Description
Enjoy reference-grade sound from the 64Audio Trió. This gorgeous IEM is fitted with 1 dynamic driver and 2 balanced armatures for a smooth sound signature. The incredible LID, tia and Apex Core technologies enhance the laid-back playback and immersive 3-dimensional feel in your music.
Say ‘No’ to Distortion with tia
The 64Audio Trió’s patented Tubeless In-Ear Audio (tia) system reduces unwanted resonance and distortion for a transparent and lifelike sound. This is achieved by allowing the single dynamic driver and 2 tia balanced armature drivers to radiate freely in the single large tia bore with no obstructions in front of the drivers. It features special acoustic chambers instead of tubes that constrict the sound of the drivers.
The Apex IEM
The Air Pressure Exchange (Apex) Core allows a seamless airflow and is fitted through the entire solid aluminium shell. A perforated grill on the elegant brushed aluminium faceplate prevents the obstruction of air for the effortless reproduction of music. This patented vent releases air pressure for better comfort and lesser fatigue while enhancing noise isolation that’s similar to the m15 module.
Pick Any Source Device with LID
The different source amplifier output impedances of smartphones, DAC/Amps, Hi-Res Audio Players and more, can cause the frequency response to vary across devices based on the increase in resistance. A patented Linear Impedance Design (LID) circuit corrects the non-linear electrical resistance of the multiple driver-sets to restore proper interaction with the source device. It preserves the desired sound signature while staying constant and reliable.

I got the Trio as an upgrade to my ThieAudio Monarch MKIIs. The Trio is a fantastic step up and superb IEM that complements (and trumps) the MMKII. I couldn’t agree more with 64 Audio’s definition of the Trio when they say that it is a perfect balance of analytical reference sound that’s also dynamic, fun, and engaging while being extremely comfortable for long hours of listening (thanks to the compact size and APEX). It presents a sweet spot between reference-level clarity and a smooth sound signature for extended listening. It is a light IEM and extremely well-built. And believe me, APEX makes an enormous difference. It causes almost no fatigue and pressure build-up in my ears and makes the listening experience even more relaxed. The imaging and soundstage are also top-notch as I can hear each individual instrument's sound and where it is playing from on the stage. I am using the Trio paired with my Qudelix 5k and Shanling UA3. My next plan is to upgrade to a balanced cable. On the topic of cables, if there's one thing that I disliked, it is the absence of a Balanced Cable after paying so much. 64 Audio can surely do better for the money they are charging for this IEM.
One more thing- initially I had planned to buy the U12T but after auditioning it, I realized that I prefer a hybrid drivers-based setup instead of an all-BA drivers-based one. Hence, I strongly recommend that you try out various IEMs before paying so much money.
In a collection of many big hitters, I find Trio to be my best IEM. It has the sweet spot between musicality and reference tuning, and the bass is quick and tight.
Holographic soundstage adds to the magic.

This is my first IEM, and coming from Sony MDR 7506 and Airpods Pro i feel this sounds more richer and detailed.

It was great purchase and I'm happy from the output of this one. And as much as i love music , i have specific demands to meet like well balanced mids and highs but also good punchy bass. I'm happy with this purchase and i love it.

This was my first purchase from The Audio Store, and I was a bit hesitant at first, but they proved me wrong! The whole process was seamless, and I even received my order earlier than expected. The IEMs are really good and totally worth the money.
If this is your pick than go for it blindly!!!👌🎧

These are a great pick if you love a balanced sound. The best thing about them is the vocals — clear, natural, and full of emotion. You can really feel the singer’s presence without any sharpness or muddiness. Everything just sounds right, especially for long listening sessions.

Audiocular packaging is premium always give a small pouch which can be very handy.Initially Right side was not working in my KZ Harman target Balanced version. Date Recd 7th Oct 2025! every thing is awesome Love Pritam for being Down to earth.I am going crazy at age 51 with this music world man

Some online product selling giants didn't understand how to package product because it delegate and wants to handle with care and I really appreciate your customer support thank you great product delivery app in reasonable rate

It’s a neat dongle with crisp sounding music, it’s on a brighter side of music

one of the best earbuds in this price range.

As a beginner audiophile I did research on all budget IEMs but this KZ EDC Pro stood out in all reviews as best and most affordable no-nonsense IEM without distortion in sound output that drew my attention to it. And I am glad I made the choice, this deserves every bit of praise for the price & sound output better than my 5000INR TWS from reputed brands, a little bit EQ Tweaks just enhances the experience multifold... Must but for those who looking for affordable yet best sounding wired earphones/IEM. Brilliant build and sound quality for the price. A Must buy on a tight budget, and Thanks to audiostore for delivering package before scheduled delivery time.

Great DAC for the price in terms of build and aesthetic. When paired with a good IEM definitely makes the experience worth investing. Just go for it, must buy for a beginner/intermediate audiophile...!

Easy blind buy for the price. Most recommended set of iems if you're new to the iem community and are looking for something under 5000 rupees. Sounds clean and has a lot of customisation options with app support.

good sound and clear even without the dac and anything haven't tuned anything still clear sound!

After having owned a few kilo-buck IEMs, I was prepared to get something that was insane and probably endgame and rightly so Pritam sir recommended the FIR audio Xenon 6 and thus deep dived into this and I am sure this would be the end game IEM for me.
The XE6 is so wonderfully crafted looks like piece of jewelry and although a large IEM it is very comfortable for me for long sessions.
It sounded good from the start and was really different from the other IEMs. It started to sound even better and grew on to be the best I ever heard after listening to it for longer. I paired with Astell&Kern SP3000T and Hiby rs8 II and with desktop DAC Amps (FiiO K19, Topping D70. A70, Hifiman R2R and Xduoo TA 22) and the immersive, warm, musical and soundstage that filled my head all over. The sub bass is where it stands out the most, but the mids and highs are also so clear and crisp. I havent yet tried to change the atom modules as yet, I am sure this will make the XE6 even more great than that it already is.
The shells in the IEM I were crafted in the US (was crafted in China earlier, but as Trump wanted his MAGA force it had to be made in the US now)
This is definitely end game worthy!!!!

I’ve been using the Moondrop Chu 2 for around 5 months, and I’m really happy with them overall. The size is very good – small, lightweight, and comfortable for long sessions. They fit well in the ears and don’t feel bulky at all.
In terms of sound, they’re excellent for the price. Clear mids, detailed highs, and a balanced tuning that works great for vocals and instruments. They still feel solid and well-built even after months of daily use.
The only drawback is the bass – while it’s clean and controlled, it’s not very strong. If you’re looking for heavy bass, these might not fully satisfy you.
But if you want clarity, balance, and detail in a compact design, the Chu 2 are a fantastic choice.

Very good value for its price range,
Solid build, durable metal shells
Comfortable fit and decent ergonomics
Tuning flexibility thanks to interchangeable nozzles
Soundstage depth isn’t exceptional (though width / height are decent)
The black nozzle for brighter tuning is a bit aggressive.
