It supports iOS, HarmonyOS, and Android versions 5.1 and above, as well as PC systems running Windows 10 version 18.3 and above (driver-free) and Mac OS. This broad compatibility allows Hi-Fi headphone users to enjoy lossless audio on streaming platforms seamlessly.
Apple MFi Certification for Enhanced Performance
The "i" in M15i signifies its Apple MFi certification, ensuring perfect compatibility with iPhone/iPad and the broader Apple ecosystem. This certification guarantees that the M15i meets Apple's strict standards for power consumption and compatibility, safeguarding your devices from potential damage caused by non-certified USB connections.
Dynamic Sampling Rate Display for Easy Monitoring
The M15i features a data status indicator that lights up during music playback. A single red indicator signifies PCM data with a sampling rate not exceeding 48kHz, while dual red indicators represent high-sampling-rate PCM data or DSD audio data. This feature allows users to easily monitor the sampling rate of their audio.

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.
