Description
Enjoy a ground-breaking performance with the 64Audio U4s. This hybrid quad-driver IEM features the same patented audio technologies like tia and Apex Core developed for flagships at an irresistible price point.
Created For You
Experience a light and engaging sound with impressive sub-bass without compromising mid-bass clarity with the 64Audio U4s. Its balanced mid frequencies and pleasant high-mid band perform well with various music genres and recording styles, without causing listener fatigue. The tia high-drive r's airy quality and the extended sound-stage from the Apex Core technology provide a lifelike and immersive listening experience.
Tuned For You
The 64Audio U4s achieves a powerful, deep, and enveloping sound without sacrificing clarity, thanks to its dynamic driver. Its frequency response follows proven targets for fidelity and preference, avoiding muddiness and excessive mid-bass. The mids are revealing and contribute to its wide stereo imaging, while the high frequencies strike a balance between neutrality and detail, offering the perfect blend of presence and body.
Beautiful Blue
The 64Audio U4s features a Slate Blue shell with a unique faceplate inspired by Muonionalusta meteorite fragments. The colour was influenced by beautiful blue-dial timepieces and the illuminant properties of the shell and faceplate give it a distinct look in different lighting conditions.
Listen with the Best
The U4s boasts an ergonomic anodised aluminium shell that contains a single dynamic driver, two balanced-armature drivers and one patented tia driver. Its four-way crossover is further enhanced by the proprietary electronic low-pass filter, reducing low-frequency distortion. The ultra-low impedance premium silver-plated copper cable guarantees uninterrupted signal transmission.
Put a Lid on It
The different source amplifier output impedances of smartphones, DAC/Amps, Hi-Res Audio Players and more, can cause the frequency response to varying across devices based on the increase in resistance. A patented Linear Impedance Design (LID) circuit corrects the non-linear electrical resistance of the multiple drivers sets to restore proper interaction with the source device. It preserves the desired sound signature while staying constant and reliable.
Enjoy Your Music with tia
The U4s’ patented Tubeless In-Ear Audio (tia) system reduces unwanted resonance and distortion for a transparent and lifelike sound. This is achieved by allowing the Dynamic Driver and 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.
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 64Audio U4s uses the same electrical low pass filter, developed for the outstanding U18s, which reduces distortion while eliminating unwanted target frequencies before they reach the driver.
Apex Core Technology Looks as Good as it Sounds
The Air Pressure Exchange (Apex) Core allows a seamless airflow to the solid anodised aluminium shell that uses a perforated grill on the elegant faceplate to prevent the obstruction of air for effortless reproduction of music and minimal physical fatigue. This patented vent releases air pressure for better comfort and lesser fatigue while enhancing noise isolation. This technology comes in four module variations: mX, m12, m15 and m20.
Know Your Modules
- mX: Provides wide imaging with reduced noise isolation and a decreased sub-bass response. Perfect with recordings that have more spatial information and less sub-bass content. The reduction (by 1db-10db at 350Hz-20Hz) in the sub-bass response creates a slight emphasis on the high-frequency band.
- m12: Developed to address concerns from users who found the bass drop between m15 and mX to be too significant by reducing bass by 1dB-4dB at 130Hz-20Hz. Ideal for tracks where the bass is slightly overpowering other frequencies and can provide increased mid-range punch.
- m15: Enhances the audio staging by creating a natural and less localised sound. It also provides a better panning blend, resulting in a more cohesive and immersive listening experience and an accurate target frequency response curve.
- m20: Increases sub-bass response while keeping the mid-bass clean, making it ideal for bright mixes and modern pop music. While the sound-stage width is reduced, it works well for synth-heavy tracks and unlocks missing sub-information in older rock recordings.

It surely increases all parameters of sound quality like stereo effects, all frequencies, soundstage and imaging.
I am saying it based on using it with EPZ Q1 pro, Simgot EW 300 DSP with hiby R4 DAP for a week now.
Highly recommend to upgrade existing budget IEM.
Although Cable is thick, its very much flexible and handy. No issues of handling and carrying it because of its thickness.
It's thickness add charm to overall looks of IEM.
Super Bass and ultra clear vocals in
affordable price..
REVIEW AFTER ONE MONTH DAILY USE
Initially, my set up was 'Samsung S 23 ultra + Simgot ew 300 DSP' for daily music listening hobby.
While upgrading from this set up, 1st I bought HIBy R4 DAP, used it for 10 days with same IEM and then decided to go for another big upgrade for iem. After trying existing iem on multiple phones, surprisingly I observed that 'Hiby R4 DAP' is superior even on high-end phones in terms of sound quality.
While upgrading IEM, I kept below criteria and told Mr. Pritam the same.
1. IEM with crystal clear sound with all details & balanced sound.
2. Ultra wide Soundstage & clear imaging
3. Clear stereo effect
4. It should separate Instruments sounds when there are multiple instruments in song/music.
5. It should handle bass heavy songs without compromising vocals & trebles.
6. Comfortable for long hours.
Now after using it more for one month, I can say that -THIS IEM HAS FULLFIELD EACH REQUIREMENT & ASPECT OF SOUND QUALITY.
Only downside I felt that Packaging and Case should be premium in this price tag.
EXPERIENCE WITH AUDIO STORE -
I had some options for IEM in my mind based on previous listening sessions at audio store office as well as youtube & web reviews.
I recently visited audio store office two times for some other product requirement, All those previous options, I tested all of them again. I found that Mr. Pritam's suggestion to buy MK3 over other IEMs is worthy.
Thanks a million Mr. Pritam for always helping & guiding before taking any major purchase.
Superb Cable!
Works well with Zero 2
Value for money product
I am very thank full
I really like the quality of the product not only that I really like your store Too
I want to work with your company as a employee please let me know if there is any openings
I'm an IEM guy and after a long time I've been really impressed with a speaker. And at such a fantastic price point. The sound is so smooth, you can listen to it for hours without feeling fatigued, and most important thing for me was, it sounds just as good on low volume when you want to listen to something in the background, but have guests and are going to talk over it.
Incredible separation. Very good stage, fills a 10x10 area nicely (with windows closed). Bigger area and you might feel the need for two of them (heh). Excellent details on both the bass and treble. This is very much a fun sounding speaker. Female vocals are slightly more recessed than the male ones, but the separation will ensure that they come through nicely nonetheless. Drums on this thing are just a blast (literally!). Strings are so melodious.
Last but not the least, looks are killer. Everyone notices it instantly (although it blends very well with the home decor) and asks what it is. Pick it up. You cannot go wrong.
This headphone needs some time to be given. I have sold these 2 times and bought again and now they are permanent in my collection. I now understand them and you need a seriously good amplification system and then they are much more of a lushfull/true/audiophile sound that surpasses almost all headphones under Rs. 50000 easily (including Hifimans).
It has a satisfying amount of bass
Crispy treble region and clean sound signature
Comfortable fit
Pair it with a good DAC and see the magic happen!!
Must have IEM!!

Great product , comfortable for median and large size ears, bass is mid-level, nice gift packing
Comfortable fit, perfect for long listening sessions.
It's affordable yet can punch above 5 times the cost bracket. The planar soundstage is massive. Separation is great. I love the red filter. Jazz, blues, and instrumental sounds mind-blowing. Worth every penny
The case is really good and keeps my IEM safe.
Top-notch product, exceeded my expectations.
