Description
Experience next-level precision, clarity, and immersion with the TANCHJIM FOLA IEM—a premium in-ear monitor engineered for audiophiles, gamers, and movie lovers who demand lifelike sound. Designed with TANCHJIM’s advanced DMT5 dynamic driver architecture, FOLA delivers exceptional energy conversion efficiency, ultra-low distortion, and a smooth frequency response that elevates every listening session.
Precision Engineering for Exceptional Sound
At the core of FOLA is a double-chamber, double-magnetic circuit dynamic driver, purpose-built to reduce distortion and deliver accurate sound across an ultra-wide 2Hz–48kHz frequency range. Paired with TANCHJIM’s flagship single-dynamic waveguide cover, it enhances high-frequency performance, offering crisp treble, excellent detail retrieval, and lifelike resolution.
Virtual 7.1/5.1 Surround for Immersive Gaming & Movies
FOLA integrates HRTF-tuned virtual 7.1/5.1 surround sound, creating a spacious, cinematic listening environment. Gamers benefit from heightened positional accuracy—spotting footsteps, gunfire, and directional cues with ease—while movie enthusiasts enjoy richer, more immersive soundscapes.
Customisable Sound Signature
Tailor your audio with FOLA’s interchangeable acoustic tubes:
-
Light Tube – enhanced clarity and detail
-
Standard Tube – balanced natural sound
-
Dynamic Tube – impactful bass and immersive warmth
This allows users to shape the sound to their taste. Included is a premium copper-plated silver Litz cable for clean, stable signal transmission.
Premium Build with Exceptional Comfort
Built with a CNC-machined aluminium alloy chassis and a sapphire glass faceplate, FOLA strikes the perfect balance between elegance and durability. The lightweight shell and ergonomic contour deliver long-lasting comfort, complemented by TANCHJIM’s T-APB air-pressure balancing eartips for reduced fatigue and a secure fit.
High-Frequency Enhancement with Waveguide Technology
The advanced waveguide cover uses FEA-optimised acoustic modelling to increase high and ultra-high frequency energy transmission by up to 10%, improving detail, clarity, and sparkle while reducing unwanted losses.
Optimised Acoustic Flow for Cleaner, Clearer Audio
A specially engineered inner chamber minimizes sound turbulence, improving vocal intelligibility and high-frequency smoothness. The semi-open back cavity enhances presence in the 5–6kHz band, adding transparency to vocals and instruments without harshness.

IEM reviewer eargasmic3060 recommended me as per my taste. I had asked for an IEM with ideal bass, neutral mids, decent detail on highs without sibilance. This IEM checked all the boxes. Very highly recommended for long non tiring listening. You shall customise your listening by tip rolling. Additionally, you shall choose nozzles based on your preference. This provides huge versatility. Overall, I'm very happy with the purchase. You shall go for it if you prefer neutral warm sound with decent highs without sibilance.
My review is based on the Standard nozzle with stock tips (narrow bore) after over 20+hrs of listening/burn-in.
Physical Features: Clean and sterile look, fingerprint magnet, lightweight and comfortable, stock tips are good, stock cable is good but very hard which can create some discomfort on the ears
Sound Signature: Clean, Balanced, Neutral, Forward Vocals, Natural Timbre
Bass: It has decent amount of bass (not bass-head type). One can feel the rumble and hear the mid-bass. Bass is focused on quality rather than quantity.
Mids: Incredible mids! Vocals are a treat to listen to. Both female and male vocals sound natural and realistic, just like real life. One of the best IEMs for Bollywood Music (since they have a lot of vocals). Mid focused instruments such as Piano/Guitar sound very realistic.
Though rarely on some tracks, mids can become a little spicy at higher volumes. Nothing such on low volumes.
Treble: Rolled off and smooth treble, little lacking in airiness, but still sounds incredible. Absolutely zero sibilance.
Technicalities/Soundstage: Another highlight of this IEM. Timbre is natural and realistic, instrument imaging and separation are simply breathtaking! The soundstage is like 3D, holographic, one can accurately pin-point where each sound is coming from. Instrument decay is natural and instruments sound lush. One can hear full notes for each instrument.
Additional Nozzles Review: Unlike many other IEMs, tuning nozzles in FOLA are not gimmick. The Dynamic nozzle makes this a warm sounding IEM reducing the mids and increasing the bass (excellent for electronic/rock music). The Light nozzle increases clarity/makes it bright (without sibilance though).
DSP/Equalization Review: This is where this IEM truly shines! The ability of this IEM (and its dynamic driver) to take on equalization is incredible. It is as if Tanchjim gives us a neutral IEM out of the box and asks us to tune it according to our taste. If one wants to change the sound signature, one can simply use some equalization software (Tanchjim has its own for Windows/Android but any equalization works well enough).
With the help of equalization one can convert FOLA to sound like other IEMS (warm/dark/fun/bright...etc) without compromising on the excellent technicalities it provides. The audio after equalization doesn't sound equalized, it feels as if it was the default sound signature of the IEM.
Gaming/Movie Review: The standard nozzle works best for this. Due to the 3D soundstage, gaming is a treat. One can accurately pinpoint the smallest of sounds in the 3D space. Movies feel immersive and with Dynamic nozzles almost feels like sitting in a theatre with surround sound.
Overall Review: FOLA is what we can call a truly versatile IEM. Its ability to take on equalization and convert its sound signature makes it a jack of all trades and also a master of all trades. An absolute buy within the mid-tier budget range!
Something different sounding earphone with good tactile bass and effective overall

I was impressed by fast and well managed delivery 📦 . Coming to moondrop space travel 2 ultra..one word awesome..I was searching for tws loud enough and quality sound and I am fully amazed by sound.
Very best audio quality each and every vocal was crisp and clear in future I will buy more Iem from audio store❤️
After using the Roseselsa Aurora, I can confidently say it's one of the best budget IEMs I've tried. The tuning is fun, vocals are detailed, the bass has good impact, and instrument separation is impressive. It's comfortable, well-built, and makes every song enjoyable. Definitely worth buying if you're looking for a quality IEM. 🎧⭐⭐⭐⭐⭐
Nice dac
I've purchased this kz edx pro 2 with mic and type c I've received in just 2 days and the product is absolute perfect and build quality and audio experience is so good I've loved it and the look also is so good, the quality of mic is good though compare to other mics audio is perfect and smooth for me.
I opened it fastly then at the end i saw take a video while opening sorry audio store. But tbh the wire quality is so good and delivery also came before expected date. If someone reading this comment the 1 reason to buy from audio store is they keep affrodable prices when compared to headphonezone and concept kart and offcourse amazon and the quality is also on top notch
Great little DAC! Clean, detailed sound with better clarity, tighter bass, and good instrument separation. Compact, easy to use, and a solid upgrade for any IEM.
My first pair of IEM and I absolutely loved it🥰
I’ll recommend the audio store and purchase more in future
The product has a sturdy build and the ring light adds a clean, aesthetic touch that enhances its overall look. Using it with my KZ Castor Harmon Edition feels like listening to my favorite song for the very first time, with sound quality that is clear and immersive. It works smoothly with both Samsung devices and Windows, and the customization options on Windows make it highly versatile. The quick delivery in just one day was the icing on the cake, making this a well-rounded purchase that combines design, performance, and convenience.
Pairing this Harman Target Version with a Samsung A17 playing Apple Music and FLAC files and Fiio X1 DAP as a secondary source with FLAC files. When tuned to give preference to Mids as i prefer to hear the voices more than anything else, this comes out as a sweet sounding combination and tracks like Racy Chapmans Fast Car and Massive Attacks Teardrop shine beautifully. The Castor Pros are best listened at about 40% volume and and infact they do actually sound amazing at a high volume for bass heavy tracks such as EDM but for Trance and Rock the cymbals and snare drums sound better at 40%. This pair of iems and the combo sounds like money well spent so far and next i want to try analytical IEMs like the 7Hz. Thanks to the Audio Store for the rushed delivery.
Great purchase... excellent product
Good Product as expected
This is a good dac
Worth every penny! This is not for bassheads as it lacks just a bit on the bass department, but the separation is awesome and the sound stage is also huge. Awesome for gaming as well! (Apex Legends, Arc Raiders, PUBG)
This is the replacement for my purchase of moon drop dsp chu2 which I bought in aug 2025 i don't know how it got damaged from last it stopped working on left side buds and after a few days mic also stopped working and i forgot to claim the warranty for it . So find this spare cable very helpful since I love these IEMS for real Tq AUDIO STORETEAM FOR THE smooth delivery
