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 🙏🙏

Time Spent with this DAP is more than 50 days, used many IEMs from Budget range to high end.
OBSERVATION & EXPERIENCE SO FAR.
- Wide soundstage, it's creating a spacious listening experience.
- Smooth and refined sound, with good bass & trebles. I liked it.
- little high Volume doesn't hurt ears because of spaciousness which this DAP creates.
- Main unique point is Vocals & Instruments separation, it's best.
- So far, I noticed Battery back up is really good. Will check it over time and provide feedback.
- Does not get warm that too after using for hours.
- Best software & Shanling Music app, it's very fast ( I use 1TB fully loaded Micro SD card.)
Please Note - Little more care is needed while handling as it has Glass tubes. Again it's unique offering & tubes makes music more enjoyable.
CONS-
1. Charging time ( it will get solve by software updates in future, Brand has co
nfirmed it in their post)
2. Only one colour option is available from Brand.
3. Some settings currently not present, Brand may add in future updates ( DSD gain Compensation, PEQ, MSEB, Night light short cut in quick pannel)
CONCLUSION-
a. Highly recommend those who want detailed & immersive experience.
b. THREE IN ONE- One DAP but three modes, all three sounds differently. One mode Transistor (without Tubes) and two Tube modes (Triode & Ultra- linear).

Sterdy & beautiful cable. I am using it with Hidiz MP145 Planner Magnetic IEM. It add details to music over stock cable. Makes all aspect of sound quality better.

I am writing review after One month regularly uses with my two DAP - Shanling M8t, Hiby R4.
POSITIVES-
1. Best Soundstage
2. Balanced sound
3. Musical & Makes music more enjoyable to ears.
4. No fatigue despite of metal construct.
5. Weight distribution is really good.
6. Largest Magnetic planner in the Category.
7. Details & instruments separation at best.
CONS-
1. Small ears may face challenge. Plz contact team ATS before purchase. Normal ear size, No issues with fit & long usage.
2. Stock cable is good but doesn't suit this IEM.
I am using this with Divinus Auram cable, which goes really well with this by appearance as well as by performance.
CONCLUSION-
1. Very very happy with the purchase. It's my main IEM in daily music journey.
2. My suggestion is Music enthusiast must have atleast one 'Planner Magnetic IEM', believe me I found that the the songs which I am listening since decades are sounding differently with some more details with this IEM.

The KZ Castor is an excellent choice for budget audiophiles. It delivers superb sound quality that rivals much more expensive headphones, with clear highs, rich mids, and deep bass. The build quality is solid, offering both durability and comfort for long listening sessions. At its price, it’s a fantastic value, outperforming many premium options. Highly recommended!

i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service
