Advanced Tribrid Drivers Configuration
The Aurora utilizes a double dynamic driver system composed of 1 x 12mm large diaphragm drivers, 2x full-range balanced armature drivers, and a 6mm ultra-treble planar driver. This multi-driver design divides the frequency spectrum between multiple drivers, reducing load and enhancing output and sound quality. By using a tribrid configuration, the Aurora achieves optimal sound characteristics from each driver. It addresses common faults of hybrid or tribrid designs, such as mixed timbre characteristics, by optimizing each driver type to respective frequency ranges at softer crossovers, creating a coherent sound across the entire spectrum.
Powerful 12mm Composite Dynamic Driver
The custom 12mm composite diaphragm driver features a double coil system that significantly enhances low-end output at reduced distortion rates. Tuned specifically for bass, this driver provides well-textured and powerful lows in a controlled and professional tuning. The composite DD bass system delivers enhanced impact, speed, and texture.
Dual Balanced Armature Drivers
A custom full-range balanced armature was selected to bridge the gap between the dynamic and planar drivers. This balanced armature driver has an intermediate timbre between the two driver types and offers excellent midrange performance.
6mm Ultra-Treble Planar Driver
A 6mm diaphragm is utilized in the custom micro flat-panel planar driver to achieve ultra-treble extension for crystal clear highs. By adjusting airflow to the drivers, the Aurora achieves an excellent sense of air and micro-detail retrieval, effectively extending the treble past 40kHz.
Meticulously Balanced Tuning Profile
The Aurora is carefully tuned using a three-way passive crossover network to best display each dynamic driver’s full potential. The tuning offers a powerful bass presence at 10dB impact, smoothly transitioning to slightly warm and natural mids. The treble is clear and detailed, yet maintained under 10dB to provide a comfortable yet discerning listening experience.
Professional Manufacturing Process
The Aurora’s shell is carefully crafted using professional 3D printing with imported medical-grade UV resin. This process creates a high-precision shell that is safe for the skin, comfortable, and durable. The faceplates are composed of unique titanium filaments, creating a one-of-a-kind design for each unit.
Custom Detachable Cable
The Aurora features a detachable gold-plated single-crystal copper cable with 0.78mm 2-pin connectors, which is interchangeable. The cable includes a modular 3.5mm/4.4mm interchangeable plug system to fit any of your devices.

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.

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.
