was kinda in the middle before ordering this as i didnt knew what to expect at this price but damn its awesome
It is really really good and the vocals clarity is much more higher than the traditional default 3.5mm ports of smartphones. I think, it is a great investment.
I purchased this DAC jack after multiple failed attempts with other usb C to 3.5 mm converter for my samsung s24 ultra phone.
I was almost about to loose my wired music connectivity but this one saved me and I am really happy.As per Price segment it is the best one.
Dont expect very much abput frequency responses with this tiny DAC but up to maximum all average audions it will satify with its robust build and performance.There is no nonsense with this DAc like extra distortion,hissing sound.
Kudos to AudioStore's People to just satisfy my quench with lot of patiences.
Finally I bought one more product form them.It was really amazing experience with Audio Store Visit.
Worth for the money
Its geat, the build quality is nice, the wire is preety hard.And quality is sick

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.

The Audiocular C03 is an exceptional value for money upgrade cable in the market with a decent mike and in line controls along with amazing build quality thank you The Audio Store for fast Delivery

Good for Gaming and Multimedia both

these iems are so clear with wide soundstage and these are small and lightweight and sits flat in ear without building out if u use small tips according to your ear , this is my second iem the first one was kz edx and it was bass heavy after listening to this , i find out that this is what we call iem neutral soundstage. this dsp version allows you to set a fix eq to the dsp and now you can use same eq anywhere you want if it is laptop or tablet or pc without installing an eq software, the app also have community driven eq sharing where individuals can share there eqs you can pick eqs from there to suit your preference

It is really really good and the vocals clarity is much more higher than the traditional default 3.5mm ports of smartphones. I think, it is a great investment.

Anc & Transparency mode nice, Battery hrs fullfill & Mic quality top notch,
Soft touch Key function.

Best IEM under 5K. You'll be surprised by the value you're getting.

It's a great and adorable dac at the same time. It fulfills the need without a heavy toll on the pocket.It comes with a 3.5mm to type C converter with High res and moreover a Usb C to A converter.

While I wouldn’t call myself an audiophile, the Moondrop Space Travel 2 delivers an impressive listening experience that exceeds expectations at this price point. The sound is clean and well balanced, with excellent clarity and instrument separation. Bass is present but not overpowering, and the overall loudness feels well tuned. My only real criticism lies with the case that is the open-top design makes handling the earbuds a little fiddly, and there’s a learning curve to inserting and removing them smoothly.

crisp details and decent bass. overall, perfectly balanced sound. loving it. Also kudos to the quick one day delivery.

This is my first IEM and kz did an wonderful job making this piece of beauty, paired along with a dac it's even better, the lows are good, the mids and highs are even better, the stereo seperation and audio quality is much better than my previous tws. This tws even got a control switch, if you're an audiophile then this would make a difference you'll feel it, but to other people who uses casually not much of a difference they'll feel, the iem feels premium and the wire quality is good. Lastly thanks audio store for providing this at one of the lowest prices where on other platform this ain't even available, the packaging was excellent and even if the outer cardboard box got a bit deformed but inside the product box were perfect so 10/10 on packaging. The quality of headphones 8.5/10, the quality of the audiocular dac I ordered with this iem 8/10. Overall go for this iem at this price range this is a beast.

It's warm/bassy sound is what I like the most. The emphasis is more on sub bass but also not in ur face. Mid bass also sounds clean without being shouty. Treble is really smooth with slight sparkle which is great if ur treble sensitive. I can listen to these for hours at work without being distracted or fatigue. Good fit and build quality. Any genre sounds good on this iem.
