We specialize in creating desktop and portable DAC & amplifier solutions, designed to enhance your audio experience to the fullest.

One of the best portables in the market right now. Dont think twice if you have the budget. Just go for it. You wont regret. Yeah there are better things but for the price it is stellar dac/amp qnd punches above its competition.
The Questyle M15 is a compact yet powerful mobile HiFi DAC and amplifier. It delivers a clean and transparent sound. It avoids coloration and distortion, allowing music to shine without interference. Compared to other dongle DACs which I own like the Monolith and Dragonfly, the M15 maintains its clarity and fidelity. The M15’s standout feature is its excellent instrument separation. Each instrument occupies its own space, creating a spacious and detailed soundstage. The M15 packs a punch whether you’re using sensitive or power-hungry over-ears, the M15 adapts effortlessly. The inclusion of a balanced 4.4mm TRRS output ensures compatibility with a wide range of headphones. I am thoroughly enjoying using it. Not just a DAC. Not merely an amp. It’s a whispered promise—a symphony in your pocket. 🌟🎵

We also appreciate your comparison to other dongle DACs and how the M15 maintains its clarity and fidelity. We are glad that it adapts effortlessly to different headphones and that you are thoroughly enjoying using it. Thank you for choosing The Audio Store!
This amp dac is a mini power house. As mentioned by other reviewers, it can get really loud and can easily power 300 Ohms headphones like Sennheiser HD 650 and HD 600 etc.
Only nitpick would be the lack of custom EQ options, which are present in similar priced units like Lotoo Paw S2. However, just based on sound quality alone, it is indeed head and shoulders above the competition. It's battery consumption on my Samsung Galaxy S22 ultra is decent enough and doesn't seem to drain out battery. Overall, a worthy buy.
Thanks for the review! We're glad to hear that this little amp dac is a powerhouse, and the lack of EQ options is a minor quibble - in our opinion, the sound quality is worth the price. We hope you enjoy it!
Couldn't believe my ears. What a tremendous improvement from my previous DAC. My search ends here. I don't need to look for any alternative.
And the product is delivered in less than 24 hours. Thanks TAS for this great product and your superfast delivery.
Thanks for the kind words! We're glad you're enjoying your Questyle M15 Portable DAC & Amp.
In one word it is the one to beat. The sound is so subtle, so articulate so precise. Wait, it is for the connoisseurs of quality audio. You need to walk hundreds of miles to arrive at this destination.
Thank you for your review! We're glad you're enjoying the Questyle M15.
This is by far the best portable dac I’ve heard
In fact it sounds even better than the higher tier DAP
The sound is neutral, The treble is extended without being sharp or fatiguing
Needs some burn in initially to open up
Thanks to pritam for suggesting this gem
I’m truly loving this one
Highly Recommended

From Blon bl2 to BGVP DN2
The jump on dunu was really worth it
Almost every genre songs this IEM drive at another level of dept n separation
Only flaw i could pin point some jpop heavy electric or high pinch voice of singers was little intolerable but other than it skillet and every other genre it nail it..
Accesories are another level really feel like worth the price and best customer care...
Tried every format from flac mqa to dsd . movies or series or anime . this earphone r all in one.
Bass timing silent timing Treble timing is all so perfectly tune (tried on LGV50)

If 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.
