Soratune is a relatively new brand in the Chi-Fi market, and for your information, they are sister of the well-known Chi-Fi brand Letshouer, which has a reputation for providing great products. Currently they have released two IEMs: the entry-level one Bi01 and the higher model Yi01, which I'm discussing now and has positive reception.
This IEM uses dual dynamic coils. We all know how this type of driver tends to provide excellent bass, natural timbre, and clean sound. Before diving deeper, let's first look at the non-sound aspects, starting with the Packaging and accessories:
The IEM offers clean and minimalist packaging, medium in size, with everything well organized. Inside, you’ll find:
- The IEMs
- Cable
- 6 pairs of eartips
- Case
- Some instruction papers & warranty
While there are no additional frills, all the accessories meet basic needs. The IEM cable uses silver-plated materials and offers a choice of mic/non-mic types, with termination options of Type-C or 3.5mm jack plug. I choose the non-mic version with a 3.5mm jack because I prefer using IEMs solely for music and I'm not a fan of Type-C, as I like pairing with a DAC or my LG V60 phone jack to fully elevate their potential "matter of taste and preference". The cable material is quite good; it’s not a thick braided type, but slim and soft, also it less prone to tangling too.
Build, Design, Fit
The build quality of the IEM feels solid, made from lightweight but sturdy CNC aluminum alloy. The design of the Yi01 is quite attractive, reminding me of the Tanchjim 4U and Tri Draco, with its rabbit-like shape. This design provides a snug fit and great isolation. The choice of a slim, comfortable cable also adds to the overall comfort.
Pairing & The Sound
This IEM has a 9ohms and a sensitivity of 101 dB/mW that make fairly easy to drive.. also for me The Yi01 is not particularly picky about source pairing, My LG V60 does the job, but better sources will surely enhance the sound even more. I’m pairing it with the iBasso DC07 and using Divinus Velvet eartips for testing..
My initial impression straight from the box is that this IEM has quite clean sound, with balanced sound across all aspects.
Bass
The low-end here is fun, with a great thump and nice rumble. The sub-bass has texture and a satisfying rumble for hip-hop, R&B, and even K-pop, making it very enjoyable. The mid-bass, while not overly hard hitting one, but still offer great puncy and a natural decay—not too slow nor too fast—so it performs well across many genres, except for metal, which requires quicker decay.
Midrange
For me, the midrange of Yi01 is its standout feature. It's quite balanced, with the low-mid offering nice weight without being too thick, which could lead to congestion (if it doesn't get done properly).. The upper midrange has great control, avoiding shoutiness or harshness while still providing clarity for high-pitched female vocals. This midrange type suits a variety of vocal types, and for those sensitive to sibilance, this IEM is relatively safe. There’s a hint or peaks on certain tracks, but compared to other models in a similar price range, i can say one of cleanest.
Treble
Treble isn’t the crispiest but offers good clarity to the overall aspect. The sound of guitar strings is enjoyable, and cymbal strikes remain fairly clear and has natural timbre without metalic or artificial sound. But don’t expect it will satisfy trebleheads, but for those who appreciate clarity without piercing treble, this IEM deliver it to you.
The Technical aspects hold their own as well. The soundstage offers a surprising amount of immersion, making it great for listening to live performances or recordings. The 3D imaging is accurate, so the “gaming” label isn't a gimmick. I tested it with some game such as Apex Legends, and it performed very well, allowing me to pinpoint enemy footsteps easily. The resolution is decent, but don’t expect the level of detail you’d get from more analytical or highend level set. But, for the asking price, it’s pretty good..
Some Comparison
Vs Tri Draco ($59)
These two has same 2DD configuration. In my opinion, the sound signature is pretty similar, with more puncy and depth bass in the Soratune.. The midrange of both is one of the cleanest in their class, but in terms of note weight I think Soratune stands out here.. but for upper-mid or female vocals, Draco feels more open. The treble both of them is safe and balanced, with the soundstage being slightly wider in Draco because it's has large vent or open-back.. However, in terms of detail and imaging, I think Soratune a bit excels for me.
Vs Letshouer DZ4 ($89)
In my opinion, the tuning is quite different. DZ4 is more warm and laid-back, while Soratune is more balanced or neutral. The bass here, I think DZ4 has the edge in the sub-bass with more texture, while the midbass in Soratune feels punchier. The midrange here depends on preference; if you like thick low-mid, then DZ4 better choice. For upper-mid, I think Soratune feels more open, especially for female vocals in J-pop songs.. The treble in DZ4 is more laid-back, making it warmer and leaning towards dark sounding, while Soratune still sounds crisp and airy in the treble, although it's not for trebleheads level either... In terms of technicalities, both are equally good, with imaging dan separation being better in Soratune if both use the stock cable..
Vs Ziigat Cinno ($99)
it's quite interesting to compare both, as Cinno is one of my favorite IEMs with a neutral and very laid-back sound signature.. The bass here The Cinno has a type of bass that is quite fast with good rumble quality.. The midbass, I think Soratune takes the place with it's punchiness. For the midrange, to be honest, I quite like Cinno; it has more body and pretty sweet too. However, its drawback is that high female vocals feel less open compared to Soratune. The treble in Cinno if you like a more laid-back sound, has treble that is so safe that trebleheads will find it a bit dark.. while Soratune still sounds brighter or better clarity.. In terms of technicalities, if you like a grand, atmospheric soundstage Cinno will give it to you.. Soratune is more open with an airy soundstage, and both almost have the same quality in imaging..
Conclusion
I say it's good start from Soratune, among many IEMs currently available, I think the Yi01 could be a strong contender especially if you're looking for a neutral sound or something balanced across frequencies, from good bass performance to nice clarity in the treble. If you're a treblehead or perhaps basshead, this might not blow you away, but for someone who appreciates a neutral or balanced set, this could be your top pick...
