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.

Best Budget IEMS. This was my first time buying this iems and i didnt got single complaint for this. its just good for this price point
New on this IEM journey and I must say they sound better than my 3x priced headphones.
I like the sound and clarity.
Coming from Juzear Defiant and Punch Audio martilo, I would say that this is the best I have till date. Excellent in terms of clarity and technicalities. Being a medium sized IEM it is very comfortable for long listening sessions. Kudos to TAS for their excellent service.
I visited the experience store at Pune and Pritham and his asistant were very warm and welcoming. They patiently explained the pro's and con's of the Hidizs and gave me alternatives to try like the Truthear Nova and Simgot Supermix. Experiencing the different IEMS helped me maake a solid choice of what I wanted.
Also took time to sample an open back Sennheiser HD660S and the Hifiman Sundara. Was able to clearly make out the differnce betweeen a planar magnetic and DD. That helped me know what my prefernces were. Truly enlightening experience ended with a great purchase in the HIDIZS MP145.
These are my first IEMs. After a bit of research, I decided to go with the KZ Castor Pro as my first IEM. I'm really impressed with the audio depth, the crispness of audio and the clarity and separation of instruments and vocals. The music feels much different than the usual TWS earbuds which I was using before! The packaging was good, and delivery from Audio Store was good! Glad to have officially entered the IEM clan!
The Audiocular Spark DAC is amazing and it really enhances the audio quality compared to using my IEMs directly on my PC. The build is excellent, durable and it also comes with a carrying case. The packaging and delivery were both good. Really glad I bought this from here!
Unbelievable this TANCHJIM Bunny Type-C DSP whenIwas unboxed and listen immediately lheard totally theatricale experienced.It'stotally mesmerized me in sounds. In this price unbelievable soundquality. That's why this TANCHJIM Bunny Type-C DSP is more value than itsprice. Thanks once again to Pritam ji for suggestingme so wonderful IEM.
I herd of them and brought them was concerned but the audiostore team was gental and the quality of product was superior
Sound quality is very very neat and clean and in depth. Best purchase ever.
It's an amazingproductforthe price
I purchased these during christmas- and my initial impressions were that these were packaged well, and felt very premium in hand, except for the cable.
The bazz is very lacking, and the iems are unusable without tuning. After tuning these sound full, and have beautiful clarity. Definitely recommend if you can tune them. Also very good for video editors and others who need stock audio
It sounds wonderful 👍
I am very satisfied with my purchase and currently enjoying hi-res audio with my iem. Best looking and build quality is also good under 1K
This is my first IEM. I like the way it sounds. Though I expected much better soundstage but it is good. After using this, I will definitely buy my second IEM. Trust The Audio Store, they delivered as expected. Actually someone suggested me on reddit to go with audio store and I will definitely recommend others the same.
Just got some time with these and here's my honest take:
Comfort: These things are stupid comfortable. Lightweight shells that disappear in your ears, zero fatigue even after long sessions. Stock tips are meh though—nothing special, you'll probably want to tip-roll.
Sound:
- Vocals are pushed forward and warm with less sparkle/energy up top. Great for that intimate, smooth vocal presentation but not if you want bright, analytical vocals
- Bass is elevated and textured but definitely not basshead levels. Hip-hop/EDM heads will find it lacking
- Treble rolls off early = excellent sibilance control. Zero harshness or fatigue, perfect if you're treble-sensitive
Who's this for? Warm vocal lovers and anyone tired of harsh, sibilant treble. Long listening session champs.
Who should skip? Bassheads, treble sparkle chasers, people wanting analytical/reference sound.
For the price, these carve out a nice niche—they're not trying to do everything, just warm and smooth really well. Worth it if that's your vibe.
