Who wins on what

Ranked by what users actually praise

Overall Impression

Sound signature splits listeners between 'accurate' and 'boring'. Musicians and classical/jazz fans praise the FA9 for sounding like a studio recording rather than an artificially 'fun' tuning, with clean measurement graphs suggesting deliberate accuracy. But other users call it lifeless, cold, sterile or boring, particularly compared to FiiO's hybrid FH7, which several commenters preferred for its dynamic-driver presence and impact, especially at higher volumes or with faster, bass-heavy genres like grindcore and rock.

Missing dynamic driver is the most repeated criticism. Multiple commenters flag the absence of a dynamic driver as a dealbreaker, saying all-BA IEMs are inherently bass-challenged and dry-sounding. Some wish FiiO would add a DD like the FH-series or fit a bass switch (as on the Q1 MKII) across a single driver to avoid muddying mids. Others counter that the bass switch settings (S2+S3) provide a workable, analytical bass response for those who adjust expectations.

Build quality and connector design earn consistent praise. Reviewers repeatedly compliment the FA9's housing craftsmanship, comparing it favorably to other FiiO models and competing sub-$1000 IEMs, attributing a premium feel to its 3D-printed acoustic construction. The right-angle MMCX cable connector is seen as a smart, protective design choice for portable use, reducing wear when pocketed, though some wished for a balanced or interchangeable cable option included at this price point.
