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.

Awesome headset
It was such a great MP3 player for the price. There was enough space as 32 GB memory card was provided. Also, we can read e-books in text format. It's so convenient during travel. FM radio is also present. Lot's of features in that small gadget ❤️.

The ear tips are good for starters and do have variety so I'm sure you'll find something comfortable. It can revive your interest in your old IEM's don't expect much as they are just there to deliver comfort to your ears.
New experience with the iem
Amazing sound very addictive ear phones might have been perfect if they came with c type connector
Build quality and audio clarity

Kudos to makers/seller for making it to available.
Purest form of audio hearing experience with this cable.
Happy with the purchase.

The build quality of this cable is top-notch. I’m using it with my HD560S connected to a laptop via Apple Music, and the difference is noticeable. The bass feels tighter and especially welcome improvement for openback headphones and there's a clear boost in instrument separation and overall clarity. Upgrading to a balanced connection has definitely proven to be a worth while decision.

The Hisenior Mega5EST is a reference-quality IEM tuned with taste and subtlety. It doesn't shout for attention but rather invites you to listen deeper. If you're looking for an IEM that balances technical excellence with musical emotion, this one is a rare gem in the hybrid space. A true “listen for hours, forget the gear” experience.

This is the best MP3 player you can get for this price.

I'm new to the world of IEMs and this one was bought to try how it feels. Trust me, it won't disappoint you. Double the value compared to headphones of the same rate.

Budget king SMSL RAW MDA1. Very versatile music dac & headphone amp. Fully satisfied. Being an audiophile I was searching for best budget one got this from The audio store. Thanks for timely delivery. Nothing can match it at this price range period.

Works well with my Moto Edge 50 Pro. Other DAC's would have a lot of interference and static, the Moondrop Echo A has none. Audio is clear and the connector does not heat up at all. Battery life isn't impacted as well.
The build quality is excellent, cable is flexible and will fit in any iem carry case as well.

This is a great product with excellent sound quality. The bass is impressive and it's worth the money.

Beautiful and heavy duty balanced cable. Adds a weight to the music's bass i.e. tighter bass response.
Good product excellent sound well packed but delivery was delayed by two days.otherwise everything good.
