TOTL imaging chops/layering. Tons of micro-details. Bass texture and impact second probably only to the Z1R. Wide and 3D staging. AGGRESSIVE, and get fatiguing when cranked up/long-listening sessions.

Very engaging. I usually prefer something more balanced and neutral, but this IEM has some special sauce. Very well-tuned from bass to treble - with a little bit of spice on top. Great tonality and amazing techs. Imaging is quite phenomenal, separation is great. Very detailed. If you have 700 to spend on IEMs, buy these on the used market and never look back. Warning - treble can be slightly hot. Also, timbre might sound just a tad artificial. Loaner

Great bass and sheer detail, at the cost of wonky treble and not so accurate imaging queues. I find it work the best with eletronic music or modern metal. Still a solid contender to this date at a very good price in the used market.

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
