Reviewer Score
Clean-sounding monitor with great bass decay Occasional splashy cymbals due to the treble extension

7.9
Reviewer Score
Exceptional treble with solid bass. Great techs. Some may find the midrange a bit clinical. Fit will be a dealbreaker to some. Cons: Poor fit.
7.9
Reviewer Score
Top tier clarity and great technicalities, other than a hint of BA timbre plasticness to it. Mid-bass recession is the con in the tuning, turning it into a dry IEM. Top performer nonetheless.
7.7
Reviewer Score
Great technicalities. Lacking that last leg of refinement in terms of coherency. Precogvision Youtube Channel

8.5
Reviewer Score
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
7.8
Reviewer Score
A tastefully colored U12t with a more intimate soundstage, a cutback in technicalities, and more bass realism.
7.8
Reviewer Score
It's a solid set, with great build quality, but sonically isn't the specialist that I want it to be. Jaytiss Youtube Channel
7.7
Reviewer Score
Fantastic colored tonality with options, and the unique technical qualities to back it up. M12/M15 modules recommended. Precogvision Youtube Channel
