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.
They sound just amazing, I would say that the app a little rough to use. I can vouch they sound amazing. better than most of the tws which are out there in the market. Also, the Online dsp, gives a little edge it you want to tune them, and you can also upload your on DSP. Overall at this price point, It' a 10 on 10 deal.
This is a compact amp that has a clear sound output which can be described as slightly warm. Vocals are clear and midst nice. Works straight out of the box. Balanced xlr input is a big plus. Overall it is good value for the price. Will recommend it to everyone
Really a great product for the price offered using thebuds for the first time and it has exceeded my expectations. The sound is more balancednot a thumping bass but withclear vocals, treble and and a surrounding bass. Also there's someissue in connectivity which I faced at firstbut saw a tutorialon resolving the issue online.
everything is great but would have been even better if it had a mic
Awesome case, providing safety
It’s simply great upgrade from KZ. best output at best price
Had received in a day itself and it’s all that I had expected and more.
Very good sound and bass . Clear vocal and instruments
Fosi GR70 is an efficient amp and works well as a preamp as well as a headphone amp. It drives my hd600 excellently.
Amazing quality
Ordered 5 units and all were awesome
Thank you so much
Great part is that it got delivered very next day
I’m genuinely impressed. The sound quality is exceptional—crisp highs, clear mids, and a bass response that’s just right. It doesn’t overpower the mids or muddy the overall sound, which is a rare balance to strike in this price range.
🎧 Sound Signature: Tuned to the Harman Target with a tasteful bass boost. It adds warmth without sacrificing clarity, making it perfect for everything from vocals to electronic music.
🔊 Bass: Not too high, not too low—just enough to give depth without distortion. It complements the mids beautifully.
🛠️ Build Quality: Solid and premium-feeling. The fit is comfortable for long sessions, and the mic is a handy addition for calls or gaming.
Overall, it’s a fantastic value for the price. If you’re looking for an IEM that delivers refined audio with a touch of bass and excellent build quality, this one’s a winner.
Best among its price range. I think it's best value for money till 15k. And best overall sound quality under 10k. It's complete package. This is my first purchase before this, I used Sony WF-1000XM4 earbuds. This is gonna kill to its value for that impressive sound quality.
Good quality eartips. They are very comfortable!
