The carry case is spacious enough for keeping one IEM and one small portable DAC with cable. Like I have kept Muse M4 dac with dihifi cable and one IEM in it. And the shell is hard so no chance of anything happening to the IEMs.
Was the cheapest option for a replacement cable I could find anywhere. And it works flawlessly too, no complaints
Amazing product
I recently purchased the Castor Pro KC earphones, and they have exceeded my expectations. The bass is deep and punchy, yet it doesn't overpower the mids and highs, ensuring excellent instrument separation. The tuning switches offer great flexibility, allowing me to customize the sound signature to my preference. Build quality is solid, and they are comfortable for long listening sessions. Overall, these IEMs deliver an impressive audio experience at their price point!

Very good cable
Works with 0.78mm 2pin iems
Using LG g8x thinq and output is higher than the smartphone's 3.5mm output.
Moondrop Link app works well, except a few buggy connectivity issues.
Good to see that one can create any Eq profile and save it in the app as long as it's done within the parameters. Very well executed.

Solid pouch
With good space
The product is worth the money
And I personally love the your faster delivery service

I like Moondrop ECHO-A Dac. It is not powerful Dac but it produces quality sound .

Great for listening to all music genres, gaming on PC or consoles or pretty much any thing you'd like to do with a pair of earphones.
Superb packaging 👍🏻 delivered what was promised.

I recently got my hands on the ROSESELSA AURORA Ultra IEM, and I must say, it has exceeded my expectations! For under 2,000 INR, this IEM delivers exceptional value and performance that can easily compete with many pricier models out there.
What really stands out to me is its versatility. The AURORA shines across all genres, whether I'm diving into classical symphonies, jamming to rock anthems, or vibing with electronic beats. The sound quality is simply fantastic, making every listening session a joy.
A cherry on top is the comfort factor—these IEMs are small and lightweight, so they don’t cause any discomfort during long listening sessions. If you’ve had issues with larger IEM shells in the past, you’ll find the AURORA to be a perfect fit. Plus, the cable quality is impressive for the price, adding to the overall value of this product.
To unlock the full potential of these IEMs, I highly recommend investing in an external dongle. I personally use the Kiwi Ear Allegro Mini DAC, and it has truly elevated my audio experience. If you're on the hunt for a budget-friendly IEM that doesn’t compromise on sound quality, the ROSESELSA AURORA is a must-try!
I also want to take a moment to thank the audio store for their outstanding service. My order arrived in perfect condition, and their customer support team was incredibly friendly and helpful. Overall, this has been a wonderful experience, and I’m absolutely thrilled with my purchase!
As a v16 owner this is a worthy upgrade .
Fit :
The iem is designed aesthetically that it fits like custom made
Sound impressions :
Treble is perfectly done with being sibilant, Mids sounds very organic and clear, Bass is the best part here it's a step up from their previous flagship v16.
Staging is better and so is the resolution, A total flagship level iem which punches above the price tag
Thanks to Pritam for his exceptional customer service and deal .
Definitely recommended

Have a great features and I am very happy after buying this m71 thanks audio store 🙏🙏
