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.

It's a solid set, with great build quality, but sonically isn't the specialist that I want it to be. Jaytiss Youtube Channel

Fantastic colored tonality with options, and the unique technical qualities to back it up. M12/M15 modules recommended. Precogvision Youtube Channel

This Planar lines up with the 64 Audio house sound. There are better options for Planars and this sound signature.Super* Review original ranking

Warm and shimmery with excellent imaging. Dampening in the mid-treble elevates this above the standard planar IEM experience. Precogvision Youtube Channel

It's nice, but is planar and kinda dull. Jaytiss Youtube Channel
