Vocals and midrange instruments attain extra fullness without losing their articulation and transparency. Brighter IEMs like the Letshouer S12 sound more even and cohesive, especially at a higher volume. The added warmth eases the treble and upper midrange by bolstering the note body, resulting in a more musical presentation.
But it’s the bass texture that really draws me in. The sub-bass notes in the latter half of Caligula’s Horse’s “Daughter of the Mountain” (starting at 5:51) sound gravelly and visceral. In addition, the kick drums hit with impact and assertiveness.
