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.

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service

Sound quality ausom but not for base lover's

Top notch earphone Mike quality 🔥.gaming, music etc highly recommend ❤️🎧

I believe this is the best tws under 10000 rupees also it is an iem

Thank you audio store. The sound is amazing. It was delivered within time and product was perfect.

Very detail iem for the price not bass heavy

It is compact and yet have a good punch to the output it gives, the packaging was very impressive for the price.

Twilight from Soft Ears seems to me like a benchmark for single DD IEMs. The solid metal craftsmanship is commendable and when it comes to the sound, tonality, song signature and quality is presently benchmark for Single DD IEMs, may be rivalled by the Elder turii ti, which cost 3x of this.

I would really recommend these. I previously used KZ Castor, but these IEMs are a major upgrade. The sound division is really good. The only issues are low bass and high treble. If you want a more balanced or v shape, it is better to use an equaliser. I am using these with Fiio K1 and Audiocular X Tiandirenhe CS-PRO DACs. Both give a nice output.
I don't know if this is specific to Apple Music or IE 200, but when I push the music through an equaliser, I hear a crackling sound (only on hi-res, 24-bit/192 kHz). I will maybe test more on this and will update the review.
Finally, I would recommend it. These IEMs are worth the buck.

One of the best dac amp in budget category, it gives balance output that going well with my performer 8.

It's an interesting product. I like all the tip options in this pack. It's a good beginner pack to know how each tip material can affect the sound quality. All the tip material & quality are good. The silicone tips & foam tips in the pack are good, like those stock tips we get with IEM. But the surprising tips are the latex tip & the hybrid foam tip. Although the latex tip feels a little rubbery in feel & is a dust magnet, but it's very comfortable, provides a good seal and does enhance bass & treble response slightly. And for the hybrid tip, it's like best of both worlds. It gives the comfort of a silicone tip as well as provides the seal of a foam tip. I'm not a big fan of foam tip in general because of how they feel in ear & it's very difficult to put them in the ear, but these hybrid tips removed all those problems for me.

This is one of the best modular cables I have ever seen in this price range. Microphonic is there as the nylon type of material is used for wrapping the cable. But microphonic is very minimal compared to other similar cable I have used. But, once the music starts playing, the microphonic would be gone. connector quality is very premium, on both the 3.5 / 4.4 termination as well as at 2-pin connector end. I love how easy is to replace the 3.5 & 4.4 end. It's highly recommended if you are looking for any premium modular cable on budget. It's one of my favorite modular cables along with the Moondrop aria 2's stock modular cable.

Sounds exactly like the Salnotes Zero with a bit more bass. Has that same Harman curve with upper midrange bump and reduced lower mids making male vocals sound thin. Good resolution/detail and treble is perfectly done. Fit is good and I like that these are very light.

I have own onix aplha as a dac and this is definitely a upgrade in that regards
