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

Best Treble around it's price. Super airy but still smooth. Bass-scoop isn't as bad as I thought, but those who want mid-bass - avoid it. Jays Audio Youtube Channel
8.1
Reviewer Score
Limited to 50 units. A huge improvement fit wise versus the original. Great TOTL all-rounder. Great sub, upper mids and treble. Mid-bass is an improvement but still not boosted. Great technical chops while fixing the sense of plasticness the original had.

See Helios but with more mid-treble and mid-bass. Precogvision Youtube Channel
