Thieaudio's tribrid flagship — dual 10mm composite dynamic drivers (IMPACT2) + Knowles BA + Sonion EST — delivering a slightly U-shaped signature with powerful, textured sub-bass, clean natural mids, and airy extended treble. Studio-monitor tonal accuracy with bass that actually hits. One of the most technically accomplished IEMs under $1500. Best for music of any genre at reference level, cinematic movies with real bass depth, and gaming with elite imaging precision.
