Craft Ears Aurum – Flagship Tribrid IEM
The Craft Ears Aurum is the crown jewel of the Genesis Series and the ultimate expression of our pursuit of perfect sound. Named after Aurum—Latin for “gold”—this flagship IEM embodies brilliance, refinement, and musical purity. Designed for audiophiles who demand nothing less than the best, Aurum delivers a breathtaking listening experience that blends cutting-edge technology with natural musicality.
Sound from the Soul
Aurum is our first tribrid IEM, integrating:
-
A specially engineered 10 mm PEN dynamic driver for powerful, visceral sub-bass.
-
Four balanced armature drivers for rich mids and articulate highs.
-
Two Sonion electrostatic drivers for sparkling, ultra-refined treble extension.
The result is a sound signature that is immersive, balanced, and highly detailed. With expansive staging, holographic imaging, and jaw-dropping extension on both ends, Aurum sets a new benchmark for high-end IEMs.
Sonic Performance
-
Bass: Deep, textured, and controlled. Sub-bass rumbles with authority, while mid-bass stays impactful yet never bloated.
-
Mids: Natural, smooth, and emotionally engaging. Vocals shine with realism and depth.
-
Highs: Airy, refined, and effortlessly extended. Cymbals and ultra-high frequencies are rendered with lifelike clarity and smoothness.
-
Soundstage & Imaging: Wide, spacious, and precise with excellent separation, creating a true holographic presentation.
Exclusive Technologies
Craft Ears Aurum achieves its performance through innovations never seen before:
-
SES™ 2.0 (Space Expanse System) – A patent-pending, 3D-printed horn-loaded tweeter for enhanced EST driver performance, delivering cleaner, more expansive treble.
-
True Load™ Technology – Maintains extremely flat impedance and phase response, ensuring perfect driver coherence across the frequency spectrum.
-
5-Way Crossover Design – Seamlessly integrates all seven drivers for an effortless, natural sound.
The Craft Ears Aurum is not just an IEM—it is a statement of craftsmanship, technology, and passion, designed for those who seek the very essence of sound.

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.
As redditors said its good. But might be boring at initial iem try. App has lot of EQs to tweak and play
I would like to thank Purecast & Pritam ...I was not sure if this was required. I however noticed it's not a normal dac it's a DAC Amp so it also amplifies sound...it comes in a cool packaging with cover and I am thankful that Audiocular was thoughtful to add a typeC to Type A convertor as I am using this mainly in my Dell laptop. Thanks Audiocular.
Bought the Moondrop Dawn Pro Balanced DAC/AMP recently. Build feels premium with a sleek metal body, swappable 3.5 mm & 4.4 mm outputs, plus handy volume buttons. Noticed extra loudness and a subtle but clear improvement in my IEMs. For the price, totally worth it! 🎶
I used lots of earphones and earbuds, neckband but this IEMs sound is different unbelievable I loved it Thanks 👍🏻
Excellent product. Super premium and sounds balanced.
THE HEADPHONE IS ONE OF THE BEST WHICH DOESN'T NEED ANY TEST BECAUSE ITS THE BEST, THE BLUETOOTH RANGE IS SO LONG THAT ONCE I FORGOT MY MOBILE WHILE GOING TO MARS , NORMAL HEADPHONE WILL DISCONNECT IN THAT RANGE ABOUT 33.9 MILES BUT THEN ALSO THE HEADPHONE DOESN'T DISCONNECTED AND THE MUSIC WAS STILL PLAYING NOW I WAS COMING BACK FROM MARS AND TYPED THE REVEIW WITH MY BARE HANDS 😀
Although termed as Basshead, it's clean and crisp. Bass knows when to punch and when to calm. Upgrading from Juzear Defiant which is itself a great allrounder to its price. Thoroughly enjoying the Martilo. Finally great service by TAS. Looking forward for more.
good build qualityand High quality audio output
Absolutely a beast, had to wait since it was out of stock. This is the best under 3K and probably the best with Mic under 5k.
If you are a beginner audiophile and wanted to invest friendly budget IEM then EarAcoustic STA-Hi End Series IEM is a way to go. The sound is awesome and you can hear every node it contains.
It is the best and clean sounding IEM, perfect for the Beginner.
I love the fact that I can change the nozzle and its a little different sounding, so its two in one.
The cable quality is out of the world no external sound when I touch it.
I can hear so many details clearly. I say please go for this, it is perfect first IEM and the Perfect Upgrade if you had IEM under 2k before
It provides Awesome sound quality go and buy it m
🎧 KZ Castor Pro IEM – Review
🔊 Sound Quality
The KZ Castor Pro delivers clear and detailed sound with excellent separation across lows, mids, and highs. The decent thumping bass is tight and controlled, giving energy to tracks without overwhelming the vocals or instruments. Its super-balanced tuning ensures a natural, enjoyable listening experience suitable for all genres.
🎚 Unique DIP Switch Equalizer
What sets the Castor Pro apart is its DIP switch physical equalizer. With up to 16 different tuning options, it allows listeners to adjust the sound profile on the go—boosting bass, enhancing treble, or keeping it neutral. This feature gives it a level of flexibility rarely seen in IEMs at this price point.
🔇 Noise Isolation
Although it lacks active noise cancellation, the design offers an excellent passive seal. The snug fit ensures that outside noise is effectively blocked, making the listening experience immersive and ensuring ANC doesn’t feel like a missing feature.
🎼 Hi-Res & DAC Performance
For those using Hi-Res lossless audio, pairing the Castor Pro with a DAC is highly recommended. The extra power and clarity from a DAC enhance the already impressive soundstage, detail retrieval, and overall dynamics, making the listening experience truly premium.
💰 Value for Money
At its smart price, the KZ Castor Pro punches well above its weight. It combines detailed sound, punchy bass, balanced tuning, and innovative features—making it a strong choice for both audiophiles on a budget and everyday music lovers.
Have been using these buds for like an year now, they gave me a great time all that while, only recently the cable started getting green and there was an issue with audio drop on even a slight movement (like every earphone ever), but still a great investment for an year.
