Description
Introduction
GATE, a cost-effective dynamic driver in-ear headphones, adopts an N52 magnet double-cavity internal magnetic circuit dynamic driver and a brand-new carbon LCP high-rigidity diaphragm. It features a redesigned cavity ID, high-quality oxygen-free copper cable, and excellent objective indicators.
Innovative Design and Comfort
The GATE is designed as a cost-effective and comfortable IEM. Its appearance has been redesigned, the cavity weight has been reduced, and the diaphragm and acoustic structure of the driver have been further optimized. The 0.78mm 2pin interchangeable design offers convenience and expanded playability.
Drivers
GATE uses a 10MM internal magnetic circuit dynamic driver with frontal-cavity filter optimization and diaphragm specialization, optimizing the structure and diaphragm rigidity.
Advanced Diaphragm Material
The new carbon LCP diaphragm material in GATE makes it more rigid than standard LCP diaphragms, improving high-frequency sensitivity. The ultra-thin PU enhances the bass texture and ensures safe diaphragm operation.
Optimized Structure
The structural strength has been optimized to fully utilize the acoustic characteristics of the new diaphragm while minimizing the deformation of the 10mm speaker during metal stamping. This ensures consistent production and acoustics.
Lightweight Coil
A large CCAW ultra-thin coil ensures a lightweight and reliable suspension system.
Excellent Objective Indicators
The GATE features a brand-new diaphragm material and optimized acoustic structure, resulting in minimal linear distortion and improved high-frequency extension compared to previous models. It ensures excellent frequency-amplitude response with HRTF characteristics, delivering a balanced, durable, and enjoyable sound with reasonable bass gains.
Furthermore, the GATE exhibits exceptional nonlinear distortion, with measured distortion in most frequency bands being less than 0.2% under non-anechoic room and 104dB SPL. This results in a clean background and allows for personalized EQ adjustments without any negative effects.
Snug Fit with Brand-New ID Design
The GATE's cavity design has been fine-tuned based on HOLA, optimizing the appearance with a transparent faceplate. The PC+ABS composite injection cavity ensures a lightweight yet stable structure. New ear tips provide admirable listening and minimize discomfort, enhancing the audio experience.
High-Quality Oxygen-Free Cable
GATE ships with a multi-core high-quality oxygen-free copper cable, featuring a 2pin thick-twisted-pair with high-quality cable skin for a tangle-free experience. It combines with a universal 0.78mm 2pin socket (female sunken type) for convenient and reliable usage.

I'm using first time DAC most of the people refer this varient, difference between 3.5mm jac and this DAC D07 is absolutely awesome, so much details in hearing a song and music, loved it ❤️❤️❤️❤️👌👌👌🙏🙏🙏
Solid pouch
With good space
The product is worth the money
And I personally love the your faster delivery service
I got the product just in with 30 Hrs

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 🙏🙏

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.
