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.

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