It's a solid set, with great build quality, but sonically isn't the specialist that I want it to be.

This has a really natural midrange, best BC iem I've heard by far.

Youtube Video Summary

Large, sculpted shells with a bulbous rear (housing the bone conductor) make the Aful Dawn-X a substantial fit—comfortable for some, but risky for small ears. The stock cable feels quality but is 4.4 mm-only, and the case/accessories are tidy; importantly, the nozzle grips tips securely (unlike some past AFUL sets). Overall build is handsome and premium, with fit being the main variable.

Sonically, the tuning favors sub-bass over mid-bass, pairs rich mids with smooth, natural treble that avoids harsh spikes yet has mild 4–6 kHz energy, and presents a cohesive, almost speaker-like soundstage. It wakes up with a bit of volume/power, prioritizing clarity, micro-detail and air over outright slam; the bone conductor subtly supports the midrange more than the lows. At $1,300 it’s competitive for listeners chasing technical refinement and a natural tonality, while value seekers or mid-bass lovers may prefer cheaper AFUL options or sets with more punch.
