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

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.

Clean, impactful bass, great detail, fast transients. Upper mids are a bit intense, bright treble, planar timbre.

Has the planar advantage with most of its disadvantages and a reasonable tonality.

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

  • Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.

Average Technical Grade

Decent midrange performance - balanced but unremarkable. Adequate clarity for most genres without notable flaws.
