Till now I have enjoyed and owned a bag full of DAC. I dislike DAP. So my quest for a dac has continued for last 10yrs. I have fiio btr5, ifi signature black, mojo1, earman sparrow, ifi go blu, cayin RU7. All of them are good in there own strength.
Finally, thanks to TAS and Mr. Pritamji, I got the suggestion of Questyle cma 18. Honestly very few reviews online till now. Technical details promised a great product. Questyle 15,the baby brother,had proved it's mantle as an extremely popular dongle DAC. After going through a long thread of discussion on questyle 18, I decided to go for this pricy DAC.
Pros:
1. Very beautiful and pleasing built. Visible circuit gives an unique professional look.
2. Balanced end sound is almost uncoloured and flat. Base is great and tight. Sound stage is huge. Detailed and airy. Matches excellent with my 64audio volur, focal clear, focal Radiance. Apple music sounds great. Every headphone and earphone get a new breath of life.
3. Bluetooth LDAC and aptx adaptive is so good, sounds almost like wired mode.
4. Battery is solid 5hr+ with high gain. Source Battery not drained.
Cons:
1.Modes and displays are bit tiny for for a 40+eye sight.
2. No way track change or play pause can be done from the device.
3. Gets slightly warm.
4. At 25% Battery usb mode gets disconnected for some unknown reasons.
Overall a great device. If price drops to 40K it will smash everything in below a lakh range. Mojo ,ifi and fiio ....be careful Questyle is on top now.
A solid 5star.

It's an interesting product. I like all the tip options in this pack. It's a good beginner pack to know how each tip material can affect the sound quality. All the tip material & quality are good. The silicone tips & foam tips in the pack are good, like those stock tips we get with IEM. But the surprising tips are the latex tip & the hybrid foam tip. Although the latex tip feels a little rubbery in feel & is a dust magnet, but it's very comfortable, provides a good seal and does enhance bass & treble response slightly. And for the hybrid tip, it's like best of both worlds. It gives the comfort of a silicone tip as well as provides the seal of a foam tip. I'm not a big fan of foam tip in general because of how they feel in ear & it's very difficult to put them in the ear, but these hybrid tips removed all those problems for me.

This is one of the best modular cables I have ever seen in this price range. Microphonic is there as the nylon type of material is used for wrapping the cable. But microphonic is very minimal compared to other similar cable I have used. But, once the music starts playing, the microphonic would be gone. connector quality is very premium, on both the 3.5 / 4.4 termination as well as at 2-pin connector end. I love how easy is to replace the 3.5 & 4.4 end. It's highly recommended if you are looking for any premium modular cable on budget. It's one of my favorite modular cables along with the Moondrop aria 2's stock modular cable.

Sounds exactly like the Salnotes Zero with a bit more bass. Has that same Harman curve with upper midrange bump and reduced lower mids making male vocals sound thin. Good resolution/detail and treble is perfectly done. Fit is good and I like that these are very light.

I have own onix aplha as a dac and this is definitely a upgrade in that regards

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.

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.

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.

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.
