MOONDROP Harmon IEM – Triple Dynamic Driver Precision with Acoustic Crossover Excellence
Experience next-level audiophile sound with the MOONDROP Harmon, a meticulously engineered triple dynamic driver IEM featuring Moondrop’s proprietary acoustic crossover system. Designed for precision, clarity, and rich tonal depth, Harmon integrates three full-size 10mm dynamic drivers—two dedicated to low frequencies and one for mid-treble—each housed in its own resonant acoustic chamber for superior phase alignment and low distortion performance.
True Triple Dynamic Architecture
Unlike hybrid IEMs that combine different driver types, the Harmon focuses purely on high-performance dynamic drivers. Two bass drivers are mounted in a horizontally opposed configuration to eliminate unwanted mechanical vibrations while delivering deep, punchy, and tightly controlled bass. A specialized mid-treble driver, featuring a 1μm-thin glass dome diaphragm, ensures extended treble response, accurate imaging, and natural tonality—without harshness or fatigue.
Advanced Four-Cavity Acoustic Crossover
At the core of the Harmon lies a patented four-cavity coaxial crossover system, which relies on precise acoustic filtering rather than heavy-handed electronics. This approach guarantees phase-coherent sound across all frequency bands, creating a more lifelike and immersive soundstage with incredible detail resolution.
VDSF Target Tuning with Real-Ear Refinement
Harmon is tuned according to Moondrop’s VDSF target, based on B&K HRTF data, and further refined with real-ear testing to achieve an exceptional balance between analytical detail and musical warmth. Whether you're listening to classical, jazz, electronic, or rock, Harmon delivers a full-bodied, emotionally engaging sound signature.
Extremely Low Distortion Performance
Even at high output levels, the Harmon maintains distortion under 0.1% at 94dB SPL, outperforming most IEMs in its class. Expect a clean, transparent presentation, ideal for both critical listening and long immersive sessions.
Premium Build with Modular Cable System
Crafted using precision 3D printing by HeyGears, the Harmon features a compact, ergonomic shell that fits comfortably. It ships with a braided detachable cable and interchangeable 3.5mm single-ended and 4.4mm balanced plugs, making it ready for any audio source without extra adapters.

It's truly velvetty- If I can say so. Good for IEM's with large nozzles .

Delivery on time, Good product, Happy to purchase overall

I own a Simgot ET142. Wanted a pure planar and my choices were the Letshouer S12Pro , 7Hz Timeless and the Sivga Nightingale.
The Sivga isn’t available in India.
The Letshouer reviews had me confused between the S12 and its upgrade the S15.
The 7Hz was a notch lower compared to the Letshouers.
Finally I decided to pitch in for the S15 considering that the audio store has a sale on it and the pricewas better than that offered on HPZ and Conceptkart and Desertkart.
I am happy with my gamble.
Bass , Mids and treble are all aligned perfectly to my preferences. A mild V shaped profile. Rich warm bass and smooth trebles without harshness.
Thank you Audio store.

Pre-ordered the Top pro and received it in a week.
IEM is Excellent
The bass is there, doesn't overwhelm but when it hits you can feel in the chest
Treble is the smoothest I've heard
Vocals are clean
Seperation is top notch

Worth.

The sound is fucking great for the price….the voices rock..bass is not over justified….balanced and provides according to track,one downside because of which I’m rating 4..is the fit…hurts my ears even after 1 hr….might adjust to different ear shapes of diff ppl..overall satisfied for the money….if u skip bass….it kills the market opponents like realme air 7 pro and one plus buds 4 also one more thing ..the case feels a bit cheap…and might get scratched ez..and since it’s quite uncommon set of buds…u don’t get any protective cases as such

TANCHJIM Bunny has an excellent sound signature to start with - clean, energetic and fun it works beautifully with jazz, R&B, hip-hop and even bollywood music. But it's possibilities just start there. Once you connect these IEMs to your phone and download the Tanchjim app, you would discover a ton of sound profiles pre-saved. There are 4-5 official sound signatures, but even more are the access to thousands of fan created sound signatures. You can tune it to any of the hundreds of IEMs available - everyday a new IEM, if you like. The play opportunities are endless. The build could be better - looks kind of cheap compared to the solid metal body of the Chu 2, but no complaints as far as sound goes.

Exceptional delivery by theaudiostore.
The packaging was really well done.
The Bunnys blew my mind when I first used it, it sounds so much clear than my Airpods Pros!
Anyone getting their first IEMs go for this!

The build quality is sturdy & good. The new design is nice. Work well without any hissing noise or heating. Using it on my CMF Phone 1 🙌✨

Adequate purchase, best sound you will hear.
Probably double volume than TWS.
Looks seriously different than other headphones I have used till now, you look different than rest of the crowd(in the gym especially), that makes you feel special 😊☺️

Must go for it Bluetooth & DAC AMP

- Audiocular SPARK DAC is one of the best looking dongle DAC I can find also the audio quality it throws it's just supirior to any normal phone or pc DAC.
-Well there is lot of DAC with same configuration but on higher price this one feels premium and it's just under 1000 bucks so I don't think so you need anything else as a beginner or anywhere for regular use it's best of best.

- I was really confused between salnotes zero 2 and moondrops chu 2. After lot of thinking and chatgpt decided to go for Chu 2 well my initial experience was not good because I was using realme airbuds 5 pro which is a great wireless earphone dual drivers but mostly bass heavy so chu 2 bass felt lacking at start but it's just initial expression once I got comfortable with it is blown my mind cause it's really well balanced you can hear good amount of sound seperation bass is good and don't leak into the other instrument details or vocals.
- I purchased it with audiocular spark DAC
And honestly it's deadly combo it improves so much sound quality and bass and on top of that the fit of chu 2 and cable is really good and with this DAC it feels aesthetically pleasing as well.

Awesome Product...

Awesome headset
