Some online product selling giants didn't understand how to package product because it delegate and wants to handle with care and I really appreciate your customer support thank you great product delivery app in reasonable rate

It’s a neat dongle with crisp sounding music, it’s on a brighter side of music

one of the best earbuds in this price range.

As a beginner audiophile I did research on all budget IEMs but this KZ EDC Pro stood out in all reviews as best and most affordable no-nonsense IEM without distortion in sound output that drew my attention to it. And I am glad I made the choice, this deserves every bit of praise for the price & sound output better than my 5000INR TWS from reputed brands, a little bit EQ Tweaks just enhances the experience multifold... Must but for those who looking for affordable yet best sounding wired earphones/IEM. Brilliant build and sound quality for the price. A Must buy on a tight budget, and Thanks to audiostore for delivering package before scheduled delivery time.

Great DAC for the price in terms of build and aesthetic. When paired with a good IEM definitely makes the experience worth investing. Just go for it, must buy for a beginner/intermediate audiophile...!

Easy blind buy for the price. Most recommended set of iems if you're new to the iem community and are looking for something under 5000 rupees. Sounds clean and has a lot of customisation options with app support.

good sound and clear even without the dac and anything haven't tuned anything still clear sound!

After having owned a few kilo-buck IEMs, I was prepared to get something that was insane and probably endgame and rightly so Pritam sir recommended the FIR audio Xenon 6 and thus deep dived into this and I am sure this would be the end game IEM for me.
The XE6 is so wonderfully crafted looks like piece of jewelry and although a large IEM it is very comfortable for me for long sessions.
It sounded good from the start and was really different from the other IEMs. It started to sound even better and grew on to be the best I ever heard after listening to it for longer. I paired with Astell&Kern SP3000T and Hiby rs8 II and with desktop DAC Amps (FiiO K19, Topping D70. A70, Hifiman R2R and Xduoo TA 22) and the immersive, warm, musical and soundstage that filled my head all over. The sub bass is where it stands out the most, but the mids and highs are also so clear and crisp. I havent yet tried to change the atom modules as yet, I am sure this will make the XE6 even more great than that it already is.
The shells in the IEM I were crafted in the US (was crafted in China earlier, but as Trump wanted his MAGA force it had to be made in the US now)
This is definitely end game worthy!!!!

I’ve been using the Moondrop Chu 2 for around 5 months, and I’m really happy with them overall. The size is very good – small, lightweight, and comfortable for long sessions. They fit well in the ears and don’t feel bulky at all.
In terms of sound, they’re excellent for the price. Clear mids, detailed highs, and a balanced tuning that works great for vocals and instruments. They still feel solid and well-built even after months of daily use.
The only drawback is the bass – while it’s clean and controlled, it’s not very strong. If you’re looking for heavy bass, these might not fully satisfy you.
But if you want clarity, balance, and detail in a compact design, the Chu 2 are a fantastic choice.

Very good value for its price range,
Solid build, durable metal shells
Comfortable fit and decent ergonomics
Tuning flexibility thanks to interchangeable nozzles
Soundstage depth isn’t exceptional (though width / height are decent)
The black nozzle for brighter tuning is a bit aggressive.

This is my first IEM..so I'm not knowledgeable enough to decide if it's the best or not..but definitely a good buy..go for it guys..and don't forget to pair it up with a good dac....

I got these cables for my CHU II because I broke the stock cable.
For the following reasons I would say it's a solid recommendation for it's price.
The cables themselves are not as heavy as they might look and more importantly, they are not "stiff, ear hooks are also fairly comfortable.
Also, they don't particularly retain shapes and seem to be freer and tangle free.
The quality on the cables is good, it's been almost two weeks, and I haven't seen any quality issues come out.
The mic quality on calls is decent, very serviceable.
Don't expect upgrade cables to change the tonality of your IEMs.
These don't have a chin-slider, I would have loved to see that.
(THE COOLEST PART, they include a free hard case and tbf it's actually a good case better than some listed even for around 300INR out there)

Tuned like a blessing formy ears, Go for it

I use the moondrop free dsp mini with my hidizs mp145 planar iems and the response is amazing. Micro details are good mids are just right. The bass is tight. You'll love it.

After searching for around 7 days, I finally ordered these. I have received them just an hour ago. Will update the review in few days. Initial impressions are too good.
