Letshuoer s12 ultra (One Month of use)
I got the S12 Ultra about a month ago now and its been great so far. I have tried a lot of planar IEMs before but the s12 ultra has to be one of my favorites. I never tired the original s12 but the did have the s12 pro for a while and comparing it to the pro the tuning on the ultra is much smoother. Bass in more punchy and the treble is not sibilant (most of the time).
Compared to the MP145 the stage on the ultra is on par or ever so slightly smaller than the 145. But overall tuning on the ultra is smoother and more refined. Bass texture and layering are better on the ultra too.
Comparing to the KZ PRX, its a U shaped sound and the tuning on that set is done will but the ultra being a warmer tuned set has more warmth to vocals which is something I missed on the PRX. Technical stuff like separation and layering are also better on the ultra. But not as much as I expected considering the price. Overall I think if you are looking for an upgrade to the PRX then the 12 ultra is a good step up.
Comparing to the S08, the ultra is more treble energy. The S08 is a very warm sounding set and sometimes looks like the upper treble is cut off completely. Which I am not a fan of. But for that particular tuning the S08 is good. The ultra has more treble energy without sounding harsh and the sound feels more contrasty and engaging.
Overall the S12 Ultra is worth the price in my opinion. This is not a full review but just comparing it to some other planar sets.
