Great details. Good stage in front but lacking in wideness/3D. Imaging is good and speration is great, but uneven treble peaks. Planar timbre. Vocals and notes can be thin. Fatiguing at higher volume listening.

The most refined S12 to date. Smoothest treble out of all the S12, and very little Planar timbre while keeping up the great tech and detail.

Easily the best-tuned planar IEM by a country mile, the Timeless is also no slouch on the technical front.

Insanely resolving for price. Good planar timbre. Tuning is slight colored but doesn't seem to affect mids as much. Stage depth and width will be the weakest points. QC gamble on first batches. Get S12 instead, imo

Very energetic. Very detailed. Very bright. Noticeable recession in mids - it is V-shaped after all. Planar timbre is quite noticeable and can sometimes make this sound unnatural.
