A step down in techs from U12T (possibly a half step down from U6T). But very well tuned and adds in a dynamic driver punch. Timbre is slightly improved compared to U12T due to the increase in midbass and upper mids energy. On the second hand market, 64Audio IEMs are among the best values in portable audio, the U4S is no exception. Previously Owned

A tastefully colored U12t with a more intimate soundstage, a cutback in technicalities, and more bass realism.

I fully expected these to be an overwhelmingly bass heavy set but instead got something quite different. Singularity bass is boomy and somewhat pillowy, extending deep and with almost atmospheric levels of elevation - seriously, just look at that frequency response... Now, pillowy is something that I don't normally associate with quality bass and it goes without saying that this adjective used to describe bass also suggests a lack of impact but it does rumble and there is meat to the bass, just lacking that harder, crisper, leading edge to the attack. And this is bad right? Well, as I am finding out, not exactly. Rather than having bass be the star of the show, instead, the bass serves as a backdrop to mids and treble which take center stage. This quite possibly the most technically proficient single DD set I've heard and trades blows with the IE900, perhaps having an edge in attack and dynamics. Transients are razor sharp and notes are very well defined. Vocals and instruments stand out and apart in the mix in a way that you usually would expect only from sets with multiple BA drivers, let alone one single DD. Timbre is pretty good as well - there is a bit of brightness here but it never is sharp or jarring - it's not the most timbrally accurate I've heard but it also doesn't have anything that sticks out to me as offensive or off putting. Instead, it seems that brightness adds to the sense of technicalities. And this is all with a very significant bass backdrop that surprisingly doesn't bleed or introduce mud into the mix. My theory (and I'm definitely not an expert here) is that if the bass were to be too punchy or impactful here, it would overwhelm the entire sound signature. But that's just my theory. This is a basshead IEM for mids and treble lovers. That said, as great as this set is, I think IE900 still holds the crown of best single DD set because I'm just a sucker for tactile bass and nothing quite matches the physicality to be found on that Senny.

One of the best basses ever inside a very small and comfortable shell. The rest of the tuning is still pristine but the technicalities are bottlenecked by the single DD.
