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
Nio
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.

Very helpful in maintaining type C cable
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.
Excellent studio quality clear natural audio with good enough bass, well-balanced thanks to the audio store team and Pritaam Halpawat sir, great customer service, and 100% authentic genuine products.
Great
Nice I like it.
I was using Sennheisers CX80s with Samsung Galaxy A52s and it has 3.5 mm jack but the sound quality & output levels are very bad. So, I had to get a DAC and I watched a lot of reviews before making this purchase and one thing I can say is the sound quality is better than Apple's dongle becoz it only supports 16/44.1-48KHz .
The cable is super flexible and supports both Type C & Type A connection for PCs.
These IEMs have a unique personality and it does match the many YT reviews that I watched before making this purchase.
The tuning is very neutral leaning slightly bright. These IEMs will present all instruments and everything that is present in the mix without emphasizing. Bass and sub bass present without any mud or overpowering of other frequencies. Mids are well presented, in fact these are all about the mids which are mostly neglected in favour of bass tightness and extended treble.
I found the vocals slightly forward but not harsh, in fact nothing is overpowering in the presentation here which may come across as boring but it is simply presenting the songs as is. You can easily drift off mentally while listening, the presentation is so neutral and focus back whenever you wish to.
Overall these are very solid IEMs good for analysing and casual listening both. Tuning preferences may be highly personal and there may obviously be many who may not prefer this kind of tuning but still this doesn't take any points away.
I am happy with the purchase and prompt delivery.
have been using this for more than 2 months. The audio is very clear specially the vocals and the bass is also decent overall very balanced sound
At the price, can't complain.
Perfect sturdy piece to carry(not in pockets) anywhere
Truthear Hexa fits perfectly.
This IEMs delivers excellent sound across all music genres and is used daily. The unboxing experience is premium. However, a minor issue has been identified: the right-side IEM produces a subtle noise when tapped while worn, which may indicate a manufacturing defect.
DAC sounds perfect when you connect it with laptop or PC
has a less sound when you play with Smartphone.
Other than this the IEMs are great
Great fit to ears
This DAC is awesome and a perfect value addition to my IEM. It enhances the quality of the audio and make it a bit loader as well. Buying and its a must have accessory for the audiophiles.
Powerful, stylish, worth the price, good mic quality, the best in the range!
Powerful performance with good looks
I like the simple design without any text. The material is good. The size is perfect for carrying DAC - IEM - any other accessory.
