The Audio Store's Take on the 64 Audio Solo:
The 64 Audio Solo is a remarkable IEM featuring a 14.2mm planar magnetic driver, delivering an impressive blend of musicality and detail. With its elegant copper faceplate, lightweight build, and premium OCC copper cable, the Solo offers both style and comfort. Its W-shaped sound signature combines fast, clean bass, rich midrange vocals, and detailed, engaging treble. Whether you're a planar headphone enthusiast or an audiophile seeking lifelike sound, the 64 Audio Solo stands out for its balanced, natural tonality and immersive listening experience.
Introducing the 64 Audio Solo

The 64 Audio Solo is a revolution in portable high-end audio, offering full-range sound with a single planar magnetic driver. As the latest addition to the renowned tia™ line of UIEMs, Solo brings forward a rich heritage of innovation. By integrating groundbreaking technologies like Helmholtz resonators and electronic filters, it redefines sound tuning in single-driver IEMs. This remarkable design takes inspiration from past successes like the Fourté and Trio models while introducing new acoustic advancements to elevate the listening experience.
Planar Magnetic Driver: Precision and Detail
At the heart of the Solo is a 14.2mm planar magnetic driver, delivering remarkable transient response and high-frequency detail. Unlike traditional dynamic drivers, the planar driver’s diaphragm moves uniformly across the magnetic field, eliminating uneven movement and enhancing sonic precision. This ensures a full-range, high-resolution sound, usually requiring multiple drivers, from a single planar driver.
Helmholtz Resonators: Sculpting the Frequency Spectrum
The Solo introduces the world’s first Helmholtz resonators in an IEM, enhancing its acoustic performance. These resonators are 3D-printed into the sound chamber, precisely targeting problematic frequencies by resonating air at specific frequencies. This innovation provides a more controlled and refined high-frequency response, showcasing the true potential of planar technology.
LID®: Consistent Sound Across Devices
64 Audio's patented Linear Impedance Design (LID) compensates for electrical resistance variations that can occur when using different source devices. This ensures that the Solo’s sound signature remains consistent, whether connected to a smartphone, DAC/amp, or high-end digital audio player, preserving the intended sonic experience.
Apex® Core: Pressure Relief and Comfort
The Apex core technology integrated into Solo relieves pneumatic pressure, allowing for extended listening without discomfort. This design provides the listener with a natural, unoccluded feeling, enhancing spatial perception and delivering a highly immersive sound experience. The Solo’s ergonomic fit and balanced isolation make it perfect for long listening sessions.
Sound Signature: Dynamic and Immersive
The 64 Audio Solo delivers on the brand’s promise of musicality, balance, and detail. Its planar driver provides agile and precise sound reproduction, revealing subtle details within the mix while maintaining a cohesive soundstage. With acoustic notch filters and Apex core technology, the Solo’s high frequencies are expansive, while the bass offers substantial impact and deep sub-bass, creating a dynamic and textured sound experience.
Copper Eight-Braid Cable: Superior Connectivity
The Solo comes paired with an OCC Copper eight-braid cable, designed for low impedance and superior sound transmission. Available in both 3.5mm single-ended and 4.4mm balanced configurations, these cables ensure reliable connectivity while offering a durable, tactile feel.

Let customers speak for us
from 4996 reviewsThis is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.

This is wonderful product and quality is great. Very good working with mic.
And support samsung s22 ultra.
The Moondrop Blessing 3 is a hybrid IEM with excellent performance and a largely neutral sound signature with a slight bass boost. It offers impressive detail retrieval, resolution, and instrument separation for its price.
Pros:
* Excellent detail and clarity: It reveals subtle nuances in music.
* Balanced sound: Largely neutral with a well-controlled bass that doesn't bleed into other frequencies.
* Good technicalities: Strong imaging and separation of instruments.
* Comfortable for wearing for long periods
* Solid build quality
Cons:
* Fit can still be an issue for those with smaller ears.
* The cable could have been better.
Overall an excellent IEM for me.... Well done Moon drop!!!
The KZ ZSN Pro 2 offers exceptional sound quality at an affordable price. With a hybrid driver setup (1 dynamic + 1 balanced armature), it delivers a punchy V-shaped sound signature with deep bass, clear mids, and sparkling highs. The soundstage is surprisingly wide with good instrument separation and imaging. Build quality is solid, featuring metal faceplates and a comfortable, ergonomic design. While the cable and accessories are basic, the overall performance makes the ZSN Pro 2 a fantastic value for budget audiophiles.
Yes it is very comfortable 👍

Best under 2k for balanced sound.

Rarely do you find cases that offer this kind of value. I love it for two main reasons: there's no need to cram your IEMs like in typical compact cases, and it has enough room to fit a dongle DAC comfortably. You can even carry two IEMs if needed. The build is solid, and it feels premium all around. A great pick!

Suggested by Pritam—bought them and loved them. Insane value for the price! A must-have for beginners exploring the tip rolling game. While they mimic some branded ones, the material and build do differ—but the value is unbeatable. Highly recommended!

Purchased a iem from them.Nice packing safe delivery. Will definitely recommend beginner audiophiles to buy it from them.
