Description
The U18t took the audio world by storm with its whole 18-driver package. Now, it’s time for something bigger and better - the 64 Audio U18s! This in-ear monitor features the latest proprietary drivers, tia, Apex Core and LID technology as well as a whole new electronic crossover network for an unparalleled audio experience.
Go Tubeless with tia!
The 64 Audio U18t’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 tia balanced armature drivers to radiate freely in the single tia bore with no obstructions in front of the drivers.
Apex Sound & Comfort
The Air Pressure Exchange (Apex) Core allows seamless airflow to the aluminium shell that uses a perforated grill to prevent the obstruction of air for effortless reproduction of music. This patented vent releases air pressure for better comfort and lesser fatigue while enhancing noise isolation. This technology comes in three module variations: mX, m15 and m20. 
Reliable with the Right 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.
No Dampers, It’s Electrifying!
Old technologies like acoustic dampers merely blocked frequencies from reaching the ear instead of preventing it from reaching the drivers. This introduced distortion due to the vibration and air movement at higher volumes. The U18s uses an electrical low pass filter that reduces distortion while eliminating unwanted target frequencies before they reach the driver.
The Best of Nature & Science
Inspired by nature, the U18s is handcrafted in the USA from an aerospace-grade aluminium billet. This is CNC milled, sand-blasted, cut and anodised twice for incredible robustness. A striking fractal design makes it unique and stunning.
Premium Cables
A top-of-the-line IEM deserves a state-of-the-art cable. 65 strands of pure silver-plated OFC wires are combined together in an 8-braid cable. These are covered with a premium sheath to reduce microphonics and unwanted noise.

I own 2 iems from 64a

U12t
This is the best end game iem
Very organic sound with good bass
Very good for long listening
Treble is well extended and very smooth in fact smoother than the U12T
Thanks to pritam for recommending this gem
Thank you for the review! The 64 Audio U18s IEM are definitely an excellent choice for those seeking an organic sound with good bass and extended treble. We're glad you appreciate their smooth quality!
Finesse -- That is the word that comes to mind when talking about U18s. A very cable and source picky IEM, it reveals its might when paired correctly. Vocals have never sounded more emotional, the bass is wide and deep, yet the mids never take a back seat. A dark sounding IEM with a high degree of details, a mind blowing speed and a wide soundstage. My favourite when I just want to immerse myself and enjoy the mellow beats. Comes closest to bringing me to the stage.

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.
