfortable. The headband supports fine length adjustments, with clearly visible scales to alleviate any concerns about symmetry. The inclusion of a stranded-free 5N single crystal copper IEM cable, coupled with a detachable MMCX design, offers high playability and customization for the user. 
Conclusion
The Roseselsa Distant Mountain is a testament to superb build quality and exceptional sound performance. Its unique tuning direction, reminiscent of high-fidelity in-ear monitors, combined with its luxurious design, makes it a standout choice for audiophiles seeking both style and substance. While it may require amplification to truly shine and could benefit from thicker earpads for optimal comfort, its value proposition remains compelling. For those who appreciate a blend of retro aesthetics and modern audio excellence, the Distant Mountain is an unrivaled choice. 
In the grand symphony of high-fidelity audio equipment, the Roseselsa Distant Mountain plays its notes , offering a professional and luxurious listening experience that is both nostalgic and forward-thinking.
I was not expecting much but this IEM sounds really good. If feels like a much more expensive IEM. The convenience thanks to the USB-C connection is great. I am able to use it on my phone, ipad and laptop. Gonna get some and gift some friends. This is a great gifting IEM / starter IEM !!!
I love the compatibility and the bill quality of the AUDIOCULAR d07, it works well with my samsung m53, . I also liked that u provide a case along with it , 😉
Good Sound Quality. Bass Treble Mid Too God Under 2k Price, Lookwise Good & Ear Fit & Gaming Experience To Good. & clear Sound Sense.
Earphone Case Too Good 👍 I like it.
Fast Delivery in 2 day delivery In My Address.
This is a solid technical iem with a very neutral tuning. Its a keeper iem for those who already have a collection of somewhat coluored or tasteful sounding iems under 10k .
Increased the volume as well as clarity of audio.
Thanks to the audio store for a quick delivery
This was my first experience with The Audiostore and it was welcoming. Happy with the service provided and customised suggestions as per need. Looking forward to buy next one. Thanks.
Awesome work
Fantastic easy to use dongel dac by Shanling. Build quality is also 👌. For a budget music lover this is a value for money. TAS keep providing such affordable quality product to us always...👍
Sparkling music, enhance volume and gives extra wide sound instrument but some time later connection gone if audio is not play
The CD player works as advertised. The single ended headphone jack has decent output, able to drive IEMs at a loud volume level. The coaxial output also works with a 3.5mm male to coaxial cable hooked to a pre-amp. Sound signature is unolocured in the territory of neutral to slightly bright neutral and corresponds well with recording and mastering of records. Worth the money imo.
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.
(All IEMs have been tested with the OE 2DualCPS Silver Upgrade Cable)
