Hi,
I’ve had a chance to compare
u12t and
Solaris, so I’ve decided to share a few very brief thoughts... I’m not much of a reviewer, though. I don’t want to comment much on a fit (nor based my review on it) because Solaris housing is huge, and it wasn’t much comfortable for me - after a long listening my ears even hurt because the diverging nozzle pushed my
Antitragus/Antihelix. However, for the time of comparison I was able to get I good isolation with both – I’ve found some ear-tips after some serious tip rolling.
Bass: I’d say equal from a certain point of view -
u12t is faster, the punch is there (for BA) as well as the precision – I’ve found the bass accuracy on high level with both – bass instruments as well as electronic bass.
Solaris doesn’t hit deeper, about the same as u12t, but the bass is wider (overall the sound has more openness and spaciousness) and response leaner with a longer duration, which might cause a feeling that the lows frequency extends much more than in the case of
u12t, but it’s mostly the mentioned duration thus the bass is “
more fun” you can enjoy it more. Anyway, it’s typical difference between balanced armatures and dynamic driver bass – very high standard in the case of
u12t, good enough (depth / resolution very good) but very well-balanced hybrid rendition with mids and high in the case of the
Solaris. (
No winner here, I’d favour Solaris over u12t a bit because I enjoy the bass more).
Mids: u12t is more natural, even though not reference tuned.
Solaris are somehow backward in comparison to
u12t, even though
u12t mids are not the clearest and optimally positioned as I’ve heard from an IEMs. Listening to a solo without instruments or background music, the vocals sounded nice on both, Solaris was maybe a little bit better here - they made everything sound more “3D”, while
u12t sounds more focused and thinner. Vocals with background music and instruments (either pop, orchestra, electro, jazz, rock’n’roll, alternative modern genres, etc.) sounded better on
u12t, imo. Vocals are more forward in comparison to
Solaris. (
I’d prefer u12t, just for the vocals. Vocals are my favourite parts of songs (while I enjoy classical music as well – like opera) and while both performed solid, I have other favourites).
Treble: Firstly, I’m slightly treble sensitive thus I sometime found the treble annoying.
Solaris performs very solidly (hard to find any downsides here nor anything amazing either except for the openness and extension – this shows how were balanced
Solaris is) while
u12t is significantly brighter. If you are treble-sensitive
u12t treble might become annoying in certain songs. On the other hand, brighter sound is typical for most of the 64audio IEMs. (
I’d prefer Solaris as a better all-arounder, the reason is that I'm treble sensitive. In case the song isn't "screaming" I'd prefer u12t).
Observation:
- Solaris is much more source dependant and more “hissy”.
- Solaris performs way better in the low volumes, you have turn the volume up significantly to hear u12t shine.
- u12T is more musical - I mean, the goal of 64audio to be focused on musicians is obvious.
- Technicalities and instruments interpretation go in the favour of u12t.
- Layering is about equal.
- Solaris sounds more fun in a way (everyone defines fun sound differently ).
- Instruments are separated on both about equally, but u12t is much more precise, while Solaris is much more open and spacious.
- Resolution is about equal.
- Soundstage and openness go in the favour of Solaris (TOTL performance).
- u12t is brighter and more natural (still far from neutral).
- Both are good all-arounders.
- With u12t I liked ear-tips with thinner nozzle (Final E, Sony Hybrid Tips, SpinFit) while in case of Solaris ear-tips with wider nozzle (Acoustune 07a, Azla, Symbio W).
- The good solution for Solaris if the nozzle makes a pressure to your outer ear are Azla ear-tips – its shape is longer thus deeper insertion and solid sound isolation.
Please, take all of this as my own opinion which usually differs from person to person, not as a dogma.
